In the past few days, Yi Qingwei has come to Wind Valley every night to teach her wind balloon skills.

Wind ballooning is worthy of the wind stunt, and the difficulty of learning is no less than asking a person who has never held a pen to draw a grand picture!

Fortunately, Ji Yan's comprehension is too ordinary!

Of course, Ji Yan did not relax his study of refining weapons while studying magic skills, not to mention that the midterm exam was coming.

The exams of the refining branch are very interesting, and the scores are calculated according to the level of the refining weapon. The higher the grade, the higher the score, and those who do not reach the yellow grade will be regarded as failing and will be expelled from the college. Although Huang Pin is the lowest grade, there are many weapons without a grade, so the minimum requirement for a refiner is to refine a Yellow Pin weapon!

Although Ji Yan has been studying refining for a while, she doesn't know whether she has reached Huang Pin or not, so she is a little worried about this exam.

On the day of the exam, Zhuge Jian led them to a new refining room, where all kinds of ores were piled up outside, and dozens of small rooms were divided into dozens of small rooms for the exam.

After the last group training match, everyone knew Zhuge Jianyi's identity, but because his attitude was still plain and kind, everyone didn't feel restrained.

"The rules of today's exam are very simple, everyone starts refining with yellow weapons, and if you succeed, you will continue to refine the next grade, and if you fail, you will stop. You can choose your best weapon to practice, and the exam will take place until the sun goes down tonight. I won't say much if you already know the scoring rules, but now the exam begins!"

As soon as Zhuge Jian finished speaking, everyone took the materials one after another and entered the small room to refine the weapon.

A grade of weapons is divided into three grades: high, medium and low, and the level of Xuan and Yellow weapons is judged by hardness, and the stronger the hardness, the higher the grade. Ji Yan thought about it and decided to use harder redstone ore to refine, on the one hand, the redstone ore is delicate and gentle and not easy to make mistakes, and on the other hand, the hardness of the redstone ore should be up to standard.

Ji Yan found all the materials and began to refine, feeding, melting, and forming in one go. Zhuge Jian Yi carefully inspected her finished product and nodded in motion.

Ji Yan exhaled, and the next one was Huang Pin low-level. The hardness requirements of the low grade of yellow grade are twice that of yellow products, and to understand this problem, Ji Yan decided to choose cuprite and red sand to refine, the hardness of cuprite is 1.5 times that of red stone ore, and adding red sand with a strengthening effect should be able to reach the standard. Moreover, cuprite and red sand belong to the same fire, so they will not clash with each other, and it is relatively safe to refine.

An hour later, Ji Yan handed over the trained sword to Zhuge Jianyi, and Zhuge Jian signaled to Tong Guò after a while.

Next is Huang Pin Intermediate. Ji Yan frowned and came to the place where the materials were stacked, the hardness requirements of Huangpin Intermediate were three times that of the low grade, if you choose too hard ore, the remaining time is not enough at all; if you choose the hardness of the material is not enough, the grade will definitely not be raised!

"Girl, I'll teach you a trick!"

The voice of the machine spirit came from the faint voice in his head, and Ji Yan asked quietly, "What move?"

"With flint!"

Flint! Ji Yan suddenly realized that flint could speed up the melting of ore, so she didn't have to worry about running out of time. However, the molten liquid added to the flint was extremely difficult to control, and Ji Yan gritted his teeth and decided to take a gamble!

Finally, before the sun set, Ji Yan handed over the weapon safely to Zhuge Jian. Zhuge Jian nodded at her with a smile after seeing it, and couldn't help but sigh in his heart, he was really a genius! He even felt that if he gave her time, maybe a higher quality weapon could be refined!

Actually, this is an overestimation of Ji Yan. Zhuge Jian didn't know that in the process of refining Huang Pin's intermediate weapons, Ji Yan had several riots in the melt, and the most powerful one almost exploded!

In the end, it was the machine spirit that reminded her in time to use her mind to control the molten liquid in the zhì ding to barely succeed, of course, this exam gave Ji Yan another layer of comprehension of the refining weapon!xh118
