He is ready to start to improve his realm again.
Before the third level of the Heavenly Martial Arts Treasury, Su Fan had looted a large amount of spirit energy from other intruders, and he was sealed in a certain corner of the system space.
With so much spirit energy, he can definitely support him to raise a few more realms!
Pushing open the space-time room on the second floor of the Sky Demon Tower, Su Fan walked in quickly.
He still has things to do tomorrow, so using the space-time room to improve his cultivation is obviously the best choice.
Su Fan sat on the small martial arts training ground in the space-time room, calmly, and in his mind, gave the upgrade order to the system!
Huh!
In the experience reserve, 700 million experience points were immediately lost.
Rumble!
There were waves of tsunamis in Su Fan's Dantian world, and the soul sea expanded in all directions.
At the same time, Su Fan unblocked all soul energy from the system space, and used his mind to channel the soul energy into his own soul vein.
The soul vein is connected to the dantian, and with the injection of a large amount of soul qi, the speed of the soul sea's expansion becomes more and more blocky, and it will soon reach the critical point of seven million nautical miles!
At this moment, Su Fan suddenly made a very crazy decision!
"System, I want to upgrade to a third level!"
Huh!
Another 2.7 billion experience points were lost in the experience slot instantly!
Rumble!
The soul sea, which was about to reach the critical point and slowed down its expansion, once again made a fierce roar!
A whirlpool suddenly appeared in the center of the soul sea, which sucked in a large amount of soul energy, and the barrier of the Dantian world suddenly expanded!
7.3 million nautical miles...
7.5 million nautical miles...
Eight hundred and one hundred thousand nautical miles...
9.7 million nautical miles...
After a short while, the soul sea in Su Fan's body reached 9.99 million nautical miles.
In the last nautical mile, he can completely stabilize his cultivation.
However, the expansion in this last nautical mile was actually very slow, consuming the soul energy that had expanded by a million nautical miles before, and it only increased by half a nautical mile.
Moreover, what made Su Fan feel the most anxious was that there was not much spirit energy left.
