In a broad hall on the main peak, Great Heaven Peak, a huge number of disciples hustled.
The hall was named the Great Yin-Yang Palace as it contained the entrances to the Planes.
Su Mo, Tian Chen, and the other two walked into the Great Yin-Yang Palace after they arrived at Great Heaven Peak.
Su Mo saw dozens of doors in white splendor, and disciples were entering the doors one after another.
"The Celestialspirit Sect possesses dozens of Planes. They are basically pulled out directly from the voids by our ancestors!" Yun Fei introduced to Su Mo.
Su Mo was impressed by the unimaginably powerful method of directly pulling out a vast Plane from the void.
"These Planes are not huge in general. The smallest one is about 500 square kilometers, while the largest, the Horned-demon Territory, is about 500,000 square kilometers. The Horned-demon Territory is also the most ideal place for training, and most of the disciples choose it."
"There is a fixed spell at each entrance, and only outer disciples under the True Darkness Realm are allowed. Inner Disciples can't enter at all."
Su Mo nodded. Among the dozens of entrances, only the tallest one in the middle was the busiest as it had numerous disciples entering and exiting in a continuous stream.
Most of the disciples who entered the Horned-demon Territory were at the Enlightenment Realm, with a few disciples at the True Spirit Realm.
"Junior Brothers, let's go!" Feng Shaoyu said and flashed into the Horned-demon Territory.
The other three quickly followed him.
After they entered, a black-clothed young man's eyes paused at the entrance for a while, and he left the hall to head toward the Holy Sky Peak.
Not long after, the young man in black met a brown-robed elder in one of the palaces on Holy Sky Peak.
"First Elder, Su Mo and three other Towering Sky Peak disciples entered the Horned-demon Territory!" He reported to the elder respectfully.
"Is that so?"
The elder's eyes glittered. He paused for a while and asked, "Is Hua Suiyu with them?"
The elder did not mention Jun Wuxi because Jun Wuxi was at the True Darkness Realm and could not enter.
"First Elder, Hua Suiyu is not with them. There's only Su Mo, Tian Chen, Yun Fei, and Feng Shaoyu!"
"I got it! Off you go!" The elder nodded slightly and waved off the young man in black.
The elder looked over at Towering Sky Peak with murderous eyes.
"Huangfu Qing, your disciples kill mine at will. As the First Elder of Holy Sky Peak, how can I remain indifferent and do nothing?"
"This time, I will cause some serious loss to your peak! Haha!" The cold-blooded laughing echoed in the hall.
...
After entering the entrance, Su Mo felt like the sky and earth were spinning around. The feeling disappeared seconds later as he landed on the ground.
He found himself in a tiny city surrounded by tall walls. His spiritual consciousness swept here, and he found out this place was only 2,500 square meters large and it was better to call it a castle than a city.
Surprisingly, there were businesses such as shops, taverns, and restaurants.
The sky in this Plane was extremely gloomy with jet-black clouds. The air was depressing as it had a cruel and fierce atmosphere.
Su Mo knew that the air was Demonic Qi. Dense Demonic Qi filled this Plane.
At this moment, Su Mo was on the square in the center of the castle, and his Senior Brothers also arrived next to him.
There were more than one thousand disciples at the square. Some just arrived, some were sitting cross-legged and cultivating, and some were stained with blood or injured, healing themselves.
Above the square hung a huge door. Obviously, it was both the entrance and the exit of this Plane.
"Tenth Senior Brother, is this the Horned-demon Territory?" Su Mo asked Tian Chen.
Tian Chen nodded and said, "Correct, and this castle is called Demon-controlling Fort. This is our only stronghold in Horned-demon Territory. You can find a huge number of horned demons outside the castle!"
Su Mo nodded and asked, "How is the strength of the horned demons?"
Tian Cheng said, "The strongest ones are at the True Darkness Realm, yet only Lv 1 True Darkness Realm. They are barely seen in this Plane. Once we spot horned demons in the higher levels, Celestialspirit Sect elders will kill them personally!"
Su Mo nodded again. The elders must keep balance in Horned-demon Territory since it was a Plane for training. The strength of the horned demons could not be too weak or too strong otherwise the training would be ineffective!
"Will the demons attack this fort?" Su Mo asked. Since the demons were not weaker than Celestialspirit Sect disciples, they would not ignore Demon-controlling Fort.
"Of course!"
Yun Fei nodded and said, "Ten years ago, they occupied the fort and forced our disciples out of the Plane. After that, all of the top-notch outer geniuses from the nine peaks joined forces and managed to take Demon-controlling Fort back!"
"Without the elders?" Su Mo was surprised because he thought it impossible for the demons to occupy the fort if the elders were garrisoned there.
"The elders won't intervene unless a Lv 2 True Darkness Realm horned demon appears!"
Su Mo was upset about the elders' loose attitude toward the Plane, but he knew that this could temper the will and strength of Outer Disciple.
Besides, the horned demon with the highest cultivation was only at Lv 1 True Darkness Realm, which was not too tough for hundreds of thousands of Outer Disciples. Many strong talents had cross-level combat strength, so it was possible for a Lv 9 Enlightenment Realm disciple to kill a Lv 1 True Darkness Realm horned demon.
"Let's go to the tavern and learn some news about this Plane!" Feng Shaoyu said and led the crew to the nearby tavern.
Feng Shaoyu had the highest cultivation level among the four, so he took the responsibility of taking care of the other three. He did not walk out the fort rashly because Horned-demon Territory was the most dangerous Plane among the others.
Thousands of disciples were killed in this Plane.
