"What the hell are you?" Liang Shu asked, staring at the black frog.

The black frog was silent for a while, looking confused: "I don't know." Let me think about it,, I've slept for so long, I can't remember a lot of things. I remember that I seemed to have a master, called Tangshan City. He asked me to guard his lab. ”

Liang Shu's face suddenly darkened, this dog frog even swears: "Where is the laboratory you are talking about?"

"It's right below the waterhole. You're human, Boss Tang, uh, I seem to call him Boss all the time. He told me that if I met a human in the future, I could take him in. ”

"Alright, you take me in at once. ”

Liang Shu's so-called laboratory was full of doubts.

Humans were able to set up laboratories in the wilderness? And they were able to subdue the creatures of the wilderness. Could it be that what he knows from Zhang Yuan's mouth is only the tip of the iceberg, in fact, human beings have already gained a firm foothold in the wilderness?

"Then you let go of me, and I'll take you in. Black Frog said.

Liang Shu looked the black frog up and down, although the black frog's performance was seamless and there were no flaws at all, but Liang Shu didn't dare to go down with him with confidence. Underwater is not what I am good at, and if the frog attacks after entering, I don't know how I died.

"I suddenly felt safer to kill you and then go down on my own. ”

The black frog shuddered: "Don't, you can't enter without me, only I can open the door of the laboratory." ”

"Then I'm not going. ”

The black frog was about to cry: "Uncle, don't worry, I will never go back to water." You see on my stomach, there is a stone on it, that is my power stone, you take out the power stone, my power will disappear. Then you can rest assured!, and I finally ran into you as a human, and I need your help to get out of this place in the future. If I hurt you, I'll have to guard the lab here in the future, and an idiot will do that!"

Liang Shu ignored the big pile of nonsense behind it, and picked it up directly, and found that there was indeed a piece of skin on its belly that seemed to be able to be lifted, but after picking it twice, it was very strong and couldn't be opened at all.

Liang Shu glanced up at the black frog, and it immediately stretched out its paws and patted its belly, and with a click, the belly opened like a robot lifting the lid. A black stone-like organ was revealed. A large number of blood vessels were wound around it, and they were still beating up and down with the pulse.

Originally, Liang Shu thought that the energy stone that the black frog said was a stone, but when he saw this scene, he was immediately uncertain: "Are you sure this is the energy stone you said, not your heart?"

"Boss Tang also calls it a heart stone. ”

"You won't die if I take it out?"

"You can't die, you just lose your strength completely, and even if you put it back, it will take a few days to recover. But who told you not to believe me. You human beings are such small-bellied chicken intestines, and you never want to trust others. It's the same with my former boss, I have known for a long time that he is guarding against me, hum, how is it going, I honestly help him look at the laboratory and see now, in your human terms, what is this called, yes, this is called...... Ahh

Before it could finish speaking, Liang Shu directly reached out and grabbed the black stone, causing the black frog to scream.

Originally, all those blood vessels were rooted in the depths of the heart stone, but when Liang Shu grabbed the heart stone out, those blood vessels were like earthworms, and they all contracted one by one, and not half a drop of blood came out.

Liang Shu was slightly shocked in his heart, he knew that this black frog was not an ordinary creature, but this body structure was too weird.

"Maybe you'll have the answer in the lab. ”

Liang Shu looked forward to the secrets in the laboratory more and more.

The heart stone was caught, and the black frog completely turned into a soft egg, like 10,000 push-ups, and the soft lying on his stomach was limp in Liang Shu's hand and said: "I'm done, I can only rely on the boss to swim down by yourself when I enter the laboratory, I can only show you the way." ”

"Just show the way. ”

Liang Shu grabbed the frog and walked to the water's edge, and the black frog suddenly said: "The deepest part of the laboratory waterhole, you need to hold your breath, and you need to swim fast, otherwise you will lose your breath, can you?"

Seeing the black frog's contemptuous expression, Liang Shu sneered: "Otherwise, I won't go, and I will feel more convenient to eat you directly." ”

"Let's go!"

Liang Shu snorted, then grabbed the black frog and jumped into the pool.

However, less than twenty minutes later, Liang Shu re-emerged from the water, his face purple and blue. The black frog stayed in Liang Shu's hand and looked at Liang Shu with a sympathetic expression.

"Nima, how deep is it!" Liang Shu was furious.

"It's deep, less than half of the swim just now. ”

"Holy!"

Liang Shu looked at the black iron gene element on his body, there were still 3,860 points left, and he immediately consumed 2,540 points and upgraded the flippers to level 8. I dived all the way just now, and I didn't see the bottom after swimming for a long time, and I had no choice but to come back halfway, and even then I almost suffocated him to death.

Then Liang Shu took a deep breath and re-entered the water.

After level eight, the power of the fins finally manifested, and under water, a little hard kick can shoot out a few meters, more than three times faster than before.

Diving all the way, Liang Shu soon couldn't see anything, and could only rely on the black frog to guide him.

After about six or seven minutes of diving, Liang Shu suddenly saw a faint light.

The direction of the black frog's command was that area of light. Liang Shu immediately swam over with all his might, and when he came to the front, he saw that it was a stone door, and a fist-sized white bead was inlaid on the door, and it was that bead that glowed.

When he got to the door, the black frog's tongue spit out and inserted it into a hole in the white beads, and suddenly there was a click, and the stone door opened, and inside was a layer of water film-like things.

"Fast forward! The water film only lasts five minutes!!" the black frog reminded.

Liang Shu immediately crashed into it.

After entering, there was a click, and the stone door closed, and the water film disappeared.

Liang Shu gasped for half a minute before looking at the laboratory.

The interior was dimly lit, and the only source of light was the three night pearls inlaid on the roof. The laboratory is not very large, only about 200 square meters. On the left side of the wall is a three-meter-long table with bottles and jars, but all of them have accumulated a lot of dust and have been idle for many years.

There was a chair next to the table, with a crooked bone, draped over a black hooded trench coat.

On the other side were several large jars, also covered in dust.

Seeing this scene, Liang Shu's doubts became even heavier. It's only been a hundred years since humans entered the wilderness, but this place doesn't look like a hundred years.

"Look, is that your Boss Tang?" Liang Shu asked, bringing the black frog over and pointing to the dry bones on the chair.

The black frog sighed: "That's right, it's Boss Tang." Unexpectedly, Boss Tang has become a pile of bones. Time flies. ”

Liang Shu pinched the black frog in front of him: "Let me ask you, how many years has this place been built, and when did you come to the wilderness?"

The black frog thought for a moment: "I set it to wake up once in 10,000 years, and I woke up twice during this period, so it will be at least 20,000 years now." ”

“...... Damn!"
