"Hmm..." Lou Fei'er snorted softly the moment Xu Xin touched her.

"Don't make any weird noises!"

"No! I..." Just as Lou Fei'er was about to explain something, Xu Xin noticed something unusual.

He discovered that the blood lines on Lou Feier's back that he came into contact with started to slowly light up.

this……

He used some strength.

Probably Lou Fei'er also felt that her voice just now was a bit embarrassing, so she suppressed the cry this time.

But her shoulders were obviously shaking.

The blood lines behind her and the places touched by Xu Xin slowly lit up.

"...How do you feel now?" Xu Xin asked with some surprise.

"It's just... very comfortable, very comfortable..." Lou Fei'er covered her mouth before she could finish her words.

She almost screamed again.

"Okay, it's done."

When Xu Xin saw her like this, she immediately stopped.

Although Lou Fei'er's back felt as comfortable as silk, and he also wanted to figure out what was causing the blood streaks to light up, but... now was not the time to do that.

"..." Lou Feier looked back at him, then went to get dressed without saying a word.

Xu Xin felt that she saw a trace of... resentment and dissatisfaction in her eyes?

...How did she feel just now?

Was the situation just now due to the contract?

The red lines light up when touched by him. Could it be... that it can enhance strength?

etc……

That Ma Hongwei and Qin Fu...

Xu Xin shivered directly.

……Grass.

He calmed down immediately, then quickly applied the medicine on himself and got dressed.

After applying the medicine all over my body, my whole body felt cold.

This is not very friendly to him now.

I hope this situation won't last too long.

He applied cocoa all over again, and his hair was a little wet.

"Uh-huh-huh!" Coco's little paw waved wildly to refuse, but it was of no use. In the end, it was painted all over.

The Silver King was put away.

"Okay, let's go down." Xu Xin glanced down.

Height of fifty or sixty meters.

It's all bugs.

"Jump down? I can't stand this height." Lou Fei'er also looked down, then shook her head.

It is indeed difficult to get down from this height, and it is also difficult to get up.

He directly used his watch to select today's historical increase: the increase in jumping ability.

Warmth flowed into his legs, and he immediately felt the long-lost strength in his legs.

"Coco, hold on tight!"

He didn't waste any more time and immediately grabbed Lou Fei'er's waist and jumped down from the edge of the pit.

…

"Where is this place..." Zeng Tao leaned against the wall helplessly, then sat on the ground, "How do you get out of this place!"

In the darkness, Zeng Tao and Jin Yue were resting by the gravel wall.

The two of them had just sat down.

They had just walked in this place for a long time, but they had never found a way out.

"This should be the relics of some civilization." Jin Yue was much calmer, "Perhaps, it's the relics buried underground."

Her previous experiences were much worse than now, and there weren't many things that could make her panic anymore.

"It does look like it." Zeng Tao looked around again, then lay down on the ground and shouted, "But...how can we go back? This place is too big..."

After they were swallowed by the ground, they quickly fainted from suffocation because they were stuck deep in the soil.

At that time, the soil was like a man-eating swamp, and no matter how strong you were, it was of no use.

When I woke up, I was already in this underground space.

This underground space is huge, with a height of about twenty meters, about six or seven stories high. The ceilings and walls on all sides are all wrapped in huge stone slabs.

It is obviously a space excavated and constructed underground manually.

And the things in the whole space are also a bit shocking.

Here, it seems to be a...

A smaller version of the city.

The layout of these buildings seemed to recreate an ancient civilized city before their eyes.

The low stone buildings look like houses of ancient residents. Each one looks extremely delicate, and you can see how much effort the people who made them put in.

Even if these buildings have been slightly worn over time and have been covered with thick dust, they cannot resist the visual shock.

The most eye-catching building is in the middle of the entire space.

It was a stone palace.

That's right, it's not a stone castle, but a palace, a beautiful palace that seems to be carved out of stone.

The highest position of the palace is only three floors, but it has reached the top of this space, indicating that the height of each floor is at least six or seven meters.

Set against the surrounding low buildings, the central palace looks extremely majestic, especially from the height to the ceiling, and the visual effect is very shocking.

"You said... what kind of place is this place?" Zeng Tao sat up and looked at the palace in the middle, "An underground city? But these buildings have obviously not been used for a long time? They are all dust..."

The two of them were heading in the direction of the palace. They were further away from the palace just now.

On the way, they also entered many low stone houses, but unfortunately, the interiors of these stone houses were empty.

There was nothing but thick dust on the ground.

Even the walls are made of exposed stone slabs without a trace of whitewashing.

To put it simply, it is a rough house that has not been decorated at all.

It was as if no one had ever used these houses before they were built.

"I don't know." Jin Yue shook her head, "Maybe, it's like the underground city we experienced before?"

"...That's too much of a difference." Zeng Tao stood up, "Let me tell you, this might be the... underground world that Xu Xin and the others went to? Are we also setting out on a mission to explore the underground world?

?”

"I don't know, but the palace in the middle may give us the answer." Jin Yue looked at the palace and said.

"Then we won't rest. Qin Fu might be here too. Let's... um?" Zeng Tao was about to say let's go, but suddenly her eyes widened slightly, and then she frowned, "Hey, did you... hear that?

what sound?"

"I heard it. Over there." Jin Yue pointed upward with her finger, her expression slightly becoming serious, "The ground is also shaking slightly..."

Not just a slight vibration.

After Jin Yue said these words, the shaking on the ground became stronger and stronger.

"Something is coming!" Zeng Tao looked behind them, where they had just woken up, and where they had moved away, "Just above our previous position...ah!"

"Click!"

"boom!!!"

The ceiling above exploded the moment Zeng Tao pointed!

Rocks flying!

Then, a giant insect with blood streaks on its gray-white body blasted open the stone slab from above and suddenly came out!

"This...!" Zeng Tao's eyes widened and her mouth opened wide.

"...mutated giant insect!" Jin Yue was also shocked.
