Outside the Penglai Ancestral Palace, Qi Tianyu stood with his hands behind his back, standing in the wind, and said sarcastically: "Penglai Xiaoer, why is your so-called Penglai Mountain Protection Array so fragile? It's just like paper paste, it will break when you poke it, it's really disappointing to me!"

Penglai Ancestor's face was complicated, surprised, ashamed, fearful, and even more ruthless, he knew that he had finally met the strongest opponent today, if he didn't use his twelve points of cultivation, I am afraid that what was waiting for him would only be ashes.

"Qi Tianyu, you have once again subverted my understanding of you, but don't be too happy, I have been Penglai for thousands of years, if you can't even suppress it in the early stage of a knot, wouldn't it be ridiculous?"

Penglai Ancestor said, a pat of the storage bag, a long knife with a black body flew out, when it first came out, it was only as long as a finger, and he took it in his hand and waved it in the wind, and it rose sharply ten zhang, on which there were countless obscure runes circulating, and the divine chain of order and rules was intertwined, as if it was connected with the heaven and earth of Penglai Secret Realm, and the blood of every Penglai monk was connected together.

When Qi Tianyu saw the Heavenly Sword, a trace of surprise flashed in his eyes, and there was also a hint of surprise, as if the navigator had discovered a new continent.

"Qi Tianyu, this Heavenly Knife has not been used for three hundred years, and in three hundred years, no one has ever used it, and now, you have become the first person in three hundred years.

This heavenly sword, is 30,000 years ago when Emperor Yu ascended from the earth when he left behind, is his warrior on the earth, a blow can kill the Yuanying monk, because of this, I don't know how many people covet it, want to take it for themselves, at least 100,000 people, because of the fight for it lost their lives, but in the end it went to the secret realm of Penglai, became the treasure of Penglai.

Today, I will use your blood to sacrifice this heavenly sword, so to speak, you enjoy the treatment that only Yuan Ying can enjoy, and you die without regrets!"

Penglai Ancestor was holding the Heavenly Knife, looking like he was holding the victory, but Qi Tianyu had a strange face, looking at the Heavenly Knife, he really didn't expect that the Heavenly Knife he left over from 30,000 years ago had always existed, and now it was in the hands of Penglai Ancestor, an opponent.

"What's the matter, Qi Tianyu, are you stupid? It's no wonder that in this world, Emperor Yu may only have this one soldier left. Who is Emperor Yu? He is the Lord of All Worlds, his soldiers, you probably haven't heard of it before, right? Now that you see him, you'd better be killed, I'll give you a good time, otherwise I will definitely make your life worse than death!"

"Penglai Xiao'er, although you have the Heavenly Sword, it is not certain that it will not listen to you, are you too happy?" Qi Tianyu said with a strange look.

"Haha, Qi Tianyu, you don't have to bother, three hundred years ago, this knife was used by my master, he used Jin Dan to cultivate, and cut off the head of a Yuan Ying with a knife, three hundred years later, this knife will also be used by me, I don't believe it, you can escape the punishment of the Heavenly Knife!" Obviously, Penglai Ancestor has great confidence in the Heavenly Knife.

"Then you can give it a try. Qi Tianyu smiled all over his face, as if he was not facing a heavenly sword, but a toy.

Penglai Ancestor was furious in his heart, and Qi Tianyu's calm and calm appearance made him always feel a little weird, and even suspected that he already had a way to deal with it.

However, the arrow was on the string and had to be sent, he waved the heavenly sword and swept towards Qi Tianyu. Normally, under this sweep, there will be countless sword lights appearing at the same time, just like the water of the Yellow River coming up from the sky, and the waves along the way are unstoppable.

However, a strange scene appeared, this knife did not have any power, not even a trace of wind stirred, it was like a child holding a branch and lightly slashing in the air, not even a flying insect could hurt.

"This is your attack, why don't you have any strength from me!" Qi Tianyu pretended to be surprised.

Penglai Ancestor was stunned, staring blankly at the Heavenly Sword in his hand, with a hundred thousand whys in his heart, as if a herd of horses was galloping by, trampling on his original full self-confidence.

"Come again!" he picked up the heavenly knife again, and slashed a hundred knives in an instant. It stands to reason that these hundred sword lights will pour on Qi Tianyu's head like the Tianhe River bursting its embankment and the boundless waterfall, but a miracle happened again, this hundred swords just looked a little amazing, but in fact they didn't have any power, and they didn't even bring up a piece of dust.

"Hiss-" Penglai Ancestor was stunned to the extreme, he couldn't believe this fact, the heavenly knife that was enough to kill Yuan Ying actually failed in front of Qi Tianyu and became the most ordinary mortal knife.

There are only two possibilities, one is that the knife maker does not have enough internal qi to urge the knife, and the other is that the knife met its owner, just like a vicious dog in the eyes of others, but in front of the master is a tame and loyal dog.

Penglai Ancestor immediately ruled out the first possibility, he had broken through to the late stage of the Jiedan, and the internal qi was enough to prompt the sword, then, there was only one possibility, that is, Qi Tianyu, who was the real master of the Heavenly Sword, that is, the prehistoric Emperor Yu, who was the lord of all worlds.

Emperor Yu, this name is so glorious, it has been circulating on the earth for 30,000 years, and countless monks have even worshiped him as a statue of a god.

No one dared to call him by his full name, they all thought that it was a great disrespect to Emperor Yu, and in the long run, few people knew what his full name was.

Because of the inheritance of thousands of years in the Penglai Secret Realm, he knew the name Qi Tianyu, and now, the ancestor of Penglai suddenly thought of this name, and his heart suddenly sighed, with intuition, he felt that Qi Tianyu was likely to be the prehistoric Emperor Yu.

"Qi-Qi Tianyu, I have a question, are you the prehistoric Emperor Yu?"

"Hehe, yes and no!" Qi Tianyu smiled mysteriously.

"Ah, I see, you must be a doppelganger of him, or his reincarnation, so you are him, but not him. "Penglai Ancestor is finally convinced that what he met today is none other than the strongest Immortal Venerable who has ever appeared on the earth, Emperor Yu!

"Emperor Yu is above, please bow to Ao Xiong!" Penglai Ancestor is named Ao Xiong, he knows that even if it is just the doppelganger or reincarnation of Emperor Yu, it is not something he can afford to provoke, after all, this doppelganger or reincarnation is rooted in the real Emperor Yu, and he has all the Dao methods of Emperor Yu, so he naturally stands at the peak of cultivation.

At this moment, a sudden change occurred, under the feet of Penglai Ancestor, suddenly a long sword poured out from the ground, Penglai Ancestor didn't understand what was going on, his body was pierced by a sword from bottom to top, and he died immediately.
