Mecha training room.

Sheng Heng came out of the mecha cockpit, sweating profusely, and walked to a bench on the side to rest.

At this time, Cheng Wenkang also slowly climbed out of the cockpit of the mecha. Although he was also sweating, his complexion looked better than Sheng Heng. After he left the cockpit, the first thing he did was to rush to the refrigerator in the corner of the training room and get a bottle of ice water to drink. After drinking half a bottle, he finally had the strength to speak.

"I'm so thirsty." Cheng Wenkang took another bottle of water from the refrigerator and threw it to Sheng Heng who was sitting on the bench. "Boss, take it."

Sheng Heng looked up when he heard the voice and raised his hand to catch the water thrown by the other party. The moment he caught the water, Sheng Heng's fingers trembled violently and suddenly lost their strength and failed to hold it. The water slipped from Sheng Heng's fingertips and fell to the ground.

"Boss..." Cheng Wenkang was startled, then he seemed to have thought of something, his eyes fixed on Sheng Heng's fingers, "Your hand, is it hurting again?"

"It's okay, it will be fine after a while." Sheng Heng said nonchalantly.

Cheng Wenkang opened his mouth as if he wanted to say something, but in the end he said nothing. He just walked over and picked up the fallen bottle of water. When he was about to help Sheng Heng unscrew the bottle cap, the bottle was held by a trembling hand.

"I can do it myself. I can open the bottle cap." Sheng Heng took the water from Cheng Wenkang, then twisted the bottle cap with his fingers and twisted it hard twice before it opened.

"Boss, your training volume has exceeded the limit recently," Cheng Wenkang advised.

"How many hours do you practice a day? How many hours do I practice a day?" Sheng Heng said self-deprecatingly, "You are not considered diligent in the class. You practice five hours a day, and I only practice three hours. Am I exceeding the standard?"

"Boss, your hand..." Cheng Wenkang's words were automatically silenced by Sheng Heng's gaze. After a while, he said, "I'll go to the pharmacy to buy some medicine."

After saying that, Cheng Wenkang stood up and left the mecha training room, walking towards the pharmacy. After walking for a while, he suddenly had an idea and thought of someone.

In the dormitory of the Mecha Manufacturing Department, Yan Hao was studying the circuit diagram of a level 5 mecha. He seemed to have encountered some difficulties and was thinking hard.

"Stop pulling." He Shao walked over and gently patted Yan Hao's hand that was pulling his hair.

"Ah?" Yan Hao raised his head in confusion.

"You pull my hair every time you think. If you keep doing that, you'll become bald at a young age," He Shao threatened.

Yan Hao put his hand down embarrassedly, and it seemed that he just realized that he had just pulled his hair again. He had this habit since he was a child. Often, his hair would become messy after thinking about a problem. In his previous life, everyone in the laboratory was the same, so he didn't care.

"It's okay." Yan Hao replied.

"Nothing? Don't be reckless just because you have a hair growth potion. You need to shave your head before using the hair growth potion. Are you going to class with a bald head?"

"I mean, I won't be bald." He had thick hair until his death in his previous life.

"How do you know about the future?"

Yan Hao smiled and said nothing.

"By the way, I'm going out to buy some midnight snacks. What do you want to eat?" He Shao asked.

"I'll eat whatever you buy." Yan Hao is not picky about food, there are some things he cannot eat.

"You're really easy to take care of." He Shao couldn't help but rub the top of Yan Hao's head for a while, and only let go after Yan Hao dodged backwards. "Continue reading."

After saying that, He Shao went out to buy supper, while Yan Hao continued to read. He had only turned two pages when the light computer on his wrist suddenly rang.

"Senior Cheng." Yan Hao answered the phone, looked at Cheng Wenkang in the video, and greeted him with a smile.

"Little brother, are you free now?"

"Are you free? Senior, do you want to talk to me about something?" Yan Hao nodded obediently.

"It's not me, it's the boss."

"Senior Sheng Heng? Then why didn't he call me himself?" Yan Hao asked curiously.

"Well, the boss is embarrassed."

Yan Hao was immediately even more puzzled. What was it that made Senior Sheng Heng feel embarrassed and had to ask Senior Cheng to convey it?

"What's the matter? I will help if I can." Yan Hao said.

"That's great. You can definitely help me with this." Cheng Wenkang said immediately, "It's like this. For those of us who learn to drive mechas, our fingers will be strained to a certain extent. You know this, right?"

"I know. Because there are many operating instructions for mechas, mecha pilots have very high requirements for hand speed, so fingers need to be maintained regularly, otherwise they are prone to strain." Yan Hao said here, and suddenly reacted, "Senior Sheng Heng's hands are uncomfortable?"

"Yes, because the final exam is coming soon, and the boss has been practicing too hard recently, so..."

"Where are you?"

"Mecha training room." Cheng Wenkang replied.

Yan Hao glanced at the time and immediately said, "The pharmacy should not be closed at this time. I'll go buy some medicine. Wait for me."

