To be honest, they had never seen such vast lifespan energy.
With their current divinity limits of around a billion or so, the few billion years of lifespan they usually carried were basically enough to replenish one full bar of divinity. That was generally sufficient. At worst, they could find somewhere to hide and wait for their divinity to recover naturally.
After all, in the battles these players faced most of the time, they did not spend all their divinity in one place. Instead, they budgeted it carefully.
The divinity influence of their various methods was not calculated directly from their divinity limits as Qin Feng's was, but from the amount of divinity spent. In essence, it was a contest of divinity expenditure against their opponents.
If they had enough lifespan, their combat strength would be several times greater than what they could normally display.
But the problem was that lifespan was actually harder to obtain in Highest Heaven!
The main issue was that the demons in Highest Heaven were too strong on average and too few in number. Their respawn rate was nothing like that in the demon worlds of the Blueprint Worlds.
Even with sufficient combat strength, they still needed to spend a great deal of time traveling and searching for monsters, which naturally reduced the efficiency of acquiring lifespan.
So...
When Qin Feng displayed this ocean of lifespan energy, everyone present fell into indescribable shock. He was giving them lifespan on the scale of hundreds of quadrillions, just like that?

To everyone now, Qin Feng's words were practically an imperial decree.
Since all this lifespan had been given to them by "Salotuen" anyway, they naturally had no need to conserve it. More importantly, they could not
