In the end, Lin Bingru chose to consult Wang Feng'an, although Wang Feng'an was in a very bad state at the moment, he was recuperating, and it was inappropriate to disturb, but Lin Bingru was really stuck and a little uncomfortable.

"It looks like you're not far from success." When Wang Feng'an heard Lin Bingru's question, he knew where she had cultivated, and this was the last step away from success.

This kind of progress is definitely fast, but thinking of the amazing example of Xu Yao completing the construction in a few hours before, Wang Fengan felt that Lin Bingru's speed was not particularly outstanding.

"I think you can ask Xu Yao, maybe he will find a way." Wang Fengan did not give Lin Bingru an answer immediately, but asked her to find Xu Yao.

Xu Yao's ability to complete the construction method in a few hours is enough to show that he has a strong talent in this area, and maybe he can help.

"Ahh

Lin Bingru was also confused by Wang Feng'an's words.

"Go ahead, you will have a different harvest, if not, you will come again." Wang Fengan waved his hand a little tiredly, now he is really tired, and the damage caused to him just now is not small.

At this moment, Wang Fengan needed to recuperate, and he really didn't have much energy to guide Lin Bingru, so he came up with the idea of asking Lin Bingru to consult Xu Yao.

"Okay!"

Seeing Wang Feng'an's state, Lin Bingru couldn't bear to continue to disturb and withdrew from Wang Feng'an's room.

"Classmate Lin, is there something wrong?" Xu Yao looked at Lin Bingru, who was standing in front of him, speechless.

"Well, I can teach you how to draw cards." Lin Bingru held back for a long time and said a word.

Her personality is obviously difficult for her to ask for direct advice, so Lin Bingru will guide Xu Yao first.

"Yes, yes!"

Xu Yao, who was troubled by the complicated card patterns, naturally nodded again and again when he heard this, and at the same time sighed in his heart, "Although this classmate Lin has a cold face, he is a kind-hearted person. ”

"I see!"

Although Lin Bingru's level of card maker is average, it is obviously much stronger than Wang Feng'an's simple tips and rigid books, and Xu Yao is just getting started now, and what Lin Bingru has mastered is just right for him.

After a few days of careful guidance by Lin Bingru, Xu Yao finally successfully completed the production of a mana crystallization card.

Looking at the card in his hand that he had made with his own strength, Xu Yao's heart was full of pride. In the past few days, Xu Yao has eaten and lived in Wang Feng'an's small building, and all his time has been spent on researching card making.

"That classmate Lin, thank you so much for the past few days." For Lin Bingru, who gave him great help this time, Xu Yao repaid the greatest thanks, "That, classmate Lin, do you need my help?" ”

Lin Bingru's favor for helping him clean the classroom last time has not been repaid, and now he owes the other party another one, which makes Xu Yao very unhappy.

"Then you can instruct me on the cultivation of the Fa Constructor, so that everyone can be considered even." Lin Bingru's tone was calm, as if she just wanted to make Xu Yao return the favor, and didn't want to have too much to do with him.

"No problem!"

If this were someone else, hearing such an obvious refusal, it is estimated that he would have left obediently, after all, Lin Bingru's talent, who will guide who is not certain. But unfortunately, Xu Yao happened to have some of his own opinions on the construction method.

Moreover, in the process of instructing Lin Bingru to build the method, can he steal a lesson, the last time he relied on the mana crystallization card, Xu Yao soared a wave of mana reserves, but he is still a 1-star apprentice.

It's like a big bucket with a small hose on it, and it can't get the water out of the bucket quickly.

If you can condense the second mana crystal, then the mana reserves in your body can also quickly turn into combat power.

Seeing that Xu Yao agreed so happily, Lin Bingru was also stunned, and immediately she took out the drawings of the construction method and handed it to Xu Yao, pointing out several difficulties that bothered her.

"It's a bit complicated!"

Xu Yao looked at the few places pointed out by Lin Bingru, these are very critical nodes, as long as these places are done, then there will be no difficulty in the rest.

Immediately, Xu Yao took out a pen and paper and began to disassemble the complex geometric figures of the construction method, explaining while dismantling Xu Yao.

But after he saw Lin Bingru's blank and shocked eyes, Xu Yao remembered that he talked about these geometric mathematics, but Lin Bingru couldn't understand them.

"In that case, you will do as I say, and leave the rest alone." Xu Yao obviously couldn't get Lin Bingru to master complex mathematical knowledge in a short period of time, so Xu Yao only said the answer and asked Lin Bingru to copy her answer.

"Actually, it worked!"

Lin Bingru looked at the paper full of strange patterns in front of her with a dull expression, and the difficulties that had plagued her for a long time were actually solved under these patterns drawn by Xu Yao.

Next, she only needs to follow the above content and cultivate step by step to condense the mana crystal.

"Then let's settle it."

Xu Yao wiped the sweat on his forehead, Lin Bingru is very easy to copy the answers, Xu Yao is not easy to do the question, and it is not easy to reconstruct the simple patterns one by one, which requires some complex mathematical formulas to ensure the consistency of these patterns and no deviations.

The slightest deviation in the construction of mana crystals will lead to failure, so when people practice the construction method, they all complete it in one go, because there will be deviations in the middle of the construction.

However, with the help of the mathematical formulas he mastered, Xu Yao made up for these deviations and made the originally complex construction method simple.

"Thank you, thank you!"

Lin Bingru was silent for a moment, and gently spit out two words.

"Alright."

Xu Yao waved his hand, and after getting along during this time, Xu Yao found out that this classmate Lin was a good girl with a cold face and a good heart. The temperament that rejects people thousands of miles away is just her disguise, remove this disguise, this is a warm-hearted girl.

It's a pity that many people are frightened by her cold aura on the outside, and they can't peek into her true inside.

In fact, Xu Yao was also frightened away by Lin Bingru's cold temperament before, thinking that such an ice beauty was difficult to get along with, but now Xu Yao feels that people like Lin Bingru are very easy to get along with.

"Student Lin, I need to go home, if Mr. Wang asks, you can help me talk about it." After staying in Xiaolou for a few days, Xu Yao also has to go back.

Last time, he promised the cards of those rich children, Xu Yao also had to prepare, and he couldn't release the pigeons. and Hu Shuo also contacted him recently, saying that he had something to look for him.

"Okay!"

Lin Bingru nodded.

Not long after Xu Yao left, Wang Fengan also walked out of the room, and at this moment, Wang Fengan's face had recovered, and it seemed that the injuries of the previous curse had recovered.

"I don't know how those two little guys are cultivating." Wang Feng'an came to the second floor, he was seriously injured before, and he didn't have time to instruct the two of them well, but this time he was ready to teach well.
