Of course, if it hits a person's body, especially a martial artist who has cultivated hard skills, the defense of the surface skin and muscles is much stronger than that of a sandbag, and it will not penetrate, but the force will penetrate and destroy the internal organs.

The mystery of the half-step collapse fist lies in the fact that the bent legs can exert force in two consecutive stages, and of course, it is also necessary to use the will to control the contraction and expansion of the muscles of the whole body.

This process is very long to say, but the practitioner should complete the second stage of power as quickly as possible, the faster the better, it is best to be able to exert force twice in an instant, so that the effect of breaking the defense of the dark energy will be better, and there will be no embarrassment of the enemy suddenly dodging and dodging in the interval between your second force.

Of course, if a cultivator's internal practice is extremely profound, and he has achieved perfect control over the muscles of the whole body, can quickly control the contraction and expansion of the muscles anytime and anywhere, and can explode the second stage of dark energy in various postures, then you have achieved the transformation of strength.

"A feather can't be added, and flies and insects can't fall" is a sign of turning energy, because a cultivator can control every inch of muscle explosion in his body, the feathers will bounce away, and the mosquitoes will be shocked to death.

After practicing a few half-step collapse fists, carefully experiencing the method of dark energy, the sun has risen very high, Chen Qi got dressed, and went down the mountain from the other side, he didn't go home, there is the Chen family's manor under the mountain, this is his private space, he has lived here for more than a year, and occasionally goes back home.

Back to the manor, bathing and changing clothes and bundling hair under the service of the maids, at this time, Xiao Xianger walked in with an account book, four years have passed, because of sufficient nutritional supplements, the yellow-haired girl of the year has grown up, except for the face is a little immature, can barely be called a girl.

"Xiang'er, what do you need to deal with today?"

"Little young master, the swamp on the east bank of Lishui has been reclaimed, and the steward has sent the income and expenditure account books last night, please take a look. Xiao Xiang'er replied competently. Chen Qi wants to make money and needs to have her own business, and there is a lack of people who can use it, so she taught her literacy and arithmetic, modern accounting management, etc., as her personal secretary, so far, she has done well.

"I remember, that swamp has been cultivated since last winter, why did it take so long?" took the ledger and looked at it himself, Chen Qi asked.

"Young master, this spring, there was a flood in Lishui, and it could not be reclaimed, so it was delayed for a long time. ”

"Oh," after a general look, the cost of clearing the wasteland was very large, but Chen Qi didn't care, this money would be earned back in a year or two. "Since the spring ploughing has been delayed, we must step up replanting in the autumn, and we must not delay the agricultural time, so let the stewards below supervise more. ”

Since Chen Qi was put on the name of meeting an immortal in a dream by that Xuansheng Daoist, although it brought him some trouble, it also gave him a good excuse to let go of his hands and feet, many things are much easier to do, and everything is pushed to the head of the dream immortal, and others can't question it.

Practicing martial arts was too expensive, Chen Qi wanted to make money, inspired by his grandfather Chen Shou to take in refugees for reclamation, and then investigated the farming technology of this world, and found that farming is a good way. The war in the Central Plains and the south of the Yangtze River is in great short supply, and the shipping and transportation are convenient, and the grain is not worried about the market, which can not only make money, but also live countless people.

Jiangnan and the Central Plains have many refugees fleeing from Lingnan, so there is no shortage of labor. Chen Qi bought all of them, organized them in the manor, each manor has a population of 200 households, all of them work together, they only need to hand over five layers, and the rest is theirs, the manor will distribute the grain according to the performance of ordinary work, and distribute it according to work, and everyone's labor enthusiasm is very high.

In order to improve productivity, Chen Qi purchased a large number of ploughing cattle, and also "invented" many advanced tools such as Quyuan plough and Lou Che, ordered people to establish a base of improved seeds, improve and optimize rice seeds, and most importantly, he also made soil compound fertilizers and soil pesticides.

Farmers in this world have long known how to use fermented manure to fertilize crops, but manure only contains a large amount of nitrogen, and elements such as nitrogen, phosphorus and potassium are essential for crop growth.

The main components of compound fertilizer are nitrogen, phosphorus and potassium, and the same is true for compound fertilizers made of soil. The source of nitrogen is mainly human and animal manure, which is fermented, dried, and then crushed into powder; the source of potassium is mainly plant ash, which can only be collected from house to house on the estate, but the quantity is not enough, so it can only be purchased by going out.

