Relieved his nerves, suppressed the excitement in his heart, Ding Yi didn't dare to go down rashly, there is not a single animal here, who knows if one foot will touch the mechanism or something, it's always right to be cautious.

After thinking about it, he took out a red rock bird corpse from the space and threw it to the ground, ten minutes later, the corpse did not change at all, and he took out another one and threw it into the black water of the lake with a little effort, who knew that as soon as the corpse touched the black water, it emitted a sizzling black smoke, and in less than a second, only a white bone remained, and the next second the white bone was slowly melted away.

Ding Yi swallowed her saliva secretly, if she guessed correctly, the reason why there are no animals around must have something to do with this lake water! The hand involuntarily touched the gas mask on his face, and he breathed a sigh of relief after confirming that it was still good on his face, I don't know if this air is also poisonous!

Regardless of whether it was poisonous or not, it was impossible for her to be tempted by watching so many gold-devouring vines, so without long hesitation, Ding Yi still slowly climbed down the cliff and entered this underground world.

Pick up a piece of dead branch to explore the way, and the entire underground world can only hear your own footsteps, quiet and eerie.

Ding Yi didn't dare to get too close to the Black Lake, only in a place far away from the lake, took out a pair of gloves from the space and put them on, probably turned around within a safe range, and found that the closer to the Black Lake, whether it was the gold-devouring vine or other plants, the vitality was stronger, and other plants directly reflected that they were more individual and thick than the peripheral plants, and the gold-eating vine was more and more excellent in color texture and fiber toughness.

Although I can't guess why this happened, it must have something to do with the water of the lake, but unfortunately Ding Yi didn't dare to risk getting too close to the black lake, so he could only choose to get as close as possible to start collecting the gold devouring vines and putting them into the space.

It wasn't until the space could no longer fit that Ding Yi finally collected a few seedlings of gold-devouring vines and other plants, and began to look carefully at the place, looking for any places to go out.

was walking around, suddenly from the black lake came a "coo" sound, although the sound is not loud, but in this quiet environment, no matter how small the sound can be heard, not to mention this "coo" is not small.

"Coo-dong, coo-dong" two more times.

Ding Yi had a faint bad premonition in her heart, but she didn't dare to get close to the black lake to see what was going on, so she could only find a big tree nearby and climb it up to look at it from afar.

I saw that the originally calm black water was boiling one after another, and the traces of the water that were originally somewhat overflowing were directly submerged, and the strongly corroded black water began to spread out, except for the big trees and gold-devouring vines that grew to a certain scale, and the other smaller plant seedlings withered and disappeared instantly as soon as they touched the black water.

This is not the most terrifying, the most terrifying thing is that as the bubbles that continue to emerge in the black water burst, wisps of black smoke visible to the naked eye slowly fill the air, this black smoke is obviously more powerful than the black water spreading on the ground, floating directly into the air, and the young plants that come into contact with it die even faster than the black water that comes into contact with it, and it is simply more unpreventable than the black water spreading on the ground!

Seeing this situation, Ding Yi didn't have time to think about the fear in his heart, jumped off the big tree directly in three or two, ran from the hole when he came and went, and ran in less than five minutes, and finally came to the cliff that came down, just about to climb the rock, but when he looked up, he found that he didn't know when the hole was emitting a burst of earthy yellow smoke, the smoke particles were obviously larger, and they slowly descended as soon as they came out of the hole. That location is just the farthest from the mouth of the cave and the Black Lake at the same time.

In ten minutes back and forth like this, the yellow smoke and black smoke have begun to spread to a third of the underground world, and in some places the two kinds of smoke collide together, making a sizzling sound of corrosive corrosion, Ding Yi didn't dare to look back, except for his own panting and footsteps, all of his ears were the sound of bubbles bursting and corrosive, and he prayed again and again in his heart that this strange phenomenon would end soon or let her find a way out!

The situation is becoming more and more critical, the smoke is getting bigger and bigger, and it seems that it is approaching Ding Yi's corner, and the nervousness and fear in Ding Yi's heart are getting stronger and stronger, but now no one can save her except herself, and she strongly suppresses the fear in her heart, and her eyes unconsciously look around, looking forward to finding some escape clues!

"What to do, what to do, do you really have to explain it here...... Damn the bird place, except for trees and trees, there is no ......" Thinking of this, Ding Yi slapped his head violently, stupid, tree!

He quickly found the largest tree with its branches sticking out of the ground, and climbed up in two strokes. I really have to thank the school for training them to climb trees in order to train them to climb trees in order to train them to get on the mecha, otherwise she wouldn't be so agile now!

I chose a higher branch and sat down, this height has a good view, just enough to see the general layout of the entire underground world, look around, and see that not only the hole when she came was emitting yellow smoke, but also several other similar holes, presumably those holes are also similar to the passage when she came, it seems that there is more than one route to reach this underground world!

