The lights are gathered together, and even the night cannot block it.

Baiyujing is the largest city in the world.

Baiyujing covers an area of ​​about 19,000 square kilometers and has a population of more than 50 million. It consists of eight outer cities, four inner cities, the fourth floor of the Sun, Moon and Stars, and the centerpiece of the Chengtian Tower.

This city alone could support the capital of the Yuntian Emperor's separatist rebellion in the past, which can be said to be unprecedented.

However, time has changed and the scene has changed. A large number of fields between the eight outer cities have been turned into urban buildings. The highly developed transportation is enough to transport the grain produced by the surrounding states and counties to supply Bai Yujing for use.

Nowadays, most of the city walls in the four inner and eight outer cities of Baiyu Jing have been demolished, leaving only a few parts as cultural monuments.

Gao Han lamented the greatness of this city.

Haixing City is a very large city in Gao Han's eyes, but driving from Haixing City from the east to the west will not take more than forty minutes if there is no traffic jam.

In Bai Yujing, the journey from getting off the airship to Fangqing Garden took nearly three hours.

Gao Han sighed for a while, regained his energy, and started today's practice.

Compared to Senior Sister, I am still far behind;

Compared to King Snake Taoist - this is incomparable.

Don't slack off.

Gao Han followed the Heavenly Snake's inheritance, twisting his body and channeling his internal energy into his bone marrow!

This is not difficult for Gao Han. His internal force travels through the spine and internal organs from the beginning, so it is not difficult to pass through the spine.

Now it is necessary for internal force to penetrate deeply into the spinal cord, thereby stimulating the spinal cord to secrete new blood, thereby guiding the internal organs to develop in a direction that is more adaptable to internal force.

This is - the Heavenly Snake Bone Tempering Method!

Gao Han contorts his body like an earthworm stretching and crawling. It's a bit ugly, but as a cultivator, he doesn't care about face when no one sees him, so it just works.

One quarter, two quarters, three quarters, four quarters - until the eighth quarter.

Starting from the tail vertebrae of the spine, each segment of the spine has a special guiding posture in the Tian Serpent inheritance, which can help Gao Han control the internal force, penetrate into the bone marrow little by little, and subtly affect the bone marrow.

At the same time, some impurities in the bone marrow are brought out from the tiny holes on the bone surface.

When there are too many impurities in the internal energy and it is no longer pure, Gao Han will spit out the impurities, and the Qi and Blood Danzhu will jump out and absorb the power of Qi and blood to strengthen itself.

This cycle continued until the life energy overflowing from the body in one day was no longer enough to support the internal strength to continue refining the bone marrow, and Gao Han had to end today's practice.

At present, Gao Han has completed the initial refining of the three sections of the coccyx and the five sacral vertebrae, but it is not yet pure enough and the fire is not enough to progress to the refining of the five lumbar vertebrae.

If the lumbar spine refining is completed, Gao Han's body flexibility will reach a new level.

If he completes the refining of the entire spine, Gao Han will face the challenge of refining the brain. If he successfully refines the brain, the internal force can gradually turn into true energy under the control of the brain that has undergone qualitative changes.

If it fails, at least the brain will be injured and there is a risk of becoming an idiot; at worst, the brain will turn into a ball of mush and you will directly become a vegetative state.

Gao Han's small goal is to refine his spine and brain and cultivate his true energy.
Chapter completed!
