The rat king stopped next to the holes and roared at the gerbils behind it. The gerbils immediately crawled into the holes.
No one knew how big the holes were. It was like a bottomless pit. No matter how many gerbils crawled in, there was still no response.
"I can't crawl into a hole like this." Jing Jiwu looked at the fist-sized holes and shook his head.
Xu Mi said, "How about we dig the holes and see what's inside?"
Jing Jiwu shook his head and said, "If we could, the rat king wouldn't stay outside. It's much better at digging holes than we are."
Xu Mi thought about it and agreed. If they could dig down, the super rat king wouldn't just stand there and not go in.
The gerbils were still crawling into the holes. Lin Feng looked at the rat king and said, "Do you think the rat king evolved to super because of the things inside the holes?"
Jing Jiwu's eyes also brightened. "If that's the case, then it brought its offspring here so that they could evolve as well. That is to say, there might be treasures down there that can help it evolve."
"Yes, that must be the case. Let's try and see if we can dig a hole." Xu Mi suddenly became excited.
"No need for that. You guys can all get on Little Star's back." Han Sen jumped on Little Star's back and said to Xu Mi and the others.
Although Lin Feng and Jing Jiwu didn't know what Little Star's ability was, they guessed that it might be good at digging holes.
Everyone jumped onto Little Star's back. Little Star's body was shining with starlight. It wrapped up the entire body and everyone. Then, Little Star went into the sand hole.
Lin Feng and Jing Jiwu originally thought that Little Star had the ability to dig holes. However, they were shocked to find that Little Star went through the layers of sand like it could go through walls.
"The ability to go through matter?" Lin Feng looked at Little Star in surprise.
Han Sen nodded. Hearing Han Sen's confirmation, Lin Feng and Jing Jiwu were even more surprised. This ability was extremely rare and powerful.
From how Han Sen killed Blood Bone Demon, to how Little Silver could detoxify and heal, to how Little Star could travel through matter, Lin Feng and Jing Jiwu couldn't help but marvel.
"Han Sen, you are God's favorite. You take all the good stuff. How are we going to survive?" said Jing Jiwu with a smile.
Han Sen smiled and said, "There are many good things in the shelter. I was just lucky."
Lin Feng and Jing Jiwu both smiled bitterly. If that was just luck, they really didn't know what was good luck.
The sand cave was very deep. After a few thousand meters, the small sand caves converged together, forming a huge underground rock tunnel.
Han Sen saw that the fluorescent river was flowing forward in the tunnel, and the gerbils were chasing after it.
Because the rat king didn't come in with them, only the ordinary gerbils were following the river. Many of the ordinary gerbils couldn't keep up with the speed of the river, but they kept running forward. They kept running until their mouths were foaming and their limbs were twitching.
Unfortunately, it was impossible for them to catch up with the river. Han Sen saw more and more gerbils falling behind, but he couldn't care less. He sped up and caught up with the river.
The tunnel was like a spider's web, and the river didn't leave any trace behind. If they didn't keep following it, they would definitely get lost in the tunnel.
Han Sen and the others followed the underground river for more than forty hours, and they saw more and more gerbils falling behind. Less than one percent of them were able to keep up.
However, even one percent was still a shocking number. There were at least ten thousand of them. Most of them were mutant gerbils, and a few were primitive ones.
To be able to follow until now, they were already somewhat exhausted. Many of the primitive gerbils were almost unable to run anymore. They were foaming at the mouth.
At that moment, the river in front of them suddenly stopped. Han Sen and the others stopped, too. They didn't rush to catch up.
The tunnel in front of them was even wider, forming a huge underground space. The fluorescent river flowed into the cave, forming an underground lake.
Han Sen and the others followed the gerbils to the lake. They suddenly saw that in the center of the lake, there was a small island. On the island, there was a tree with pear-like fruits.
"There is good stuff. We didn't make a mistake." Xu Mi was overjoyed. He wanted to fly across the lake to the island.
Han Sen grabbed Xu Mi, shook his head, and said, "Let's take a look first. If it is really a treasure, it can't be taken away so easily."
After a while, the gerbils had already rushed into the lake and swam toward the island. It seemed that they wanted to eat the fruits.
A large number of gerbils poured into the lake, but nothing happened. When the gerbils were about to swim halfway, they suddenly seemed to be pulled by something underwater. One by one, the gerbils suddenly sank, and in the blink of an eye, they disappeared into the Fluorescent Lake.
Han Sen and the others looked serious. They had been watching for a while, but they still couldn't figure out what had pulled the gerbil down.
Although the lake was bright, it was not very clear. Because of the brightness, it was difficult to see what was inside.
The gerbils kept sinking, as if they were being pulled down by a water ghost.
However, the group of gerbils did not give up. They still swam toward the island in the middle of the lake regardless of their lives. Many gerbils were pulled down, but a few lucky ones were slowly approaching the island.
"Not all the gerbils are sinking. It shouldn't be a problem with the lake. There is something in there," said Jing Jiwu, looking at the lake.
"It should be fine for us to fly over, right?" said Xu Mi.
"We can try, but everyone should be careful." Han Sen nodded.
Seeing that some gerbils were about to reach the island in the middle of the lake, they no longer hesitated. At the same time, they soared into the air and tried to fly as high as possible toward the island in the middle of the lake.
At first, Han Sen didn't feel anything, but when he was halfway there, he suddenly felt a force pulling him down into the lake.
But when he looked down, he couldn't see anything. There was nothing down there, so he couldn't do anything.
Plop!
Plop!
Han Sen summoned his God geno core and bloodthirsty ant king beast soul to stop himself from falling. However, he saw that Dragon Lady, Xu Mi, Lin Feng, and Jing Jiwu had all fallen into the lake and were sinking quickly.
