Reborn in the end of the world, I scavenged in the empty city and bought for free

In order to exchange for more rice and flour, Xu Hang began to purchase a large number of crystal cores from the supernatural groups within their own small circle. At first, he exchanged them according to the standard of 1500 C-level crystal cores. Later, when he raised the price to two thousand, still no one was willing to sell. In the end, he had to grit his teeth and decided to exchange them for ten kilograms of rice or flour.

In fact, he also had his own little calculations. Gu Tongwan gave him a C-grade crystal core in exchange for twenty kilograms of rice. He lowered the price in the group, so that after getting the crystal core, he could earn another ten kilograms of rice from Gu Tongwan.

However, the people in the group are not so easily fooled. They are reluctant to exchange ten kilograms of rice for a C-grade crystal core with good quality control. Especially for the psychics, the crystal core can be made into a good thing for upgrading potions. If it weren't for the temporary shortage of rice and flour in the base, these psychics would definitely not be willing to give up the crystal cores in their hands.

However, after a final round of bargaining, Xu Hang finally got five B-grade crystal cores and twenty C-grade crystal cores at the price of fifteen kilograms of rice or twenty kilograms of flour for one C-grade crystal core, and twenty kilograms of rice and ten kilograms of flour for one B-grade crystal core.

As a result, Xu Hang and his team only had less than one-third of the rice and flour left in their hands. The team members were a little worried that Xu Hang might take too big a risk. After all, they had to know that these rice and flour were obtained with great difficulty.

Xu Hang smiled and said it was no problem, but he was actually worried in his heart. He just wanted to exchange more food for his brothers. After all, the rice and flour exchanged last time only weighed about 20 kilograms per person. If they still couldn't hunt normally in the later stage, this amount of food would not last long.

Fortunately, Gu Tongwan gave him a reassurance, saying that as long as the crystal cores were above C-level, they could be collected, and if more B-level or even A-level crystal cores could be found, she could provide additional food.

Xu Hang could only smile bitterly and send a message, [The best we can get is the B-level crystal core. There are not many in the guild. The only two A-level crystal cores are in the hands of our president. They are extremely precious. As for other guilds, the situations are basically the same as ours. You should know that hunting A-level mutant beasts often requires at least a B-level hunting team to successfully kill them. Generally, small and medium-sized guilds will regard them as "treasures of the guild."

The second trading day was two days later, still at the same location. The rain on these two days was lighter than before. The rainy time was mainly concentrated in the noon and evening, and the rest of the time it was drizzling. Some people were brave enough to go out with plastic basins when it was drizzling, and some shops had already started trial operations.

This time, Xu Hang collected a total of twelve B-grade crystal cores and thirty-one C-grade crystal cores, which he exchanged for about twenty bags of thirty-kilogram rice and thirty bags of twenty-kilogram flour. In addition, as agreed upon before, Gu Tongwan generously took three previously processed mutant pig heads and thirty kilograms of meat, as well as some extra pig offal. There were a lot of these in the space, and they were troublesome to deal with. Since Xu Hang generously gave him more than a dozen D-grade crystal cores, a rough calculation showed that they were worth at least several thousand points, so Gu Tongwan simply gave him a few more things, as a favor to each other.

After everything was replaced, Gu Tongwan immediately went to deliver the goods to Cai Min.

The wanderer base where Cai Min was located did not have many crystal cores available. Cai Min used a lot of connections and finally got one B-grade crystal core and five C-grade crystal cores. This was also obtained by Cai Min's younger brother from an acquaintance in exchange for a lot of dehydrated vegetables and coarse noodles. If it weren't for trust in Gu Tongwan, Cai Min would not have been willing to take out all the spare food stored in the family at once.

The place where the two exchanged goods was the gas station halfway between the base and the wanderer base camp. This time, Cai Min came with her husband. The couple also drove a pickup truck, but there were black spots on the pickup truck where people had burned, and white marks of a special anti-corrosion coating on the tires. It was said that this anti-corrosion coating came from a black market organization and was very expensive. A barrel of one liter of the coating cost nearly one thousand points and was mainly used on tires and doors and windows.

