A billion years of lifespan?
What a huge scam!
Han Jue subconsciously wanted to choose "No", but he still hesitated.
Although he had a lifespan of ten trillion years and it was not a big deal to use a billion, he couldn't bear to do it.
He was afraid that he would become addicted.
The constant cursing was already consuming his lifespan. If he added another derivation function, would he expend himself to death in the future?
However, spending 0.001% of his lifespan to understand the future development of the Heavenly Dao was a great deal!
If it was the Heavenly Emperor, he would be at ease.
If it was an enemy, he could still prepare in advance.
"Just this once. Next time, I won't use the option if I need to spend another billion years of lifespan!"
Han Jue thought silently and made the painful choice.
In an instant, his consciousness began to spin. It was extremely uncomfortable.