After saying that, Yan Hao hung up the phone, put on his clothes and left the dormitory.

On the other side, Cheng Wenkang saw Yan Hao agreed and couldn't help but give himself a thumbs up for his cleverness, then turned around and went back to the mecha training room.

Sheng Heng had recovered a little by this time. Seeing Cheng Wenkang coming back in less than five minutes, he couldn't help but asked in surprise: "Why did you come back so soon? Where's the medicine?"

"Oh, well... I ran into my junior brother not long after I went out, and then I mentioned it to him."

"Who asked you to meddle in other's business?" Sheng Heng frowned.

"As soon as my junior heard that your hand was injured, he ran to the pharmacy and said he would personally prepare medicine for you. If you are not happy, I will call him now and tell him not to buy it." Cheng Wenkang said deliberately.

Sheng Heng paused, rolled his eyes at Cheng Wenkang, and said nothing more.

"A reserved and reserved person." Cheng Wenkang complained in a low voice and walked aside to eat.

About twenty minutes later, there was a knock on the door of the mecha training room. Sheng Heng's eyes lit up and he stood up to open the door.

"Boss, oh my god, you are injured, be a little more gentle." Cheng Wenkang reminded.

Sheng Heng hesitated for a moment, then sat down weakly.

Cheng Wenkang went to open the door, and the person standing outside was indeed Yan Hao, who was carrying a large bag of medicine.

"Junior brother, thank you for taking the trouble to come here. Come in quickly." Cheng Wenkang welcomed him in warmly.

"No." Yan Hao walked in and soon saw Sheng Heng sitting in the corner. He quickly walked over and said, "Senior Sheng Heng, how is your hand? Let me see it."

"It's okay, the fat guy is just exaggerating." Sheng Heng comforted.

"Let me see." Seeing that Sheng Heng didn't move, Yan Hao simply squatted down and grabbed Sheng Heng's hand hanging by his side, held it in his hand, and examined it carefully.

Although he had rested for almost half an hour, if you looked closely, you could still see that Sheng Heng's fingers were trembling slightly, and there was some redness and swelling at the joints.

"Senior, try to squeeze it harder and see if you can exert any more strength." Yan Hao looked up and said to Sheng Heng.

Sheng Heng's palm was a little stiff when Yan Hao held it. At this time, after hearing Yan Hao's request, his eyes gradually deepened, and then he pursed his lips and clenched his hands according to Yan Hao's request. In order to feel the strength of Sheng Heng's palm, Yan Hao did not pull his hand out of the other's palm, so Sheng Heng's grip directly wrapped his hand inside.

So this is what it feels like to hold my junior’s hand.

"Senior, is your hand injured?" Yan Hao suddenly asked.

Sheng Heng came back to his senses, and then nodded gently: "Yes, I was injured when I was a child."

"No wonder your fingers are so swollen. You can't do high-intensity training in your condition." Yan Hao said.

Sheng Heng's expression froze and he withdrew his hand: "I am a mecha warrior."

Yan Hao was stunned for a moment, then he understood. Senior Sheng Heng's hand was injured when he was a child, so he should know that he is not suitable to be a mecha warrior in his condition, but he still applied for the mecha driving department in college. There is only one explanation for this, he likes to drive mechas.

"Ordinary ointments are probably useless in your case. Let me help you mix the medicine." Yan Hao stood up and said to Cheng Wenkang, "Senior Cheng, can you give me a basin and a pot of hot water?"

"Okay, I'll get it." Cheng Wenkang hurried to prepare, and soon came back with a basin and a pot of hot water.

This time, Yan Hao opened the bag he brought with him, took out two packets of herbs from it, and poured one of the packets into the basin. He then poured in boiling hot water until it covered the herbs.

"Hey, junior, why didn't you buy the prepared medicine?" Finger strain is a common disease among mecha warriors, so pharmacy stores have special medicines for this type of strain. Those who need it only need to go to the store to buy the medicine, then mix it with hot water in a certain proportion, and soak it for fifteen minutes to achieve the therapeutic effect.

Of course, if during the treatment, a pharmacist can use his mental power to stimulate the efficacy of the medicine, then the treatment effect will be better. However, for common diseases like this, it is a bit too extravagant to ask a pharmacist to stimulate the efficacy of the medicine, so only some top mecha masters will do so. The reason why Cheng Wenkang called Yan Hao was not only to create an opportunity for his boss, but more importantly, he wanted Yan Hao to come and help stimulate the efficacy of the medicine. After all, Yan Hao studied pharmacy for six years in middle school, so he could barely be considered a pharmacist.

"Oh, this... this treatment effect is better." After being reminded by Cheng Wenkang, Yan Hao suddenly realized that he seemed to have made a mistake.

In the last few years of his previous life, he had been serving veterans on the military's convalescent planet. Every one of them had serious hand injuries, and in order to treat their injuries, Yan Hao spent a month adjusting the potion ratio. When he went to the pharmacy to buy herbs just now, he subconsciously bought the ones he was used to.

