The Motor Sound Summoning Tower was incredibly useful to Liu Zhi. In the future, whenever he wanted to build a Summoning Tower, he would no longer need to use his own equipment or Soul Gems as he had before. He only needed to use this blueprint to build at least seven Summoning Towers repeatedly.
Most importantly, these Summoning Towers could connect with one another.
There was a connection between these Summoning Towers.
This connection was extremely important. Once the Summoning Towers were built, all souls could move freely between them.
It could be said that the Motor Sound Summoning Tower was enough to let Liu Zhi support at least seven ghost domains.
That was enough for Liu Zhi to build his own ghost domains up to ten in number and support all the requirements of his level-eight Ghost Domain Lord.
"It's really great."
Liu Zhi let out a long sigh and reached out to pick up the Motor Sound Summoning Tower.
Afterward, his eyes involuntarily turned toward another architectural blueprint.
Liu Zhi had been a player for many years and could be said to have seen countless kinds of architectural blueprints. There were all sorts of concepts among them, but he had truly never seen anything like the one before him.
At the very least, Liu Zhi had never seen anything based on this kind of concept.
The thing before him looked like a huge lump of sticky material. When Liu Zhi held it in his hand, this black object, which should originally have been shaped like a statue, melted and flowed out through his hand.
This was a situation Liu Zhi had never encountered before.
After looking at the items' attributes, Liu Zhi came to a conclusion.