Seeing Gu Tongwan starting to move things from the back of the car, Cai Min and his wife immediately stepped forward to help. In total, they gave the Cai family two bags of rice and three bags of flour. They also gave the Cai family some pig offal and some difficult-to-process parts, which totaled about 30 kilograms.

Cai Min was surprised and delighted when she saw the frozen meat, and asked quickly, "Xiao Gu, how can you be so embarrassed? The price you gave us was already very favorable, and the rice and flour you brought were all very good. We ate the two kilograms of rice you gave us last time and couldn't forget it. The taste is much better than meat. You don't know that the rice you buy outside now has a strange smell. The rice we grow over there is the same. But I heard that the rice eaten in the capital is different from ours. It seems that the rice in the granary in the capital was secretly moved. I don't know if it's true."

Gu Tongwan had actually heard of this statement, and had also asked Liao Yunyun privately. According to Liao Yunyun, the rice eaten by some of the dignitaries in the base was indeed airlifted from the capital, so what Cai Min said might not be groundless.

After this trip, all the crystal cores in Gu Tongwan's hand added up to just enough to upgrade the black soil. After she converted all the crystal cores into system points for upgrading, she entered the space as soon as possible.

Just after entering the space, the previous road suddenly became clear. On the left was a warehouse with rows of various supplies stacked on it.

There is a wide road in the middle. About 30 meters ahead, there is a ridge on the right. At this point, you can see that the area of ​​the land is a full acre, but in fact it looks larger. Half of the area has been planted with apples and pears. Judging from the size and color, it will take some time for them to mature.

There is about half an acre of land left, so you can consider planting some rice. Although the area is not too large, half an acre of land can produce more than a thousand kilograms of rice a year.

There were several hundred 50-kilogram bags of rice stored in the space before. When she checked the inventory today, there were only more than 240 bags left. In the past three years, she had not had many opportunities to cook by herself. A 50-kilogram bag of rice could last her several months, so the consumption was not great in three years. After exchanging more than 30 bags of rice for crystal cores this time, the inventory on hand is still sufficient. Not to mention anything else, she can achieve rice freedom in the next 50 years. But if she wants to trade rice and flour in the future, it is better to have more stock.

But this matter can be done slowly, and there is no need to rush in the near future.

Since there was still plenty of time, Gu Tongwan simply rolled up his sleeves and went directly to the farmland to work. In the past few years, he has been tidying up the orchard more often in the space. When he first went to the farmland, he had to slowly explore and experiment according to the various planting knowledge points on his mobile phone. From the beginning, he didn't even know when the apples were ripe, how much pesticide to use when there were pests, and then he could quickly drive away pests and apply fertilizers. These were all accumulated little by little through daily farming.

After working in the field for almost two hours, I sowed some Hami melon seeds on the other half acre of land. According to the current growth rate of the land, the Hami melons should be ripe in less than two months.

It was already past seven in the evening when Gu Tongwan came out of the space. He discovered that there were "dong dong dong" sounds coming from downstairs. It should be Yan Fan and the two dogs still training downstairs, but the two dogs just treated it as a game and were having a lot of fun.

Yan Fan has been practicing hard during this period. He gets up at six o'clock every morning to do morning meditation, as if this can exercise his mental strength. After breakfast, he starts to practice his supernatural powers. His practice method is also very simple. He uses a plastic bucket that is estimated to be about 25 liters in capacity, and directly condenses the water in the bucket into ice cubes, and calculates the time it takes to completely freeze a bucket of water.

I remember that at the beginning it took Yan Fan at least fifteen minutes to freeze a bucket of water. After a period of practice, Yan Fan has shortened the time to seven minutes, saving at least half the time compared to before.

Not only that, Yan Fan can now use two more ice cones at one time than before, totaling eighteen cones per pound. However, if he catalyzes all the ice cones at once, he will need at least half a minute to rest. If he is in battle, this half minute is enough for the opponent to take his life.

Therefore, Yan Fan is currently trying to find a way to shorten the time required for adjustment after each consumption of supernatural powers.

