From Kunlun Mountain to the Northeast, Su Yan'er has been crying cold. Fang Wuxian knew that she was really a little cold, at first she would try her best to squeeze into his arms, and then with Xiaobai following, the warm stomach became her backrest.

The two also discussed the issue of "cold resistance". It stands to reason that Fang Wuxian and Su Yan'er are both peak cultivators of the third-order Qi Transformation Realm, and it makes no sense that Fang Wuxian is not cold, but Su Yan'er is cold. But the facts were there, when the temperature was about to reach about minus forty degrees, Su Yan'er was a little unbearable, but Fang Wuxian had never been cold.

Of course, the final discussion was inconclusive, and it could only be attributed to Fang Wuxie's special physique, after all, in terms of strength alone, two Su Yan'er could not compare to one Fang Wuxie.

Cold is cold, but whenever something important happens, Su Yan'er will rush to the front. Entering Kunlun and leaving Kunlun, going back and forth for nearly a month, Fang Wuxian felt that he was used to it, accustomed to preparing three meals a day, accustomed to trekking through the snowy mountains through thick and thin, accustomed to seeing her pouting and arrogant demeanor, and used to shrinking into his arms when she shouted cold.

Yes, he was somewhat accustomed to the days when he was by her side.

Fang Wuxian sighed, thinking that if he was by Su Yan'er's side at this time, she would probably not fasten the buttons, but would lean into his arms with a blushing face.

It's a kind of happiness, but it's also a kind of sorrow.

This sorrow stems from his betrayal of Su Su's feelings.

Boom! There was another noise in the trees. Fang Wuxian looked up, Zhang Xiaoxiao had already turned her fingers into fists and knocked on the trunk again. Then he closed his eyes and pondered, not knowing what conclusions had been drawn from such an experiment.

"Alas! Su Su, Su Yan'er, Zhang Xiaoxiao, maybe Guan Li, Tang Xiaoqi, brother has accumulated virtue for several lifetimes, so he will meet so many intoxicating and heartbreaking women in this life! ”

Fang Wuxian shook his head, although the thing of feelings is constantly cut and sorted out, but if Su Su doesn't wake up for a day, what mind does he have to sort out these things?

Fang Wuxian was just about to turn his mind back to studying the ancient tree patterns, when he suddenly saw Su Yan'er raise his head in shock, run a few steps towards the southwest, and then slap his forehead, and looked at him and shook his head.

What's going on? Have you discovered the secret of the formation?

Fang Wuxian wanted to ask, but he was afraid of disturbing Su Yan'er's inspiration, so he seriously looked at what she had discovered. I saw Su Yan'er bend down and search carefully nearby, and after a long while, she seemed to have finally found a clue, and walked straight south for five steps, then six steps to the east, and then turned around and walked ten steps in the northwest direction. In this way, the detour became bigger and bigger, sometimes walking to the west side of the giant tree, sometimes to the east side of the giant tree, south to north and south, east and west, even if he occasionally faced Fang Wuxie, it was as if he didn't see Fang Wuxie's doubts.

No matter how slow Fang Wuxie was to react, he understood at this time that Su Yan'er had not discovered the secret of the formation, but somehow, he was trapped in the formation.

"This formation may be similar to Kunlun Mountain, the formation outside is a trapped formation, a phantom formation, and the guardian may be the gateway that Xiaobai chases into. At this time, Yan'er should have strayed into the trapped array outside. ”

Fang Wuxian had the intention to rescue Su Yan'er, but he was worried that he would be trapped after he recklessly entered the outer formation, and it would be even more troublesome at that time. There is no danger to Su Yan'er now, so it is better to find a way to solve it here.

He stroked the giant tree with his hand, his eyes moved with Su Su, and slowly found that although Su Su was moving from east to west, there seemed to be some vague patterns in his movements, and he felt a little familiar with this rule.

Why does it feel familiar?

Yan'er is trapped in the formation, but why do I think she is breaking the formation?

