The Ancient Scroll's attributes were extremely powerful, but compared to the first Void existence, this one was clearly much more 'stingy.' This made Su Xiao realize that good things like what happened before might never happen again.
After all, the Book of Doors was only the first-place reward in the Battle of the Strong. If it could be exchanged for nine more items on the same level as the Alchemical Codex, then the Book of Doors would not have been used as the first-place reward of the Battle of the Strong.
Su Xiao directly used the Ancient Scroll. A strange energy appeared throughout his body, accompanied by a massive amount of technique-related knowledge emerging in his mind.
This strange energy and technique knowledge needed to be gradually 'digested' by Su Xiao himself. How far he could ultimately reach would depend on him.
Su Xiao felt tempted to use another 'Tree-Born Page' to see whether he could raise his firearm mastery as well, preferably to the Master level.
He quickly dispelled the thought. Trading with Void existences too frequently would severely devalue the 'Tree-Born Page.' The first time he used this item, multiple existences had tried to reach a deal with him. This time, however, only one existence had come.
The existences were too ancient. To them, the 'Tree-Born Page' might be a rare delicacy or supplement. After not seeing one for a long time, they would bid somewhat higher when one suddenly appeared. But when another page appeared again after a relatively short period, the existences had already realized that more 'Tree-Born Pages' would appear later.
Three world progressions was not a short time for Su Xiao, but to existences whose lives were measured in tens of thousands of years, it might only be the time needed for a nap.
