The most typical and oldest hybrid breeding method is the three-line hybridization.

The so-called three lines are both sterile lines, maintenance lines and recovery lines.

Among them, the sterile line is used as the female parent, the stamens are shriveled and degenerated, and they cannot fertilize and produce seeds, but they can produce different seeds by finding two objects, and the daughter born is like the female parent, that is, the maintenance line, and the son born has a sound pollination mechanism, that is, the recovery line.

These three lines, the sterile line and the maintainer line, produce offspring that are still sterile lines, to achieve the purpose of breeding sterile lines, and the infertility lines and restorer lines pollinate, and the offspring produced are hybrid products that can be planted in large quantities.

But it is obviously impossible for the spiritual rice planted by Qin Yuan to have an infertile female parent that cannot be fertilized at the beginning, in this way, for Qin Yuan, there is only one way, that is, artificial emasculation, fortunately, Qin Yuan's spiritual field is not large, and the spiritual rice planted cannot be a lot, so the work of emasculation is not very troublesome.

And these were not Qin Yuan's primary tasks, his primary task was to determine the spiritual rice seeds to be cultivated.

There are more than 300 Lingmi seeds, not every kind of hybridization will be successful, even after the hybridization is successful, the cultivated Lingmi is not necessarily within Qin Yuan's acceptance range, for example, the seeds formed by the hybridization of two yellow-grade seeds are still yellow-grade seeds, which is obviously unacceptable, so many yellow-grade seeds, there is not much more than you, and there are many less than you.

The planting cycle of Lingmi is different according to different grades. Generally speaking, the Lingmi cycle of the lower grade of the yellow level will not exceed one month, if the quality of the Lingtian is higher, this time will be shortened, just like Qin Yuan's Yanyu Peak is a tributary of the spiritual vein provided for cultivation in the Jindan period, and the Lingtian will naturally improve by a grade.

And in this way, these seeds in Qin Yuan's hands only took a maximum of twenty days from planting to maturity. It takes even less time to produce pollinated stamens, as little as 10 days.

Officially started planting, Qin Yuan knew that farming was not easy, took out the refined soil-breaking hoe containing the ground-breaking prohibition, and worked hard to turn the ground on the long-abandoned spiritual field in the back garden, every time he turned the ground and loosened the soil, Qin Yuan needed to consume a lot of true qi to complete, and the earth-breaking hoe could save Qin Yuan five points of true qi consumption, which was better than nothing.

In three days, Qin Yuan completely turned into a peasant, his face turned to the ground and his back to the sky, singing the ballad of sweat dripping into the soil, and buried himself in hard work.

Sow the seeds that have been selected a long time ago, spread the wood-raising formation based on the plate base of the forbidden wood-raising technique, and insert cloud and rain flags on the edge of the spiritual field, and the sowing work is completed.

Every day, Qin Yuan would give a spiritual rain with cloud and rain banners to provide enough spiritual water to the seeds.

The seeds are growing day by day at a speed visible to the naked eye, and every day there will be one or two spirit seedlings that are borers, and they will be quickly cleaned up by Qin Yuan, and the same spirit rice seeds will be replanted, he doesn't have time to learn the magic spell of removing moths, only the probability of no moths in exchange for quantity, which is also the reason why he buys ten of each seed, if he is unlucky, ten of the same seeds will appear borers, and he has to buy more.

For the first time to go to the ground, all the seeds Qin Yuan chose were fire attribute seeds, and only one or two were sun attribute and yang attribute seeds.

Ten days later, Qin Yuan personally removed half of the fire attribute seed stamens, and kept the other half for breeding. Pollinate with the seeds of the day and yang attributes. After another ten days, the pollinator seedlings did not bear ears, and the result was obvious, and the pollination failed.

In the sea of Qin Yuan's knowledge, on top of a spiritual root leaf, all the Lingmi hybridization sequences were densely listed, and a small part of them were marked with the word failure at the back.

Three months later, four or five batches of spiritual rice seeds had been replaced in the spiritual field in Qin Yuan's back garden, and without exception, all of them failed to pollinate.

At this time, the brute force Houhai broke through one after another, and Qin Yuan took a closer look, and saw that the two of them had refined the five extremes and five apertures, and their cultivation had been consolidated.

Since the two of them are out of the customs, Qin Yuan can naturally liberate some of the labor and teach brute force how to de-male and pollinate the spirit rice; this is effortless in brute mechanics, after all, Qin Yuan has cultivated brute force as an experimental assistant since he was a child, and Hou Hai is of course also a helper behind him.

Detached from the permutations and combinations of Lingmi hybridization, Qin Yuan began to put the transformation of subconscious intelligence coding on the agenda, if this can be successful, Qin Yuan believes that the supernatural power composed of three elements based on the wisdom brain is definitely one step closer to becoming a small supernatural power.

However, before that, Qin Yuan first needed to digest the results of the Spirit Root Manifestation Ceremony.

A month later, Qin Yuan comprehended the Spirit Root Manifestation Ritual Formation recorded on the leaves of the Spirit Root to the limit of what he could comprehend now, absorbing the merits of it, Qin Yuan increased the efficiency of the computing core by more than one percent, the composition between the runes and the runes was more reasonable, and the improvement of the database core was more significant, the efficiency of scanning the sea was doubled, and the way of storing information was more reasonable, so that the Spirit Root saved one percent of the storage space. Because runes are patterns with power, compression mode does not work on runes, and if you do so, you will only lose the true meaning of the runes themselves. Therefore, the improvement of storage efficiency is a very rare thing.

