Chapter 3911 It Will Cost a Lot

Everyone present was very concerned about this issue.

Ning Xi nodded: "We found it, but it's hard to destroy it!"

"His eggshell is very hard, and the key is that it is wrapped in a layer of very strange energy. It's hard to break it."

"What power? Does it belong to the Insect King?" Lan Jinbing asked.

Ning Xi replied: "I don't think it's the energy of his own eggshell. It's more like it's borrowed from the outside, but we can't tell what it is."

Luo Yinhuang took out the image and breath imprinted by the formation in his body at this time, "Dear Taoist friends, you are knowledgeable, can you tell what kind of energy this is?"

Several powerful people in the Tribulation Period looked carefully.

Lan Jinbing and others shook their heads, "I really can't tell what it is, but from the breath, this energy is very strong. We shouldn't be able to break this layer of protection by combining forces."

Just when Ning Xi was disappointed, the Undead King waved his hand, and the formation ball fell into his palm.

He extracted a wisp of breath and carefully identified it, with horror in his eyes.

"Do you know what this thing is?" Ning Xi looked at him and asked.

The Undead Emperor nodded: "I know, this is the energy of the core of our interface."

"Core energy?" As soon as this was said, the faces of the cultivators in the Crossing Tribulation Period changed.

Ning Xi didn't know much, "What is the core energy of the interface?"

"It is the core of our interface, that is, the energy that provides our cultivation world." After all, the Undead Emperor was a high-level cultivator in ancient times and knew more.

Ning Xi's face also became more solemn, "The Insect Emperor actually found the interface core to use, will it have an impact on our interface?"

The Undead Emperor thought for a while and said: "He is not a cultivator of this world, it is impossible for him to control the interface core and take it for himself."

"It's just that he may have used some secret method, and then extracted the power of the interface core for his own use. Over time, the interface core will gradually weaken, and the spiritual energy of our interface will become worse and worse."

"In the short term, the impact is not great, but in the long term, the impact is far-reaching, and it is even possible that the path of cultivation will be cut off after ten thousand years." He really didn't exaggerate.

The faces of the Tribulation-crossing cultivators present changed again, "Damn, this Insect King is so damned!"

"No wonder he has always been so fearless, it turns out that he has been extracting the power of the interface core for his own use."

Ka Tianhan couldn't help looking at the Undead King and asked, "Then what should we do?"

Others also looked at him, "Do you have any ideas?"

The Undead King said, "The most effective way is to completely kill the Insect King."

Everyone sighed, "But the problem is that we can't even break the eggshell, how can we kill him?"

They only knew that the Insect King was very strong before, but they didn't expect it to be so strong that so many of them in the Tribulation-crossing stage joined forces to attack and it was difficult to destroy the opponent's eggshell, let alone kill him.

The Undead King pondered for a moment, "In fact, it is not impossible to break the interface core power and his eggshell, but it requires a great price."

"What price to pay? Just tell us directly, if we can't kill the Insect King now, this interface will be over!" Several Tribulation-crossing cultivators asked anxiously.

The Undead Emperor replied, “Use a secret method to disperse the cultivation of two Tribulation-crossing cultivators from this world and inject it into the body of a person from the outside world, who will then break it.”
