Chapter 15 [15] Grass Dog

On the Fifteenth High School's curriculum, there are three types of courses related to plants: Agronomy, Botany, and Plant Practice.

Cheng Han liked the third course the most.

The total class time for this course was almost the sum of the first two.

This fully reflected the practical teaching philosophy.

Today's plant practice class theme is – Silk Vine.

At this moment.

In a small botanical garden on campus, wooden frames were neatly erected in the field, with lush green vines climbing all over them, turning this place into a vine forest.

A bald teacher was speaking eloquently: "I think everyone should know that Silk Vine is the most important raw material in the textile industry.

"Peel off the epidermis of the vine stem, then extract the pith, and repeatedly beat it with a wooden hammer to obtain fine and soft 'Silk'…"

The students stood in the vine forest, listening carefully to the teacher.

Cheng Han listened with particular attention.

In another space-time, cotton was the most common textile raw material.

But in this world, humans actually utilized vines, and the fabrics woven from Silk had softness and breathability that were not inferior to cotton cloth.

"Please be sure to remember that if the growth time of the Silk Vine is too short, the yield of Silk will be low, which is not economically worthwhile.

"And if the growth time is too long, the Silk produced will become too tough, and the woven fabric will be hard and uncomfortable.

"According to experience, the best growth period for Silk Vine is five to six months…"

Just then, Cheng Han suddenly felt a throbbing in his heart, and a phantom image appeared before his eyes.

After a moment, the phantom disappeared.

A message immediately popped up: "Proficiency +2, current proficiency is 70/1000, mental value is 6.4/13.8."

This was another passive activation of the Omniscient Eye.

Cheng Han looked at a classmate next to him and shouted urgently: "Liu Wenyu, give me the knife."

In this practical class, because students needed to learn how to process Silk Vine, the teacher distributed twelve long knives, and Liu Wenyu happened to get one.

This person was stunned for a moment, and obediently handed over the long knife.

In the past, Cheng Han was just a marginal figure in the class, and Liu Wenyu would definitely ignore him.

But now, he had become a celebrity in the class, his prestige had greatly increased, and Liu Wenyu instinctively obeyed him.

And this sudden change made the students look over in surprise.

Cheng Han took the long knife from Liu Wenyu in an almost "grabbing" manner, and strode towards a Silk Vine several meters away.

The bald teacher was stunned for a moment, and subconsciously asked: "Cheng Han, what are you doing with the knife?"

Cheng Han couldn't bother to explain, and raised the long knife with both hands.

Many people exclaimed when they saw this scene.

"Oh my god!"

"What is Cheng Han doing?"

Cheng Han turned a deaf ear to this and slashed down with force.

At the same time, he activated the True Flame Remnant Seal.

Extraordinary power descended from the sky, the blade became a bit hotter, and faintly emitted a very weak light, but because the speed was extremely fast, no one in the class noticed.

The next second, a bizarre thing happened.

The Silk Vine suddenly came alive, its body twisting dramatically as if it had turned into a snake.

Some branches of the vine, as well as a large number of leaves, quickly gathered together, making a "rustling" sound, and instantly pieced together into a strange-shaped object.

It looked somewhat like an animal.

It had a body.

It also had limbs.

And a huge head, and opened its mouth wide at Cheng Han, inside which could be seen rows of sharp spikes.

It was conceivable that if he were bitten by it, the taste would definitely not be good.

At this moment, everyone, including the bald teacher, was stunned.

Cheng Han was not flustered at all, and the long knife in his hand hit the Silk Vine stem hard.

"Crack!"

The vine stem was cut into two pieces cleanly.

He vaguely sensed that the power of the True Flame Remnant Seal seemed to be rapidly eroding the vitality of the vine.

The vine monster was severely damaged, its whole body trembled violently, but it still stretched its head unwillingly, trying to give the enemy a bite.

Cheng Han flexibly took a step back, and with a backhand, he raised the long knife and gave it another knife.

"Bang!"

The head of the vine monster exploded.

This knife seemed to cause a chain reaction, its body disintegrated, and leaves and broken branches scattered all over the ground.

It's dead!

Cheng Han stood with his knife, and his heart was now "thumping" again.

Participating in a battle for the first time, it was inevitable that he was a little nervous.

The audience was silent.

The bald teacher swallowed and broke the silence: "Cheng Han, was that a 'Grass Dog' just now?"

Cheng Han turned around and nodded: "Yes, Teacher Zhang."

There was an immediate commotion in the crowd.

"So it's a Grass Dog!"

"Enlightening!"

The bald teacher's tone was a little fearful: "In extremely rare cases, vine plants will turn into highly aggressive Grass Dogs, I never thought one would be born in the botanical garden."

He also showed a look of admiration: "Student Cheng Han's approach was very correct. The newborn Grass Dog cannot break away from the vine. As long as the vine stem is cut off in time, it will die quickly."

Cheng Han looked calm.

He knew very well that the reason why that knife could kill the Grass Dog in seconds was the key to the True Flame Remnant Seal, otherwise it could still jump around for a while, and it was very likely to bite a few students.

Everyone looked at him with a hint of reverence.

In everyone's eyes, discovering the Grass Dog first, and then drawing the knife to kill it, it was like a legendary story, how could it not make the students yearn for it?

The bald teacher changed the subject: "Everyone, I'm very sorry, today's practical class must be suspended. Please leave the botanical garden in an orderly manner and return to the classroom.

"A Grass Dog has appeared here, I must report to the school immediately, and then conduct a comprehensive inspection of the botanical garden to ensure that no safety hazards are left behind."

The students quickly left the botanical garden.

Cheng Han deliberately lagged behind, reached out and picked up a leaf left by the Grass Dog, and then walked towards the gate.

The bald teacher noticed this scene, his lips moved, but in the end he said nothing.

According to the rules, this belongs to a relatively sensitive item, and should be collected by the school and then destroyed uniformly.

But Cheng Han single-handedly killed the Grass Dog and solved a big problem for the school, so the bald teacher chose to turn a blind eye, as if he didn't see it.

*

Because he was delayed for a while, Cheng Han was the last to arrive at the classroom.

The moment he appeared, the noisy classroom suddenly quieted down for a moment before returning to its noise.

Such a posture had the meaning of a big shot appearing.

Cheng Han walked calmly to his seat.

He had only taken a few steps when he heard a voice: "Cheng Han, how did you discover the Grass Dog in the botanical garden just now?"

It was the short-haired girl, Wan Tengjiao.

The classroom quieted down again.

Everyone waited for Cheng Han's answer.

Cheng Han was stunned for a moment, and replied casually: "My senses are more敏锐."

Wan Tengjiao thoughtfully said: "It seems that your perception of source energy is stronger than I expected. Perhaps you will be able to successfully condense the source sense seal soon."

Cheng Han smiled: "Maybe."

He had a hunch that he would most likely succeed in forming the seal in as little as a month and as late as three months.

Hearing this, the students all cast envious glances.

Originally, many students privately criticized him for being selected by Qiu Yuan and obtaining the qualification to observe the Town Mountain Profound Wall, suspecting that there was mostly a black box operation.

But his performance just now convinced everyone.

After Cheng Han returned to his seat, Qian Qingqing stared at him intently, her eyes quite strange.

Cheng Han asked strangely: "Why are you looking at me?"

Qian Qingqing sighed: "Today I realized that you are the most low-key person in the whole class."

Cheng Han smiled without saying a word.
