The three each harbored their own thoughts, knowing that each had an energy crystal, but Yuri and the Hongmen Ancestor were fundamentally not on the same side, and Lin Mo certainly wouldn't stand with the other two. The three formed a balance for now, maintaining a temporary equilibrium.

"Now we need to find a way to leave here, have you explored this palace yet?"

Lin Mo asked.

"Not yet. As soon as we reached this palace, we ran into these guys. Outside, I could take them out with one hand; they really dared to kill me," Yuri said venomously.

"Everyone came to this ancient battlefield ruins, and must have noticed our powers are suppressed, and many beasts have energy crystals inside them. The two of you must have harvested quite a bit, right?"

Lin Mo casually asked.

But the faces of the Hongmen Ancestor and Yuri visibly changed. The Hongmen Ancestor nodded, "But carrying things out without knowing how is also a problem."

"Let's first see if we can find any clues in this palace?" Lin Mo proposed.

The Hongmen Ancestor and Yuri nodded.

The three guarded against one another and began to search the palace. Although the palace's architecture was large, many things had been destroyed and buried in the yellow sand. Occasionally, a few skeletons would emerge from the sand along with rust-covered spears and broadswords.

The three cautiously proceeded inside, quickly reaching the interior of the palace, where a fresco depicted many angels soaring through clouds, and another portrayed an angel radiating a golden halo, with a group of worshippers kneeling on the ground.

"This must be the angels' stronghold?"

Lin Mo looked at a scene where an angel wielding a Light Sword pierced a demon with horns on its head, pondering that it was totally different from what he had seen in another palace.

In this place existed several ancient dynasties, which were then commanded by the angels and demons, leading to a large-scale war, resulting in the existence of the ancient battlefield ruins.

"Look at this..." Yuri widened his eyes.

Lin Mo and the Hongmen Ancestor looked over, seeing an angel flying to the sky, where a vortex entrance appeared. "Could this be the way out, but we have no mana, how can we leave?" Lin Mo frowned.

Yellow sand covered the earth, with an expanse of gray all around.

Only a black shadow faintly stood in the midst of the yellow sand, magnificent and grand, filled with an ancient aura.

The passage was found, but none had any mana to fly into the air to explore that passage.

"We should act together, search here to see if there's any discovery, this damn place," Yuri cursed with a frown.

Lin Mo stayed silent. Indeed, hunting beasts here could yield top-grade energy crystals, while outside, just one top-grade crystal could make superpower users fight to the death.

In this ancient battlefield ruins, many beasts that mutated by absorbing energy crystals were powerful, but slaying them would yield energy crystals, making it easier to obtain.

Even if he acquired energy crystals, without leaving, it wouldn't be good news for Lin Mo.

Carefully, the three moved towards the palace interior, clearly larger in size and structure than any palace Lin Mo had seen before.

Their pace was slow, but after an hour they seemed to reach the palace's interior, incredibly magnificent, with round pillars about twenty meters high, covering an area akin to a football field. Oddly, the floor was carved with bluestone slabs, with no sign of yellow sand.

"This place looks strange, everyone be careful."

Lin Mo frowned, reminding them, as he quietly held a black dagger in his hand.

Yuri and the Hongmen Ancestor automatically glanced at the dagger in Lin Mo's hand.

Yuri also took out a stone and held it.

The Hongmen Ancestor drew a black whip that looked like a little snake, showing that the two indeed prepared for entry into the ancient battlefield ruins.

"Careful."

A small breath of wind appeared on Lin Mo's left side, instantly detected, a shadow charged at him with such speed that reacting was nearly impossible.

But Lin Mo's body suddenly twisted to the right, narrowly dodging the shadow, which then landed on the ground.

The Hongmen Ancestor, Yuri, and Lin Mo looked first.

A giant wolf, about two meters tall with gray fur all over, leaned forward, its icy eyes glinting with bloodthirsty light. Most peculiarly, a five-centimeter silver horn grew from its forehead, like metal, giving a cold feeling.

"Beast!"

The Hongmen Ancestor cursed, waving his black whip like a dragon, turning into a shadow with a sharp rumble, faintly visible were wisps of blood fog around the whip.

The lightning-quick black whip struck, the giant wolf couldn't react as the whip hit it, making it roll away, weighing two hundred to three hundred pounds, yet one whip sent it rolling away, showing the power's magnitude.

Yuri and Lin Mo frowned simultaneously.

The Hongmen Ancestor's whip was a Grade Four Treasure, even without mana, its power couldn't be underestimated.

Lin Mo regretted not taking out the Xuanyuan Sword earlier, which would have provided better protection.

"Hou!"

The giant wolf agilely rolled, stood up again, fiercely glaring at the Hongmen Ancestor, its waist bore a blood trace, with blood continually seeping out, staining its fur, clearly enraged after being wounded.

Its strong limbs flicked rapidly, its claws ejecting like steel blades, each about ten centimeters long, emanating a cold metallic sheen, capable of causing significant destruction.

"Quickly kill it, it's calling for companions." Yuri exclaimed fearfully.

With that, Yuri clutched the stone in his hand, covered in golden thunder, crackling, a lightning snake leapt from the stone, leaving a white flash in view, striking the giant wolf.

Clearly, the giant wolf was cautious now, leaping fast, though its bulk led some lightning snake to brush its body, causing convulsions, its fur blackened and smoking.

The giant wolf landed, its steel claws scraping marks on the bluestone, two eyes glowed red, furious by these humans enraging it, it growled lowly.
