Beneath the cliffs is a slender valley with a babbling river. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The river is not very wide, but the water is deep and the water is clear, and you can see a lot of fish living in the water through the water.

What made Song Zheng's eyes light up was that these fish were not ordinary fish, but biochemical fish!

Although most of them are biochemical beasts that are not even level 1, even so, it means a large amount of low-level evolution fluid.

If it weren't for the fact that he was still very unfamiliar with the environment and had concerns, Song Zheng almost couldn't help but run to the river and start killing fish.

Above the valley was clouds and mist, which should have completely blocked out the sun, making the valley pitch black.

But I don't know why, not only is it not dark around, but it is even very bright, except that you can't see the sun, and the brightness is almost the same as the outside.

In addition to this, which Song Zheng couldn't guess, what he was more worried about was actually his mental power perception, which had been compressed to the limit after arriving here.

Originally, in the clouds and mist, it was compressed by an unknown force and only had a perception range of a hundred meters, and after reaching the valley, it could not even maintain twenty meters.

On it, it is the eye that cannot see, and the perception can still be used. Below, it's the other way around, the eye can see, but perception can't be used.

Without perception, Song Zheng was very uncomfortable, and he always felt panicked psychologically.

This is one of the reasons why he didn't run to the river to kill fish in the first place.

Just when Song Zheng was thinking about what to do next, there was a huge change in the valley that shocked him.

Countless halos of colorful light suddenly appeared around the valley, and these halos were generated, spread like water, and then converged towards one place.

It was a cave.

Halo after halo, a total of three halos, all entered the cave!

Just when Song Zheng wanted to walk over and take a look, a pillar of light suddenly erupted from the cave!

After the pillar of light erupted from the hole, it did not crash into the opposite mountain wall in a straight line, but made a sharp ninety-degree turn and flew straight into the sky.

"It's the one!"

Song Zheng exclaimed.

The pillar of light he had seen before was actually formed in this way!

The shock quickly passed, and Song Zheng realized a problem, the formation of the pillar of light must be related to that cave, maybe there are some precious treasures in the cave!

Thinking of this, his eyes lit up, he lightened his steps, and quietly leaned in the direction of the cave.

The cave was on the other side of the river, and Song Zheng easily swung over the river with the help of vines and spiritual power tentacles.

Even when he was flying over the river, many biochemical fish jumped up and wanted to bite him, but they all smashed him back with iron pots.

Although he couldn't use all his strength in the air, he could only stun the biochemical fish, but he couldn't kill them, so naturally there was no evolution liquid in the account.

However, Song Zheng's attention was all on the cave, and he didn't care about the evolution fluid on the biochemical fish. The idiot also knew that if there was a treasure in the cave, it would definitely be a treasure that was many times more precious than the evolution liquid.

Approaching the entrance of the cave, Song Zheng suddenly felt a little apprehensive, after his spiritual perception could not be used, he could no longer detect what was going on inside the cave.

Without such an important investigative method, it is actually normal for him to be apprehensive.

Song Zheng doesn't just use mental perception. He hadn't forgotten some primitive reconnaissance methods.

So he lay on the stone wall on the side of the cave entrance, his ears pressed against the stone, hoping to hear the movement coming from inside the cave.

Lying there and listening for ten minutes, Song Zheng didn't hear anything.

There was no movement in the cave.

Frowning, he also knew that there was no other way but to try his luck.

So he held the iron pot as a shield in one hand and the dragon bone sword in the other, and walked slowly and cautiously towards the cave.

I had just walked into the cave, and before I could take a few steps, I kicked something under my feet, making a clattering sound.

Song Zheng was so frightened that he jumped three feet high, hurriedly ran out, ran a hundred meters outside the cave, turned around and saw that there was nothing to chase out, and then walked back cautiously.

Entering the hole again, he finally found what he had just kicked, which was a skeleton.

Song Zheng hurriedly squatted down to take a closer look, and recognized that this was a zombie skeleton!

And it's not an ordinary zombie, at least a first-level mutant zombie.

He saw the energy core of the zombie, its claws, even if only the skeleton remained, its claws still looked very sharp.

Of course, the energy in it has almost dissipated, and it can be distinguished as the energy core, but it has no value taken away as a weapon or forging a weapon.

Song Zheng shook his head: "Whoever killed this zombie is really a loser!"

The energy core is a good thing, even if it is not easy to use as a weapon, it can be sold to the base city, and it is also good to exchange some food and drink.

It's too much of a loser to throw it here.

Regret was only for a moment, Song Zheng concentrated again and walked towards the cave.

However, after not taking a few steps, he found a skeleton again, this time not from a mutated zombie, but from a cyborg beast.

It was a first-class mutant biochemical dog, huge in size, with a skeleton that was about to catch up with a male lion, and its four thick and sharp teeth were comparable to those of a saber-toothed tiger, just like the claws of mutant zombies, and there was not much energy left.

This time, Song Zheng didn't regret it, because he had already sensed that something was wrong.

His steps quickened slightly, and soon he found the skeleton of the mutant creature again.

"Sure enough, it's all the skeletons of mutated creatures, something must have happened!Could it be that the pillar of light?" Song Zheng muttered to himself, his steps speeding up again, and he no longer carefully examined the skeletons he encountered.

It was a wise decision, as the deeper he went into the cave, the more skeletons he encountered, and finally after passing through a long tunnel full of skeletons, he finally reached the center of the cave.

A wide and flat cave.

He suspected that this was already the innermost part of the cave, because the surrounding walls were smooth except for the passage behind him, and there were no extra caves or tunnels.

It's just that Song Zheng's gaze only swept over the terrain of the cave, and he was attracted by the thing in the center of the cave.

There was a huge stone ball, oval on the ground, five meters high, more than three meters at its widest point, and one meter at its narrowest point.

From a distance, it looks like a huge egg, standing on the ground!

And this huge egg-shaped stone ball is covered with a layer of colorful light, constantly exuding spirituality!

"Spirit Stone!" In Song Zheng's mind, these two words suddenly appeared, as if this stone ball was born with a name.
