Life Energy Seed

The Life Energy Seed is the Qi a fighter could develop from inside his body by training himself in the most extreme ways. It somewhat worked like a skill that could help you take hits without getting hurt. The Life Energy Seed was the most important thing for a warrior, and one would not become a true legend without the help of the seed.

Acquisition Method [Extreme Method]
After the stimulation of ones true potential, one would be able to get the Life Energy Seed, and the seed would help one to reach another level. With the help of the seed, one would become a knight after contributing to important tasks.

Not everyone could develop the seed. Only the talented ones could have the potential to do it, but the rate of success was still very low.

Acquisition Method [Implant Method]
Some of the strong warriors with the seed tried to help more people to develop it, and they came up with a specific method, which was by channeling their own Qi into others. People who got the Qi would be able to develop their seed slowly.

Early Implants
It was better for children to get the seeds when they were young. If they obtain the seeds at an early age, the seeds would grow stronger with the children. The stronger their seeds were, the stronger their bodies would be, and when they became adults, they would have well-developed bodies.

Advantages
This method increased the possibilities of the development of the seed, and it also reduced the risks significantly. People could die from trying to do the extreme trainings, and this method helped some people obtain the seed from the beginning.

Limitations
However, this method could not help everyone become great warriors. The rate of success was increased, and two-thirds of them could actually benefit from this method, but the remaining one-third was still not able to take the seed in. If people's bodies could not take in the life energy, the energy would just leak out of them, no matter how much was put into them.

Evidently the original Angele was included in that 1/3 making him give up on training all together

When a knight helped others get Life Energy Seeds, he would lose a small amount of stamina himself.
