Life Force Tree II

The seed absorbed all the Knight-class essence roses and moved to Lord-grade essence roses. 

It had taken seven seconds to absorb the first, six seconds to absorb the second, four seconds to absorb the third, and one second to absorb the fourth. 

By it is the fifth essence rose of Lord class, it had been absorbed in less than a second; after that, Lord class essence roses began to disappear one after another, and before I knew it, all seven hundreds of them had vanished, and it moved toward the Duke class essence roses.

The same thing begins to happen with Duke class essence roses.

While it absorbs essence roses and a huge amount of growth energies, there was no sign of germinating.

This is the seed that is not easy to grow; it takes years for one to know whether germination failed or not, while this process quickened by the thousands of times with the growing energy.
