As for what Gu Yuchen's true thoughts were, Lu Jin didn't know and didn't want to know.

After retracting the formation and the wooden house, the two set off again.

Lu Jin didn't say more than ten words to Gu Yuchen in the past few days, and he was only in a hurry.

During the period, I took another break, and there were no big twists and turns.

Just counting the time to hurry, the two walked for six days, faster than expected.

Lu Jin and Gu Yuchen arrived at the market closest to Qiyang Mountain.

This market is far less large than Wenxianfang City, only a quarter of Wenxianfang City.

But although the sparrow is small, it has all kinds of organs.

I found an inn and stayed for a day, regained my spirits, and left the inn with Gu Yuchen the next day.

The mountain of Qiyang is rich in products, the south of the mountain produces red gold, the north of the mountain produces platinum, the aura gathers, and there are many strange beasts entrenched in this mountain.

In his dream, the Lu Shu that Gu Yuchen dreamed of was a kind of alien beast, and Lu Shu was just one of them.

There is not just one mountain, there are other mountains and unknown mountains around it, but the real mountain is the largest in the core.

Lu Jin sat on an unnamed mountain bag in front of Qiyang Mountain, looking at the Qiyang Mountain in front of him.

Although there is only one mountain in Qiyang, it is unexpectedly large, and this mountain is larger than any single mountain in the Yuansheng Sect and the Yuansheng Immortal Sect that Lu Jin has seen.

Usually I walk in a straight line in the sky, and it will be much faster, so I don't feel how big these mountains are, but when I really face this mountain, I find how small people are.

Compared with Qiyang Mountain, this small mountain bag is the gap between babies and adults.

Lu Jin and Gu Yuchen were looking for earth and heavy wood, so naturally they couldn't fly around from the sky like they came.

Speaking of earth heavy wood, Lu Jin remembered the wood fire that the Origin Sect Master gave her before, and he didn't know what the connection was.

If it is related to the five elements, it is not right, the earth is gold, but the earth is heavy wood is the soil with strong vitality.

Lu Jin couldn't figure it out, she asked Gu Yuchen, "Gu Daoyou, have you heard of the fire in the wood?"

"Wood fire is a kind of Danhuo, a medium-grade spiritual fire, which is relatively rare. Gu Yuchen explained succinctly.

In the same way, there are grades of fire, but compared to the grades of various treasures, the grades of fire are not so complicated.

There are only four grades: lower, middle, upper and extreme.

Monks who usually have a fire spirit root can control the fire during the qi refining period, and this fire is just an ordinary ordinary fire, and it is not a product.

If a monk with a fire spirit root cultivates some fire-based exercises, the level of fire will also increase.

But there are other spiritual fires, such as this wood fire.

After Gu Yuchen's science popularization, Lu Jin learned that the fire in this wood belongs to the second type of fire, which is artificially extracted and refined, and has the same properties as the heavy earth wood refined by Gu Yuchen.

But there is a third kind of fire, the spiritual fire naturally bred between heaven and earth, this kind of spiritual fire can be encountered but not sought, as long as it is found, it is also the lowest grade spiritual fire.

It's just that this kind of spiritual fire is difficult to obtain, and the places where they are located are all in extremely high temperatures.

If it weren't for the cultivators who cultivated the fire attribute exercises, if others wanted to take the spiritual fire, it would undoubtedly be the old birthday star who ate arsenic—he was tired of it.

But there is always an exception to everything, such as the well-known water overcomes fire, but when the fire is strong enough, the fire will instead burn the water into water vapor.

In the same way, when a monk's cultivation or physical body reaches a certain strength and can resist the erosion of fire, even if it is not a fire spirit root, he can also use the spiritual fire for his own use.

The people of the Yuansheng Immortal Sect only practice the wood exercises, so ordinary monks are simple, and they all draw the earth fire to alchemy.

But when it reaches the Yuan Infant Stage, the elders of the Yuansheng Immortal Sect will go to find the spiritual fire between heaven and earth to use for alchemy, and when they reach that level, they can basically ignore the burning of the fire and take fire from the fire.

Lu Jin learned new knowledge from Gu Yuchen's mouth, and when he told Lu Jin this, Gu Yuchen changed his usual personality of few words, and explained it very carefully.

This gave Lu Jin the illusion that he was like a teacher in the village school, and he was his student.

"Thank you. Lu Jin thanked him.

"It's just common sense. Gu Yuchen said.

Lu Jin got up, patted the dust on his hands, and planned to go directly to Qiyang Mountain with Gu Yuchen.

"Wait. Gu Yuchen stopped Lu Jin, he closed his eyes, and his left ear moved slightly.

Seems to hear something.

And Lu Jin also listened carefully to the movements around him, except for the sound of insects and birds and the wind blowing through the leaves, there was no sound.

"It's a beast tide. Gu Yuchen's face was serious and explained: "For some reason, there are many demon beasts in Qiyang Mountain that have been alarmed, and even some demon beasts that originally lived in the center of Qiyang Mountain have also fled out. ”

Good spirits are not bad spirits, in a dream, Lu Jin saw how bumpy Gu Yuchen and 'Lu Jin's trip to Qiyang Mountain was.

I thought it was just a dream, Gu Yuchen had been here many times and it was nothing, it was impossible for her to be so unlucky once, but the fact is that she was indeed unlucky, and there was a nightmare and then a beast tide along the way.

Unlucky things happened to her, and she was unlucky with Gu Yuchen.

Lu Jin said: "Don't be in a hurry at this time, let's go back to the market first and wait for the beast tide to pass." ”

"Good. ”

It was impossible for the two of them to break into the market knowing the danger, and turned around to return to the market the same way, but they heard a "boom", and there was a sound from the position behind them, that is, the direction of Qiyang Mountain.

Immediately, the hill shook slightly, probably far away, so there was not much trembling.

Lu Jin glanced back, and some of the places to the left of Qiyang Mountain were lit up.

From the position of Lu Jin and Gu Yuchen, the scope of the firelight is not large, but the small mountain is far away from Qiyang Mountain, if it is really in place, I am afraid that the battle of this firelight will be much bigger.

Judging from this momentum and the range of firelight, if it wasn't made by someone in the Dan Period, it was someone who had cultivated the fire attribute exercises.

A red shadow rushed out from the firelight, the speed was very fast, from far to near, and the destination was the place where it was necessary to leave the range of Qiyang Mountain, and Lu Jin Gu Yuchen and the two of them were standing at this time.

"Let's go. Lu Jin didn't want to make extraneous branches, so he decided neatly.

Gu Yuchen took out the bamboo sword, and the two turned around and left.

From hearing the sound to Lu Jin's glance back, it was actually just a matter of blink of an eye.