And during this period of time, the hybridization of Lingmi finally had a phased breakthrough, on Qin Yuan's document leaf called Lingmi hybridization, a sequence of information is no longer marked as a failure, but a successful pollination, and the offspring seeds are yellow-grade medium-grade.

The medium-grade yellow-grade seeds are still in the category of ordinary seeds, and they are not within the scope of mass production that Qin Yuan is considering, so it is not worth Qin Yuan to invest more resources in this.

After finishing all this, Qin Yuan entered the secret room retreat, this time, he wanted to put aside other trivial matters and wholeheartedly study the matter of subliminal intelligence transformation runes, which was a very crucial step for Qin Yuan's rune brain research.

Just a month after Qin Yuan entered the retreat.

Jianzhu Peak, this is the cloud island that Mu Chuan was assigned to after entering the sect, the word Jianzhu, is also named after his spiritual root rune map, because it is the relationship between the two spiritual roots, he was also assigned to a good cloud island. In fact, as long as the disciples who join the peak vein in advance, they will have some limited independent choices, which can be regarded as the invisible welfare and preferential treatment of each vein.

After the end of the introductory oath, the three peaks of the wood vein, for the new disciples of the sect, will have an inspection period of half a year to a year, after the end of the investigation, the peak master of the three peaks, the elders will consider whether to accept them as introductory disciples according to the performance of the disciples in the door, and the disciples who fail to enter the Dharma Eye can only be ordinary disciples of the three peaks, and they can only rely on the Five Elements Hall for everything, solve their own cultivation questions, and so on.

Of course, the three major pulse peaks will not give this matter to death, and the remaining ordinary disciples will enter the second five-year disciple investigation, and those who have not yet been selected as introductory disciples will have a last ten-year investigation period, after this time, if they have not been able to be accepted as a disciple by the top level of the three peaks, then this person can only be an ordinary disciple in the Haoyang Sect for life.

And those who are accepted as beginner disciples are not at ease, and during the three inspection periods, the master can also expel the apprentice from the door wall at any time, and in serious cases, he will even be expelled from the Haoyang Sect.

The Wood Vein, among the five veins, is the strictest in accepting introductory disciples, and it is also the one that follows the tradition the most, so even the disciples of the Pure Wood Spirit Root are no exception in this regard.

It's just that Mu Mai has not had a pure spirit root disciple join for a hundred years, and this time Qin Yuan's entry, his master Ku Lao also withstood a lot of pressure from within the Three Peaks, but this only allowed Qin Yuan to save the first disciple inspection.

Strictly speaking, Qin Yuan was only in the disciple inspection period, and this fifteen-year inspection period was not too short.

Naturally, for Qin Yuan, whether there was such an inspection period was not within his consideration at all. However, Qin Yuan is also famous among the wood veins, but Qin Yuan has always been a divine dragon who sees the head but does not see the tail, and the disciples in the wood veins only hear his voice but do not see his person.

Moreover, since Qin Yuan took out the Heavenly Dao Ash and exchanged it for his first pot of gold, the voice in the wood veins that was quite complaining about Qin Yuan was also much quieter, and because of this, it put a veil of mystery on Yanyu Peak.

Let's go back to Muchuan, Muchuan's family background is much stronger than Qin Yuan's three, one of the three major sects under the Haoyang Sect, one of the families in the Tianyi Sect's affiliated empire Jin Phosphorus, is the place where Muchuan was born.

In Muchuan's generation, the two elder brothers above Muchuan failed to manifest their spiritual roots when they were in Haoyang Sect, which was a big blow to Makikawa's family.

As a result, the Mu family's power in the Haoyang Sect has reached the lowest level in the past, although the family is struggling to support, but after all, it is only a small sect in the empire, and the influence on the family in the empire is minimal.

It wasn't until the successful manifestation of Makikawa's spiritual root that Makikawa's family saw a glimmer of hope.

But as the saying goes, where there are people, there are rivers and lakes.

Since it is an imperial family, it is impossible for a family without hostile forces to exist within the empire. The Flint family is the long-standing enemy of the Makikawa family.

This generation of the Flint Family can be described as thriving, and coincidentally, just when Mu Chuan was glad that he had succeeded in manifesting the Spirit Root, his family's sworn enemy, the Flint Shi Yu of the Flint Family, also joined the Divine Fire Peak of the Fire Vein in advance with the qualification of the Twin Spirit Root.

Then, the trouble came.

That flint Shi Yu didn't know what method he used to catch up with a big man in the Divine Fire Peak.

At the end of Muchuan's three-month retreat and consolidation, he received a letter from his family, and the family power entered a comprehensive contraction defense under the suppression of the Flint family, and most of the family's property was also pocketed by the Flint family.

Mu Chuan's family spent a lot of money to find out that there were internal forces of the Haoyang Sect involved, and the letter asked Mu Chuan to inquire about the ins and outs as soon as possible.

Before the joy of manifesting the spiritual root had passed, Makikawa's heart had already sunk to the bottom.

When he was a child, Makikawa grew up in the pampering of his father, mother and two elder brothers, until the failure of the two elder brothers to manifest the spiritual root, he gradually felt the heavy pressure from the outside world, although his parents and brothers did not exert any pressure on him, but it was at that time that Makikawa suddenly felt that he had grown up, and he knew that he had to stand up and do something for his family and his relatives.

After that, under his stubborn insistence, Mu Chuan was sent to the Dongyang Courtyard in the lower courtyard of the Haoyang Sect to cultivate immortals and practice qi.
