Douluo Continent: What should I do if I don't have a cheat system?

The protagonist, Jerry, is a recent graduate who can't sleep at night. He lies in bed reading a book and wakes up to find himself transmigrated into the world of Douluo Continent.
I originally thought that as a transmigrator with a cheat code, I would understand the plot and then overthrow the two great empires, defeat the Spirit Hall, the Clear Sky Sect, the Seven Treasure Glazed Tile School, and the Blue Lightning Tyrant Dragon Clan...
Stealing the immortal herb, treacherous to Tang San...
Carefree and at ease!
The idea turned out to be naive, but reality proved harsh.
Martial Soul Awakening: Ancestral carrot martial soul, half-level innate soul power, and no cheat codes yet.
If not, then so be it! I'm a modern person, how could I be stumped?
Modern knowledge and perspective are the key to success!
Since we can't make a big splash, we should develop our strength stealthily and eventually stand at the top of the world.
Hehehehehehe...
