Whether Guo Huaili agreed to the deal or not, the answer to this question can be found from the math books in his Qiankun bag and the complicated smile on Qin Ran's face.
To discuss whether it was worthwhile to trade his experience in mathematical foundations and application in formations for a loophole in the Wuyin Sword Sect's mountain protection formation, Qin Ran's answer was that it was a huge loss, he was left with nothing.
Guo Huaili brought these things back to Tianji Sect. Within ten years, the strength of Tianji Sect would surely surge, a sustained surge. And Qin Ran didn't know where the upper limit was.
Before this, formations existed in this world as an empirical subject, but after this, mathematics was introduced and formations became a theoretical subject.
It is like studying the formation from a different angle, or like the treasure of the formation has finally found a key, and mathematics is that key.
Basic knowledge like this, something like a trump card, something like a golden finger, something that can bring about changes in the formation, just replaced a loophole in the formation of a small sect.
The most important thing is that if there is enough time, Qin Ran will not need this formation loophole to deal with the Infinite Sword Sect.
Therefore, Qin Ran didn’t have the heart to calculate how much he had lost.
Of course, if one must think positively, then it would be that whether the Tianji Sect was strong or not would not affect him, Qin Ran; and if the Tianji Sect was really strong enough to go down in history, then he, Qin Ran, would be the man with the greatest contribution, the man behind the Tianji Sect, the father of the Tianji Sect.
"After I die, I won't care about the flood."
Qin Ran muttered to himself as he watched Guo Huaili disappear into the darkness.
By the time the Tianji Sect became powerful, he had already left the Immortal Relics Land. What does that have to do with him
… Many years later, Xuan Qin expanded and faced the powerful Tianji Sect. The Prime Minister of Xuan Qin couldn't help scratching his head. Why did the logic of the opponent's formation look so familiar
"Master, are we leaving?" Li Shiyin came over and held Qin Ran's hand.
In front of them, the cloud and mist passage of the mountain protection formation slowly closed in the darkness.
"It's almost done." Qin Ran turned around, took Li Shiyin's hand, interlocked their fingers, and walked back slowly. He said to Li Shiyin, "We were originally planning not to participate in Xuan Qin's plan for the Immortal Dynasty. Now that we don't have to set up a mountain protection formation for Daojianmen, the only task left is to unify Hengduan Mountain.
"Originally, this task would take several years, because the Wuyin Sword Sect is not strong enough, and its internal conflicts are not yet sufficient. Intensifying the conflicts in advance will not achieve the best results. But now that the Sect Leader is afraid of me, let's speed up the process of unifying Hengduan Mountain."
After listening to Qin Ran, Li Shiyin thought for a moment, secretly looked towards the main peak, lowered her voice, and asked, "Master, why don't you..." She made a gesture of cutting her neck with her other hand.
Qin Ran saw clearly that Li Shiyin was asking him why he didn't try to kill the leader and take his place; or just break off relations and destroy both sides, and take over Daojian Sect as well.
… Li Shiyin said, I just asked you why you didn’t try to get rid of the leader, I didn’t think too much about it.
“Why?” Qin Ran smiled, “Because I can’t beat him! The Sect Leader is a great master…”
But as he was talking, he followed Li Shiyin's gaze towards Daojianmen and sighed, "After all, I grew up in Daojianmen."
"And..." He tightened Li Shiyin's hand, "Those things are too tiring. I just want to accompany you and be with you."
The tenderness in Li Shiyin's eyes could not be melted away, and she clung to Qin Ran. She also held Qin Ran's hand with her other hand and called out in a sweet voice: "Master~"
The two of them walked slowly on the grass, their feet gently bending the shallow grass, passed under the sycamore tree, and walked back to the old locust tree.
At the dining table under the old locust tree, Qin Ran and Guo Huaili had not yet cleared away the drinking bowls and chopsticks. Li Shiyin wanted to let go of Qin Ran's hand and go to clean up the bowls and chopsticks, but Qin Ran refused. He grabbed her hand, put his other arm around her waist and hugged her, then lay down on the rocking chair beside her.
The weight of two people made the rocking chair creak in protest.
