At night, Zheng Mansion, West Wing Room, Bai Yunfei's room.

A white light stone held by a small candelabra on the table illuminated the whole room, Bai Yunfei sat at the table, and there were stacks of small books on the left and right sides in front of him, and he was holding one and reading it carefully.

Well, yes, he's 'grading homework'.

It was handed in by the students of the refining class, and it was about their respective perceptions of the last Baiyun Flying Refinery.

Today's class on the mountain behind the Heavenly Soul Academy was generally relatively smooth, and he was worried that he would not be able to teach it well, but when he began to tell the students about the basic knowledge of refining weapons, he found that it was actually very simple.

As long as you express it clearly, those extremely talented students can easily understand it - after all, it is still only theoretical knowledge, and it has not yet involved real refining tools, and those students are undoubtedly outstanding in terms of quick thinking and memory comprehension ability.

At the end of today's class, Bai Yunfei taught the "Flame Control Technique" that everyone in the Refining Weapon Sect would know to those students, this is the best technique for controlling fire refining, and there are some differences with other fire exercises, even some top-level fire techniques cannot be compared with it in terms of controlling fire refining.

But to put it bluntly, it is actually just another use of the fire element force, and it is not a particularly perverted thing, nor is it a secret that is not passed on, since these students are to be taught to refine weapons, then this exercise is naturally to be taught to them.

And the task that Bai Yunfei arranged this time was to let them do their best to master this exercise within a week.

Although the time seems to be a bit harsh, they are not ordinary soul masters, and for geniuses, they naturally have corresponding standards for geniuses.

Bai Yunfei said that if they could master the "Flame Control Technique" to the level of entry, they would be able to practice refining weapons in the next class.

This progress is not many times faster than when Bai Yunfei was learning the refining weapon at the beginning, but who made them 'geniuses'? Moreover, the starting point of their cultivation now is different, the worst is the middle stage of the Soul Sect, which is of course different from Bai Yunfei's beginning.

......

In the evening, Bai Yunfei returned to the academy, and then found Zheng Kai with soul power induction, this guy actually lost a day of his junior sister in the academy, and when he found him, he was very enthusiastic to 'guide' a junior girl to control soul power, Bai Yunfei clearly saw that when he and Zheng Kai left, the little girl looked at Zheng Kai's eyes full of reluctance, and I don't know how this guy did it......

The two of them returned to the Zheng Mansion after having dinner outside, and then Bai Yunfei returned to the room and began to review this batch of 'homework'.

looked at it one by one, but it was much beyond his expectations.

It's not bad, it's better than he expected.

These students' perceptions of his last refining weapon were actually very detailed, and most of them could tell some things that ordinary people couldn't notice at all, such as when how many auxiliary materials were added, and then what these materials looked like, and when the output of soul power changed, how the fluctuations of the refining fire in the Ding changed, etc., they were all able to notice in detail or slightly.

Even Mo Chen's book, which has the least number of words, expresses the extremely detailed process in concise words.

Bai Yunfei even almost suspected that they were simply inner disciples who had been cultivating in the Refining Weapon Sect for a while.

This is also from one aspect, which shows that they do have unique insights and extraordinary insight and comprehension ability on the way to refining, which means that everyone's refining talent should not be too low.

Could it be ...... In fact, they all went to the Refining Sect to do the refining talent test?

Bai Yunfei couldn't help but have such a guess in his heart, and the more he thought about it, the more he felt that the possibility was not small.

......

"Huh?"

Just as he was picking up the last book and flipping through it, he only read a page, when Bai Yunfei suddenly sighed lightly, as if he was greatly surprised by the homework in his hand.

After carefully reading the book with nearly twenty pages in his hand, the surprise in Bai Yunfei's eyes became stronger and stronger, and in the end, it had completely turned into admiration.

It's really ...... It's so detailed!!

From the time he released the Thunder Fire Ding, until the final change in heaven and earth, and the refining of the Heavenly Rank Horcrux, little by little, all of them were recorded!

How many times has the fire refining in Dingnei changed during each process, how much strength was the fire refining, when how many materials were added, what materials were added, what was the order, and what might be the effect......

Not only did he express every step, but he also had some of his own guesses and understandings, and even some small details that Bai Yunfei couldn't remember, which were all recorded.

This 'homework' is completely an analysis and detailed explanation of Bai Yunfei's last refining, even if it is the part where the author understands and guesses, many of them are correct, and they can almost be used as a textbook for refining steps.

After reading it, Bai Yunfei had already decided in his heart: this one, without a doubt, is the best of these assignments.

Closing the book with admiration, when he saw the name on the top page, Bai Yunfei was suddenly stunned.

"Is it him?!"

I saw that in the upper right corner of the first page of the book, there were two words written in a neat font - Night Darkness.

It was actually the sixth-year student of the thunder department who came to Bai Yunfei during the day and said that he wanted to learn refining!!

Only then did Bai Yunfei realize that he had unknowingly reviewed eight homework, and this last one was the one that Ye Ming had given him at the beginning.

He really didn't expect that the homework that satisfied him the most would actually ...... Not their own cadets.

"Alas...... What a pity!!"

Bai Yunfei showed a look of disappointment in his eyes, sighed lightly, and put away all the books on the table.

......

When his soul consciousness swept through the Purple Soul Ring, he suddenly raised his eyebrows and said to himself, "By the way, I forgot about this......"

With a wave of his right hand in front of him, a large pile of miscellaneous items appeared on the table in a slight flash of light.

-- These are the items that were won from the red-eyed young man in the Jin family's gambling house when he finally left.

Lower-grade Yuan Stones, low-grade soul crystals, human-level Horcruxes, and even a few clothes...... It's really a 'clutter'.

However, at that time, Bai Yunfei still agreed to bet on the last game with the other party, in fact, in addition to wanting the other party to completely die, there was a more important reason, that is, he found one of the more 'special' things......

Reaching out and rummaging through the pile, Bai Yunfei pulled out a thirty-centimeter-square 'white cloth' with many black lines on it, like a painting, but it was very messy, and it looked like graffiti.

Bai Yunfei spread out this somewhat shabby white cloth on the table, with doubts and thoughts in his eyes, and muttered: "I didn't expect it, there really is a second ......."
