The 'Gate' of Darkness is 100 meters high and 1,000 meters wide, and whenever a monster dies, the resentful spirit will fly in, and it won't be long before more monsters appear.

This is also the reason why Mu Tian wants to go in and have a look, he has seen it when he was in the Buddha Realm, and he has encountered it in the Immortal Realm later, but because the Immortal Realm has been destroyed, Mu Tian has never had a chance to go in.

At this time, there is a chance, Mu Tian will not let them destroy it easily, even if they want to destroy it, they have to go in and take a look.

The moment he rushed into the 'door' of darkness, the gravity here made Mu Tian spin uncontrollably, and countless resentful ghosts pounced, Mu Tian silently recited the scriptures in the ground, and the Buddha's light soared into the sky, directly annihilating these powerful ghosts.

After a long time, Mu Tian fell from the sky on a stone platform, and when he looked around, the gray sky was full of 'yin' and 'cloud' spirits floating, and there were more than a dozen huge stone tablets standing nearby.

There was a broken sword on the stele, Mu Tian's eyes flickered a few times, and he walked over.

The gravity space here is a little unstable, and there is a possibility of collapse at any time, and Mu Tian doesn't dare to fly around casually, so he walks over very carefully.

A few minutes later, Mu Tian walked to the bottom of the stone tablet, wiped the dust off it with his hands, and a line of illegible handwriting appeared in front of him.

After Mu Tian recognized it for a long time, he recognized a sword character, and the other words were not clear to read, or the words were ancient and could not be recognized at all.

At this time, Mu Tian noticed the sword on the stone tablet, this sword should be countless years old, and cracks appeared in the weathering, and he didn't know who left this sword here.

Mu Tian turned his head and looked around, this barren land did not have the slightest life, which also made Mu Tian suspicious, could it be that this was behind the 'door' of darkness, why couldn't a single monster be seen.

Just as Mu Tian was about to turn around, suddenly, a statue attracted attention, this statue was in an inconspicuous corner, with no facial features, only the rudimentary form of a person, but this statue gave Mu Tian a very uneasy feeling.

Mu Tian gently put his hand on the statue, but he didn't expect that cracks appeared in the statue, and finally the cracks spread out like spider webs in all directions.

Seeing that the statue was about to explode, Mu Tian took a few steps back suddenly, and the next moment, the statue finally exploded, and an old man appeared in front of him.

"Shhh ”

Mu Tian gasped, there was an old man inside.

"What are you. Mu Tian took the initiative to ask.

The old man opened his eyes, and there were stars flowing in the vicissitudes of life, and an invisible breath blew across the land, and a small whirlwind condensed behind the old man.

Mu Tian's pupils shrank, and just when he thought the old man was going to make a move, the other party spoke: "I am the guardian here." ”

"Guardian?" Mu Tian frowned, and then asked, "What is this place, what are you protecting?" ”

The old man looked at Mu Tian with mysterious eyes, and said in a calm voice: "A monster has been suppressed here, it is the origin of all monsters, and several supreme powerhouses have died because of it......"

Mu Tian asked in shock, "What the hell is it!"

The old man shook his head and didn't answer Mu Tian's words, the other party raised his hand and said indifferently: "No one can come here, and no one can leave alive." ”

"You!"

Mu Tian was shocked, and was about to make a move, when the breath of destruction fell from the sky, instantly sending Mu Tian flying countless meters away, and blood spurted out on the spot.

The next moment, the space in the sky was torn apart, and Mu Tian was grabbed out with both hands, and the 'essence' light flashed in the pupils of the old man's eyes: "Long ...... You're breaking the agreement!"