With the upgrading of the black soil in Gu Tongwan's space, on the 25th day of the acid rain, the long-lost sun finally appeared in the sky, and the acid rain came to an end. The Meteorological Bureau also reported the meteorological news about the cessation of acid rain that evening.

All the intact radios in the entire base were continuously repeating the news that the acid rain had ended.

However, this acid rain also left some buildings in the base in ruins, and traces of burning and corrosion could be seen everywhere on the streets.

However, since most of the buildings in the inner circle were originally built with special materials, the damage was not serious.

The nearly one-month acid rain period caused a total of 102 deaths in the base, more than 300 serious injuries, and thousands of minor injuries.

The outer circle temporary shelter has finally announced the end of its continued sheltering operations and will cease all operations from today. Thousands of people in the shelter must return to their original places of residence.

Some of those who returned to the shantytown felt powerless looking at the place that could no longer be called home. Some even sat on the ground and burst into tears. Although a home had been destroyed, at least the people were safe. The most important thing was to survive.

The post-disaster reconstruction work at the base is currently being carried out in succession, and a total of nearly 3,000 volunteers are being recruited for the entire base. However, these volunteers are mainly grassroots personnel from the outer circle. Volunteers who voluntarily sign up can receive two kilograms of rice or two kilograms of flour every day, and volunteers need to provide identity tags to verify their correct residential address. If they are found to be impersonating someone else, not only will they not receive the day's salary, they will also be forced to work for a week.

After this regulation came out, there were indeed fewer people in the base who claimed to be disaster victims and claimed supplies.

During this period, Gu Tongwan, through Cai Min's matchmaking, sold some of the supplies in the space to the wanderer base camp. However, she only sold about a hundred kilograms at a time, and there were about three transactions in total. And this time she didn't want crystal cores, but only points.

Although Cai Min lives in the Wanderer Base Camp, the Wanderer Base Camp actually has a close relationship with the Jiangcheng Base, and a unified points currency is used by default in several surrounding large bases.

The three transactions earned a total of 003 points. Later, when Cai Min sent a message saying that there were buyers who wanted to buy in large quantities, Gu Tongwan said that the supplies were sold out and she had no channels to purchase them. After asking several times and getting the same answer, she gradually gave up. \ud

There are now a total of 120,000 points in the space. Although this wealth is far more than 95% of the people in the base, she knows very well that these points are not enough to buy a house in the underground city.

On the 1,352nd day of the apocalypse, a bombshell news swept the entire base, even alarming the nearby wanderer base and black market base.

Currently, the dungeon is only open to residents in the inner circle, and the outer circle is expected to open in two weeks.

There are a total of eight entrance points in the inner circle of the dungeon, and letters are used to represent the names of each entrance point, from Gate A to Gate H. Currently, four entrances are open to the public. Each entrance is guarded by four B-level guards and twenty C-level guards. Not only that, the firepower is also equipped with heavy machine guns and fully automatic mechanical rifles.

The reason why so many people were mobilized at great length was because we were worried that when the dungeon was first opened, someone would cause trouble or use extreme means to enter the dungeon.

As for the outer circle, entrances are set up in each commercial center. Initially, there were eighteen entrances in the outer circle. Six of them will be open to the public, and the remaining twelve entrances will remain closed.

The opening time is set for January 1th, and each entrance is limited to 10 people, which means that only people will be allowed in on the first day.

The vast majority of these two thousand people are powerful people or their relatives, or members of confidential departments. Although Gu Tongwan really wants to enter, it is difficult to get in with her current identity, so she can only wait quietly for the inner circle open day for ordinary citizens next week.

Liao Yunyun joked that if she asked Chen Yanxi for help, she would be able to get in immediately tomorrow.

Gu Tongwan just smiled and said, "I have already repaid the favors I owe you. I can't always rely on others. I'm not in a hurry to get in anyway. Just wait patiently."

Liao Yunyun smiled, thinking that the two of them clearly seemed to have a good impression of each other, but one was reserved and the other was standing still. She didn't know if the two of them could succeed this year. Was she still waiting to attend the wedding?

A week later, Gu Tongwan's online application to enter the underground city was finally approved, and tomorrow morning he will be able to enter another human residence that the base spent two and a half years to build.
