Wang Ping was taken aback, not quite understanding why Brother Yuan thought Yan Yu Tower was not so simple, but since Brother Yuan said so, there must be his reasons.

He immediately expressed his understanding and advised his father to switch brothels for the next few days after returning home.

Chen Yuan nodded. He had given all the necessary instructions. If Wang Ping didn't listen, there was nothing he could do, and he couldn't help him.

Of course, he knew Wang Ping's character somewhat and knew that he wasn't a mindless guy who didn't listen to advice.

If that were the case, Chen Yuan wouldn't have approached him in the first place.

After instructing Wang Ping, Chen Yuan used his authority as a constable to summon all the yamen runners in the county yamen, telling them that he would be taking seven days of leave.

Everything would remain as usual. If anything unexpected happened, they should report to the county commandant immediately.

After saying that, he ignored everyone's speculation, sat quietly in the constable's office for an hour, and then left the county yamen alone.

In the small courtyard, Chen Yuan cleaned the house and set up some inconspicuous traps at the door, nothing lethal, but capable of leaving traces.

After that, when it got dark, Chen Yuan, dressed in ordinary long robes, quietly left the county town.

......

......

South of Ping An City, about seven or eight miles away.

Chen Yuan chose this place to break through, deep in the mountains and forests, quiet and uninhabited.

He would not choose to break through in Ping An County, especially not at his own home.

It was prone to accidents.

This time, his goal was to enter the Bone Refinement stage. What would happen during the process was still unknown, but choosing a secluded and uninhabited place to break through was certainly the right thing to do.

It was a continuous small mountain, not high, but it was certainly no problem to hide a person.

The moonlight was bright, and Chen Yuan held a torch in his hand, able to clearly see the road ahead. He walked upward, erasing the traces he left behind as much as possible along the way.

Before long, Chen Yuan reached the summit. Looking into the distance, he could vaguely see the outlines of the county town.

Finally, Chen Yuan found a large bluestone, several zhang wide, with a relatively flat surface. After carefully cleaning it, Chen Yuan explored within a hundred meters around it.

After confirming that there were no problems, Chen Yuan took out several pre-made bells from his pocket and placed them in hidden locations.

It's always good to be cautious.

And he, Chen, has always been relatively cautious.

After all, he only had one life, and once it was gone, it was truly gone.

After completing all the preparations, Chen Yuan stuck the torch in a pile of dirt, placed the change of clothes aside, leaped up, sat cross-legged on the blue boulder.

Chen Yuan exhaled a long breath, then slowly closed his eyes.

The night passed without incident. Chen Yuan circulated the blood and Qi within his body. At his chest, wisps of coolness seeped out from the Marrow Cleansing Spiritual Pearl, spreading to his limbs and bones.

Chen Yuan could feel that his body seemed to be lighter.

Of course, he also knew that this was an illusion.

In reality, the Marrow Cleansing Spiritual Pearl was cleansing the accumulated pill toxins in his body.

The next morning.

When the first ray of sunlight appeared on the horizon, Chen Yuan suddenly opened his eyes and braced himself with his arms.

"Tear!"

The clothes on his upper body instantly tore and shattered, revealing Chen Yuan's toned muscles.

The slightly bronze-colored muscle blocks were distinct, streamlined, without any excess fat, showing a healthy beauty.

Chen Yuan stood up and struck a strange pose that ordinary people could not do. Soon, a layer of dark golden light appeared on his body, shining brightly in the refraction of the sunlight.

Nearly three hours later, Chen Yuan shook his arm and flipped over on the bluestone, sitting cross-legged again. Sweat dripped from his body, already soaking most of the blue boulder.

"Crack."

Chen Yuan reached out and opened the red wooden box in front of him, revealing the four porcelain bottles inside.

......

On the first day, Chen Yuan swallowed and refined eighteen Tiger Bone Pills, completing the eighth Blood Refinement. If one could pierce Chen Yuan's skin, they would be able to see that Chen Yuan's blood had already begun to transform in a golden direction.

Ordinary cultivation methods only require three Blood Refinements to begin attempting to break through to the Bone Refinement level, but the potential of one's own physical body has not been stimulated. Although it is fast for a while, it sets an upper limit for oneself.

Of course, this path is suitable for most people.

Nine Blood Refinements require too many resources, which ordinary people simply cannot afford. The imperial court would not waste so much money to cultivate martial artists on a large scale.

Take Chen Yuan as an example. For nine Blood Refinements, he has refined nearly a hundred Tiger Bone Pills, including Blood Nourishing Pills, which translates to thousands of taels of silver.

Not to mention that ordinary people cannot obtain cultivation pills, even if they could, how many ordinary people could afford such expenses?

If it weren't for wanting to solidify his foundation, Chen Yuan would have already stepped into Bone Refinement.

After completing the eighth Blood Refinement, Chen Yuan sat cross-legged on the blue boulder for a night. In addition to eating and drinking, he spent two consecutive days cultivating the Vajra Glazed Body under the scorching sun.

Using the power of the sun to enhance the cultivation method, and the Marrow Cleansing Spiritual Pearl within his body to minimize the discharge of accumulated pill toxins.

On the fourth day, Chen Yuan swallowed and refined all the remaining Tiger Bone Pills, completing the ninth and final Blood Refinement, with Qi and blood surging within his body.

Chen Yuan tested his strength. With a single punch, he could create a sound in the void.

The power contained within it reached an astonishing level.

The golden lacquer on Chen Yuan's body became increasingly dense, and the dark golden light covered his entire body, highlighting the beauty of power.

After that, Chen Yuan continued to cultivate the method, spending another two days expelling pill toxins.

At this moment, some foul-smelling black mud appeared on his skin again.

Chen Yuan wiped it frequently with the scraps of cloth next to him without changing his expression.

In the blink of an eye, six days had passed.

On the seventh day, Chen Yuan adjusted his state to its peak. His pectoral muscles slowly pulsed, demonstrating Chen Yuan's vigorous vitality. His entire body was like a golden man.

Apart from his hair, everything was in a dark golden state.

"Huff..."

Chen Yuan exhaled a long breath, glancing at the scorching sun hanging high in the sky.

Then, he closed his eyes tightly, mobilizing the power of Qi and blood within his body while circulating the Bone Refinement level of the Vajra Glazed Body cultivation method, and began to cultivate!

Through the flesh, that faint golden blood that Chen Yuan had transformed through the cultivation of the Vajra Glazed Body, began to gradually permeate toward the bones of the body with a magical traction force.

It seemed that he wanted to transform the bones of his whole body into a light golden state as well.

After two consecutive hours of continuous cultivation, Chen Yuan opened his eyes very calmly. He looked down at his arms and could clearly feel the powerful power contained within them.

Bone Refinement!

After seven days of cultivation, he finally stepped into the Bone Refinement stage!
