When there is a person who has something to do, time passes the fastest, when Zhao Yao can successfully brew Yao wine, almost every day in the Lingtian non-stop brewing, an average of about three or four hours can successfully brew about seven or eight catties of Yao wine, the rest of the wine lees except for a small part left to mix into the new material, the rest of the rest are buried in the Lingtian.

In this way, in addition to cooking grain, brewing wine, and practicing boxing every day in the Lingtian space, Zhao Yao is studying how to improve the grade of food.

According to the introduction of the spirit plant decision, Zhao Yao knew that the plants in the world are divided into four orders and twelve products, which are the three grades of the mortal rank, the three grades of the spirit level, the three grades of the fairy world, and the three grades of the god level.

This is like the sorghum planted in Zhao Yao's spiritual field now, the sorghum that circulated in the original reality is just the most ordinary plant, although it is different from other weeds in terms of efficacy, but in essence, it is no different from the weeds in those fields.

However, since the seeds of these sorghum have been nourished by Zhao Yaoling's planting, the sorghum that grows again is not an inferior quality, but can be regarded as a medium quality, so his yield is so high, basically two or three times that of ordinary quality.

But the seeds of a product, Zhao Yao is still a little dissatisfied, because in this world, but can grow a four-grade plant, although it is extremely rare, and the required conditions are too harsh, but it does exist, such as 10,000 years of blood ginseng, 10,000 years of iceberg snow lotus, 10,000 years of He Shou Wu, etc., etc., many species that have basically not existed in the world now, have existed before, it is really the seeds of these things themselves can reach a product, after years of baptism, the quality has gradually improved, It has reached the level of the four grades, but once they reach the four grades, it is equivalent to stepping into the category of the spirit level, deriving a sense of self-protection, and it is basically impossible to catch them, unless they are the peak powerhouses in the world, it is difficult to catch them.

As long as it exists, then it is impossible not to fight for it, not to mention Zhao Yao, who still has a spirit plant that can help plants improve their quality, of course, there is another reason why Zhao Yao is determined to improve the quality of food, that is, these days he found that although the wine he brewed with these low-grade grains is delicious and can satisfy hunger, it doesn't seem to have much effect on the increase of his own qi and blood. Then these low-grade Yaojiu are his help is huge, but now Zhao Yao is already equivalent to the peak of dark energy and even the master of the transformation realm, and the strength of his body is much stronger than that of ordinary people, and then using these things to replenish qi and blood is obviously not enough.

Therefore, after Zhao Yao grew three forks in the sorghum, he specially selected the largest and fullest thirty catties of grain from tens of thousands of catties of grain as seeds, and spread them on the Lingtian, but these seeds were not buried in the Lingtian, but a layer of paper was separated from the Lingtian.

Zhao Yao was barefoot, both feet were all buried in the Lingtian, after taking a deep breath and adjusting his breathing, the spiritual sense mobilized the internal force in the body that had become somewhat powerful after so much weather and blood nourishment to reach his hands, and the handprints kept changing, and when he finally froze in a certain posture, a rain cloud appeared in the air of the Lingtian.

The raindrops falling from the air are particularly dense because they only act on the dozens of catties of tiled seeds, basically forming a rain line between the clouds and the seeds, each rain line corresponds to a seed, and those seeds that are originally relatively full begin to become more full after being exposed to the moisture of the spiritual rain.

I saw that these seeds were still some irregular ovals at the beginning, but with the moisture of the spiritual rain, they began to change in the direction of a circle, and when these seeds turned into spheres with a diameter of two centimeters, their volume stopped growing, and this time the spiritual plant was also at this moment, the end.

Holding those seeds that have changed greatly, Zhao Yao couldn't see how different it was from other seeds when he looked left and right, but it was just a little bigger and a little rounder, as for the grade, it was still the category of a first grade, and it had not reached the level of a second grade at all, according to Zhao Yao's thoughts, these seeds that had been nourished by a second-layer spiritual plant should soon be able to reach the quality of the second grade, but the reality is not so.

In fact, Zhao Yao is also a little in a hurry, the grade of plants is generally destined by God, this is like the origin of people, some people are born with a net worth of tens of millions, but some people are born with a lot of debts, there is no way to compare people with people, only through the continuous efforts of the day after tomorrow, it is possible for you to reach that level.

This principle is more obvious when applied to plants, the seeds grown by low-grade plants are impossible to become high-quality seeds, which is why people always want to mutate the seed genes, or hybridize, trying to use this method to achieve the purpose of improving their quality, but these attempts are successful after many generations of efforts, not a one-time problem.

But Zhao Yao is a farmer who graduated from junior high school after all, he doesn't know so much, he just knows that since the grain can be highly productive through hybridization, then I will definitely be able to do it with Lingzhi Du, after all, Lingzhi Duel is introduced like this.