Most of the phosphorus in modern compound fertilizers comes from ores, but Chen Qi did not find phosphate rocks, so he can only replace them with small fish and rotten shrimp left over from fishermen's fishing, and of course, the leftover fish bones and scraped fish scales also contain a small amount of phosphorus. These are unwanted wastes, and fishermen are happy to exchange them for a little money.

On an isolated island in the middle of Lishui, Chen Qi secretly built a handicraft workshop, and all the people who worked were the sons of the Chen family, and the family was under control, mixing fecal powder, plant ash, and mashed small fish and shrimp.

Moreover, in order to keep it secret, Chen Qi added some clay and some harmless herbs to it, so that the black powder made in this way could not be seen by anyone, but there was a smell of traditional Chinese medicine, which should mislead many people. To the outside world, it is claimed to be the "fairy soil", which is the formula that Chen Qi was taught by the immortals in his dreams, and it is the spiritual soil that the heavenly immortals cultivate flowers and plants.

In order to prevent those smart people from guessing the secret of the soil compound fertilizer from the Chen family's raw material procurement, Chen Qi also made people purchase a lot of Chinese herbs, which were used by the orphans he took in to practice martial arts, as well as some messy things, such as fish vine leaves, mandala, tea seeds, castor seeds, etc.

Rotenone contains rotenone, which has a strong stomach poison and contact killing effect on pests. Grinding fish vines into powder, mixing them in water and spraying them can control many pests and diseases. Mandala, tea seeds, and castor beans are all used for the same purpose, ground into powder and added to water to make soil pesticides.

In this world, farmers have no other better way to pest and disease pests in farmland except to pray to God and worship Buddha and kill them by hand.

In fact, at the beginning, even the Chen family had little confidence in Chen Qi's compound fertilizer and soil pesticides, thinking that it was a child's foolishness, in this era of low productivity, for farmers, the field is the root of life, and the quality of a year's harvest is related to the life of the family, and those tenants of the Chen family are naturally unwilling to take a year's harvest to play with him.

In the end, there was really no way, Chen Qi could only beg his mother, and his mother spoke, and set aside ten acres of land to toss his baby son at will, as for the tenants of these ten acres of land, they don't have to pay rent this year, and the loss will be compensated by the Chen family.

A few months later, the 10 acres of land using soil compound fertilizer and soil pesticides obtained an unprecedented bumper harvest, and the yield of rice per mu reached 5 stone per mu, more than twice that of ordinary paddy fields, and the people of the Chen family were stunned.

Even Chen Shou, who has always been concerned about family affairs, was also shocked, he knew what this meant, so he issued a gag order, the Chen family was not allowed to spread the word, and allowed to expand the use of compound fertilizers and soil pesticides.

In fact, Chen Shou's first reaction was to report this matter to the Son of Heaven as auspicious, and he was likely to be reused again and return to the court. However, he was a little worried that this incident would have a bad impact on his grandson. The most important thing is that when today's son is unconscious, his relatives are in power, the eunuchs are interfering in politics, and the civil officials are busy with the party and fighting against differences, and no one cares about practical matters, Chen Shou is worried that his recital will not be able to reach the front of the emperor at all, so he can only give up.

In the second half of the year, as expected, the fields in charge of Chen Qi once again achieved a bumper harvest, which once again increased the confidence of the Chen family, and in the spring of the second year, all the fields of the Chen family, including the newly reclaimed manor, all used compound fertilizers and soil pesticides, and this bumper harvest could no longer be hidden.

The reputation of "fairy soil" spread throughout Jiujiang City, and gradually expanded to the entire Lingnan County, and at the same time spread Chen Qi's reputation, what was born full of red light, the mother dreamed that the golden carp was conceived and pregnant, born intelligent, both civil and military, and met the immortal education in the dream, made the "fairy soil" and so on, and suddenly became a household name and became someone else's child.

Several bumper harvests, the Chen family did not lack food, only the added value of selling grain was too low, so Chen Qi "invented" distilled liquor, but unexpectedly, the hot distilled liquor was not as popular as imagined, although some people tried it curiously, but they gave up, saying that the wine was too strong to drink, and they still liked low-alcohol rice wine.

In the end, Chen Qi thought of a way to contact the main family in Luoyang and ask them to transfer the soju to the northern barbarians, where the world was bitterly cold, and the hot soju was really popular and in short supply.
