Wizard: I Brought the Wrong System

Even though this base was already very magical in Bevin's eyes, it still did not meet the requirements in Yaro's mind.

For example - base infrastructure.

In Yaro's view, the current underground base is still too small. It would be better if it were dozens of floors underground. Otherwise, many sensitive forces will be limited by the principle of 'if you don't know, you are not there', making it inconvenient to conduct research.

Another example - concealment.

The real secret base should be such that no one knows its specific location except those who truly believe it.

But after all, this place was rented from Granny Oak, and its own power level is not enough to support the creation of a base alone.

Another example - security.

Although there was Bud guarding him, he still had to rest alone.

Moreover, Bard's strength is also low. Even if he is awake, if a wizard apprentice really invades, there is nothing he can do to others.

In general, what Yaro wants is the infrastructure of the underground base for biohazard, the concealment of the underground base for research-type rebel ninjas, and the defense of the cave for cautious immortal cultivators.

Unfortunately, Yaro does not have the financial resources to protect the umbrella formula, nor does he have the magic to master infrastructure, let alone the magic circle of early warning, traps, defense, and attack.

Under the current conditions, only this level of underground base can be established.

Leading Bevin, Yaro quickly found Heli in the tool room who was making wooden mechanical fingers.

"Heli, put aside what you are doing and come to the laboratory."

"right away!"

Not long after, Heli pushed open the laboratory door and walked in with her head in the air.

"Lord Yaro, what do you want from me?"

Yaro pointed to the gray-white stones on the ground and said, "Help me research how to purify these poisonous salts."

"Research? I can't." Heli was a little embarrassed.

Indeed, even at the peak of wisdom in a previous life, one would not dare to say that one could pick up a random stone and identify all the ingredients contained in it.

Not to mention that Heli has not studied chemistry yet, and the ‘elements’ in this world are also somewhat abnormal.

Thinking of this, Yaro smiled and said: "It doesn't matter if you don't know, are you willing to learn?"

"Of course!" Heli nodded quickly.

Beiwen hurriedly said: "Teacher, I want to learn too!"

Yaro nodded slightly, thinking about where to start.

The simplest and most direct way is definitely to go directly to the Periodic Table of Elements.

The "Periodic Table of Elements" can be said to be the general outline of chemistry, and even if there are no other details, careful study can yield great gains.

With the help of the magic power of this world, it is even possible to create all kinds of magical magic just like the first volume of the "Wordless Heavenly Book" in the world of Zhu Xian!

After thinking about it again and again, Yaluo decided to save some money.

It was not that he was stingy and he was reluctant to teach the "General Outline of the Chemistry Book", but he was mainly worried about the danger of being a "child with money". After all, Yaro had already made plans to leave in half a year.

Another point is that this is not Yarrow's hometown after all. Even if he really wants to spread the key knowledge, Yarrow hopes that the starting point is his grandfather's territory, and the first people to benefit are the little leeks who have been 'beaten' by him since childhood. them.

Therefore, Yaluo said: "Heli, you have also purified sulfur and saltpeter, and you have a certain understanding of purification. So, can you tell me why dissolution and filtration can remove impurities?"

Although Heli has mastered several purification methods, she has no knowledge of chemistry and can only use her knowledge in daily life to answer the questions.

"This is because... the water... washes away the dirt..." Heli's voice became smaller and smaller, until it was like a whisper.

She herself felt that this statement was not quite right.

Yaro's lips curled up slightly: "The two things you purified before are both insoluble in water and the same are soluble in water. You can't say that the one soluble in water is the dirty thing, right?"

Heli's cheeks turned red and she lowered her head, not daring to look directly.
