That night, Jiang Fan took Chu Ruoxi to visit Mr. Long.

Mr. Long is now nearly 70 years old. He looks much older, but he seems to be in good spirits.

When he saw Jiang Fan coming back from the moon to see him, he was so happy that he cried with joy.

Mr. Long never married or had children for the sake of scientific research in Long Country.

He usually lives alone.

When he first retired, he felt extremely lonely inside.

He has been living in Longke University, and many people usually come to visit him.

But he already felt empty in his heart. Later, he really couldn't sit still, so he went to the principal and said that he would go back and take over the class.

But the principal was worried that his body couldn't bear it, but the stubborn Mr. Long insisted on taking over the class.

In the end, the principal had no choice but to agree.

In fact, Long Lai's idea is very simple, he just wants to pass on his life experience to these young people, and finally make some contributions to the country.

"Teacher, you still teach, can your body handle it?"

Jiang Fan is still a little worried about his teacher's health.

"Don't worry, your teacher, I'm in good health. I'm going to sign up for a marathon in June. Haha..."

Mr. Long said happily.

"Grandpa Long, you are young and old now, so you must pay attention to your health."

Chu Ruoxi was also a little worried.

"Don't worry, little girl, I promised Xiaofan that when you get married, I will be your witness. I still remember this! Hehe..."

Jiang Fan told Mr. Long at the beginning that when he and Chu Ruoxi get married, he must ask Mr. Long to be his witness.

Unexpectedly, several years have passed and Mr. Long still remembers this incident.

Jiang Fan was still quite touched.

"Teacher, I have proposed to Ruoxi..."

Jiang Fan told Mr. Long about his proposal to Chu Ruoxi, and Mr. Long was very happy after hearing it.

"Okay! Haha..."

Mr. Long has no children. He now completely regards Jiang Fan as his own relative. Seeing that Jiang Fan and Chu Ruoxi have a result, he is happier than anyone else!

"Xiaofan, you have to have two drinks with the old man tonight."

"Okay, teacher!"

…

On the fourth day, Jiang Fan and Chu Ruoxi went back to Lingzhou City.

They stayed at home until the sixth day.

Longguo's top brass called Jiang Fan on the 1st, and Jiang Fan had to return to Kyoto.

After arriving in Kyoto, after Jiang Fan sent Chu Ruoxi home, he went directly to the No. 1 office.

"Xiaofan, have you been resting like this these past few days?"

No. 1 asked Jiang Fan with a smile.

"Well enough!"

Jiang Fan replied with a smile.

The two then exchanged some pleasantries, and Jiang Fan asked No. 1.

"Leader No. 1, has something happened? You are looking for me in such a hurry."

"Yes!"

Number 1's expression then turned serious.

"According to reliable information, the beautiful country has developed a super battery using lunar energy ore."

"Super battery?"

Jiang Fan was a little surprised!

"Leader No. 1, do you know the performance of the beautiful super battery?"

Jiang Fan asked.

"I don't know the specifics, but I heard that the performance of the super battery they are researching is more than 10 times that of your previous lithium iron phosphate power battery!"

"10 times?"

Jiang Fan was not too surprised after hearing this.

He is very aware of the energy contained in the lunar energy ore.

"What research is our Dragon Kingdom currently doing on lunar energy ores?"

Jiang Fan continued to ask.

He has been responsible for the construction of the lunar space city on the moon for the past three years. The country has left the research on lunar energy ores to other scientific researchers.

Therefore, Jiang Fan didn’t know how far Long Guo’s research in this area had gone!

"In the past three years, our main research direction has been energy power generation technology. We only use the energy ore from the moon, which is enough for our entire Dragon Kingdom. Moreover, the energy ore from the moon is a light-pollution energy..."

No. 1 told Jiang Fan the general situation of Long Guo's research in the past three years.

Jiang Fan basically understood the situation.

In the past three years, the research directions of Longguo and Meimeiguo have been different.

In fact, it is not that the Dragon Kingdom does not want to conduct research at the same time. The main reason is that the Dragon Kingdom has given all its resources to Jiang Fan in order to build the lunar space city in the past three years.

In terms of funding, personnel, material resources, etc., there is no longer enough to support Longguo's comprehensive development and research of lunar energy ores.

Now that the construction of the Dragon Kingdom's lunar space city has been completed, the Dragon Kingdom has begun mining large quantities of energy ores on the moon.

Jiang Fan's work on the moon was basically completed, just as he was thinking about how to study lunar energy ores next.

The system suddenly rang in his mind.

It took three years for this voice to come out.

[System]: "Ding: The host has been detected to help Blue Star develop new energy ores, and related energy technologies will be rewarded."

When Jiang Fan heard this, he was immediately shocked.

Before he could react, system prompts kept ringing in his mind!

"Ding: Reward the host with super battery technology..."

"Ding: Reward host chip technology..."

"Ding: Reward the host with super thruster technology..."

"Ding: Reward the host with power generation technology..."

"..."

Jiang Fan was stunned when he heard every skill rewarded by the system.

With these technologies, it is equivalent to raising the entire existing technology of Blue Star to a whole level.

In the scientific research community on Blue Star, many scientists believe that the technological civilization of Blue Star can only be called a level 0.8 civilization in the universe, not even a level one civilization.

Jiang Fan now has the technologies rewarded by the system, and he believes that there should be no problem in upgrading Blue Star's civilization level to a first-level civilization.

These technologies will definitely make a qualitative leap in Longguo’s technology!

At this time, No. 1 saw that Jiang Fan had been silent and thought he was like this!

"Xiaofan, are you okay?"

When Jiang Fan heard No. 1 calling him, he hurriedly came out of his thoughts.

"Leader No. 1, I'm fine!"

"That's good!"

Number 1 was afraid that Jiang Fan would have any sequelae when he returned from the moon.

This was not just his imagination, but several cases of the sequelae of returning from the moon were discovered among this group of people from the Dragon Kingdom who came back.

And everyone's sequelae are different. Some people have edema all over the body that never goes away.

Some people's sequelae are mental anxiety, and they are easily frightened if there is any small abnormality around them.

"Xiaofan, if you feel unwell, you must get checked in time!"

"I know!"

Jiang Fan responded.

No. 1 saw that Jiang Fan spoke normally, so he felt relieved.

Jiang Fan is now an important scientific researcher in the Dragon Kingdom, and the country can no longer do without him.

If he falls, many of Dragon Kingdom's technological projects may be paralyzed.

Therefore, protecting Jiang Fan's life and safety is always the highest mission of the Dragon Kingdom at any time.
Chapter completed!
