---------------

On the seventh day after the World Summit, news about the Angel Empire and the opening of Heaven in the Sky spread across the world, reaching both the Grand Line and beyond. 

The excitement was so immense that it temporarily overshadowed the World Summit itself. It was announced that Heaven would open after the World Summit, leading to a massive influx of ships from all over the world to Dengtian Island, which is made up of three layers: inner, outer, and upper.

Initially, it was planned for the Sky Paradise to officially open on the second day of the World Summit. However, due to unexpected circumstances, the opening was postponed by one week. As a result, nearly a million people gathered on Dengtian Island, eagerly awaiting the opening of Heaven in the Sky.

Among the visitors were vacationing Marine officers, pirates from the Grand Line and New World, royal nobles from various countries, and even kings who stayed after the World Summit, accompanied by their families.

Some Celestial Dragons had already entered Sky Paradise. However, since it had not officially opened yet, most of the facilities were still preparing to welcome the large number of guests.

Above the first layer of island clouds, Arthur floated in midair, addressing the Sky Island officials and reporters from various newspapers around the world. 

"Today, the Heaven in the Sky created by the Angel Empire will open to the world!" 

As Arthur finished his statement, the live broadcast to Dengtian Island filled the air with cheers from the tourists watching and waiting. 

They could hardly wait to exchange their money for an unforgettable experience. The beauty, entertainment, and luxury offered here exceeded anything even the royal families of any nation could provide. Here, everyone could experience joy that even kings might not have encountered.

After Arthur spoke, he vanished into the air. He still had important matters to attend to.

The Heaven in the Sky had changed significantly since before. After relocating Fish-Man Island here, Arthur looked at the empty island and Fish-Man Island, believing that the two could benefit from being together.

While Jessica was present, Arthur took her to gather countless floating clouds and deserted island clouds. With Jessica's powers, these flowing clouds and small islands transformed into a vast solid island cloud. These island clouds served one purpose: reinforcement!

After relocating Fish-Man Island, the circular sea of Apayado and the island clouds formed a structure beneath the Cloud River.

Because they were located in the Calm Belt, these clouds remained mostly stationary, as if fixed in the sky. Additionally, Arthur used metal to create a framework within these island clouds. Thanks to the electromagnetic field, the Cloud River and seabed of these island clouds became as stable as Mount Tai.

Arthur wanted to incorporate the mermaids into the Heaven in the Sky experience. So he decided to build a new mermaid-themed island, a Mermaid Paradise!

To achieve this, part of the ring sea of Apayado and some of the Cloud River was filled with blue seawater. Because the blue ocean was heavier, it was necessary to reinforce the bases of the Cloud River and ring seas.

With Jessica's help, these areas were reinforced to three times their previous strength, allowing for a load-bearing capacity nearly ten times greater than before. Then, Jessica used her powers to draw up seawater like a dragon.

After filling Mermaid Paradise and the ring sea with seawater, Jessica only needed to channel the water from the lower ring sea to the higher Mermaid Paradise, which was slightly elevated.

This process didn't require too much energy from Jessica. As long as she didn't cancel her ability, the seawater would naturally flow upward to Mermaid Paradise before returning back to the ring sea.

At the bottom of the ring sea, the Fish-Men worked diligently to construct buildings and commercial streets that reflected the style of Fish-Man Island. 

Bubbles made by bubble corals surrounded the area, creating bubble channels in the water.

Now, this place resembled a new, miniature version of Fish-Man Island. Most of the inhabitants were high-value mermaids and skilled Fish-Men.

An exclusive passage led to Fish-Man Island, accessed through a hole at the bottom of the ring sea. Only merfolk could swim through this passage. Entering from the cave entrance revealed a vast space isolated by corals.

Within this space, numerous small boats using bubble technology floated. The mermaids could use these boats to reach the empty island from the bottom of the ring sea, alongside the floatboat that Arthur had specially prepared for the Neptune family.

Though these changes were substantial, with Jessica's Lion Fruit powers and Arthur's efforts, they were completed in just six days.

Looking at the current Heaven in the Sky, Arthur felt that his vision had truly been validated!

With these matters resolved, Arthur found that he had little left to do in the near future, as the overall plan had been completed or proposed.

Here's a rewritten version of your text in clearer and more understandable English, incorporating the necessary changes related to One Piece:

---

For example, in the case of the WTO, a headquarters will be established on the first layer of island clouds. This will be entirely handed over to the Ministry of Commerce to manage.

As for any possibility of someone pulling strings behind the scenes? That's simply impossible. These officials have almost complete knowledge of Arthur; they know he is aware of everything about them and their actions.

However, they don't understand the immense power of the Thunder Fruit's Observation capabilities. Even though they are aware of the existence of Observation Haki and Devil Fruits, they perceive it as the power of a true god.

The groundwork for the intelligence network has been mostly laid. Minor details are being finalized, and the establishment of the WTO and various commercial collaborations with different countries will quietly unfold. The underground world can now operate independently of Doflamingo.

The two intelligence organizations, one light and one dark, have been assigned to Naz on the surface for his Streamer Army operations. 

The underground intelligence network has been entrusted to Iliad of the Shadow Stream Army, supporting the actions of both Shadow Stream and Void.

Of course, these two intelligence networks have overlapping areas, serving both sides and supporting all three legions.

In this way, Arthur's earlier plans are essentially complete.

The next step is to establish some major companies. However, this will be delayed slightly because Arthur's current objective is to visit Water 7 and secretly acquire the blueprints for Pluto's manufacturing.

When the time comes, the manuscripts will be burned, ensuring no one knows that Arthur possesses these drawings. Moreover, even if Pluto is constructed, it will belong solely to Arthur Ant-Man!

The Sea King and Pluto will be completely under Arthur's control. As for the final king, it is likely that he is just like the speculation and fan theories suggest—potentially a trump card for the Celestial Dragons.

There's no need to rush development! This is Arthur's true strategy for secret growth.

A day later, in the capital of Water 7.

"Hey, young man, try this! It's a specialty of Water 7, water and meat! It's a unique delicacy on the Grand Line!" a bald old man enthusiastically recommended the dish to Arthur.

Arthur nodded, picked up the dish, and took a bite. Although it looked like jelly, it was actually a type of meat with a distinctive flavor. It tasted quite good.

"Boss, I'll have another!" Arthur licked his lips after finishing. He had a hearty appetite and could eat plenty, and this was just the right amount for him.

"Haha, here you go! Isn't it great? First-time customers usually want more than one portion!" the boss laughed, happily bringing Arthur another serving.

Arthur had changed his outfit and disguised himself a bit, making it difficult for anyone to recognize him unless they were very familiar with him.

He planned to secretly copy the drawings from Franky's stomach at night. He also wanted to find out if the Door Fruit had been consumed by CP9's Blueno.

That fruit has impressive powers! It can create doors not only on physical objects but also on living beings, flames, and even in the air.

Additionally, it can create spatial channels. This powerful ability has gone uninvestigated for years, with no news about it.

This time, Arthur wanted to confirm if the Door Fruit had been eaten. If it has, he would need to develop a different plan.

However, one thing is certain: he must master that fruit himself.
