Ye Fei stepped aside in amusement, and only when Han Sen's gaze came over did he nod lightly and return with a knowing smile.

Since Hansen appeared, it shows that there is still room for relaxation in the relationship between him and Lauren, even if he doesn't need the formula for this magic bomb now, but after so many years, Lauren has tried his best to find the whereabouts of this formula, and this heart is enough to move Hansen. After all, even after losing the recipe for this magic bomb, Hansen still studied the bomb mastery.

The two of them talked in the hut, and the atmosphere between them changed from awkward at the beginning to calm afterward, and finally the two began to talk about many interesting things about the year, and finally became warm.

Ye Fei waited on the side for a long time, and finally, when the two were almost finished, Han Sen handed him the formula for the magic bomb: "Young adventurer, this is what you deserve." Because of you, I have the opportunity to restore friendship with my friend, and this day I have been waiting for for more than twenty years. This recipe is given to you as a thank you gift, and if you are willing to achieve more in the explosives branch of engineering, you can come back to me when you reach the peak of engineering, and I will give you some guidance. ”

"Thank you!" Ye Fei thanked the two masters of engineering before taking over the formula of the magic bomb.

Magic bombs are not a new thing for Ye Fei, his flame burst bombs, ice bombs, etc., those that need various series of magic fans belong to magic bombs. And the recipe for this magic bomb is not a way to make a certain magic bomb to Ye Fei, but a new way to increase the power of the magic bomb. In other words, this is a recipe to improve the bomb making process, which has a very important role for Ye Fei.

"Magic Bomb Recipe (Gold Quality): This recipe records various precautions in the production of magic bombs, and careful learning of this recipe can allow engineers to have a deeper understanding of magic bombs. effect, the power of the magic bomb is increased by 20%-50%. Required: Advanced Engineering. ”

"Very good recipe." Ye Fei saluted and thanked the two again, although he had obtained the formula before, but because it was a task item, he didn't know the specific content of this formula, but at this time, the formula was really good, and it could even be called the best. He clapped his hands, and after learning the recipe, he threw all the magic bombs in the previous package to Miya, and asked her to go to the auction house to sell them, as long as there were new bombs, those bombs made before were useless. And he himself can't wait to conduct research on the new magic bomb here at Hansen.

Ye Fei had a lot of materials at hand, but he only chose four kinds of bombs: Black Iron Flame Bomb, Black Iron Flame Burst Bomb, Black Iron Cold Ice Bomb, and Black Iron Dark Curtain Bomb. The first three bombs Ye Fei had already done enough, but now he just replaced it with a black iron shell, and the magic powder used was of higher quality, so it was more powerful. Of course, the power of the bomb can also be increased after using the magic bomb recipe to improve the skill. As for the Black Iron Dark Curtain Bomb, it is a dark magic bomb, Ye Fei has just learned, and the effect is similar to the dark smoke screen of Patience, which also releases a smoke screen to block the enemy's vision. In the past, Ye Fei basically wouldn't use this bomb, after all, there was Pillus, but now that Pillus is gone, this bomb is particularly important, a must-have for yin people and monster killing.

When Ye Fei was making bombs here, Lauren and Hansen's eyes frequently fell on him, and it could be seen that both of them were very satisfied with him. Lauren sighed and said, "If he wasn't interested in bombs, I really wish he could be my student." ”

"Your students?" Hansen laughed, "No, no, no, he shouldn't be your student, and given his love for bombs, he should be my student." ”

Lauren glanced at him resentfully: "Okay, for the sake of past mistakes, I won't argue with you." Someday, though, his accomplishments will surpass yours. ”

"Of course!" Hansen nodded earnestly, "They are adventurers, blessed by the gods, they learn everything quickly, as long as his talent is not too bad, one day he will surpass me, and I am just a mentor in his life." ”

The two of them muttered here, just watching Ye Fei make one bomb after another, and after making a total of more than a hundred bombs, he took out a lot of materials and began to make the Black Iron Wing Bird. This thing is much more complicated to make than those bombs, but fortunately, he has enough materials and a lot of energy crystals at hand, and after tossing for more than two hours, he finally finished making the first black ironwing bird.

Black Iron Winged Bird (Gold Quality): An engineering item that summons a level 50 mechanical winged bird to fight for you for three minutes. Possess skills: Pounce, Iron Wing Scatter. Cooldown: 10 minutes. Level 42 is required, and advanced engineering is required.

"I still have two skills, ha, this time it's really earned." Ye Fei looked at the miniature version of the winged bird in his hand happily, this can be regarded as a small half pet, although there is a time limit, and he can't add blood, but as long as he is carefully controlled, it is still good.

