Ye Qingyu's words made Liu Shaji excited.

When you enter the gate of the Sword Tower, there is a shimmer light inside. You can see that there is an empty space inside, which is obviously a very clever space formation. It is like a huge training and training ground, with weapons frames, coaching platforms, marching tents, and airship port docks. Compared with the black marks burned by the imperial fire outside, the Sword Tower is much better. Various objects only have traces of smoke and fire.

At the end of the schoolyard is a black staircase leading upwards.

The steps were covered with traces of various battles, as well as the remains of weapons such as swords, spears, war halberds, etc., which were inserted on the steps.

"It's all imperial weapons."

Although these weapons have lost all their spiritual power, the law power contained in them has been completely destroyed, and the rust on them is no different from a pile of scrap copper and iron, Ye Qingyu can still see that these weapons were once the imperial weapon-level weapons, but unfortunately they were all destroyed in the war, and perhaps even their masters had long been killed in battle.

It is possible to imagine how tragic the battle back then was.

The battle in this black sword tower is more tragic than outside.

Following the black stairs, he walked past a stone gate. This stone gate was a teleportation formation, and it still had some effect today. Ye Qingyu pressed the stone gate with one hand to drive the remaining formation inside. A blue light flashed in the gate, and the formation reappeared again. The three of them walked like a formation, and the sound of ripples of water sounded.

The three were teleported to the second floor of the Sword Tower.

The second floor is still a schoolyard, but it is more refined. It can be roughly seen that if the first floor of the Sword Tower is to train ordinary soldiers, the schoolyard space on the second floor is to cultivate elite troops in the army.

From the scale of these two schoolyards, we can vaguely guess how powerful the military power of this black castle was at its peak. It is indeed to be more magnificent and more militarized, just like the Chaos Twenty-One City that exists in the vast world today. It should be an ancient city that advocates the army.

The three of them climbed the eighteenth floor in a row, all of which were all school spaces.

Even Ye Qingyu felt a sense of surprise.

In this way, this black sword tower is more like a military camp, accumulating terrible military strength. Along the way, I not only saw the broken imperial weapon, but also some dried corpses, with bones like the iron of the gods and immortals. You can tell at a glance that these corpses were definitely a powerful martial arts master who shocked the country during their lifetime, but they had been dead for a long time, at least for millions of years.

This ancient city is a completely militarized place.

Ye Qingyu carefully observed various traces along the way, which further confirmed his conjecture.

Finally, after walking through 107 stone gates in succession, the three of them came to the 108th floor of the stone gate - this Black Sword Tower Black Heart Castle, with a total of 108 years, which further confirmed Ye Qingyu's guess.

"Where is this place? Such a terrifying battle has happened." Liu Shaji sighed, his heart full of doubts.

Ye Qingyu walked to the last stone gate. This stone gate was more magnificent than any stone gate before, three or four hundred meters high. The door frame was engraved with ancient runes, which were patterns that Liu Shaji had never seen before. However, when Ye Qingyu saw it, he felt more confident in his heart because he had already recognized the origin of these runes.

"A betrayal happened here once." Ye Qingyu said.

He looked around and saw many corpses in this floor space, with ancient remains piled up like mountains. It is obvious that the most tragic battle has occurred on this floor. It can be roughly imagined that after the guards and invaders of this black castle had gone through a fierce battle, this place became the last line of defense and carried out the last and most tragic battle.

"Did Your Majesty already know what's going on here?" Liu Shaji looked at Ye Qingyu with curiosity.

Ye Qingyu nodded and said, "If I was not wrong, the former owner of this castle was named Ye Chuangsheng. The dark realm of the past was created by him. The twenty-four cities of Chaos Ruins in the Great Thousand World were also created by him. Many of the masters of Chaos City in the past were his subordinates. Once upon a time, he could be said to be the master of the entire Great Thousand World. Although he was not famous in the long history, he monopolized an era."

"Ye Rebirth?" Liu Shaji was stunned and shook his head. He had never heard of this name.

Ye Qingyu nodded and said nothing.

Ye Chongsheng once said that when he was almost dominating everything, he encountered a betrayal. Everything he managed was destroyed in this betrayal. The planner of the betrayal was the Emperor of Heaven who had been hiding in the dark for all times. Everything was overturned. Since then, the Emperor of Heaven began to control everything in the dark. For example, the guardian camp of the Dark Realm betrayed Ye Chongsheng's camp. However, all of this was actually within the calculation of Ye Chongsheng. He deliberately pretended to die and escape in this betrayal and reincarnate. Although this betrayal initiated by the Emperor of Heaven destroyed many arrangements of Ye Chongsheng, the real core arrangement was not affected.

These things were once said to Ye Qingyu during the Maze of the Black Demon Abyss.

However, when talking about these things at that time, for Ye Chongsheng, it was just a kind of memory of the past. Ye Qingyu's attention was also focused on the matter itself, but he never thought about how tragic such betrayal would be, where would it happen, and he did not expect that it would have something to do with the ancient city that disappeared from the Twenty-Four Chaos City.

Ye Qingyu also came to this black castle and inferred it based on many clues and clues.

Therefore, the original twenty-four cities of Chaos that were originally in the past have become twenty-one cities. The mystery of the missing ancient city of Chaos can uncover some mysterious veils.

The last stone gate is obviously the last level.

Even Liu Shaji could see that the enemy who invaded here did not break through this stone gate. In other words, after the betrayed by the Heavenly Emperor, he was blocked and unable to move forward. In the end, the Heavenly Emperor burned the entire castle with the Netherworld Fire, but failed to completely destroy it, so he could only retreat in disappointment.

The black castle has entered the turbulent flow of time and space. It may be the means of the Emperor of Heaven, or the self-exile arranged by Ye Chuangsheng.

The runes on the stone gate are the 108 ancient characters that have not been completely evolved.

Ye Qingyu saw the entire deduction process of the 108 ancient characters on the tombstone in the ancient city of Gods and Demons in the Black Demon Abyss.

Therefore, this stone gate that the Emperor of Heaven had never broken through with all his strength was just a pediatric department for Ye Qingyu. He used the rune technique and easily restarted the stone gate again.

After entering the stone gate, it is not the training ground.

Birds and flowers scented, a bright and beautiful world appeared in front of the three of them.

"Who?" Two figures rushed over from afar and shouted from afar.

Ye Qingyu smiled slightly: "I finally found you."
