Emperor Tianwu

When Yun Chen and the others arrived, the volcanic eruption had ended. The magma fell on the ground, but it did not melt the ground, because the ground on the third floor was all corroded by magma. There was nothing on this ground that could be corroded by magma, and it became extremely hard.

There were at least eight people who rushed into the sky before, but now there were only three people left on the ground.

The three people looked frightened, and obviously did not expect that the magma would be so terrifying that it directly took the lives of their five companions.

The arrival of Yun Chen and the others made the three people immediately become extremely vigilant, and they all looked at Yun Chen and the others.

If Yun Chen's cultivation was not only in the early stage of the Martial Emperor, and Miao Jialing was only in the late stage of the Throne, they might have left directly.

It is still very easy to escape here, after all, it is not like the outside, where the divine thoughts can flow freely.

These three are all Martial Emperors, one is at the second level of Martial Emperor, and two are at the third level of Martial Emperor. This lineup is naturally not afraid of Yun Chen, but some Martial Emperors who are against the sky can kill Martial Emperors in the middle level when they are in the early stage of Martial Emperor, so these people are a little vigilant.

"Hello, fellow Taoists. I saw you suddenly rushing into the sky before, as if collecting something. I wonder if you can tell me?" Yun Chen clasped his fists and asked very politely.

Seeing that Yun Chen was quite polite, the three of them were relieved.

As long as Yun Chen didn't come to cause trouble for them, it would be fine.

As for what they collected, there was no need to hide it.

At that moment, the cultivator of the second level of Martial Emperor said: "It is Fire Marrow Crystal. Fire Marrow Crystal is a ninth-level material. Such good things are generally not found outside!"

"Fire Marrow Crystal." Hearing this, Yun Chen was overjoyed.

He knew this thing. It was a treasure that could promote the Heaven and Earth Alien Fire!

He now has two kinds of flames, Purple Killing Fire and Blue Enchantress.

Blue Enchantress has already given birth to a fire spirit, and it is already a spiritual flame. It is basically impossible to go further.

However, the level of Purple Evil Fire is still very low. If he can get some Fire Marrow Crystals, he may be able to give birth to a fire spirit in Purple Evil Fire. In this way, it will be much easier for him to refine pills in the future.

In addition, Fire Marrow Crystals can also refine magic weapons with fire attributes. Outside, the price of a Fire Marrow Crystal is more than five million high-grade spirit stones.

With such a high price, it is no wonder that some people risk their lives to collect Fire Marrow Crystals.

"Can you sell me your Fire Marrow Crystals?" Yun Chen asked immediately.

He had wasted too much time looking for the Swallowing Heaven Fruit on the second floor, so he didn't want to waste time on the third floor. He had to go to the fourth floor as soon as possible.

Therefore, if he could buy the Fire Marrow Crystals of these three people, he would not mind buying them directly.

"You want to buy Fire Marrow Crystals?"

"Yes!" Yun Chen nodded.

"Do you know that a Fire Marrow Crystal requires at least five million high-grade spirit stones?" The cultivator of the second level of the Martial Emperor asked again.

Yun Chen naturally knew this, and nodded and said, "Yes, but I don't have that many spirit stones on me. I am a seventh-grade Dan King, and I have a lot of elixirs on me. If you need elixirs, I can use them to exchange for Fire Marrow Crystals."

It is no longer a secret that he is a seventh-grade Dan King, and there is no need to hide it.

"You are a seventh-grade Dan King?" The three asked in surprise.

"Yes!"

"Well, I need Huixuan Dan. For a bottle of Huixuan Dan, I will give you a Fire Marrow Crystal." Zhang Zetao said, looking at Yun Chen nervously.

If Yun Chen can't take out Huixuan Dan, he won't take out the Fire Marrow Crystal.

If the other party is not a Dan King, he won't even trade with the other party.

The reason why he chose to trade with the other party is that he really needs Huixuan Dan, and secondly, he wants to make friends with Yun Chen.

Such a young seventh-grade Dan King has a promising future.

Knowing an alchemist, I don't know how much trouble he will save in the future.

"Sure!" The Huixuan Pill was only a sixth-grade pill, and Yun Chen happened to have more than one bottle, so he immediately said, "I have six bottles of Huixuan Pills here!"

While speaking, he had already taken out six bottles of Huixuan Pills and opened one of them so that the divine senses of several people could scan it.

After Zhang Zetao's divine sense scanned it as a real Huixuan Pill, he immediately became a little excited. Without thinking, he took out six Fire Marrow Crystals and handed them to Yun Chen: "I'll trade!"

The two of them handed the things to each other and then put them away.

"I need a bone-breaking pill..."

"I want a blood pill..."

The remaining two also traded with Yun Chen, and soon Yun Chen collected twenty Fire Marrow Crystals.

Twenty Fire Marrow Crystals should allow the Purple Evil Fire to advance, which made Yun Chen very satisfied.

At this time, a violent roar came from not far away. Obviously, another volcanic eruption.

Zhang Zetao and the other two looked at each other and rushed over there, while Yun Chen was ready to go straight to the fourth floor.

"Oh no, it's a terrestrial dragon!"

Just then, Zhang Zetao's exclamation suddenly came from not far away.

"Roar..."

A roar came, and Yun Chen's eyes immediately looked over there.
