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

Now Mr. Long is nearly 70 years old. He looks much older, but he looks so mentally wrong.

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 got married and had children for the scientific research career of Long Kingdom.

He usually lives alone.

When he first retired, he felt extremely lonely inside.

He has always lived in Longsheng University, and many people usually come to visit him.

But he felt empty-handed in his heart. Later, he couldn't rest, so he found the principal and said he wanted to go back to class.

But the principal was worried that his body would not be able to bear it, but the stubborn old man Long insisted on substitute.

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

In fact, Long Lai's idea is very simple, he wants to pass on his life experience to these young people, which can be regarded as the final contribution to the country.

"Teacher, you also teach classes. Can your body get rid of it?"

Jiang Fan was 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..."

Old Long said happily.

"Grandpa Long, you are young 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 that in the future, he would definitely ask Mr. Long to be his witness to marry him.

Unexpectedly, several years have passed, and Mr. Long has always remembered this incident.

Jiang Fan was still quite moved.

"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 this.

"Okay! Haha..."

Old Long has no children. He now completely regards Jiang Fan as his 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 returned to Lingzhou City.

They stayed at home until the sixth day.

The first senior manager of Long Kingdom called Jiang Fan, and Jiang Fan had to return to Kyoto.

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

"Xiaofan, are you resting like this these few days?"

No. 1 asked at Jiang Fan with a smile.

"Well enough!"

Jiang Fan replied with a smile.

The two then exchanged a few more greetings, and Jiang Fan asked No. 1.

"Leader No. 1, what happened? You are so anxious to find me."

"Yes!"

No. 1's expression then became serious.

"According to reliable information, Beautiful Country has developed a super battery through lunar energy ore."

“Super battery?”

Jiang Fan was a little surprised!

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

Jiang Fan asked.

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

“10 times?”

Jiang Fan was not very surprised after hearing this.

He is very clear about the energy contained in lunar energy ores.

"What research does our Long Kingdom have on lunar energy ore at present?"

Jiang Fan continued to ask.

For the past three years, he has been responsible for the construction of the Moon Space City on the Moon. The country has handed over the research on lunar energy ore to other scientific researchers.

Therefore, Jiang Fan did not know how far the Long Kingdom had studied in this regard!

"In the past three years, our main research direction is energy power generation technology. The use of the lunar energy ore alone is enough for our entire Long Kingdom to use. Moreover, the lunar energy ore is a light pollution energy..."

No. 1 told Jiang Fan about the general situation of Long Kingdom’s research over the past three years.

Jiang Fan basically understood the situation.

The research directions of Long Kingdom and Beautiful Kingdom in the past three years are different.

In fact, the Long Kingdom did not want to conduct research at the same time. It was mainly because the Long Kingdom gave all the resources to Jiang Fan in order to build the Moon Space City in the past three years.

In terms of funding, personnel, material resources, etc., there is no longer enough support for the comprehensive development and research of lunar energy ore in Longguo.

Now that the construction of the Moon Space City of the Dragon Kingdom has been completed, the Dragon Kingdom has begun to mine a large amount of energy ore on the moon.

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

The system suddenly rang in his mind.

This sound was separated by three years.

【System】: "Ding: It was detected that the host helped Blue Star develop new energy ore and rewarded related energy technologies."

When Jiang Fan heard this, he was shocked.

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

"Ding: Reward the host superbattery technology..."

"Ding: Reward the host chip technology..."

"Ding: Reward the host superthruster technology..."

"Ding: Reward the host's power generation technology..."

“…”

Jiang Fan was shocked and stunned when he heard the techniques rewarded by the system.

With these technologies, it is equivalent to upgrading the entire Blue Star existing technology to a full level.

In the scientific research community of Blue Star, many scientists believe that Blue Star technological civilization can only be called a level 0.8 civilization in the universe, but is less than a level 1 civilization.

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

These technologies can definitely make the technology of Longguo a qualitative leap!

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 call him, he hurriedly came out of his thoughts.

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

"That's good!"

No. 1 was afraid that Jiang Fan would leave any sequelae after returning from the moon.

This was not his random thought, but among the people of Long who came back, several sequelae were discovered.

Moreover, everyone's sequelae are different, some of which are swelling all over the body and can't go away.

Some people have mental anxiety and are prone to frightening if they have a small abnormality around them.

"Xiaofan, if you are unwell, you must check it in time!"

"I know!"

Jiang Fan responded.

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

Jiang Fan is now an important scientific researcher in the Long Kingdom, and the country is unable to live without him.

If he falls, many scientific and technological projects in Long Country will probably be paralyzed.

Therefore, no matter when, protecting Jiang Fan's life safety will always be the highest mission of the Dragon Kingdom.
Chapter completed!