Formation, what is a formation? It is the most direct description of the Great Dao of Heaven and Earth, Yan'er is in the array, what does she see?

If she is breaking the formation, why does she feel familiar when she is moving?

Fang Wuxian asked one question after another, but none of them could be answered, and in the end, all the questions focused on one point, that is, where did the familiarity between the journeys come from?

His gaze followed Su Yan'er, his mind trying to find where that familiarity came from.

Boom! Zhang Xiaoxiao pressed her palm on the trunk of the tree, and the whole person shot like an arrow to the ice lake more than ten meters away.

If a person is thinking and suddenly sees Zhang Xiaoxiao coming and going so slowly, it is easy to disrupt his thoughts. But to the other party's innocent words, Zhang Xiaoxiao slapped his palm on the trunk of the tree, as if he was drinking on the head, which made him sober up suddenly.

It turned out that his familiarity with Su Yan'er's journey came from the suspicious lines on the ancient trees, but why did it seem that there was a shadow of these lines in the depths of his memory?

"5th South, 6th East, 10th Northwest...... East Seventh, North Eighth ......" Fang Wuxian used the ancient tree as a map, comparing the direction and distance of Su Yan'er's travel. The fingers follow the lines, gradually moving upwards and upwards. This zigzag line is sketched in my mind. The words that Guan Li said when he taught him to set up the formation echoed in his ears: "Casually follow the changes of heaven and earth, and follow the intention of his own heart." When painting, the hand can be casual, but the heart cannot be casual; If the heart is casual, then the intention will not exceed the heart. ”

The hand followed the direction of Su Yan'er's travel, outlining the lines of the ancient tree until he did what he wanted, and then moved as he wished.

If the heart is casual, then the intention will not exceed the heart!

If it does not exceed the rules, it is the law, and the law is the most direct and simple second description of the avenue of heaven and earth.

When Fang Wuxian started, his eyes were still following Su Yan'er, and he could draw the lines of the ancient tree in his hand. But later, he no longer looked at Su Yan'er, his hands moved with his heart, his heart moved at will, and his mind went to understand the laws described in the lines of the ancient tree.

Zhang Xiaoxiao devoted all her attention to studying the power borrowed by the purple electric squirrel and Xiaobai when they left the ancient tree. She couldn't crack the formation, but she understood that since both the purple electric squirrel and Xiaobai disappeared after the last borrowing, the direction in which they disappeared must be the so-called "portal", and the speed or strength of their progress was a necessary condition for passing through the portal.

In fact, Zhang Xiaoxiao's method is the same as that of Fang Wuxie skiing down from the top of the snow peak and hitting the portal. It stands to reason that this method should be Fang Wuxie's patent, but Fang Wuxian had just learned the way of the formation recently, and he was so focused on breaking the formation that he had forgotten the method he had used.

From another point of view, Zhang Xiaoxiao deserves to be the best criminal policeman, it took Fang Wuxian most of the day to think of this method, and she just watched Su Yan'er and Fang Wuxian find a way to solve it for a few minutes and was frustrated, and then thought of this method.

Of course, this method is feasible, Zhang Xiaoxiao first found the general direction of the portal by observing the angle of the purple electric squirrel and Xiaobai when they left. Then, by constantly tapping the ancient tree, he simulated the strength that Xiaobai borrowed at that time, and then calculated the speed used by Xiaobai to rush into the portal.

After continuous simulation, mental arithmetic, and experiments, Zhang Xiaoxiao felt that this time would definitely be able to pass, she took a deep breath, and her true qi started from the dantian, and suddenly rushed up to the twelve-story building, crossed the jade pass, walked the zenith, walked the jade dragon, poured the blue sea, stirred Zhou Tian, and then there was a shock, and in a loud bang, it shot out towards the portal at an unprecedented speed.

Then, Zhang Xiaoxiao arrived in a warm, narrow and bright valley, and I don't know if it was dawn, or if she had changed the space, she saw a purple light, a violent giant ape, and a strange snake fighting with the two.

A giant serpent with two heads.
