29 Biotype Scar Cream

"Hiss…"

"Oh…"

"Awesome feeling…"

After consuming the apple, Zhou Wen immediately felt alert, lively, and energetic. All his tiredness was gone in an instant! He became fully engaged in the process of DNA extraction once again. 

There was a saying that 'skills come from practice.' Following the constant extractions, Zhou Wen's speed was increasing faster and faster. He needed two hours to extract one DNA sample on average. 

When the sky brightened outside, Zhou Wen had finally extracted all the seven types of raw material DNAs necessary. 

His heart was filled with a sense of achievement as he watched the DNA samples in the refrigerator. 

Who else was capable of extracting plant DNA in their first attempt and do such a perfect job at it?

After he celebrated the joy for a moment, he felt a gush of faint lethargy wash over him. He had been bustling about for a full 24 hours since yesterday morning, and he almost did not have any breaks in between. 

Therefore, he decided to take a short nap first. But before doing so, he placed the DNA into a sterile box and sent it to the PCR laboratory located on the fifth floor. 

In order to prevent people who were coming to work from destroying his precious work, he left a note on the box on purpose to notify his peers. 

Then, he ordered a taxi lavishly and headed back to the campus straightaway. 

He went straight to bed upon returning to his hostel room without even brushing his teeth or washing his face. 

He slept through until noon and discovered that not a single person was in the room when he woke up. 

He took a shower and felt resurrected with energy. Then, he headed to the cafeteria alone for a meal. Zhou Wen suddenly remembered halfway through his meal that he had yet to open the loot box from yesterday. 

He brought up the system's inventory list and found a pitch-black treasure chest lying quietly inside. He clicked on it once, and the treasure chest levitated before his eyes. 

[Would you like to open the loot box now? Yes/No]

Zhou Wen took a deep breath and chose 'Yes' in immense anticipation. 

The black metal treasure chest opened up slowly with a glossy, green sheepskin scroll emerging from the inside. 

Zhou Wen took a glance and felt tremendously excited in his heart. He could tell at once that it was a medical formula. It was rather impressive, just as expected. A dialogue box popped out. 

[Congratulations, you receive Biotype Scar Cream Formula X1]

"Good stuff, good stuff…" Zhou Wen was excited beyond comparison just by reading the name. 

A person would experience some knocks and bumps from young to old, and those often left behind some hideous scars. There were also scars from burns and those left behind from undergoing surgeries. 

According to the vain mentality of modern people today, if the Biotype Scar Cream was truly capable of removing all sorts of scars caused by physical, biological, and chemical injuries, the value of the formula was simply immeasurable. 

The rare Black metal loot box was different, just as expected. It made his hard work over the days worthwhile. 

He was excited about it for quite some time and was planning to study the formula for a while, but he remembered about the rice root aphid experiment soon afterward that required a large number of points to increase the experiment progress. He should not squander his points casually at this time. 

Soon afterward, his vision shifted toward the XP value, and he found that it had already reached 1000 points so he could upgrade his course. 

He took a glance at the course content list and discovered that Botany was added to his subcourse, surprisingly. 

After taking two glances, he shifted his gaze toward the Immunology course. 

This particular course was the most challenging subject in the entire Biology program. He could tell from the XP value that the other courses' starting value was only over 100 and even 200 points while Immunology only had 50 points. 

This was because there were too many courses that overlapped and interlinked with Immunology. For example, what were the types of cells in the human body, how were they divided into different types, which genes were involved in regulating the cells, the characteristics of metabolism, the changes of cells after an infection, which types of medications to use, what were the risks…

Countless courses were involved in this course, including biochemistry, pharmacology, virology, oncology, etc. 

As a result, the system's brief information on Immunology was 'Allows you to understand the mysteries of life!'

Yet, one could imagine how difficult this course could be. 

Of course, a person could definitely become an outstanding doctor upon excelling in Immunology. This was because the person would be able to understand the principle of curing illnesses rather than following someone else's experience blindly. 

After pondering about it, Zhou Wen chose to upgrade his Immunology course. 

In the next second, countless Immunology knowledge surged and filled his brain just like rivers converging into the sea. Soon afterward, the superficial knowledge he had previously acquired turned into a thorough understanding in an instant. 

He understood how the cell division in the human body, including which genes were affected. He had also learned about the characteristics of metabolism, the changes that happened upon acquiring an infection, and even the application of medications. 

This had turned into knowledge that could not be erased from the depths of his mind. 

Zhou Wen felt relaxed. Immunology knowledge was a supplement to biochemistry and pharmacology, which allowed him to understand Biology even clearer now. 

Of course, he was still quite a distance away from excelling at Immunology. 

…

After lunch, Zhou Wen rushed to the hospital. 

He had just arrived at the entrance of the campus when his phone rang. He took it out and took a glance to see it was an unknown local number. 

