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

But during the day, she found that things were different. Gu Zishu was still studying hard.

He looked at the book with a serious expression.

It seems that he is really stimulated now. Has he decided to change his mind and study hard? Zhang Cancan, who also has low grades, feels so panicked.

She looked at Gu Zishu writing furiously and taking notes, wondering if she should find someone to stimulate her, and seriously consider the feasibility of the matter.

Thinking about it later, if I fall out of love, I will probably be heartbroken. I will be even less in the mood to study, my grades will plummet, my life will be decadent, and it will be difficult for me to graduate in the end.

Thinking of this terrible result, Zhang Cancan immediately shook his head and shook away his terrible thoughts.

Fortunately, Gu Zishu only had the side effects of studying hard, but not the other side effects. Zhang Cancan had been observing her for a day and was not worried about her anymore.

This sister is stronger than her.

He had promised to study hard and retire after graduation, and Gu Zishu would certainly do it.

Besides, I have learned it once in my last life, and if I try it again, no matter how difficult it is, after the teacher's explanation and Gu Zishu's hard work, some difficult problems are no longer difficult.

After a day of study, Gu Zishu went to bed early in the evening. Tomorrow is Saturday. When the three days are up, the second dimension of the system will be opened.

Gu Zishu planned to go back to the rental house in the morning to get ready, and then directly enter the second dimension there for his first exploration.

The next day, Gu Zishu still managed to get up at 5 o'clock according to the alarm time.

It was quiet inside the dormitory, and someone had already gotten up to read.

Gu Zishu didn't interrupt. He washed up and rode towards the rental house.

In the end of the world, Gu Zishu guessed several situations, including high temperature, low temperature, flooding, and zombies.

Either way, it was hard. Gu Zishu didn't know what the situation was, but he had found everything he could use.

The backpack contained clothes, drinks, an inflatable boat, and iron rods.

Anyway, Gu Zishu prepared everything he could buy from the shops on the roadside.

After being equipped, Gu Zishu bought a large bag of vegetables from the vegetable market. He must prepare food, just in case, although he won't stay there for long.

When he got home, he started cooking. Of course, it wasn't just the food he bought, but also the food Gu Zishu got out of his backpack.

In one morning, Gu Zishu lost half of the tank of gas at home.

The neighbors at home around me were in pain and happiness.

What's painful is that you can't smell the fragrance and can't eat it. What's happy is that you can finally smell the fragrance that you haven't smelled for a long time.

Get ready and have lunch.

Gu Zishu opened the light screen and saw that the originally dark apocalyptic plane lit up.

"I'm glad to see the host again. Ji Liang will continue to serve you." A familiar voice sounded in Gu Zishu's mind.

Gu Zishu also discovered that there was a jumping stuck potato on the light screen.

"Jiliang, do you have an image?" Gu Zishu poked the little potato with his hand in surprise.

Little Potato suddenly moved his position.

"Host, please keep your distance, be careful, and don't touch my body." Xiaotuo said proudly with wide eyes.

The tone has also changed a bit from the previous Ji Liang.

"You live in my head, and you don't allow me to click on you through the screen. This double standard has no limit." Gu Zishu complained ruthlessly.

"There is no way. You can also live in my brain, but you don't have this function." Ji Liang said coolly.

……

This is a bit irritating.

Gu Zishu took a deep breath and said, "Jiliang, a new dimension has opened. Is there no reward?"

"In order to prevent the host from entering the apocalyptic plane and dying on the spot, the host is rewarded with a biological gas mask. It has been placed in the backpack, please check it yourself." Ji Liang was prepared. When Gu Zishu asked, the other party immediately answered.

"It's too stingy to reward you with just a mask!" Gu Zishu vomited and opened his backpack. The backpack was full of things. In the past three days, the detector couldn't detect it, so this time It's all parked inside the backpack.

Gu Zishu continued to release the detector first. After all, there are still many unexplored places in the original plane. The value of exploration is not in vain.

"By the way, Ji Liang, can these detectors be placed in the apocalyptic plane?" Gu Zishu suddenly thought of a question.

"No, the apocalyptic plane is different from other planes." Ji Liang replied affirmatively.

"Are there different explorers for each plane?" Gu Zishu put the detector out and curiously opened the exchange shop. Sure enough, there were some new species on it.

"Why didn't we have these before?" Gu Zishu looked curiously at something that looked very different.

"These are expensive and relatively aggressive. They are only suitable for the apocalyptic plane." Ji Liang explained.

Gu Zishu looked at the prices. The lowest ones were worth thousands of exploration points. If he had been broke before, he would definitely not be able to afford them.

The system can indeed do business.

"Then can I buy new ants or something and put them into the apocalyptic plane?"

"Yes, but the apocalyptic plane is very dangerous and the attrition rate is very high. I advise you to think about it carefully." Ji Liang reminded kindly.

"The loss rate is high?" Gu Zishu was a little curious about the loss rate, so he directly bought a junior exploration ant.

After being dropped into the apocalyptic plane, a small dot lit up on the originally dark plane.

The small bright spots moved forward, and suddenly there were several more small bright spots in the apocalyptic plane.

"Isn't it nothing? It's okay." Gu Zishu felt relieved. It was not as dangerous as he said.

Gu Zishu turned off the map.

"Reminder, the detector is damaged."

Before Gu Zishu opened his backpack to look at the rewards, he heard a reminder from the system.

Opening the map of the apocalyptic plane, sure enough, the little ants on it were gone.

It’s only been a minute!

Gu Zishu was shocked. He opened his backpack and saw the little ant's broken body, which was even more damaged than the last time.

All the claws were missing, the body was broken in half, and there were burn marks on it.

"It was bombed." Gu Zishu took a deep breath. The apocalyptic plane was so dangerous that not even an ant could survive. How long could he last on his own?

"I reminded you before." Ji Liang added.

Anyway, 300 exploration points are wasted.

Gu Zishu turned directly to the first page of the exchange store.

Looking at the strange things on it, Gu Zishu asked a question.

"By the way, why are there more plants on the detector?"

"It's the end of the world, so don't be so restricted in your thoughts. Nothing is impossible." Ji Liang said calmly.

Gu Zishu silently closed his mouth. As for the most expensive one, it’s better not to look at it. The humanoid detector Zombie King is okay. Gu Zishu really can’t imagine that if this thing is released, he will pick something up for him. No. One day I will open my backpack and there will be a few more people staying there.

Gu Zishu cast his gaze directly on the detector above.
