Infinite Evolution

War Soul City was the first ghost city that Chu Xun saw when he came to Yincao Difu.

Unlike the underworld that Chu Xun once imagined, the difference between this place and the Yang Realm is actually not that big, except that there is no sun in the sky, only a piece of gray, and there is that weird fog everywhere. Plants, stones, and all kinds of yin beasts and worms formed by condensing yin energy can be said to be just a different kind of big world.

And the battle spirit city in front of Chu Xun looks very similar to the ancient Chinese city in terms of size and shape. Not only the city walls are tall, but there are also some guards in armor, holding sharp knives and weapons in front of the wide open city gate. They are guarding, checking and collecting taxes on "people" coming and going.

If it weren't for the fact that these people's bodies were somewhat illusory and blurred, and there were no shadows at all, Chu Xun would even think that he had traveled to ancient times.

Approaching the city gate, Chu Xun found that those ghosts would deliver some gray crystals similar to crystal nuclei when they entered the city of War Soul, and then they would be released by the gate guards.

Obviously, that should be some kind of currency that circulates in the underworld.

However, he is not from the underworld, nor does he have this kind of currency. How does this allow him to pass through the Battle Soul City and enter the front line of Battle Soul Mountain to find the battle spirit transformed by Zhao Guobin?

Thinking of this, Chu Xun couldn't help but get a headache.

It's impossible to call over!

"My lord, please come in!"

However, what surprised Chu Xun was that when it was his turn, not only did the guards not trouble him, but they all showed a look of horror, stepped back a few steps, and opened the door for him.

"Why can I enter the city without paying, but they need it?" Looking at the fear and reverence of the guards, Chu Xun asked with a slight twitch in his heart.

"My lord, don't make fun of us!"

"You are the power to bring souls into the underworld, how dare we embarrass you?"

"My lord, please enter the city again. Presumably you have come to Battle Soul City this time to prepare to go to the front line of Battle Soul Mountain to hunt and refine ghost generals. I wish you a good harvest this time!"

"Yeah, there's been quite a lot of action in the Death God Realm recently. It's said that many powerful ghosts have come. With your ability, you can definitely find the right one!"

Hearing Chu Xun's words, the guards all changed their expressions, and then laughed a few times, and said with a flattering look.

"It seems that it is not an easy task for a living soul to enter the underworld..."

Looking at the cautious appearance of these guards, and thinking of the bull-headed and horse-faced attitude before, Chu Xun nodded thoughtfully, then ignored the guards, and directly entered the Battle Soul City.

To Chu Xun's surprise, the Battle Soul City was surprisingly lively, not at all as eerie as he had imagined. There are ghosts, real or virtual, wandering or shopping everywhere, and there are many shops and vendors on both sides of the road. It looks like a bustling human city.

In addition, Chu Xun also found that the more solid the bodies of these ghosts, the stronger the aura they emitted. Obviously, this should also be a representative of the strength of ghosts, but even if there are ghosts all over the street, he has never seen any existence that is as condensed as a solid entity like a bull's head and horse face.

It seems that the strength and status of this bull-headed horse-face are far from being as simple as what they said...

Thinking of this, Chu Xun narrowed his eyes slightly, and then continued to walk forward. This Battle Soul City is equivalent to the fortress on the front line. As long as he passes through here, he can enter the war zone of Battle Soul Mountain and look for Zhao Guobin.

"My lord, please stay!"

However, when Chu Xun was shuttling through the War Soul City and walking towards the War Soul Mountain, suddenly a few more cohesive ghosts stopped in front of him and said respectfully.

The strength of these ghosts is obviously good. Although they are not as cohesive as the bull's head and horse face, they are far better than most of the ghosts on the street. And judging from the strong aura they exude, even if they are placed on the end of the world, they are probably already equivalent to the 8th-order powerhouse!

"What do you want to do?"

Chu Xun was still busy rescuing Zhao Guobin and returning to the Yang Realm to meet the battle of the Sea Clan. There was no time to waste. So seeing these ghosts blocking the way, Chu Xun frowned and asked impatiently.

"My lord, please calm down!"

