In terms of Su Wen and Ellie's skills, this kind of stone wall of almost 90 degrees, as long as there is a place to stay, then the difficulty is the same as going down the stairs.

Even if there is no protrusion for you to settle on, it is not difficult to insert your hand into the stone wall that is not too hard to fix.

Descending into the cave, Ellie felt like she was home, climbing on the rock wall with one hand, jumping back and forth as if showing off her climbing skills.

Su Wen could even see the excitement in Ellie's eyes through the face armor.

"You calm down......"

"Yes, yes!"

Although she promised to do so, Ellie's behavior did not restrain in the slightest. Su Wen had never seen Ellie so excited, and seeing that there was no danger, he didn't remind him anymore.

The general method of measuring the depth of a pit is to throw a heavy object down to listen to the sound, and if it is well-equipped, the heavy object thrown down can still emit light.

Su Wen didn't have anything at hand, so he released a few flares to try to see as far as he could.

"Su Wen, look! there's something!"

Ellie's eyesight was much better than Su Wen's, and after Ellie said this, the two fell nearly a hundred meters before Su Wen discovered the thing Ellie was talking about - a cluster of white plants.

Judging from the appearance, Su Wen couldn't tell if it was an herb or some kind of fungus. However, in such a place where sunlight can't reach, there is such a thing, which can be regarded as a kind of spectacle.

Ellie reached out and broke off one of the "branches" of the plant, took it in her hand and looked at it, and then put it in her mouth.

Although this is not a nature reserve, Su Wen still has the resistance inherited from his own world for the destruction of the environment, and wants to stop it, but after thinking about it, forget it.

"Why are you eating this?"

"It's not poisonous, it's tasteless, it's like a normal mushroom. ”

So it's not herbs but fungi, but how did such a cluster of plants get here?

"And there's a lot more down there!" Ellie gestured down.

By the light of the flares, Su Wen really found that there were many mushrooms growing not far below, but apart from the mushrooms, the two of them didn't find anything else, such as insects or anything.

It stands to reason that insects should be the most widely distributed creatures. Whether it's at the bottom of the sea, or on the very high mountains, or in the dense forests, volcanoes, or even underground, you can find them.

But there doesn't seem to be such a thing in this hole, as if it were a special field that has been enclosed......

"It's getting hotter and hotter......"

Su Wen touched his forehead, and there seemed to be some signs of sweat.

"Oh, is it?" But for Ellie, the change in temperature was almost the equivalent of nothing: "You say, could this cave be some kind of monster's lair, or could it be some treasure left by an ancient god?"

Ellie's question seemed meaningless, but it reminded Su Wen of ordinary children.

Most of the parents have experienced that when they were raising children, they were asked by innocent children in the form of "Daddy, Daddy, Mom, Mom, why XXXXX?"

As people grow, this kind of sentence question will gradually disappear, but even adults, in some cases, will subconsciously ask similar questions.

Although the sentence structure may be different, the starting point of the essence of the problem is the same.

Psychological research has shown that the situation of asking such questions stems from the "instinctive human desire to learn", and secondly, it leads to communication with others in the form of asking questions.

"It's possible, but judging from the current situation, I think this should be a relic cave. ”

Su Wen thought of Shireen's stone statue, and closer, as well as the things Graham had left behind in the academy.

The speed at which the two of them fell was actually quite arbitrary. But if you change it to the perspective of ordinary people, it is almost the level of "flying".

Ordinary adventurers rarely risk their lives to go to such semi-enclosed spaces, unless the mission demands or the benefits are huge. Because this kind of enclosed space is the most dangerous, once there is an accident, it will give an account of its small life.

Therefore, when adventurers are about to go down the hole, they will be fully prepared, safety ropes, lighting, self-defense, heat preservation, climbing and other equipment will be brought, and the speed of landing is also one step at a time, which is quite slow.

But Su Wen and Ellie, as if they were strolling leisurely, jumped between the stone walls and kept falling.

"Look at the top of your head, there's only a small dot left......"

"yes, this hole is deep enough. ”

Su Wen's meteorite technique can capture the meteorites in the universe, and it is not difficult to deduce from this point that this world is essentially a planet, and if it continues to fall like this, what can be reached in the end is still the center of this planet.

The structure of the Earth's core, mantle, and crust has always been only a speculation by scientists, but this speculation is also based on a large number of scientific observations.

But even so, the center of the planet is still an unknown existence for Su Wen.

"Wait!"

Ellie suddenly stopped her movements and climbed onto the stone wall.

"What's wrong?" Su Wenyan, who was a little slower than Ellie, also stopped and looked at Ellie.

Ellie didn't look back, instead focusing on the depths of the cave.

"I smell monsters! a lot! It's a bit strong......"

The one that can make Ellie say "a little strong" is at least a monster above the diamond level, right?

But because of Ellie's speech disease, Su Wen didn't know for the time being, whether the monsters that emitted the smell were a little strong in total, or whether there were many monsters that were a little strong.

Let's hope it's the former...... If it's the latter, it's more troublesome......

"Shall I put away the flares, then?"

"Whatever you want, I want to go down and have a look anyway!"

"I think you'd better be careful......"

"Rest assured!"

Peace...... Su Wen still couldn't settle down for the time being.

If there are really monsters in the depths of the cave, then there is a reason for those monsters in the mountains to retreat, and the rumors that the merchants have seen and circulated are also true.

Like all creatures, the instinct of monsters is still to survive and reproduce. If they are too vigorous to reproduce, then they will expand their range of existence, thus threatening human society.

If it is not contained, then even a catastrophe is possible!

Su Wen had seen a lot of similar disasters in history! It's just that human beings, tenacious creatures, have survived every time at a great cost.

In the final analysis, the current peaceful life is also the accumulation of generations of human beings.

Thinking of this, Su Wen breathed a sigh of relief.

Fortunately, I was a little uneasy, so I came in advance to help the investigation team step on it...... Otherwise, the consequences will be troublesome......

Although this monster has nothing to do with Su Wen, it will not be good if it develops into a disaster and threatens Marina's snow castle.
