It is a special energy that exists in the cave creatures, and Colin named it the "cave factor."

The burrow factor is basically present in most burrow organisms. The reason why O'Neill mentioned some plants was because he had only eaten those kinds of burrow plants.

But Alec is different. Over the course of hundreds of years, he has eaten almost all the cave creatures that are common in the shallow layers of the cave, and basically all of them have been helpful in practicing the Giant Mountain Breathing Technique.

This is consistent with Colin's research results.

According to tests, the burrow factor is not only extremely difficult to detect, but is also inert and does not react with magic, spirit, or even blood or fighting spirit.

If an ordinary person eats a cave creature, the cave factor will enter the human body, but it will only be temporary and will slowly disappear over time.

But in the knights who practice the Giant Mountain Breathing Method, its performance is not the same - the cave factor will stay in the body for a long time and gather towards the heart!

The specific reason is still unknown, but Colin speculates that this may be related to the fact that the Giant Mountain Breathing Method directly strengthens the body, rather than indirectly strengthening the body through blood.

Generally speaking, for ordinary knights, most of the physical enhancement is indirectly brought about by the continuous nourishment of blood. This situation becomes more obvious in the later stages.

After all, ordinary exercise can easily strengthen the external muscles, but it is difficult to improve internal aspects such as vision, five senses, and even digestion.

The reason why the knight's practice can be regarded as an extraordinary path is because the improvement that blood nourishment can bring about is in all aspects, which cannot be achieved by simple physical exercise.

However, even if blood nourishment is used, the improvement of the physical body is limited, and the upper limit will usually be reached at the stage of the great knight.

At that time, everyone will be competing on the accumulation of blood and combat experience.

However, the Giant Mountain Breathing Technique is not like this. It directly strengthens the body, rather than indirectly strengthening the body through blood, and it can continue to strengthen during the Great Knight stage.

Because he had practiced too many knight breathing techniques and his own body was too strong, Colin had not discovered this before.

And even if I noticed it now, I still couldn't find any difference between the body directly strengthened by the giant mountain breathing method and other bodies indirectly strengthened by the knight's blood.

However, since the burrow factor will show different reactions to the two, this means that the two are indeed different, but further research is needed.

It's a pity that time is never enough, half a month has passed.

When he left, he only allowed Wilbur to cover for half a month - although the latter said that even two or three months would be no problem.

But to be on the safe side, Colin still planned to go back to Jinmaisui first.

Moreover, he had to find a way to solve the duty issue and devote as much energy to knight research as possible.

Although according to the current progress, in more than half a year at most, all the knight's breathing techniques on the gold paper will be integrated to break the limit.

But it will probably take several more years to practice the new fused breathing method to the point where it breaks the limit, and to be able to take a further step on the path of knighthood.
