The old man's voice soon attracted the attention of Su Luo and Yorkhanlong.

Hengde and his two men changed their faces and walked straight to the glass cylinder.

The same is true for Hu Mang, but the two people who focused on the dike were Hengde.

"lay down!"

The old man kept bubbles in his mouth, but the sound still fell into everyone's ears.

The old man stared at Yorkhanlong with a close eye.

Su Luo walked slowly to Yorkhanlong.

"Yorkhanlong, what did you guys take!"

Yorkhanlong sneered: "Su Luo, in this laboratory, you take what you think is suspicious, we take ours, and we will not violate the rivers!"

Su Luo naturally could not refute this sentence.

But from the old man's movements, she had seen that some extremely important things fell into Yorkhanlong's hands.

"Yorkhanlong, we suggest that we share what we have obtained."

"Why?"

"Since everyone is trying to overcome the source of infectious diseases, then everyone can share the obtained materials equally so that they can go back and study, right?"

Su Luo almost opened his mouth for a beautiful speech.

"Hmph!" Yorkhanlong sneered, "Impossible!"

"If you don't agree, don't want to leave here!" Gu Chenxi stood up coldly.

Yorkhanlong's eyes were cold, as if he was about to take action at any time.

Gu Chenxi's face was indifferent, but in fact he had already been prepared.

The old man began to knock on the glass cylinder.

Cracks quickly appeared on the cylinder, and water slowly flowed out.

Hendsell and his two gazes changed drastically, they took a step back, and suddenly took action together. The black and gray aura immediately followed the crack and rushed into the glass cylinder.

The old man's skin was quickly attacked by black and gray.

Hu Mang was watching quietly, he was ready to take action at any time.

The old man's skin was burned, hissing sounds were made in his mouth, and his eyes were instantly furious.

Bang!

He raised his legs hard, and his knees were pounded heavily. The glass cylinder shattered and a large amount of water flowed out.

Su Luo's expression changed slightly, and he stepped back instantly to avoid stepping on the water.

The two of Hengde and the others even attacked together, bombarding more black and gray auras on the old man.

The old man fought back angrily and knocked the two of them away with just one punch.

Such combat power made Hu Mang's face suddenly change.

This is not bad either.

"Boss! Let's go!"

Hend and the others immediately escaped, and Yorkhanlong turned into a lightning bolt and rushed out. As for the others in their team, they ignored it.

Su Luo wanted to chase him, but was stopped by Gu Chenxi.

The old man looked around, and the sharp light in his eyes flashed and disappeared.

"You won't chase after me!" He ordered loudly in a hoarse voice.

Su Luo turned his head to look at Gu Chenxi, and looked at the old man with caution.

Now, their biggest enemy is the old man in front of him.

Su Luo was puzzled: "Mr. Gu, have you noticed that the old man's eyes turned red and black."

Gu Chenxi nodded: "It should be because the laboratory has been invading the bar for a long time."

Hu Mang shook his head: "It's not entirely true. The old man's eyes were originally red. Only after being attacked by Hende and the other men did there be a black and gray switch."

Su Luo frowned: "It seems that's true."

While speaking, the old man's eyes had completely turned black and gray.

Then, he locked in Su Luo and rushed forward.

"careful!"

Gu Chenxi immediately blocked Su Luo from behind and fought with the old man.

Bang!

With just one move, Gu Chenxi was beaten away.

Hu Mang immediately bullied himself to attack.

However, it was only a few rounds that he lost.

But during this period, he also accurately stabbed the switchblade into the old man's chest.

The old man's eyes returned to red, and then stopped.

"A bunch of ants." He said condescendingly.

Hu Mang was shocked. It was like this, and the old man would not die? This is simply an indestructible monster!

The old man slowly walked towards Su Luo

Su Luo kept retreating, his body pressing against the wall.

"Remember! Catch up with Westerners immediately! Regain the source of infection! Otherwise, the world will face a catastrophe!"

Then, the old man walked into an iron cage and locked it himself.

"I am extremely poisoned by Westerners and my consciousness will be lost occasionally. In order not to hurt the innocent, don't open the cage easily."

Such a mutation was unexpected by everyone.

Gu Chenxi was the first to calm down, and he slowly walked to the old man: "Are you the person in charge of the laboratory?"

"yes."

"You're not completely a zombie?"

"Of course!" the old man sneered, "My consciousness has always been alive. But I didn't expect that the Westerners who were black and gray just now were so powerful that they could control the long-lost 'black and gray poison'."

"What?" Hu Mang's voice was shocked, "Black and gray and fishy poison?"

Maybe others don’t know the black, gray, fishy poison, but he knows it very well.

It is said that it is a completely lost poison technique, the former king of all poisons.

No wonder they felt that the two of them were inexplicably powerful when they met. They actually had such unique skills.

"The black and gray poison has invaded my body, and I will lose control intermittently." The old man continued to speak slowly, "The source of infectious diseases will only become more and more 'toxic', so you must snatch it back quickly, otherwise no one can escape when the disaster strikes!"

"Okay." Su Luo agreed immediately, "Let's go and take it!"

"Thank you!" The old man smiled tiredly.

Now, Su Luo and others realized that the old man in front of him was not a bad person.

"Remember, the source of infection is buamphetamine diethyltrytreptin dimethoxyamphetamine. Only by breaking these four out and breaking them one by one can you find the breakthrough of the current infectious disease."

The three doctors immediately recorded it.

They know each formula well.

Su Luo and others naturally had only a few understandings. After all, they have specialized in their profession, so they are not practitioners in medical and clinical practice.

"Now, the source of infection of amphetamine cathhinone is in your hands, but the most critical dimethoxy amphetamine has been taken away by those Westerners."

"Dimemethoxyamphetamine is the most critical ingredient. It was precisely because of the combination of dimethoxyamphetamine that an infectious disease broke out in the laboratory here."

"Okay." Su Luo nodded, "Don't worry, we will definitely grab the dimethoxy amphetamine back!"

"Well, you guys go." The old man's voice was heavy.

"You're not going out?" Gu Chenxi frowned.

"No." The old man's face gradually became painful. "I originally just wanted to develop a few rare drugs, but it backfired and caused infectious diseases to mankind, so I was really shameless to face it."

"But this is not your subjective mistake," Su Luo tried to comfort her.

"But it was my personal cause in the end. My team, except me, has become zombies. What's the face I have to live? Moreover, I'm now covered in black, gray and fishy poison, and occasionally lose my mind. Oh, go!"

Su Luo and others left the laboratory in a heavy mood.

When they arrived at the palace gate, they suddenly found that there were teams of Pear Country outside. Everyone was holding submachine guns.

Fortunately, Yorkhanlong was already caught by them at this time.
