Three days later, the spirit crab came back, and he said to Ling Feng: "Ling Feng, stop practicing now, do me a favor!"

Ling Feng opened his eyes, looked at the spirit crab and asked, "What can I help you with?"

"All the construction of the Sky City is almost completed. Now only the defensive formations and the main attack guns are left. It's time for you and Ziyue to take action!"

The spirit crab floated in front of Ling Feng, blowing bubbles. It knew Ling Feng's skill in carving formation patterns was superb, and it also knew that Nangong Ziyue's skill in refining weapons was superb.

So now the remaining two items can only be left to Ling Feng and Nangong Ziyue.

Ling Crab is a crab that likes to pursue perfection, so it wants Ling Feng and Nangong Ziyue to take action.

Although they had grabbed a lot of war boats in the ancient battlefield, the main guns on those war boats felt that the spirit crabs were too weak.

So now Ling Crab wants Ling Feng and Nangong Ziyue to join forces to refine some powerful main guns.

At least the power of those main guns can reach the nine-star level.

"good!"

Ling Feng nodded. Ling Crab had told him before about how awesome this city in the sky was, and he had also seen the conceptual drawings Ling Crab had made before.

Before, he thought that the spirit crab could not build such a huge thing, but now the spirit crab is almost successful.

Ling Feng immediately found Nangong Ziyue.

"Brother Qin Xiao, what's the matter?"

Although her training was interrupted by Ling Feng, Nangong Ziyue was still very happy after seeing Ling Feng.

"Brother Crab!"

After Nangong Ziyue saw the spirit crab, she immediately walked up to the spirit crab and hugged the spirit crab.

The spirit crab allowed Nangong Ziyue to hold it. It knew that it was now asking Nangong Ziyue for help, so it did not dare to resist.

"Ziyue, Ling Crab's Sky City is almost completed. Now we need to work together to refine something. I hope you can help!"

Ling Feng also knew that although Nangong Ziyue was a weapon-refining genius from a family of weapon-refining masters, he also knew that Nangong Ziyue didn't like weapon-refining in her heart. This girl liked fighting and the feeling of fighting.

So when he told Nangong Ziyue about this matter, he seemed very tactful.

"Yeah?

No problem, Brother Qin Xiao, if you want my help in the future, don’t be so polite. If you are too polite to me, it will appear to be indifferent!"

Nangong Ziyue spoke and looked at Ling Feng with some resentment.

"Okay, I get it!"

Lingfeng reached out and touched Nangong Ziyue's head, and then led Nangong Ziyue and Ling Crab to the core area of ​​Sky City.

This core area is the construction center of the Sky City. Previously, only spirit crabs could enter.

Now Ling Crab is here with Ling Feng and Nangong Ziyue.

When Ling Feng and Nangong Ziyue arrived at the construction center, they found that there were many crabs busy here. In addition to these crabs, Ling Feng also discovered the construction puppet that he had given to the spirit crabs before.

At this moment, in the construction center, there are some giant crabs that are over a hundred meters in size. Those giant crabs have huge awls on their pincers. These crabs have different shapes, but they have a clear division of labor.

Some are specialized in screening materials, some are responsible for handling, and some are responsible for hammering and forging.

Seeing this scene before him, Ling Feng finally understood why the Spirit Crab was able to almost complete the construction of the Sky City in such a short period of time.

“So many crabs!”

After Nangong Ziyue saw the scene of the construction center, she seemed very shocked. She subconsciously licked her lips.

"Ziyue, these crabs are inedible!"

Ling Crab also saw Nangong Ziyue licking her lips, and immediately reminded Nangong Ziyue.

The spirit crab loves Nangong Ziye in its heart, and it doesn't want Nangong Ziyue to have any wrong ideas about these crabs.

Nangong Ziyue lowered her head and looked at the spirit crabs in her arms, and said with a smile: "Don't worry, I won't eat them!"

After saying that, Nangong Ziyue let go of the spirit crab.

Ling Feng asked Ling Crab, "Tell me, how can we help?"

Ling Crab said: "You guys help me refine the source power furnace first. The previous source power furnace of Yinquezhou cannot drive the current Sky City. It can only be used as an emergency energy source. We must

We must create a more powerful Source Power Furnace!"

While the spirit crab was talking, it spit out a bubble, and inside the bubble, there was a structural diagram of a source power furnace.

When Ling Feng saw the structural diagram of the Source Power Furnace, his face sank slightly, and then he said: "You guy, you have learned to lie now. You told me before that you just didn't have the defensive formations and offensive weapons ready. Now

Did you build another Source Power Furnace for me?"

Although Ling Feng was not a professional refining master, he could see that refining this source of power furnace was definitely a big project.

"I'm not lying. This Yuanli furnace is very simple. Don't be scared by its appearance!"

The spirit crab looked at Ling Feng and Nangong Ziyue and kept spitting bubbles.

Ling Feng glanced at Nangong Ziyue.

Nangong Ziyue knew what Ling Feng meant. She nodded and said, "This Source Power Furnace looks so interesting. Brother Qin Xiao, let's do it. After the sky city is built, we will also be the beneficiaries!"

"good!"

Lingfeng nodded, and then under the guidance of the spirit crab, he began to refine the source power furnace.

Ten days later, Ling Feng and Nangong Ziyue began to refine a Source Power Furnace.

"Perfect!"

Seeing the source power furnace refined by Ling Feng and Nangong Ziyue, the spirit crab couldn't help but admire it.

This Source Power Furnace has not reached the level of a ninth-grade magic weapon, but it is close to the ultimate level of an eighth-grade magic weapon.

Originally, Ling Feng thought it would take a long time to refine the Source Power Furnace, but after starting to refine it, he discovered that the Source Power Furnace was really not that difficult to refine as Ling Crab said.

.

Because before this, Ling Feng thought that he and Nangong Ziyue would complete everything.

But during the refining process, other crabs also join in. Some crabs can temper it, and some crabs can carve patterns.

This also reduced the workload of Ling Feng and Nangong Ziyue a lot.

According to Ling Crab's idea, this city in the sky needs a total of eight such source power furnaces.

Moreover, this Source Power Furnace was also tinkered with by the Spirit Crab based on its own experience and based on the basic ideas of its Crab Clan predecessors.

Now that they have fallen into the trap, Ling Feng and Nangong Ziyue have no choice but to continue refining.

But this time, they plan to refine the remaining seven source power furnaces at once.

Although they had to perform the same step seven times in a short period of time, with the help of Ling Feng's soul liquid and body tempering liquid, this was not a problem for him and Nangong Ziyue.

When refining the first Source Power Furnace, Ling Feng and Nangong Ziyue were not familiar with many processes, so they had to slow down.

But when they successfully refined a Source Power Furnace, they knew the entire refining process by heart.
Chapter completed!