So Zhao Yao stumbled with the seeds of these grains, and the two spiritual plant duels every day were all used on the seeds, but these seeds were nourished by the spiritual plant duel, but they only became more mellow and full every day, but the grade did not improve in any way.

Zhao Yao, who had cast dozens of spirit plant duels on these seeds, was dumbfounded after seeing that the raindrops summoned by the spirit plant duel could not enter the seeds, he didn't understand, it was clearly explained in the spirit plant duel that the spirit plant duel could improve the grade of the plant, but Zhao Yao, who was actually operating, couldn't see the signs of seed promotion.

Zhao Yao, who couldn't figure it out, had no choice but to think that maybe these seeds were not good, so he buried all these seeds in the spiritual field, and selected more than 30 catties of seeds from the newly grown sorghum, and experimented again.

Planting crops in the spiritual field, without the help of the Spirit Plant, their growth cycle is one-third of the reality, that is, the crops that take three months to mature outside, it really takes a month here, but if you add the Spirit Plant, it is one-tenth.

Just when Zhao Yao was casting the Spirit Plant Determination on those newly selected seeds, Zhao Yao didn't notice that the growth of the seeds he had planted before, which could no longer accept the nourishment of the Spirit Plant Decision, was much fuller than those ordinary seeds, almost half the speed of those seeds, but although they grew slowly, they were more than twice as strong as those seeds.

"Oh, what's going on, why is it still not working, why don't these seeds absorb the spiritual rain formed by the Spirit Plant Determination after receiving the nourishment of the Spiritual Plant Determination twenty times? Why is that? Is it saturated? Isn't it, there are times when the seeds are saturated? Kindness? This is? ”

It is not surprising that after experimenting four times again, Zhao Yao found that the selected waves of seeds were the same as the first time, and they all stopped absorbing the spiritual rain after receiving twenty times of spiritual planting to become round and full, this discovery made Zhao Yao a little unacceptable, just when Zhao Yao was holding his newly picked seeds in his hand and meditating, his eyes suddenly looked in the direction of Lingtian, and his eyes were full of disbelief.

It turned out that because his attention was focused on how to improve the seed level these days, he didn't notice the growth of the seeds that were planted back into the ground by himself and were full of spiritual rain, and a month and a half had passed in the spiritual field unconsciously, but when he looked at the spiritual field out of the corner of his eye just now, he found that there was no ordinary sorghum in the current spiritual field, but instead there were sorghum as thick as sugar cane and ears as big as bananas.

"Oh my God, this sorghum already has a top quality, and this is what my seeds that have performed the Spirit Plant Determination grow?"

Zhao Yao walked closer, while stroking the sorghum ears that were the size of bananas, and at the same time let out a burst of emotion in his mouth, only to see that the new sorghum has completely changed its appearance, they are not single big and stout, and the fruits are no longer oval like ordinary sorghum, but are arranged one by one on the ears like glass beads, and smell them with your nose, and you can smell a faint fragrance unique to grain.

"Well, no, I'll have to test this thing again and see if it works."

Zhao Yao, who was surprised for a while, immediately returned to improving the quality again, and after holding a sack containing twenty or thirty catties of grain seeds, he spread them on the ground again, and the handprints of his hands flew up, and the spirit plant was displayed again.

Another experiment, so that Zhao Yao's heart is full of joy, not for anything else, just for him to see the hope of the seed to improve the quality, at the moment when the spirit plant decision was cast, the spirit rain began to be continuously absorbed by the seeds, with the continuous moisturization of the spirit rain, the color of the seeds began to change significantly, just a spirit plant decision, it turned the color of the seeds from yellow dark red to golden yellow, and the original layer of light red on the seeds has disappeared.

In fact, this time, Zhao Yao found a way to improve the quality of plants by mistake, as we all know, the quality of plants is not a touch, it takes several generations of continuous evolution and formation, just like the evolution of animals, if the environment changes dramatically, then he will die, but his next generation or the next generation will make changes, this is natural selection, the evolution of species, the same is true for plants, Zhao Yao just took the seeds of a generation of sorghum and worked hard, If this generation of seeds is not allowed to take root and sprout and grow into the next generation, then it will reach the limit that their generation can reach, but if they are allowed to multiply the next generation when they reach the limit, then the next generation is the limit as soon as it is born, so at this time, if you cast a spiritual plant decision on the next generation, it will prompt the next generation to reach the limit, and so on several times, the quality of the plant will naturally improve.

Zhao Yao, who figured out the reason, began to plant, harvest, nourish, and plant this cycle of continuous planting, harvesting, nourishment, and planting, when these seeds were recycled ten times, the golden sorghum seeds finally appeared in front of Zhao Yao's eyes, smelling the faint fragrance emanating from the seeds, Zhao Yao really wanted to look up to the sky and sigh, "Sorghum, you have finally grown to the second grade." ”
