After a long time, Su Mo found no trace of the enemy, and the palace protective formation was not attacked again, so he returned to the Sky Palace.
"Palace Master!"
When Su Mo flew to the Thousand Earth Tower, Jin Yi, Huo Yi and others came to him one after another.
"Pay attention to precautions. If enemies appear, notify me immediately!" Su Mo ordered.
"Yes, Palace Master!" Several puppets responded.
Su Mo nodded, entered the Houtu Palace, and started practicing again.
While practicing, Su Mo did not forget to pay attention to the palace protection formation outside. If he was attacked again, he would take action immediately.
However, Su Mo was obviously over-concerned. Ten days had passed and the palace-protecting formation was not attacked again.
After that, Su Mo practiced with peace of mind and stopped worrying about it.
After entering the second level of the Martial Emperor Realm, his speed in tempering his profound strength dropped sharply again because his profound strength was too strong.
In this way, another month passed, and Su Mo's profound strength was almost tempered, and he felt that he could try to break through.
"I hope it will work!" Su Mo sighed, then entered the Void Realm Divine Map, took out all the spiritual stones and elixirs, and began to devour them with his eyes closed.
In an instant, his whole body was enveloped in rich spiritual energy.
Su Mo's cultivation was at the early stage of the second level of the Martial Emperor Realm. As he devoured the spirit stones, his cultivation began to grow rapidly.
Time passed, and after about three hours, all the spiritual energy was swallowed up, and Su Mo opened his eyes.
"Why!"
Su Mo sighed helplessly. After all the spiritual stones and elixirs were exhausted, his cultivation level could only reach the peak of the second level of the Martial Emperor Realm, let alone the third level of the Martial Emperor Realm!
"This is too much consumption!" Su Mo smiled bitterly. There were nearly 5 billion of the best spiritual stones just now, and there was also a small amount of spiritual herbs and elixirs, which was not enough.
As for the congratulatory gifts sent by Tianya Hai Pavilion, he had already given them to Guang Yi and others and assigned them as disciples.
Of course, those congratulatory gifts are of little use to him. The spiritual stones are all high-grade spiritual stones and have no real use to him.
As for the fake dragon beads given by the Jiaolong clan, he kept them for improving his physical body.
"Looks like we have to find another way!"
Su Mo looked thoughtful. There were still many spiritual stones, spiritual herbs and other resources in the Cangqiong Palace, but they were all lower-level resources and were reserved for the disciples in the palace.
If he used it, he would probably use it all at once, and then other disciples would have no resources to use!
"We have no choice but to go out!" Su Mo's eyes sparkled. This time, he went out firstly to find resources, and secondly to investigate the movements of the major forces in the world, especially the Underworld Demon Sect.
After the birth of the Cangqiong Palace, no one from the Underworld Demon Sect showed up. Su Mo didn't believe that the Underworld Demon Sect would let him continue to develop.
The last time the palace-protecting formation was attacked, there was a 90% chance that it was caused by the Underworld Demon Sect. The purpose of the test was to see the defensive power of the Cangqiong Palace's palace-protecting formation.
The defensive power of the palace-protecting formation was strong enough, and the Underworld Demon Sect was not sure of breaking through it, so he did not show up.
But if the palace-protecting formation was not strong enough, people from the Underworld Demon Sect would probably have come in long ago.
Immediately, Su Mo left the Thousand Earth Tower, found Jin Yi and other puppets, explained carefully, and left the Cangqiong Palace.
What Su Mo told him was very simple, that is, no one in the Cangqiong Palace was allowed to go out before he came back, including Sikong Yan, Jiang Fengran and others. The palace protection formation was also in operation all the time and could not relax even for a moment.
The palace-protecting formation opened a passage. Su Mo flashed and rushed out of the Cangqiong Palace. The passage was then closed.
Su Mo looked for the direction of Tianya Hai Pavilion, drew his sword, and quickly headed towards Tianya Hai Pavilion.
Above the clouds, Su Mo was traveling at lightning speed, but he only flew for half a day before he stopped.
"Hey, rat, since you're here, come out!"
Su Mo narrowed his eyes slightly and turned to look behind him. He was mentally strong and could vaguely feel that someone was following him, and he didn't know who he was.
"Hahaha!!"
As soon as Su Mo finished speaking, he suddenly remembered the maniacal laughter. The next moment, five black streams of light suddenly shot out from the thick clouds in the distance.
The five streams of light arrived at extremely fast speed and surrounded Su Mo in an instant.
Then, the stream of light stopped and transformed into five men in black robes.
The aura of these five men in black robes is extremely powerful, as vast as the sea, stirring up the wind and clouds in the nine heavens, and is unfathomable.
One of them, Su Mo was very familiar with, was Yan Tai, the great elder of the Underworld Demon Sect.
"Su Mo, your death has come!" Yan Tai shouted coldly with murderous intent on his face.
"Is this the method of your Underworld Demon Sect?" Su Mo looked disdainful. In fact, before he came out, he had also thought about whether the Underworld Demon Sect might have an ambush outside.
However, due to his confidence in his own strength, he is determined not to be afraid!
Unexpectedly, the Underworld Demon Sect actually had an ambush!
"Do you think you still have hope of escaping in the hands of me and the four palace masters?" Yan Tai sneered.
"Four palace masters?" Su Mo raised his eyebrows when he heard this and looked at the other four people.
These four people are very extraordinary, with different auras. One of them has corpse aura rising into the sky, forming a billowing smoke. He is as skinny as firewood, shaped like a mummy, with stork bones bulging high on his face. This should be the master of the Shelu Palace.
The other person had a ghostly aura about him, and his face could not be seen clearly. There seemed to be ghosts flickering on his body, with teeth and claws bared, which was very scary.
There was another person who was short in stature, but his body was extremely yin-yin. The strong yin-evil aura was extremely cold, as if it came from hell, making the space within a thousand miles around become cold.
The last person's appearance is that of a young man. His face is expressionless, and although the aura on his body is extremely weak, it is hard to tell the depth.
These four people are the masters of the four major demon palaces of Shiluo Palace, Ghost Luo Palace, Yin Luo Palace, and Yama Luo Palace. They are all super strong men at the ninth level of the Martial Emperor Realm.
Moreover, among them, the masters of Yama Luo Palace and Gui Luo Palace are at the peak of the ninth level of the Martial Emperor Realm.
Su Mo's expression became slightly more solemn. Although he was now confident that his strength was not weaker than the average ninth-level Martial King Realm warrior, and might even be two points stronger, he had to be cautious when faced with the encirclement of five people.
It seems that the Underworld Demon Sect has also made up its mind to kill him, otherwise it would not have dispatched such a lineup!
"Yan Tai, you guys who don't look like humans or ghosts want to kill me. You are really overestimating your capabilities!" Su Mo had a sarcastic look on his face. Although he was solemn in his heart, he could not say it verbally.
The momentum is weakened.
"court death!"
"act recklessly!"
The five people were furious when they heard this, and the master of Guiluo Hall took the lead. He pushed forward with his big hand, and there was a gust of wind in front of him, and a terrifying evil ghost appeared in an instant.