"Hello, who's on the line?" Zhou Wen walked toward the entrance while he picked up the call. 

A sweet, female voice was heard coming from the phone. "It's me, Xu Shuangyu."

Zhou Wen replied instantly, "Huh, why are you calling me?"

Xu Shuangyu said in a disgruntled tone, "Did you forget to bring your eyes with you before you left your house? Why can't you see such a huge person in front of you?"

"Where?" Upon hearing that, Zhou Wen stopped and looked around him. He found Xu Shuangyu in a baseball cap sitting under the shade of the tree diagonally in front of him. 

She was dressed in a black and white striped long-sleeved shirt and a pair of straight bottom jeans. She looked refreshing, simple, and exuded a feeling of freshness and naturalness. She looked just like a clear, simple, beautiful scroll painting. 

Zhou Wen hung up the call and stood still while waiting for her to come over. 

Xu Shuangyu raised her chin with an expression that was obviously suggesting - 'You come here!'

Zhou Wen lowered his head to check the time on his phone. 

His intention was clearly displayed on his face - 'I'm very busy. If you're not coming over, I'm leaving now!'

It was a master's trick in negotiations not to be the one needing something. It was very apparent that Xu Shuangyu could not defeat the desireless Zhou Wen. 

Just as Zhou Wen assumed the mannerism of leaving, she walked over to him. 

Xu Shuangyu raised her chin and said with an unpleasant expression, "Will it kill you to take a few extra steps to walk over?"

Zhou Wen smiled and replied, "Since it won't kill you, why don't you come over then?"

Xu Shuangyu said with widened eyes, "Can't you see a huge person like me standing before you now?"

Zhou Wen added, "That's what I just said. You're already here, so why would I still go over then?"

Xu Shuangyu's delicate cheeks trembled a little, and her gaze wavered, akin to an exquisite woman from the south of Yangtze River but also tinged with the unyieldingness of a northern girl's romantic charm. 

Xu Shuangyu gritted her pearly whites in a rage and asked, "You've always been single throughout your four years in the university, right?"

Zhou Wen quickly responded, "How do you know?"

Xu Shuangyu continued, "For a man with such a low emotional quotient for relationships, if you can get a girlfriend, the sun would be rising from the west."

Zhou Wen chuckled. "You're wrong. I don't get involved in relationships, not because I can't get a girlfriend but because it's me who didn't want to be in a relationship. That's because…"

Suddenly, he turned around and left before he finished the sentence. This was because he knew that Xu Shuangyu would follow him from behind to find out the reason. 

Just as he had expected, Xu Shuangyu followed by his side and asked, "Tell me, what is the reason?"

"Because I can't afford to provide for her."

"Heh…"

Xu Shuangyu gave a disdainful scoff. "You don't have the capability to provide for a girlfriend, yet you put the blame on the girl. Could it be that all the guys in the world with not-so-favorable family backgrounds don't have girlfriends? I don't think so, right? At the bottom of this, it's your fault for having a low emotional quotient. That's why no girls like you."

Zhou Wen continued, "You're right, my emotional quotient in a relationship is too low, and no girls like me. Is that okay?"

"That's how it's supposed to be."

"So be it then. I'm busy, talk later…"

Upon saying that, Zhou Wen left in a rush. 

Xu Shuangyu gazed at his departing silhouette and wrinkled her nose to let out a grunt. Then, she turned around and headed back. 

She took two steps before she suddenly stopped and turned around to take a look at Zhou Wen again, only to find that his silhouette had already vanished without a trace. 

"That's strange. Why do I keep bumping into this chump recently?" Xu Shuangyu complained in her heart before leaving. 

Zhou Wen arrived at the laboratory department and did not procrastinate even for a minute. He immediately began to engage in PCR amplification. 

The process was different from DNA extraction because PCR amplification could be performed on multiple samples simultaneously. 

Therefore, Zhou Wen prepared all seven plant DNA samples in the PCR machine and began preparing the bio-enzyme needed for later. 

This process was much easier than extracting plant DNA as he only needed to add in the different types of enzymes according to the strictly designated ratio. 

The plant DNA amplification was completed by half-past four in the afternoon. 

He removed the samples from the thermal cycler one by one and checked on them. The amplification effect was extremely good. 

Next, he prepared for a series of complex sterilization procedures according to the professional biotechnology pharmaceutical process. 

However, Zhou Wen privately produced the medication in a laboratory, and there was no need for marketing and sales of this product. As a result, he could skimp on some steps and utilize more straightforward procedures in the separation and purification, concentration, crystallization, and others. 

This saved him more than 90% of time. 

By three in the afternoon, the first batch of 12 Biotype Pain Relief Medication was produced successfully. 

The final step next was a clinical trial for the medication...
