There were four thick snakes in the river, and when the four beads gathered together, they not only roared, but also emitted a powerful light that caused plants and animals to emit lightning-like waves of light wherever they went.

The plants are the roots, the animals are the snakes, and the three of them also emit light.

Those four light beads are ordinary a generator, continuously delivering energy.

Oni had studied chemical biology medicine a long time ago, and gave a reasonable explanation: the four light spheres emitted an electromagnetic field, which interacted with the magnetic field of the organism, and this reaction caused a photoelectric effect.

However, the fact that organisms are made to emit light without harming them, and that organisms are faced with countless different individual differences, cannot be attributed to the level of technology, because human technology has not yet reached such a powerful level.

Oni didn't understand how they did it, maybe it was just a coincidence, but if this situation could be a coincidence, then this coincidence would be too unscientific.

"Uncle, what should we do?"

Xiao Ying!

Oni Jiu looked back sharply, and Xiao Ying was standing behind alive.

"Xiaoying, where did you go just now?" Xiaoxue asked in surprise.

Xiao Ying looked at Xiao Xue suspiciously: "I've been behind you, I haven't left half a step"

Ghost Jiu looked at Xiao Ying again, there is nothing wrong with it, it's really weird, can this hole make people invisible? However, this also makes a bit of a mistake, because Xiaoxue and himself are not invisible.

In any case, it is always a good thing for Xiao Ying to come back, and as for the incomprehensible places, I can only put them aside for the time being.

The three of them didn't take any action because they really didn't know what to do. The best way to do this is to wait and see what happens.

The intense light lasted for more than ten minutes, and then gradually weakened, and then the four thick snakes slowly disappeared into the underground river, and the entire underground space returned to darkness, silent, and frighteningly quiet.

Suddenly, there was a swishing sound in front of him, and Onijiu could hear it, it was the sound of a snake crawling. Immediately afterwards, the sound suddenly intensified, like an ordinary rainstorm, and the sound went far ahead.

The flashlight in Xiaoxue's hand turned on again, and Onijiu suddenly saw the delicacy in front of him, not with the help of the light of the flashlight.

Onihisa's Celestial Eyes have been restored again.

"Hurry up" Oni Jiu said and quickly chased in the direction of the snake crawling, and the two girls did not dare to slack off and followed closely.

There was no tree root network in front of them, and because there were no obstacles, the three of them walked much faster. With hearing beyond ordinary people, Onijiu followed the direction where the snakes went, and after about ten minutes, a slope appeared in front of him, slowly rising. After walking for a few more minutes, a fork in the road appeared, and Onihisa listened to the two roads, and made sure that the movement of the snakes was in the branch hole on the right, so he took the two girls and turned in.

After walking for more than ten minutes, another fork in the road appeared in front of him, and Onijiu also relied on his hearing to choose the entrance to the cave. In this way, he encountered more than a dozen forks along the way, and the ghost followed them one by one and followed the snake's tracks.

After three hours of walking around the underground cave, there was nothing when the ghost arrived, but the two girls were exhausted.

"Master, no, I really can't walk"

"Yes, uncle, I can't hold on"

Of course, Onihisa knew very well that he could not stop at this time, and if he stopped, he might be trapped under this mountain forever, it was simply a labyrinth, and without snakes to lead the way, Onihisa thought that there was no way to find the right way out.

In the process of traveling, Onehisa found that there were many traces of human activity in this underground space, and even Onehisa saw a few stone balls, which were definitely not naturally formed, but what this stone ball was used for, Onejiu really couldn't see it.

"If you two hold on for a while, it may be coming to an end, Xiaoying, your sister's life and death are still uncertain, waiting for you to get something and go back to save her; Xiaoxue, maybe your brother is on the ground where we went out, you have traveled thousands of miles, isn't it just for your brother! "Oni Jiu didn't want to mention their pain points, but at this time, he could only use these words to stimulate them, otherwise the consequences would be even more unimaginable.

When the two girls heard Onijiu say this, they both gritted their teeth, stopped talking, and tried their best to keep up with Onijiu.

Human potential is definitely something that cannot be ignored, especially the love for relatives in the heart, which supports people's beliefs.

Isn't the persistence of the ghost long these days also because of the support of that love!

After two more selections of the entrance to the cave, a ray of sunlight appeared in front of the three people, and the sunlight shone into the cave from above, so warm, so warm, so kind, the two girls seemed to have regained their lives, and they shouted excitedly.

Onijiu can understand their feelings, and this is how he first saw the sky under the Jingdong Grand Canyon.

What people take for granted, when you lose it one day, you will realize how superficial the praise for it usually is, "beautiful", "precious", "wonderful", "lovely...... These words are superfluous at this time, and they cannot express their meaning, because it is your life, your breath, your pulse.

The top is very high from the ground, but unlike when you came in before, it has a funnel shape that is wide at the top and narrow at the bottom, and the slope is a little steep, but you can still climb it.

Onihisa looked around, listened carefully, and made sure that there were no strange creatures nearby, so he told the two girls to wait below, and began to climb up by himself.

This place is about forty meters away from the upper entrance, and when the ghost is halfway up, he finds that there are several side holes that go deep into the cave wall, and when he looks inside, there is a curvature inside, and he can't see very deep.

Onihisa was going to go in and have a look, but for the safety of the two girls, he still dismissed the idea. However, Oniku discovered a phenomenon, the stones at the entrances of these side caves were very smooth, and it seemed that it was caused by long-term friction.

Didn't the snakes climb up, but into these side holes? What are they doing in here?

Oniku wanted to know, because the behavior of these snakes was too weird, there must be some secret hidden in it, maybe this secret would allow him to learn more about the things that subverted the worldview, and those might help the truth he was looking for.

Oniku decided to get the two girls up first, and then come down to find out what was going on himself.

He took out the rope from his pocket and went down, and Onehisa shook his arm and pointed to his waist, motioning for them to tie the rope on. Xiaoxue tied the rope to Xiao Ying, checked it again, and waved her hand to Oni Jiu after making sure it was safe, Ghost Jiu pulled up hard, Xiao Ying had just rested below for a while, and had already walked a little strength, and climbed up with the pull of Oni Jiu. Then Onijiu gave the rope to Xiaoxue again, and Xiaoxue came up without much effort.

"You wait here for me, don't make a sound," he said, and the ghost crawled up again.
