"Haha, haha, haha, human. Are you kidding?" Then he laughed out loud.

Hearing Cook say this, Dina's eyes were also full of vigilance when she looked at Cook, obviously Dina also thought that Cook's words were false, Cook saw the expressions of Dina and the golden thorn, and took two steps back vigilantly.

"Tell me what's going on?" Diena asked the question in her mind when she saw Cook retreat.

"I can't say this way, only after the golden thorn signs the master-servant contract with me, the golden thorn is qualified to know, even Dina you are not qualified to know, anyway, my conditions have been opened, as for whether you can agree, that's your business. Cook took a few steps back.

Boom, at this time, there was a rumbling sound overhead, and then huge stones fell from the top of the canyon, and through these falling rocks, Cook and the others saw that the huge bone dragon actually wanted to use these stones to bury the three of Cook alive in this canyon.

Cook quickly jumped to the bottom of the cliff on the side of the canyon, and then the thunder tooth in his hand dug hard, and a one-man high cave appeared in front of Cook's eyes, and then Cook did not hesitate to drill in.

"Master, what should we do?" Golden Thorn, who was far away, saw Cook digging into the cave, and Golden Thorn had a similar idea.

"Let's follow up, this human is a bit mysterious. Dina didn't let the golden thorn dig into the cave, but spoke.

When the two of them rushed into the cave where Cook was, Cook's cave had been dug more than ten meters deep, but to the surprise of Dina and Dina Gold, the excavated stone was gone.

"What are you going to do?" Cook asked, looking warily at Golden Thorn and Dina.

In fact, if Cook is alone, there is still a way to escape from the pursuit of this undead bone dragon, Cook can hide in the natural ring, and then let the little arrow leave with the natural ring, but if there are Dina and the golden thorn, Cook really has no way, if something like the natural ring is exposed, I am afraid that as soon as he gets out, Cook will face great danger.

"I think we still have a better chance of surviving together. Dina spoke.

"I'm sorry, I really don't want to be with you. However, Cook's answer made Dina even more sure that Cook had a backhand.

Dina looked at Cook, and then said: "The Golden Thorn is a demigod-level powerhouse, even in the demon world, the number of such powerhouses is very rare, even if it is our Moon Demon Clan, the number of strong people like the Golden Thorn is limited, if you don't say it, how can we be sure that what you say is true or false?"

"If you don't want to, forget it, I won't force it, but I want everyone to go their separate ways from now on. Cook heard Dina say this, and although Cook admitted that Dina had a point, Cook had come up with a solution that could not be known to outsiders.

"Human, don't know what to do, or ....... "The Golden Thorn threatened Cook viciously.

Cook interrupted with a sneer: "Otherwise, why don't we fight now?"

Dina hurriedly stopped the Golden Thorn, and then silently left the cave where Cook was with the Golden Thorn, Cook breathed a sigh of relief, although Cook was not afraid of the demigod-level powerhouse of the Golden Thorn, but Cook was not willing to face it now.

The Golden Thorn also dug a cave not far from Cook, and then entered with Dina, and there was a rumbling sound from inside the canyon, but this did not affect Cook and Dina and the others in the slightest.

"Human, do you really have a way to deal with that skeleton out there?" Kerry asked as he looked at Cook, then asked suspiciously.

"Of course. Cook replied and said nothing.

Then Cook took out a few magic fruits from the Ring of Nature and threw them to the seven little guys in the Lost Plane, as well as Kerks, and began to eat a lot of food himself, in this world, there is no such thing as Bigu, the stronger the storage zài, the more you need to absorb a lot of food.

Just like Cook needs to eat the meat of Warcraft now, as well as magic fruits, if it is ordinary food, Cook can simply eat two cows, this is because the energy contained in ordinary food is no longer enough to support Cook's body's needs.

After Cook finished eating, he continued to dig the cave, because the cave that had just begun to dig was blocked by rocks, and Cook had to dig upwards.

Hours later, Cook was digging hundreds of meters above the ground, and Cook's face darkened, and Cook knew that this was the conspiracy of the big bone dragon above.

"Human, we need to have a good talk. "The golden thorn is dozens of meters away from Cook, where is also the exit of a cave. Obviously, Golden Thorn and Dina also dig the cave like Cook, but in order to avoid being buried alive, they will continue to dig up the hole, and Golden Thorn and the others must have realized that if they continue like this, I am afraid that what awaits the three of them will be a disaster.

"There's nothing to talk about, my conditions remain the same. Cook said coldly.

Cook turned back to the cave and began to think about what the chances of the arrow would be able to escape if he had carried the Ring of Nature, knowing that the giant bone dragon lord was no ordinary commodity.

"Why don't you tell Dina about the solution?" Cook muttered to himself, but then Cook immediately gave up, because Cook knew that he couldn't leak this method, and if it did, he was afraid that Cook would be hunted down by demigod powerhouses in all planes.

"Barry, Barry, I'm going back to the Sanctuary. Cook cried out in his heart.

But this damn Barry doesn't know why, he just doesn't answer Cook's question, and Cook keeps screaming in his heart.

