Thousands of miles of wild sand, scorching sun.

Yun Mu and Su Wen held hands and walked side by side in the desert, the scorching environment was extremely hot, making it more and more difficult for them to breathe.

It's just that the two of them are in a mood like bathing in a spring breeze at the moment, and they don't feel that the road ahead is difficult, but they faintly hope that this road will never be finished.

"Su asked, how did you come here?"

"My Xuan Ling is about to advance, and I need an extremely cold fire to stimulate the growth of the Xuan Ling and condense the soul of the Xuan Ling, my aunt has searched many places, but she has not found a suitable fire, so she specially brought me here to try my luck. ”

Hearing Su Wen's narration, Yun Mu couldn't help but be a little serious: "The Extreme Cold Fire grows in an extremely cold place, and it is so hot and barren here, I'm afraid it will be difficult to get the Extremely Cold Fire you want early?"

"Hmm. ”

Su Wen nodded, not discouraged, but said: "Auntie said that noon is the genus of fire, and there may be fire left over from ancient times here, whether you can get it depends on your chance." In fact, each of these Twelve Stars Hall contains some opportunities, but after so many years, many opportunities have been taken by predecessors. ”

Yun Mu bowed slightly, and asked again, "How much do you know about the Quartet?"

"I don't know much......"

Su Wen said bluntly: "My aunt told me that this was the last royal city of the human race in ancient times, and it was later sealed into the underground by the powerful with great magical powers, and it became the current underground palace...... In fact, the Twelve Cities are only the entrance to the ruins of the Quartet, and the Twelve Stars Hall is the space gate of the ancient battlefields everywhere, as for what is the situation in the royal city, my aunt is not very clear, only said that it is very dangerous, if you can break in, you can break in, and if you can't break in, you will quit. ”

Su Wen told Yun Mu everything he knew, without the slightest reservation.

After Yun Mu heard it, he sighed in his heart. The former royal city, the ruins of today, the ancient battlefield, and the current desert, this is the history buried by the years.

......

"Brother Mu, what are you doing here?"

"I'm looking for the Miracle Elixir. ”

"Creation Miao Xuan Dan!?"

Hearing Yun Mu's answer, Su Wen couldn't help but be shocked, and then said with relief: "Brother Mu wants to restore Aunt Yun's cultivation, but this Quartet Ruins is not a place of inheritance, will there be such a precious thing?"

"As far as I know, there should be. After all, this was once a royal city, and there should be a lot of good things hidden in the treasure house. ”

In Yun Mu's impression, there must be a Creation Miao Xuan Pill, but he didn't know anything about where and how to get it, so he was still a little apprehensive in his heart.

Su Wen pondered: "But the treasure house of the royal city is in the core of the underground palace, and there are many prohibitions inside, and I have never heard of anyone entering, how sure is Brother Mu?"

Yun Mu smiled bitterly when he heard this: "If it was usual, I naturally wouldn't be sure at all, but this time it was different, the people of the Chen Kingdom came prepared, and the Feng family also intervened...... The predecessors of the Wine Sword Immortal once mentioned to me that Chen Guo and the Feng family came to the core of the underground palace. And, even if I'm not sure, I have to try. ”

Su Wen said solemnly: "Then I'll accompany Brother Mu." ”

"Hmm. ”

Yun Mu shook the other party's hand tightly and walked forward silently.

The two of them chatted while walking, and a scene of sand suddenly rose in front of them, overwhelmingly approaching Yun Mu and Su Wen.

"No! It's a sandstorm. ”

Su Wen was taken aback, his face changed greatly, and he was about to leave, but he was grabbed by Yun Mu.

"Brother Mu, why are you ......?"

"Don't worry, it should be fine. ”

Yun Mu soothed Su Wen and explained, "Think about it, we have been walking for more than half an hour, and the desert here is still boundless, and there is nothing. So I boldly guessed that since the existence of the Twelve Stars Hall was for testing, there would definitely be no mortal situation, and it happened that a sandstorm appeared at this time. Maybe that's the only situation we'll encounter, and maybe those sandstorms will be our chance to clear the level. ”

"Hmm. ”

Su Wen never doubted what Yun Mu said, so he stood quietly beside Yun Mu.

"Buzz~~~"

The wind swept the sand, and the air waves were monstrous.

As the sandstorm approached little by little, the pressure on Yun Mu and Su Wen increased...... The wind was like a tornado, and it was so wild that the two of them were almost suffocated.

"Are you afraid?"

"Don't be afraid, because Brother Mu is by my side. ”

Listening to Su Wen's simple and crisp answer, Yun Mu couldn't help but smile.

"Whew-hu-"

The sand and dust fell, and this moment seemed to be the end of the world, and Yun Mu hugged Su Wen tightly into his arms.

In fact, Yun Mu is also a human being, and he will also feel scared, and sometimes even more timid than others...... He was afraid that he would guess wrong, and that Su Wen would be hurt.

didn't have time to think about it, Yun Mu and Su Wen were already drowning in the darkness.

......

――――――――――――――

In the dark cavern, the two figures gradually stood up, and the surroundings were instantly illuminated.

"It's okay! We're fine!"

Su Wen shouted excitedly, like the innocent little girl from the past: "Brother Mu, you are so smart!"

"Uhh......h

Although many people have praised Yun Mu like this, he felt a little embarrassed when he was suddenly praised by Su Wen.

"Let's go, let's go out and see what this place is, I feel that this place is a little hotter than the desert. ”

"Hmm. ”

The two looked around and saw that there was only one exit, so they walked out along the passage of the cavern.

......

"Plop!

Out of the low-ground hole, the eyes suddenly opened up.

Ten feet underfoot, there are lava gatherings, flowing into the unknown abyss, which is full of terrifying atmosphere.

The air is filled with a thick, pungent smoke that makes people feel unpleasant. In such a harsh environment, ordinary people decided that it would be difficult to survive.

Yun Mu's face was dark, and after some observation, he cautiously climbed along the rocks on the side with Su Wen, looking for the source of the magma.

Although the rock walls are often eroded by magma and filled with fire, the rock here is actually extremely strong, as if it had been tempered with steel.

......

After a few moments, the two of them came to a magma pool, where open flames erupted from time to time, so they stopped.

Unfortunately, the tinder was not found, but Yun Mu and Su Wen found a shining spar at the edge of the pool.

"Brother Mu, what is that!?"

"Yanshi Crystal...... At least 10,000 years of quality!"

Yun Muqiang endured the excitement in his heart, frowned again, and measured back and forth.

[Yan Shi Jing] is a real treasure of heaven and earth, used to refine Xuan Bing or Xuan Bao, it is an indispensable material, especially the tens of thousands of years of quality Yan Shi Crystal, it is the best of the best. A treasure like this, if it is placed in a place like Duobao Pavilion, it is worth millions of Xuanjing, and it has a price, how can Yun Mu not be excited.

It's just that the Yanshi Crystal is at the edge of the magma pool, and it is not easy to get it.

......
