Comprehensive Affairs Bureau, underground training room.

As Zang Si pulled the pass, the door of the unknown alloy opened on its own, and she carried a large suitcase and entered with Zuodao.

When the two of them stepped in, the sensor lights in the training room automatically lit up, and the whole picture of its metallic silver and white simple style also made Zuo Dao at a glance.

There is nothing in the room except for a long table on the corner wall.

Strangely, Zuo Dao stepped forward to check and found that the table seemed to be firmly welded to the ground, and he tried to force it but did not move at all.

Seeing the teenager exploring around, Zang Si introduced in a timely manner:

"All the materials here have undergone special processing, not only in terms of physical defense performance, but also in anti-mystic processing, in short, in this place, it is very difficult to seriously damage or radiate out through mystical power."

"This will be your main activity in the coming month, you currently lack many basic skills, this is your shortcoming, what we have to do is to try to master as many techniques and knowledge as possible when you compete."

As he spoke, Zang Si picked up the terminal and operated it.

At the same time, Zuo Dao heard the sound of the table on the wall, and then moved on the ground with a very slight mechanical sound, and each time the trajectory of the movement was in front of it, the ground would crack out of the guide groove, and the place where it left would be perfectly closed, and finally came to Zang's body.

"That's taller than my tech tree, at least in terms of applications?" Zuo Dao thought with interest, then squatted down and touched the smooth ground with his hand, and found that there were no cracks.

"The first time I came here, I was like you, this is not only the crystallization of technology."

Zang shook his head without explaining much, and motioned for him to come over quickly.

Coming to the long table, Zang Si put the suitcase on the table and opened it, and took it out in turn, which was a square black crystal, a stack of paper, a transparent vial with green liquid, and finally a plant with straight branches but branches and leaves like swirls and entanglements.

After placing it, Zang asked the young man:

"How much do you know?"

Zuo Dao looked at these items, except for the spirit paper that could not be cooked, and the minerals that were judged to be a certain crystal, he did not have any impression of the previous master, nor did he have a comparison of the previous time.

"I don't know anything other than this." Zuo Dao pointed to the spirit paper and said truthfully.

"It's normal, Huayu has a strict knowledge blockade of mysteries, even if the internal materials are controlled and known most of the time, well... Except for the gang of Derivatives. Zang said with a slightly vague brush.

Immediately she began to introduce, she first picked up a fist-sized black crystal and weighed it:

"This thing is a broken magic crystal, a mineral, and it is also synthetic, but no one has mastered the synthetic formula except for a certain department in Huayu, it is the current mainstream material, and it is often used as an ammunition component for all kinds of thermal weapons, and some people will also use it to mix it into weapons, which will naturally have mysterious lethality, and the effect is related to purity.

"Normally, if we go out on a long-term mission, that is, when we can't immediately return to the headquarters to replenish materials, most of us will carry a copy of this mineral, as long as it is applied properly, whether it is to arrange traps or make a simple defense circle, it can be used, if you can study weapons science, you can also be self-sufficient, as for the application method, you will learn later, now the cost performance is too low."

Seeing Zuo Dao nodding intently, Zang Si put down the Broken Demon Crystal, picked up the stack of papers and shook it:

"This is estimated that you know, because it belongs to post-processing materials, there is no specific scientific name, we like to call it life-saving paper, the main use, is in the place where the electronic equipment of anti-mystical processing can not operate, through it, you can achieve the transmission effect, it looks very ordinary, but it is a good thing that can save lives and transmit intelligence at critical times, and the rest is the special material when writing some special content."

Zuo Dao, who entered the state of a student and worked hard to learn knowledge, but soon he reacted and was stunned:

"Hmm... Wait, post-processing? Team leader: You say it has a synthesis method? ”

For a time, Zuo Dao's heart was rarely impacted.

"Yes," said Zang as a matter of course:

"Synthesis will also be divided according to the materials consumed, for example, the purity of Hasaka's internal production is generally cost-free, if the materials used in the production are not good, it may fail in some occasions where the "interference" is very large, and in the same way, there are some content that will have a mysterious reaction even if it is written in words, and it also needs high-purity 'life-saving paper' to carry it. ”

Listening to the introduction, Zuo Dao even wanted to immediately find out the spirit paper obtained when he was on Huaiyang Road and Duan Qiang's spirit paper for analysis.

"I can't find any traces of processing at all... . Zuo Dao recalled, and the deity burst into a foul mouth in his heart.

Immediately—

It's a great heat.

"It's no exaggeration to say that when the scarcity of spirit paper is not an obstacle, give me a few more years to raise the stage of soul forging to the next level, and I can completely get a paper spirit with a city population... Self-detonation with a sea of paper can drown the opponent to death. ”

Seeing Zuo Dao's rare stunnedness, Zang laughed:

"You don't think this thing is natural, do you?"

The left path that came back to his senses continued to resume playing, scratching his head a little embarrassed:

"Yes."

"So now you know?"

"Hmm."

"Then let's continue," Zang put down the spirit paper, picked up the remaining two, and shook the bottle in his left hand first:

"This is what I want to tell you today, about the last of the "three major pieces" we commonly use, my left hand bottle is the right hand of the plant's quenching base liquid, the plant itself is called 'ring leaf grass', direct chewing also has the effect of promoting wound healing, when quenched out, through the preparation and processing, it will become all kinds of healing, detoxification, and raw materials for related medicines.

"These three things will be good companions for life until death."

Zuo Dao hummed, indicating that he remembered.

Seeing this, Zang put down his belongings and put them back, lit a cigarette and said:

"To be honest, I was surprised when you made the technique out of the 'life-saving paper', do you know why?"

Zuo Dao thought about it quickly, and finally said:

“... Because of the consumable type? ”

"That's right," Zang cried, puffing out of his cigarette:

"Consumable techniques are always hard to come by, as you already know, in fact, as long as things related to mystery, there is a price, and most of the time the cost is ourselves, but the consumable technique, just like its name, is the price itself."

As he spoke, Zang Si looked serious:

"This is actually a very terrifying technique, when others are still worried about the battle, because there are too many rituals and techniques, either the immediate negative cost will produce a violent death, or when the battle is separated, how to hold on to the weak period, but you are like a nobody, catch up and give the other party a final blow... Therefore, the master of the expendable spell will always be the enemy's greatest nightmare.

"It's even more precious than creating a ritual on your own, and it's a testament to your talent, the only problem is—

"Whether the technique in your hand can still be improved, but you don't need to tell me this, you can keep it secret, I will make a record for you and submit it, if you like the right in the future, you can completely enrich this technique and hand it over to Huayu, I think even if it is the director of the Comprehensive Affairs Bureau at that time, it will not be a big problem."

Zang said.

"Thank you, team leader," Zuo Dao said seriously.

"So after the gossip, let's have some warm-up activities." Zang cries out the cigarette butt.
