Chu Wanwan looked over and saw a soldier who was about twenty years old, wearing camouflage uniform. He had a thin face but a strong build, and big, round eyes, giving him a very honest and simple appearance.

When he saw Chu Wanwan looking over, a blush rose on his face.

Xiao Liu stood up straight, a little nervous, his hands unconsciously clenching into fists. His eyes showed both awe for Chu Wanwan, the immortal, and excitement at being able to stay and assist.

He never imagined he would meet a deity, let alone such a beautiful female deity. He felt both apprehensive and filled with a sense of mission.

“Little fairy, I…I will do my best to assist you. I am very familiar with the underground environment of Kyoto City. I know every passage and every exit like the back of my hand.” Xiao Liu mustered his courage. Although his voice trembled a little, the determination in his words could not be ignored.

Chu Wanwan smiled slightly, her smile carrying warmth and encouragement. "Okay, with you here, I believe things will go even more smoothly. Don't call me a fairy, just call me Chu Wanwan!"

Seeing Chu Wanwan's approachable and unpretentious manner, Xiao Liu felt a warmth in his heart, instantly feeling much closer to this celestial being. He smiled憨厚ly, revealing two rows of white teeth, "Okay, Lady Chu Wanwan, I will definitely do my best to assist you!"

Chu Wanwan nodded in satisfaction; she liked this direct and pure enthusiasm.

She turned to Li Weiguo and said, "General Li, you should evacuate as soon as possible. I will notify you to return to the surface once the demons are destroyed."

"Yes, Fairy! If you need us, just have Xiao Liu go to the underground city on the outskirts of the capital to find us!" Li Weiguo bowed respectfully to Chu Wanwan before turning and following the main force to retreat.

Chu Wanwan then sat in the carriage, waiting for the battle report from the Immortal Realm.

Currently, armies are fighting demons on the surface of various cities. If they were to intervene rashly, the battle between the immortal cultivators and the demons could threaten the lives of these soldiers. Therefore, Chu Wanwan plans to wait until the Chinese army has completely withdrawn to the underground city before launching an attack.

After an unknown amount of time, a sudden burst of hurried and chaotic footsteps echoed through the subway station, accompanied by the deafening roar of demons and the terrified screams of soldiers. Chu Wanwan abruptly opened her eyes; in the pitch-black subway station, she could vaguely see large patches of firelight.

"Oh no!" Chu Wanwan jumped to her feet. "Turn off the lights, and be careful!"

As Chu Wanwan spoke, she didn't have time to think further and flew towards the torches.

In the blink of an eye, Chu Wanwan arrived at her destination.

In the firelight, hundreds of demons could be seen chasing the soldiers toward the subway station, their eyes gleaming with bloodlust and their mouths emitting chilling roars. The soldiers panicked and ran for their lives. Every now and then, a soldier would stumble and fall in the chaos, instantly swallowed by the demons, letting out a piercing scream.

Outside, rocket launchers could be used to slow down the demons' advance, but inside the subway station, the soldiers dared not use weapons with immense explosive power, and firearms were useless against the demons. Therefore, once an entrance to the subway station was breached, the soldiers were left with only one option: escape.

With a wave of her hand, Chu Wanwan conjured a massive wall of spiritual energy that separated the soldiers from the demons. The demons crashed into the wall with deafening bangs, but they could not break through this invisible barrier no matter what they did.

The soldiers breathed a sigh of relief the moment they saw Chu Wanwan; they were saved!

But they dared not stop, because several demons were too close to the army, and the spiritual energy barrier could not block them. At this moment, they were chasing after them. The soldiers' hearts were pounding like drums, rapid and powerful. They ran with all their might, and every step seemed to be on the edge of life and death.

However, some soldiers at the very back were still caught by the demons and torn to pieces.

Chu Wanwan quickly mobilized the spiritual power within her body, formed hand seals, and softly chanted incantations.

In an instant, the subway station was filled with light, and beams of light shot out from her hands, accurately hitting the demons chasing after the soldiers.

The demons howled in agony as they were bombarded by the beams of light, and then turned to ashes.

When the soldiers heard the howling behind them disappear, they turned around and saw that several demons had been reduced to ashes. They breathed a sigh of relief and looked at Chu Wanwan with gratitude.

"Wait!" Chu Wanwan said, heading towards the spiritual energy wall. She made a hand seal with her left hand and dispelled the spiritual energy wall with her right. The instant the spiritual energy wall disappeared, a green rune array blocking the passage appeared in front of the demon horde, and in the blink of an eye, the demons turned to ashes.

"Is this the power of gods? It's so powerful!"

"It seems they really are gods! We humans are finally saved, waaaaah..."

"Thank you so much, fairy, for your help!"

Excited cheers erupted from the subway station. The soldiers' emotions were running high, and their gazes toward Chu Wanwan were filled with admiration and gratitude.

Chu Wanwan waved to them, indicating that they didn't need to worry about it, and then continued, "Follow behind me, I will escort you back to the underground city."

Upon hearing this, the soldiers nodded and followed closely behind Chu Wanwan. They knew that with this fairy by their side, they could safely return to the underground city.

Chu Wanwan led her soldiers forward. At each subway station entrance, she reinforced the gates with spiritual energy, ensuring that only level nine demons could break through the barriers.

It took them a whole day to reach the entrance to the underground city. The entrance was in a ruin, an inconspicuous hole partially hidden by a few broken stone slabs and twisted metal. If someone hadn't led the way, Chu Wanwan would have had a hard time imagining that this was the entrance to the underground city.

Chu Wanwan also set up a barrier around the cave entrance before following the soldiers into the cave.

Upon entering, one is greeted by the stench of rotting corpses. Stepping inside, one realizes that there are indeed several severely decomposed bodies there.

"What's going on here? Aren't you going to clean it up?"

Chu Wanwan asked Xiao Liu, who was walking beside her.

"Demons have a keen sense of smell. These are corpses we specially summoned to mask the human scent emanating from the underground city!" Xiao Liu walked expressionlessly past the pile of corpses and followed a passage into a large, high-tech door. He didn't know what material it was made of, but it felt very advanced.

Li Weiguo extended his palm and gently placed it on the seemingly ordinary yet extraordinary high-tech door. Then, his fingers lightly tapped several specific spots on the door, as if inputting some complex command.

The patterns on the gate began to shimmer faintly, as if ancient, dormant runes were being awakened. Then, a deep, powerful mechanical roar resounded, and the gate slowly parted, revealing a passage to the underground city.

"This is the latest technological achievement of our underground city, which uses biometric and quantum encryption technology. Only authorized personnel can open it."

Li Weiguo explained.

"Can it ward off demons?"

Chu Wanwan looked at the heavy door and asked curiously.