"Cook, I'm thinking about you, we're one now, you're at your current level, it's not good at all, I'm here to train you, I'm here for your good. Barry spoke halfway.

"I've already worked, don't you see that I'm strong now?" said Cook, referring to the incident of his own comprehension of the law.

"This proves even more that my method is right, that people can only exercise themselves faster when they are in danger. Barry said with a heartfelt voice when he heard Cook's words.

"Okay, but I have a request. Cook was so angry that he almost turned his back on it, he didn't expect this Barry to say that, Cook also knew that Barry would definitely not watch something happen to him, but Cook was not stupid until now, and rushed out directly to singled out this bone dragon lord, this is looking for death.

After Barry agreed to Cook's terms, Cook began to dig a huge cavern at a height of a thousand meters in the canyon, which was seven or eight meters high and ten meters wide, and there were five such caves, thousands of meters away from each other.

The next time, Cook was busy in these caves, two days passed, Cook looked at the canyon outside the cave, there was no shadow of the bone dragon lord on the canyon, but there were hundreds of bone dragons flying around in the canyon, and some undead appeared under the canyon, apparently these undead had crossed the canyon that Cook blew up at the beginning.

"Click. Cook stuck a pitch-black metal part where it should be, and there were hundreds of more parts in front of him.

As Cook continued to be busy, the parts were finally assembled, and what appeared in front of Cook was something like an anti-aircraft gun, but there was only one barrel, the barrel was the thickness of Cook's arm, and there was rifling in the barrel.

The barrel was more than six meters long, covered with silver lines, and the base below the back of the barrel was inlaid with fist-sized magic crystals.

"Damn the bone dragon, let's see if my weapon is powerful or yours is powerful. Cook looked at the bone dragon in the sky and cursed to himself.

After Cook finished assembling the huge anti-aircraft machine gun, he took a deep breath, and then his spirit moved, first the magic crystal on the base of the barrel began to slowly light up, and the lines on the surface of the entire barrel continued to light up, and the entire barrel showed a silver glow.

"One hundred and thirty magic patterns, one kilogram of magic silver, six hundred kilograms of pure gold, and specially made magic pattern bullets, I see that your bone dragon lord has high defense, or my weapon has strong attack power. Cook looked at the huge barrel of the gun that had all the magic patterns lit up, and said distressedly.

"But where did the Bone Dragon Lord go?" Cook looked up the canyon at the mouth of the cave, Cook was sure that the Bone Dragon Lord was on it, but when Cook needed the big guy to appear, the big guy didn't show up.

"Roar. The Bone Dragon Lord had no hope, and some small bone dragons, as well as flying undead, appeared in Cook, and rushed over with a roar.

You must know that the hole dug by Cook is at an elevation angle of forty-five degrees, which is convenient for Cook to shoot the bone dragon lord in the sky without being seen by the bone dragon flying in the canyon, but somehow, a flying bone dragon just saw the cave dug by Cook and appeared Cook.

Boom, boom, boom, the hole with an elevation angle of forty-five degrees, the stone wall itself is not very thick, under the continuous attack of the bone dragon, this stone wall is directly attacked by the bone dragon into pieces.

Roar, a bone dragon roared, and a gray-black dragon breath squirted towards the cave where Cook was.

"Damn, bang, bang. Cook quickly aimed the muzzle of the anti-aircraft machine gun at the hole and began to shoot.

Boom, a bone dragon was directly hit by the demon pattern bullet, and then there was a violent explosion, and this explosion even affected several other bone dragons within a radius of hundreds of meters around.

"Roar. Just as Cook fired two demonic bullets, Cook heard a deafening roar, and then Cook felt an overwhelming breath of death.

"Not good. Cook hurriedly dropped the Demonic Machine Gun, and then rushed to a downward cavern in the back.

Almost as soon as Cook rolled into the cave, an overwhelming gray-black flame swept through where Cook had just been, and even a section of the area thousands of meters wide in the middle of the canyon was enveloped in gray-black flames.

"What a powerful dragon's breath. Dina and Golden Thorn hid in a hidden cave thousands of meters high, and saw that the rocks below the canyon were directly vaporized by the gray-black flames, and the other undead under the entire canyon were also directly burned to ashes by the flames.

Dina looked at the golden thorn and asked, "Is that human alright?"

"I don't know, but I've been observing it for days, and that guy has a knack for digging caves. Golden Thorn shook his head and replied.

Cook saw a stream of gray-black flames rushing down the passage, Cook quickly hid in another cave, when Cook looked at the canyon that was still being ravaged by gray-black fire at the entrance of a small cave thousands of meters away, Cook smiled bitterly, obviously, Cook's days of preparation were in vain.

"Damn Scythe Demon, damn Moon Demon, wouldn't it be a very simple thing if you agreed to Lao Tzu's conditions, and this Scythe Demon still has a good chance of becoming a god. Cook cursed quietly.

Barry walked out of Cook's body in a flash and said, "Not necessarily, although I can help that scythe demon ignite the divine fire, but can you guarantee that the energy in that guy's body is enough?"

