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

Reiner was wearing very ordinary coarse cloth clothes and boots, which were suitable for working in the fields. Claire was standing behind Reiner holding a stack of things.

There were three students present. Needless to say, Dana, Fina also stayed at the school after taking the magic test. When the new semester arrives, she will officially become an assistant teacher at Crescent College.

The third person is Xia Luo. She originally planned to go home during the summer vacation, but later decided to stay in school. While she continued to complete the drawing of the mage card, she could also use the equipment in the school to continue experiments.

Reiner did not call other teachers. Originally, teacher Susan Michelle, who taught the necromancy department, should be able to help. However, she went back to her hometown to visit relatives and was not in school at the moment. Reiner did not disturb the other teachers.

"I didn't expect these peas to have grown like this. It seems that the greenhouse effect is quite good."

Reiner looked at several fields. The seeds he sowed yesterday had now sprouted green shoots. According to the user manual, Reiner adjusted the environment here to the most suitable type for the growth of peas, which could increase the growth rate by about fifteen times. s efficiency.

The growth cycle of ordinary peas is about sixty to ninety days, but in this greenhouse, it only takes one week to harvest and mature.

If the growth cycle is carefully planned, Lena can at least get four to five mature peas in these twenty days.

"But why peas?"

Dana asked. To be honest, she didn't like eating peas, and she had no interest in growing peas. The reason why she came here was because of Reiner's invitation.

Previously, Reiner had explained to these students about the blood mage and Emiya. For them, Emiya's situation was unimaginable, but this did not prevent them from working hard for this. Take action with classmates.

"The first thing is that peas have a lot of distinct characteristics."

Reiner said, spreading out the information on Peas on the table nearby.

"Tall stems and short stems, white flowers and red flowers, whether the pea grains are smooth or wrinkled, these are very obvious and easy to distinguish characteristics, and due to the planting needs of different areas, pea seeds with these characteristics have been made After screening, everything is ready-made.”

The information depicts the various forms of pea plants,

The difference is obvious. For these students, they only knew that peas are a vegetable, but they did not understand that there are so many differences.

"The second point is that pea itself is a special plant. During the flowering period, other plants mostly rely on animals such as bees and butterflies, or the wind in nature for pollination. It is difficult to control the source of their pollen, but peas are different. It’s a self-pollinating plant.”

To put it simply, self-pollination is the pollination of the pistils and stamens of the same pea plant. The pea plant has completed the pollination process before flowering, and will not be affected by other pollen afterwards. Therefore, each pea plant is guaranteed to be the same plant. Combine the remaining peas.

"Hey, isn't this similar to the pure-blood faction?"

After listening to Reiner's explanation, Xia Luo said as if she had a sudden realization.

In order to ensure the purity of their bloodline, the pure-blood sect also strictly engages in intermarriage, which is a bit similar to Peas.

"Although the principles may be somewhat different, this idea is quite novel."

Reiner praised Charlotte, which made the other two girls feel a little inexplicably disappointed. He did not notice this and then concluded.

"These characteristics of pea allow us to control the source of its offspring and facilitate experiments."

Through various means, peas can be hybridized and their appearance characteristics can be observed to determine the action process of the blood factor that Reiner guessed.

Reiner assigned each student two fields and asked them to observe the growth process of peas and record specific characteristics.

This was the first time for these girls to work in the fields. Although they did not really wield a hoe, they also learned many things that they had not understood or misunderstood in the past.

For example, Dana, before this, she always thought that peas grew one by one among the leaves. It was not until today that she knew that there was such a thing as pods.

After an afternoon of observation, several people left the greenhouse. Only some of the peas cultivated in the first phase required artificial pollination, so they did not need to spend too much energy. They only needed to come over regularly to check the growth status.

During the past few days, Reiner was not idle. He first looked through some information about pure-blood mages to see if others had noticed similar phenomena, but found nothing.

Pure-blood mages are originally a very secretive and exclusive lineage. They also have a lot of confidence in their own inheritance. Naturally, it is impossible for outsiders to study it. And their own development of bloodline is a bit more special. Even if a similar situation occurs, Like this time, it will be treated as an affair or other reasons.

Then, Reiner looked at the necromancy system's research on magical creatures. You must know that whether it is agriculture or breeding, the requirements for pure breeds are very high. The pea seeds this time are a kind of unique The product of conscious experience, he tried to find out the experiences of mages in cultivating magical creatures with specified traits.

But soon, Reiner discovered that because there were too few applications of modern magic theory in the necromancy system, mages used the same method of continuous cross-breeding and screening to cultivate these species, similar to cultivating pea seeds, and there was almost no research on the theory.

Finally, Reiner carefully reviewed the El Aure family's genealogy for the past three hundred years, subdivided and counted their physical features, and made a table for emergencies.

Four days later, the first batch of peas officially matured, and Reiner and the students came to the greenhouse again to check the growth status.

"Field No. 1, 100% tall-stem plants, Field No. 2, 100% short-stem plants..."

Claire was making statistics based on their observations, but at this time, Dana felt confused.

"Hey, weird, are fields No. 10 and No. 11 planted with tall peas?"

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

"No, both fields were hybridized. In field No. 10, the stamens of tall peas were used to pollinate the pistils of short peas. In field No. 11, the reverse was done, with the stamens of short peas pollinating. To the pistils of tall peas.”

Reiner explained aloud that the experimental phenomenon in front of him was the same as what he remembered, which made him smile lightly.
