The night before the trainee trainee exam.

In front of the desk shrouded by the lights of the warm yellow platform, Jiang Yifan closed the book and tried to recite softly the knowledge points he had just read:

"The mucus secreted by the Flameburst bullfrog contains a 'host defense peptide' that can effectively defend against cold toxins.

If it is mixed with herbs with 'warming' properties such as fire fruit, scorching grass, and burnt soil, you can make a 'cold repellent'.

After humans take a small dose of 'cold agent', it can keep the body in a warm state for a long period of time, which is used to resist the cold.

After the demon spirit takes a large dose of the 'cold protection agent', when fighting with the ice demon spirit, even if the skin is cut and the flesh is injured, it will not be easily infected with the cold poison, which will affect the movement speed of the battle.

The process of making the cold protection invented by the junior breeder 'Parker Rosa' of the 'Empire on which the sun never sets' is as follows:

(1) After drying the fire sand fruit with a hot air blower, cut the flesh with a knife and take out the core, grind it into powder, and take 3 grams.

(2) Pierce the middle of the grass with a silver needle, and then drain the juice with a clean glass rod..."

...

After reciting this knowledge point word for word, Jiang Yifan's study of the scope of the trainee cultivator exam was finally completed.

Yes, the exam is going to be tomorrow morning, and he is only studying and memorizing it now, and he hasn't even reviewed.

It's not that he's arrogant, it's not that he's lazy and procrastinating, but that there are too many knowledge points to test.

Although this exam is only awarded the title of 'apprentice', the low level is only the level, and the threshold is not low at all.

The amount of knowledge covered in the exam is basically equivalent to the theoretical knowledge that college students in the training major have learned in four years.

Although there are many aspects of knowledge that do not require in-depth mastery, the difficulty of the exam is mostly only at the level of understanding and memorization.

But it can't stand the sheer number of scopes.

If you want to pass the exam with hard power, not luck, you must write down the influential theories, experiments, and conjectures that have been put forward by the industry of cultivators for more than 100 years, from the past to the present, in order to ensure stability.

Therefore, this is not so much a comprehensive examination of the cultivation of teacher quality, but rather a challenge to memory.

When asked about his participation in the trainee trainee exam, a well-known contemporary breeder replied like this: "If I could swear, then I would be happy to answer this question, but unfortunately not." ”

However, for such an exam, Jiang Yifan only spent half a month to prepare.

He's not a genius.

He didn't really understand many of these things, and just forcibly wrote them down.

So much so that if the question changes slightly, he can't immediately pop up the answer, but needs to spend a long time recalling.

This is obviously a disadvantage for time-bound exams.

However, the mountain people have their own tricks.

"If I didn't have two brushes, I wouldn't be able to spend so much time on games, but I still rank in the top three of the grade in Lingfeng Middle School, a key school with a 100% rate..."

The corners of Jiang Yifan's lips hooked up with a smile, and then slowly closed his eyes.

In the darkness, sink consciousness into the depths of your mind...

As the consciousness sank deeper and deeper, a white light appeared in the darkness that became more and more intense...

At the moment of the light, a tall palace with a metallic texture appeared.

This is the 'memory palace' that Jiang Yifan built in his own mind.

With the help of this palace, he was able to store and extract memories with great efficiency.

It's not a natural ability, it's just a common way for humans to use and explore their brains - palace memory.

The principle is very simple, just transform boring words into dynamic pictures in the mind, and then memorize them in the form of space, so that it will become more difficult to forget.

When he first came into contact with this kind of mnemonics, Jiang Yifan was still in elementary school, and the opportunity was to change the TV channel by chance.

Listening to the miraculous introduction on TV, he was not very old at that time, and he was undoubtedly moved, and he tried for it for a long time.

Of course, the process was not smooth.

But fortunately, he was lucky, and on a half-awake night, he finally grasped that feeling in a daze, and took advantage of the situation to build a simple log cabin in his mind, and initially mastered this set of memory methods.

So from that day on, he became the kind of person who was most annoying to his classmates after the test results came out - obviously everyone usually played together, but he was the only one who killed indiscriminately during the exam.

'Boom-'

As if to welcome Jiang Yifan's arrival, the two magnificent metal doors trembled for a while, and then automatically shrank in to both sides.

After so many years of continuous improvement, the small dilapidated house in my mind is now a building full of science and technology.

After Jiang Yifan's consciousness entered the palace, he quickly shuttled between the various floors.

Soon, I came to a huge room with a plaque that read 'Trainee Trainee Exam'.

As the door opened, you could see that there were many small lattices with various labels on the surrounding walls.

But all but one of the small compartments with the 'cold agent' on it was still open, and everything else was closed.

'Gollum...'

As soon as Jiang Yifan's mind moved, a puddle of steaming fiery red magma appeared out of thin air in the center of the room, and the black-looking 'magma tadpoles' swam happily in it.

