Even if Niu Tongtian and the other thirteen people co-starred in the Heavenly Sword, they each studied one of the swordsmanship, and the mystery of it had to be taught by the Green Demon King himself.

Because, the profundity of the Heavenly Sword, if it weren't for the incomparably difficult level of studying mathematics, the stars in the Heavenly Sword Spectrum would only be a mess in the eyes, inexplicable.

Where does Niu Tongtian know that Xu Yi's initial numeracy technique is not bragging, but humility.

As soon as he unfolded the star map, Xu Yi saw that it was extraordinary, and he was addicted to it in an instant.

The esoteric star map, in Xu Yi's eyes, is a number of intertwined problems, and every time a string of beads is strung up, he solves a string of puzzles.

If the Green Demon King was present, he would never have believed that in just a moment, Xu Yi had cracked the entire Heavenly Sword Spectrum to the point that only the last sword technique could not be penetrated.

The last thirteen scattered star points were the last way of swordsmanship, and once they were penetrated, the entire Armillary Sword Spectrum would be completely unraveled.

In the second half of the entire Spring Festival banquet, Xu Yi was basically immersed in solving this Heavenly Sword Spectrum, but he was never able to find a way.

It wasn't until he remembered that Niu Tongtian suddenly changed, and together with the twelve golden armor demons, he performed the Heavenly Sword in front of him, and imprisoned Long Jingtian, that Xu Yi got inspiration.

At this point, while continuing to unlock the last thirteen star points, he reflected the Heavenly Sword deduced by Niu Tongtian and others in his mind, without stopping.

Finally, after thousands of deductions, Xu Yi unlocked the last way of swordsmanship.

Unraveling all the Heavenly Swords, it is like climbing a peak to the sky, standing on the top of the peak, and looking down, you can realize how strange and difficult the road is.

Of course, if it is someone else, if you study it so far, at most, it will only unlock all the key nodes of the Heavenly Sword, understand the sword technique, and undoubtedly there is still a long way to go before you can stimulate the sword moves.

Just like Xu Yi practiced the 357 swords back then, it is one thing to know the sword theory, but it is another thing to stimulate the sword moves and urge the spells.

Fortunately, Xu Yi has the foundation of the 357 swords, the true yuan is boundless, and he has figured out the trick of the Heavenly Sword, if he wants to deduce, he is already handy, and he only needs to regenerate and transform on the basis of the 357 swords.

At this moment, Xu Yi's two swords were used, the sword qi was transformed, and the cage was suddenly born, not only shrouding the old man in the old robe and the middle-aged man in the red robe, but also sweeping the vertical and horizontal sword qi together with Long Jian and Tu Kun and others.

The sword qi rotated at high speed and was invaginated, and in terms of stability and sharpness, it was better than the three-five-seven sword.

Compared with the three-five-seven sword, the most mysterious thing about the armillary sword is that there are more changes in life and death, and between the swords and swords, a sword array is formed, and the power of the field is born.

At this moment, Xu Yi only evolved the two seven thousand swords into the Heavenly Sword, and in an instant, he imprisoned the dragon sword and the big demons such as He Tukun.

The field power of the Heavenly Sword made it impossible for Long Jian and the others to get out of the sword formation at all, and they could only resist tiredly.

It's a pity that Xu Yi didn't point the element, and the fire system true element, which constitutes the origin of the sword array, is too weak in front of the level of the fifth-order demon.

Even with the powerful power of the Heavenly Sword, it has derived powerful spins and high-speed invagination, maintaining stability.

But Long Jian and the others resisted with all their might, but the sword qi couldn't hurt everyone.

After more than thirty breaths, the sword qi of birth and death showed signs of disappearing.

Xu Yi swung out more than ten swords in one breath, and the sword qi in the sky seemed to shatter the entire sky, and the giant sword instantly turned into countless small swords, forming more than ten sword qi cages, once again enveloping Long Jian and others.

"Alright, haven't seen enough, let's go. ”

Xu Yi urged, Feng Jiu woke up like a dream, and a pair of giant wings fanned wildly and swayed away.

In one breath, he flew west for more than 10,000 miles, and never saw Long Jian and other demons chasing him.

bumped into such a demon as Xu Yi, and was bound by an oath, even if he chased him, in addition to continuing to lose face, what else could he do. "Ninth brother, stop. ”

Xu Yi suddenly shouted.

Feng Jiu suddenly paused in the air.

He didn't realize that he had obeyed Xu Yi's words.

In fact, from the time Xu Yi used the Heavenly Sword to the present, he still has some plague and a plague, and he only feels that everything he sees is terrifying and incomprehensible.

Standing on Feng Jiu's back, Xu Yi took out a seal and passed on the news, and half an hour later, a red child with a round head and a round brain jumped up from the waves, it was A carp.

Ah Li jumped in front of Xu Yi and said with joy on his face, "Childe, you finally remembered me, I was so bored wandering alone in the demon domain." ”

Xu Yi pointed at Xue Zihan and said, "This is Sister Xue, my dear friend, and I am also from the Great Yue Realm, and I am from my hometown with you." You've seen it, don't forget it. ”

Ah Li nodded vigorously, learning from Xu Yi's appearance of courtesy on weekdays, and bowed to Xue Zihan with his short and thick little fat hand, "I've seen Sister Xue, my name is Ah Li, I'm very capable, in the future, Sister Xue will never shirk where Sister Xue can be useful." ”

Xue Zihan's eyes were red, and he touched Ah Li's round head, but he didn't speak.

She remembered Qiuwa.

Xu Yi knew what she was thinking, and called Ah Li to approach, and there was an extra talisman in his palm, which was obtained from the dragon sword and the strange talisman of the two minds.

Xu Yi urged the strange talisman, and a cold light instantly enveloped him and Ah Li, and after a while, the cold light went straight into his and Ah Li's chests.

When the cold light was exhausted, Xu Yi suddenly had a wonderful feeling, he called out to Ah Li in his heart, and Ah Li opened his mouth to respond.

Xu Yi smiled and explained the wonderful use of this strange talisman to Ah Li, and Ah Li was overjoyed, "If this is the case, I can receive the child's information without using the seal." ”

Xu Yi got this strange talisman and knew it, and the first thing that came to mind was Ah Li.

A carp's method of water escape is unpredictable, and if it is applied well, it is an excellent helper.

However, it has always been difficult to pass on the news between Xu Yi and Ah Li.

After all, the opponents who are fighting are all big demons, and if they are not careful, Ah Li will easily reveal his whereabouts.

With these two wonderful methods of mind knowledge, it is possible to communicate with each other in the future.

"Ah Li, you go west, I'll see how far away we will disappear. ”

The two hearts know that the different talisman is a rare second-order strange talisman, and the time limit is extremely long, Xu Yi already knows, but he doesn't know how far away it can be.

At that moment, Ah Li fled to the west, Feng Jiu took him and Xue Zihan and fled to the east, and after a stick of incense, Xu Yi suddenly stopped, and asked Ah Li to report the location of the stars in the sky.

He used the starry sky sea observation technique to calculate the distance between each other.

"Eight thousand seven hundred miles, it is very wonderful. ”

Xu Yi secretly admired, and with a thought, he recalled Ah Li.

After a while, Ah Li turned back, Xue Zihan was secretly surprised, and asked Xu Yidao, "What kind of ability is this, he can disappear without a trace in the water, I can't sense it at all." ”

Without waiting for Xu Yi to answer, Feng Jiu preemptively said it first.

Xue Zihan was secretly surprised, she had lived in the Winter Palace World for many years, but she knew the rarity and wonder of the source demon.
