Sea Train and the Red Line Tunnel!

Sea Train!

Imu was taken aback when he heard those four words, because he had nearly forgotten about this research project.

In his mind, this was something that would take at least ten years.

Yet only barely five years had passed.

He took the report Stussy handed him and read through it carefully.

Only after finishing did he realize he had somewhat underestimated the World Government's pace of progress in technology and materials.

According to the report, the accelerated development of the Sea Train was not only inseparable from Tom's leadership, but also influenced by several other factors.

First, Gairam's arrival had provided considerable help.

He was a former shipwright of the World Pirates and a Paramecia Cube-Cube Fruit user. Due to his exceptional shipbuilding skills, the World Government had assigned him to the Ship Research Institute, where Tom served as dean.

Besides that.

Dr. Stylish, who had only recently joined the Academy of Sciences headquarters, had also provided Tom with advice and assistance in the field of materials some days ago.

The key material was Liquor Iron Ore, produced on Wano Island!

It was a mineral that produced a miraculous effect when mixed into metal, giving it a certain "drunkenness"—in other words, softening it.

The reason Wano Island could process incomparably hard Seastone was, in fact, because they made use of Liquor Iron Ore's properties.

With his super-genius research mind, Dr. Stylish developed a new alloy using Liquor Iron Ore, Seastone, Kabane heart membranes, and the flesh and blood of marine Danger Beasts as core materials.

While maintaining—and even increasing—its strength, this alloy possessed flexibility comparable to the blood vessels inside Sea Kings, and it could also emit the distinctive oceanic aura of Seastone.

What was more, even if this alloy was damaged or outright broken, it could absorb
