A cemetery was deliberately opened up in the depths of the ruins to bury the brothers who died in battle, Yi Xuan announced that he would not go out for the time being, and only sent sporadic sentry posts every day to reconnoiter the movements of nearby demon cultivators, and the spiritual objects seized by the previous extermination of several demon cultivation forces were piled up, which was enough for all members to concentrate on improving their cultivation and supplying Mapo and others who had set up shops in Longteng County, and the people who stayed in the Penglai jungle of the Trap Realm also needed to be transferred to the station in batches as soon as possible, entering a relatively gentle stage of development.

Yi Xuan's previous clean-up operations caused an uproar in the Demon Cultivation Realm opposite Deshi Mansion, and several powerful Demon Cultivation Forces were completely wiped out, and the last Golden Crow Hall even damaged a Demon Cultivation Yuan Infant, which made the Demon Cultivators who were already eager to repay the same enemy, and entangled the large and small forces to invade the cultivator forces on the side of Deshi Mansion, and the two sides fought back and forth, and the war heated up suddenly. It turned out that the deserted prison spirit mountain station was also often seen with monks from all walks of life passing by, and the atmosphere in the station became solemn.

When the iron guard inquired from Anshu City and reported the news to Yi Xuan, this made him understand the reason, and he couldn't help but shake his head and smile bitterly, so he could only temporarily stop the people escorting the Penglai jungle to avoid unnecessary casualties. More than 100 people were bored in the underground ruins all day long, and they could only bury their heads in penance, especially some monks who were seriously injured in the battle with Jinwutang, but they also gained a deep understanding, and many of them were greatly improved after recovering from their injuries.

Since the natal flying sword was still being upgraded, Yi Xuan had nothing to do, and under Xiao Zhong's reminder, he reproduced the Dayan sword technique of the day in his mind all day long, and after gradually finding the feeling, Yi Xuan began to try to practice the sword technique of driving again. Since there were no flying swords available, Yi Xuan could only simulate the sword technique completely with his spiritual sense, first outlining the basic runes related to the eight flying swords "Qian, Kun, Xun, Zhen, Kan, Li, Gen, Dui" with spiritual power, and then trying to fuse the eight runes together to form the prototype of the Dayan Sword Technique.

At that time, when refining the flying sword in the eye of the sea, Yi Xuan had already mastered the eight runes, but the depiction inside the spiritual object was completely different from sketching out of thin air, not only did it require the exact score, but also the eight runes had to be completed in one go before the next rune fusion could be carried out. With this first step alone, completing the depiction of eight runes was already stumped for Yi Xuan, and every time he completed up to four or five runes, he was already dizzy, and the slightest distraction would be wasted.

In fact, Xiao Zhong didn't know that this move was not a move that could be completed in the Jindan period at all, but whenever Yi Xuan thought of the scene of the battle with the Black Feather Ancestor and the brothers who died in battle, he made up his mind that he must complete the deduction of the Great Yan Sword Technique.

Time flies, like a white horse passing through a gap, in the blink of an eye, half a year has passed, during which Yi Xuan has been closed, studying the Great Yan Sword Technique every day, and meditating to nourish his mind when his spiritual sense is exhausted. Repeatedly, he could only sketch four or five runes from the beginning, until he could calmly complete all eight runes, but the last step of rune fusion was even more difficult, and Yi Xuan tried thousands of times but never got the point.

On that day, Yi Xuan used the Great Yan Sword Technique in an epiphany, which was itself a state of seeming to be awake but not awake, and now he wanted to desperately recall the scene of that day but it was always hazy, as if his eyes were covered with a layer of mist, and whenever he was about to master the essentials, he would wake up from meditation with a splitting headache. Yi Xuan endured the severe pain, continued to retreat into meditation to recover his spiritual sense, and then made the next attempt. Although it failed to succeed once, its spiritual sense has been continuously tempered and then rapidly improved, and the degree of condensation is comparable to that of a monk in the early stage of the Yuan Infant, although it is impossible to practice the Great Yan Sword Technique, but all kinds of spirit runes or sword moves that he has mastered before can be used at will, and there is no need to pretend to be a rune paper or a flying sword, and the power is only stronger than before.

On this day, Yi Xuan woke up from meditation again, and did not recall the process of this realization, but suddenly remembered every movement, every gesture, and even the expression and tone of the Venerable Dayan in the message transmitted by Xiao Zhong at that time, and subconsciously Yi Xuan imitated the scene when Venerable Dayan created the sword technique, and with a slight stroke from left to right with his fingers together, all the furniture in the quiet room was cut in two by him from the middle, and then Yi Xuan said to himself. I, the Venerable Dayan, is also, observing the evolution of the celestial body for hundreds of years, now comprehending the mysteries, creating a set of sword tricks, named the Dayan Sword Trick, the earth strategy 210 has six, the heaven strategy has 4 out of 140, and the two strategies change 1,520, when the number of all things is also. ”

Yi Xuan's hands quickly outlined eight Zhongyan runes, held them in the palm of his hand at the same time, stirred and kneaded, and fused the runes together like kneading dough, forming a mysterious and abnormal sword-shaped rune, the shape was the same as the huge flying sword formed by the fusion of eight flying swords at that time.

Yi Xuan opened his eyes and smiled knowing as he looked at the sword-shaped runes suspended in mid-air, the Great Yan Sword Technique had finally been practiced under his sleepless persistence!

Carefully looking at the sword-shaped rune in front of him, Yi Xuan found that it could actually absorb the surrounding spiritual power to maintain its own consumption, and as long as the spiritual sense was close to the rune, it would also be inhaled by it, which was as domineering and strong as "Great Evolution Spirit Decision". And unlike ordinary runes, which can only give one target and hit with one blow after being excited, the sword-shaped runes are more like flying swords, echoing Yi Xuan's spiritual sense, and can fly up and down in the quiet room according to Yi Xuan's ideas, and the agility is abnormal.

Taking out a piece of rune paper, Yi Xuan wanted to try to print the sword-shaped rune into a dao rune, but he didn't want the rune to just touch the rune paper, so he ignited the rune paper and turned it into a pile of ashes, Yi Xuan took out a few more demon beast leather tests, and was also swept into ashes by the sword-shaped rune's domineering sword qi. After experimenting with several spiritual objects in a row, all of them were destroyed by the sword-shaped runes, Yi Xuan simply took out the spiritual objects around him one by one, kept trying to fit with the sword-shaped runes, and finally inadvertently threw out a nine-star full-level Guiyuan Dan, the sword-shaped runes actually drilled into it like a swimming fish, and the Guiyuan Dan was restored to its original state with great light, but it could be seen that there was a sword-shaped rune floating faintly inside.

Yi Xuan put the Guiyuan Pill that fused the sword technique in the palm of his hand and looked at it carefully, and couldn't help but fall into deep thought, fortunately, all the nine-star pills that he had refined before were properly preserved, and there were still more than twenty pieces available in his hand;

Thinking that the power of the sword pill could not be tested in the quiet room, Yi Xuan's mind turned and disappeared in place, a few flashes appeared on the ground above the ruins, and several iron guards stationed next to Yi Xuan's residence vaguely saw a figure flashing, but disappeared in a blink of an eye, and couldn't help but be a little surprised, and silently notified all the iron guards to start a careful inspection with a code, so as not to be mixed up with the spies and enter the place without noticing.
