In the past three days, Xu Jingnian has been wandering in the outer area of the sword array.

From the early morning until the setting sun is observed.

He had discovered a pattern, the Lock Demon Tower would tremble three times every time it arrived, and it had been like this for three days.

Whenever the Demon Lock Tower trembled, the eighty-one sword formations would tremble, and even the six Demon Suppression Swords would do the same.

It's not that the big demon is trying to break through the seal, or there is a shocking change inside the lock demon tower, and it is very likely that the sword has changed!

Xu Jingnian can now be sure that the legendary Demon Suppression Sword is in the tower!

But he hasn't found a specific reason yet, so he can only wait, and when the next time the Demon Sword needs a sword element, everything will naturally fall into place.

There are seven more days, possibly shorter, and at this rate of trembling, it will definitely change in less than five days.

Xu Jingnian frowned, this matter is really a bit tricky, now that the sword heart is covered with dust, some methods cannot be used, so he can only transfer the target to the head of the sword array.

It's all to blame for the group of crazy women at the ends of the world, didn't they just eat your piece of "Luoxia Cake"? As for chasing the master for 37,000 miles, he could only take the initiative to cover the sword heart, hey, it was really the most poisonous woman's heart. The old immortal is right.

But how do you enter the sword formation?

Forcibly untie Kenshin? No, those old things said that Kenshin can only wait for the dust.

But what are you waiting for, how long do you have to wait and haven't told the master?

Xu Jingnian didn't know that if his words were heard by other cultivators, especially sword cultivators, he would definitely laugh out loud.

Once the sword heart is covered with dust, it will only have the share of scattered power, unless there is a heaven and earth treasure to recuperate, or it will be a powerful solution to solve it, and it is definitely not so simple.

Throughout the ages, sword cultivation is the sword heart, who doesn't regard it as a treasure, for fear of an accident, save food and drink to consolidate all the good things sword heart, how can there be a big grin, in order not to let people find out that their breath directly sealed the sword heart?

This is not a fool, or a rookie who has just practiced.

But how many people who can cultivate Kenshin will be new to cultivation?

Of course Xu Jingnian didn't know this, he had been by the side of that group of old immortals since he was a child, his understanding and cognition of cultivation was naturally not comparable to ordinary people, for him, it was not a problem if the sword heart was broken, the question was whether he wanted to cultivate it again.

"Is there really no way?" Xu Jingnian was a little desperate, how to enter the Demon Sword Formation seemed to have become Xu Jingnian's heart disease now.

"No, you have to try!" Xu Jingnian shook his head, and finally made up his mind to forcibly break through into the Demon Sword Formation.

"I'm rushing!" Xu Jingnian held his breath and slammed into the Demon Sword Array.

The next moment, Xu Jingnian was ejected by the powerful enchantment around the sword array for a long time.

"Pain, pain, pain!" Xu Jingnian got up in pain and forcibly broke through this road, but it really didn't work.

At this moment, a strange cry suddenly came out in the lock demon tower.

This immediately attracted Xu Jingnian's attention. After all, in front of this demon sword array, all sounds were difficult to hear, but this strange cry came into Xu Jingnian's ears extremely clearly, which was enough to show that this matter was not simple.

Although Xu Jingnian hadn't seen the source of this sound with his own eyes, he was almost certain that this sound was definitely not made by an ordinary demon in the Lock Demon Tower, it sounded like the cry of a mouse.

Hearing this cry clearly, Xu Jingnian couldn't help but let out a soft sigh: "Strange, how can there be rats in the lock demon tower? Could it be a rat demon." But this is not right, according to what the old immortals said, the demon clan is all incarnated from beasts, and the stronger the beasts themselves, the stronger the strength of the beasts, such as tigers, snakes, bears and leopards, and other big demons, most of which are amazing. But this mere rat demon, no matter how rebellious his cultivation talent is, is limited by the weakness of his own rats after all, and it is difficult to reach too high a cultivation realm. ”

"Judging from this voice, the strength of this rat demon is not even weaker than that of the demon king imprisoned on the ninth layer, and it is very likely that it is the culprit who caused the movement of the lock demon tower. ”

Thinking of this, Xu Jingnian couldn't help but show a trace of sadness, after all, he was no different from a mortal now, even if he successfully broke through the prohibition of the Demon Sword Formation and entered the Demon Lock Tower, could he really resist this powerful existence?

"Sure enough, it's troublesome, old and immortal, if it weren't for the fact that I was trying to repay this favor for you, I wouldn't have bothered to make such a big effort. Xu Jingnian has always been afraid of trouble, but for that person, he had to do his best.

"That's it, that's the only way to do it......"
