The nitrate soil in the toilet, old houses, natural caves... Whenever there is nitrate soil, there must be water first, and the environment must be ventilated, alkaline earth, ammonia, etc. I have raised fish in my memory, learned about the common sense of purifying the water quality of a fish tank, and knew that the saltpeter in the nitrate soil is nitrate bacteria.

If nitrifying bacteria like oxygen, try every means to blow air into the water, use windmills, and cattle and horses. In short, you use linkage gears to drive the bellows to blow into the water, build houses, pools, and blow blow into septic tanks, day and night.

The saltpeter farm in the ranch creates as suitable environment as possible for nitrifying bacteria. But I don’t know what went wrong. Although there is also saltpeter production, I can get three or five kilograms every day, but how useful is this?

The Song Dynasty bans sales, and the Liao Dynasty will follow closely. It is difficult to produce saltpeter in the high temperature and rainy areas in the Southeast Asia...

After Su Mei left, Cai Hua lay alone on the bed and tossed and turned, but there was no good way. He didn't fall asleep until dawn.

December of the eighth year of Zhenghe was the coldest season in northern Song and Liao, but it was a hot summer on Zhennan Island. Perhaps it was too late last night, and everyone got up late. When Su Mei saw her son's legs were skewed and her whole bed was in a mess. She quietly watched her son buried in the bedding for a long time, she gently closed the door and strictly prohibited others from disturbing her son's rest.

The trauma in the chest left the root of the disease. Even in midsummer, Cai Yan had to cover his humiliation on his chest. When he woke up, the blazing sunlight had already penetrated into the room.

Sitting on the bed for a while, Cai Yan wiped the sweat off his face very much, and then he jumped out of the bed in his cow-nosed pants as usual, and opened the door with the insult.

"Uncle Huzi?"

As soon as I opened the door, I saw Huzi standing outside the door. I was stunned at first, then smiled bitterly and sighed.

"Uncle Huzi also learned about what happened last night?"

Hu Zi nodded and said, "I got the news of seventeen last night."

Hu Zi took the quilt from Cai Huang and said, "There are too many people in Song Dynasty? Fortunately, our ship has not returned to Ma Yi Kingdom yet? It has not caused much damage. I just saw it at 17 o'clock? I mentioned this matter."

"Oh?" Cai Huang was stunned? Then he pounced on the hanging quilt with a stick twice, and smiled and said, "Seventeen, they won't be dissatisfied with anything, right?"

Hu Zi shook his head and said, "We will do whatever the young master says? No one will be dissatisfied, but the brothers privately think that the young master is too good to the people of Song?"

"Haha..." Cai Yan leaned on the wooden stick in the corner of the wall? He greeted Hu Zi and sat in the rattan chair. He smiled and said, "I still said that I have no dissatisfaction or complaints?"

“…”

"It is normal to be dissatisfied and complaints, but it is abnormal if not, but we should know what is the primary and secondary."

Cai Yan was lying in a rattan chair? His legs were slightly apart and he looked up at the green sky. He sighed: "When my grandfather was willing to die, why did Master Anon leave with Uncle Huzi? Why did he return to the village?"

"Because... people's hearts are dispersed."

...

Hu Zi was silent for a moment. He had experienced what happened ten years ago and knew very well what happened back then...

"The Hailong Gang is divided into two, Liuqiu's old village on the island? The Hairui Business that has landed. Although it still looks one, everyone knows that the Hailong Gang no longer exists."

"Wallower used the Liao Kingdom and forced the Song Kingdom to release the Liao Kingdom? It also forced the Hairui merchants to leave the Song Kingdom and had to return to the sea."

Cai Yan sighed, "It is easy to go from frugality to extravagance? It is difficult to go from extravagance to frugality. Just like the Song people who were not satisfied with their usual money last night? The Hairui Business Company also faced the same problem? It's just that the Song people who were connected with us last night spent a short time together, and the problems emerged earlier."

Hu Zi said as if he was aware: "What does the young master mean? Or... the whole world?"

