The news of the wealth-guarding ghost's promotion to T1 had taken Yu Liang by surprise. He clearly remembered when he left Cyber City, the wealth-guarding ghost had not yet been promoted, so had it achieved T1 after returning to reality?
Although the wealth-guarding ghost had its own schemes, whether it was out of friendship or its profit-seeking nature, it would not hesitate to stand by Yu Liang's side. Thus, he was quite looking forward to its upgrade.
After acquiring the universe and a plethora of Paranormal Creatures, Yu Liang became curious about their "Strength Enhancement method."
The only methods he knew of involved either using Strengthening Coupons for direct tier upgrades or grass babies utilized Devil Blood to gain new abilities.
Players improved their tiers by reconnecting with their origin, first accumulating sufficient time in Strange Talk World, and then undertaking profession-specific tasks for promotion.