The quality of the two types of smoke is relatively large, and it will not be at her current height for the time being, but seeing that although they are slow but also rising, Ding Yi's heart flashed with hidden worries, according to this momentum, sooner or later, the poisonous fog will fill the entire underground world, and then she will really be unable to fly!

Sure enough, half an hour later, the smoke had spread to two meters above the big tree where Ding Yi was.

Suppressing the growing panic in his heart, Ding Yi made a ruinous decision, and looked up at several holes in the top of the cave that had been broken by big trees...... It was the only way she could find an escape now, and no matter what she would encounter if she went up, it was at least better than waiting to die here!

Straightening the mask on his face and tucking the dagger into his boot, Tin began to continue climbing the tree.

Half an hour later, finally approaching the canopy, the higher you go, the fewer gold-devouring vines, when you reach the canopy, you can still see only the black gold-devouring vines, and even look up along the target hole, you can also see a few black gold-devouring vines wrapped around the branches and growing outward, it seems that among the various gold-devouring vines in this place, the black gold-devouring vines grow the best.

This thought flashed through Ding Yi's mind, and he didn't have time to think about it now, so he would get out of the house first. The branches are getting thinner and thinner, and some of the branches that have penetrated into the stone layer at the top of the cave are even only two fingers thick, and it is impossible to bear her weight, and the most important thing is that it is not known whether such branches can penetrate the stone layer, so for the sake of safety, she can only climb between the branches and choose, trying to find the thickest one.

This wasted her almost ten minutes, and the smoke below had begun to fill half the height of the tree, and Ding Yi did not dare to look at it again, and continued to climb up the selected branch.

The hole drilled by the branch is narrow and irregular, and the upper body is just squeezed in. was blocked by a complete boulder above, which made Ding Yi unable to get up or down for a while, and his entire chest began to hold his breath.

There was no choice but to retreat, take out a small shovel from the space and start shoveling the stones, fortunately, the stone itself was also very loose, and it fell from it in two clicks, making a dull landing sound, and a pile of sand and stones fell from the entrance of the cave, which just made the hole wider, and the light falling from the hole was a little brighter.

Ding Yi finally glanced back below, the smoke had obviously risen a little again, and the smoke obscured the situation below, but from the constant sound of corrosion coming from all directions, even the black water had spread to the entire underground world. Taking a deep breath, I climbed up to the top of the cave with all my might, and with the help of the winding branches and uneven walls, although the climb was difficult, it was getting closer and closer to the ground.

Half an hour later, Ding Yi finally put one hand out of the hole, closed his eyes, waited for his eyes to adapt to the slightly dazzling light, supported the ground with both hands, and jumped out of the hole, too late to look at the surrounding environment, only a general glance, to see that the surrounding trees were dark black, should be in the hinterland of the red and black forest, and found a random direction to run.

Who knows if the strange smoke will spread out along the hole, and to be on the safe side, the farther away the better!

After running without looking back for about ten minutes, Ding Yi stopped his pace and gasped for breath with a little relief, and was looking around to see which way to go, when suddenly, there was a heavy footstep in the distance!

This kind of footsteps, Ding Yi had only heard not long ago, it was the footsteps of a hand-controlled mecha! The difference was that this time it was obviously not a few path-finding mechas, and it sounded like there were at least a hundred.

Determining the approximate direction of the sound, Ding Yi decisively chose a different direction and ran again! Damn, there is no cave here for her to hide! It was found in the open air that she was not looking for death, shooting, one or two would still be hiding, if hundreds of mecha were ...... together Hehe, it's good to be able to keep a whole corpse!

Ten minutes later, Ding Yi stopped again, leaned against a big tree and kept panting, feeling less uncomfortable in his lungs for a while, and only then did he think of one thing, these black-clothed people were coming for the gold-devouring vine, and the direction of going was obviously the direction of the underground world, but now the underground world was spreading poisonous fog, and those people were not going to die now......

Thinking of this, a bright light flashed in Ding Yi's eyes! Without hesitation, he turned around and walked back, as long as the man in black came to the gold devouring vine, he would definitely go to the underground world, as long as she found a safe location that was not far away and not easy to be detected in advance, she would definitely have a great chance! In addition, this group of people in black was unlucky, and they just happened to encounter the time when the poisonous fog of the underground world was filled, which could just catch them off guard, and her chance of sneak attack was even greater!

The more she thought about it, the faster she walked, and in order not to be discovered halfway, she deliberately went around a long way before returning to the top of the underground world. After confirming the direction of the man in black, he chose a place five hundred meters away from the underground world and out of the range of mecha heat induction, and hid behind a boulder to hide his figure.
