Xu Cheng first observed all the invisible cameras around his temporary laboratory.

Fortunately, the five old men were very kind, giving him enough respect and privacy in this regard, and there were no cameras to monitor him.

Refining the potion was too simple for Xu Cheng, and he was already familiar with this piece and could make it.

Outside, as long as Ye Ting needs Xu Cheng, fruits and various delicacies will be served, and someone will be arranged to buy them and send them to his room.

As usual, after doubling the differentiated cells in a drop of Xu Cheng's blood, he extracted 5 needles with other nutrient solutions.

Xu Cheng entered the laboratory and spent half a day making antibody serum, and by the time he was finished, it was already night. After Xu Cheng doubled and refined the antibody serum, he forgot that Professor Coman had used up the genes about the turtle here.

He opened the window and said to Ye Ting: "Auntie, go tell a few old men that the medicinal herbs need a very important thing now." ”

Ye Ting asked, "You say." ”

Xu Cheng said: "You need a hundred-year-old turtle, remember, it must live." ”

Ye Ting nodded, and then walked over and told the five old men about it.

Zhou Zhen went to the Rare Zoo overnight and mobilized the relationship to transport a large sea turtle that was more than 100 years old, and it was transported by a large truck loaded with water.

Xu Cheng directly asked them to bring the turtle in, and then after he extracted enough genes, he didn't let the turtle lose too much blood and let them transport it back.

Because it was too late, the family members of the four old men's families had come once, and they all came to invite them back, but the four old guys just refused to leave. looked at Xu Cheng's room with longing eyes.

In the end, the family members were driven back by the four old men.

"We're going to stay up all night tonight." Guo Lao said.

Old Man Ye said energetically: "Accompany me, see who can't stand it." ”

Sure enough, at 1 o'clock in the evening, the four old men were a little tormented.

"If you can't keep it, go back, since this kid said that he wants to make medicine for you, I'm afraid he won't give it?" Old Man Ye despised the four old friends.

The four old men blushed, and Guo Lao snorted: "Brother Ye, seeing that you are so energetic, we are looking forward to that medicine even more, how can I feel that you have less wrinkles in the past two days?" ”

"yes, I feel a little younger when I look closely." Zhou Lao Dao.

"Eh, don't say it, I'll stay here and won't leave, and I won't leave if I can't get the medicine." Xing Lao said shamelessly.

At this time, I saw that the lights in Xu Cheng's room suddenly went out.

A group of four old men thought the end of the long day and waited for him to come out and say something.

Who knew that the lights were out, and Xu Cheng didn't come out.

When the four old men approached the outside of the room, they heard the sound of Xu Cheng snoring.

A group of four people wanted to bomb the lab!

A few of our old men have been waiting for you all day until the early hours of the morning, are you okay, turn off the lights and dream of Zhou Gong?

Just when the four old guys were thundering, Xu Cheng finally jumped out of a sentence: "I can't eat hot tofu in a hurry." ”

"Still pretending to be with us?" Zhou is old-fashioned.

Xu Cheng sighed in the room: "Think about boxing, square dancing, no crutches, no wheelchair, you can live for another 20 years, full mental state every day, and your body is like a living tiger......

"Say no more!" The four old men were immediately moved.

Then obediently turned around and walked out of the yard, there was a driver waiting outside.

After beating them, Xu Cheng came out and sat on the edge of Old Man Ye's stone table.

"If you don't want to marry your Aunt Lan to Zhou Zhen, you can directly say that your Grandpa Zhou is not such a tough person." Old Man Ye said.

"It's okay, it's all up to Aunt Lan and her own thoughts, it's good if she can have a home, it's a little bit I can do for my mother." Xu Cheng looked at Old Man Ye and said, "How does your body feel?" ”

"It couldn't be better." Old Man Ye smiled: "Now I will be examined every day, and those three imperial doctors are surprised every day what kind of medicine you injected into me." ”

"A new type of drug, it should be said that it is a biological drug, will be popularized in the future, and it will replace many of the current traditional drugs, but it is not possible yet." Xu Cheng said: "The three imperial doctors must have shown the test report to the four grandfathers, right?" Otherwise, they wouldn't have waited so anxiously. ”

Old Man Ye nodded: "You don't understand how painful it will be to live to our age, sometimes we actually want to die early, but we can't." ”

"I understand." Xu Cheng smiled bitterly.

The old man nodded: "So, without being entangled in pain and various aging diseases, who doesn't want to have a good dream every day or be as light as a swallow can take a step?" You look at the five of us, basically there will be an entourage at any time to follow and need support, sometimes there is no way to go to the park, it is not good to sit for a long time, food, drink, and smoking must be restricted and strictly required, and the life is not as good as a dog, but there is no way, you not only live for yourself, but also live for your family. ”

This is why the four grandfathers are so nervous about the results of Xu Cheng's development.

"Are you really sure you can make a potion?" Old Man Ye asked.

"You can do it, but in order not to attract attention, I will personally go over tomorrow to treat the four grandfathers, they are too affected by coming here, I don't want anyone to come to me in the future."

The old man understood what Xu Cheng was worried about, he was afraid that other people would come to Xu Cheng after they found out, and once Xu Cheng chose to refuse, then it would be an enemy, and he didn't like the feeling of this threat.

"Don't worry, there are five grandfathers to support you, whoever eats leopard gall let him try!" Old Man Ye promised.

Xu Cheng sighed: "My goal and stage are not in China, and I don't want to go sideways in China to save my five grandfathers, maybe I don't look down on this domestic stage, but as you said, I only hope that in the future, when I am tired, our motherland can accept me as my last harbor!" ”

The old man patted him on the shoulder and said, "Yes, don't worry, Grandpa Ye, I haven't promised anyone in my life, but I can promise you that no matter what happens in the future, as long as you return to China, the country will protect you." ”

"That's ...... I can go on a rampage without any worries. Xu Cheng smiled: "Old man, I want to borrow your car early in the morning, and I'm going to treat the four grandfathers one by one." ”

"Go ahead, I'll say hello to the driver." Old Man Ye said.

Xu Cheng nodded, and then prepared to go back to the room.

Old Man Ye suddenly called him and said, "Wait a minute, I feel that my strength has returned to its peak in the past two days, let's practice two moves?" ”

Xu Cheng: "This...... You don't need it, right? ”

Old Man Ye snorted: "I have already digested the kick you took last time, and I feel that I can completely resolve that kick, if you do it again, the old man is not false at all." ”

Xu Cheng sighed: "Old man, don't hide it, I only used three successes in that kick!" ”

Old Man Ye's eyes widened: "If you don't pretend to be dead?" ”'
