My Dantian is a world

Ah Xu's cultivation talent was not ideal, but he also opened up his Dantian and was admitted to the martial arts class of the Municipal Second Middle School.
However, the Dantian he opened up seemed to be a little different from others.
There was actually a world in his Dantian!
[You ate the meat of the first-level monster Feilingyu, and your world species +1]
[You bathed in the spiritual medicine spring, and your world had an extra hot spring. ]
[You took the spiritual object Zhuguo, and your world had an extra Zhuguo. ]
So, other people's Dantians were places to store true energy, but Qi Xu's Dantian had a different scene.
In the deep sea, scales shone, thousands of fish competed to swim, and thousands of species competed for freedom in the frosty sky;
In the mountain stream, the water gurgled, the spiritual spring Zhuguo bloomed, and the mountains were red and the forests were dyed;
In the rivers and mountains, birds and beasts flew, dragons soared into the clouds, and the vast river and sky were covered with frost.
From then on, Qi Xu's cultivation was like a fish entering the sea and a bird flying into the sky, unfettered by the cage!
"You want to compete with me in true qi? My Dantian is a whole world!"
