The remaining few books are also about battle cards, and most of them are still duplicates, with only one book about life cards.

But it's enough, it's enough to have an energy card and combat power, and the secret of the Devouring Giant Shield Card can't be exposed for a while, otherwise Guo Feiyu will definitely know that Feng Chen is the murderer.

First, make all the remaining one-star blank cards into energy cards, find an opportunity to sell them, and then buy two-star card materials to make two-star cards.

This matter is not in a hurry, but those shops will not open after the Lanling Festival, this is a rule that has been passed down for countless years, and it has never changed.

Guo Xuan's death was put on hold like this, and Guo Feiyu, who couldn't find the murderer, was already white-headed, getting older and older, and his temper was much more irritable than before.

Four days passed, the Lanling Festival ended, and the students of Tianxing Academy also returned one after another to start the new year's study.

Feng Chen sold all the one-star cards as soon as possible and bought the materials for the two-star cards.

The material of the two-star card costs thirty star yuan, Feng Chen bought two hundred copies at a time, and without the production method of Lan Linka, he can only use the Mu card instead.

Three major card systems, herd cards, star cards, and star wind cards.

These three energy cards are the most commonly used, and the production method is relatively perfect, and the perfect state must be full energy, unlike other production methods, even if the production is perfect, it may not be full energy.

The two-star energy card, the full energy value is 100, and the price is also about 100 star yuan, if it is really perfect, the price still has room to rise.

Two-star energy card, two-star knife card.

There are tens of thousands of two-star cards, and only more than 100 are currently activated.

In the card hall, the sparse light on the shelves of the two-star cards was flickering, and there were too many cards waiting for Feng Chen to unlock.

The two-star stealth card requires a thousand card power to exchange, there is nothing to hesitate, Feng Chen still expects the stealth card to save his life, and exchange it directly.

As for the two-star food card and the two-star storage card......

Each needed 80,000 cards, Feng Chen could only shake his head and sigh, if he wanted to unlock these two cards, it was estimated that he would have to wait until the Year of the Monkey.

Kadian is absorbing Ka Li all the time, according to one hundred and sixty Ka Li a day...... It's going to take almost four years, and we can only hope for a miracle to happen.

Feng Chen found that the further he went, the more Ka Di seemed to need......

It only costs 3,000 to unlock a one-star storage card, and I thought that unlocking a two-star storage card was enough for ten times the card power, but I didn't expect it to increase by more than 20 times.

In the first class of the new year, Nangong Yuxue explained the two-star energy card, and in Tianxing Academy, of course, the Tianxing card was the first to be recommended.

The three basic card systems, it's hard to say which is better or worse, each has its own advantages, anyway, there is not much difference between these three cards on the energy card.

After two hours of explanation, Feng Chen successfully mastered the production of Tianxing cards.

After class, Feng Chen went straight to the library, Lu Fengqian was taught a lesson, and he would definitely not come to harass him again, but Ye Yuxing was afraid that it would be difficult to solve it.

Last time, Feng Chen made Ye Yuxing deflated, but people were always in a hurry, and they were rejected when they took the initiative to challenge, which made Ye Yuxing very uncomfortable.

However, Ye Yuxing is the young master of the Ye family after all, and he will not be as shameless as Lu Fengqian to block the door of the library and prevent Feng Chen from entering.

This time, Xuan Lao didn't stop Feng Chen, and the test first still had some effect.

But in the eyes of Xuan Lao, Feng Chen is still a waste material, without any future at all, and he has only achieved this achievement after three years of immersion in a one-star card, and he really has nothing to be proud of.

Most of the students in the library are first, second and third grades, and only the three-star card is fully open to the public, and the more advanced card books are specially included, which need to be exchanged with student points, and even the two-star card is not fully open.

There were so many students in the library, but Xuan Lao kept staring at Feng Chen, he wanted to see what this waste wanted.

Feng Chen went straight to the two-star card area, and he didn't read any books, opening one was a quick flip through, as long as he touched the new two-star card, the card hall would automatically record, and he didn't have to bother to memorize it at all.

"Is this kid here to make trouble?"

Anger rose in Xuan Lao's heart, he had managed the library for many years, and it was the first time he had seen someone read like this, which was a waste of the hard work of his predecessors.

Which of these included classics is not the result of the efforts of countless people, so they can be read at will?

Everyone else is reading carefully, but Feng Chen is alone, turning the book with a loud sound, not like reading a book, but like looking for something in a book.

After quickly flipping through the first book, Feng Chen opened the second book and continued to flip through it quickly, and the activated two-star cards in the card hall were also climbing rapidly.

"This kid is definitely here to make trouble! Even if he is looking for something, there should be a purpose, he just pulls a copy and flips through it, obviously to make a fuss. ”

Xuan Lao walked over angrily: "Feng Chen, I know that you have achieved the first place in the test, but these books are the work of your predecessors, you are insulting the former sages like this!"

Feng Chen was stunned, he just wanted to quickly master all the two-star cards so that he could participate in the next test, but he didn't expect that in Xuan Lao's eyes, the taste completely changed.

Soon Feng Chen reacted, it was he who turned the book too fast, so Xuan Lao felt that he didn't care, but he had already memorized all the books, and this kind of thing couldn't be said directly, which made him a little embarrassed.

"Old Xuan, I'm also reading seriously!"

"Serious? Seriousness is like you? If you look at other people, it takes you ten minutes to turn a page, and if you finish a book in less than ten minutes, you are called serious? If you want to do this, please leave the library!"

Feng Chen was speechless, how can he leave the library, where are there so many classics besides the library?

"Elder Xuan, please believe me, I'm really reading seriously!"

"Look!"

Xuan Lao was not lightly angry, he didn't listen to advice, and grandstanding, this kind of student really should be expelled!

After Xuan Lao left, Feng Chen continued to read by himself, not noticing that Xuan Lao had been paying attention to him.

As Feng Chen's flipping through the book became faster and faster, Xuan Lao's anger became bigger and bigger.

"How can there be such a waste, three years on the one-star card, get the first place and feel lawless?

There are indeed some geniuses with strong mental power, who never forget the ten lines at a glance, but they don't want Feng Chen to turn the book like this, so that even if they look at ten lines at a glance, they won't have time to see clearly!

What's more, in Xuan Lao's heart, Feng Chen definitely couldn't be that kind of genius!

Feng Chen's unintentional actions made Xuan Lao define him as a grandiose clown who jumped off the beam, and he threw himself on the one-star card for three years just to get a first, which is also wasteful!

When it was time to eat, Feng Chen had already flipped through more than a hundred books, and he had turned over one-tenth of the books about two-star cards in the library, and it only took two or three days to read all the two-star card classics at this rate.

The libraries of the Heavenly Star Academy were all organized, unlike the wild classics that Feng Chen got from the Rat King, there would definitely be no duplicate content in the books here.

More than 100 books, more than 5,000 kinds of two-star card production, if someone can memorize so much content in two hours, it is no longer a genius, it is a demon!

"Thank you, Xuan Lao!" Feng Chen expressed his gratitude to Xuan Lao before leaving.

Xuan Lao looked at Feng Chen angrily: "Don't thank me, I can't afford to be thanked by a genius like you!"

Feng Chen knew that there was something in Xuan's old words, but he just smiled awkwardly.
