Yan Kunlun's Heart!

Hearing Xue Zengwu say this, Chu Yun had already gained a detailed understanding of the heart's purpose.

Indeed, if it were fused, the most likely outcome would instead be exploding to death.

After all, what it contained was a Heaven Ascender's divine power.

Even one at the absolute peak of Half-step Ascending Heaven, having crossed the eighth Heavenly Bridge, was still as different from a Heaven Ascender as clouds were from mud. There was simply no comparison.

"With this Heaven Ascender Divine Source, a Half-step Ascending Heaven cultivator would have an immense chance of advancing further."

"No wonder those outside are so covetous. This truly is a rare, supreme treasure."

Chu Yun deeply agreed. Immediately afterward, he attached a strand of soul perception to the surface of that divine source heart and carefully sensed the origin aura of the Heart Divine Source.

Less than a few seconds later, his expression suddenly shook.

He decisively withdrew his soul power, his heart filled with shock.

This was exactly the same as his previous guess.

The source of this Heaven Ascender heart was actually him!!

The previous Grand Sect Master of the Four Mad Demon Sects, Yan Kunlun!!

But what Chu Yun could not understand was how part of Yan Kunlun's remains had ended up within an ancient ruin.

Yan Kunlun had fallen after sealing away the remnants of the Four Mad Demon Sects. Could something else have happened during that time?

Chu Yun kept this question in his heart, planning to ask Du Qian Yue about it after they left and see whether he knew what had happened.

"Senior, the first supreme treasure is the Heart of Heaven Ascender. Then what is the second?" Chu Yun asked.

"The second is this old man," Xue Zengwu said with a smile.

"Ah?" Chu Yun
