Early the next morning, in the greenhouse plantation on the western outskirts of the school, several students were yawning and standing a little lazily.

Reiner was dressed in a very ordinary coarse cloth suit and boots, suitable for working in the fields, and Claire stood behind Reiner with a stack of papers.

There were three students present, and Dana naturally needless to say, Fina also stayed at the school after the magic test, and when the new semester arrives, she will officially become an assistant teacher at Crescent Academy.

The third is Xia Luo, who was originally going home for the summer vacation, but later decided to stay in school and continue to complete the mage card drawing while also using the equipment in the school to continue experimenting.

Reiner didn't call the other teachers, originally, Susan who taught the necromancy. Ms. Michelle should have been able to help a little, but she was back in her hometown to visit relatives and was not at the school at the moment, so Reiner didn't bother the other teachers.

"I didn't expect these peas to grow like this, and it seems that the effect of this greenhouse is quite good."

Reiner looked at a few fields, the seeds he had sown yesterday had now sprouted green sprouts, and Reiner had adjusted the environment to the most suitable type for peas to grow according to the manual, which could increase the efficiency by about fifteen times.

The growth cycle of ordinary peas is about 60 to 90 days, and it only takes a week to harvest and ripen in this greenhouse.

With careful planning of the growth cycle, Reiner will be able to obtain at least four to five sow of ripe peas in these twenty days.

"But why did you choose peas?"

Dana asked, to be honest, she didn't like peas, and she wasn't interested in growing peas, and she came here because of Reiner's invitation.

Reiner had already explained to the students about the Bloodline Mage and Arymia, and for them, Arymia was in an unimaginable situation, but that didn't stop them from acting for her classmates.

"First of all, peas have a lot of distinct characteristics."

Reiner said, spreading out information on peas on a nearby table.

"Tall and short stems, white and safflower, smooth or wrinkled pea kernels, these are very obvious and easily distinguishable characteristics, and the pea seeds with these characteristics have been selected and readily available due to the previous needs for cultivation in different regions."

The various forms of pea plants are depicted in the materials, and the differences are clear, and for these students, they used to know that peas are only a vegetable, but they don't understand that there are so many differences.

"The second point is that the pea itself is a special plant, and most of the other plants rely on bees and butterflies during the flowering period, or the wind in nature to pollinate, and it is difficult to control the source of their pollen, but pea is different, pea is a self-pollinating plant."

Self-pollination is simply the pollination of the pistils and stamens on the same pea, the peas have completed the pollination process before flowering, and will not be affected by other pollen after that, so each pea can ensure that the previous pea is combined with the previous pea.

"Hey, isn't this a bit like a pureblood?"

After listening to Reiner's explanation, Xia Luo said with some sudden realization.

In order to ensure the purity of the bloodline, the pure-blood faction also strictly intermarried, which is really similar to peas.

"The principle may be a little different, but it's a novel idea."

Reiner praised Charlotte to the other two girls a little inexplicably disappointed, and he didn't notice this, and then concluded.

"These properties of peas allow us to control the origin of their offspring, which is convenient for experimentation."

Through various means, peas can be crossed, and their physical characteristics can be observed, so as to determine the process of action of the blood factor that Reiner guessed.

Reiner assigned each student two plots of land to observe the peas and record specific characteristics.

This was the first time the girls had worked in the fields, and although they didn't really swing a hoe, they learned a lot of things that had not been clear or misunderstood before.

For example, Dana, before that, she had always thought that peas grew one by one in the middle of the leaves, and she didn't know that there was such a thing as a pod until today.

After a morning of observation, a few people left the greenhouse, and only some of the peas cultivated in the first phase needed to be pollinated by hand, so it didn't take much effort, just come back regularly to check the growth.

During these few days, Reiner was not idle, he first looked through some information about pureblood mages, looking for others to see if they had noticed a similar phenomenon, but found nothing.

Pure-blood mages are already very secretive and xenophobic, they also have a lot of confidence in their own inheritance, naturally it is impossible for outsiders to study, and their own development of the bloodline is a little more special, even if there is a similar situation, it will be like this time, as it is, as fornication or other reasons.

Then, Reiner looked at the necromancer's research on magical creatures, you know, whether it is agriculture or breeding, the requirements for purebred are very high, like this pea seed, which is a product of unconscious experience, and he tries to find the experience of mages about cultivating magical creatures with specific traits.

However, Reiner soon discovered that because there was so little application of modern magical theories in the necromantic system, the mages used the same method of continuous cross-breeding and selection as the cultivation of pea seeds, and there was little theoretical research on cultivating these species.

Finally, Reiner carefully checked the genealogy of the Elbiore family for nearly three hundred years, subdivided and counted the physical characteristics in it, and made a table in case of emergency.

Four days later, the first peas were ripe, and Reiner and the students returned to the greenhouse to check the growth.

"Field No. 1, 100 percent tall stems, Field No. 2, 100 percent short stems, ......"

Claire counted their observations, but Dana was puzzled.

"Hey, it's strange, are the tenths and elevenths all grown with tall peas?"

She looked at the tall pea seedlings in front of her and asked Claire.

"No, both fields were hybridized, field 10 pollinated the pistils of the dwarf peas with the stamens of the tall peas, and field 11 was the opposite, with the stamens of the dwarf peas pollinated the pistils of the tall peas."

Reiner explained aloud, the experimental phenomenon in front of him was the same as he remembered, and he smiled faintly.