"Did you figure this out yourself?" Sheng Heng asked.

"Yeah." Although it was not discovered until more than ten years later, it was indeed discovered by him.

Yan Hao saw that the medicinal properties in the basin had been mostly stimulated by the hot water, and then motioned for Yan Hao to put his hand in.

Sheng Heng didn't hesitate and put his hands into the basin. The dark liquid went straight up to his wrists.

"Inject mental power." Yan Hao said again.

Sheng Heng was stunned and asked subconsciously: "Me?"

"Yes, inject your mental power into the potion." Yan Hao nodded.

"No way, little brother, you must have made a mistake. Stimulating the medicinal properties of a potion should be something that only a pharmacist can do. Even if ordinary people have mental power, they don't understand the medicinal properties of herbs." Cheng Wenkang asked curiously.

Mech warriors also have mental power, and the reason why they need pharmacists to assist in treatment is because they themselves do not understand the medicinal properties of herbs, and the medicine is made up of dozens of herbs. Once there is a mistake in the process of stimulating the medicinal properties, the efficacy of the medicine will change. Pharmacists can grasp this change through their own understanding of the medicinal properties, but others cannot do it.

"I have improved it, but I did not improve the efficacy, but the method of use." Yan Hao explained in the puzzled eyes of the two, "I once built a model, analyzed the main ingredients in the muscle soothing potion, and then calculated a very stable ratio. Under this ratio, the possibility of the drug being stimulated again and mutating can be reduced to 0.12%. In other words..."

"That means that there is no need for the pharmacist to use his mental power to stimulate the potion. Anyone's mental power can be used to stimulate the potion a second time?" Sheng Heng reacted immediately.

"Well, this improvement doesn't have much effect on the treatment, but it is more convenient to use." In the last life, on the military's sanatorium planet, there were only a dozen pharmacists, but there were thousands of veterans, and their hand injuries were very serious. Once they started to hurt, ordinary medicines were useless, and they could only rely on the pharmacists to stimulate the second time. But the disparity between the two was too great, so Yan Hao came up with this idea.

"Senior, please try to stimulate the medicinal properties yourself first, and then I will help you stimulate it once and you can make a comparison. I have tried it, and the difference in the efficacy of the two is within one percentage point." Yan Hao said.

"Okay." Sheng Heng responded, and then couldn't wait to inject his mental power into the medicine.

"By the way, in order to prevent the 0.12% error from happening, I added leaf vine to the medicine. Once the efficacy of the medicine deviates, the leaf vine will emit a smell similar to alcohol. So once you smell the smell of alcohol, stop stimulating the medicinal properties. This means that the medicinal properties in the medicine are no longer stable." Yan Hao has always been rigorous in his work, so even an error of 0.12% must be prevented.

After about five minutes, Sheng Heng's eyes gradually showed a strange light and he looked at Yan Hao in shock.

"Boss, how is it? Is it really effective?" Cheng Wenkang asked impatiently.

"Yes, it works." Sheng Heng said firmly.

"Then stop for a moment. I will use my mental power to help you activate the potion so you can compare them." Yan Hao said.

"No need." Sheng Heng shook his head and refused, "I have used the potion stimulated by the pharmacist before, and the effect is indeed similar."

"Oh my god, is it really that magical? I want to try it too." Cheng Wenkang immediately became excited, "Little brother, can I just soak the herbs in boiling water like you did just now?"

"Yeah." Yan Hao nodded.

Hearing this, Cheng Wenkang immediately ran to find another basin, and then prepared a basin of medicine according to Yan Hao's previous method, then put his hands in, and then used his mental power to stimulate it. After about two minutes, Cheng Wenkang shouted, "Oh my god!"

"It really works, boss, it really works, it's amazing. Junior brother, you are a genius." Cheng Wenkang.

"It's not that exaggerated. I just simplified the usage method. The treatment effect is still the same." Yan Hao said.

"No, your discovery is very important." Sheng Heng said immediately, "In the military, only mecha warriors above level six have the right to ask pharmacists to accompany them to treat hand injuries, but most other mecha warriors cannot enjoy this privilege, and these people are the majority. Yan Hao, although your discovery has not changed anything in the efficacy of the medicine, it can help more people."

[Pharmacist Yan Hao, thank you, you have helped many of us. ]

In his previous life, Yan Hao had studied medicine for more than ten years and had made many discoveries, but the only thing he had ever been thanked for in person seemed to be this improved formula that he had not spent too much effort to calculate. It was also one of the few good memories of his previous life.

"Yeah." Yan Hao nodded heavily, with a faint smile in his eyes.

His existence in his previous life was not meaningless, and someone had thanked him before.

And his smile made Sheng Heng stunned.

"Senior, your soaking time is almost up. Let me give you a massage." Yan Hao reached out and took Sheng Heng's hand out of the potion, and before the other party could react, he gently pressed the acupoints.

The tingling sensation from the gentle pressing made Sheng Heng's heart tremble.

Junior brother, you are teasing me, of course you are.
