The first thing Ji Yuan wanted to upgrade was the Formation Room.
On his way back from the Water Dragon Sect, he would have brought back a formation or two if he had enough Spirit Stones.
One would be a Bewildering Formation to conceal Mist Island; the other, a conventional killing formation for fighting enemies.
The Yin Ghost Formation he carried was useful, but once he deployed it, he would have to kill his opponent. He dared not risk being mistaken for a Demonic Cultivator on Water Dragon Sect territory.
As for the Kitchen, he had seen what the building could do back when he was still in Zengtou City.
Its Spirit Effect could not increase his strength, though. It could only satisfy his appetite.
At the time, Ji Yuan had felt he was not yet at the point of spending Spirit Stones and effort on food, so he had put off upgrading the Kitchen.
Now, he thought he could afford to give it a try.
Cultivation was a long, bitter road. He ought to make himself comfortable along the way, or what was the point?
He would have to experiment with the other buildings gradually.
With that in mind, Ji Yuan took out paper and brush, wrote "Kitchen," and stuck the paper inside the little wooden cabin where he lived. He waited a moment, but no Kitchen appeared above his head.
In that case, he would have to build a new room beside it.
Apart from last year's New Year meal, Ji Yuan had rarely cooked. Even when he did, he usually settled for a barbecue.
Naturally, he had no need to build the room himself.
He called Tu Yue back from digging soil in the mountains and told her to build it, then went into the stone cave.