"We'll wash the dishes later." He hugged her tightly and smiled. His wife was soft and fluffy, like a ball of cotton candy, and once he hugged her, he couldn't bear to let her go.
“Oh my! You really are…” Li Shiyin struggled symbolically but failed to break free, so she let Qin Ran do what he wanted. She leaned her head on his shoulder and complained, “Does it look good to just leave the bowls and chopsticks there?!”
"Wouldn't it be better if you don't look at it?" Qin Ran held her and turned over, looking to the other side.
"Bah! You're so lazy!" Li Shiyin patted him lightly and asked, "How did you survive before I came along?"
"Think about it carefully..." Qin Ran asked in surprise, "Who took care of you when you first came to Danfeng? Do you still remember that you blew up the kitchen?"
“Oh…” After being with Qin Ran for too long, Li Shiyin had already learned how to change the subject. She rolled her eyes and said, “Before, I didn’t know anything, but you were very diligent. I understand now, it’s because I know too much, and you’ve become lazy! Then I’ll become lazy too in the future.”
Qin Ran was full of confidence: "Then let's see who is lazier!"
"Yes, yes, you are the laziest." Li Shiyin was speechless.
The rocking chair creaked gently as the couple snuggled together and looked at the starry sky.
As she was watching, Li Shiyin suddenly remembered something and started to laugh. She asked Qin Ran, "Master, did you suffer a loss when you traded with that formation master just now? I saw that you were in pain and your nose and eyebrows were wrinkled into a pile."
“What do you mean by a loss?” Qin Ran refused to admit it and made a twisted argument. “It’s a matter for intellectuals, how can that be called a loss? I’m broad-minded and have a sense of justice. I spread knowledge and share technology.”
He even said righteously, "I've said it before, if the magic can't be communicated, it will degenerate and eventually disappear. If every master keeps something back, and everyone keeps something back, in the end, this magic will disappear, and there will be no inheritance. So we should be generous in spreading knowledge, culture, and magic."
Li Shiyin touched Qin Ran's chest and said worriedly, "Master, your heart doesn't even beat when you lie now."
"I used to be able to lie with my eyes open," Qin Ran said seriously.
"But Master..." Li Shiyin said, "That formation master Guo is a cultivator from outside the Immortal Relics Land. How can you pass on your formation to him? It would be better if you leave the formation to the people of Daojian Sect."
“What do you mean by outside the Immortal Relics Land or inside the Immortal Relics Land?” Qin Ran scolded, “How can magic have a boundary?”
"Ha!" Li Shiyin sneered, "You just helped Daojianmen destroy Zhishen Valley, and you have always considered yourself a member of Daojianmen. Magic has no boundaries, but you are a member of Daojianmen."
“Alas…” Qin Ran hugged Li Shiyin tightly, “My stupid apprentice has become smarter and is not easy to deceive anymore.”
"I've always been smart, okay?" Li Shiyin said, "I used to give in to you on purpose."
"Ah, right, right!" Qin Ran replied, "It doesn't matter if we lose a little! Suffering a loss is a blessing. We need to quickly deal with the Infinite Sword Sect and then yo-yo as fast as possible. We don't want to wait until the Sect Leader makes trouble and tears our faces apart, which would be embarrassing."
"Oh!" Li Shiyin had lived a very happy life in Daojianmen for more than ten years. She felt sad when she thought that the situation would turn out like that in the end.
"We are only leaving Daojianmen, not the Land of Immortals." Qin Ran said, "We can go to Danyang City to live in seclusion, cultivate to the Nascent Soul stage, refine the elixir of immortality, take the opportunity to have a baby, and then come back to see..."
As he was talking, his expression suddenly changed slightly. He sat up from the rocking chair and looked outside Daojian Gate, into the distant night sky.
Li Shiyin was thinking sweetly about the future as Qin Ran said this, when she suddenly sensed his movement and looked at him, wondering, "What's wrong again?"
Eh? Did she say "again"
Qin Ran looked back at her with a complicated expression, but he was more happy after all. He moved his lips and said, "Someone is here to clean up the mess for us and sort out the way forward."
"Who?" Li Shiyin asked.
"I." Qin Ran answered.
"Um?"
"Um!"
