After killing Ao Jiutian, Xiao Nan immediately returned to the previous battlefield, and saw that the army of Hannan Immortal Court and the army of Heavenly Demons were still fighting fiercely, and roared and shouted: "Yuan Qifei and Ao Jiutian have been killed, why don't you hurry up and capture the Heavenly Demon Miscellaneous Pieces?"

The voice spread far away, and the people of the entire Hannan region could hear it clearly.

When the Heavenly Demon Army heard that Yuan Qifei and Ao Jiutian had been killed, their hearts were suddenly shocked, and the movements in their hands slowed down.

However, the army of Hannan Immortal Court was ruthless, and even seized the opportunity to blast the magic weapon towards the enemy, and in an instant, there was a scream of heavenly demons, and at least tens of thousands of heavenly demons died tragically.

The commander is the soul of the army, once the commander dies, where does the army still have the heart to continue fighting? The Heavenly Demon is even more so, as soon as he heard that Ao Jiutian and Yuan Qifei were killed, the army's heart was instantly chaotic, and because of that shock, tens of thousands of Heavenly Demons died, and in just a short time, the Heavenly Demon has been defeated and retreated.

Xiao Nan rushed towards the Heavenly Demon Army at the first time, wielding the Heavenly Demon Sword and slashing everywhere in the Heavenly Demon Army, as if entering a no-man's land, hundreds of thousands of Heavenly Demons died under his Heavenly Demon Sword in the blink of an eye.

Just when the Heavenly Demon Army was in turmoil, countless human monks suddenly rushed out from an unknown place, shouting the slogan of killing the Heavenly Demon, and joined the battle circle, like a sharp sword, inserted from the back of the Heavenly Demon.

Caught off guard, tens of thousands of Heavenly Demons died inexplicably, and when they reacted, more human monks rushed out, black like ants, and blocked the retreat of those Heavenly Demons.

In front of the Hannan Immortal Court army, and behind there were countless human monks who suddenly appeared, those heavenly demons cried bitterly, knowing that the general trend had gone, they couldn't care much more, and hurriedly left the enemy in front of them and their comrades around them, and fled to both sides.

Naturally, the human monks would not let the Heavenly Demon escape so easily, and hurriedly chased after it with shouts and shouts, frantically slaughtering the fleeing Heavenly Demon soldiers.

Just a day passed, and the heavenly demons in the Hannan region were slaughtered, and the corpses were all over the field, and the blood flowed for thousands of miles.

Xiao Nan ordered someone to clean it up, and sent two flying sword messengers to inform Ling Shuiyun and Xi Qianyue, and then returned to the Hannan Immortal Court.

Three days later, the army of Hannan Immortal Court was ready to go, Xiao Nan only ordered a part of the soldiers to stay, and then led the army of Hannan Immortal Court towards the nearby Heavenly Domain.

At the same time as Xiao Nan's action, the army of Yongle Immortal Court and the army of Changkong Immortal Court had also set off, and the three major immortal courts acted together and began to sweep through the entire Upper Immortal Domain.

The six people ranked third to eighth among the twelve Great Dharma Protectors under the Heavenly Demon Emperor Throne had all died in Xiao Nan's hands, leaving the six Heavenly Demon Protectors ranked first, second, and ninth to twelfth.

The Heavenly Domain, which originally belonged to the Wind and Dust Immortal Court, also included Tianluan Heaven and Jiujia Heaven, but Xiao Nan did not find the Heavenly Demon Protector in Tianluan Tianzhong, and easily swept away the Heavenly Demon in Tianluan Heaven.

In Jiujiatian, Xiao Nan met Ji Tongchen, who was ranked tenth among the Heavenly Demon Protectors. Ji Tongchen's true appearance is a big rooster, and his cultivation is equivalent to the middle stage of a human monk, although it is not weak, but it is nothing to Xiao Nan.

Xiao Nan had already killed six Heavenly Demon Protectors in a row, and the strength of each Heavenly Demon Protector was much stronger than Ji Tongchen, and it was naturally effortless to kill Ji Tongchen, and the Heavenly Demons in the Nine Heavenly Heavens were also successfully swept away.

