Knowing that his body was severely injured due to his momentary mistake, or that he had self-harmed to save his life, causing his body to be severely damaged, a trace of determination flashed in the eyes of the Heavenly Fire Ancestor, and then, the Heavenly Fire Ancestor no longer had the luxury of being able to repel this army of the undead, because the Heavenly Fire Ancestor himself knew that he could no longer withstand the Lich King in front of him.

As a result, the Heavenly Fire Ancestor once again spewed out a mouthful of essence blood, and at the cost of overdrawing his life, he sent out a rather powerful fire-based magic to temporarily repel the Lich King, and then took a step back and shouted loudly: "Everyone retreat immediately, immediately return to the Heavenly Fire City, activate the Heavenly Fire Altar, and summon the Fire God to descend, hoping to keep my Heavenly Fire Sect immortal!" After finishing speaking, the Heavenly Fire Ancestor directly moved, ignoring the Lich King's attack, and directly rushed towards the Thunder Roaring Sky in the rear, and at the same time began to frantically absorb the aura of heaven and earth, obviously the Heavenly Fire Ancestor was preparing to explode.

Seeing this situation, Lei Xiaotian's expression changed greatly, and he immediately drove Lei Ao to retreat as fast as possible, and at the same time ordered Xiang Ying and the other four tenth-level divine beasts to retreat with him, and all of them released the strongest defenses to protect themselves.

At the same time, Lei Xiaotian used his soul connection to order, and the other Lich King, the King of the Death Knight and the Dreaddemon King, all gave up their opponents, surrounded the Heavenly Fire Ancestor who was about to explode, and launched a fierce attack towards the Heavenly Fire Ancestor.

Just when the Heavenly Fire Ancestor activated the self-detonation and rushed towards the Thunder Roaring Heaven, all the Heavenly Fire Sect's Fighting God Law Gods and Fighting Saint Great Demon Guide level powerhouses also gave up their attacks, retreated towards the rear as fast as they could, and directly gave up the battle.

And at this time, Lei Xiaotian felt a little uneasy when he saw the Heavenly Fire Ancestor who was rushing over frantically, so he immediately ordered all the flying undead creatures to fly in front of the Heavenly Fire Ancestor, blocking the middle between himself and the Heavenly Fire Ancestor, and attacking the Heavenly Fire Ancestor.

A moment later, Lei Xiaotian had retreated to the edge of the Warcraft Forest, and then Lei Xiaotian suddenly heard a huge explosion, and before Lei Xiaotian could react, he saw a group of undead who were originally blocking in the middle, including the four Fighting God-level undead, two Lich Kings, a Death Knight, and a Dreaddemon King, all in the air, and were smashed into pieces by a strong explosion.

After breaking through the interception of a group of undead creatures, the aftermath of this explosion even rushed to the defense arranged by Xiang Ying and others, although it did not break through the magic shield arranged by Xiang Ying and others, but it still sent Lei Xiaotian, Xiang Ying and the others five tenth-level divine beasts, rushing towards the Demon Beast Forest upside down for a distance of several hundred meters.

Of course, this explosion did not spread in only one direction, and when it blew itself up, the person who blew itself up was actually dead, so where could the attack range of the explosion be controlled, so it was attacked in all directions at the same time.

The self-explosion of a peak powerhouse of the Law God, that power can really be called devastating, even the undead canopy that originally shrouded this battlefield was also washed away, and the sun shone on the battlefield again, but at this time, the millions of undead army on the ground, as well as hundreds of thousands of disciples of the Heavenly Fire Sect, have all died on the battlefield, and almost all of them have been blown to pieces, Law God, Dou Sheng, Great Demon Guide-level powerhouses, it is time to escape, and it is difficult to describe the madness of this Heavenly Fire Ancestor with madness, it can only be said to be an extreme approach.

Fortunately, the sacrifice of the Heavenly Fire Ancestor still has a certain effect, although the sacrifice of the Heavenly Fire Ancestor himself, as well as the millions of elite disciples of the Heavenly Fire Sect, but the strong people above the Heavenly Fire Sect Dou Sheng, including the leader of the Heavenly Fire Sect, Feng Tianheng, all took advantage of the fact that when the Heavenly Fire Ancestor rushed forward, the strong people in the undead army all turned into flames and disappeared on the battlefield when they all went to attack and block the Heavenly Fire Ancestor, and they didn't even stop in the city behind them, and retreated directly towards the Heavenly Fire City.

When the Heavenly Fire Ancestor blew himself up, these powerhouses of the Heavenly Fire Sect had already retreated to the central position of that city, that is to say, they were already far away from the battlefield, so they were not damaged.

When Lei Xiaotian and Xiang Ying and the other five demonic beasts stabilized their bodies, Lei Xiaotian had already felt with his soul power that the army of millions of undead that he had summoned for more than a year had been wiped out.

At the same time, Lei Xiaotian released his soul power to explore the battlefield, at this time, Lei Xiaotian found that the entire battlefield had been silent, the undead canopy released by himself had dissipated, and at the same time, the ground was full of mutilated corpses, and the millions of troops of the Heavenly Fire Sect were all buried with their own million undead army.

Subsequently, Lei Xiaotian rode Lei Ao, accompanied by Xiang Ying and other four demonic beasts, and came to the battlefield again, at this time, Lei Xiaotian found that the entire battlefield was like a netherworld hell, not only was there a river of blood, but also the bones of the corpses had been decomposed, and there were even minced meat shops all over the ground.

Seeing this situation, Lei Xiaotian's pale face showed a trace of imperceptible convulsions because of the release of the undead canopy, and then, Lei Xiaotian glanced at the battlefield on the ground, and said to Xiang Ying: "Unleash an earth-based magic on Uncle Xiang and bury all these corpses! After finishing speaking, Lei Xiaotian shook his head helplessly, and smiled slightly.

Because Lei Xiaotian suddenly thought that the last hand of the Tianhuo Ancestor looked extremely cruel, and it could be said to be unscrupulous, but after careful consideration, it was not difficult to find that the Tianhuo Ancestor's choice was correct, because if he wanted to keep the disciples of the Tianhuo Sect who had been surrounded by the army of the undead, then the Fighting Saint, the Great Demon Guide, and the Fighting God of the Tianhuo Sect, A strong person at the level of a god of law must desperately block the opponent's high-level undead, as well as the five ten-level divine beasts, but there is a huge gap in strength, and he is already at the end of the crossbow, just like that, on his side, there are only five powerhouses at the level of fighting gods and gods, and there are more than thirty powerhouses at the level of the great demon guide of the fighting saints, but the enemy has five ten-level divine beasts, as well as two lich kings, a king of death knights, A Dreadful Demon King, plus a Law God-level undead mage, these add up to ten powerhouses equivalent to the Fighting God Law God level, and the enemy also has hundreds of undead creatures equivalent to the Dou Sheng's Great Demon Guide level, such a strength compared to the people of their own Heavenly Fire Sect, they can't hold it at all.
