After seeing off Huo Ling'er and Bai Ling, Yu Yuan released the little broken bell, allowing it to absorb Spiritual Energy and restore its own essence.
After briefly checking it, he found that the essence lost by the little broken bell wasn't too much; it would probably be able to travel through time and space again within a year.
It seems that the biggest consumption in time and space travel isn't the travel itself but the maintenance.
This time he actively chose to bounce back to the present, so the Chaos Bell consumed much less essence.
If that's the case, when traveling through time and space in the future, he could immediately bounce back if it's not the era he wishes to go to, which should save a lot of essence and allow for more frequent travels.
Undoubtedly, this was good news for Yu Yuan.
Now, the time left for him wasn't much!
Especially after witnessing such a future, he deeply recognized this.
