In the curriculum of No. 15 Middle School, there are three types of plant-related courses, namely agronomy, botany, and plant practice.
Cheng Han likes the third course the most.
The total class hours of this course is almost the sum of the previous two.
This fully reflects the practical teaching philosophy.
Today's plant practice class, the theme is - soft vine.
at this time.
In a small botanical garden on campus, wooden frames are neatly set up on the fields, and green vines climb on them, turning the place into a vine forest.
A bald teacher was talking eloquently: "I think everyone should know that soft silk rattan is the most important raw material in the textile industry.
"Peel off the skin of the cane, pull out the core, and hit it repeatedly with a wooden hammer to get a slender and soft 'soft silk'..."
The students stood in the vine forest and listened carefully to the teacher's words.
Cheng Han listened very carefully.
In another time and space, cotton was the most common textile raw material.
But in this world, humans have actually made use of vines and used soft silk fabrics, which are no less soft and breathable than cotton.
"Please remember that if the growth time of the soft silk vine is too short, the yield of the soft silk vine will be low, which is not economical.
“If the growth time is too long, the soft silk produced will become too tough, and the fabric will be harder and less comfortable.
"According to experience, the optimal growth period of soft silk vine is five to six months..."
At this moment, Cheng Han suddenly felt his heart throb, and an illusory scene appeared in front of his eyes.
After a while, the illusion dissipated.
A message immediately appeared: "Proficiency +2, current proficiency is 70/1000, and mental value is 6.4/13.8."
This is another passive activation of the All-Seeing Eye.
Cheng Han looked at a classmate beside him and shouted urgently: "Liu Wenyou, give me the knife."
In this practical class, because the students needed to learn how to handle soft vines, the teacher handed out twelve long knives, and Liu Wenyou happened to receive one.
The man was stunned for a moment, then obediently handed over the long knife.
In the past, Cheng Han was just a marginal person in the class, and Liu Wenyou would definitely not look down on him.
But now, he has become a celebrity in the class, his prestige has been greatly improved, and Liu Wenyou instinctively obeyed his words.
This sudden change made the students look over in surprise.
In an almost "grabbing" gesture, Cheng Han picked up the long knife in Liu Wenyou's hand and strode towards a soft vine a few meters away.
The bald teacher was stunned for a moment and asked subconsciously: "Cheng Han, what are you doing with the knife?"
Cheng Han didn't bother to explain and raised the long knife with both hands.
Many people saw this scene and exclaimed.
"Oh my God!"
"What is Cheng Han doing?"
Cheng Han turned a deaf ear to this and slashed hard.
At the same time, he activated the True Flame Remnant Seal.
Extraordinary power came out of thin air, the blade became even hotter, and faintly emitted an extremely weak light, but due to its extremely fast speed, no one in the class noticed.
The next second, something bizarre happened.
The soft silk vine suddenly came to life, and the vine body seemed to have turned into a snake, twisting greatly.
Some branches of the cane, as well as a large number of leaves, quickly gathered together, making a "swishing" sound, and instantly assembled into a group of strange-shaped objects.
It looks somewhat like some kind of animal.
Has a body.
There are also limbs.
There was also a huge head, with its mouth wide open towards Cheng Han, and several rows of sharp spikes could be seen in it.
As you can imagine, if you were bitten by one, the taste would definitely be unpleasant.
At this moment, everyone, including the bald teacher, was stunned.
Cheng Han showed no signs of panic, and the long knife in his hand severely chopped down the soft silk cane.
"Crack!"
The cane was neatly cut into two pieces.
He vaguely sensed that the power of the true flame remnant seal seemed to be rapidly eroding the vitality of the vines.
The vine monster was severely injured, and the branches and leaves all over its body trembled violently, but it still stretched out its head unwillingly, trying to give the enemy a hard bite.
Cheng Han nimbly took a step back, picked up the long knife with his backhand, and struck it again.
"boom!"
The head of the vine monster exploded.
This knife seemed to have caused a chain reaction. Its body disintegrated, and its leaves and broken branches were scattered all over the ground.
It's dead!
Cheng Han stood with a knife in his hand, and his heart started to beat loudly.
This is quite normal.
It was my first time to participate in a battle, so I was a little nervous.
The whole place was silent.
The bald teacher swallowed and broke the calm: "Classmate Cheng Han, was that a 'grass dog' just now?"
Cheng Han turned around, nodded and said, "Yes, Teacher Zhang."
There was a commotion in the crowd immediately.
"It turns out to be a straw dog!"
“I’ve learned a lot!”
The bald teacher's tone was a little frightening: "Vines can turn into extremely aggressive grass dogs under extremely rare circumstances. I never expected that one would be born in the botanical garden."
He showed admiration again: "What Cheng Han did is very correct. A newborn grass dog cannot escape from the vines. As long as the vines are cut off in time, it will die soon."
Cheng Han looked calm.
He knew very well that the key to the knife being able to kill the grass dog instantly was the residual seal of the true flame, otherwise it would still be able to jump around for a while and probably bite a few students.
All the students looked at him with a hint of looking up.
In the eyes of everyone, the first step to discover the grass dog and then draw the sword to kill it is like a legendary story. How can we not make the students yearn for it?
The bald teacher changed the subject: "Dear students, I am very sorry that today's practical class must be suspended. Please leave the botanical garden in an orderly manner and return to the classroom.
"There are grass dogs here. I have to report it to the school immediately and conduct a comprehensive inspection of the botanical garden to ensure that no safety hazards are left."
The students quickly left the botanical garden.
Cheng Han deliberately fell behind, reached out and picked up a leaf left by the grass dog, and then walked towards the door.
The bald teacher noticed this scene and moved his lips, but finally said nothing.
According to the rules, these are relatively sensitive items and should be collected by the school and then destroyed.
But Cheng Han single-handedly killed the grass dog and solved a big problem for the school. The bald teacher chose to turn a blind eye and pretended not to have seen it.
*
Due to a short delay, Cheng Han arrived at the classroom last.
The moment he appeared, the noisy classroom suddenly became quiet for a moment before returning to the hustle and bustle.
Such a posture is quite akin to a big boss appearing.
Cheng Han walked to his seat calmly.
He had only walked a few steps when he heard a voice: "Cheng Han, we were in the botanical garden just now. How did you find the grass dog?"
It is the girl with short hair, Wan Tengjiao.
The classroom became quiet again.
Everyone is waiting for Cheng Han's answer.
Cheng Han was stunned for a moment and replied lightly: "My feeling is relatively keen."
Wan Tengjiao thought thoughtfully: "It seems that your ability to sense source energy is stronger than I expected. Maybe it won't take you long to successfully condense the source energy seal."
Cheng Han smiled: "Maybe."
He had a hunch that he would have a high probability of successfully forming the seal in one month at the earliest and three months at the latest.
Hearing this, the students all cast envious eyes.
Originally, many students privately criticized him for being selected by Qiu Yuan and gaining the qualification to observe Zhenshan Xuanbi, suspecting that most of it was a secret operation.
But his performance just now convinced everyone.
After Cheng Han returned to his seat, Qian Qingqing stared at him with a rather strange look.
Cheng Han asked strangely: "Why are you looking at me?"
Qian Qingqing sighed: "I just discovered today that you are the most secretive person in the class."
