Chapter 351: Sun and Moon Nether Emperor, Old Monster

Late Summer.

Human World Peak, Heaven-Defining Peak.

Gu An was rolling up his sleeves writing in the courtyard, while the masked An Xin practiced cultivation beside him, a gentle breeze stirred the scene into something quite picturesque.

An Xin suddenly opened her eyes and asked curiously, "Master, what cultivation level have my senior brother and junior brother reached now?"

Gu An replied casually, "Your senior brother has reached the fifth floor of the Profound Heart Realm, and your junior brother is at the first level of the Integration Realm."

"That high?"

An Xin couldn't help but widen her eyes.

"You take a look at Heaven-Defining Peak; do their cultivation levels seem high here?" Gu An's words rendered An Xin silent.

An Xin carefully asked, "Master, do you really think I can become an immortal?"

Her current actual cultivation level was only at the 8th floor of the Core Formation Realm, and compared to An Hao and Yang Jian, she felt far behind.
