"Why are you hiding so far?" Zhou Jianren poured the unknown liquid in the jar on the pork belly on the ground, and when he saw Zhang Fan and Li Mu hiding far away, he was a little surprised and asked suspiciously.

"No, no...... It's nothing...... Uncle Zhou, go on! Zhang Fan smiled awkwardly and motioned for Zhou Jianren to continue.

"That's right! Right, right! Uncle Zhou, go on, don't worry about us! Li Mu smiled bitterly and spoke. Seeing this, Zhou Jianren said inexplicably, turned his head again, and began to get busy.

He took out a pair of rubber gloves from the system backpack and put them on his hand, took out a small brush, leaned over, and began to carefully apply the liquid poured on the pork belly evenly to every inch of the meat.

After applying it for about a while, Zhou Jianren threw the small brush away, took off the rubber gloves, took out a lighter from his pocket, and put it on the pork belly.

With the flame of the lighter, the moment it was hitting the pork belly, the next second, the fire burst into flames, spreading rapidly along the corner of the pork belly, just a photo, and the whole piece of pork belly was ignited.

Seeing this strange scene, Zhang Fan and Li Mu were startled, and they distanced themselves from each other. Not only them, but even Su Qian frowned slightly when she saw this scene, obviously Zhou Jianren's operation made her feel novel.

She had also studied chemistry before, but it was the first time she had seen Zhou Jianren's operation. ....... The flame on the pork belly burned hotly for a few minutes before it slowly extinguished.

The extinguished pork belly exudes a rich and tangy aroma, which is mixed with the inexplicable smell of Huoxiang Zhengqi water, which makes people feel dizzy and swollen after smelling it for a long time.

Smelling this choking smell, Zhang Fan and Li Mu's faces changed slightly, and they immediately covered their mouths and noses, afraid that they would accidentally inhale this strange aroma into their lungs and be poisoned.

At this time, Su Qian watched for a while, took out three N95 masks from the system backpack, and handed them to Zhang Fan and the others respectively, asking them to wear them.

Looking at the masks handed over, Zhang Fan and the others were stunned for a moment, reacted, and hurriedly put them on. Su Qian really deserves to be a doctor, and she even carries this kind of mask with her.

"That's it! Now just throw the pork belly into the river and you can get rid of these piranhas! Zhou Jianren didn't know where to take out a gas mask and put it on his face, and said with a smile.

After explaining to Zhang Fan and the others, Zhou Jianren took out a steel fork from the system backpack and held it in his hand, poked it on the pork belly, and then carried it to the river, and then threw the pork belly down.

"Don't worry....... The drug applied on this is not very harmful to the human body, but it is ...... For non-human animals, it is extremely deadly!! Zhou Jianren put the steel fork back into the system backpack and said in a flat tone.

Hearing this, Zhang Fan's eyes widened and his face was strange. Good guys, if this drug is not harmful to the human body, why don't you take off your gas mask.

Although there was no difference in their hearts, Zhang Fan and the others did not say this sentence in front of them, but just muttered in their hearts.

They don't want to provoke the professor of chemistry for no reason, if they really annoy Zhou Jianren, I'm afraid that the two of them don't know how they died.

This piece of pork belly that was seasoned by Zhou Jianren entered the water, and in just a few breaths, it attracted a large area of hideous and terrifying piranhas.

The terrible piranha grinds its teeth with a numbing scalp and scrambles to pounce on the topped pork belly.

In just a few seconds, the seasoned pork belly was eaten up, and there was not even any residue left. After a while, the piranhas that had been gnawed on the fish overflowed with white foam in their mouths, and it didn't take long for them to turn their bellies and float on the surface of the river without moving.

"It's done!"

"It's now! The effect of the drug only lasts for five minutes, and once it is too long, the medicine will be washed away by the river! Zhou Jianren looked at the piranhas on the river densely flipped their bellies, his face couldn't help but be happy, and he hurriedly urged Zhang Fan and the others.

"Who's coming first?" Zhou Jianren asked. Hearing this, Zhang Fan and Li Mu glanced at each other, their expressions hesitated, no one dared to cross the river first, if there were other surviving piranhas in the water, then they would really die.

Just when the two of them were in a dilemma, Su Qian sighed, walked out slowly, and said, "Let me come!" Hearing Su Qian's voice, Zhang Fan's face turned slightly red.

This kind of dangerous thing, no matter how bad it is, you can't let a woman like Su Qian do it, so Zhang Fan, a man, is really shameless.

"That's it! Su Qian, wait a minute...... Let me do it first! Zhang Fan walked out quickly, stopped Su Qian, and without waiting for Su Qian to reply, he took out the bronze coffin nail from the system backpack and held it in his hand.

If there is really any danger, at a critical moment, perhaps the bronze coffin nail can also play a life-saving role.

Su Qian looked at Zhang Fan, who had stopped her, and her heart trembled suddenly, and a different kind of emotion gradually came to her heart, and she was silent for a few seconds, and finally nodded shyly.

Holding the bronze coffin nail, Zhang Fan jumped into the water with a puff. Just for a moment, the cold, cold that penetrated deep into the bone marrow, like a maggot that eats away at bones, rushed into Zhang Fan's pores wildly, making him shiver uncontrollably.

The river is bottomless, and the turbulent river almost washed Zhang Fan down. But fortunately, Zhang Fan's physical strength increased to 5 points, and he stabilized his body with only a slight adjustment.

Zhang Fan gritted his teeth and swam desperately towards the other side of the river. Luckily, his luck was good, and the imaginary piranha attack didn't happen.

It seems that Zhou Jianren's medicine has played a role. A minute later, Zhang Fan swam to the shore wet, turned his head and waved at Li Mu and the others, telling them that they were safe in the water and could come over.

Seeing that Zhang Fan passed safely and soundly, Zhou Jianren nodded, and then he was the second to enter the water. Zhou Jianren entered the water, Su Qian glanced at it and followed closely, Li Mu saw that everyone had passed, he could only muster up his courage and hurriedly followed.

About ten minutes passed, and Zhou Jianren and the three of them finally passed safely.

"It's really thanks to Uncle Zhou this time, otherwise we wouldn't have gone so smoothly this time!" Zhang Fan gave Zhou Jianren a thumbs up.

"Haha! We're all friends, and that's as it should be! Zhou Jianren laughed, waved his hand, and told Zhang Fan that this was what he should do.

"Since you're here safe and sound, let's go quickly!" Zhou Jianren wrung out his wet clothes vigorously, and looked back at the river behind him with palpitations.

In fact, it was mostly due to luck that he was able to come over unharmed, and he didn't have much confidence in the effects of his drugs, to be honest, and he was also afraid that he would be attacked by piranhas on the way across the river.

Zhang Fan and the three of them nodded, answered, and walked towards the road ahead.
