Before he knew it, Lin Feng had been in this quiet small room for nearly three hours.

In fact, it doesn't take that long to explain the method of solving the problem.

However, a solution to an equation led to a lot of content, which made Lin Feng feel that Shen Lengxin didn't even know the multiplication formula, and the people in this world had never worked multiplication and division at all, they only knew addition and subtraction. In desperation, Lin Feng had no choice but to write out the content of the multiplication formulas that many elementary school students would know to Shen Leng Xinmo and let the other party recite them.

Fortunately, the other party's learning ability is strong, beyond Lin Feng's cognition, the other party fully understands in an instant, Lin Feng has reason to absolutely believe that if Shen Lengxin appears on the earth, with her terrifying learning ability, any university in the world will definitely be at her disposal.

Although nearly three hours had passed, Lin Feng was sadly surprised to find that there was not enough time at all, and until now he had only just finished explaining the equation operation of the exponent of the unknown number only once, and he had not yet talked about the one-dimensional quadratic equation of the last question! What's more, he couldn't spend all his time here, he had to hurry back to the sect.

Moreover, he had just made such a big move outside, and the people from the Hundred Immortal Sect might come to the door at any time, in case they found out that Lin Feng was here, it would be terrible at that time.

Although Xiao Xueqing had told him that this tavern was not simple, but the other party was the Baixianmen, which ranked first among the three major sects! The strength of the Baixianmen was definitely needless to say, it was absolutely terrifying, and I am afraid that this was not only something that this small tavern could deal with.

Besides, he doesn't have anything to do with this tavern, even if he knows Shen Lengxin, I'm afraid it won't work, and the other party won't necessarily help him. What's more, he can't get over that hurdle in his heart, this matter was originally provoked by him, how can he let the innocent people in the tavern be involved?

However, the Qinglan Sect is different, the people of the Qinglan Sect who are capable of it, how can the Qinglan Sect not protect their disciples, in addition, how to say that the Qinglan Sect is also one of the three major sects, and it is impossible for the Baixian Sect to fight directly with the Qinglan Sect, so it is the safest guarantee to return to the sect by himself.

It's a pity that Lin Feng didn't know the situation of the Qinglan Sect at all, if he knew that the current Qinglan Sect was not taken seriously by the other two major sects at all, he would definitely not return to the sect, because it was very likely that the Qinglan Sect would give up on him as a disciple of the outer court because of self-preservation.

However, there are not so many ifs in reality, and the decision Lin Feng made was just to force himself to death.

Lin Feng, who had made up his mind to leave, sighed slightly, and glanced at Shen Lengxin, although this woman made people feel cold, but the fiery pursuit of knowledge in her heart made Lin Feng admire, you must know that what he explained was generally something that girls hated, but Lin Feng didn't expect the other party to be so interested, and he actually learned with relish, which also just confirmed what teachers often say, interest is the biggest motivation for learning.

As if sensing Lin Feng's strange appearance, Shen Lengxin felt a little surprised, and asked in a cold voice, "What's wrong?"

Hearing Shen Lengxin's question, Lin Feng came back to his senses, sighed and said, "It's time for me to leave!"

"You're not done yet?"

Lin Feng sighed again and said softly, "Next time, I've been away from the sect for so long, and it's time to go back to the sect." ”

This sentence is a bit false, Lin Feng has only been leaving the sect for a short day, and he has not left the sect for long at all. It's just that Lin Feng didn't want to tell the other party the truth, so as not to cause trouble to the other party.

"Hmm. ”

Lin Feng took a few steps in the direction of the door, suddenly stopped, turned around, and said with some slush, "That...before I leave, can you grant me a request?"

"You say. ”

"Can you please show me your face, I don't want to be ashamed to not even know what a friend's face looks like. Of course, if you don't want to, I won't force you. ”

Lin Feng smiled, Lin Feng didn't care about the woman in front of him, whether she was good-looking or not, he was just curious about Shen Lengxin's face, everyone has curiosity, Lin Feng was no exception, he was very curious about what kind of face Shen Lengxin had under that soft veil.

Shen Lengxin hesitated for a while, and finally raised her slender jade hand to slowly lift the mysterious veil gently, at this time, the soft sunlight outside the window shone in, and suddenly a beautiful face gradually appeared in front of Lin Feng's eyes, even if Lin Feng had seen Miao Wuqing's beautiful face, but this fairy-like face made Lin Feng feel suffocated, Shen Lengxin's face was definitely more beautiful than Miao Wuqing.

Lin Feng calmed down the feelings in his heart, and said with a wry smile, "You are so beautiful, why do you always cover your face with a veil?"

Shen Lengxin covered the veil and said coldly, "It's nothing, I don't like others to look at me with that kind of look like you." "However, there is still a word in my heart that I haven't spoken, but I don't know why, I don't hate you looking at me like that.

Hearing Shen Lengxin say this, Lin Feng couldn't help but touch his nose and said with a dry cough, "Okay, I'm leaving." ”

．．．．．．

Not long after Lin Feng left, an old figure instantly appeared in Shen Lengxin's room, exuding an extremely dangerous energy fluctuation around his body, and this energy suppressed the space, which seemed incompatible with the surrounding space, and the terrifying energy was many times stronger than Xu Zheng that Lin Feng met in the back mountain, which showed that this person's cultivation was definitely far beyond the Xuanling level.

Shen Lengxin looked out the window in a daze, as if she knew that there was someone in the room, and said softly, "Old He, why did my chest suddenly feel a little stuffy after that person left just now?"

He Lao looked at the woman in front of him lovingly, this woman in front of him was his master's only child, and he grew up watching it since he was a child, it can be said that his love for Shen Lengxin in his heart is no less than that of her father, and at the same time, it is precisely because of this that his master will send him to secretly protect him.

He Lao listened to Shen Lengxin's words and smiled, "Miss, that's because you are reluctant to let him go." ”

He had been hiding in this room just now, and at the same time, he had been paying attention to Lin Feng, if Lin Feng wanted to make any moves against Shen Lengxin at that time, he would definitely let Lin Feng disappear at the moment when Lin Feng made a move, and not a single bit of scum would remain in this world.

When he saw Lin Feng's lips inadvertently touching Shen Lengxin's lips, he almost couldn't help but move to wipe Lin Feng out, if it weren't for Shen Lengxin secretly signaling him not to make a move, he absolutely believed that Lin Feng had completely died in his hands. Therefore, Lin Feng didn't know that he had just walked in front of the Ghost Gate.
