Thinking of this, Han Xiao immediately opened the passage and strode out of the first treasure house, and when he returned to the hall on the seventh floor, Han Xiao looked down at the Soul Refining Ding in his hand, and couldn't help but start to get anxious.

It turned out that the blood inside was slowly clotting, and it seemed that it would not take long to lose its effect. Han Xiao bit his finger again and dripped a few drops of blood into it, and he was a little worried in his heart, if the bone eroding dragon blood continued to be diluted, he was afraid that it would be completely ineffective.

But at this time, there is no need to care about this, so it is better to enter the second treasure house quickly.

When he stepped into the second treasure house, Han Xiao's eyes couldn't help but light up. I saw that on the opposite platform, there were five immortal swords suspended. At the very end, there is also a peculiar box.

Han Xiaoben's current sword-casting attainments can already be called a sword-casting master, so he naturally knows at a glance that these five "fairy swords" are not trivial. Although they were separated from themselves by a purple light mask, their determination actually penetrated the light mask and forced people to come. What's more, two of the fairy swords were still desperately calling for themselves, as if they wanted to take them away.

Among the five outstanding immortal swords, Han Xiao stopped his gaze on the obscure sword in the middle.

Just because it didn't have any breath, and even with Han Xiao's inductive power, he couldn't even feel its existence. He couldn't help but wonder in his heart, so he walked up to it.

Upon closer inspection, I saw that this thing was incomparably sharp, and the sword body was like a calm lake, and the sword light flickered and flickered, as if it would disappear at any time.

But with Han Xiao's spiritual power, he never sensed that it had half of its aura. But since it was an immortal sword that could be placed in the treasury of the gods, how could it be a mortal iron without any aura?

Any immortal sword is undoubtedly an aura that is compelling, even if it is an ordinary mortal iron, it also has a trace of sharpness. But this sword is an exception.

Silent, unfluctuating.

Han Xiao couldn't help but guess: Could it be that the sword qi emitted by this sword could slash at the enemy silently?

If this is the case, combined with his instantaneous killing sword intent, it is simply an existence against the sky!

It is conceivable that if you use it to assassinate others, how many people in the entire desolate world can escape? Even those Nirvana masters will not be able to detect the breath of this sword.

If it goes a step further, this sword can still conceal the aura of its master, then there is really no solution.

"Gollum. ”

Han Xiao looked at this silent immortal sword, and struggled in his heart, should he take a gamble and pocket this "silent sword"?

But Han Xiao hesitated in his heart, and looked down at the "Soul Refining Ding" in his hand again, thinking that the bone-eroding blood had already begun to thicken, and it seemed that there was only one last chance.

Do you want this lifeless sword?

Han Xiao was a little hesitant......

Take a gamble, get a silent sword, and kill silently and kill without interest. But it is also possible that it is unlucky, the effect of this sword is not as rebellious as he imagined, and the aura is far inferior to other fairy swords.

Or seek stability, any of the immortal swords in this are not ordinary, and they are all water-based immortal swords, which can just fill the vacancy of losing the Xinghan Sword.

Han Xiao frowned and thought for a long time, but he still didn't make up his mind, so he simply looked at the last treasure.

It was a huge sword case, with a delicate pattern carved on its surface, about six feet long, seven inches wide, and about three inches thick. Looking at its appearance, it is wide at the top and narrow at the bottom, and it resembles the shape of a sword. But it looks like it's not gold or wood, and I don't know what material it's made of.

But it is clear that this is a box where the sword is placed.

This kind of thing is very rare, because the swords of ordinary swordsmen correspond to the kind of very convenient scabbards, and there are even swordsmen who specialize in drawing swords, and only at the moment of drawing the sword, they burst out with an amazing murderous aura.

The scabbard is what the swordsman places his sword, but there is also a sword that can only be placed in the sword case.

That kind of sword is generally the most domineering and terrifying sword in the world. The scabbard can't hide the murderous aura of this sword, and only with a heavy sword box can it hide its edge.

And such a sword, once taken out, I am afraid it will be a disaster.

"Instead of having a hard time choosing among the five fairy swords, in contrast, this sword box makes people more imaginative. Han Xiao's palms were slightly sweaty, he had heard that there was once a sword that could only be contained in the sword box.

This sword is called Broken Army.

Breaking the army, as the name suggests, breaks the front army with one sword!

"Okay, just pick this sword box. Han Xiao took a deep breath and muttered to himself, "I hope you won't let me down." ”

He stared at the strange sword box, and finally picked out a drop of mixed bone-eating dragon blood and dripped it onto the seal prohibition outside.

Who knows, the protective shield didn't respond for a long time, until the bone-eroding dragon's blood slowly dried up, and it was still firmly covered by the outside of the sword box. Han Xiao was furious, and dripped another drop of bone-eroding blood. At this time, he felt a little regretful.

There is very little bone-eating blood, and it seems that it can only dissolve one item at most. However, now, Han Xiao has used it on a "box" that may not be of any use.

But at this moment, Han Xiao was also resolute, seeing that the two drops of "bone-eroding blood" only had a slight effect, he gritted his teeth and simply poured the last two drops of bone-eroding blood on them.

Thankfully, it worked out this time.

Four drops of bone-eroding blood finally carved out a small hole, Han Xiao smiled bitterly, lifted the Burning Silence Sword, and stabbed it into the small hole.

With a "pop", the light mask shattered. Han Xiao picked up the heavy sword box, only to feel that this sword box was extremely heavy, and with his current strength, he couldn't pick it up after holding it.

This kind of weight, I'm afraid that there will be at least 200,000 catties!

You must know that in the myths and legends of China, it is the Dinghai Divine Needle of the Monkey King, which is only 108,000 catties.

"I wiped it, I don't know what's in it, it's so heavy?" Han Xiao's heart couldn't help but get excited, "Is there really a peerless fierce sword hidden in here?"

With the last trace of anticipation, Han Xiao shook the heavy box, but he was disappointed, there was nothing in it at all!

"Damn, isn't it!" Han Xiao was dumbfounded, could it be that he had exhausted the last of the bone-eroding dragon blood in exchange for the box, was it really just a box?

Han Xiao clenched his fists, and his heart couldn't calm down for a long time, but in the end, he comforted himself: "It's a big deal, it's okay to pretend to be silent in the future!"

However, something happened that made Han Xiao even more desperate, this box was completely free of cracks and could not be opened at all!

Now it doesn't even have the function of a sword case, it's just an iron lump.