Hansen on the side looked at the black iron-winged bird in Ye Fei's hand and said with a smile: "Lauren, you are not bad, you even took out such a good thing?" Why don't you send the Buddha to the West and teach him how to make your mechanical healing kits. ”

Lauren snorted: "You think beautifully, mechanical healing kit, this is a good thing, and it is easy not to teach outsiders." ”

Hansen blinked: "Is he an outsider?" ”

"How not?" Lauren glared at him and said, "He's going to learn the explosives branch from you, not the mechanical pet branch from me, I even passed on this housekeeping skill to him, it's too unreasonable." ”

Ye Fei heard Hansen say this, knowing that there must be something cheap to earn, he looked at Lauren seriously and asked, "Instructor Lauren, what is the mechanical healing package, and what conditions do you need if you want to learn?" ”

Lauren sighed and said, "The Mechanical Healing Pack is an introductory assessment of the Mechanical Pet Branch. Any engineer who has learned the Mechanical Healing Pack will become a Master Engineer who specializes in mechanical pets. Its main function is to restore health to your mechanical pet such as the Black Iron Winged Bird, which restores 3% health per second for fifteen seconds. ”

"Hey, this stuff is pretty good." Ye Fei was secretly happy in his heart, he really wanted something, "In addition to the method you said, do I have any other methods to learn?" ”

"Yes." Just before Lauren was about to refuse, Hansen had already preemptively said, "To prove your love for engineering, as long as you donate a hundred sets of black iron ore and a hundred sets of igneous rock mines, he can make an exception to teach you how to make this thing." ”

"Hah, that's easy."

Ye Fei laughed loudly, snapped his fingers, and Xiao Ya, who had been sitting obediently on the side, took out one hundred and fifty groups of two ores each. Ye Fei said: "One hundred groups of ores here are for Mentor Lauren, and the other fifty groups are for Mentor Hansen. ”

"Haha, the little guy is very good at being a man, not bad." Han Sen happily put away the ore, he knew what Ye Fei meant, and he gave him a few words, these are the benefits.

And Lauren looked at Hansen helplessly, without saying a word, he put away the ore and taught Ye Fei how to make the mechanical healing package. When Ye Fei began to make the mechanical healing package, he lowered his voice and said to Han Sen, "Old fellow, you are cheating. ”

Hansen shrugged his shoulders: "I just found a leak, didn't you set this rule?" ”

"However, this rule is that it must be announced to that player only after someone has completed the special mission I announced."

Hansen waved his hand impatiently: "Okay, okay, all those tasks you can complete as an engineer, can you still be difficult to defeat him?" It's just a matter of time, and besides, he's done us such a great favor, what's wrong with getting some good? Not too much! ”

"This ......" Lauren hesitated for a while, but finally couldn't say anything, and sighed heavily.

Ye Fei left Hansen's cabin after making ten mechanical healing kits, which were only needed in some emergency situations, and were not needed at all in normal times. What's more, under normal circumstances, Ye Fei would not use the Black Iron Winged Bird for no reason to kill monsters and level up to do tasks, and he and Black Flame would be enough.

Subsequently, Ye Fei returned to the Moonlight Plain and met with Little Phoenix and Snowy Night Weiyang.

Xue Ye Weiyang asked casually: "The task is completed, what good rewards have you got?" ”

"The power of the magic bomb has been increased by two to five percent, and I have obtained a level 50 mechanical pet formula and the corresponding mechanical healing pack, and overall, the reward is good." Ye Fei said with a smile.

"It should be a big profit." Xue Ye Weiyang himself also studied engineering, but because he was busy leveling, the level of engineering was not high, and he asked with some curiosity: "What is a mechanical pet, and how is the power?" ”

"I don't know, I'm going to give it a try."

As Ye Fei spoke, he picked a level 55 robber and released the Black Iron Winged Bird.

Don't look at the black ironwing bird in the prop state is only the size of a palm, but when it is released, the wings are about two meters wide, and the body length is about seventy centimeters, especially the pair of eyes used as energy crystals, exuding a dark blue light, which looks even more heroic.

The Black Ironwing Bird slammed into it, and a -979 damage appeared above the head of the level 55 bandit, which is not high, because it is also a skill, and it is indeed a bit unreasonable to hit such a little damage. But when I think about it, there is still a five-level level gap between the Black Iron Winged Bird and the bandits, and the damage is weakened in various ways, and it is reasonable that the fight is not high. Then the Black Iron Wing Bird used another Iron Wing scattering skill, it can be seen that this skill belongs to a group attack, more than a hundred pieces of Iron Wing shot out towards a conical range of about 90 degrees in front of it, covering a radius of about three meters, and the damage is not high, only more than 400 points of damage.

But thinking that this was a group attack, Ye Fei was relieved.

Ye Fei himself didn't feel too satisfied, but the snow night on the side was already jealous: "Don't look dissatisfied, in fact, this is already very good, after all, it's just a temporary pet, if it's too strong, players in other life professions will shout again." ”

"That's what you said." Ye Fei smiled, although the Black Iron Winged Bird was a gold-level mechanical pet, but because of the level gap, it was still a little worse than the level 55 bandits, and it was not able to single-handedly pick out its opponent, and in the end, Ye Fei came to help.
