"Brother Qin Xiao, let's just refine nine of them at once. If we refine nine of them at once, I can just use a set of family hammering techniques!"

Nangong Ziyue spoke to Ling Feng.

Ling Feng had no objection to Nangong Ziyue's proposal. He asked Ling Crab, "Are your materials enough?"

"Enough, of course it's enough!"

The spirit crab immediately answered that Ling Feng and Nangong Ziyue could refine more source power furnaces, and it was even happier.

Because when this Yuanli furnace is used, some problems may occur.

At that time, if the problem is serious and there is no time to repair, they can replace these new Yuanli furnaces.

"That's okay, let's get started!"

Ling Feng nodded, and then started refining with Nangong Ziyue.

Twenty days later, Ling Feng and Nangong Ziyue refined all nine source power furnaces.

"Tsk, tsk, it's perfect!"

After the spirit crab saw the source power furnace refined by Ling Feng and Nangong Ziyue, it couldn't help but admire it. Its eyes were sparkling, and its expression was like a hungry man seeing a charming woman.

Next, Ling Feng and Nangong Ziyue refined the God-Destroying Cannon together.

The Spirit Crab requires that a total of 108 of these divine cannons be refined.

At that time, these one hundred and eight divine cannons will be installed on the tips of crab legs, as well as crab claws, crab belly, and crab back.

Powerful God-Destroying Cannons will be installed in every corner of the entire Sky City, allowing the Sky City to carry out all-round attacks.

The structure of this God-destroying cannon is not very complicated, so it does not take much time to refine.

In the end, Ling Feng and Nangong Ziyue spent a month refining one hundred and seventeen God-Destroying Cannons.

The extra God-Destroying Cannon should be considered as a spare, because this thing is easily damaged under continuous high-intensity attacks.

After finishing the attack, Ling Feng had to do the rest of the defensive formations himself. Although Nangong Ziyue was good at weapon refining, she was not very accomplished in the inscription technique.

Ling Feng believes that this city in the sky is their mobile fortress, and defense is the most important thing.

Therefore, he also paid special attention when carving the formation pattern.

It took him two months to complete the defensive formation of the Sky City.

He has arranged a total of eighty-one layers of eighth-level peak formations on the Sky City. Once all these formations are activated, Ling Feng believes that even those extraordinary beings will not be able to tear apart the defense of the Sky City.

Those cultivators in the Sky City had received notification from Ling Feng before and thought that Ling Feng would take them away soon.

But they didn't expect that they would stay in this sea of ​​bones for more than four months.

In these four months, Lu Wushuang, Lu Wuji, and Red Snake Girl, after practicing the latest skills taught to them by Ling Feng, have made rapid progress, and their cultivation has reached the state of Tao Ancestor Dzogchen.

.

Nangong Ziyue had to help Ling Feng refine things, so she was delayed for two months. Her cultivation was slightly behind Lu Wuji, Lu Wushuang, and the red snake girl. Her current cultivation

Because he has only reached the perfect state of Taozu.

However, Nangong Ziyue has the help of Lingzhou Cauldron, and it won't take long for her to reach the state of Tao Ancestor Dzogchen.

The cultivation levels of the three Taoist ancestors of Dongdong have also reached the ninth level of the Taoist ancestors.

Yu Jingxian and the disciples of Lingzhi Palace have also reached the ninth level of Dao Ancestor Heaven.

However, the fighting power of Yu Jingxian and the disciples of Lingzhi Palace is still not as good as those of Dongsan Daozu.

Because the disciples of Lingzhi Palace were not good at fighting before, they were only good at planting.

As Lu Wuji and his group's cultivation improved, the strength of Ling Feng and his group also increased with the tide.

More than four months have passed in Cangqiong Island, and in the ancient Tianyuan world, that time has passed more than forty months, which is more than three years.

In the past three years or so, Ling Feng's soul has been in the Ice and Snow Kingdom, continuing to look up those mortal-level skills.

And the half-step spiritual emperors from the four major divine kingdoms also accompanied Ling Feng.

In the past three years or so, the antidote for Zhaohunsan has also been spread by people from the four major divine kingdoms.

The Palace of Hell, an ancient force that has been passed down for millions of years, has finally collapsed.

…

“Finally done!”

In the Sky City, after Ling Feng laid out the last layer of formations, the spirit crab jumped up with excitement, and then it began to debug the Sky City.

Nangong Ziyue, Lu Wushuang, Lu Wuji, and the red snake girl all came to the main control room.

"Rumble..."

The city in the sky, which was originally located in the sea of ​​bones, slowly stood up.

The City in the Sky is built in the shape of a large crab. The length of the crab's body exceeds six thousand meters and its width exceeds four thousand meters. Including the crab's legs, the length exceeds ten thousand meters.

When this big crab stood up, it was more than two thousand meters high.

"Hiss!"

Seeing the Sky City flying up, the gold-eating bone-eating insects that had been constantly attacking the Sky City thought that the iron lump in front of them was trying to escape, so they launched a frantic attack on the iron lump.

The spirit crab immediately activated the formation defense of the Sky City and tested the power of the formation.

"Buzz!"

A layer of formation patterns appeared, immediately blocking the defense of these gold-devouring bone-eating insects.

Those gold-devouring bone-eating insects hit the formation light screen, and the powerful impact only caused faint ripples on the formation light screen.

"This formation is so powerful!"

The spirit crab is very satisfied with the power of this formation.

Then it tests these array light curtains layer by layer.

After testing the formation light curtain, the spirit crab began to test the God-Destroying Cannon.

The shape of the Sky City is a giant crab with a body length of 10,000 meters. From the outside, this giant crab looks dark blue, and the surface color looks like it is forged from bronze.

The same.

Surrounding the two big eyes of the Sky City are two circles of divine cannons, a total of eighteen.

There are a total of one hundred and eight God-destroying cannons in the entire Sky City, but its two eyes occupy only eighteen of them.

The God-Destroying Cannon at the eye position is the most powerful.

At this moment, the big crab's eyes turned and were aimed at the gold-eating bone-eating insects.

"fire!"

The spirit crab was sitting in the control room, and with a command, the crab's two big-eyed eighteen god-destroying cannons fired simultaneously.

"boom!"

A huge sound wave was transmitted from the eighteen God-destroying cannons, and the beam of light did not appear as expected.

Under the action of this huge sound wave, the bodies of those gold-devouring bone-eating insects exploded.

All the gold-devouring bone-eating insects in front of the Sky City were wiped out.
Chapter completed!
