With a "bang", the muzzle of the cannon cut by the back knife exploded directly, and it was filled with powerful energy converted from the Yuanli Crystal, causing a powerful explosion in this alley in an instant.

Although this kind of explosion is extremely explosive in an instant, it has no deterrent effect at all for Mo Zhiyu. Mo Zhiyu just took the sword back and used Yuan Force to envelop a small barrier in an instant, narrowing the scope of this explosion to a minimum, and it couldn't even blow down the walls on the left and right.

However, the escapee closest to the muzzle of the cannon was miserable, after this explosion, this person directly became a piece of black charcoal, but this person did not die, as long as the Yuan Jing was still in the Illusory Yuan Realm, he could not die, and when the explosion first started, Mo Zhiyu protected this person's Yuan Jing.

Now, he directly lifted the piece of "black charcoal" on the ground with his hand, and asked indifferently: "You shot the Yuanli cannon on the bell tower just now?" Why? ”

"Uh...... Uh......" This piece of "black charcoal" opened his mouth, he is now extremely injured, and he has no intact speech function at all, but of course Mo Zhiyu doesn't care if this person can speak or not, as long as Yuan Li is still there, he can communicate with his divine sense.

So he used the ink knife to withdraw from his body and drew a small circle on the person's forehead, so that the person did not have to speak directly, and this circle could "play" all the words in his divine consciousness.

As soon as the circle was formed, a word came out: "Lead......

But before the word was finished, this person's breath was all gone, and Mo Zhiyu could accurately feel that this person's Yuan Jing suddenly exploded on its own, as if someone had pressed a time bomb.

But Mo Zhiyu immediately caught the next Yuan Force aura. This Yuan Force aura just appeared, and it passed some to the "black charcoal" in Mo Zhiyu's hand.

Although Mo Zhiyu didn't know what strange way these people were using, it was obviously caused by the new Yuan Force aura that had appeared in this new article. Therefore, Mo Zhiyu decisively shook off the black charcoal, and one jumped up, and chased after the next Yuan Force breath.

But soon, Mo Zhiyu discovered that something was wrong, because this Yuan Force aura was actually heading towards the palace. So it was the little emperor in the palace who made such a big move just now?

This little emperor still said that he wanted to win him over during the day, and he came to make a trick at night, which is too insidious, right? It doesn't conform to the rules of the rivers and lakes at all!

However, things did not go in the direction he had envisioned. Because this Yuan Force aura actually disappeared at the moat outside the Imperial City.

Mo Zhiyu landed on a tall building outside the moat, and he frowned slightly, feeling something difficult.

Because although the entire Chang'an City already has a very powerful protective array, this most important palace has another magic array, and this magic circle is the moat that surrounds the palace.

Ordinary people can't see the true purpose of this moat, but Mo Zhiyu can see that it is from this moat, a sky-high wall of Yuan Qi surrounds the entire palace.

And this air wall not only has a protective effect, but also a purifying and shielding effect. In other words, there is a separate barrier inside the qi wall, and as long as someone enters this qi wall, all the breath of that person will be isolated.

And the guy that Mo Zhiyu was tracking just now had already entered the qi wall.

Mo Zhiyu could only judge the whereabouts of that person by the faint aura that remained outside the wall, but it was strange that the person did not go through any of the outer doors of the palace, but disappeared into a corner.

This made Mo Zhiyu think for a while, and then he suddenly woke up, could it be that there is any secret door in this river?

With an idea in his head, Mo Zhiyu immediately took action.

Although the palace was heavily guarded at night, with his stealth ability, he easily followed the guards patrolling the city across the bridge over the moat, and then directly climbed under the bridge.

Mo Zhiyu hung on the bridge and looked down, and sure enough, this moat was not just a river, there were very narrow embankments on both sides of the river, and occasionally some caves drained into this moat.

It seems that this moat is not just used as a wall, but also as a good drainage system. It's just that the trap of the drainage system design of this ancient era is like this, and the polluted water is directly discharged to the living water without any treatment, and the quality of the living water is also polluted.

Fortunately, this magic circle has a purifying effect, otherwise, this river would not have known that it stinks for hundreds of years, but he is now hanging under the bridge, very close to the river, and he can almost smell something.

Although he was very disgusted in his heart, Mo Zhiyu still quickly fell down the stone beam under the bridge to the embankment, because this was the last place where the aura of the Yuan Force was left, so the so-called secret door should be near here.

Then, Mo Zhiyu saw a hole that had been sealed by a stone slab.

Mo Zhiyu looked at the surroundings, although the hole looked like it had not been used for a long time, and there was some moss growing around it. However, there is a clear fault between the moss on the stone door and the moss on the wall, which means that the door is still being opened, but it is rarely opened.

Mo Zhiyu glanced at a piece of fresh moss that had fallen to the ground, and it was obvious that this stone door had only been opened, so that the goal was clear.

Mo Zhiyu directly pressed his hand on the stone door, ready to solve it violently, but after thinking about it, he felt that it was inappropriate. Although he can hide the explosion well, as soon as this gate is broken, it will definitely startle the snake.

So he still thought it would be better to keep a low profile, so he took his hand away again.

He just stood outside the stone gate, taking a good look at this round stone door, and it was surprising that this stone door was not opened with a magic circle, which was really rare. In his impression, only the things of the Chentian Emperor's era did not like to use Yuan Li, and preferred to use more ancient tricks.

Thinking about it this way, this stone gate is really an old antique.

But even the trick won't stump the current ink delirium, he pressed his hand again, and the subtle yuan power emanated from his palm, wrapping the entire stone door like a new vine, and then slowly stretched into it along the crack in the door.

These Yuanli vines that passed through the crack in the door were like dexterous little snakes, and they slowly explored forward, depicting the situation behind the stone door to Mo Zhiyu little by little.
