Battle

"Right, there's also a top-tier energy crystal in the Market Ruins vault, condensed within the body of an Overlord-class insectoid. It can also raise the advancement success rate by 10%..."

A flash of inspiration struck him, and Song Chi remembered the top-tier energy crystal he had obtained during the battle when he enslaved Ilis.

That put the success rate above 80%, which was already quite impressive. If something unexpected truly happened, perhaps he could directly attempt the Sky Ruins Firmament's warship advancement.

Of course, that was merely an emergency measure for unforeseen circumstances. Given Song Chi's personality, he naturally preferred to be as cautious as possible. Ideally, he wanted to steadily raise the advancement success rate to the 95% it had been when advancing to a Dreadnought.

Though he knew that would be extremely difficult. After all, this was an advancement to a Star Destroyer. Trying to obtain more than a 30% advancement success rate by bathing in alien blood was practically impossible. He could only prepare as many additional advancement resources as he could, yet what additional advancement resource capable of taking effect during a Dreadnought-to-Star Destroyer advancement was not exceedingly rare and priceless?

Song Chi understood that perfectly well, but he still would not give up so easily.

His thinking was simple: every bit the success rate could be raised counted. Raising it even slightly would likewise reduce the chance of needing to use a Time Realm Fruit.

Each Kindling Warship could only benefit from a Time Realm Fruit once in its lifetime. If he used one during the Star Destroyer advancement, then when the Sky Ruins Firmament later attempted to advance to a Galaxy Warship, it would no longer be able to use a seventh-rank Time Realm Fruit. That was something Song Chi absolutely did not want