"And even if you become a god-level, I don't think it's necessarily the opponent of this bone dragon lord, after all, this is an undead creature. Barry then added.

It turned out that Cook was going to trade with the Golden Thorn just now, just to let Barry ignite the divine fire for the Golden Thorn and make the Golden Thorn a god-level master, but would Cook dare to take out such a means? If he takes it out, he will definitely be hunted down by all the demigod-level powerhouses.

But the one who knew that Golden Thorn and Dina were suspicious of Cook and did not trade with Cook at all, and Cook also let the little arrow escape with the natural ring, the chance was too small, after all, under the strong spiritual power of the bone dragon lord, the little arrow had nothing to hide.

That's why Cook only had to make his own magic weapons, but the bone dragon lord flew in the sky, and he first needed this attack distance, and only enough attack distance could allow Cook to wield his strength, so the magic pattern anti-aircraft machine gun was born, but he didn't expect it to be destroyed like this.

"Cook, you have to calm down, first you have to study the weakness of the bone dragon, and then make targeted countermeasures, take your magic pattern anti-aircraft machine gun as an example, the idea is good, but there are a few points that are not easy to achieve, first of all, the size is too large, not easy to carry, in dealing with undead creatures like the bone dragon lord who can fly, I think it is indispensable to be able to move quickly. Barry began.

When Cook heard Barry's words, he also felt that he had taken it for granted, it was good that the magic pattern anti-aircraft shooting was extremely strong, but this thing was too large to be carried, so Cook had a portable surface-to-air missile in his mind, this thing was easy to carry, and after the ammunition was fired, there was only one shooter, which was very convenient.

"Actually, Cook has you thought about it, if you can get close to Cook, or even run into the body of the bone dragon....... Barry said on the side.

"It's not that simple. Cook shook his head, this bone dragon can fly, not to mention alertness, not to mention entering the body of the bone dragon, that is, close to a distance of a thousand meters, Cook estimates that he can't do it, of course, if he really enters the body of the bone dragon, with the power of the thunder fang, Cook will definitely be able to get a considerable chance of victory.

As for Cook's inability to use Thunder Fang, it was because the Thunder Fang attack group attack effect was good, and for an undead creature like the Bone Dragon Monarch, although the lightning energy could also cause damage to the Soul Fire of this Bone Dragon Lord, the effect was definitely not high, after all, the bone defense that constituted the Bone Dragon was definitely high.

Of course, the most important thing is that after Cook uses the thunder tooth to strike with all his strength, his own energy must be consumed a lot, and Cook is now in the demon plane, and there are demigod-level scythe demons around, as well as the moon demons, and the crows, creatures that have lost the plane, Cook must need to guard against it, right?

Cook took a beautiful rest in the depths of the cave, and then continued to work, first Cook was the design of the Stinger missile in the copycat, and he had to arrange the magic pattern reasonably in the design drawing.

And the number of magic patterns can not be less, and on this shooter, there are several major systems, first added, plus two kinds of magic patterns, one is anti-gravity, one is wind, two are used alone, or mixed, this needs to be considered.

And when designing the shooter, the ammunition must also be designed, otherwise the shooter is made, and in the end the ammunition has no way to solve it, and that is enough.

Fortunately, Cook also has some experience in alchemy, and the design drawings have gone through seven or eight days, which is almost over, and this time Cook has made a lot of money.

"Why, a ton and a half of pure gold, five kilograms of magic silver, and a large amount of Mithril, wind copper, Lao Tzu doesn't believe that you, the bone dragon lord, are so hard. Cook took out all the ingredients and said through gritted teeth.

And that's just the shooter, as for the ammunition, that's another matter.

"Click, click. Just as Cook was about to refine, there was a clattering sound.

Cook quickly gathered up the materials, and then quickly entered another cave, turning around and sprinkling a puff of powder, and then the cave that Cook had entered collapsed.

"Damn the undead. Cook cursed in a low voice, and then Cook entered another hidden cave again, no way, now the cave was full of undead, and Cook had to open more, more hidden caves.

Compared to Cook, Golden Thorn and Dina are more wolf-like, although Golden Thorn is also very good at digging caves, but the food that Golden Thorn and Dina carry with them has been almost consumed, and a demigod-level powerhouse like Golden Thorn, if he doesn't eat, he can't do it.

Dina's mage robe has been torn a lot, and the golden thorn also has some scars on his body, which are left by Dina and the golden thorn when they fought against the army of the undead, compared to Cook, Dina and the golden thorn lack food, lack more hidden means, after all, Cook is not only a pharmacist, but also a magic pattern master, the magic pattern can not only fight, but also can warn, but for Tina and the golden thorn, once it is revealed, it will be in trouble.

"Master, why don't we agree to that human's terms?" said the Golden Thorn, looking at Dina.

"Wait....... Although Dina didn't know if Cook was dead or alive, the explosions that broke out on the other side still let Dina and the Golden Thorn know that the human was still alive.

Before Dina could finish her sentence, she heard a clattering sound, and Dina and the Golden Thorn quickly got up, and then moved to another cave, because this side of the cave also had an army of undead entering.
