"Boom!"

In an extraordinarily thick rock hall in the corner of Wuji Palace, a violent explosion suddenly sounded, and billowing black smoke came out of the windows of the main hall.

With such a huge movement, everyone in the palace just looked up calmly, and even those palace maids and chamberlains that Li Yuan brought to serve him were all surprised to look at it for a while, what should they do.

When they first came, they were very frightened, but if they blew up so many hundred and eighty times a day, they would naturally get used to it, but the movement of Emperor Wuji's cultivation of the "Nine Heavens Thunder Method" was a little bigger.

"Ahem!"

Bai Yuqi coughed, and ran out of the laboratory with a gray face on his head.

Shaking his buzzing head and patting the blackened white coat on his body, Bai Yuqi first gave himself a [Cleansing Technique], and then released a [Wind Creation Technique] into the hall to disperse the smoke and dust generated by the explosion.

Walking back to the experimental table surrounded by several stone walls, Bai Yuqi looked at the broken glass slag all over the floor speechlessly, shook his head and cleaned up the scene with [Cleaning Technique], and then took out a set of test instruments again and put them on the experimental table to start the 117th test.

Don't get me wrong, he's not making black powder.

It was just that a certain alchemy material produced an energy saturation reaction during the experiment, which led to the explosion.

It sounds loud, but it doesn't have much power, it's just the effect of energy overflowing.

Although the alchemy experiment is similar to the chemical experiments of later generations, it is after all a mysterious knowledge system, which is closely related to the energy of various elements, and the energy conflict is almost the most basic reaction.

The various arcane knowledge systematically recommended to Bai Yuqi belonged to a part of a complete civilization system, which was both huge and complex.

Research in the depths often has connections with other disciplines, which also forces Bai Yuqi to learn more and more arcane knowledge disciplines.

Even if the system recommended Bai Yuqi with various reinforcement learning spells, he was able to master and understand all kinds of arcane knowledge at a very astonishing speed.

But this is a huge knowledge system of the entire arcane civilization!

Bai Yuqi, who is about to learn to be self-contained, can only choose some content that is not so boring and interesting to him for priority learning, so as to avoid being bored with learning.

Among them, alchemy, runic patterns, construction and other subjects are the parts that Bai Yuqi is more interested in.

After all, these subjects were very similar to the body of knowledge he knew about chemistry, circuits, and mechanics, and it was easier for him to understand.

But even so, this knowledge is easy to learn and difficult to master, and he has been studying for so long, and it still stays at the basic level.

And the most important thing is that these subjects, like the scientific research projects of later generations, are super money-burning!

Take alchemy as an example, it needs to consume a lot of basic resources to refine various alchemy substances, and rune science needs to consume a lot of precious metals and natural spars to produce effects.

This is only the basic stage, and when he reaches some of the materials required at a higher level, he can't even find the corresponding materials...... This is Earth, and you let him go up there to find all those strange arcane materials?

Although there are a lot of minerals in Zhongnan Mountain, the reserves are not large, and after this period of violent mining, they have basically been exhausted.

All the minerals he collected, with the exception of a few that were used to make various items, were basically consumed in his laboratory.

For example, the most basic Arcanon metals, [Alchemy Iron] and [Alchemy Copper], are actually substances synthesized from elemental essence extracted from ordinary iron and copper.

With his current alchemy level, out of 1,000 kilograms of pure iron, only 1,000 grams of [alchemy iron] can be extracted, which is only one thousandth of the refining ratio.

However, this thing is used in large quantities in alchemy, and an alchemy substrate used to burn the rune array may require several kilograms of [alchemy iron].

The amount of [Alchemy Copper] and the rarer [Alchemy Silver] and [Alchemy Gold] may be a little smaller, but the problem is that gold, silver, and copper are also precious metals!

The only thing to be thankful for is that the metal residue that he has extracted the elemental essence is not useless.

Because of the relationship between extraction and purification technology, although these "waste residues" cannot be used for alchemy experiments, they are also high-grade metal materials and belong to secondary Aoneng metals, so they are named [Refined Iron] and [Iron Essence] by Bai Yuqi.

One ton of primary pure iron can be refined into one kilogram of [alchemical iron] and ten kilograms of [iron essence], one hundred kilograms of [refined iron], as well as hundreds of kilograms of iron slag and other trace components.

For Bai Yuqi, these iron slags are useless.

But for Datang Time and Space, these iron slags can already be regarded as high-grade iron materials, and they are good treasures if they are recast and recast!

In line with the idea of waste utilization, Bai Yuqi threw these iron slags to Qi Hui, who had learned some from him, basic alchemy and casting methods.

recruited a group of [Tiangongmen] disciples who knew the skills of blacksmiths, and cooperated with them to process 10,000 sets of "steel scale dragon pattern armor" with assembly line technology, as a gift of unreserved trust in him during this time, and gave it to Li Shimin, who has always been obsessed.

Li Shimin, who received 10,000 sets of invulnerable harness and armor, was like a treasure, Bai Yuqi didn't care.

It was this group of skilled blacksmiths cultivated in the process of building that gave him some ideas.

Although he has designed and manufactured semi-automatic assembly lines, and various lathes, planers, grinders, and other processing equipment and molds with the help.

But it is not easy for hundreds of Taoist priests and thousands of blacksmiths to be able to manufacture 10,000 sets of armor in such a short period of time.

I don't know how they have so much energy to make this kind of armor, which in Bai Yuqi's opinion has no great advantages except for defensive power, and it is called a waste of sleep and forgetting to eat!

Maybe Qi Hui said to them, thinking that this "refining" method passed down by Bai Yuqi was used to test their qualifications, and it was understandable to be diligent and hardworking.

But those blacksmiths also regarded the various metalworking techniques passed down by Bai Yuqi as immortal skills, and what they learned was called a hard and serious one.

Seeing that they were so diligent, Bai Yuqi, who was just planning to use waste, was a little embarrassed, and wondered if he should set up a special alchemy workshop to teach them some real skills, so that he could help himself in the future, so as not to learn the knowledge of the arcane law by himself, and he could only fight alone.
