"Proving ground?"

Li Qingyan murmured in a low voice, with a hint of sarcasm on the corner of his red lips. He glanced at this huge ancient city and chuckled like a sigh: "Those high-level officials from thousands of years ago were so courageous. They actually built a prison to house millions of people.

Proving Ground?"

Xu Yuan looked at her expression and smiled helplessly:

"This is probably a helpless move. The remnant soul in the soul ring once said that the human race thousands of years ago has reached extinction."

"Prince-in-law, I am not completely ignorant of the great calamity that occurred thousands of years ago."

Li Qingyan lowered his eyes and glanced at his palm, which was wrapped in maroon armor, and then squeezed it:

"I'm just wondering if I could make the same correct decision as them if I were in the same position."

The right decision.

Xu Yuan narrowed his eyes slightly, then looked at her and smiled softly:

"It's unfounded to worry. If a disaster strikes, I believe you, Qing Yan, can make the most correct decision."

Li Qingyan chuckled:

"Are you so sure?"

Xu Yuan shook his head and stared into her eyes:

"I'm not sure, but I know that when a race faces extinction, kindness and compassion cannot save the world, only iron blood and authority can."

Li Qingyan was silent for a moment, stared at Xu Yuan with interest, and asked deliberately:

"If this is the case, what is the difference between humans and beasts?"

Xu Yuan rolled his eyes at the princess, with a strange smile in his voice:

"Your question makes me feel like you are talking to my fourth sister."

As he spoke, he curled his lips:

"Qing Yan, you have been fighting against the barbarians for more than ten years. You should know the answer to this question better than I do. The validity period of benevolence, justice and morality can only be maintained within peace."

"Humph."

Li Qingyan laughed crisply, his phoenix eyes curved into crescent moons, and there was a touch of excitement in his eyes:

"Changtian, you and I really get along well."

"Don't call me Prince Consort?" Xu Yuan asked softly.

Li Qingyan tilted his head playfully:

"Wouldn't it make me more friendly to you if I screamed in the sky?"

Xu Yuan shivered and complained:

"Cute expressions don't suit you at all."

"Humph."

Li Qingyan snorted coldly, shook his head boredly, and his expression instantly returned to his usual noble and plain expression:

"Enough nonsense, Changtian, since you know that this is a testing ground for captive white ghosts, you should also know how to control the formation of this underground palace, right?"

Xu Yuan's eyes showed a hint of approval.

Her words are still simple and clear and go to the center of the problem.

Just like those movies in previous lives, experimental bases for studying viruses always have layers of security measures.

If this is an experimental site for studying the transformation of humans into White Walkers, then there must be a formation to control White Walkers.

Otherwise, the "human race" here would not be able to last for thousands of years.

But it's a pity

Xu Yuan shook his head directly:

"I don't know."

"Huh?"

Li Qingyan was stunned by Xu Yuan's answer, and then asked:

"But you said before that the way out is around here."

"I said you relied on the formation to get out?"

"."Li Qingyan.

Xu Yuan glanced at the interior of the ancient city and whispered:

"Let's go to the city first to find that "Master Si Ming" and ask her about the situation here."

"Find"

Li Qingyan subconsciously wanted to refute, but after Xu Yuan finished speaking, he directly raised his palm and stared at her quietly.

Eye to eye,

Li Qingyan glanced at his raised palm, and after a slight hesitation, he swallowed his words with a cold voice:

"Okay. It's up to you."

Xu Yuan smiled slightly and explained:

"The tunnels near this cave extend in all directions. It will be difficult for the two of us to find the exit. It will be much easier to talk to the "Si Ming" and ask her to mobilize her people to help us search together."<

/p>

The words fell,

The two of them jumped across and disappeared directly at the top of the city where panic was spreading.

Although this underground city is large in area, it is a bit scary inside.

There was no sound in the blocks near the city wall. Walking on the street felt like walking in a ghost town in the underworld, and the surrounding darkness shrouded the two of them like ghostly aura.

The layout of this ancient city is somewhat similar to the mortal cities in Xu Yuan's movies and TV shows in his previous life. There are no official roads for monster carriages like those in the cities in Dayan, and the city planning is also in a mess.

The main roads and side roads are complicated, and commercial blocks such as Fangshi Winery and residential buildings are mixed together. You can vaguely see the prosperity here thousands of years ago.

But now, these dilapidated houses may only need a gentle push to turn them into ruins.

Before he had gone far, Li Qingyan suddenly took his hand, looked at the sky in the distance, and said with a strange look:

"Someone is here, and the breath is not too weak."

"Oh?"

Xu Yuan raised his eyebrows. To be able to make Li Qingyan comment like this, his cultivation level can only be above the Grand Master level: "Then Si Ming is actually a powerful Grand Master?"

Li Qingyan's phoenix eyes flickered slightly, he felt for a moment, and then uttered two words:

"More than that."

Xu Yuan's pupils shrank when he heard this:

"Yuanchu?"

"Hmm."

Li Qingyan nodded slightly, paused for a moment, and then continued: "She discovered you."

Having said that,

She slowly took out her sword from the Sumeru Ring.

"."

Xu Yuan's eyes twitched when he looked at her indifferent expression.

No, sister, you are a military formation cultivator. Can you beat an ordinary Yuanchu and be so calm?

After a moment of silence, Xu Yuan said with a smile:

"Ordinary people who cultivate military formations should not be cultivators."

"Changtian, do you think I am an ordinary person?"

"."Xu Yuan.

Damn it, all geniuses deserve to die.

Except Da Bing Tuozi.

After thinking for a moment, Xu Yuan let the other party go.

Although I don’t know why a strong man from the origin can appear in the ground where this bird doesn’t poop, but as long as the language is smooth, it means that communication can be achieved.

And according to the current situation in this underground ancient city, there is a high probability that the two sides will not be able to fight.

If the commotion here is too big, attract the real owner of this dead underground palace, and we can finish it together.

Think about it,
To be continued...
