In the next few days, except for Mo Wen and Xu Yichen to familiarize themselves with the terrain and cultivation of Tianyan Pavilion, almost all of his time was spent on learning this sword formation.

The difficulty of building this sword formation is very high, and even a bug in the cultivation of a formation like Xu Yichen can't build it in a short time.

Just when Xu Yichen was concentrating on studying the sword formation, there was a knock on the door that was not light or heavy, followed by a young man's voice:

"May I ask if Senior Brother Xu is here?"

Xu Yichen had already entered the realm of ignoring things outside the window at this time, so naturally he couldn't hear the knock on the door.

When the young man saw that there was no reply, he thought that his voice was too soft, so he raised his voice a little and said:

"Excuse me, is Senior Brother Xu here?"

Before the words fell, the door was opened, and when the young man wanted to open his mouth to call "Senior Brother Xu", he found that it was an extremely beautiful woman who came out to open the door.

Naturally, it was none other than Ah Jiu, who was living in a guest room with Xu Yichen, Ah Jiu looked at the weak young man in front of him with interest and said:

"You're here to find Tatsukoshi?"

The young man was attracted by Ah Jiu's beauty, but he didn't come back to his senses for a while, and stood there in a daze.

Ah Jiu didn't look impatient, but spoke again:

"You're here to find Tatsukoshi?"

The young man came back to his senses from his stunned state, quickly lowered his head, and said:

"Back to the girl, I came to find Senior Brother Xu Yichen. ”

"You are?"

"Wu Feng, a disciple of the Xia Tian Yan Pavilion, was instructed by his senior brother a few days ago and benefited a lot, but he found a puzzle that was difficult to answer when he was practicing, so he came to ask Senior Brother Xu for advice. ”

Ah Jiu nodded and said:

"Wait a minute, Chen Gongzi is reading a book, I'll call him over!"

When Wu Feng heard this, he hurriedly spoke:

"Since Senior Brother Xu is reading, I'd better come back to visit another day. ”

After speaking, Wu Feng was about to turn around and leave, but was stopped by Ah Jiu:

"Don't leave yet, Chen Gongzi has read a little too much, and he needs to move, you wait here for a while, I'll call him." ”

Hearing Ah Jiu say this, Wu Feng was naturally embarrassed to refuse, he took a step back, where to wait quietly.

After a while, Xu Yichen hurriedly walked out of the house, and when he saw Wu Feng, he said:

"I'm sorry, Senior Brother Xiaofeng, I was fascinated by reading a book, and I didn't come to open the door in time. ”

Wu Feng hurriedly waved his hand and said:

"No, no, no, it's a little abrupt that the junior brother came. ”

When Xu Yichen heard this, he no longer exchanged too many greetings with Wu Feng, but said bluntly:

"Is there anything that junior brother doesn't understand?"

Wu Feng nodded and said:

"Yes!"

"In that case, let's talk as we go. ”

So, Xu Yichen led Wu Feng to slowly walk around the square.

"Senior brother, at that time, you said that I just thought of attacking Senior Sister Lu's barrier head-on, and I didn't think of bypassing the barrier to attack herself. ”

"Yes, that's what I said. ”

"But there is a problem here, that is, Senior Brother Xu said this because he knew in advance that Senior Sister Lu's barrier was not fully covered, but I don't know at all, in this case, is it the best plan to take such a frontal attack as before?"

Xu Yichen shook his head when he heard this, and said:

"There's no such thing as the best solution, as long as you can beat your opponent, then your method is a good way. ”

"In that case, why did Senior Brother say that earlier?"

"Actually, I want to express what it means that when fighting against others or demon beasts, you need to find the opponent's weak point to attack, take your previous example of competing with Senior Sister Lu, you are not familiar with Senior Sister Lu's exercises, and then the action you take is a direct head-to-head confrontation, do you think this is reasonable?"

Wu Feng thought for a while and said:

"I think it's a little weird, but I don't know what's weird. ”

"Look, when do you need to attack the enemy directly with all your strength like this, it is probably in these aspects, first, there is a huge difference in your strength, so you can directly defeat the opponent with the suppression of this cultivation. Second: It's time to fight hard, and if you don't use all your strength, you'll die. Thirdly, it is when you find the enemy's weaknesses or flaws. ”

Xu Yichen paused and continued:

"There may be other situations, but it is definitely not done without knowing anything about the enemy, if you don't know the enemy's exercises, then you can carry out a tentative attack, for example, you can attack Senior Sister Lu's barrier from many aspects, see her reaction, and then formulate your combat policy according to your judgment, whether to attack the barrier with all your strength or find a way to bypass the barrier to attack herself. ”

Wu Feng nodded and said:

"I know, it's just to find a way to figure out the enemy's reality first, and then prescribe the right medicine. ”

Xu Yichen nodded and said:

"That's pretty much it, but it's easy to say, but it's very difficult to do, after all, the pace of combat is very fast, and it won't give you too much time to analyze leisurely, so you have to improve your ability to analyze quickly. ”

Wu Feng suddenly realized:

"I understand, I know what to do, thank you brother!"

Xu Yichen waved his hand:

"Don't be so polite, if you have any questions, just come and ask, remember, don't go one way to the dark, try a few more roads maybe it will work wonders." ”

"Okay, then senior brother, I'm going to continue cultivating!"

"Hmm!"

Xu Yichen looked at Wu Feng in the distance, and a flash of inspiration suddenly flashed in his mind: Who said that the formation must be drawn by a line, it can start from several points together.

Xu Yichen, who was on the same point, suddenly became enlightened, and the problem that originally bothered him was simply solved.

He smiled and said to himself:

Sure enough, it's not just one side that talks about the benefits of the problem. ”

In the following period, Xu Yichen could be described as a thousand miles in the study of the sword formation, and it took nearly ten days before and after he finally learned the sword formation.

During this period, Wu Feng often came to Xu Yichen to discuss problems, and Xu Yichen was also happy to discuss with him, in Ah Jiu's opinion, their relationship was not like a senior brother and a younger brother, but a bit like a master and a disciple.

However, the peaceful days were broken the day before Wuxiang was ready to use the Heavenly Dao chessboard, and a group of disciples who were sent to purchase supplies were injured all over the mountain and came down to Tianyan Pavilion, and Xu Yichen learned a very bad news from their mouths - Lu Ting and a group of senior brothers were trapped in Huangshiling by a mysterious person.
