Luo Lun was stunned for a while, he didn't expect Kitty's status in Class C Class 9 to be so high!

However, Loren's reaction was also very fast, and after seeing the guy named Tim hiding his face and crying and leaving, he immediately turned around and sat on the chair closest to him, and said to Kitty: "Hehe, I'm sorry, I'm a little short-sighted, I have to sit in the first row." ”

"What are you doing?" A burly, majestic and powerful male student asked angrily.

This chair belonged to him, and it was suddenly occupied by Luo Lun at this moment, which made this male student, who was born with a hot head, very angry, and his fists clenched and clenched.

"I want this seat." Loren said in a calm voice.

"Say it again." The man with the head of the board was furious, the muscles of his right arm were bulging, and the green tendons were rising, and the school uniform was propped up to the brim.

Obviously, this is a muscular guy who has been delayed by the construction side to learn the combat side.

Click! One Jinna was left on her desk.

The man's face froze.

The second Jina spun around on the table.

"This is the outlet! Young Master Luo Lun, please take care of it, you can lie down, hehe......" The man with the inch head squeezed out an ugly smile from his face, and put away Jinna with a smile.

Kitty didn't get angry, but giggled and said to the girl who was sitting at the same table as the man with the head of the board, "Let you make a seat, do you need Jinna?" ”

"No, Kitty Beauty, you can sit casually!" The girl immediately stood up like an electric shock and quickly vacated her seat.

Loren smiled bitterly in his heart, he still underestimated Kitty's status in Class C Class 9.

The morning class sounded boring to Loren, but the presence of the beautiful Kitty next to him made him dare not doze off. Although Kitty looks normal, there is always a feeling that she will swallow herself at any moment.

After class, Loren hurried back to the dormitory, and then he received the good news that Walkerman, the tutor his father had hired for him, had been discharged from the hospital.

Workman is an intermediate tutor in the college, and I heard that he has been applying for the title of senior tutor, and his theoretical knowledge is extremely solid. was originally a person with a good temper, but he was angry with Luo Lun's "talent" and entered the sanatorium.

However, it seems that Workman is cultivating well, and even after hearing that Loren still failed in the latest promotion assessment, he only rested for a few more days before insisting on being discharged.

As long as there is money in Longxiang Academy, each student has the right to hire a private tutor, and the private tutor can issue a "personal tutoring certificate" to exempt the student from taking professional classes. This is excellent news for Loren.

Loren immediately said that he would study hard with Workman wholeheartedly and never be lazy, in exchange for a "personal tutoring certificate", which was sent to the supervisor of the C class before the afternoon class.

Finally escaped Kitty's clutches for the time being, but public classes cannot be exempted with a "personal tutoring certificate", and every student must go to it, which is unavoidable.

It seems that Workman made a study plan for Loren during his recuperation, and immediately after he was discharged from the hospital, he handed Loren a list and asked him to smelt the necessary metal material for making vehicles in two weeks.

Each of the theoretical derivation steps, the formulas involved, the source material and the test methods are clearly reflected in the list. All Loren had to do was memorize it and follow along, to the point where practice makes perfect.

Smelting Pang metal is a threshold for students on the construction side, and if it can be smelted independently, it means that at least a passing score can be obtained on the construction side.

The achievement of pangmetal cannot be obtained by rote memorization, and the fusion of four base metals, namely copper, tin, lead, and iron, is still required, but the smelting formula is varied. According to the environment, temperature, humidity and other conditions at the time of smelting, these are uncertain factors in the real examination room, and it is necessary to rely on the on-the-spot strain of the candidates.

This requires a solid foundation of knowledge and experimentation, and luck is a very small component, almost negligible.

In Walkerman's mind, if Loren can succeed in five trials and get all of them, the chances of winning the next promotion assessment will be extremely high, and it will not be in vain that his father Shawner spends a lot of money to hire him.

Standing in Walkerman's private laboratory specially provided for himself, Loren felt more intimate than ever before, which should have something to do with him becoming a junior alchemy apprentice.

The various pungent smells in the laboratory made Luo Lun suddenly feel like he was in the ocean and wanted to show his skills unscrupulously.

The high-grade metals of Mogui are very different, and the main materials for the current construction of Battlestar are piled up with a variety of different high-grade metals, and the transformation and promotion of base metals is the main reason.

But now Luo Lun found that this kind of elemental transformation, which relied on basic formulas and experiments, was extremely inferior in the eyes of alchemy technology.

Alchemy also requires formulas, but now they are deeply imprinted into Loren's mind through the knowledge map, which requires metal elements accurate to micrograms, and removes some extraneous metal impurities.

The basic alchemy skill "Smelting", requires an alchemy formula that is seventeen steps simpler than the one on Walkerman's list, and the base metal conversion process has been optimized, but requires a starter culture.

This starter is not currently mentioned in any of the courses, and is supposed to be an elixir unique to alchemy. Loren experimentally identified a plant and several stone mines he found, and quickly came up with the raw materials for refining the starter culture.

Fortunately, there is all the equipment in the laboratory, which can meet the work of Loren refining starter culture very well.

When Workman saw Loren concentrating on tinkering in the laboratory, he left with his hands behind his back contentedly, and told Loren to ask questions if he encountered a problem.

After experimenting with and damaging a plant, Loren refined the starter after three days, and then he began to "melt" the base metal.

On the fifth day of Walkerman's assignment, Loren produced the first piece of pangmetal, a speed that even Walkerman, who had first come into contact with pangmetal.

Of course, Loren was not prepared to be exposed. He hid the piece of pangmetal and continued to refine it for the second time, then the third and then the fourth......

There are many base metals in the laboratory, and there is no shortage of these common raw materials.

What Luo Lun had to pay attention to was the smelting of the stone mines he had found so far, he had refined enough starter culture, and learned from the knowledge map that a crystal was of great help to him at this stage.

This crystal is called pink quartz.

Through pink quartz, a small amount of formula and base metal transformation can be used to quickly smelt Pang metal, which can be said to be completely unimaginable in this world at present. In addition, properties such as hardness and durability are also the best known grades.

As Loren began to prepare for the secret refining of pink quartz, the two-week time limit mentioned by Workman was over, and the old man appeared at the door of the laboratory with an anxious face.

The two weeks he had set at the beginning were actually trying to take care of Loren as much as possible. According to the usual understanding, knowing all the steps and formulas, and having all the raw materials, Loren should have arrived at Pang Metal within ten days. However, two weeks had passed, and he hadn't received any news from Luo Lun about refining Pang Metal, not even a single inquiry about the problem.
