In order to solve the problem caused by street lights in the base, the top management of the base held a special meeting.

Not to mention the useless points, the most discussed issue is whether Su Yan can bring back lighting energy from the interstellar plane.

Yes, it’s very expensive.

There are energy stones and artificial suns in the interstellar plane, but they are very expensive.

I don't know if energy stones are so expensive because they have passed through the planes. In short, for a family like Su Yan, it doesn't cost a penny to use it. But if it is used for lighting the entire base, according to the gold price mentioned above, hundreds of kilograms of gold will be consumed a day.

The artificial sun is even more expensive, the price is far higher than that of a spacecraft that can carry 100,000 people.

The meeting on lighting was a lonely one.

People who have cars can no longer drive to go to work. For example, the senior executives of the Sheng, Qin, Zhou and other bases can only take air transport from the S area to the office building to go to get off work, flying from the roof of their own building to the roof of the office building.

In order to facilitate Chief Sheng and Mr. Qin's travel, Su Yan equipped each of the two chiefs with a plane.

Because of the polar night, Su Yan's "Everything Can Be Shopped" is also open on time.

It would be useless if the store was open from 8 am to 8 pm as before. She didn't have many ordinary goods to sell and could only limit purchases. For luxury goods such as furniture and appliances, she wouldn't be able to complete an order for several days.

We have decided to open for two hours every day from 2pm to 4pm. We are so capricious.

There are nine children. The oldest, Yingzi, is now fifteen years old. Qiyou and Daming are also thirteen years old. The youngest, Zeng Chengcheng, was almost six years old when he was picked up by Zhang Yuan. He is now eight years old.

The store is opened for two hours every day, and there are three people in a shift. In this way, Yingzi and the others are a bit idle. After all, Luo Fuan and Zhang Yuan sometimes take them out for special training every other day or sometimes every two or three days.

Su Yan thought, in terms of fighting power, Zeng Chengcheng, who was already eight years old, could knock down an ordinary adult. Yingzi, Qiyou, and Daming, the three could fight her back and forth.

Then, let's focus on their liberal arts classes.

She goes to the office building in the morning and takes a break after lunch. So, she can let Yingzi and others come to her house for classes from 2pm to 5pm.

Yingziji has taught Daming and the others all the primary school knowledge. Of course, it is impossible to teach them systematically. They have to teach Chinese and mathematics. The youngest, Zeng Chengcheng, has also finished primary school in a hurry. Now I can teach them junior high school courses.

Su Yan told the old lady her idea, and the old lady agreed with both hands.

"You don't have to teach me. I taught Xiao Rui and Xiao Wei in the morning, and I can teach those kids during my lunch break. Leave this to me."

"Grandma, are you addicted to being a teacher?"

"I eat and drink well now, and I am in good health. These children will be your right-hand men in the future. I am happy to do more. I will educate you and keep an eye on you."

Su Yan did what she said. She called Yingzi and asked them to come over, and then quickly found the junior high school teacher.

Fortunately, the books had been classified by Su Qing and stored in a room in the space courtyard, otherwise it would be difficult for her to find them.

Yingzi and the others arrived very quickly.

"Sister Su, Grandma Sheng, we are here!"

The six voices sounded quite uniform, worthy of being the team members managed by Luo Fuan's military commander.

The old lady was quick and had asked Su Qing to move the dining table. She put a blackboard in the dining room, with three long tables and six folding chairs, so that two people could share one table.

"Children, how about Grandma Sheng being your teacher?"

Several "yes, yeah~"

Yingzi matured early, and after more than three decades of growth, she spoke like an adult at the age of fifteen. "It is a blessing for us to be taught by Grandma Sheng in person in three lifetimes!"

"It's not three lives, it's eighteen lives!" Qiyou was even more exaggerated, speaking with actions and little expressions. Well, he is a social hero.

The old lady said with a smile, "Come and sit down, listen to your sister Su. You are all smart kids. I will teach you quickly, and you can go back and digest it slowly. If you don't understand something, write it down and ask me the next day. There are three of you who need to watch the store every day, so I will give you a class every day, and you will be responsible for teaching the three people who watch the store at night. Can you do it?"

“I can do it!”

"Okay, then sit down and let the class begin."

Six hands raised high.

Su Yan had nothing to do next to her, so she pulled a chair and sat down to watch the old lady give a lecture.

The old lady was very patient and professional when she taught. Her speech was neither fast nor slow, giving people a very friendly feeling. She had to admit that she was not as good as the old lady.
