Upon hearing this, Jellyfish Yin Ji suddenly recalled the color changes of the sword energy in the courtyard earlier, and immediately gasped.

"In other words, after entering the Dao Sword Realm, one is already able to completely master the power of heaven and earth and control the changes in this power?"

Chu Qinghe nodded and said, "More or less!"

The power of heaven and earth is mysterious and profound, and it is also the foundation of heaven and earth.

Being able to control the changes in the power of heaven and earth can already be described as "transcending the mortal realm and entering sainthood".

Normally, only when a martial artist enters the Yangshen realm can they condense the Daoist essence and completely master the power of heaven and earth.

Unexpectedly, when swordsmanship reaches its peak, it can also condense the essence of Tao.

Then, Chu Qinghe waved his hand and said, "Alright, you're only at the third level of swordsmanship right now. Knowing too much about this stuff will only do you harm."

Hearing Chu Qinghe's words, the group could only suppress their curiosity and head towards the inner courtyard.

After the group returned to the inner courtyard, Chu Qinghe once again focused his attention on the system inventory.

After pondering for a moment, Chu Qinghe had an idea.

"System, use Immortal-grade Martial Arts Upgrade Card."

The thought had barely formed when a system notification popped up.

Please select the recipient of the "Immortal Martial Arts Upgrade Card".

Subsequently, the martial arts and even techniques that Chu Qinghe possessed were listed one by one by the system.

Since martial arts techniques are the foundation of a martial artist, Chu Qinghe's first choice was naturally his own "Innate Body-Breaking Formless Sword Qi".

After the user of the "Immortal Martial Arts Upgrade Card" was selected, the system returned to calm.

In the past, when using upgrade cards, Chu Qinghe's chosen martial art could be upgraded in the shortest amount of time.

However, this time Chu Qinghe waited for nearly a hundred breaths before the system notification popped up.

[Ding! Congratulations, host, your "Innate Body-Breaking Formless Sword Qi" has been upgraded to Immortal Rank.]

The moment the notification appeared, a flood of information rushed into Chu Qinghe's mind.
