(Ask for recommendation votes, thank you friends)

He hurriedly and carefully held the Firmament Crystal in his hand, for fear of breaking it.

Ao Cang looked at Qin Cheng with disdain as disdainful as he looked at a bun: "It's a little bit good." Such a little bit of heaven-level material will surprise you like this, and besides, this thing is extremely hard, you look at your careful appearance, you are afraid that it will break. ”

"Huh. Qin Cheng smiled awkwardly, "It's the first time I've seen such a valuable thing, I'm out of shape." ”

"What kind of value is this thing?" Ao Cang rolled his eyes and said, "You have two jades, broken kitchen knives, and some high-end gadgets left by your parents, which are not much more valuable than it." ”

"That's just as well. ”

When Ao Cang said this, Qin Cheng suddenly felt as if he had really become a rich man, but he was not afraid of many good things, so he asked, "What is the use of this Sky Crystal?"

"Of course it's a refining weapon!" Ao Cang raised his eyebrows, "It can directly increase the hardness of the spirit weapon." Don't look at the Firmament Crystal in your hand, it's only a little bit, but it's enough to raise a ground-level spirit weapon to a heaven-level spirit weapon!"

"So powerful!" Qin Cheng exclaimed, "Then I'll quickly integrate him into the Mixed Yuan Dragon Slayer Knife!"

"Stop dreaming. For the first time, the Mixed Yuan Ding Artifact Heart could actively absorb and fuse high-grade refining materials, but after that, it had to be forged by ground-level refining techniques in order to fuse other materials. You don't know anything about refining weapons now, what kind of fusion are you talking about. ”

"It doesn't matter!, I'll go to learn refining weapons after I arrive in Wuji City!" Qin Cheng said excitedly, "A heaven-level spiritual weapon, even if it takes ten years to become a ground-level refiner, it's worth it! Not to mention that I have the assistance of the Great Yan Decision, it will definitely not take ten years." ”

"That's just as well. Then you try it. Ao Cangdao.

Qin Cheng put away the Firmament Crystal, and then he suddenly realized a problem, what about the Spirit Pill?

Thinking of him, he asked: "In the space ring of Sun Jianshuang and several shopkeepers and the entire flying boat, I didn't find the elixir?" According to my guess, I should find the elixir from Sun Jianshuang's space ring or the flying boat." ”

"If you can't find it, you can't find it, even if you prove that the Spirit Pill was made by the Immortal Chamber of Commerce, with your current identity and strength, you can't do anything about it. Ao Cang looked like he didn't care about himself.

"You can't do it now, and you won't have to be able to do it in the future. Qin Cheng retorted and stopped talking, sat cross-legged and closed his eyes to cultivate, and let the flying boat fly along the established route.

I don't know if it was his luck or if this route was safe, along the way, he only encountered a spirit emperor-level spirit beast, but the spirit beast stood far away on the peak and watched the flying boat and did not pounce.

Four days later, in the early morning, when the eastern sky was just revealing a trace of fish belly white, Qin Cheng saw a huge city appear in the eastern sky.

The city is surrounded by towering mountains, but the height of the walls is much higher than those mountains, and from a distance, those mountains seem to be small rockeries.

But Qin Cheng knew that those mountains were all real majestic earth peaks, but that city was too tall.

Endless City is coming!

Qin Cheng received the flying boat into the Liangyi Jade Space, changed his appearance, making his face look more ordinary, only five or six points similar to his original appearance, and then flew towards the giant city with purple gold thunderstorm spirit wings on his shoulder.

It is said that Wangshan runs a horse and runs a dead horse, but Qin Cheng is "tired of flying in Wangcheng" this time.

His speed was almost always maintained at the top speed, but after flying for half an hour, the giant city on the horizon didn't seem to get much bigger.

Qin Cheng just watched the fish white on the eastern horizon turn into flame red, the flame red turned into the morning glow in the sky, the morning glow in the sky turned into the red sun, and the red sun turned into the scorching sun, and the huge city gradually enlarged its figure and became clear.

When the sun came behind him, he finally flew before the giant city.

"Is this Wuji City, so majestic!" Qin Cheng tilted his head in shock, looking at the towering city walls that were more oppressive than the majestic mountains.

The city walls are all made of huge huge rocks, a rock is enough for a million catties, Qin Cheng seems to have seen the scene of the Spirit Emperor carrying the boulders flying all over the sky when this city wall was built ten thousand years ago, and the Ling Emperor carrying the boulders on his shoulders and soaring into the sky!

Today, after 10,000 years, these boulders are covered with traces of time, exuding an aura of long-term recklessness.

"Ahh

Qin Cheng took a breath of cool air.

Building a heaven-level defensive formation on such a huge city is not a small move, it is simply too big.

Not to mention the rarity of Heaven-level Array Mages, just to say how many formation materials would it cost to envelop the entire Infinite City? That was definitely an astronomical amount!

And to ensure the operation of such a huge formation, I am afraid that the daily consumption of spirit crystals will not be less than one million!

The prefecture-level forces are the prefecture-level forces, and their strength is much stronger than the Xuan-level forces, and the disparity between the two is thousands of times more exaggerated than that between the Xuan-level forces and the yellow-level forces.

Qin Cheng said with emotion: "No wonder Wuji Mountain dares to distribute so many spirit crystals to the disciples in the sect, and the disciples of the outer sect can exchange their contribution points for the precious ground-level spirit pill like the Liuding Barrier Breaking Pill!

With emotion in his heart, Qin Cheng flew towards the city gate.

At this time, Qin Cheng found that the gate of this Wuji City was also very interesting, a very large city gate was completely made of a kind of spiritual wood, with a height of more than a hundred zhang, but it was tightly closed, and on both sides of this large city gate, there was a small gate about three zhang high.

These two small doors turned out to be the one on the right and the one on the left, in an orderly manner.

Qin Cheng fell to the ground, and saw a team of guards wearing bright spirit armor and holding various weapons standing at the small gate of the process.

Judging from the aura emanating from the bodies of these guards, they should all have the cultivation of the Spirit King.

On the side of this group of guards, next to the door, close to the city wall, there was a stone table, and behind the stone table sat a middle-aged man in fancy clothes, with his eyes closed as if he was cultivating.

Qin Cheng felt a little strange in his heart, how could there still be people sitting here at this city gate and closing their eyes to recuperate?

Standing and watching for a while, Qin Cheng saw that the people who entered the city had walked directly into the city, so he also stepped forward to enter Wuji City.

"Stop. ”

As soon as Qin Cheng walked to the city gate, the middle-aged man in a fancy dress suddenly opened his eyes and looked at him, and said these two words lazily.

Qin Cheng turned to look at the middle-aged man in a fancy suit.

"This person's cultivation is a six-star Spirit Emperor, you should be careful. Ao Cang Shennian reminded.

"Hmm. I'll pay attention. Qin Cheng thought about the sound, and then with a smile and a hint of doubt, he hugged his fists at the middle-aged man in Chinese clothes and said, "I've seen my seniors, I don't know why my seniors stopped me?"
