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

Gu Zishu looked at the cheapest mutated green vine. He didn't know what it was before. Anyway, there were many pods on it now, which were thicker than the pods of green beans.

There are several thick and long roots on each section of the vine.

"What's the exploration value of this thing in one day?" Gu Zishu said curiously. He really couldn't imagine how this thing could explore the world.

"200."

"One exploration costs 200, and the total price is 5000. You can buy it, but the damage rate of this thing won't be as high as that of a small ant." Gu Zishu muttered.

"It's not 200 at a time, it's 24 for 200 hours. This is a tamed biological detector. You don't need to come over and click on it every two hours. It will automatically explore."

"..."

"It's only 200 a day. The little ant can do more than it." Gu Zishu looked at the price and felt that it didn't deserve the price. It was dozens of times more expensive than the little ant. How could he have the nerve to earn himself 200 exploration points in one day.

"Each detector will have its own differences. The characteristic of the green vine is that the pods it grows are edible, so its initial exploration value is 200, but if someone or a herbivore takes away its seeds, If it goes to other places, it can continue to sprout and grow, and humans may move with its plants, so its exploration value is determined by the speed of human movement." Ji Liangdan and Gu Zishu explained.

Gu Zishu:...

I should have told you earlier. I am not an unreasonable person. How could I not buy this thing just because of the price? After all, I have to buy a detector for the end of the world. Otherwise, who knows how big the end of the world will be and when I will be able to detect it. ah.

And it costs tens of thousands later. If this thing is so good, I must buy it. "If the damage rate is not so high, then I will buy it." Gu Zishu made the final confirmation.

"Don't worry, the green vine is most famous for its vitality. As long as it has roots, it can continue to sprout. If you put this thing on any plane, it will become a species invasion. But it is not afraid of the end of the world. It is not dangerous and can still form seeds. Food is the most popular thing." Ji Liang said calmly.

They don't dare to create things like green vines easily. In peacetime, it would be a complete species invasion, but in the end of the world, it is a different matter. After all, in the end of the world, normal species will become extinct and cannot grow.

Isn’t it something like green vine that is needed?

"Buy." Gu Zishu waved his hand.

Direct debit checkout.

"There is a bug in the system. There is no explore button." Gu Zishu opened his backpack after buying it, but after searching for a while, he couldn't see the explore button.

"This requires the host to plant it into the soil in person." Ji Liang explained.

……

Okay, I bought it all, and the system mall doesn’t have a 7-day no-reason return option, so I can only do this for now.

Gu Zishu opened another backpack and saw a thin mask lying inside.

He reached out and took it out, "Is this a biological gas mask?" Gu Zishu was confused as he held the mask. He believed it was a human skin mask, but it was really hard to believe that it was a gas mask.

"Of course, this is the latest technology gas mask. It can prevent all harmful objects from entering the host's body, providing comprehensive protection. It is also comfortable to wear and has a better experience." Ji Liang said proudly, and the whole potato was still beating on the light screen. After a moment, he was obviously very proud of what he had made.

"Really?" Gu Zishu seemed to believe it, holding a mask that was thinner than a facial mask and putting it directly on his face.

The smooth mask fit well. Gu Zishu laid it directly on his face, and immediately felt as if it was stuck. He even pulled it lightly, but it didn't come off.

When I got into the bathroom and took a look, I found that my face seemed to be covered with a thin veil, which did not delay my breathing or my ability to see.

It's quite magical, but with a veil on his face, it looks a bit abnormal no matter how you look at it.

"This one can protect me from any poison, right?

But doesn’t it look a little strange like this? "Gu Zishu turned his head and it was indeed on his face.

"The host presses the position between the eyebrows. There is a switch there. As long as it is turned on, it can be directly attached to the host. If it needs to be removed, the host can press it twice." Ji Liang reminded, and then an instruction manual appeared in Gu Zishu's mind. .

Sure enough, according to what Ji Liang said and the instructions, he clicked directly between the eyebrows. Suddenly a light flashed and the tulle suddenly became transparent.

Gu Zishu reached out and touched it, but there was nothing there, and there was no feeling on his face.

"This thing is really good." Gu Zishu couldn't help but admire.

"Of course, you can't take too many rewards." Ji Liang was very proud.

The little potato face on the screen is so raised that the facial features can no longer be seen.

"Okay, it seems that this equipment should be enough." Gu Zishu looked at the body armor he was wearing, so that he would not be like a little ant when he entered the apocalyptic plane.

"Remind the host that the exploration time has been upgraded to 1 hour each time. Currently, the host has three exploration opportunities. Please make reasonable arrangements and pay attention to life safety." Ji Liang looked at Gu Zishu, who was a little eager to try, and gave a final reminder.

"Okay, three chances, let's go to the primitive plane first." Gu Zishu decided not to come to such an exciting place yet. He just happened to entrust the little lion to the Dahe tribe. He hasn't been there in the past few days and doesn't know the situation. how's it going.

Just as he said, Gu Zishu bought 10 more backpacks, and then disappeared directly on the spot.

As soon as I entered the original plane, I was stunned by the heavy rain.

Gu Zishu was stunned for a moment and quickly took out the spare umbrella from his backpack.

"This is the end of the dry season." Gu Zishu looked around and saw that the mountains in the distance were still withered and yellow. No one was seen in the entire tribe, but some cheers could be heard.

Gu Zishu wanted to look where the sound was, but after taking two steps, he could hardly lift his feet.

It must have been raining for a while, and the soil on the ground was soaked soft. In these two steps, Gu Zishu's feet were three times bigger than before, and there were more than ten kilograms of mud on his shoes.

"I was careless. I forgot to prepare rain boots." Gu Zishu muttered, shaking the mud off his feet.

"Roar..." A wild beast's cry sounded behind Gu Zishu.

"Jiliang, why didn't you warn me that I was in danger?" Gu Zishu stiffened for a moment, and a knife immediately appeared in his hand, and his body quickly changed direction.

A majestic lion was standing not far away from him, shouting upward to the sky. After shouting, it stared straight at him and rushed towards him.

"Is there no danger?" Ji Liang was confused, and it didn't monitor.

Gu Zishu was speechless looking at the lion, which was only a little smaller than the tiger on the bus. Although he had practiced bodybuilding dance for a few days, you wouldn't think that you could deal with this big guy in front of you, right?
