By the time Iron Red Flame was twenty-one years old, the number of Gui Eclipse demons was already very small, and the few remaining Gui Eclipse demons had all disappeared after fleeing in the last battle of the year.

Tie Hongyan only met the Demon King for the first time in the last battle of the year, and it turned out that the Demon King had been secretly controlling many Gui Erosion Demons in the past.

In those years, the Demon King controlled the Gui Erosion Demon on the one hand, and on the other hand, he was still practicing new demon arts. During the cultivation of that new kind of demon art, if the demon king appears during the day, he will naturally absorb the energy of the sun, and if he appears at night, he will naturally absorb the energy of the starlight, but whether it is the energy of the sun or the energy of the starlight, it will have a destructive effect on the new demon art he cultivates, if he appears directly under the sun or starlight without precautions, the part of the new demon art he practiced before will be completely wasted.

When he appeared on the battlefield, he was surrounded by a black demonic aura, which was used to prevent him from absorbing the energy of the sun and starlight.

Letting this black demonic aura permeate him would consume the demonic arts he had cultivated before to a certain extent, but in order to ensure that the new demonic techniques he cultivated were not completely abolished, he had to choose to consume the demonic techniques he had cultivated before to a certain extent.

For the Demon King, who has been cultivating new demon arts, not appearing under the sunlight and stars is the most beneficial for him.

In the last battle of the year, the Demon King had to appear in order to cast a demon spell on the spot to let the remaining part of the Gui Eclipse Demons escape, otherwise the only remaining Gui Eclipse demons on the battlefield would be wiped out.

Once all those Gui Eclipse Demons are destroyed, the Demon King's own lifespan will quickly become shorter. It's not so much that he's finally showing up to help those Turtle Demons escape, it's more that he's just saving himself.

After the remaining Gui Eclipse demons all fled under the cover of the demon king's demon magic, only the demon king was left on the battlefield.

Tie Hongyan hoped to eliminate the Demon King to get rid of the trouble, but due to his limited skills, he only seriously injured the Demon King, and failed to kill him on the spot.

If the demon king is attached to the human body like those Gui Eclipse, then the demon body will immediately break away from the human body after he is hit so hard, but the demon king is different from those Gui Eclipse demons, he does not need to be specially attached to people, his humanoid body is the demon body.

He rode on horseback without causing the horse to neigh wildly, and he did not die from a metal weapon as soon as he touched it.

His demon body was not as easy to perish as those Gui Erosion Demons, and if the people who attacked him did not have great skill, it would be extremely difficult to even severely damage him.

Iron Red Flame used the Phantom Spear Technique to exert great power to inflict a heavy blow on him. The seriously injured Demon King knew that he was injured by the power of the Phantom Silkworm Marksmanship, and smiled fiercely on the battlefield: "Tianfeng Yang's martial arts...... Hahaha! Tianfeng Yang, Tianfeng Yang! Your martial arts are really amazing! It's amazing! You've been dead for hundreds of years, and your martial arts can still seriously injure me! You're going to be my enemy when you're really dead! However, no matter how powerful you are, you will die! I'm alive, you're dead! Dead! Aha......ha Do you think I can't beat you? I tell you, the whole world is mine! It's all mine! It's a pity, you just died early, you can't see it, you can't see it! The sound was so loud that it seemed to shake the earth.

Speaking of this, the demon king who was glaring at the iron red flame suddenly felt that the person who seriously injured him with the phantom spearmanship was Tianfeng Yang.

He suddenly used his remaining strength to shoot an arrow made of black qi towards the Iron Red Flame!
