Zhen Yuanzi saw that Chiyou agreed, so he explained.

Zhen Yuanzi is in charge of the Book of the Earth, which is the best innate spiritual treasure, which is transformed by the earth's fetal clothes, so Zhen Yuanzi also has the responsibility of controlling the world's ten thousand veins.

Just before, Zhen Yuanzi used the power of the Book of the Ground to travel through the desolate landlines, and he found some anomalies in the Western Lands.

After a closer inspection, the Eastern Princes found that an evil dragon had formed in the leyline!

This evil dragon was bred from the broken western leylines, and its strength was very strong, Zhen Yuanzi and Hongyun Ancestor had gone there in person, but they did not take each other, but were restrained everywhere.

Now the elixir refined by the Eastern Princes is precisely for this evil dragon, and it is called the Dragon Descending Divine Pill.

"At the beginning, the Demon Ancestor Rahu and Dao Ancestor Hongjun fought in the west, resulting in the destruction of the leylines, although we collected a part of the leylines, but most of them were still destroyed, I didn't expect that now this evil dragon was bred again, if it is not stopped, it will continue to devour the leylines, and it will be a disaster in the future!"

Zhen Yuanzi told the story eloquently, telling the causes and consequences together, and as a participant in it, Chi You was naturally clear about these things.

At the beginning, countless leylines were destroyed, and there was no time to rescue, and at that time, Chi You's strength was low, but he didn't have the means to reach the sky like now.

This matter is related to the Demon Ancestor Rahu, and Chiyou was also involved in it back then, so he agreed after thinking about it briefly.

Eliminating this evil dragon will inevitably help Rahu eliminate some of his karma.

Demon Ancestor Luo Hu rescued Chiyou twice, Chiyou had nothing to repay, but he always wanted to repay the other party in his heart, and now that the opportunity has come, Chiyou will naturally not refuse.

"That evil dragon has mastered the law of earth, and its strength is equivalent to the quasi-saint realm, when the time comes, let's bring him out, and we must trap and kill it in one fell swoop!"

Zhen Yuanzi was full of confidence at this time, with the addition of Chi You, a quasi-saint, and the dragon descending pill that Zhen Yuanzi had refined, it was enough to capture and kill the evil dragon.

Chiyou and they discussed, and then left Wuzhuang Guan and flew to the west together.

"Zhenyuanzi Daoyou, why do you still have seventy-two disciples with you?" Chi You saw the disciples following him, and he was very puzzled.

These seventy-two disciples are all protégés of Zhen Yuanzi, they are all strong, and the worst is also the cultivation of Da Luo Jin Immortal, and they are praised by later generations as seventy-two high disciples.

Seventy-two Great Luo Golden Immortals, this is also an extremely powerful force in the desolate world.

The hidden strength in the Wuzhuang View is really terrifying, no wonder Zhen Yuanzi can be called the ancestor of the earth immortals in the future!

Hongyun smiled at this time: "Brother Chiyou doesn't know, Brother Zhenyuanzi Dao has recently researched a powerful formation, which is jointly performed by seventy-two Great Luo Golden Immortals, and it is very powerful. Last time, we failed to make a contribution, but now for the sake of insurance, Brother Zhenyuanzi has only brought seventy-two high-ranking disciples!".

Chi You nodded, Zhen Yuanzi likes to plan and move, he is steady and old-fashioned, which is indeed very in line with Zhen Yuanzi's style.

A group of them came with auspicious clouds and soon arrived in the barren land of the West.

Chiyou has not been to the West for a long time, and at this time, there are yellow sand lakes everywhere, and there is a vast sea of sand for thousands of miles, and there is no life at all.

Since the Great War in the West, the situation here has been getting worse and worse, a large number of gaps in time and space cannot be bridged, and the already broken spiritual veins have passed more rapidly, which has made the situation in the West worse and worse.