Cai Yan was silent for a moment, nodded slightly and said, "That's it. Yan'er first forced the old village to come to the exile site of Zhennan Island, and then forced the Hairui business to leave the blooming state of Song. If it were Uncle Hu Zi, would Uncle Hu Zi be satisfied?"

Hu Zi shook his head slightly, and it would be fine to enter the prosperous Hangzhou from the poor village, but if he went from Hangzhou to Zhennan Island where birds could not shit...

"It is easy to go from frugality to extravagance, but it is difficult to go from extravagance to frugality..."

Cai Huang sighed deeply.

"If you can re-plug the discrete teams, the crisis of life and death is only one aspect. If there is no greater benefit in front of you, even if you barely combine for the time being, you will only die a day or two later."

"And at this time, when the Liao Kingdom was about to face a disaster, it also gave us more opportunities and gave everyone the opportunity to return to the local land."

Hu Zi was Cai Yan's personal follower. He could know something that others didn't know. After a moment of silence, he nodded and said, "As the young master said, the Liao Kingdom and the female savages fought for decades, just like the old village and the mountain barbarians who fought for ten years. The female savages seized the Liao Kingdom Tokyo and besieged the old village with the Guyue barbarians. If there was no Hairui merchant, they would always transport soldiers and supplies, and Liuqiu's old village might have no longer existed."

"The Liao Kingdom is weak like the tribe who trapped the old village, and the Nao Ren is like the ancient Yue barbarians in the mountains and forests. Hu Zi can understand the young master's support for the Liao Kingdom, just like the ancient Yue barbarians who fought with the old village for ten years. After the young master agreed to marry Miss Lunong, after reconciling with them, the original enemy became ours. The prince-in-law of Shu Kingdom is Miss Lunong. Once the Liao Kingdom is defeated and destroyed, we can naturally lead troops into Liao Kingdom and turn Liao Kingdom into Liuqiu County... But what does this have to do with Song Kingdom? Does Song Kingdom want Yanyun land? Liuqiu County?"

Cai Yan looked at the man beside him in amazement. He never thought that he would say this, who had always been dull and silent. Seeing that Cai Yan's eyes were strange, Hu Zi smiled bitterly.

"I only realized after listening to the words of Seventeen and others."

Cai Wang couldn't help but smile and nodded slightly, "Uncle Huzi said it well. Although Liuqiu County is not worth mentioning compared to Liao Kingdom, as Huzi said, Liuqiu County and Liao Kingdom, Lunong and Niu Niu Niu, Gu Yue Barbarians and Female Nao Savage... They can indeed compare and understand."

"The situation in Liao Kingdom is relatively serious. Since signing the "Tanyuan Alliance" with Song Kingdom, the main force of Liao Kingdom has not been in the south, but in the mountains and forests of Liaodong where grass valleys can be defeated. In Zhongjing, Shangjing grasslands, Yezihe, and Huanglongfu, although Liao Kingdom still has some strength, most of the elite lost."

"One rises and one falls, one prospers and one declines, the Liao Kingdom has lost its ten-year national destiny, the struggle for national destiny, and the fighting for offense and defense."

"The defeat in the war and half of the elite are nothing. These are nothing. As long as the passes are sealed, as long as the internal stability and the top and bottom are united, it is nothing. The reason why the Liao Kingdom lost ten years of national destiny is that the Liao Kingdom needs to use ten years of cultivation and rest, and need to prepare military and horses. Just like the four emperors of the Han Dynasty accumulated strength, the Wu Emperor would be able to suppress the Huns in one fell swoop."

Cai Huang shook his head gently and sighed: "It's a pity that the Liao Kingdom has accumulated a lot of problems. First, the royal family fought internally and became chaotic, and the poor people rose up. There were internal and external difficulties. Song and Jin joined forces to attack north and south, and the destruction of the country was inevitable."

Hu Zi nodded slightly, knowing that the elders in the clan were all aware of the potential dangers of the Liao Kingdom, and knowing that the young master lying in the rattan chair convinced Hai Rui's merchant to return to the sea. The more he did this, the more he was confused about his attitude towards Song Kingdom.
