Zero Zone: Start as Morax.

On the surface, today's New Eilidu is bright and beautiful, with tall buildings and advanced technology in the city center, comparable to the prosperous capitals of the old times.

If you have countless Dingni, you can move to the city center and enjoy the prosperity.

but.

Such a prosperous scene is only limited to the city center area.

Other areas, including the Janus district where the Rabbit House is located, are under threat of hollowing out.

There’s no telling when a disaster might strike, and the entire neighborhood could be swallowed up by the hole.

For ordinary people of New Eridu, this is the cruel norm and the other side behind the prosperity of New Eridu.

The black market, agents, rope makers, and smugglers all emerged under this cruel norm.

Su Li takes his client Cass through the black market.

Along the way, they saw all kinds of contraband that could not be seen in public, fake certificates from the Public Security Bureau, the Defense Force, and the Anti-Air Special Operations Department, all kinds of banned weapons and equipment, guns, ammunition, artillery, banned drugs, and all kinds of animals that had been mutated by etheric corrosion...

even.

We also saw several strange people who were infected by the ether and had black spots all over their faces. They hid in the underground black market to escape capture by the Public Security Bureau.

Su Li had seen this scene several times.

But when Mr. Cass saw this scene, it seemed that the painful memories of the past were awakened again, and his face became more and more ugly.

He clenched his fists tightly.

He found a trash can and started retching.

Su Li said slowly: "There is a music store in front, let's take a break and go there to have a look."

Mr. Cass finally calmed down: "No need to rest, let's go now, I don't have much time..."

It won't be long.

The Public Security Bureau will track him down based on the clues, and once he is wanted by the Public Security Bureau, it will be difficult to find that Yin Qing.

He must find the sound engine with Su Li's help before the Public Security Bureau finds him, and then take the engine to the railway tunnel to end everything with the notorious Yihai.

soon.

Su Li and Mr. Cass entered the Yinqing store together.

Although it is called an audio engine store, there are actually not many engines in the store, only some low-level or defective audio engines.

After searching for a while, I still couldn't find the target of the mission.

Mr. Cass's eyes showed a trace of disappointment: "Mr. Su Li, please take me to the next black market or Yinqing store."

Su Li nodded slowly and said, "Follow me."

The whole morning.

Su Li took Mr. Cass to walk all over the Janus District, visited a black market, two music stores, and even the music store on Liufen Street.

Target audio engine not found.

noon.

At the request of Mr. Cass.

Su Li took him to other neighborhoods and searched several audio equipment stores but found nothing.

at last.

Su Li asked, "I wonder what kind of sound engine you are looking for?"

Cass leaned against the wall dejectedly. "It took me three years and hundreds of experiments to create the protective sound engine. Others think it is useless and will become a piece of scrap metal once the skill is triggered. But those people don't know that in addition to the protective effect, the sound engine is also a sharp weapon for attack."

Hear this.

Su Li frowned slightly.

It is a protective sound engine that will turn into a piece of scrap metal once the skill is triggered?

He seems familiar...

aside.

Mr. Cass said to himself, "If I can find that sound engine, I'll have a chance to kill that damned locomotive."

but.

Seven years have passed since the creation of that sound engine.

Due to various reasons, Yin Qing had already fallen into the hands of others.

Maybe it has already been used by some cave robber and turned into scrap metal...

It may also be collected by some enthusiasts...

Mr. Cass has made up his mind.

Even if he couldn't find that Yin Qing, he didn't plan to linger on any longer. It was time to find out everything.

Just as Mr. Cass was reminiscing about the past.

Su Li suddenly asked: "Is the name of that Yin Qing called Guardian Angel?"

Hear the words.

Mr. Cass was stunned for a moment, and a glimmer of hope ignited in his eyes as he looked at Su Li: "Do you know the whereabouts of that Yin Qing? Mr. Su Li, where did you know this name?"

Su Li smiled slightly, showing an expression that said "as expected".

immediately.

He reached his hands behind his back.

He took out the life-saving engine that Nicole had given him before. It was small and looked like a piece of armor. It was obvious at first glance that it was a protective sound engine.

It is the A-level audio engine - the guardian angel.

The moment I saw this sound engine.

Hope rekindled in Mr. Cass's eyes. He quickly stood up from the ground and took the sound engine from Su Li.

"I finally found... the Cunning Rabbit House. You really didn't let me down."

A hint of joy appeared on Mr. Cass's thin face.

However, this joy did not last long. It quickly disappeared from his face, and was replaced by determination.

Mr. Cass said seriously: "Thank you, Mr. Su Li, your commission has been completed."

Su Li saw traces of the story on Mr. Cass's face, and he said lightly: "You seem to be going to fight, don't you need my help?"

Mr. Cass didn't want to implicate others: "I am enough on my own. That Yi Hai is very strong. Even if you come, you can't help."

It’s not that he underestimates Su Li.

It was because the scene ten years ago was still engraved in his heart. He saw with his own eyes the huge skeleton rushing around and smashing his lover to pieces...

He wanted to protect his lover, but he could do nothing. He could only watch the wreckage, which looked like a locomotive, disappear into the ruins.

That feeling of fear, powerlessness, and anger... He still hasn't forgotten it to this day.

This is also the reason why he survived for several years, waiting for revenge.

Recalling the scene of that year again.

Mr. Cass turned his head away and put his hands over his head.

Su Li reminded: "Tell me your story, maybe I can help."

Mr. Cass took a deep breath and narrated slowly: "Ten years ago, I was a genius audio researcher. I was a supernova in people's eyes. I was the kind of genius who could earn a lot of money and buy a house in the city center..."

"But until that day, the so-called locomotive attacked the train. Except for me, everyone on the train died, including the driver, passengers, management... and my love..."

"I clearly have so many sound engines on me, but none of them can help me stop Yi Hai. I can only watch the tragedy happen."

"From that day on, my research and development ideas changed. I used all protective materials to develop the Sound Engine, and added all the attributes to defense... I created an ether force field inside the Sound Engine that could block the attack of the Infamous One... Finally, I put all this together and created the Guardian Angel that everyone called useless..."
