Looking at the Gate of Hell, which was still unscathed under the concentrated bombardment of a large group of poisonous explosive insects, Xue Hua also felt a little helpless.

It's so hard that they don't know what it's made of, and they can't seem to damage it with the means they have.

How can this be good?

You must know that the ultimate goal of the "Cleaner Project" is to destroy the gates of hell, and if they can't destroy this troublesome gate that connects to Chaos Purgatory, all their previous efforts will basically be equivalent to doing nothing.

Without cutting off the reinforcements of hell, no matter how many demons are killed, it will not help, not only is it time-consuming and laborious, but it will also fail to solve the fundamental problem.

Just when he and the other legendary professionals felt extremely troubled, the two transcendent beings, Skeleton and Eagle, suddenly appeared from their side.

"You can't destroy this door like that, and don't guess what it's made of, because the key to the problem is not the material at all."

"Yes, the Gates of Hell are made of Hellstone, and although that thing is hard, it is not so hard that it is impossible to be self-healing."

The two transcendents briefly explained a few words, and then shot together, and two sharp attacks slammed into the door frame of the stone gate.

However, the Gates of Hell still stood unwavering under the attack of the transcendents, except for a few rifts in the area where they were attacked, and they quickly recovered themselves......

"See, even the two of us can't help it, so a direct attack has no effect."

"Uh... So what should I do, I can't just give up, right? ”

Xue Hua asked helplessly.

"All permanent portals have a 'cornerstone', and this cornerstone is the key to stabilizing the portal passage and providing it with energy, as long as this cornerstone can be found and destroyed, no matter what kind of portal can be maintained."

The eagle looked at Xue Hua and nodded, and then explained briefly.

"I see, portal cornerstone......"

Hearing the explanation, Xue Hua immediately remembered the large permanent purgatory portal on the other side of the Doom Hollow, and Lilia was trapped by Xue Hua and the insect swarm because she was trying to snatch the cornerstone of the portal.

In this way, the portal cornerstone should be a precious item with a strong psychic field!

And since a permanent inferno portal needs to use the parts of the suit's real body as the cornerstone, isn't the cornerstone of the portal under the hell gate an artifact-level thing?

Although there has never been such a concept of "artifact" in this world, Xue Hua really can't imagine what kind of words should be used to describe the items that can surpass the real body of the "Incarnation of Tagio" series of sets.

Thinking of this, he immediately became excited: "That means that there is something more powerful under this hell gate than the real body parts of the suit?" ”

"Hmm... Logically speaking, this is true, but we don't know what it is......"

The eagle and skeleton looked at each other, then shook their heads together with a frown.

"Then what are you waiting for, just dig it out!"

Xue Hua looked excited, after all, it was an "artifact", how many times can this kind of opportunity be in a lifetime if he can dig out an artifact?

"Where is it that simple, are you a fool when Diablo and Baal are, they must have set up a large number of defensive mechanisms and spells in this underground, and it is impossible to dig them out for you directly so easily."

"It's not right to hit or dig, so what should I do?"

"Actually, it's very simple, the method of destroying the gate of hell has been studied by the council for a long time, and according to the information obtained from various sources, the cornerstone of this gate of hell should automatically absorb the power of this world to fill itself.

It does so by transforming an ore that is the Lighthouse Crystal used to fuel the Beacon of Hope in our rear towns! ”

"So there should be a huge lighthouse crystal ore vein down here, and we just need to find a way to dive deeper underground from the other side and mine all the lighthouse crystal ore in that lighthouse crystal vein, and we can play a role in the foundation of the hell's gate.

Once the energy supply of the cornerstone is lost, the traps set by the King of Dread and the King of Destruction will also be completely and completely invalid, so that we can dig the cornerstone out safely. ”

The skeleton and the eagle looked at Xue Hua at the same time.

"But to do that, we need the power of your minions......"

"Yes, although we are transcendent, it is impossible to go to such a deep underground without spending a polar day......

"I see." Xue Hua nodded, understanding why the two transcendents would explain so many things to him.

"It's not a problem, I'll be able to arrange it right away... But I'd like to go down and see ...... together."

Xue Hua scratched his head and said with a smile.

"Hahaha, I knew you would say that... It's fine, let's come along, but you'll have to listen to us when you get there. ”

"Well, there are suspected energy fluctuations of unknown origin in that crystal vein, and we suspect that Diablo and Barr have set some traps there as well......"

"Okay, no problem!" Xue Hua agreed.

"Then let's go outside the city, where we should be able to avoid all the traps and defensive spells set by the two demon gods."

With that, the two transcendents spread out and flew straight in the direction of the outside of the fortress.

Xue Hua also spread his Bone Wings, ordering Zagala to mobilize a Void Borger and a few hundred worker bees to stand by outside the city, and temporarily handed over the duties of commander-in-chief to Hodge.

Then he glanced at the battlefield of Anne and Funia not far away, and the two girls had already begun to get better.

With Quarkec taking care of it, there shouldn't be any problems.

Thinking of this, he shook his wings and followed the two transcendents directly towards the outside of the fortress.

The three of them quickly arrived at their intended destination, which was a deep rift in the ground.

"It's right here, it's deeper, it should be better to dig a little better."

"Xue, it's your turn."

"I see!" Xue Hua nodded, calling out to the Void Digger in the mind of the main nest.

Soon the ground around them shook, and dozens of seconds later, a huge insect as large as a pipe burst out of the rock from under the ground with a bang!

"Oh! It's huge......" The eagle looked amazed.

"Yes, Xue, your servants are really rare to see." The skeleton nodded, clearly agreeing with his companion's opinion.

"Haha, the two of you have won the prize, but let's get started."

As they spoke, the Void Digger had already retracted its massive body beneath the ground, leaving only a massive, sharp-toothed mouth on the ground.

Xue Hua jumped directly into the mouth of the Void Digger without hesitation, and the two transcendents jumped in directly with him without the slightest timidity......
