Having transmigrated into a pirate world, Lu En activated a card-collecting system, allowing him to pick up attribute cards dropped by others; the stronger the person, the higher the level of the dropped cards! So, Lu En began to ponder. Infiltrate the Navy? No, too many restrictions! Infiltrate Kaido's crew? Charlotte? Or Whitebeard? The first two are too dangerous, and as for the latter, Lu En had no intention of finding a father figure. Therefore… Lu En decided to infiltrate Shanks' ship as an apprentice! Shanks: "I never dreamed that after all these years, Mihawk couldn't defeat me, Kaido couldn't defeat me, and even Whitebeard could only fight me to a draw, I would be defeated by an apprentice on my ship!" Sengoku: "As everyone knows, the most terrifying person on Shanks' ship is an inconspicuous apprentice!"
