System's Grain Reserve

"System can you let his demonic Qi out now?" Lonemoon pointed to Two Bucks Zuo on the bed and turned towards the cube.

[Of course!]

An 'okay' emoticon immediately flashed on the translucent system cube. Since it gained a body, even its manner speaking became much more humane and it even came with emoticons.

[The seal on him is a very low-level space technique, there are many loopholes, it can simply be released through the back door.]

As it spoke, it flew directly above Two Bucks Zuo, a moment later, the entire cube radiated a white light that swept towards the back of his waist, where the demonic Qi was locked in. A while later, a string of characters that resembled a code flashed across Two Bucks Zuo's body, shreds of black wobbly gases floated out of his body.

Yi Qing promptly conjured a spell, those demonic Qi streamed out like they were being pulled and flowed steadily into his palm. In a short while, a ball the size of a basin was gathered.
