"Whew!"

After calming down, Jiang Heng decided to go to the vegetable market in the town to have a look, Yuzhu Village was still very close to the town, only two or three kilometers away.

But before he goes, he has to see if the old electric car at home is still useful, and by the way, decide what to buy.

With a capacity of only ten catties, the biggest effect is naturally the seed, but now the primitive world is about to enter the autumn, and the winter there is particularly cold, and most of the crops may freeze to death.

So Jiang Heng's idea was that part of the cold-tolerant seeds went to test the water, such as wheat, barley, coriander, radish, etc.

A high-yielding crop like sweet potatoes is no longer available this year, so you can wait until next year to try again.

In addition to these crop seeds, Jiang Heng thought about it and prepared tools to go over, a few iron tools, a little poison was already the limit, although he knew that human beings now have a lot of very light but extremely sharp special materials, similar to carbon fiber.

But those were too far away from him to collect them in a day, so it was better to buy a few unluring steel knives and poisons.

And then spend the rest of the time browsing and storing knowledge, which is truly unlimited, and as long as the knowledge is sufficient, it can even replicate the human industry in the other world.

"No power!"

Jiang Heng glanced at the electric car that was running out of power, charged it, and then went to the bedroom with his notebook, and began to browse all kinds of knowledge, especially some ancient videos, some methods of finding edible plants in the wild, and so on.

In fact, he knew that none of his methods were scientific enough, and if there were scientists, he would definitely be able to bring the most suitable items with him through thorough consideration and research.

But there was no way, he wanted to monopolize this primitive world, and he didn't want to share it with anyone, even his parents and brothers.

So you can only follow your own way step by step.

If he can bring back extraordinary power in the future, he will think about other things.

Not only browsed on the computer, Jiang Heng also bought some books on the Internet, the fragmentation of knowledge on the Internet is too serious, and only books can be studied systematically.

These include the three sacred books, "The Barefoot Doctor's Handbook", "The Military and Civilian Military Training Manual", and "The Friend of Military and Civilian Talents".

These three books contain some useful knowledge that can help him spend time in the other world.

Looking at it, Jiang Heng suddenly had a whimsical idea: "Do you want me to simply go back with two pistols, so that I can kill the fierce beast and get the blood of the fierce beast?"

It's not too much to be afraid that the warriors of the Worm tribe will rush over. ”

Jiang Heng's eyes lit up, if he could get a pistol, he could definitely solve these problems in front of him.

But then he showed a helpless expression, this is the rabbit country, these things can't be obtained in a short time, at least go abroad.

That would be too troublesome, and it would be too late in time, and it would not mean that you can buy guns and ammunition if you go abroad.

Now there is only one way left, and that is to make a homemade earth bomb, but he only knows the general principle and has never made it.

I only know that one sulfur, two nitrates, three charcoal, and then sugar are powerful, and I don't know how to operate it at all.

But it doesn't matter, his best friend, Wang Zhou, is a chemistry genius and is still a graduate student.

Immediately, he sent a message to Wang Zhou: "Xiao Zhouzi, how to use the most common materials to make a powerful earth bomb." ”

After a while, Wang Zhou replied: "? ”

Wang Zhou: "What can't you kid think about?" Girlfriend robbed or? ”

Jiang Heng: "...... Don't get me wrong, I'm going to go to the wilderness, didn't I tell you before, I'm going to quit my job and travel around the world. Now that I've resigned, I'm asking about this in case I need it. ”

Wang Zhou: "Damn, I really resigned, I envy you kid, I will step on a horse and use my mentor as a cow and a horse for experiments, I am jealous." ”

……

After chatting for a while, Jiang Heng got a very perfect plan for making a soil bomb from Wang Zhou, in his words, as long as it is used well, an elephant can be easily killed.

The main thing is that the materials are common and easy to make.

He immediately wrote down all the details, and prepared to buy some materials for the primitive world later.

After reading the book for a few more hours, waiting for the car to almost run out, Jiang Heng rode out.

It was noon when he first returned, and it was already afternoon.

Riding a small motorcycle, walking on the coastal road is a special feeling.

The sea breeze is salty, constantly blowing Jiang Heng's hair, and the blue sea in the distance is also blown up by the sea breeze one after another blue peaks, and some snow peaks are brought on this peak from time to time, which is very beautiful.

Some of the fishing boats staggered towards the shore, looking as if they were walking in the mountains from a distance, and there was an indescribable silence in the midst of the hustle and bustle.

Soon Jiang Heng came to the town, because of the sea, it was full of seafood smells, and the most sold seafood was all kinds of seafood.

"Boss, let's have a bowl of seafood noodles, and I want to add five kinds of seafood."

Jiang Heng went to eat a bowl of seafood noodles first, and the noodles still had a familiar taste, unchanged for decades.

After eating, he went to the hardware store first, ready to buy some tools.

"What tools are you going to buy?"

The owner of the hardware store was a middle-aged man, and when he saw Jiang Heng coming in, he asked casually.

"Is there anything particularly sharp and light?" Jiang Heng asked.

"This ...... What are you going to do? The hardware store owner didn't know what Jiang Heng was going to do with it.

"Forget it, you can just get me the kind of blade you use for cutting, I want three boxes."

Jiang Heng pointed to the utility knife blade on the shelf and said.

This is the tool he has come up with at home, this blade is relatively light, but very sharp, and it should work well in another world.

Three boxes are almost fifteen tablets, less than half a catty.

"Okay, what more?"

The hardware store owner asked again.

"Two hand saws, two hatchetees."

Jiang Heng said again, he weighed it, a firewood knife is three catties, and a handsaw is two catties, which are not light, and it is estimated that he can only take one to the primitive world.

After buying these, he was ready to go to the seed store.

"Boss, do you have wheat, radish, peppers, and coriander seeds?"

Jiang Heng looked at the boss and asked, he didn't ask about the barley seeds, it is impossible to have them in the low-altitude areas along the coast, he has already bought them from the Internet.

"Both, how much do you want?"

The boss nodded and looked at Jiang Heng.

"Two catties of wheat seeds, two taels of others, and one catty of ammonium nitrate by the way."

Jiang Heng looked at the boss and said.

Soon the boss weighed him enough seeds and fertilizers, Jiang Heng took a look, and bought another bottle of highly toxic pesticides.

After turning to leave, he went to buy some other ingredients, and finally some ingredients and books, and then rode his little electric donkey home.
