Time passed by quickly, and before anyone knew it, night fell. The vast darkness of the night covered the entirety of South Heaven City.

Inside the hall of the Symbol Master Guild, a black shadow silently snuck in. It directly flew past the lobby and arrived at the back. When it turned a corner, the figure stopped.

Under the dim moonlight, a handsome and resolute face was revealed. This was Ling Yan, who was about to investigate everything at night.

Ling Yan did not turn his head to go out and check. His blood energy slightly rotated as his sharp spiritual sense instantly dispersed in all directions. Very soon, two figures appeared at the end of the corridor within Ling Yan's perception range.

As expected, it was twenty-four hours a day. Ling Yan's black eyes narrowed slightly.

However, when humans slacked, even the strongest martial artists couldn't maintain 100% of their spiritual energy 24 hours a day, not to mention the two martial artists who were only at the 4th level of the Mortal Core realm.

If he forced his way in, in order not to ruin his plans for the future, the only thing he could do was to kill the two guards.

However, this would easily raise Fu Zhu's vigilance and cause some trouble for what he was about to do.

Therefore, he could only sneak past the two Mortal Core warriors without anyone noticing. The safest method was to knock them out in an instant, and not cause them to make any noise.

Because Ling Yan didn't know whether Fu Zhu was nearby or not, if he was, it would cause too much noise and alert Fu Zhu. Even if Fu Zhu's strength was slightly lower than that of an ordinary fifth level Mortal Core warrior, he would still be in great danger!

Although Ling Yan was confident that he could knock out two ordinary Fourth Stage Mastery Stage martial artists in an instant, it was inevitable that his appearance would be revealed. Fortunately, he still had other methods.

The corner of Ling Yan's mouth slightly curled up as he stretched out his right hand. With a slight thought, traces of yellow lightning twined around Ling Yan's right hand like tiny electric snakes.

The power of fire was at the middle stage of the Xuan grade. Even a martial artist at the fifth stage of the mortal realm would be injured and affected by it, let alone a fourth stage mortal.

With the strength of the power of thunder that Ling Yan currently grasped, it was easy for him to paralyze two Fourth Stage mortal martial artists in an instant, unless they were prepared and used their true essence to protect their entire bodies.

However, looking at how absent-minded the two of them were, it was likely that they did not notice Ling Yan's arrival.

Ling Yan's complexion was indifferent. He flicked his finger and two tiny bolts of yellow thunder instantly sunk into the ground. In the blink of an eye, they arrived at the end of the passage. They directly drilled into the bodies of the two black-clothed martial artists like poisonous snakes.

The two black-clothed martial artists immediately gave a stuffy cough. Their bodies stiffened and their eyelids rolled up, about to fall to the ground.

Ling Yan's black eyes flashed, and he activated Thunder Flash. His figure flashed like lightning and arrived beside the two black-clothed martial artists, gently stopping them from fainting. He then placed them on the ground, his movements as smooth as flowing water, silent and noiseless.

Done!

Ling Yan stood still for a few seconds. After the surroundings did not move, he let out a sigh of relief.

Raising his head, he saw that at the end of the corner, there was a room with a door that was clearly thicker than the other rooms. The door was made of an unknown material, and even in the dark night, there was still a glimmer of black light.

On top of this layer of black light, there seemed to be a layer of faint blue light.

Ling Yan thought to himself, this should be the sound barrier that Fu Zhu had set up. On the left side of the door, about five feet from the ground, there was a square frame that was slightly larger than the palm of his hand.

Without giving it much thought, Ling Yan slowly walked over …