Then time seemed to be pressed the accelerator button, and these magma tadpoles quickly grew in size, evolving into 'fire gas frogs', and then continued to grow, and evolved into 'flameburst bullfrogs'.

Immediately afterward, part of the slime on the Flameburst bullfrog's body flew out of thin air, condensing a translucent miniature shield with the word 'peptide' written on it.

Then, not far from the lava pool, a sandy field also emerged.

A few seeds were planted in it, and they quickly sprouted and grew into shrub-like plants with fiery red fruits, the Pyrophora Fruit Tree.

The fruit falls off and floats, and the hot air blower appears out of thin air, and the flesh quickly dries up under the blowing of the scorching wind.

A knife cuts it open, the pits are removed intact, and ground into a handful of powder.

Then, the red soil suitable for the growth of scorching grass appears...

...

It wasn't until all the ingredients for making the 'cold agent' had been prepared that the vintage-style pharmaceutical equipment was long overdue.

And a blonde young man who couldn't see his face clearly began to be busy on the experimental table, and after accurately blending various processed raw materials, a tube of red-colored elixir was completed.

At this point, the entire production process of the cold agent is presented in front of you in a dynamic form.

'Bang dang—'

This dynamic image is sharply compressed in equal proportions and then displaced to the last empty lattice and closed.

"The scattered knowledge points have been written down, and now the final step of integration is on..."

Looking at the closed lattices around the room, Jiang Yifan's thoughts moved again, condensing a blue planet.

Although it looks decent at first glance, if you stare at it for a long time, you will find that there is no life on it.

The planet is still 'dead'.

'Bang Chang-'' 'Bang Chang-''

Suddenly, the lattices on the surrounding walls popped out one by one, and pieces of image memories flew out of them and threw them into all corners of the planet.

All kinds of plants and spirits began to appear vividly in the environment they were suitable for, and then grew and multiplied freely.

And those great people who have left their names in history have also started their own legendary stories...

...

...

In a dimly lit room lit by candlelight, a teenager is busy at his desk.

The smell of herbs fills the air, bottles and cans collide with each other occasionally, and the crisp sound echoes in the quiet night...

His dream is to become a good demon envoy and protect his village from wild spirits.

However, he doesn't seem to have that talent, and the demon spirits he cultivates are too weak compared to others.

However, he did not intend to give up.

Rather, he intends to experiment with a new method of cultivating spirits.

As time went on, the night got deeper and the candle flickered weaker.

Until the last remaining wick was reduced to ashes, the fire was extinguished, and a hazy white light appeared on the horizon outside the window.

Looking at the crystal clear solution in the glass tube, the young man with a tired face smiled contentedly.

Since then, the world's first true potion has been born, marking the official independence of the profession called 'Cultivator' from the Demon Envoy...

...

...

Monastery.

A middle-aged priest with glasses walks around the plantation with a smile on his face, greeting the pea artillery, the wood-based demon spirit that lives here.

Even though it's been eight years, he still keeps track of the pea-shaped shells that are spat on the ground.

It's curious...

Obviously, the appearance of these pea artillerymen is almost the same, but why are these 'shells' big, small, round, wrinkled, gray and white?

If you can find out the secret, you will be able to cultivate the best pea artillery, collect the most perfect raw materials, and make the best pea dishes in the world, right?

He happily imagined the better days ahead.

But he may never have imagined that his exploration of food this time would make future generations hail him as the father of demon genetics.

...

...

'Bang! ’

The door to the laboratory was slammed open, and a middle-aged man with blond hair and blue eyes hurriedly ran in with a suitcase.

He made a low-level mistake.

I forgot to find someone to take care of the 'golden vine' planted in the corner of the lab, so I went on vacation happily.

When he returned, he suddenly remembered that there was such an important work to be done.

Although he knew better than anyone that this pampered plant was basically hopeless after three weeks of neglect.

But he still held on to a glimmer of hope, after all, he had put a lot of effort into that plant, maybe there was a what-if?

However, the miracle did not happen, and he couldn't help but sigh as he looked at the wilting golden vine.

"Huh?"

However, after accidentally catching a glimpse of some blue-green fluff growing on the vine leaves, it caught his new attention.

The 'Penicillin' developed by mistake saved countless demon envoys and demon spirits who were injured on the battlefield in the war.

This saved them from death from wound infections and allowed them to quickly return to the battlefield...

...

...

Until all the images in the grid are put into the blue planet.

The previous dead silence was swept away, and it turned with life.

The originally scattered and disorderly knowledge points were integrated in an orderly manner after being integrated into this planet, forming a complete system.

As long as Jiang Yifan is willing, he can search according to the characteristics of time, climate, geographical location, etc., and quickly extract the information he needs from it.

"Whew..."

After opening his eyes, Jiang Yifan let out a long breath.

By this time it was dawn.

It took him an entire night to integrate the knowledge of the memory palace in his mind.

Looking at the newborn sun outside the window, Jiang Yifan reached out and rubbed his somewhat stiff shoulders:

"It's time to take the test..."
