Immortal platform

The Foundation Forging realm referred to condensing the immortal platform above the qi sea. Using one's essence, qi, and spirit, the goal was to condense your own original rune. That rune was the foundation of the immortal platform.
Then you would continue condensing runes on top of it, and once you condensed the ninth one, they would transform into one again. That would bring you to the first Heavenstage of Foundation Forging.
The second Heavenstage involved condensing eight such runes, the third Heavenstage required condensing seven, etc. They condensed higher and higher, creating your immortal platform. In the immortal era, that platform would be your foundation for becoming a god or immortal.
But the Xuan Master was unable to sense the existence of Long Chen's immortal platform. Nor did he see his original rune appear on his forehead.
However, his combat power was dozens of times greater than before. That was a clear sign that he had advanced to the Foundation Forging realm. Even the Xuan Master was unable to tell what was happening.
== Long Chen ==
His immortal platforms were different from other people's. The runes in his body contained two kinds of energy. One energy supported his physical body, while the other was similar to the energy of his qi seas. These two energies supported each other and could unleash immense energy combined.
At 12th heavenstage of Foundation Forging his originally cylindrical immortal platforms suddenly compressed, shrinking one whole level.
When his pillar-like immortal platforms were compressed, they suddenly unleashed a terrifying wave of energy.
== Runes ==
At this time, his 108,000 immortal platforms were once more compressed by some energy, turning into spheres. These spheres were covered in his original runes.
This was something that occurred when normal cultivators attacked the Jade Core realm. Their immortal platforms would turn spherical as they prepared to condense the divine core.
Right now, the only thing remaining for him to do was to strip off his original runes. Then he could step into the Jade Core realm.
These runes were like a layer of protection for the energy inside. Once they were stripped off, through the baptism of lightning, his divine core would truly form.
