After some preparation, Zhang Xuan and Tang Hao left the laboratory and set out towards the south side of the laboratory.

This is the first time Tang Hao has actually walked out of the laboratory in more than a year. Before, he had been secretly shuttled back and forth from the tunnel to see if he could meet someone sent by his father to save him.

Tang Hao had encountered several people, but without exception, they were all swallowed by the snake.

Apart from that authenticity, Tang Hao was almost blinded by the laboratory. Except for what the camera could take and what could be seen on the observation deck, Tang Hao had no idea what was outside the laboratory.

The two of them carried some cans and water and set off like this. As for the black monkey, Zhang Xuan was left in the laboratory.

Zhang Xuan did this out of two considerations.

First of all, the black monkey is the Jungle King. Its gene is undoubtedly something that all experimental subjects will compete for. Now no experimental subject knows that the black monkey is injured, so he dare not provoke the black monkey. But once it is discovered that the black monkey is injured, I am afraid that the Jungle King will bring to Zhang Xuan and the others at that time, it will be a devastating blow.

Second, Zhang Xuan didn’t know what was going on in this small world. It’s still a little bit to see if he could find a way out this time. Maybe he had to go back to the laboratory and leave the black monkey in the laboratory to shock those experimental subjects, and leave a place for himself to live.

This land presents a dark color, and even the trunks of the tree are black. The intersection of different matters makes everything here different from the outside world.

"Brother, why do I feel gloomy?"

Tang Hao shrank his head and followed Zhang Xuan.

Tang Hao's posture made Zhang Xuan speechless, "By the way, why are you also a master of Qi Control? The experimental subjects around you should not do anything to you."

Tang Hao said with a grievance: "Brother, I don't want to do this either, but I'm really scared."

"Let's go, I won't be afraid after a few fights."

Zhang Xuan patted Tang Hao on the shoulder and walked forward with great strides.

Tang Hao took a deep breath and tried to cheer up, but the cheering look lasted only a few seconds, and he became sluggish again. He trotted and followed Zhang Xuan and shouted softly: "Brother, don't go too fast, wait for me, wait for me!"

The destination Zhang Xuan set this time is not far from the laboratory.

According to normal people's ideas, the laboratory should be closest to the exit so that it can be convenient for entry and exit.

Along the way, although the two were careful, they still attracted many attacks from experimental subjects. These experimental subjects are extremely sensitive to the smell of the human body and are even more eager for human genes.

After killing seven or eight experimental subjects in a row, Zhang Xuan discovered that the experimental subjects in this small world are more powerful than the small world outside, which made Zhang Xuan a little confused.

From what Andre said, we can know that the small world outside was completely wiped out by the Shenyinhui, but now the experimental subjects are all run over from the small world now. These experimental subjects will be swallowed by each other. Gene evolution may be able to complete a large evolution, but why is each experimental subject stronger than the outside?

There is only one possibility, that is, there is definitely something in this small world that reinforces these experimental subjects in silence.

The two of them traveled through this small world and encountered a lake, which was on the camera, indicating the lake where the fish was selected.

In the video, Zhang Xuan hadn't seen that the color of the lake water turned out to be pure black.

The lake water is particularly calm, not even a single ripple, as if it is a pool of stagnant water.

However, Zhang Xuan and Tang Hao would not think so. When they saw the lake, they slowed down almost at the same time. What was the thing in the lake was clear.

If the fish opens its mouth, it will definitely be able to swallow any of them easily.

The two of them walked around the lake and continued to move forward.

In this way, Zhang Xuan and Tang Hao walked in this small world for three consecutive days.

This small world is very big, and the speed of both of them is not fast. After all, the overlords are out here. When they come in, Zhang Xuan can still grasp the position of some overlords, but now they have reached the depths of this small world. Zhang Xuan doesn't know what is ahead, so the two of them can only grop carefully.

"Dong!"

Zhang Xuan suddenly heard a violent sound.

"careful!"

Zhang Xuan's face changed, and an invisible air shield blocked him in front of him.

Tang Hao, who was following Zhang Xuan, was shocked and also posed for a pose to prepare for battle.

The two of them held their breath and observed the surroundings. There was no wind here. Except for the faint breathing of the two, there was no sound.

"Brother, what did you find?"

Tang Hao spoke in a low voice.

"Didn't you hear it?"

Zhang Xuan's eyes were solid and he kept scanning the surroundings. Here, there was no luck. If he really encountered such a terrible creature, he would have no place to run. If he was careless, he would be ruined by his own life.

"What did you hear?"

Tang Hao's eyes were full of doubts, "I just see you suddenly like this."

"You really didn't hear it?"

Zhang Xuan was surprised that the "dong" sound just now was particularly obvious, even ordinary people could hear it clearly, let alone a master like Tang Hao, his senses were much sharper than ordinary people.

"No."

Tang Hao's head was shaking like a rattle.

"All right."

Zhang Xuan breathed a sigh of relief. It seemed that his nerves were too tense. During these three days, the two of them had almost never relaxed. They had to leave one person to wake up when they were resting, and the person who was resting was also able to enter a state of fighting at all times because they were half asleep and half awake.

Zhang Xuan removed the invisible air shield in front of his body and was about to take a step.

"Dong!"

Another sound exploded in Zhang Xuan's mind.

"come out!"

Zhang Xuan waved his hand suddenly, and a phantom tiger instantly condensed from behind him, and then pounced on a big tree in front of him.

The big tree suddenly cracked into two pieces. Zhang Xuan stared at the back of the big tree, but found nothing.

"Brother, what's wrong?"

Tang Hao asked with confusion.

"You really didn't hear it?"

Zhang Xuan asked again.

"It's really not, brother, believe me, I won't joke about our lives."

Tang Hao looked anxious, afraid that Zhang Xuan would doubt what he had.

Zhang Xuan looked at Tang Hao with a suspicious look, analyzing Tang Hao's words and Tang Hao's recent behavior. From the beginning to now, Zhang Xuan has never really trusted Tang Hao. Once Tang Hao shows something wrong, Zhang Xuan will never hesitate and kill him directly.

"Dong!"

Another sound came out, and Zhang Xuan was about to make a sound, but suddenly he was stunned. This time, he understood why Tang Hao could not hear any movement, because this sound came from the bottom of his heart!
