A look of surprise flashed in the eyes of the old demon of Black Mountain, and he urged the Seven Kills Monument again, and the seven blood-colored killing words flew out, suddenly turning into a blood-colored sword qi and attacking the Seven Kills.

The eyes of the Seven Kills suddenly changed, and they instantly fell into a boundless sea of blood, and the mighty blood-colored sword qi came overwhelmingly. He was so nervous that he only felt that in the next moment, he would be strangled by the sword qi. At this time, the Human Emperor Sword in his hand suddenly bloomed with dazzling golden light, dispersing the blood-colored killing intent, and immediately, a dragon roar sounded, and a golden divine dragon transformed by sword qi defeated the blood-colored sword qi, and the castration was unabated, penetrating the body of the old demon of Black Mountain.

The eyes of the old demon of Black Mountain instantly lost their divine light and fell from above the clouds. Although he was an immortal demon body, this human emperor sword qi directly strangled his Yuan Shen will!

In an instant, the Seven Killings Monument turned into a black streamer and quickly disappeared.

Beside him, the faces of the many demon kings on the side of the Seven Killing Demon Palace changed instantly, and they never expected that the power of the Human Emperor Sword would be so powerful, and they directly killed the old demon of Black Mountain in seconds. Therefore, they have used their methods to escape to the northern desert or the eastern sea. Until the moment of life and death, no earth fairy demon king is willing to surrender easily.

And the demon kings on the side of the Great Chu Emperor Dynasty instantly flashed green light and killed those demon kings who fled. At this time, they are no longer strong enemies, but living feats. As long as there is enough meritorious service, the exercises, supernatural powers, and Dao Yun perceptions can all be exchanged. Especially those demon kings who are on the verge of breaking through, they especially want to use the hostile demon king's primordial gods and demon bodies to exchange some Dao Yun insights or cultivation resources of the corresponding realm to the Human Emperor Palace, so as to break through their cultivation.

And the demon army below has also fought each other, but the situation is one-sided, the demon army of the Seven Killing Demon Palace knows that it will be defeated, and has no intention of fighting, so it quickly collapsed and surrendered one after another.

As for the more than 20 earth immortal demon kings who took the lead in escaping, they did not escape far, they were blocked by the red snake, the white eagle and more than ten demon kings, although it was only delayed for a moment, but the wild bull king, the black bear spirit, and the blue tide had already caught up, and they fought all the way, and more than ten people died, and the other more than ten demon kings surrendered one after another.

At this point, the war has come to an end, although many demon handsomes and demon generals have become fish that have slipped through the net, but it does not affect the overall situation. Seven killings and breaking the army ruled the Shura Blood Guard, and the Barbarian Bull King, Black Bear Spirit, and Lan Xi led the demon army to completely pacify many mountain ranges in the northeast such as the Changbai Mountains and the Great Xianbei Mountains.

With the pacification of the north, the railways in these areas can be unimpeded, and there is a demon army to supervise and escort them, so there is no need to worry about robbers. In addition, during this time, Ling Feng has also re-upgraded the spiritual power train technology, and the roof of the car has added a spirit gathering formation, which can absorb the power of the sun, moon and stars, and greatly reduce energy consumption. At this time, the mode of transportation of the spiritual train will quickly replace the traditional methods such as horse-drawn carriages. In addition, Ling Feng was already researching the Flying Boat, and he would be able to obtain the Cultivator's Sword's way of flying.

And after this battle, the invincible prestige of the Human Emperor Sword has also spread, and it has become a supreme holy weapon in the hearts of the human race.

This is also Ling Feng's purpose, he used the Human Emperor Sword to pacify the demons of the mountains, condense people's hearts and beliefs, and match the humane spirit, that is, to sublimate it into a humane holy weapon similar to Xuanyuan Sword and Xia Yu Jiuding.

However, if you want to practice the human Dao holy weapon, there are also difficulties, if the Human Emperor Sword wants to be successfully sublimated, it cannot be defeated, once defeated, it will be wasted!

The next day, Seven Kills, Broken Army, Greedy Wolf, Wild Bull King, Black Bear Spirit, and Lan Xi led the army back to the Human Emperor Palace to resume their lives.

Ling Feng once again canonized some demon kings as the head of each mountain, and opened the exchange list of the human emperor's palace, so that those demon kings could consume their merits and exchange what they needed.

