Training Complete · Ghost Mulberry Island

Although he had already reported it to Hina, he did not rush to leave. Instead, he trained for another seven days.

Over those seven days, not only did he completely master portals, able to instantly open any portal he wanted with a single thought, but he also developed the dimensional-space function Bruno had created in the original story.

Because this dimension was covered in green everywhere and had the eerie feel of a ghostly realm, Yang Yunzhi named it the Spirit World.

He did not know how long Bruno had studied the fruit after obtaining it, but Yang Yunzhi felt that what he had achieved in these seven days was already more extensive than what Bruno had developed over several years.

But he soon discovered that something seemed off about this Spirit World.

First: it could indeed be used for storage, but it was not portable.

Simply put, if he opened a dimensional space at Base 36 and stored items inside, then opened a dimensional space somewhere else, he would not be able to find them. He had to return to Base 36 to retrieve them.

Second: this space could not be used as an office either, because there was no air inside. People could not stay there for long!

Still, it was not a major problem. If he did not have a Portable Space, he could develop one himself.

Using his own Portable Space as a reference, he quickly developed a Devil Fruit version of a Portable Space.

This Portable Space was far larger than the one granted by the system. The system space was still only thirty-two cubic meters, but the Portable Space developed through the Door-Door Fruit alone had the area of a football field and was nearly twenty meters tall.

It could easily hold an entire ship!

However, he did not completely abandon the Spirit World. Instead, drawing on the Pathway of Door from Lord of Mysteries, he developed an ability called Dimensional Roaming.

That was because there was nothing in the dimensional space: no air and no gravity. Naturally, there was no wind resistance, much less gravity.

Moving through dimensional space was like moving through outer space. With only a slight increase in speed, one could shoot up to an incredibly high velocity.

He could accelerate in reality before opening a portal and slipping into the dimensional space. In reality, his speed was at most twenty meters per second, but in the dimension, it could exceed three hundred meters per second.

Three hundred meters per second was naturally nothing to admirals or vice admirals, but for a lieutenant, that speed was utterly astonishing!

As for what use this ability had?

Honestly, it was extremely useful.

Yang Yunzhi had no intention of exposing his Spark Portal ability, but the One Piece World was so dangerous that he would inevitably encounter situations of extreme danger where he needed to flee.

If Spark Portals could not be exposed, then wouldn't Dimensional Roaming come in handy?

Besides Dimensional Roaming, Yang Yunzhi also developed Mirror Space.

When he first began developing Mirror Space, Yang Yunzhi had been somewhat apprehensive, afraid that the Door-Door Fruit might be incompatible with Mirror Space.

But he ultimately succeeded in developing it.

If the Spirit World was a world without air or water, unsuitable for human survival, then Mirror Space had people, mountains, and even water!

Unfortunately, all those things were false, mere projections. He could see them, but he could only see them.

He could not smell them, could not sense their presence, and could not hear the sounds they made.

Yang Yunzhi also discovered that he could not manipulate the mirror world as freely as the Ancient One. He could not interfere with it at all, much less control the buildings within it for battle.

That made him realize that the Ancient One's Mirror Space might not be merely spatial in nature. Perhaps it also incorporated dream-related abilities.

But Mirror Space was already difficult enough to develop. As for dreams, Yang Yunzhi did not dare hope for that yet.

Seven days later, on the twenty-third day since Yang Yunzhi had enlisted, he felt that he had developed the Door-Door Fruit's abilities sufficiently. At last, he decided to leave Glass Island and begin forming the Military Intelligence Office.

As the saying went, choose the generals before the soldiers. To establish an Intelligence Office, the first thing he needed to do was choose a capable person to take charge of it.

And for that position, naturally, no one was more suitable than Robin!

It was not because Yang Yunzhi was lustful. Robin genuinely had the ability.

Ten years later, Crocodile formed Baroque Works, but with Crocodile's intelligence, he was clearly only a figurehead. Robin handled the bulk of the work.

Even while shouldering both Baroque Works and Rainbase Casino, Robin had managed to develop both ventures remarkably well.

There was no need to mention Rainbase Casino. It was a money pit.

And Baroque Works?

It had numerous members and a clearly defined hierarchy. Not only was the organization spread across Alabasta and capable of plotting a massive rebellion involving hundreds of thousands of people, its influence stretched across several islands, and it had even occupied an island at the entrance to the Grand Line.

From Zoro's words, they could also see that Baroque Works' reach even extended across the Four Seas. They had gone all the way to East Blue to recruit people!

That was all Robin's achievement!

Letting such talent go unnoticed was more than wasteful. It was simply absurdly wasteful.

It was even more ridiculous than sending Qi Tongwei, with a graduate degree, to serve as a township judicial officer!

If only Aokiji had not been so outrageous and had simply recruited her into the Marines, how could pirates have run rampant for so many years? With Robin's schemes, the Marines might have wiped out the Four Emperors long ago!

Still, it was a good thing he had not recruited her. If he had, what chance would I have had?

Yang Yunzhi first left Glazed Town and took a ship to Gem Country. Then he bought a large amount of food in town and stored it in his Portable Space before finding an inn to stay in.

At the inn, Yang Yunzhi activated the Byakugan and selected a luxurious ship bound for Luminous Island.

After the ship set sail, Yang Yunzhi directly opened a portal and teleported into an empty room aboard it.

Ships like this were exceptionally luxurious, so their passengers were naturally either wealthy or influential. Tickets were generally checked only when boarding and disembarking, and naturally would not be checked during the voyage.

The luxury suite Yang Yunzhi had chosen even came with its own bathroom. Since he also had plenty of food in his space, he could simply remain inside without coming out until the ship reached Luminous Island.

He was not trying to save that little bit of money. He simply did not want anyone to know his route.

Five days later, the ship arrived at Luminous Island.

Yang Yunzhi left using a Spark Portal, then boarded a ship bound for the next island in the same manner.

The Byakugan's observation range was still too short. If he could directly see the next island, why would he need to take a ship? He could simply teleport there.

But while the journey out was long, returning would be easy. He only needed to use a portal to come back.

So although he traveled far, he could actually cross vast stretches of sea and return to Base 36 within seconds, keeping his promise to Hina that he would return at least once every week.

After a long journey of twenty-one days, he finally reached his destination: Ghost Mulberry Island!