After subduing Tianluan Tian and Jiujiatian, Xiao Nan flew to the Deception Domain with the army of Hannan Immortal Court, and after some fighting, he killed Ji Kongshan, who guarded the Deception Domain and ranked last among the twelve protectors under the Heavenly Demon Emperor's throne, subdued the Deception Domain, and then settled down in the Deception Domain, waiting for the army of Yongle Immortal Court and the army of Changkong Immortal Court to come and converge.

About seven days passed, and the army of Yongle Immortal Court led by Han Mengyao and Xi Qianyue and the army of Changkong Immortal Court led by Ling Shuiyun, Ye Rufeng, Ye Tianyan and others successfully converged in the Heavenly Domain.

From Xi Qianyue and Ling Shuiyun's mouths, Xiao Nan learned that the third, ninth, and eleventh Heavenly Demon Protectors had also been killed, and the Heavenly Demons of the entire Immortal Realm had been completely swept away.

The second-ranked Heavenly Demon Protector died in the hands of Xi Qianyue, and it is said that the battle was earth-shattering, but when it came to Xi Qianyue's mouth, he smiled and passed by, and it seemed that it was not difficult to kill the second-ranked Heavenly Demon Protector at all.

Although Xiao Nan didn't know the specific strength of the second-ranked Heavenly Demon Protector, he still knew Xi Qianyue's strength very well, and naturally knew that Xi Qianyue had the strength to easily kill the other party.

The ninth and eleventh ranked Heavenly Demon Protectors died in the hands of Ling Shuiyun, and those two Heavenly Demon Protectors were only equivalent to the mid-stage cultivation of the Immortal Emperor, which was indeed a little stronger than the average Immortal Emperor cultivator, but it was still nothing in front of Ling Shuiyun.

At this point, the second to twelfth Heavenly Demon Protectors have all been killed, only the first Heavenly Demon Protector has not yet appeared, and the Heavenly Demon Emperor is also unknown.

It is naturally not a simple Heavenly Demon that can rank first among the Heavenly Demon Protectors, but the entire Heavenly Demon in the Upper Immortal Domain has been swept away, and the people sent to the Middle and Lower Immortal Domains have not found the Heavenly Demon Protector who ranks first.

After thinking about it for a long time, everyone could only attribute the reason to the fact that the number one Heavenly Demon Protector was responsible for staying in the Tianyao base camp, so everyone couldn't find it.

As for the Heavenly Demon Emperor, everyone knew that he had come to the Immortal Realm, but no one knew where he was, and even the entire Upper Immortal Realm had been searched, and there was still no news.

Although everyone was a little worried, they couldn't find the Heavenly Demon Emperor, and they had no way at all, so they could only attribute the reason to the fact that the Heavenly Demon Emperor had returned to the Heavenly Demon Lair.

Xiao Nan originally had the idea of attacking the Heavenly Demon Lair and letting those Heavenly Demons taste the power of the immortals, but now that the Heavenly Demons of the Immortal Realm have been purged, and the armies of the three immortal courts have converged into one place, this moment is naturally the best time to attack the Heavenly Demon Lair.

Among the people, Xiao Nan's prestige can be regarded as the highest, since Xiao Nan said that he wanted to attack the Heavenly Demon Lair, naturally no one objected, so after cleaning up, the army of the three immortal courts flew towards the direction where the Heavenly Demon Lair was located under the carrier of many spaceships.

The Heavenly Demon Lair is naturally not in the fairy world, but it is not too far from the fairy world. When the Four Great Immortal Emperors were there before, the Four Great Immortal Courts had attacked the Heavenly Demon Lair.

However, at that time, the four immortal courts were not very harmonious, even if they attacked the Heavenly Demon Lair, it was only a certain immortal court acting alone, so even if they attacked the Heavenly Demon Lair, they could not do anything to the Heavenly Demon Royal Court, at most, they would kill a few Heavenly Demons
