One week later, he consumed another 28 trillion cultivation points and 34 million Dao points to advance to a Second-grade Golden Core, again gaining 30 Golden Core Essences.
Two weeks later, he consumed 42 trillion cultivation points and 51 million Dao points to advance to a Third-grade Golden Core, along with 30 Golden Core Essences.
