After that, Qin Di spent another hundred years pondering and practicing the thirteen tricks of sacrificial swords.

However, in the end, limited to the lack of realm, there was still a lack of understanding of the laws of the Heavenly Dao, so he could only perform the thirteen techniques of the sacrificial sword in six forms. However, according to the White Emperor Immortal Ancestor, the six forms were enough, at least able to deal with most of the Heavenly Immortals.

Subsequently, Qin Di applied these sacrificial sword techniques to the sword array, and found that the power of the sword array could suddenly increase many times! The power of the sword array doubled every time he cast a sacrificial sword technique; the power of the sword array increased by four times when he cast the second form; the power of the third form increased by eight times; the power of the fourth form increased by 16 times; the power of the fifth form increased by 32 times; and the power of the sixth form increased by 64 times......

It can be seen that if he can master all the thirteen techniques of the sacrificial sword, he will increase the final power of the sword array to a very terrifying situation.

The clone that Qin Di left in the White Emperor Palace was going to specialize in swordsmanship in the future, so what he chose was neither the four-mouth Zhuxian Sword Formation used by the main body, nor the "Nine Palace Sword Array" that Qin Huo and Qin Mu's two clones used back then, but the "Tiangang Sword Array" with thirty-six immortal swords and the "Earth Demon Sword Array" with seventy-two immortal swords, and directly cultivated the "Zhou Tian Sword Array" with a total of three hundred and sixty mouths!

Zhou Tian's sword formation is not the ultimate in sword cultivation, if it goes up further, there is a total of 999 immortal swords composed of the "Starry Sky Fighting Sword Array", and there are even the legendary 10,000 immortal swords, composed of the "Vientiane Immortal Light Golden Wind Drizzle Sword Array......

However, in the current White Emperor Palace, there is no inheritance of the Starry Fighting Sword Array, at most there is only the cultivation method of the Zhou Tian Sword Array, and with Qin Di's current strength, he can't control so many immortal swords at once, even if there are three hundred and sixty immortal swords, it is already the limit of his divine sense control.

For this reason, he made a special trip to the Golden Wind Valley, and from the thousands of immortal swords planted by the White Emperor, he selected three hundred and fifty-nine sixth-order immortal swords, and also invited the remaining seventh-order immortal swords to use it as the head of the sword array.

Anyway, in the large array arranged by the White Emperor, there are still a lot of immortal swords left, and over time, these immortal swords can continue to grow, and new seventh-order immortal swords will be born in the future.

In order to practice this set of Zhou Tian Sword Formation, Qin Di did not hesitate to retreat for thousands of years, painstakingly and solitary, pondering, contemplating and pondering, and practicing repeatedly, often a drill was several months, and sometimes he also invited the remaining twenty-two heavenly immortals from the White Emperor Palace to come over, so that everyone could work together to fight with him.

At the beginning, the sword array was full of loopholes, as long as the two of them joined forces, they could break through the sword array; later, Qin Di's sword formation became more and more powerful, more and more perfect, as dense as rain, and the wind could not blow, even if the twenty-two heavenly immortals shot together, it would be difficult to break through the sword formation!

After a thousand years of this, the sword formation was completed.

At this point, Qin Di can overstep the level to deal with the seventh and eighth order Heavenly Immortals with this set of Zhou Tianxing Fighting Sword Formation alone, if he adds the method of sacrificing the sword, he is not afraid of encountering any high-level Heavenly Immortals, even if it is a low-level Ancestral Immortal, maybe he can resist for a while.

In addition, for the method of summoning the sword, he also spent a lot of effort to practice, now when the battle, as long as you shout "the sword", the opponent's fairy sword will be greatly constrained, if it is a low-level fairy sword, directly turn the sword body and choose to surrender; if it is a medium-level fairy sword, it will become helpless, stop attacking and killing, and fall into confusion; if it is a high-level fairy sword, there will also be a short period of stagnation, just like a human monk appears in a moment's time, although the time is very short, but for the monk, it may be a fatal flaw.

As for the Qingqiu Golden Formula, Palace Master Jin Mo did not spread it widely, but only selected elite disciples from the White Emperor Palace and passed it down on a small scale.

Zhuang Yunqing, as the personal disciple of the Supreme Elder Tianxian Bai Huan, is naturally within the scope of teaching.

Qin Di specially prepared four sixth-order immortal swords for her as a means of protecting her life.

In addition, she also has a set of low-level fairy swords in her hand, which can be used for ordinary practice.

Zhuang Yunqing had already reached the sixth order of the Spirit Immortal at this time, and he could be regarded as making rapid progress. But even at this point, holding a low-level immortal sword in his hand seemed a little abrupt. Because many ninth-order spirit immortals don't have immortal swords in their hands!

Fortunately, she often stays in the immortal mountain where Bai Huan cultivates, and few people see her cultivating with the fairy sword in hand, otherwise those people will inevitably have envy, jealousy and hatred.

On this day, spring is in March, and spring flowers are blooming.

Qin Di watched Zhuang Yunqing dancing and playing with a sword among the flowers and trees, with a graceful figure, like a butterfly, the sword light was dotted, and the flowers and leaves were not hurt.

When she finished practicing the Four Elephant Sword Formation composed of four sixth-order immortal swords, her white jade-like face was ruddy and smiling, and she asked, "Senior brother, how do you see my practice?

Qin Di said with a smile: "At least seventy percent of the fire, senior sister with this set of sword formations, when she goes out and encounters a heavenly immortal below the third order, she can already win the battle." In this way, I am also relieved. ”

Zhuang Yunqing smiled slightly and said, "That's because the level of the immortal sword that my junior brother gave me is too high, not because the sword formation I cast is powerful." To be honest, as long as I have a sixth-order immortal sword, I can cross the rank and kill the first-order immortals. Now that I have a family of four, what else do I have to be afraid of? My junior brother has taken good care of me, thank you very much!"

Qin Di said: "In time, when Senior Sister advances to a Heavenly Immortal, the power of this sword array will be increased many times. ”

Zhuang Yunqing's beautiful eyes stared at him and asked, "Senior brother, you came to see me today, are you going to leave?"

Qin Di nodded: "In the past, in the ancestral hall, when I worshipped the White Emperor Immortal Ancestor, the Immortal Ancestor hoped that I would go west as soon as possible. I've been putting it off for a thousand years, and now I have everything in place and I'm ready to go. ”

Zhuang Yun rarely showed a trace of affection on his innocent face, and said: "Senior brother cherishes, this is going west, the mountains and rivers are far away, I heard that there will be a lot of dangers, you must be careful." ”

Qin Di asked, "May I ask Senior Sister, after you advance to the Heavenly Immortal, do you want to go to the White Emperor Palace, or do you want to go back to the Four Holy Sects?" My body is still in Luobu Immortal Mountain, and in a few days, he is also going to go to the Immortal Realm, and he may have to wander in the sky for a while, and when the realm is raised, he will find a suitable place to establish a realm exclusive to the Four Holy Sects!"

Zhuang Yunqing groaned: "It's hard to say it now. At present, I tend to go west, go to Kuimu Wolf Star first, cultivate kendo to a high level, and then talk about the rest of the matter. ”

Qin Di said: "That's fine. I have already discussed with Aunt Bai Huan, when you advance to the Heavenly Immortal, you can go on the road with her, and the two of you will be safer together. ”

"Thank you, junior brother, for your thoughtfulness. I will practice hard and not delay Master Bai Huan to go to the fairy world. ”
