Pneumatic Realm, Gale Knife Technique

Xu Ning quickly walked back to his study.

After closing the door, Xu Ning took out the spirit medicine he had obtained in his trip to Yunze Mountains.

In addition to the two spirit medicines he picked up when he entered the mountains, he also encountered two more spirit medicines when he left the mountains.

Xu Ning absorbed the four spirit medicines, obtaining 22 units of energy in total.

Combined with the remaining 4 units from before, Xu Ning now had 26 units of energy.

'It takes 45 units of energy to reach the pneumatic realm…'

Xu Ning thought in his heart, 'In a few days, I will get three Qi Dans and one Qinglu Dan. They are enough to raise my strength to the mortal realm fifth stage pneumatic realm.'

'Also, it seems like I should buy more spirit medicine with the silver taels I've saved up…'
