Thunder Void, Tenth Heaven.

After leaving the Emperor Road, Xiao Yun came here to temper his physical body.

With his current physical body and cultivation, he could withstand even entering the Tenth Heaven of Thunder Void.

The power of lightning here could destroy Quasi-Emperors, yet it was difficult for it to destroy Xiao Yun's body.

A physical body at Xiao Yun's level had already surpassed that of many Great Emperors.

Even Great Emperors who had attained the Dao found it difficult to possess such a formidable physical body.

What made Great Emperors powerful was their 'Dao,' not their physical bodies.

After all, very few cultivators could train their physical bodies to Xiao Yun's level.

What was more, those Great Emperors did not possess a supreme body-tempering technique like the Eight-Nine Arcane Art.

Even in the Primordial World, the Eight-Nine Arcane Art was among the most pinnacle body-tempering techniques.

The only one perhaps slightly stronger was the Nine-Nine Arcane Art cultivated by Pangu. It was a terrifying technique for cultivating the true body of Pangu and proving the Dao through force.

Xiao Yun very much wanted to obtain this technique, but even in the Primordial World, it was difficult to acquire. Probably only the Three Pure Ones Saints possessed such a technique.

Boom! Boom! Boom!

Within the boundless sea of purple lightning, Xiao Yun bathed in bolts as dense as rain, drawing out the potential of his physical body as he charged toward the Ninth Heaven of the Quasi-Emperor Realm.

Unfortunately, his body remained trapped at the peak of the Eighth Heaven of the Quasi-Emperor Realm, unable to advance into the Ninth Heaven for a long while.

Tempering the body was even harder than raising one's cultivation. The further one went, the harder it became. Unless he encountered another fortuitous opportunity,