Seeing that Chu Xun seemed to be angry, a hint of horror appeared on the somewhat illusory faces of those ghosts, and then the leader hurriedly said: "We stopped you to make a deal with you!"

"trade?"

Hearing the words of those ghosts, Chu Xun frowned even tighter. He couldn't figure out what deal he could make with these ghosts.

"Your Excellency came to Zhanhun City, presumably to go to Zhanhun Mountain to hunt those ghosts?" After carefully looking at Chu Xun, the leader Yinhun said again: "There are a lot of Xuxu on the front line of Zhanhun Mountain. When the time comes, my lord There will be many battles. Our request is very simple, that is to follow the adults, devour those who the adults look down on, and then beheaded."

"Joke, why should I bring you?"

Hearing the ghost's words, Chu Xun sneered suddenly, and said, "Taking you with me is equivalent to bringing a few burdens on me, not to mention, I don't think you can bring me any benefits."

"My lord, calm down, please listen to my little one." Looking at Chu Xun's increasingly cold eyes, the leading ghost hesitated for a moment, and then said: "We are different from adults, adults are living souls, and we are ghosts, so Although our strength is not as good as yours, you can barely keep up with your steps."

Speaking of this, the ghost seemed to have made some decision, and then said in a deep voice: "As for the benefits, the few of us are only one step away from breaking through the 'ghost spirit', we can swear in the name of Emperor Fengdu, as long as the Lord allows us to devour it." Xu, break through this last step, be promoted to ghost spirit, and stay in the underworld forever, then I am willing to offer half of my soul crystal!"

"What is a soul crystal?"

As for some information about the Great Thousand World, Chu Xun is a real two hundred and five, and he doesn't know anything, so naturally he doesn't know the function of the soul crystal.

Just looking at the seriousness of these ghosts, this soul crystal seems to be very precious?

But no matter how precious it is, it is not as important as the task. Thinking that the sea clan war may start at any time, but he is trapped in this damn underworld, Chu Xun feels agitated and ready to refuse.

"Host, promise them!"

However, at this moment, the voice of the system suddenly rang in Chu Xun's mind: "Soul crystals are a unique product of the Yin world, and only ghosts above the ghost realm can be condensed. Soul crystals can not only strengthen the human soul , can strengthen the spirituality of the weapon. If the host can get enough soul crystals and inject them into the tiger soul knife, then you may use the power of the soul crystals to completely control the white tiger's fierce spirit in the tiger soul knife. How terrible it is, it can only be used by you!"

Speaking of this, the voice of the system also became a little excited: "More importantly, with the support of enough soul crystals, the white tiger's fierce soul can even condense its own Yin body like these Yin spirits, and use another kind of recovery method. At that time, among the four spirits, the host will already have Xuanwu and Baihu!"

"It's still useful?"

Hearing the system's words, Chu Xun's heart skipped a beat, and the words of refusal that were about to blurt out also changed: "Okay, since you are willing to pay such a price, then I will fulfill you!"

The evil spirit of the white tiger has always been a hidden danger in his heart. Although up to now, the evil spirit of the white tiger has faintly felt sad once or twice, but these two times have put Chu Xun in great danger. More importantly, as the tiger soul knife devours more and more blood and souls, the strength of the white tiger's fierce soul will gradually recover. If it returns to its peak state, even the current Chu Xun does not have much confidence in being able to do so. Take it under control!

After all, even Chi You, the unrivaled powerhouse who created the Tiger Soul Knife at the beginning, was finally backlashed by the Tiger Soul Knife, and fell completely, leaving no bones left!

"Thank you for your grace!"

Hearing that Chu Xun agreed to their request, the ghosts were overjoyed and fell to the ground together.

Their "yin life" is not long. If they can't break through this last step, condense the yin energy of heaven and earth into soul crystals, and be promoted to "ghost spirits", then they will be forced to reincarnate, and years of hard work will be wasted.

That's why they would rather pay the heavy price of being weak for a hundred years after the breakthrough, and follow Chu Xun to enter the Battle Soul Mountain and fight for it!

After all, this is a great power who can enter the underworld with a living soul, following him, there will be no danger, right? Such a good opportunity, they can't miss it!
