Looking at the ore in his hand, it radiated a scorching aura, with starlight twinkling on its surface.

It was undoubtedly Nine Flame Star Crystal.

Zhang Yuhe couldn't help but rejoice in his heart.

Nine Flame Star Crystal is the core material for refining a mid-grade Immortal Extermination Cannon.

Although many other materials are needed to assist, as long as there is Nine Flame Star Crystal.

Other materials are easy to collect.

Now the only problem is that he doesn't have the blueprints for refining a mid-grade Immortal Extermination Cannon.

But there's no rush, the blueprints will be found sooner or later.

The Nine Flame Star Crystal in his hand is quite large, enough to refine at least three mid-grade Immortal Extermination Cannons.

Of course.

This is only if all of them are successfully refined.

The Immortal Extermination Cannon refining process is extremely complex, and the failure rate is very high.

But that's for other people.

For him, there is no such thing as failure.

Looking at the Nine Flame Star Crystal in his hand.

Zhang Yuhe considered where to find the blueprints for refining a mid-grade Spirit Immortal Extermination Cannon.

The Heavenly Palace Market is vast, with many large merchants from across the seas.

They should be able to buy blueprints here, right?

"Forget it, let's get a few low-grade Immortal Extermination Cannons to play with first, and then go to the market later."

Zhang Yuhe got up and went to the refining room next door.

With a wave of his right hand, a huge four-legged square cauldron appeared before him.

As various materials were continuously put into the cauldron.

Zhang Yuhe pinched the magic formula, and scorching flames ignited from under the cauldron.

The Immortal Extermination Cannon is composed of several parts.

That is to say, he needs to refine several parts at the same time, and then fuse them together.

If there is a problem with any part.

The entire refining result will fail.

Zhang Yuhe was not worried about this.

He watched the changes in the cauldron while silently comprehending the laws of power.

Half a year later.

A mini cannon appeared in his hand.

Zhang Yuhe cast a magic formula.

The cannon instantly grew larger, turning into a majestic Immortal Extermination Cannon.

"Not bad, not bad."

Looking at the Immortal Extermination Cannon in front of him, Zhang Yuhe was quite happy.

Although it is only a low-grade Immortal Extermination Cannon, it is very difficult to deal with Chaos Beasts in the Golden Immortal Realm.

But it's better than nothing.

After putting away the Immortal Extermination Cannon, Zhang Yuhe continued to return to the refining room.

Two years later.

Five low-grade Immortal Extermination Cannons were all refined.

He fixed all these Immortal Extermination Cannons on the flying boat.

When facing the enemy in the future.

He doesn't need to wave the Nine Heavens Flying Spirit Staff to knock on other people's heads anymore.

Just use a law confinement directly, and then fire the cannon.

Although the low-grade Immortal Extermination Cannon is a bit lacking.

As long as the Immortal Body has not been cultivated to the Minor Accomplishment Realm.

Even if facing a Golden Immortal cultivator, five cannons firing at the same time can still kill him.

Zhang Yuhe did not test the power of these Immortal Extermination Cannons.

Every time this thing fires a cannon, it needs to consume a Chaos Beast crystal core.

There is no need to waste it.

He turned around and returned to the cave, preparing to pack up and go to the market.

Suddenly, his expression changed.

A Immortal Transmission Mirror appeared in his hand.

After casting a magic formula and seeing the message content on it, he couldn't help but become thoughtful.

"Is the Nangong Immortal Clan ready with the Lightning Absorption Pillars?"

Just now, Nangong Youxi sent a message.

Asking him to meet at the Heavenly Palace Hall in the market when he has time to discuss the arrangement of the Tribulation Platform.

"Let's go take a look, solve the matter as soon as possible, and get the Nine Brilliance Spirit Immortal Pill."

Thinking of this, Zhang Yuhe turned into a stream of light and quickly flew towards the center of the market.

After a while.

A palace suspended in mid-air appeared before him.

Heavenly Palace Hall.

This is the core of the Nangong Immortal Clan in the market.

Nangong Youxi personally greeted him outside the hall.

The two entered the hall.

Nangong Youxi directly said.

"According to Zhang Daoyou's instructions, we have prepared all 10081 Lightning Absorption Pillars."

"I wonder if Daoyou has time now? Come with me to arrange the Tribulation Platform?"

"Okay."

Zhang Yuhe nodded in response.

He also wanted to solve the matter as soon as possible, and then get the Nine Brilliance Spirit Immortal Pill.

According to the previous agreement.

After the Tribulation Platform is arranged, the Nangong Immortal Clan will hand over the Nine Brilliance Spirit Immortal Pill to him.

"Then shall we set off now?"

"Good."

Nangong Youxi waved his hand.

A huge flying boat hovered in mid-air.

The two stepped onto the flying boat and quickly flew into the distance.

Nangong Youxi said.

"According to Old Ancestor Tianming's instructions, the Tribulation Platform will be arranged near Heavenly Palace Island."

"It will take about half a month to fly from here."

Zhang Yuhe nodded.

The flying boat quickly Pass the sea.

On the way, you can occasionally see the figures of cultivators flying by.

Compared to the Ji'an Sea Area.

The Heavenly Palace Sea Area is much more prosperous.

The atmosphere of cultivation here is stronger, and there are more cultivators.

Occasionally, you can also see Golden Immortal cultivators on the road.

This is completely unimaginable in the Ji'an Sea Area.

You must know.

In the Ji'an Sea Area, every Golden Immortal cultivator is an existence who claims to be the ancestor of the clan.

It is easy to see no one.

Half a month later.

The flying boat landed on a deserted island.

In the center of the deserted island, there is a huge platform.

A team of blue-clothed disciples saw the two arrive and shouted respectfully in unison.

"Greetings, Old Ancestor Youxi."

Nangong Youxi nodded in response, then turned to Zhang Yuhe and asked.

"What does Daoyou think of this place? Can the Tribulation Platform be arranged?"
