This kind of stone contains an extremely thick solid aura, which can be completely supplied to the cultivators.

In the past, when he first came to Mirage City, Zhang Zichen was still in the second realm of earth immortals, and it took him four or five hours to absorb a small spirit crystal.

At the end of the day, being able to absorb three spirit crystals was already his limit.

And recently, when Zhang Zichen entered the first realm of heavenly immortals, the speed of absorbing spirit crystals accelerated.

A small spirit crystal, it took him less than an hour to absorb it.

This speed surprised Zhang Zichen.

But with the improvement of cultivation, this is a new trouble.

The absorption speed of the spirit crystal accelerated, which also showed that the aura in the spirit crystal was gradually weakening for Zhang Zichen.

If you cultivate further, I am afraid that the aura on this spirit crystal will be as useless as the most ordinary spirit stone.

At that time, I am afraid that only the Spirit Source Stone and the True Source Stone can meet Zhang Zichen's needs.

However, this Spirit Source Stone is already very difficult to obtain, let alone the True Source Stone.

And this is the only difficulty for all monks, so after each monk progresses, he will go around collecting spiritual source stones and true source stones.

But until now, Zhang Zichen has never owned a piece of spirit source and a piece of true source, and at most he only has a few hundred spirit crystals, which he still got by tricks.

In this regard, Zhang Zichen secretly smiled bitterly.

However, before absorbing the spirit crystal, Zhang Zichen still had to do one more thing, and that was to go to the Huangyun Heavenly Book to see how his fire attribute primordial god was.

This fire attribute primordial god, let it stay alone in the Danshu iron coupon to absorb the fire essence, it has been many days, and I don't know what the effect is.

Zhang Zichen only knew that the fire essence in this Huangyun Heavenly Book was already 100% pure, and the fire attribute primordial spirit was among them, and he should be able to get qualitative improvement and leapfrogging.

With this expectation, Zhang Zichen probed his divine sense into the Danshu Iron Coupon.

To Zhang Zichen's surprise, it was pitch black inside the Danshu iron coupon, and as usual, it was as quiet as death.

There is no pure fire essence here, only a primordial spirit, floating alone in the darkness.

As a result, Zhang Zichen felt that he had injected his divine consciousness into the primordial spirit.

In an instant, Zhang Zichen felt that his body was filled with powerful fire attribute power.

The flames seemed to erupt from him, and Zhang Zichen could feel the flames burning all over his body, but he was just not afraid of the flames.

Zhang Zichen stayed in the earth fire furnace of Alchemy Island for three whole months, and this Danshu iron coupon also absorbed the fire essence for three whole months and purified it.

But I didn't expect that in just ten days, all the fire essence in it was absorbed by the Yuan Shen.

This made Zhang Zichen feel very surprised.

I don't know what the power of the fire attribute primordial god is like now?

With Zhang Zichen's thoughts, Zhang Zichen controlled the fire attribute primordial spirit, walked out of the Danshu iron coupon, and entered the dantian.

In order to test the power of this fire attribute primordial god, Zhang Zichen controlled him to merge with his own body.

In an instant, Zhang Zichen opened his eyes, his whole body was hot, and streams of red flames burst out from all directions of his body.

It's just that what Zhang Zichen didn't notice was that in the center of his eyebrows, a fiery red dot was still blurry.

If Zhang Zichen noticed this, he would know that the fire essence absorbed by his fire attribute primordial spirit was still too different, and it was far from the standard.

Otherwise, the fiery red dot in the center of Zhang Zichen's eyebrows will be transformed into a fire character, and this fire character will gradually become clear and abnormal from the blur at the beginning.

But it doesn't matter, the current fire attribute primordial god has absorbed a lot of fire essence, and it is much stronger than before.

Zhang Zichen waved his hand, and a flame would erupt from his hand, and he could destroy the entire room with a random thought.

However, Zhang Zichen is not a stupid person, and if he burns down the room, he will definitely make others unwilling.

Zhang Zichen is now under the fence, so he naturally has to abide by other rules.

However, Zhang Zichen especially wanted to test how strong his fire attribute power was, and what Zhang Zichen wanted to see most was the combination of the fire attribute physique in his body and the top-grade immortal Yin Yang God Divine Flame Spear, how much power would this produce, which made Zhang Zichen look forward to it again and again.

But this is on the treasure ship, after all, it is someone else's place, Zhang Zichen has treasures, and he can't leak them.

In this matter, Zhang Zichen has already told Scarlet Yue, Ding Yao, Long Fei and others a thousand times, telling them to keep a low profile.

According to Wang Xiyue, even Elder Wang Yi in the middle stage of the Great Luo Golden Immortal only used a low-grade immortal weapon.

If the real person knew that each of them had a high-grade immortal weapon on them, they were afraid that after being jealous, it would cause unnecessary trouble.

Whether it is an elixir or a high-grade immortal weapon, this is quite powerful for the attraction of a monk.

Everything has to be careful and cautious in order to live safely.

For this reason, Zhang Zichen dismissed the idea of testing the combination of the fire attribute primordial god and the yin-yang god musket.

This test will have an opportunity in the future, and there is no need to rush it.

So, Zhang Zichen controlled the fire attribute primordial gods, retreated to the dantian, and stayed quietly with the other primordial gods.

In Huang Yuntian's book, there was no fire essence left, and Zhang Zichen began to think, how should he get the fire essence?

Do you want to go to the Kunwu Volcano of the Jin clan in Huozhou, or return to Penglai Xiandao?

However, Zhang Zichen will go to these two places sooner or later.

If you go to Kunwu Volcano, you can absorb the true fire of the sun, and if you go to Penglai Immortal Island, you can absorb the true fire of Taiyin.

The combination of these two flames is even more powerful and indispensable.

But for now, it is better to wait until the affairs of the Jiang family and the Wang family are dealt with, and then make a conclusion.

Thinking of this, Zhang Zichen took a deep breath and glanced at the room, everything was as usual, so he took a spirit crystal in each hand, closed his eyes and meditated, and began to absorb the spiritual energy in the spirit crystal to enhance his strength.

From the royal family's headquarters to Tianwang City, there is a journey of 130,000 kilometers, and it takes seven and a half days for the treasure ship to fly.

In the past seven and a half days, Zhang Zichen and several of them have been able to quietly digest the experience they have gained during this time.

Outside the room, the sky was high in the sky, and it was dark in the blink of an eye.

In the night sky, the drizzle is getting heavier, crackling on the hull of the ship, and the sound is extremely beautiful, like a beautiful song of nature, so that everyone's sleep is more peaceful.

In the blink of an eye, it was seven days later.

The mirage city in the heavy rain is ancient and solemn, this ancient city has raised millions of ordinary people, and there are also hundreds of thousands of monks from all over the world who have lived for a long time again.

But all of these people are not as mysterious as the Zhuge clan.

The ancestor of the ancient Zhuge clan, it is said that he was once just a fisherman by the sea, and one day he was fishing, and he encountered a big giant whale crossing the catastrophe and impacting the realm of Da Luo Jin Xian.
