After crossing over, he has no taboos among the zombies.

Qin He took a look and saw that it was a gap that had collapsed due to the earthquake. It was pitch black and should have been covered by ice, but was exposed after the collapse.

The gap was not regular, only wide enough for two people to move sideways. Qin He moved sideways to avoid it, but was pulled by Dayajin's rope and staggered. The two of them stumbled and rolled directly into the cave entrance.

The sound of the ice spikes piercing the soil behind me was like a thousand arrows shooting at the same time, piercing into the cave wall along with my hair, and ice crystals splashed on my skin, bringing an astonishing chill.

"Let go!" Qin He grabbed Dayajin's shoulder blade with his backhand and squeezed it hard.

"Ouch, it hurts, it hurts!" Big Gold Tooth suddenly let out a howl like a pig being slaughtered, and as the rope that bound him loosened, he fell to the ground with a thud.

"Boom!"

At this moment, the gap suddenly collapsed, cutting off the inside and outside.

The cave suddenly became dark, with only the faint blue light emitted by the ice dragon seeping in through the cracks in the ice.

Dayajin fumbled and tore off the leather bag around his waist, and took out a night-shining pearl as big as a fist.

The pearly light revealed mottled marks on the cave wall, which turned out to be some kind of ancient inscription.

"What is this?" Big Gold Teeth's eyes widened when he saw this.

Qin He was also quite surprised. Why did he fall down so easily?

"Roar!"

There was no time to observe carefully. Outside the cave, the frenzied ice dragon tried to break through the ice and enter.

However, its movements exacerbated the collapse of the ice.

Qin He and Da Jin Ya hurriedly ran inside and left a long way until the noise became a little quieter.

At the same time, the two discovered that these ancient inscriptions were actually vibrating and emitting dark red water ripples. They were actually spontaneously resisting the vibrations from the outside and starting a kind of autonomous protection.

Otherwise, a mere layer of ice would not be able to stop the ice dragon with ice attributes.

"It can't get in!" Dayajin said when he saw this. "There's a formation set up here, and it's a very powerful one."

Qin He looked at the inscription carefully, his fingers slowly stroking the ice crystals condensed on the edge of the inscription.

Those lines were actually absorbing the extremely cold air from the ice lake of the ice dragon, and were faintly glowing.

"Look at that~"

Dayajin suddenly pressed Qin He's shoulder and pointed to a place deeper in the center.

Qin He looked around and saw dozens of ice spikes hanging upside down like suspended swords. In each spike was a frozen corpse, dressed in different clothes. They had expressions of fear on their faces, their last expressions frozen by the ice.

The two walked over and saw a pool of blood beneath the icicles.

Qin He glanced at the nearest corpse and did not find any special marks.

These people should all be night watchmen.

A tube was inserted half an inch above the chest of the frozen Night Watchman, with icicles sticking out. Drops of red blood flowed out like oil that was so thick that it was almost solidified.

But by this time, these people had completely dried up, and even the pool of blood below had solidified.

There are blood grooves around the blood pool, but they are also no longer flowing.

Looking around, this place is dozens of feet in radius, and dense inscriptions almost cover the entire place.

"This is some kind of formation, set up under the thick ice lake. It is rarely visited by people. It's quite a grand project." Daya Jin opened his eyes wide, unable to believe it.

"Can you tell what kind of formation it is?" Qin He raised the corners of his mouth slightly, and a feeling of joy surged in his heart.

He asked on purpose, and within ten breaths of entering, he had confirmed it.

This is a teleportation array.

It's a very bold idea. The reason why it's called an idea is that it's not complete and seems to be some kind of experiment.

But then it was interrupted. The people who were frozen in the ice died, their blood dried up, and the entire magic circle almost froze, with only the protection still playing a 10% to 20% role.

"It seems to be... an energy formation, using human blood as a guide to activate the formation, but it seems to be incomplete. Could it be a killing formation? Someone wants to kill the Ice Dragon?"

"The fugitive must be the fugitive!"

Da Ya Jin slapped his thigh and said, "In Sin City, apart from the City Lord's Mansion, only the fugitives have the energy to set up the formation."

"Kill the Ice Dragon?" Qin He shook his head secretly.

How could a teleportation array be used to kill the ice dragon? But it must be said that Daya Jin still has some insight and knows that most of the formations here are part of the energy supply array.

Humans are the most intelligent creatures in the world. In witchcraft, humans are also a kind of material, and a material similar to a panacea that can do anything.

If some complex functions cannot be realized, then killing people and taking their blood can basically serve as a substitute.

Although the substitution effect is very weak, it can be strengthened by other methods to achieve a power of 30% to 40%.

If it is not achieved, it means not enough people have been killed.

Of course, monster blood is also acceptable, each taking what they need.

"Teleport?"

Qin He couldn't help but ponder. In the Sin City suppressed by the ultimate magic circle, teleportation was like swimming in copper and iron. It was extremely costly and the effect was poor.

Those who run fast are not necessarily worse than this.

There is a lot of logic behind this.

Could it be that he wanted to teleport outside and escape from the city of sin?
