CH 72.2

What was more interesting was that Chu Guang found that his genetic sequence not only could be leveled up through basic exercise, but could also accumulate a small amount of development progress when leading the players to fight.

This unique way of evolution made Chu Guang very curious.

However, he was currently unable to record the progress of genetic sequence development in real time, so he could only do in-depth research when conditions were available in the future.

After stopping and moving along the way, they bypassed the inaccessible ruins and finally arrived at the destination before half past nine.

Outside Brown Farm.

When Chu Guang and his party arrived near the gate, they saw a strong man carrying a shotgun, leading a weak slave out of the wall.

When they saw each other, Chu Guang was calm, but the other side was nervous.

After seeing the exoskeleton on Chu Guang's body and the slightly exaggerated hammer behind him, the strong man subconsciously touched the shotgun behind him.

"We are passing traders, don't be nervous."

"Which trader would pass here at this time- Huh? It’s you."

Standing on the wall, Liu Zhengyue was dazed. The gun barrel that had just been shifted out was retracted again. He stared straight at the exoskeleton and hammer on Chu Guang's body—and the blue coat underneath the exoskeleton.

He clearly remembered that this guy was not dressed like this the last time he came here.

"Yes, it's me." Chu Guang smiled faintly, and shouted to him, "We need food, steel and copper."

"What do you have?"

Liu Zhengyue stared at the group of people outside the wall vigilantly, glancing back and forth on their equipment, a little apprehensive.

This group was obviously much stronger than when they came last time.

In principle, this was not a good time to do business. Winter came much earlier than usual this year, so they had to keep some grain for the winter. In addition, they had to prepare some surplus to prevent the marauders from raiding them.

Marauders from the north would come here from time to time. Although the farm was not without guns, no one wanted to risk fighting those people.

If they decided to harass them during harvest season in spring, the loss would not only be the grain of the tribute.

However……

The guns those people were carrying made him think carefully about the risk of rejection.

Chu Guang didn't speak, but walked to the front of the caravan. He opened the curtain, took out a sack from it, and tore the rope tied to it.

Liu Zhengyue's eyes narrowed, trying to see more clearly.

"This is……"

"High-purity magnesium ammonium phosphate, if you don't understand it, you can understand it as struvite. In short, it is a high-quality fertilizer." Chu Guang looked up at Liu Zhengyue on the wall, his tone was slightly unhappy, "Can you come down? Talking like this is very tiring.”

"Wait for me for a while... I have to ask my master for instructions."

After dropping this sentence, Liu Zhengyue disappeared on the wall, but it didn't take long before he led a slave out and reappeared at the front gate.

"My dear old friend... you have changed quite a lot."

"I got rich recently."

"Are you really nomads?" Liu Zhengyue stared straight at the blue coat under Chu Guang's exoskeleton, obviously not so sure of his judgment.

"Is that important?" Chu Guang said with a faint smile, "Don’t worry, I found this coat from a ruin."

Seeing that Chu Guang didn't intend to reveal more, Liu Zhengyue stopped asking questions, but looked at the bag of fertilizer.

"I need to inspect the goods."

This was a reasonable request, and Chu Guang nodded.

"Please."

The inspection method was the same as last time. Liu Zhengyue kicked the slave next to him and pointed to the bag.

The slave stepped forward, stretched out his index finger and wiped it in the bag. He then put his finger in his mouth and licked it.

"It's struvite."

Hearing these words, Liu Zhengyue showed a smile on his face.

Although he didn't know where this group of people got these good things from, these things were really what they needed.

After the feces of livestock and humans were heated, although it was also a kind of fertilizer, the nitrogen content was not enough, and its overall fertility was obviously not as good as the struvite that had been deposited and washed by rain.

Often, a handful of bird droppings was worth a large bucket of cow droppings. If the latter was used, it must be mixed with urea and sprinkled together.

Brown Farm itself was unable to produce high-quality urea in large quantities. Direct use of urine would not only burn the roots, but also easily cause soil compaction when mixed with manure.

Therefore, they often imported synthetic and organic fertilizers from Boulder City or Red River Town and mixed them with fermented manure.

This was true not only in the Brown Farm, but in all the survivor camps around the entire Qingquan City area.

"Name your price!"

"We only brought 300 kilograms. If you can give me a reasonable price, we can still cooperate in the future."

666 square meters of land would require about 10-50 kilograms of fertilizer, which could not be generalized according to the crops, soil conditions, fertilizer types, and expected harvest.

Judging from the map before the war, the area of ​​the entire farm was not large, roughly 48,000 square meters to 66,000 square meters of arable land, which was equivalent to 7~9 standard football fields.

Of course, it did not rule out that they were engaged in three-dimensional agriculture and indoor planting. After all, similar technologies were not uncommon before the war.

Chu Guang couldn't guess their needs and simply let them quote their own prices.

After hesitating for a moment, Liu Zhengyue said tentatively.

"How about 300 kilograms... for 2 tons of green wheat?"

Upon hearing this number, Chu Guang couldn't help feeling lucky in his heart.

Fortunately, he didn’t name his price first.

The wholesale price ratio he found on the Internet on the earth was almost 1:5, and what he expected was about 1:6~7.

It now appeared that prices in the parallel world could be said to have no reference value at all.

Chu Guang looked at him and said, "The minimum is 5 tons."

"5 tons?! This is impossible," Liu Zhengyue exclaimed. "Our output per 666 square meters of land is only 25 kilograms of green wheat."

"That's because you didn't use our fertilizer. It will be 500 kilograms from next year onwards."

The yield of this mutant crop is really bad...

Speaking of which, it would be great if we could get the pre-war seed bank.

For the standard wheat, the output per 666 square meters of land in the parallel world was at least 300 kilograms. It was not a problem if it was higher than 500 kilograms, but it was definitely bragging if it was more than 5000 kilograms.

Chu Guang thought in his heart, ‘I don’t know if shelter 404 has any seed banks, but there should always be some seed banks in those normal shelters, right?’

‘I wonder if it is because of the time or the weather that the pre-war crops did not become popular on the wasteland.’

‘Or is it just in this area?’

"Are you dreaming? Yield 500 kilograms per 666 square meters?" Liu Zhengyue stared with big eyes and shook his head. "My friend, if you are really sincere, 3 tons...This is the bottom line I can accept. We have a stable supply. Do you think your struvite stone is irreplaceable?"

"No, but it is definitely the most cost-effective. I don't think other people will sell this to you cheaply after traveling a long distance," Chu Guang said while looking at him. “1 kilogram for 12 kilograms of wheat, this is my biggest concession for the sake of the early winter. Next year we will also supply this stuff in large quantities. If you can't accept the price, I'd rather go back the same way and sell it to the dealers passing by."

The struvite on the shore of Linghu Lake was scattered in the shallows on the south side and extended to the east side. The reserves were not rich, but there were definitely quite a lot.

Chu Guang didn't know why these survivors didn't find this geomantic treasure, but in any case, it belonged to him now.

Liu Zhengyue hesitated for a while, and finally nodded.

"Okay, you better not lie to me... Next spring, we will need 3 tons of struvite, which will be used during the planting season. Where are you from? Qingquan City or the surrounding area? If it is not far away, we can pick up the goods."

"It's not necessary. When this winter passes, we will naturally deliver the goods."

Chu Guang smiled and stretched out his right hand.

“It was a pleasure doing business."

Although feeling distressed, Liu Zhengyue squeezed out a smile and held Chu Guang’s outstretched hand.

"Likewise...."
