Building infrastructure in the wizard world

Chapter 84 This is just the basics
Mu Guan paced back and forth in the classroom, but his eyes were fixed on the screen, not wanting or daring to miss any word on it.

"The classification of plants is complex and diverse. Here are a few classification methods."

"As follows: Classified according to the mode of reproduction, spore plants are divided into algae, bryophytes, and ferns. Seed plants are further divided into gymnosperms and angiosperms.

Divided by low and high: higher plants are divided into bryophytes, ferns, and seed plants.The lower class is divided into algae and fungi.

Classified according to the shape of the plant stem: trees, shrubs, subshrubs, herbs, vines.

Classified according to the ecological habits of plants: terrestrial plants, aquatic plants, epiphytes, parasitic plants, saprophytes.

Plants are classified according to their life cycle: annuals, biennials, and perennials. "

While the video is preaching, it also plays the corresponding plants for examples.

Mu Guan looked at the colorful and colorful plant world on the screen, and he fell into that colorful world.

"Is it true? Is it true?"

Shi Hao didn't answer the wooden crown.

The video continues.

"Take the example of trees again.

Classified by tree growth type: arbor, tall trees, usually 6 meters to tens of meters, with obvious tall trunks.Shrubs, the tree body is short, that is, usually below 6 meters, and the trunk is short at the bottom.Vines, woody plants that can grow upward by winding or clinging to other things, such as creepers.Creeping species, stems, branches, etc. all grow on the ground, such as pagoda cypress.

Classified according to the adaptability to environmental factors: according to thermal factors, tropical tree species, subtropical tree species, temperate zone tree species and frigid sub-frigid zone tree species.According to the water factor, it can be divided into drought-tolerant tree species and humidity-resistant tree species.According to the light factor, positive trees, neutral trees, and negative trees can be graded in each category.According to air factors, there are four types of wind-resistant tree species, smoke-resistant and toxic gas-resistant tree species, dust-resistant tree species and health care tree species.According to soil factors, acid-loving tree species, alkali-resistant tree species, barren-tolerant and coastal tree species. "

After listening to the voice, Mu Guan's expression was dull, and he kept muttering to himself.

"Is it true? Is it true?"

The only answer to him was the voice of the video.

"Why do we classify plants?"

"Plant classification is mainly to study the origin, kinship, and evolutionary development of different groups of the entire plant kingdom. It classifies the complex plant kingdom until it is identified, and arranges it systematically, so that people can understand and use plants."

Mu Guan saw that the video went dark, and the light in his eyes also dimmed.

At this moment, Shi Hao pushed the door open and came in, against the light.

In the eyes of Mu Guan, Shi Hao is like a god descending from the sky. He crawled to Shi Hao's side, grabbed Shi Hao's trousers and asked: "Is it true? Is it true? What is said above is true Is it?"

Shi Hao didn't answer Muguan's question directly, but moved his gaze out of the window, and landed on the sycamore tree in the west.

The wooden crown followed Shi Hao's gaze, and he finally found these trees that didn't exist before.

"Then, what is that? What kind of tree?" Wooden Crown eagerly asked.

"Sycamore tree, a plant of the sycamore family of the sycamore family, is a deciduous tree.

Its twigs and petioles are more or less yellow-brown pubescent, and the white medulla in the branches is separated by pale yellow thin slices.Leaf blade broadly ovate, ovate, triangular-ovate or ovate-elliptic, apex acuminate, base truncate or broadly cuneate, rarely subcordate, margin entire or with wavy teeth, sparsely pubescent or nearly pubescent on both surfaces hairless. "

"If you are interested, you can study it by yourself." Shi Hao said flatly, for him, this is indeed a commonplace and trivial matter without fluctuation.

"You, are you a god?" Mu Guan muttered to himself.

Shi Hao shook his head, directly denying the admiration and belief projected by the wooden crown.

"Only people with a weak heart will try to become a god." Shi Hao said: "I am not a god, and I don't want to become a god."

After finishing speaking, Shi Hao moved to Tu Yuan's room.

Tu Yuan looked tense and fearful.

From the beginning of the video, he told Tu Yuan: "Soil can be divided into three categories: sandy soil, clay soil, and loam soil."

And, what is red soil listed in detail?What is brown soil, cinnamon soil, and black soil.

He told Tuyuan how to cultivate chestnut soil, desert soil, fluvo-aquic soil, irrigated silt soil, and paddy soil.

Taught Tuyuan how to distinguish wet soil from swampy soil.

And tell Tuyuan how to prevent land salinization.How to change and utilize lithological soil and alpine soil, etc.

This information is absolutely shocking to Tu Yuan, who grew up in the soil and dealt with the soil since childhood, no less than the shock of earthlings seeing aliens.

"This is a secret, this cannot be seen by others!" Seeing Shi Hao enter the classroom, Tu Yuan hurriedly ran to Shi Hao's side, and said nervously: "Put it away quickly. This cannot be seen by outsiders, and this cannot be spread."

Tu Yuan knew the value of this knowledge, just how the paddy soil was cultivated was worth a city.

Not to mention that there is still so much knowledge about the land, knowledge like the stars and the sea, how can this be spread?
Tu Yuan wished to take this knowledge as a sacred object, enshrine it back to the village, and keep it forever. This knowledge deserves to be placed carefully and preserved properly.

Can.Shi Hao spoke casually.

"Don't be nervous, it's just some basic knowledge of bad streets." Shi Hao said nonchalantly.

he?what did he say?
These god-like rules, such knowledge shining like stars in the sky, are actually in Shi Hao's mouth, just some bad knowledge?
At this moment, Tu Yuan's faith collapsed, and he couldn't recover for a long time.

Shi Hao walked out of the classroom, and gently closed the door.

Some emotions can only be left to Tu Yuan and the others to resolve themselves.

When Shi Hao came to Shuiyan's classroom, he saw Shuiyan staring at the screen like a scumbag reading a book from heaven.

As soon as Shuiyan saw Shi Hao coming in, he immediately ran over like a katti dog seeing its owner.

"Director, the groundwater mentioned above is the water we drink!"

"Where is the ultrapure water?"

"Where is the crystal water? You tell me, I will definitely find them back."

"The video also said that there is heavy water and super-heavy water, and that super-heavy water is only one billionth in nature. Is this true? I'm going to get it back for you."

Shui Yan's face was full of excitement, uncontrollable excitement, he kept asking Shi Hao questions, and kept wanting Shi Hao to answer.

"Eh..." Shi Hao waved his hand and said, "I don't know."

"How come you don't know?" Shui Yan blurted out, in his eyes, Shi Hao is omniscient and omnipotent, invincible in the world, and a god descending from the world.

Now Shi Hao actually said that he didn't know?
Shuiyan immediately looked like I understood, and said quickly: "Director, I know you know. You just want to test me, you want to test our water village. Don't worry, our loyalty is worthy of your trust, and we will always be Your supporters. Where your sword is pointing is the direction we are heading in."

"??? Secondary illness?" Shi Hao couldn't help crying, and said: "The answer to this needs to be found and verified by yourself, and practiced in combination with the actual situation of this world. It is better to have no books than to believe in books. Understand?"

"Understand! Understood! Understood! We will not let you down." Shui Yan said.

Seeing Shuiyan's appearance of having obtained a peerless martial arts secret book, Shi Hao really couldn't laugh or cry.
