Seeing that the fire was getting bigger and bigger, and the jars stacked with protein oil were about to be affected by the fire, Du Yuqi looked around and found that the corridor on his right did not seem to have the existence of black mist.

Probably found out that Du Yuqi was far away from the escape, and the surging black mist seemed to be crazy, directly ignoring the restraint and damage of the flames to himself, and surging up, one by one, half-body ghosts pounced on the flames, turning into black mist and dissipating, and the originally surging flames actually dimmed, and a large amount of black mist was also directly pressed, and the originally burning fire belt was also forcibly suppressed to a height of less than half a meter, seeing that the black fog was about to chase Du Yuqi into the right corridor.

It's just that at this time, the faint blue flame that spread along the oil stains next to it has already scurried into the egg white oil jar pile next to it like a spiritual snake!!

Then, there was a bang!!

Under the dazzling flash and high-heat flames, the big bang happened instantly! Hundreds of millions of scarlet sparks were raised, and the blazing air waves suddenly swept wildly, rolling up a large amount of rubble, and when the big bang was generated, the black mist also emitted a terrifying and desperate roar!

However, there are still wisps of black mist in the corners of the third layer of the laboratory, the gutters, the exhaust holes, etc., and it is obvious that this terrible mysterious black fog has only been temporarily dispersed by heavy damage, and has not been eradicated at all.

About five minutes or so, in the light of the residual fire, a fallen broken door next to it moved, and then it was lifted, and then Du Yuqi crawled out from below, he was prepared to escape, of course, he could predict the time of the explosion, so he took precautions and protection measures in advance.

Of course, the defensive power of the set of inheritance plate armor on Du Yuqi's body is also not to be underestimated, if there is no this set of inheritance plate armor, the damage he will receive will at least be more than doubled, seeing that the rear is still burning, Du Yuqi stood up with grinned teeth and beat his waist a few times, and then walked towards the end of the passage.

At the end of the passage, Du Yuqi found some documents, although they were messy and rotten, but they also let him know the origin of these black mist, which actually came from the ghost train! The laboratory director here thought that he could control the power in it, and combine the ghost with the biochemical machinery to produce a tireless and painful terrifying weapon.

However, his attempt obviously failed in the end, and a large amount of evil spirit aura began to get out of control, gathering into a collection called sub-giant spirits, and then emanating from the ghost orb, diffusing everywhere, and even began to manipulate any human beings who came into contact, these evil spirit breaths appeared strongly mutated, scattered in any dark corner, and even absorbed the negative emotions of human beings, so they could not be eliminated at all, and finally led to the complete collapse of this laboratory!

After seeing this experimental material, Du Yuqi also sighed, the pursuit of strength finally led to the evil result of this distortion, which is also self-inflicted! The key is that he also suffered from the disaster of innocent pond fish, which is too depressing.

At this time, he carefully checked the structural diagram on the wall next to him, but was pleasantly surprised to find one thing, that is, there is actually a fast passage in the third floor that can lead to the second floor, but this fast passage is vertical, and the use is also very simple, that is, the slide for throwing corpses, and the test subjects who were killed in the laboratory on the second floor will be thrown down directly from this slide, and then directly enter the crematorium next to them after a transfer.

At this time, there is no doubt that it is almost impossible for Du Yuqi to return the same way, because it can be seen through the churning flames, and the wisps of black gas have begun to concentrate again, and he is now returning the same way that is to deliver to the door, so it is most convenient and fast to simply climb up from the corpse throwing slide.

As soon as he thought of this, Du Yuqi immediately took action, and without even dealing with the injuries on his body, he ran away at the location of the slide, at this time he did not enter the battle, his mood relaxed a little, and he found that the buzz he heard below seemed to be more intense, and this buzz should be not far ahead.

After Du Yuqi turned around the passage next to him, he suddenly noticed one thing, the ground of several rooms in front of him had collapsed, and there was a situation like a subsidence, at least a place the size of a basketball court directly formed a black hole, as if a huge mouth was unusually clear!

Damn, what's going on?

Du Yuqi found that the buzzing sound was coming from the ground depression, and carefully walked a few steps forward to look down, and suddenly found that hundreds of meters below, there was a blood-red mist permeated, and there seemed to be a blood-red giant mysterious object in the mist, which was twitching irregularly, and there were dense chain-like things hovering around the mysterious giant thing, and the buzzing sound was made by these chain-like things.

Suddenly, the giant mysterious thing swelled violently, and its volume swelled to twice its original size in an instant, and the chain-like things hovering around it immediately broke a lot, Du Yuqi immediately felt unstable on his feet, the ground was shaking, and the sand and debris above also fell with it, completely forming a small earthquake.

At this time, Du Yuqi was standing on the edge of the subsidence, and was shaken by the sudden shock, and he was about to fall down------ falling from a height of hundreds of meters, even his strength at this time was stable and he suffered a severe concussion and fractured his whole body, which had to be lucky.

Thanks to Du Yuqi's left hand, he violently pulled the broken floor next to him, and with the momentum of this buffer, he slammed the Cracking Soul Blade into the soil next to him, which can be regarded as stabilizing his body, and he has already fallen five or six meters away, which shocked him into a cold sweat.

Then Du Yuqi swung back to the ground, but before he could take a breath, he heard a strange voice coming from behind him, and when he looked back, he suddenly felt a little weak, because of the ghostly black mist "sub-giant spirit" I don't know when, it has been re-condensed and formed to chase after him, although there are only two or three double-knife resentful spirits at this time, and they still look very weak, but Du Yuqi knows one thing very well, that is, once he is entangled, then the enemy will become stronger and stronger, and it is estimated that it will be difficult for him to leave.

At this time, Du Yuqi couldn't care about the mysterious thing under the crack, and jumped up high after a run, and then grabbed a headlamp swaying on the ceiling with both hands, and then used this as a force to swing hard, and the whole person flew out in front of him, and then grabbed another headlight with both hands again and tried to swing out.

But at this time, the chandelier that was grabbed by Du Yuqi couldn't bear his weight, and it collapsed half of it with a click, and the dust and dirt on it immediately poured down, and then Du Yuqi's face was all over his face, not only that, but his safety at this time was completely tied to a short chain, and the chain was still creaking at this time, and it could be broken again at any time.

Fortunately, Du Yuqi had already planned before jumping out, and with a wave of his right hand, the whole person had already swung a zipline in mid-air, hung another chandelier on the top of the ceiling, and then swallowed his strength and swung over.

This zipline was purchased by him in an outdoor store on the earth, and it was specially used for those enthusiasts who climbed the snow peak, and there was an obvious claw hook at the end, which could accurately jam the ice cracks, and the boss even claimed that this rope could bear a weight of twenty tons, Du Yuqi estimated that the water contained in the words was used to squeeze, and the weight of five tons was no problem, so he simply bought it.

At this time, it seems that the quality of this zipline is really reliable, Du Yuqi's own weight plus that set of inheritance plate armor is at least one hundred and fifty kilograms, and this finger-thick zipline can withstand it steadily, and he didn't even tremble, and it was not in vain that he spent thousands of yuan at that time.

Then he went to the opposite room with a disgraced face, and when he looked back, the black mist behind him was actually chasing after him, but the black mist was very slow when it drifted through the huge pit.
