Half a minute later, it was successfully refined.

"Where are you from?" Ling Yu said directly.

The crocodile was surprised by Ling Yu's appearance, perhaps because it had lived here for too long and had never seen a human, so it was very strange to Ling Yu.

However, it knew in its consciousness that it had to listen to Ling Yu, and Ling Yu was his master.

"Master, I've lived here since I was a child, oh no, I didn't live here before, it seems to have fallen from somewhere."

"Where did it fall? Do you remember? Ling Yu hurriedly asked, the place where he fell was not a river, so it was impossible for the crocodile to come from there, that is to say, there was at least another entrance here besides the entrance where he entered!

Unfortunately, to his disappointment, the crocodile forgot about it.

"Master, I don't know how long it's been since this happened, and I don't know where I came from, it's a big place, and my range of activities is limited, and I haven't come back to where I came here after so long."

Ling Yu sighed helplessly, looking at the size of the crocodile, it is so big, it is estimated that it has lived for decades, decades, let alone a crocodile, even a human, and basically forgot about it.

What's more, crocodiles didn't know anything at the beginning, and their IQ was so low, as long as they could live somewhere, they didn't care if they could go out if they came here.

Maybe it wanted to get out later, but unfortunately it couldn't find its way.

"Okay, I'll call you a crocodile from now on." Ling Yu gave it a name, "By the way, you said this place is huge, how big is it?" I've been in for so long and I've seen that there's only one main road, the river. ”

Ling Yu looked left and right, except for this main road, he didn't see any other forks.

The crocodile said. "No, this river branches about two kilometers in front, and there are many, many branches, and it's easy to get lost if you don't know the way."

No wonder, Ling Yu walked here from the time he came in. It's already several kilometers, and there's another two kilometers to walk before it branches, so it's a bit big here.

But even so, Ling Yu was very disappointed, that is. There may also be various situations with the previous branches, and there should be no exit.

That's not what he's looking for.

"Little crocodile, have you found any heavy places here? If so, you'll take me there! Ling Yu hadn't forgotten the purpose of coming in.

"Nope." The crocodile didn't think about it.

Ling Yu touched his nose, feeling that he was asking too much, the little crocodile had lived here for many years. Ask him if he feels very heavy, which is equivalent to playing the piano to a cow.

Lin Miaoyi and He Yufei felt strange when they saw that Ling Yu was staring at the crocodile with wide eyes and not fighting.

Was he really trained? That's too fast, right? He didn't seem to do anything but crack the crocodile's mouth at first, right?

"Ling Yu, it, it doesn't eat you?" Lin Miaoyi pointed at the crocodile in fear, but still didn't dare to approach.

Ling Yu joked. "It doesn't like my meat to be delicious, so you don't want to come?"

"I don't want it! You lied to me! Lin Miaoyi sneered. Knowing that Ling Yu was joking, he was not afraid.

"I didn't expect you to be so good, I didn't even see how you trained it."

The two girls had already admired Ling Yu's beast taming skills. Able to train such a large crocodile in such a short period of time.

"Now it's called a crocodile, I just talked to it, it didn't live here as soon as it was born, but it fell off like us,"

"But it didn't come in through the same entrance we came in. So you can rest assured now, there is a second exit, maybe we can get out. ”

Ling Yu's words made them breathe a sigh of relief. At this time, I was not afraid of the little crocodile, but I thought it was very cute, and reached out to stroke it.

They've grown so big. I haven't seen a crocodile yet. And it's impossible to pet a super giant crocodile so closely.

The three of them continued to walk forward, and sure enough, after walking two kilometers, they encountered a fork, Ling Yu asked the little crocodile to lead the way, although it didn't know where to get out, but in its territory, where there was danger, it knew.

At the same time, Ling Yu was also silently feeling the changes in the anti-gravity field around him, as long as he could figure out the magnitude of the force in each place, Ling Yu could build a model based on it, and then derive the source of the anti-gravity force!

Ordinary scientists can't do this without building models with the help of supercomputers, but Ling Yu is not an ordinary person and can naturally do this.

"Ling Yu, I'm so tired that I can't walk, why don't we rest?"

It's been seven or eight kilometers since he came in, and he's not tired, but not two women.

And now it's night outside, and because there is no sunlight here, only those glowing crystals, you can't feel the change of time.

"In this way, you stay here, I'll let the little crocodile protect you, I'll look everywhere, and explore the way by the way, how about it?"

Ling Yu didn't want to waste time here, just when they were resting, he could go to find anti-gravity substances, and with crocodiles to protect them, Ling Yu felt that there should be no danger.

"That's right, but we're afraid ......"

They are girls after all, and it is impossible not to be afraid in this desolate place.

"It's okay, I'll leave these things here, you can eat something when you're hungry, there's still water here, you can keep your strength up, I won't go far."

After Ling Yu left the backpack with them, he ordered the little crocodile to protect them here twenty-four hours a day before leaving.

Without them by his side, Ling Yu flew directly, especially here, Ling Yu felt that the force on his body was relatively small, and he could fly farther.

"Ouch......"

Suddenly, Ling Yu felt like he was being pulled down by something, to be precise, he was being pulled to the ground, and don't forget that he was actually walking upside down at the moment.

"Rub, why is there so much anti-gravity all of a sudden? That's already triple the gravity, right? ”

Three times, after counteracting gravity, there is also two times the upward anti-gravity force, which is equivalent to what was originally only sixty kilograms becoming one hundred and twenty kilograms in an instant!

"The further forward you are here, the stronger the anti-gravity is, could it be that the anti-gravity is coming from nearby?"

Ling Yu looked left and right, and the farther he went, even he felt that he couldn't move forward.

"Hey, what's up ahead?" Suddenly, he saw a hole in the middle of the water in front of him, like a huge whirlpool in the ocean!

"If I jump in, will I follow on the ground?" Ling Yu was stupid by his own thoughts, he had observed when he was outside, if this stream of water spewed out, it would inevitably form a huge fountain on the ground!

Obviously not.

"However, so much water has not been filled, there must be an outlet, go in and give it a try!"

Reluctant that the child couldn't trap the wolf, Ling Yu decided to go in and have a look. (To be continued.) )
