Travel through the 90s with the system, dig your own grave first at the beginning

"Mr. Lu, I'll call you Brother Lu. I'll give you the money first. You can check the fees you need to pay and pay them first." Gu Zishu put down his backpack.

"Thank you so much." Lu Chang really didn't know what to say. Seeing Gu Zisu taking out his schoolbag, he quickly went to the nurse's station to borrow paper and pen.

After Zishu had written the check, Lu Chang handed over the IOU he had just written.

"Student Gu, consider this money as a loan from me. If you can't pay it back within three years, I'll mortgage the house to you. Is that okay with you?" Lu Chang didn't rush to take the check that Gu Zishu handed over, but showed the IOU to Gu Zishu first.

Gu Zishu looked at what was clearly written on the paper and understood that this was a guarantee made by the other party. "Okay, you can take this and pay the fee directly."

"Thank you, thank you." Lu Chang took the check and ran towards the overtime payment window of the hospital.

Gu Zishu couldn't understand why an ordinary calligrapher, who hadn't offended anyone and wasn't blocking anyone's way, was poisoned? And it was an unknown poison. It definitely wasn't an accidental ingestion, so it could only be someone did it on purpose.

"Oh, right." Gu Zishu suddenly remembered the Japanese guy he met at school. It's not that Teacher Lu didn't block other people's way. Maybe it was because he proposed that they compete with the Japanese guy and organize a calligraphy competition on their own that he blocked other people's way.

I told this suggestion to Teacher Lu myself, and it must have been proposed by Teacher Lu and others afterwards. Teacher Lu also put in a lot of effort in the subsequent cooperation with the TV station. The Japanese are the most vindictive.

Even if Gu Zishu doesn't watch TV, he knows that this calligraphy competition in the country is very popular. The national TV station now has a special time slot every Saturday night to broadcast the highlights of the competition.

The finals after the new year will be even more exciting.

As for the competition that Nosuke organized, I've never heard of it. It must have been stillborn. If he wanted to take revenge on Teacher Lu, poisoning him is also possible. Aren't these Japanese people fond of doing things like this?

Thinking of this, Gu Zishu hurriedly ran towards Lu Chang.

"Brother Lu, have the police investigated the helper from the island country? He wanted to learn calligraphy from Mr. Lu before but was rejected by Mr. Lu. Later, he wanted to organize a calligraphy competition in our country to earn some money.

As a result, it was offset by the project that Teacher Lu participated in later. Did they poison Teacher Lu in revenge? "Gu Zishu told Lu Chang his guess.

Lu Chang was stunned. He really didn't expect that there was something about the island country involved.

"Nosuke, I've never heard of this person?"

"Isn't there a person named Ma Liangyou in the calligraphy world who is a sworn enemy of Mr. Lu? That Zhizhu is Ma Liangyou's nominal disciple.

If it is something from China, the doctors will know what kind of poison it is after checking it, but if it is from abroad, the scope is wide. "Gu Zishu reminded.

After being reminded like this, Lu Chang paused. He was not ignorant. He knew Ma Liangyou. When Gu Zishu said that, he felt that this was the most likely possibility.

"Wait a moment here. I have a classmate who is working outside now. I'll make a few international calls to ask." Lu Chang said anxiously.

"They may not necessarily be from the island country. These things may be from other countries." Gu Zishu said again.

Lu Chang nodded and ran outside.

Although he himself is an ordinary person in China, his classmates who can go abroad are not ordinary.

Some of the calls were answered, some were not, but it was impossible to get a reply so quickly. Some things they wanted to investigate would take some time.

But at last there was a direction, and Lu Chang breathed a sigh of relief.

And Gu Zishu, who was sitting inside, waited for Gu Ruosheng who arrived as quickly as possible.

"Where's the medicine?" Gu Ruosheng was not the kind of person who would hesitate. After all, he came here just for this matter.

"Here." Gu Zishu took out a bamboo tube from his pocket. There was still half a pill left in the tube. It was obvious that it was the pill he had used to make himself thinner.

"Where's the other half?" Gu Ruosheng felt heartbroken when he saw that only half was left.

"When we went to our teacher's house before, the teacher's father fell to the ground and couldn't get up. It was you who invited Doctor Xu. You forgot." Gu Ruosheng remembered as soon as Gu Zishu said this.

Suddenly he didn't realize that saving one person was more important than saving more people.

"What should we do now?" Gu Ruosheng sat down next to Gu Zishu, took two deep breaths and said.

"Teacher Lu has been poisoned. This should be able to save him." Gu Zishu said, pointing to the intensive care unit.

Gu Ruosheng looked at the half pill and said, "Are you sure you want me to send it in?

Once I go in, I won’t be able to make the decision. There are definitely more people lying in there than you can imagine, young, old, respected, and with a bright future ahead of them.”

……

"To be honest, including this half, I still have 3. How about I let you do it?" At worst, he could earn more spirit stones in the immortal world and buy more pills like this. Pills for healing injuries and diseases are very precious to ordinary people, but for the immortals who fight as a daily routine, they should be a necessity of life. He might even learn to refine pills in the future, so this would be no problem at all.

"Okay, leave this matter to me." Gu Ruosheng grabbed the other small bottle from Gu Zishu's hand.

There are many sick people in every hospital. With these three pills, I believe that with their team, it will be no problem to develop this medicine.

Gu Zishu watched Ruosheng walk away with the things. After a while, he changed his clothes and followed several doctors into the intensive care unit.

After 10 minutes, the person came out.

"How is it? Is it done?" Gu Zishu went forward.

"Don't worry, Teacher Lu has woken up. It won't take long for him to wake up. Let's see if there are any residual toxins and whether it will affect his body in the future." Gu Ruosheng said a few words, "I still have to go talk to a few other people, so I won't be here with you. I've taken the medicine. When the results come out, you will have a large part of the credit on the military medal."

"Okay, let's go." Gu Zishu waved his hand. If these people could really research this kind of elixir, maybe he could become a medicine dealer in the cultivation world in the future. After all, industrial production is much faster than refining pills one by one.

Gu Zishu didn't stay here for long. He waited for Lu Chang to come back, said hello to him and left. Although he contributed, it was not only because of the friendship between the two of them, but also because he couldn't bear to see such a good calligraphy teacher die for such a reason.

If he hadn't defeated this Nosuke, he would have really thought he was the best in the world.
