Regarding the principles behind the mechanism, Li Hu did not understand either. He stayed to the side to watch the engineer's skill and after a while, he had already repaired half of the machine, and seeing that there was nothing more to do, Li Hu left and returned home.

Li Hu flipped through these five ancient books, imagining the medicine in his mind, but he was still unable to find a suitable method. Sitting on the sofa, pondering hard, Li Hu suddenly looked at Tiny, playing with the cold dagger, feeling that it was difficult to adapt to, but Tiny, on the other hand, liked it more and more.

Li Hu instructed.

Li Hu stood up, walked to his own bedroom, took out a few things from the cabinet, took out a bowl, and poured all of the things into it.

They were all bottles and jars. Inside the jars, there was some powder, and it was all extremely poisonous.

This was what Li Hu had used to research Yi Yuan a while ago. As a treasure of China, the contents of the ancient Chinese medicine did not seem to be its appearance, it looked so simple, and there were even more things inside. Li Hu became more shocked by the research.

This poison was precisely what it was concocted. Although it looked like a poison on its own, if used properly, it could also become an antidote for people.

But Li Hu had concocted this medicine now, it was highly toxic.

Seeing this bowl, Li Hu hesitated. He did not know if he was right, he took the dagger away, and placed it inside the pill.

This bowl was very turbid and the color of the liquid was black. It disappeared at a speed visible to the naked eye. After a while, it turned transparent again.

He picked up the silver needle that he had prepared earlier and inserted it gently. The silver needle didn't change color at all.

Could it be that this dagger could dispel the poison?

Although the silver needle test water had no poison, Li Hu still did not dare to drink it. He placed the water in a bottle and directly rode the electric vehicle over. They still had the facilities like this, so he placed one bowl of water in the inspection department. Soon, the results came out. It was a very pure bottle of water without any poisonous substance.

"I didn't expect this to be an unexpected surprise."

Li Hu was holding onto the dagger, he was extremely happy, he never thought that this dagger could have such an effect, with such an effect, he could use the dagger, and there were many methods that he could succeed.

Li Hu took out his mobile phone and dialed a number. It was the old man who was at the hospital back then.

Before he left, he left a message saying that if he thought of a good idea, he would give him a call in time.

"Isn't this little brother? "Why is it that the tea leaves are fine? I'll buy as many tea leaves as you have." Just as the call connected, the old man's words entered Li Hu's ears, causing him to have a headache. He had been running outside the past two days and did not meet them.

"No, no, no. I found a way to treat it."

"Really?" Upon hearing that Li Hu had found a way to treat his injuries, the elder's tone of voice became different, and he became even more serious.

"It's true."

"Good, that's truly the best. My old brother cannot be delayed any longer either. If we continue delaying, there might be a huge change in our family. If you are able to cure him, then you will be his savior."

"Then I'll be there right away. Let's gather at the hospital."

"Stay at home, don't move. I'll send someone to find you right away."

As he said that, the old man immediately hung up, Li Hu also put his phone back in his pocket, he rode the electric vehicle back home, and just as he reached his house, he saw a car parked in front of his house.

"Mr. Li Hu, please get on the carriage."

The driver looked to be very young, around 20 years old, wearing sunglasses and a suit. Seeing Li Hu very respectfully open the car door to let Li Hu in, then closed the door and left.

After a while, he was at the hospital. Li Hu did not dare delay any longer and immediately got off the carriage to rush to the sickroom, looking at the elder's condition, it was even worse than the situation two days ago. At least a few days ago, he could see that his skin was a little pale, but it was completely dark now.

The poison had already sunk deep into his marrow, and to be able to persist was entirely due to the quality of this old man. But even so, he was afraid that he wouldn't be able to last much longer.

"When this old guy was young, only an athlete's physique was particularly good. When he gets old, he would love to climb mountains. If it was me, I'm afraid I wouldn't even last a day."

The old man standing beside Li Hu saw that his old friend had changed into this. He already knew the method to cure the poison and felt a lot more relaxed.

"Old sir, please close the door. Don't let anyone see it."

Seeing Li Hu's serious expression, the old man nodded his head and quickly went out to instruct his men to close the door. He told them to guard the door and not let anyone near it. He also took out a few pieces of cloth and covered up all the glass on the door.

Li Hu moved over to a small stool and sat in front of the old man. He took her hand, whose palm was already turning black, and took out a few silver needles from his bosom. He checked the acupuncture points, and then used a small knife to lightly cut the old man's carotid artery.

The blood inside was black, accompanied by a fishy stench.

"This old mister has been poisoned and is probably related to snakes. However, I also don't know what this poison is like. I'm afraid he has a doctor at home and his medical skills aren't shallow either."

Li Hu said as he watched.

The old man standing behind Li Hu suddenly had a change in expression, as though he had thought of something, but quickly recovered.

Li Hu gently placed the dagger on the old man's wound. As expected, this dagger, was like someone who had not drunk water for many days in the desert, meeting with the poison. It was exceptionally excited, to the point where Li Hu could feel that she was happily shouting, what kind of blade was this?
