Such an underground space is bound to have dedicated ventilation shafts, and during the day, Liu Yun was preparing to transport items through the ventilation system.

Most ventilation vents and air purification devices are electronic products.

Aqi could completely manipulate the flow of the special, powerful sedative through the air to every corner above and below ground.

Even if there are extremely secluded and special places, it doesn't matter.

It's the same as finishing her off once she gets here.

This one move alone is enough to take down more than 90 percent of people.

Not only the source of air circulation, but also the water source was tampered with.

Although there might not be many people using water at this time, taking down even one person is better than nothing.

When Liu Yun came in, there were only a few people who were still able to move around.

The corridors are like a maze, with secret rooms everywhere.

Some people fainted while walking.

Some people do things, and while doing them, they suddenly lose consciousness.

Some people managed to hold on and would press the emergency alarm when they realized something was wrong, but no matter how many times they pressed it, there was no response.

Some people realized what was happening and ran outside, and then... fainted in the corridor, or they ran into Liu Yun.

"Who are you?"

A person engulfed in flames, as if emerging from fire, was clearly enduring great hardship.

Although he reacted in time and used his superpower to protect his entire body, he still inhaled a few mouthfuls.

The current situation within the body is also not optimistic.

Upon seeing Liu Yun's appearance, he subconsciously asked the question.

Liu Yun ignored it completely, and directly pulled out a throwing knife and threw it, which hit the dantian purple mansion.

Although she hadn't studied the superhumans in this world, energy is generally stored in the dantian.

Once the dantian is destroyed, no matter how strong one's abilities are, they will be rendered useless.
