Zheng Yi was advancing to a higher level with the help of the Heaven and Earth Yin Yang Array, while the Ten Thousand Swords Gourd and the Ghost Nurturing Gourd were gradually transforming into the Qiankun Yin Yang Qi Gourd under the tempering of Yin Yang Qi.
Time flowed quietly amidst these silent changes.
...
In the blink of an eye, three years passed.
The entire underground space had only Zheng Yi left. Although it hadn't been exposed to the elements, a thick layer of dust covered the entire area as day after day went by.
Aside from Zheng Yi, no other life forms had set foot here; not a mosquito, fly, or ant.
This was because, at the convergence of yin and yang, the Earth Vein generated Yin Yang Qi that evolved here, and coupled with Zheng Yi's magical power fluctuations, any creature, even the smallest life form, instinctively stayed away.
Moreover, the entire military base was heavily guarded by the Soul Hall, so not even a mosquito could fly in.
