When they heard the words' we must all die ', everyone's faces changed drastically. They suddenly realized the seriousness of the situation.

The Nine Yin Soul Return Formation was a spiritual cultivation formation.

It could condense a large amount of Yin Qi in a short period of time and use it to convert corpses, causing them to undergo Corpse Transformation and finally form zombies with the ability to attack.

Originally, they had a vampire zombie.

If another group came, it would be the end of the world for them.

Qin Yu did not have time to explain to them, he suddenly rushed out and activated a high levelled talisman, directly blowing the vampire zombie that was absorbing the nine yin auras away. At the same time, he opened his mouth and imparted to the three people the the Heaven and Earth Sword Formation's chant.

The three of them understood how serious the situation was and did not dare to be the least bit careless. They listened attentively while their hearts quickly simulated the situation.

Fortunately, they were already cultivator and possessed a certain level of comprehension towards the chants of the sword formation. Otherwise, they would really be unable to pass down such a high level sword formation in a short period of time.

In the blink of an eye, Qin Yu had finished speaking the Heaven and Earth Sword Formation's chant. The three of them familiarized themselves with the Heaven and Earth Sword Formation's chant and immediately formed a triangular formation.

They began to evolve the so-called Heaven and Earth Sword Formation.

The Heaven and Earth Sword Formation was a set of sword formation s used by many people to complement each other.

The so-called universe was a profound and endless meaning.

Once used, it would form a profound sword formation.

The power of the center of the sword formation was extremely strong.

Once an ordinary person was drawn into the sword formation, they would be able to come out alive, unless they were a peerless expert in the way of the sword, or an expert in the way of the sword, or even a formation master.

Qin Yu's objective was actually very simple. He did not hope for the Heaven and Earth Sword Formation to be able to kill the vampire zombie, but at least to be able to trap it in the center of the sword formation.

This way, he would have the chance to kill the vampire zombie.

Just as they were analyzing the sword techniques, Qin Yu was using the sixth stage talisman s to attack the vampire zombie continuously, not giving it any chance to absorb the nine yin auras to strengthen himself.

This was a plan to slow down the fighting, but Qin Yu had no choice.

He had a lot of good stuff on him.

There was a chance that he could kill a vampire zombie with one move.

But he did not use it because he did not want to show too much in front of his enemies.

The more the enemy knew about him, the more dangerous his situation became.

He needed to conserve his strength and be able to catch everyone off guard.

Another thing was, if he used a level eight or nine talisman, he could directly exterminate them.

However, he would also hurt himself because of this.

Just like how Luo Chen and the rest had released their [Fourth-Ranked Explosive talisman], affecting him.

The talisman was a treasure used for close combat. If it was too powerful, it would spread to him. Without strong protection, forget about him, but his father, Luo Chen and the rest could very possibly be torn apart by the destructive energy.

"Awoo!"

The danger was getting greater and greater, and the corpses within the ancient city had already started to transform into corpses.

Suddenly, a dragon's roar rang out.

The horned dragon that had not attacked all this while suddenly turned into a thirty meter tall body, and quickly rose into the air towards the vampire zombie.

In the air, it suddenly used its divine dragon tail and directly sent the vampire zombie flying. It then followed closely behind, repeating the same action continuously, not giving the vampire zombie any opportunity to absorb the nine yin energies.

Seeing this, the pressure on Qin Yu's heart immediately lessened.

It was at this time that the horned dragon's voice sounded.

"Master Qin, quickly teach them sword formation! The corpses in the ancient city have already started to transform, so we do not have much time left.

Upon hearing its words, Qin Yu turned around without thinking, and walked up to the three of them, and began to carefully correct some of their mistakes.
