......

Ying Zheng and the fat man walked slowly in the heavy valley, which was very deep, sandwiched between two mountains, very high and narrow, and there was only a concrete road in the valley leading to the darkness ahead.

A cloud of green smoke hung over the two of them, seemingly ready to descend at any moment, usually filling the valley almost uninhabited, but sometimes rising for a while, revealing a dilapidated concrete pavement, and then descending again.

The survivors who had broken into the valley had fallen on the pavement, their faces stiff, their bodies rotting, and they had been dead for days, and some of their bodies were only bones.

"Ah Zheng, it's pretty evil here." The fat man said as he looked at the crows with three pairs of blood-red eyes on the branches in the distance.

"Well, it's too quiet, let's get through as soon as possible." With that, the two quickened their pace.

The road of the heavy valley is not short, because it is sandwiched between the two mountains, passing through the heavy valley is equivalent to crossing the heavy mountain, and there is no half an hour to walk out at all, the two of them walk in the quiet valley, the green mist hovers overhead, and it is extremely mad.

After walking for a while, the two suddenly stopped, because the number of corpses in front of them suddenly increased, and one by one the well-armed survivors fell to the ground in front of them, and in the distance, a green mist lingered, blocking their way.

Ying Zheng carefully observed and judged: "These are two groups of survivors, they came here for a purpose and don't know what to do, because there should be an infighting, it seems that Du Huanyu is hiding a lot of things from us." ”

"What can we do, the road ahead is blocked by green fog, we can only go back?" The fat man asked tentatively, after all, all this seemed a little weird in front of him, and Du Huanyu must have hidden something very important from them.

"I guess we don't have that chance." Ying Zheng said lightly, "Look at the fog on your head. ”

When the fat man heard this, he looked up, and the fog above the two of them fell at a speed visible to the naked eye, and he estimated that there were still three or four minutes before they would be deep in the green mist, and then there would be two more corpses in this heavy valley.

"What! Du Huanyu lied to us, didn't he say that there was still an hour? At most, ten minutes passed. The fat man exclaimed.

"He should have plotted against us a long time ago, I really can't think of what his motives are, it's useless to talk about it now, I can't go back, let's find some other way out."

After that, the two of them began to look around for other roads, except for the cement road, there were only deep bushes and steep mountain walls on both sides of the valley, no wonder there were few traces in the valley, and there were many ghosts in the existence of this poisonous mist.

The two of them searched around for a long time but did not find any way out, only to see that the poisonous mist above their heads was getting lower and lower, and it would soon fall to the top of their heads.

Suddenly, Ying Zheng had an idea, and hurriedly asked the fat man, "Did you see any creatures on the road?" ”

"Creatures? Does a crow count? ”

Ying Zheng hurriedly grabbed the fat man: "Take me to the place where you saw the crow." ”

The fat man didn't hesitate when he heard this, and immediately took Ying Zheng to the place where he saw the crow just now, and it was not far away, according to the descending speed of the poisonous mist, it was still too late.

The two of them soon reached the foot of the dead tree, where the six-eyed blood raven was about to take off, and when they saw them hurrying up, they fluttered their wings and ran into the dark bushes.

"Keep up." Ying Zheng hurriedly reminded, and then a cat body, burrowed into the bushes, the fat man didn't know what medicine was sold in Ying Zheng's gourd, so he had to keep up, anyway, there was no other way now.

The two of them were behind the crow, the green mist getting lower and lower, and the crow flew very low, and after passing through the dim bushes, the blood crow disappeared directly into a hole more than half a man's height in the cliff.

"That's it." Ying Zheng said as he looked at the hole under the cliff.

He didn't explain anything, and went straight into the hole, because the green mist was getting lower and lower, and the fat man had to follow it when he saw this, and it took a lot of effort to get into the hole.

"Fatty, fire fold."

When the fat man heard this, he hurriedly took out two fire folds from his bag and lit the underground cave illuminated by the faint firelight.

The fat man looked back at the entrance of the cave he had just entered, the outside of the cave was green, obviously the heavy valley had been shrouded in green mist, but for some reason, the green poisonous mist did not pour into the cave, causing the two of them to escape.

"It's a matter of air pressure." Ying Zheng seemed to see through the fat man's doubts, "The air pressure in the cave is different from the outside world, so the green mist can't enter, and this hole is a headwind outlet." ”

Ying Zheng looked at the erratic fire fold and said, "Headwind, the green mist is even more unlikely to come in." ”

The fat man was still a little confused, after all, he was still dead just now, and in the blink of an eye, they left the shrouded range of the green mist, which was really a bit magical.

"That's... How do you know there's a hole here? The fat man asked, he hadn't reacted yet.

"It's not that I know, but the blood crow knows that there is almost no trace of life in the valley, and those creatures are estimated to not survive in the green mist, isn't it very strange that the crow you saw?" Ying Zheng said slowly.

"Either it's immune to green fog on its own, but it's a little less likely, as it's unlikely that only one blood raven in the valley is immune to green mist. Either it has a way out of the valley, or a way to avoid the green mist, so that it can rely on the green mist to kill the survivors, and then wait for the green mist to rise and come out to eat the corpses of the survivors. ”

The fat man nodded again and again, and naturally admired Ying Zheng, but he was still shocked by Ying Zheng's calm analysis between life and death.

"What if we don't find the Blood Crow, or if the Blood Crow just flies away." The fat man asked unrelentingly.

"Then I'll have to wait until I die." Ying Zheng said coldly, "This time I just escaped by luck, because I just saw the blood crow flying away, you can follow it, if not, then you have to wait for death, so... Du Huanyu: He is dead. ”

The clay man also has three points of anger, not to mention that Ying Zheng and Du Huanyu have no interest disputes at all, Du Huanyu still wants to frame Ying Zheng, and he almost succeeded, although the incident happened in just three or four minutes, but the thrill of this can only be experienced by Ying Zheng.

After all, if one wrong step is the difference between life and death.

"Now find a way to go first, and when we get out, Du Huanyu will be dead." Ying Zhengsen said coldly.

With that, the two looked around for a way out.
