Who made the furnace of the sun god?

The character of this novel is Yu Heng the Great.

Yu Heng the Great is a character in Chen Dong's classic Xianxia novel Covering the Sky. He was the Terran Emperor more than 100,000 years ago and was born in Wei Zixing. He once entered the forbidden area in the early days and used the terrain of Sunset Ridge to refine the Sun God Furnace. After his success, he struggled with this incomparable strong man for many days and finally killed him.

Before Emperor Heng became emperor, he used Vulcan furnace to kill people all over the world. After Taoism was confirmed, he got the magical material equivalent to the sacred bone-Huang Xue Jin Chi. He wanted to be refined into an extreme weapon. In his early days, he went to the Red Moon Cave and the Fallen Ridge in the restricted area to offer sacrifices to the emperor's soldiers. Even because of the lack of yang, it was sucked up. This makes a constant furnace, an extreme weapon hammered by Huang Xue and Jin Chi.