"This is the place!" Zhen Yuanzi Daxian landed on a hill with Chi You and them, this is a dead and silent bald mountain, surrounded by desolation, like a sponge, completely drained of water.

"Array!" Zhen Yuanzi gave an order, and the seventy-two high-ranking disciples occupied their respective positions, and their whole bodies were full of evil spirits, and the large array was one and the power was unparalleled.

Earthshattering the Heavenly Array!

Seventy-two Great Luo Jin Immortals, they arranged a large array in an instant, and their power was naturally extraordinary.

At this time, the evil dragon obviously sensed the arrival of Zhen Yuanzi, and the previous war had already made the evil dragon remember the breath of Zhen Yuanzi.

As soon as the large array was laid down, the surrounding mountains suddenly shook.

Countless earth and rocks collapsed, there was a scene of earthquakes on the earth, and the entire barren mountain was completely turned over, and then a bottomless giant abyss was formed.

"Roar!"

The dragon roared and vibrated in the sky, and an earthy yellow dragon the size of 10,000 zhang rushed angrily.

"Boom!"

The earth dragon rose into the sky, overturning the infinite earth and rocks, and the huge clods of earth were carried into the sky by the dragon, and then smashed violently.

The infinite evil qi in the Earth Shattering Heaven Array rose, and it turned into swords and axes, and slashed at the air, shattering all the earth and stones that smashed into Chi You.

The seventy-two Great Luo Golden Immortals arranged the Earth Shattering Heaven Array not to passively defend, at this time, they each flew backwards, and instantly expanded the formation by more than 10,000 times, trapping this earth dragon in the big array in one fell swoop.

The evil qi stirred up the sky, so that this earth dragon couldn't distinguish between up and down, left and right, and couldn't see east, west, north and south.

"Everyone, strike together!" Zhen Yuanzi looked at Chi You and commanded directly.

The four of them were quasi-saint powerhouses, which were enough to shock and kill the earth dragon.

Chi You looked carefully at this time, this earth dragon has nine claws, a dragon head, shrimp whiskers, a snake body, a unicorn tail, the whole body is the color of earthy yellow, the scale armor is heavy, and the dragon claws are sharp.

Nine claws, it's already the realm!

Zhen Yuanzi held the book from the ground, Hongyun took out the scattered red gourd, Mu Lingzi made a divine sword, Chiyou wielded the magic knife, and they killed from all directions.

For a time, the law of earth, the law of wood, the law of war, and the law of wind and clouds all attacked the earth dragon.

"Boom!"

The earth dragon roared, its figure swinging, like a huge steel whip, pumping into the air.

The power of the Four Laws was blocked by the earth dragon, and the scale armor of his whole body fell off one after another, but there was still a piece of earth and yellow within the scale armor, as if there was no flesh and blood at all.

Without waiting for Zhen Yuanzi and them to attack, the earth dragon had already roared, and the infinite earth essence gathered again, instantly allowing the earth dragon's injuries to recover, as if they were not injured at all.

The law of the earth is incomparably thick and well observed.

The earth dragon recovered as before, as long as the aura of the earth here was endless, he could return to his peak state at any time.

This is the power of the law of the earth, and cultivating to the depths is almost equal to the immortal body.

"Only by completely obliterating him with an all-out blow, so that the earth dragon has no chance to repair, can he be completely killed!"

Chi You saw the power of this divine dragon, and it was no wonder that Zhen Yuanzi couldn't kill him before.

Zhen Yuanzi's defense is unmatched, but when it comes to lethality, he is indeed a little worse.

And Hongyun is good at retreat techniques and formations, Mu Lingzi is the best at cultivation and recovery, none of the three of them is majoring in laws such as killing battles, so it is indeed very difficult to kill each other with one blow.

However, Chiyou is very confident in slaying the earth dragon.

"Entering the quasi-saint realm, my divine sword nine turns have already been able to slash the sixth blow, and I haven't had a chance to see the strength yet!" Chi You smiled and stepped forward with his knife.
