In the basement of the Song Kee food stall, in that secret garage.

A long wire was connected from the knife switch, extending all the way to the green space-time channel, and was making the final charge for the space-time channel before it crossed over.

Taking advantage of this period, the period is almost more than three hours of free time.

Song Yong took an inventory in his hand and carried out the last inventory of materials before crossing over......

By this time of the day, it was the fourth day of his return to the modern plane.

And the reason why he was delayed for an extra day than usual was that Song Yong spent an extra day on procurement in order to bring some more suitable materials to the plane of the primitive era.

After nearly a year, the changes that Song Yong brought to the Gray Rabbit Tribe can be said to be huge.

The Gray Rabbit tribe in the primordial era is now capable of making salt, burning pottery, and forging iron.

Even later, when the sown grains are harvested, they will be able to make wine, and they will be able to have steamed buns and steamed buns.

In terms of clothes, I can also weave the worst kind of linen.

Based on the above changes, today's Gray Rabbit tribe is completely a self-sufficient tribe.

Therefore, compared to the beginning, no matter what he brought with him, it could be regarded as the material that the tribe urgently needed, and now when Song Yong purchased it again, he found that it was necessary to make some changes to what he needed to bring with him.

After taking a morning out, Song Yong sat at his desk and planned about it.

After he almost bit the tip of a poor ballpoint pen, Song Yong drew up this list of supplies at hand.

In this long list, it goes something like this:

The first category of materials is that the goods went to a scrap shop, and bought a bunch of tattered things from the scrap shop.

The price is affordable, fifty yuan for an optional shared bicycle, and he loaded back as many as ten in one go.

This thing looks simple, just two wheels and a few parts, but with the current tech tree of the Gray Rabbit tribe, there is no way to make it for a long time.

Not to mention anything else, just those rubber tires that don't need to be inflated have a technological content that they can't imagine.

Perhaps, in the same way as if you keep bringing things over, maybe in a few decades, the small workshop of the Gray Rabbit tribe can knock out such a car.

In the scrap shop, Song Yong also spent 60 yuan to buy two scrap car tires, which were pulled back with those shared bicycles.

Seeing that there are still two months to go, the winter of the primordial plane is coming.

But at this time, the natives under their command are still barefoot, that is, after the snow falls, they will wrap a little animal skin when they go out.

In other words, there is no comfort at all, and the performance of waterproofing and warmth is really not very dripping.

It's not that he is reluctant to buy some shoes in the past, but Song Yong has taken one thing into account:

To the extent that those primitive people and natives can toss, there is still a huge amount of activity, even if you buy some old-fashioned rubber soles to untie * shoes in the past, it is estimated that they will be scrapped in two months.

But after seeing these old tires, Song Yong remembered the tire slippers handmade by the black uncles he saw in the news.

Immediately, I still felt that this kind of handmade rubber slippers were more suitable.

Didn't you read what it said on the news: many black uncles are looking forward to having a pair of rubber shoes like this, because they can be worn for a lifetime......

The second category of materials is sugar, which satisfies the appetite.

Including white sugar, rock sugar, lollipops, fruit candy and milk candy, Song Yong prepared a total of about 50 kilograms after walking around the wholesale market.

According to this amount, all the cubs of the Gray Rabbit tribe can be tossed out of tooth decay.

For up to now, the only way to obtain sugars in primitive times was to obtain a little honey in the mountains and forests at the risk of being crucified alive by the wild bees with the thickness of their toes.

Like the means of artificial sugar production, Song Yong has not even grown sugar beets and sugarcane, how can he obtain them.

Therefore, for the Gray Rabbit tribe and the indigenous people of the entire southwest region to be able to get enough happiness from sweets, for a long time to come.

Sugar, an irreplaceable necessity, can only be imported from the modern plane.

The third category is velvet stretch leggings.

After having a pickup truck with a cargo box, this time Song Yong crossed over, but he was ready to bring over four hundred and thirty-two pairs of leggings at one time.

The reason for the emergence of such a number with zero and whole number.

It was Song Yong who completely emptied the inventory of the online store, and in addition, Song Yong also placed a large order of 1,000 pieces.

Just by clearing the inventory, the online store owner was almost fainted with joy.

It's not easy, and the large amount of money that was pressed on these tattered goods can be regarded as being successfully revitalized.

But the problem is that when the outlet owner was ecstatic and saw the subsequent large order, he was shocked again.

Could it be that this kind of brightly colored leggings has become secretly popular?

And should he seize this business opportunity and get a new product?

In fact, Song Yong's large order of 1,000 pairs of leggings was actually made for the arrival of next spring.

Because next spring, it will be the time to give the slaves the official status of the tribe in his promise.

And the leggings have long become a status symbol for the official members of the tribe, and after becoming an official member, they must be issued.

At the same time, Song Yong, the current official member of the tribe, also plans to give each of them a new pair of leggings, which they will use to change and wash.

After all, when he touched the barren one last time, he would leave a lot of oil stains on his hands, and even the leggings that could faint Erha had caused too much psychological shadow to him.

The fourth category is explosion-proof helmets purchased from sports stores.

Today, the total amount of iron produced in the earthen blast furnace of the Gray Rabbit tribe in a month should be in the hundreds of thousands of catties, that is, about six or seven tons, according to Song Yong's estimates.

Even the tools and weapons forged from this kind of iron are certainly not as good as their counterparts in the modern plane.

However, Song Yong still felt that in terms of weapons and tools, the number of inputs to the primordial plane in the future could be greatly reduced.

For this reason, he brought all the remaining strengthened hunting bows with him this time, as well as a hundred explosion-proof helmets.

The main thing is that he thinks that the armor has leather armor inlaid with iron plates, which is barely enough.

The only thing that the quality of the primitive era is not up to par, or it is not easy to use at all, is the iron helmet built by the Gray Rabbit tribe.

But if you want to have enough defense under the attack of the fierce primitive natives, you can only have a thick one to be effective.

In that case, an iron lump of at least ten pounds is put on the head, and if it takes a little longer, do you want the neck?

Although some tribes are already holding all kinds of beast skulls and using them to make helmets.

But for such a thing with poor defense, Song Yong really had the intention to look down on it, it was better to bring it from the modern plane, which was both light and strong.

All of the above stuff almost filled the entire Great Wall cannon.

In the end, looking at the only remaining vacant seat for the co-pilot, Song Yong didn't think about wasting it, he hurriedly returned to the kitchen and took all the three boxes of instant noodles inside.

Mainly compared to those broths, Song Yong would rather come to play instant noodles every morning.

At the same time, he saw a large plastic bag of small snacks at the bar, and he didn't know if the female ticket bought it for him to quit smoking, or the stick for Xiaolin.

In short, Song Yong also took it away......
