The sky has been cleared, the sun has not yet risen, and there is silence and tranquility between heaven and earth.

This is the morning when Li Feng and Jiang Jiutian made an appointment to try to induce qi together. On the straw mat in the courtyard, Li Feng sat cross-legged facing east, his eyes closed, his face was neither sad nor joyful, his body was motionless, but the clothes on his body seemed to fluctuate slightly under the wind. The straw mat was very large, but Jiang Jiutian did not sit on the mat like Li Feng, but stood aside in a very relaxed attitude, also facing the east, his eyes slightly closed. There was another straw mat not far away, on which sat Wang Fuzi and Zhu Zi, but they both had their eyes open, quietly staring at Li Feng and Jiang Jiutian.

According to Li Feng, in order to feel the qi, it seems that there is no need to adopt any fixed posture, just to make yourself the most comfortable, the most relaxed, the most able to concentrate on the qi, and the best to feel the external objects without being disturbed by them. For Jiang Jiutian, he often practices the art of bird play, similar to the posture of birds holding their wings and standing still, which makes him relax his whole body the most, without any tension, not tight, and calm.

The light between heaven and earth continued to increase, and although Jiang Jiutian couldn't really see things when he closed his eyes, he could feel the enhancement of light more and more obviously. Although when people close their eyes, they feel that there seems to be nothing in their vision, not even light, and it seems that it should be said that it is dark in front of them, but if they cover it with their hands, it seems to be much darker than just now. How much more is more, and one cannot say exactly, but the obvious difference does exist, and it is definitely recognized. If it is not a big difference like the one with and without the hand, but a relatively small difference, although it does exist, it cannot be clearly recognized.

For Jiang Jiutian, at the beginning, his consciousness seemed to be wandering and uncontrollable, although he tried to concentrate, he always seemed to realize that the light was brighter, only to find that he seemed to be unconscious just now, and an unknown number of moments had passed. But gradually, as his mind became quieter and quieter, distracting thoughts precipitated, everything around him seemed to be slowly slowing down, and the changes in the morning light seemed to be clearer and more detailed, and the slight changes were perceived by him in an instant.

Light does not seem to be a qualitative property of things, but a thing in itself, just as a stone is a thing, and wood is a thing. It's just that this kind of thing seems to have a more special quality than stone and wood—it can penetrate all crevices.

A crevice does not seem to be a qualitative property of a thing, but a thing in itself, just as stone and wood are both a thing. Compared with stones, wood, etc., the crevice also seems to have a special quality—it contains everything and reveals everything.

In the world, everything that seems to be empty is actually filled with cracks.

The gaps, it seems, are gas.

A pair of human eyes can dye light, making it easier for people to distinguish between different types of light. Except for the eyes, it is not possible to distinguish the differences between the lights by dyeing them, but they are closer to the true nature of the light. Different qi has different tolerances for different light, and through the penetration of light and qi, it is possible for people to distinguish between qi.

Jiang Jiutian savored the slightest change in the morning light, and slowly seemed to be able to feel the surge of qi from it. The surge seemed chaotic, but when you felt it more closely, there seemed to be some kind of indescribable pattern.
