Professor Liu couldn't wait to crumple the map in his hand and throw it away, what kind of broken map? But reason made him suppress this impulse, at least, he couldn't do it now, as for the mysterious map he obtained, Professor Liu didn't count on it at all, that map was useless from the moment they entered the crater.

Professor Liu looked up and saw that it was a dense forest, and when he looked around, he saw trees in addition to trees.

"Watch your step! Go, go to the front and have a look!" Out of sensitivity to the bright light, Professor Liu decided to go straight and go to the front to have a look, because it looks a little brighter there, and the grass under his feet is very soft to step on, but he can't take it lightly, what if a snake comes out of it?

Continuing to go deeper, the trees became denser and denser, and there were no footprints left after walking on the grass, if it weren't for the confidence in the equipment, Professor Liu would never have been so supportive.

There was nothing to do along the way, but the deeper and deeper he went, just when Professor Liu wanted to give up, the changes in front of him gave people a feeling of suddenly opening up and seeing the moon through the clouds.

"Ahh

It can only be regarded as a narrow and long ditch, Professor Liu knows at a glance that it has not been short, at least more than a thousand years, and this ditch is suspected of being artificially made, the ditch is very long, like a moat in front of the ancient city gate, meandering and clearly dividing the dense forest into two parts, looking at the opposite side, Professor Liu estimated in his heart, unless there is something like a flying tiger claw, otherwise, don't look at the ditch is not wide, even if you are good, you can't jump over.

It's kind of weird. Professor Liu looked up at the sky, it was a little gloomy, it was a bit strange for this ditch to appear here, from any angle, there was no reason for a ditch to appear here.

The weather changes have become more and more irregular, and after two or three days here, Professor Liu found that the laws discovered back then are no longer applicable, and everything is out of the trajectory.

"Professor, this is what you're looking for? a ditch by yourself, it's nothing, do you want to go down and have a look?" Ye Chen came up and took a look, pouting, it's nothing.

"There are traces of water flowing through this ditch!" He Yuxi looked at it carefully, frowning, this ditch seems to be artificial, but it is too old to see anything, and, the most important point is that this ditch is like a dividing line, if the dense forest trees they are in are just too luxuriant, then the opposite side, which seems to be the same dense forest, gives people a sense of coldness.

Just looking at it makes people feel uncomfortable!

It seemed that there was a lot of articles in the dense forest opposite, He Yuxi retracted his gaze, and felt that the sky above was a little gloomy.

The ditch is not too deep, more than ten meters, it seems, maybe dozens of meters deep, because the ditch is not wide, the sun can't shine below, it is covered with moss, weeds, vines and the like, and there are a lot of protruding rocks.

Professor Liu couldn't make up his mind, could he go down and take a look? However, He Yuxi's words made him instantly decide, go down and take a look!

"Rope!" Professor Liu immediately started to act after making up his mind, patted Ye Chen on the shoulder, and asked him to take out the special rope in his backpack, the rope was very thick, made of several thin ropes, Professor Liu fixed one end to a tree that looked particularly thick, and tried hard to be strong before throwing the rope down.

"Hey, let me go down!" An archaeological team member volunteered to stand up, as the team leader, Professor Liu can't go down no matter what, who will be responsible if something happens? And He Yuxi and Ye Chen, in the eyes of the archaeological team member, are both newcomers, but they have a little experience.

He is the only one who is the most suitable to go down, because he is a mountaineer and is extremely familiar with this aspect.

"Okay!" Professor Liu tied another rope to a tree, nodded, and handed over both ropes to the archaeological team member, double insurance, so it was safer.

"Be careful!" Professor Liu instructed uneasily.

The archaeological team member nodded, did not speak, bit the flashlight in his mouth, and could not speak, and slid down the rope little by little, this is an adventure!

There was silence, and the team members who stayed up held their breath, staring at the rope on the one hand, and turning on the walkie-talkie on the other, ready to receive the message.

"Professor, I went down to fifteen meters, I didn't find it, everything is normal!"

"Professor, it's already twenty-five meters, I haven't found it, everything is normal for the time being!"

“……“

On the walkie-talkie, the report of the archaeological team member was heard from time to time.

"Professor, it's a little bad, I seem to hear the voice of a cry for help, do you want to keep going down, it's already very dark around, even if you use a flashlight, you can't see the situation below, but I feel like it's almost bottom!" After a long time, just when Professor Liu wondered if there was an accident, the voice of the archaeological team member came out of the walkie-talkie again.

The information that came out made the players above not very responsive.

A cry for help?

What kind of international jokes, let's not talk about what kind of place this is, the depth of the light ditch, not to mention people, even if the vitality of the super tenacious rat falls, it will become a pulp.

"This, are you sure it's a cry for help?" Professor Liu wants to confirm that if it is really a cry for help, in this kind of place, Professor Liu feels that this multiple-choice question is not ordinarily difficult.

"I'm not sure, but it sounds like there is, but I can't hear anything when I listen carefully!" After a while, the voice of the archaeological team member came out of the walkie-talkie again.

"That's right," Professor Liu pondered, "Go on, be careful, and notify me as soon as something is wrong!"

"Okay!" the other person's voice came over the intercom.

"Professor, I think it's necessary to tell you, the further down, the more lush the weeds grow, this phenomenon is not normal, there is no sunlight down all year round, there is no reason for these plants to grow so luxuriant!" After another difficult period of time, the voice of the archaeological team member came from the walkie-talkie again, with a little surprise.

Professor Liu silently said that everyone should be very clear about the things necessary for the growth of plants in nature, water, sunlight, nutrients, no plant can grow without sunlight, even plants such as mosses only like shade, not that they do not need sunlight to grow, even people who are long in all things also need to bask in the sun from time to time to stay healthy.

At this time, Professor Liu had already concluded that the weed was a plant that was almost extinct and had never appeared in the outside world, a plant that could grow without sunlight!
