If he didn't get rid of Ghost Princess Ai'na, she would keep following him. He'd probably be annoyed to death.

After Ghost Princess revived using Kosa's body as a vessel, she immediately searched for Nie Yan's tracks, chasing after him.

All along the way, buildings collapsed into ruins under the impact of Ghost Princess Ai'na's massive body.

A black tentacle stretched out very long, smashing down heavily towards Nie Yan's location.

Nie Yan lunged forward, accelerating his Gale Step and running wildly.

With a loud boom, the ground was smashed, creating a terrifying deep pit.

Nie Yan barely dodged Ghost Princess Ai'na's attack. While running, he thought about how to deal with her. He took out Doro, the Headless Horseman's Crossbow, from his backpack, loaded five arrows, and pulled the trigger. *嗖嗖嗖*! Five arrows shot towards Ghost Princess Ai'na.

*Puff puff puff*, the five arrows hit one after another, and damage numbers of over 1,000 floated above Ghost Princess Ai'na's head.

However, looking at Ghost Princess Ai'na's health, which was over six million, it was impossible to kill her by shooting one arrow at a time.

Ghost Princess Ai'na caused chaos in Goring Town. Many non-combat NPCs ran around in panic. Those who could fight rushed forward, but they were quickly sent flying by Ghost Princess Ai'na's tentacles.

Ghost Princess kept hitting the ground, causing it to shake as if there was an earthquake, and shocking cracks spread rapidly in all directions.

These cracks were so terrifying that Nie Yan sensed danger. He accelerated and ran wildly into the distance.

Ghost Princess chased closely behind, and the sound of the ground collapsing was like an earth-shattering landslide.

The ground under his feet kept collapsing. Nie Yan used a Random Teleport Scroll. A white light flashed, and he appeared a thousand yards away.

He didn't know where he had ended up. Nie Yan was standing on a mountainside. The ground was still shaking. Looking into the distance, after the ground collapsed, a magnificent city beneath the earth came into Nie Yan's view. This city was sunken below the surface, about fifty to sixty yards deep, and was filled with densely packed buildings that stretched as far as the eye could see.

Nie Yan was stunned. He estimated that no one would have thought that there would be such a magnificent city under this vast desert.

He couldn't find Ghost Princess Ai'na anymore. What caused the ground to collapse just now? Ghost Princess Ai'na shouldn't have such great power!

Nie Yan suddenly remembered the Paternoster Battle Hammer in his backpack, which was emitting a dazzling light at this moment.

It seemed that the Paternoster Battle Hammer had triggered the appearance of the underground city.

A system notification sounded.

System: You have discovered the Lost City of Battle.

Immediately afterwards, a system announcement rang out.

System Announcement: Player Nie Yan has opened the Lost City of Battle. The Battle City map has been opened.

After this system announcement was sent out, the entire server was shaken, and players discussed the announcement.

"Battle City, what city is that, where is it?"

"Don't know."

"Just got news, Battle City is in the northern part of the Satrin Empire, originally within the Goring Town area, but Goring Town has sunk, and an underground city has appeared below."

Players quickly searched for information about Battle City. The keywords "lost city" and "sunk underground by demons" immediately attracted everyone's attention. However, what really interested the vast majority of players and those large guilds was that Battle City was opened by Nie Yan. Just being associated with that name was enough to be attractive.

What task did Mad Rogue Nie Yan trigger? What are the rewards for the task? Everyone couldn't help but let their imaginations run wild, and everyone could imagine that this task was definitely not simple.

Nie Yan's strength was already well-known to everyone, and his equipment was the envy of everyone, especially the Zennarde Sword, which was a divine-grade weapon! He didn't know what Mad Rogue Nie Yan was going to get this time.

These speculations made Battle City attractive, so the major guilds hurriedly formed teams and set off towards Battle City, getting there early to avoid having the items taken by others. Almost all the guilds formed teams and went to Battle City. The guilds' intense reaction made many players feel excited as well. Many of them spent their own money to hire high-level player teams to go to Battle City.

Leaving aside other places, the Assassin Alliance, led by Nie Yan, had released as many as five or six hundred missions related to Battle City, most of which were hiring players to form teams to go to Battle City together.

Players from all over the world poured into Battle City like a tide, creating an unprecedentedly grand occasion.

This scene caught Nie Yan off guard. It showed how influential the name "Mad Rogue Nie Yan" was to the players.

Nie Yan had just received news that Angel Corps and several guilds under the Century Financial Group had sent three ten-thousand-man legions over. It was really not easy to form a ten-thousand-man team so quickly.

In just a few minutes, Battle City became lively. They entered Battle City through various means and explored it.

A thought flashed through Nie Yan's mind, and he smiled slightly, entering Battle City as well.

The monsters that spawned in Battle City were all around level 150 or 160, and they were sand giants with high defense and only average attack power.

Shuttling through the alleys of Battle City, the buildings here were full of ancient style, with pointed towers rising one after another.

On the way, Nie Yan had already encountered a total of five player teams. Some of these teams had as many as a thousand or even several thousand people, while others had only a few hundred people. They formed teams to advance towards the center of Battle City little by little.

While Nie Yan was wandering in Battle City, he suddenly received a message from Guo Huai.

"Where are you now?"

"I'm in Battle City, what's wrong?"

"Sun, Xie Yao, and the others have returned from underground."

"So fast, did they gain anything underground?" Nie Yan asked. Calculating the time, Sun and the others had been underground for several days.

"They did a task and obtained two Legendary-grade equipment. In addition, they contacted Duo Duo and made a deal. It is estimated that they will earn at least twelve million gold coins this time. Besides that, he said he is willing to cooperate with us and attack Angel Corps together. He has already sent hundreds of thousands of players to the surface."

"Okay. It seems it's time to deal with Angel Corps," Nie Yan said excitedly. Although he was a little curious about what kind of feud Duo Duo and Angelic Feather had, Angelic Fall's willingness to attack Angel Corps with him was equivalent to adding a powerful ally to the Nirvana Guild.