If you want to recover the hearts of these demon kings, you must beat a stick and give a sweet date. Many of the top exercises, magic weapons, supernatural powers, and various Dao Yun perceptions in the exchange list are the sweet jujubes.

......

At this time, Minshan, Snow Treasure Top, Demon Cave Mansion.

All the demon kings gathered, but they were not in the mood to enjoy the song and dance, but their faces were solemn.

At this time, the White Ape King of Motianling looked at the Minshan Demon Saint and said, "Big brother, I believe you have also heard that the Terran army has swept away dozens of demon kings in the north, and even the fierce and powerful old demon of Black Mountain has been killed by the human emperor's sword. If we don't act, it's too late!"

Next to him, the demon kings of the peaks of Minshan Mountain also said: "Yes, big brother, if you don't act, you will be slaughtered by others!"

The Minshan Demon Saint hesitated for a moment, and then said with a firm expression: "Okay, split the Turtle Mountain and rescue the Demon God Wuzhiqi!"

The White Ape King suddenly looked overjoyed, and said: "Big brother, I also contacted the three demons of Minjiang and many demon kings such as Daba Mountain, Wuling Mountain, Wuyi Mountain, etc., there are hundreds of demon kings in total, and they will definitely be able to open the Dayu seal and rescue Wuzhiqi!"

The killing intent of the White Ape King was a little stronger in the heart of the Minshan Demon Sage, but he remained silent and said with a smile: "Brother Xian has done a good job, since this is the case, we will go to Turtle Mountain together, break the seal of Dayu, and rescue Wuzhiqi!"

A few days later, at the foot of Huaiyin Turtle Mountain, on the bank of the Huai River, hundreds of earth fairy and demon kings gathered.

Qingniu Wang, one of the three demons of Minjiang, said: "I heard that Wuzhi Qi was locked in water by Dayu with iron, but the chain was made of Nine Heavenly Divine Iron, which was extremely strong and contained divine power, and it had to use an extremely sharp immortal weapon to cut off the chain!"

At this time, the White Ape King said, "I contacted a fellow Daoist, he has a divine weapon that can cut off the chain of divine iron!"

After he finished speaking, a black gas suddenly burst out of the water and turned into a black-robed man.

At this time, a demon king's face suddenly sank, and he said, "Heavenly Demon Sect Xuantian Demon Lord!"

When the other demon kings heard this, their faces suddenly sank. You must know that the Xuantian Demon Lord is a peerless powerhouse of the Earth Immortal Triple, except for a few Earth Immortal Three Demon Kings such as the Minshan Demon Saint and the Qingjiao King, the head of the Minjiang Three Demons, no one can match it! Moreover, the Demon Kings are plotting the major affairs of the Demon Clan, but the Xuantian Demon Lord is a human race, at this time, the White Ape King contacted the Xuantian Demon Monarch, could it be a deliberate leak?

"You don't have to worry, the Human Emperor is a humane and an enemy of my Demon Dao, so this time I'm here to help you!"

At this time, the Xuantian Demon Monarch said with a smile, and after he finished speaking, a long black knife appeared in his hand, the blade was jet-black and shiny, faintly exuding an extremely cold knife aura.

"This knife is called the Heavenly Demon Knife, it is a demon soldier refined by the Demon Lord Bo Xun who came to the world, it is a supreme demon soldier, as long as you urge this knife with all your strength, you can cut off the chain of divine iron!"

Immediately, the demon kings discussed it and felt that the Xuantian Demon Lord couldn't play any tricks, so they agreed.

As a result, hundreds of earth immortal-level demon kings such as the Minshan Demon Saint and the Qingjiao King and the Xuantian Demon Lord jointly condensed mana and poured it into the Heavenly Demon Knife. And the Heavenly Demon Knife is like a black hole, constantly absorbing the demonic power of the demon kings.

A quarter of an hour later, the Heavenly Demon Sword suddenly bloomed with jet-black blades, then turned into a black sword light and slashed into the water.

At this time, at the bottom of the Huai Shui, a white-haired water ape with a height of a few feet was locked at the bottom of the water by black chains, unable to move.

Suddenly, a jet-black sword light burst through the water, slashing at it, slashing at a chain that bound Ahuizotl's arm.

With a bang, fine cracks appeared in the black chain, although it was not broken, but it was almost there.
