A black tree stump appeared in front of my eyes, and I immediately pulled Sun Xiang up and said, "Old man, look, we are going over there." ”

"This can't be done, the stump I want must be able to see the annual rings, otherwise I can't determine the direction at all." Sun Xiang shook his head and frowned, although he was in a hurry, he couldn't do anything about looking at the black trunk.

"Then I'll interrupt it." With a bang, the one-foot-thick tree trunk was broken by me, and I breathed a sigh of relief when I saw the fractured position, the position of the trunk against the ground, only about ten centimeters outside was scorched, and the heart of the tree inside was still intact, it seems that the time from the eruption of magma to the cover of volcanic ash was very short, otherwise there would be no such situation.

Sun Xiang showed joy, leaned down in front of the tree stump and examined it carefully, and taught me how to identify the direction.

The growth of trees has the characteristics of phototaxis, generally speaking, the position of the south side of the light grows faster than the position of the backlight, and it is precisely because of this characteristic that there is a way to see the dense branches to distinguish the direction, but this place because of the trees, can only be determined by the stump.

The trunk, like the branches, also has phototaxis, and the direction of the light will grow faster, so the longer the tree, the center of the tree ring will shift to the north, and the growth ring will also show an elliptical shape, and the farthest direction from the center point of the growth ring is the south.

Although the annual rings of this tree stump are not clear, after many annual rings argue with each other, Sun Xiang quickly found the southeast direction and led us forward.

But soon we lost our way again, although we have been walking, some of the mountain bags are directly climbed over, but there are too many mountain bags in this place, a little offset at a time, and when we climb more than ten mountain bags, we no longer know where to shift.

I blasted open a few more mounds of earth, but I couldn't find a suitable stump, just when I was anxious, I suddenly felt a fresh breath, and then looked to the right, it was a small dirt hill more than thirty meters high, and there was a green plant more than a foot long fluttering in the wind on the top of the dirt mountain.

If there is a plant growing in such an environment, it proves that there must be water underneath the plant, and perhaps the Bangmao River is there.

Thinking of this, I hurried over, and when I climbed the little dirt mountain, I found that the plant was a small willow tree, although the tree was not high, but the small trunk was full of cracks, not like a seedling, but like an ancient tree that had been through the vicissitudes of life.

"Qin Ling, I seem to be much better." Liu Qianying squatted down and stared at the little willow tree curiously, her face had already recovered to be ruddy.

Perhaps it was the oxygen formed by the photosynthesis of the little willow tree that drove out the carbon monoxide, which made Liu Qianying have no poisoning reaction, not only Liu Qianying, but also Sun Xiang was much better.

"The carbonized wood in this place is constantly burning, and the entire ground has reached an extremely high temperature, and it is impossible for any animal or plant to survive here," Sun Xiang said with a deep sigh: "This little willow tree grows here, and it is likely that there is a lot of water underneath, which can not only supply it with the necessary water, but the most important thing is to reduce the temperature of the soil here." ”

"Boss, do you think it's possible that the Bangmao River is just under this little willow tree?"

Sun Xiang nodded, "This basin is very large, and it is a carbonized wood site, it is not easy to find a tree stump that has not burned through, and this Bangmao River suddenly disappeared after entering, even if we go to the edge of the basin, we may not be able to find the Bangmao River." ”

"Then we'll dig it up." I immediately decided, and a few people began to dig the earth.

This is thirty meters long to make the dirt mountain, and there are no digging tools, if it is an ordinary person, it will definitely not be able to dig it, but it is not too difficult for us, first Song Junhe stabbed the soil bag with an iron chain to loosen the soil, and then I threw out all the carbonized wood and big stones, and then the evil face corpse woman used the black magic crutch to smash the loose soil, Song Junhe can use the iron chain to pull the soil out from below, and at least three meters can be dug down each time.

It's just that in the process of excavation, we feel that it is getting hotter and hotter below, and what makes me strange is that there is not a trace of dampness around, and it stands to reason that if the Bangmao River is below, such a temperature will definitely accelerate the evaporation of the Bangmao River water, making the ground damp and full of moisture.

But we have almost dug for 30 meters, and the soil is still extremely dry, which is not at all reasonable.

Just when I was thinking in my heart, I saw Song Junhe's iron chain inserted into the soil again, but as soon as he pierced it, Song Junhe screamed, the iron chain was thrown out of his hand, he fell to the ground and trembled violently, his whole body spasmed, and his eyes rolled white.

I was shocked in my heart, although Song Junhe didn't make a move many times, but this guy's strength is definitely not weaker than the evil-faced corpse woman, otherwise the two of them would not cooperate, but Song Junhe was inexplicably made like this, and the things below must not be easy to deal with.

With Song Junhe's experience, I didn't dare to continue digging down, only waiting for Song Junhe to recover, and then walked up with the evil-faced corpse woman and asked, "Song Junhe, what happened just now?" ”

"There's electricity down there." Song Junhe said with palpitations: "And the current is very powerful. ”

Song Junhe stood up, layers of blood scabs fell from his body, and the injuries on his body that were scorched by electricity also recovered, but he didn't want to continue digging down with chains, and the evil-faced corpse woman saw Song Junhe's appearance, and her face was also a little hesitant.

I don't know if we should continue or not, if there is a strong current down there, we will probably be electrocuted if we don't have any protection, but if we don't continue, then we have no clue to get out.

"Old boss, you take Liu Qianying up first," in the end I decided to continue, although Song Junhe was electrocuted just now, there was no danger to his life, in order to be able to go out, I must try, otherwise in such an environment, Sun Xiang and Liu Qianying will soon be unable to persevere.

Sun Xiang also knew that he couldn't help, so he took Liu Qianying to walk up, but Liu Qianying didn't want to leave me at all, so she pushed Sun Xiang and rushed towards me, Sun Xiang was about to fall off guard, and grabbed the small willow tree with his hand, but he didn't expect that the trunk was not only not broken, but broke Sun Xiang's hand.

Blood flowed down the trunk of the little willow tree to the ground, but the ground suddenly trembled, and the earth under our feet could not bear our weight and all fell.
