Coming to the long table, Gu Yu coughed lightly: "Instructor Zhou, student Gu Yu came to report." ”

But I didn't want the old man to have no reaction, and he was completely immersed in the book.

As a last resort, Gu Yu raised his voice: "Instructor Zhou, Instructor Gong asked me to clean the library." ”

The old man didn't raise his eyelids, and waved his hand impatiently: "The tools are in the back storage room, don't disturb me reading!" ”

"What a bad temper!" Gu Yu secretly scolded himself, but he was not bored to the point of reasoning with an old man, rolled his eyes and walked towards the storage room.

After taking the tools, he cleaned the huge library by himself, and he did not resist such a punishment, because in a sense, it was also a kind of practice, and he would have no opinion on anything that was beneficial to evolution.

Because motor neurons have evolved, they are naturally faster than ordinary people, and they clean the library in an hour, and even have the leisure to observe the placement of various books during the cleaning process, and secretly write them down.

After cleaning and putting away the tools, he went to a tall bookshelf from memory, took a few books from it, and then found a table to sit down and read leisurely.

These books are mainly about the refining of equipment and the setting techniques of gem runes.

This is Gu Yu's next plan, it is very easy to recharge the system to smelt equipment and inlay gem runes, he wants to let others know that he has learned this knowledge, so that it is reasonable to take out the equipment, and it will not appear abrupt.

Otherwise, it will be like now, obviously with good equipment, but because you can't tell the calendar, you don't dare to show it in front of people.

Of course, it is easy to use the recharge system to build equipment, in fact, you don't need to master much advanced knowledge and technology, all of this is just for show, Gu Yu does not intend to delay the time of cultivation to study this thing.

The most important thing for him to do is to show others, and at the same time it is enough to know a little basic knowledge.

Therefore, reading the book is only a cursory reading to understand the general principle.

After the invasion of the dark demons and the awakening of the Apocalypse, human beings also discovered that traditional materials would mutate and evolve after being infected by dark energy, becoming new materials that had never been seen before, and the quality far exceeded the material technology mastered by humans.

Therefore, the traditional forging methods are simply unable to refine these materials, even if the most advanced equipment is used, it can only be mass-produced from the lowest materials, and the production of these equipment can only meet the use of the army, and cannot meet the requirements of the Apocalypse at all.

After a long period of research, humans finally discovered a way to refine these materials, and finally developed a furnace powered by dark energy.

But the problem is that ordinary people can't control dark energy, and only the Apocalypse can do it, so the equipment exclusive to the Apocalypse can only be driven by the Apocalypse who has mastered the refining technology to drive the furnace to create it.

However, refining techniques are not so easy to master, that requires a certain amount of talent and then spends a lot of time to learn and master, and few people are willing to delay their cultivation time to learn.

Therefore, qualified forgers are very rare, and excellent forgers who can create high-level equipment are even rarer.

But on the other hand, it is precisely because of the scarcity of excellent forgers and the preciousness of high-grade materials that the price of high-end equipment is also staggering.

For Gu Yu, money is also a good thing, and of course he doesn't mind making a fortune by selling equipment.

He hastily flipped through a few books and roughly understood the basic content, and at this moment, a voice suddenly came from the side: "You are interested in forging and refining?" ”

Gu Yu subconsciously raised his head, and saw that Old Man Zhou came to his side at some point, and nodded with a smile: "Instructor Zhou, I want to try to build equipment by myself." ”

"Build your own equipment?" Old Man Zhou chuckled and shook his head: "It takes a long time to learn, not everyone has that perseverance." ”

"I think I'm fine." Gu Yu replied with a smile: "I thought I had this talent. ”

"Talent?" Old man Zhou smiled disapprovingly, and then walked away.

After a short period of observation and conversation, he could already determine that Gu Yu was just that kind of self-righteous hairy child!

There are many people who think that they are gifted, who see everything as simple, who think that they can become a forger by reading a few books, and once they fail, they will not have any patience to persevere, and they will give up immediately.

He has seen too many such young people.

Therefore, even if Gu Yu came to clean the library on time in the next few days, and then read books all day long, Old Man Zhou didn't take it seriously.

It wasn't until the fifth day that Zhuang Yinyue and others came to the library to find Gu Yu.

As soon as they met, Zhuang Yinyue got straight to the point: "I applied with Instructor Gong, and the team went out to hunt alone, and in just one night, I brought you all to 9% of evolution." ”

"Yes, you promised Instructor Gong a week." Gu Yu suddenly remembered this incident.

Looking around, Zhuang Yinyue needless to say, the current evolution of motor neurons is 10%; Yang Hao's motor neuron evolution reached 8%; Feng Song's sensory neuron evolution reached 7% or higher; Even the lowest Rotten has a 6% evolution of sensory neurons.

If the team goes out hunting alone, it is indeed possible for all members to become stars in one night.

Noticing what Gu Yu's gaze was pointing at, Zhuang Yinyue nodded affirmatively: "You also saw it, they are fine, how are you?" ”

"Interneuron evolutionary degree 7%." Gu Yu replied calmly.

"Then there's no problem, it's definitely 9% a night." Zhuang Yinyue looked at Gu Yu forcefully: "The only problem is that the dark energy may not be enough, so it doesn't matter, I can lend it to you, and I will return it to me in the future." ”

"Alright then!" Gu Yu thought for a moment, and then asked, "However, do you have to be tonight?" In two more days, will it be okay to get stuck on the last day you promised? ”

"Why?" Zhuang Yinyue was stunned for a moment.

"I learned a little bit outside of the classroom." Gu Yu smiled and pointed to the name on the book cover: "If you use these two days to create a few pieces of equipment for everyone, the hunting efficiency will be higher, right?" ”

"You learned blacksmithing?" Several people present exclaimed at the same time, looking at Gu Yu as if they were looking at aliens.

"Don't believe me?" Gu Yu smiled faintly.

"It's not unbelief!" Several people showed contempt at the same time: "I don't believe it at all!" ”

It's normal for them to have this kind of thought, Gu Yu has only been reading the book for a few days, and he has proudly said that he wants to build equipment, and the ghost believes it!

Gu Yu didn't refute either, got up with a smile and put the book back on the shelf: "Try it, anyway, it's not in a hurry for a day or two, right?" ”
