No matter how powerful the heavy puppet is, it still has two key points: the heart and head, so the Demon Emperor is certainly clear about it.

Human beings have another great help to go offline.

"Just force the demon emperor to the middle of the formation, it can be activated, and use the formation to absorb all the energy of Cangwu's heart!" The saint knew that every minute and every second were precious at this moment, "There is not much time left for us."

"Dutian Reversal Formation?" Qiansui frowned, "Dutian Formation is the magic of Qianhong Villa to transport guests' souls into another world, so the reversal Formation is..."

She has accepted Mrs. Qianhong’s lifelong knowledge and of course she knows the secrets of Qianhong Villa.

This is one of the most important secrets.

"Yes, as long as you go back to this formation, you can return to Qianhong Villa from another world." The saint said very clearly, "You enter the world privately and are not on the return list. If you want to go back, you can only open the door yourself."

Yan Sanlang and Qiansui looked at each other.

The saint continued: "The operation of the formation kills two birds with one stone, which not only destroys the demon emperor, but also helps Asura return to Qianhong Villa. Yan Shichu, this is our only way to live!"

Qiansui saw the eagerness in love man's eyes, and knew that he had already moved, he couldn't help but say: "Yan Xiaosan--"

Yan Sanlang waved his hand, interrupting her text, and only said to the saint: "Where is the formation? It's not enough to draw it now."

The three of them talked frequently, but they were all talking quickly, and only twenty breaths had passed. However, the drawing formation was a meticulous job. The Dutian formation, which could attract tens of thousands of souls, was extremely complicated. Even Mrs. Qianhong had to concentrate on drawing for more than ten hours, let alone this retrograde formation.

Tan Xuan is already in danger, so it is definitely too late to paint it now.

While he was talking, Tan Xuan avoided the attack of the Demon Emperor in the distance. The latter's attack was incompetent, and Tan Xuan no longer dared to take it head-on. But he flew away, and the inner city wall behind him was exposed to the enemy's vision.

The Demon Emperor punched the city wall, and even Yan Sanlang was so far away that he felt the ground tremble.

The wall swayed, and the soldiers and civilians above fled around.

The Demon Emperor punched like the wind, attacking seven times within one breath, all hitting the same place.

Its fist also contains the power of lightning, and no matter how thick the wall is, it cannot bear it.

With a "boom", the wall collapsed.

The inner city gate finally made the same mistake as the outer gate of the east city.

The soft core of the oasis is now exposed in the vision of the demon army.

The civilians screamed, and the practitioners retreated in panic, mixed with the shouts of generals.

The chaos has begun.

"There is a ready-made one." The saint withdrew his gaze and pointed at Tan Xuan. "He has worked day and night for the past two days and brought the drawn formation with him. The key to the activation is with me, and I originally wanted to meet him."

Qiansui curled his lips and was secretly disappointed.

She wanted to wait for the saint to tell him a way, and she would kill him with one spear, and she would never suffer any future troubles.

However, this guy is indeed cunning and never forgets to leave a way out for himself. As long as he is useful, the two of them cannot kill him for the time being.

The fighter is urgent, and Yan Sanlang will not spend his time grabbing his "key".

The most time-saving way is to let the saint activate the formation by himself.

The three of them hid behind the broken wall, but at this time the demon army rushed around, and several monsters finally found them and rushed up with big mouths.

"seek death!"

The two thousand-shou whips tie them up and raised their energy and shouted loudly to Tan Xuan: "Put out the Great Array of Defiance!"

The sound was clear and cool, but it shook like thunder, echoing above the entire battlefield.

Of course, Tan Xuan heard it. He happened to be repelled more than 20 feet away to the edge of the wall. While spitting out blood stasis, he took out something and inserted it heavily on the ground!

It was a small brass door, not as big as Tan Xuan's slap.

"long!"

Tan Xuan angrily yelled two words "long".

With each yell, the brass door will be enlarged ten times.

By the end of the two sounds, the gate was as high as thirteen feet (forty meters)!

This height is even higher than the height of a stone mantis spider. It can just block the holes in the city wall and prevent more monsters from rushing into the inner city.

Tan Xuan also stepped on the top of the brass door obediently, and then stepped onto the wall.

The object came out of the air, and the Demon Emperor was also surprised and stopped subconsciously.

He knew that humans were cunning and would struggle to the death until the end.

What trouble did you do this time?

Qiansui was also observing. She inherited the knowledge of Mrs. Qianhong and was very clear that to solidify this formation into a formation, the most important and rarest material is Jingxuan Iron.

This object gives the array the characteristics that it can be large or small.

It happened that several magical powers outside the city hit the brass door and disappeared. It seemed that Tan Xuanzao did not cut corners.

At a glance, the formation is engraved, as if there is no error.

In the middle of the gate, there is indeed a huge depression, commonly known as the array eye.

It is this position. If there is a golden scale, you must put it in. If not, then Cangwuxin is the best choice.

Yan Sanlang stretched out his hand and pointed: "That is the spirit stone we risked our lives to regain our lives."

The brass door's array was red and purple. When you looked closely, the center was a base made of natural and complete spiritual stone grinding.

I think so, if you want the Dutian Reversal Array to perform the best effect, you naturally need to use the best spirit stone.

The last time Yan Sanlang and Liemu went out of the city with the army, they went to the Xishan mining area to grab the spirit stones. The largest and most beautiful piece of them were never seen, and it turned out that they were used by Tan Xuan.

He really invested a lot.

The brass door appeared in the world, causing the inner city wall to shine yellow. It happened to hit the door with a thick thunder blowing from the sky.

As a result, the gate was as bright as new as new, without even a trace of charred black. Instead, blue and white lightning spread from the gate to the inner city walls.

The human standing on the wall was fine. The monster climbing up the wall was caught by the electricity, and the inside was burnt and tender, and black smoke fell down.

The military and civilians were first shocked, and then breathed a sigh of relief.

When the inner city was broken, they thought they were dead.

This is really a desperate situation.

The passage that was finally smashed was blocked, and the demons were of course unhappy and each showed their magical powers to attack. When the lightning and lightning that moved up the door was slightly reduced, the demon general drove the soldiers to break the door and asked them to tear the eye of the formation.

The talismans on the brass gate are all intimate texts, which are sunken inward and are easy to climb. In the blink of an eye, hundreds of demon soldiers climbed up.

Humans return arrows.

However, the demon soldiers were brave. When humans shot ten, hundreds of them continued to move up.

At this moment, one after another appeared out of thin air from the brass door...

"Fish fins?" The military and civilians at the city wall were very surprised.

If the wide door panel of the brass door is compared to a sea, then fish fins will break through the waves one after another, like triangular sails, pointed and tall.

The fish fins were cruising on the facade more and more densely, and they were heading towards the demon soldiers.

Immediately afterwards, they all dived and disappeared again.
