Start with the Mangekyō and leave Konoha with Madara.

Konoha 37, April 9th.

In the northern part of the Rain Country, Stone Ridge Mountain.

The earth was in darkness. From a certain moment on, the sunlight gradually became weaker to a degree visible to the naked eye, and the sky became soft and slightly dim.

Looking up, my eyes penetrated through the layers of dull dark clouds. The outline of the sun was blurry and illusory. The shadow of the moon gradually shifted horizontally, turning into a dark shadow that swallowed up the light and blocked the sun. The entire sky began to undergo subtle changes.

Today is an annular solar eclipse, a special day.

But for someone, this is not just a special celestial phenomenon, but also a turning point in his life and the first step towards immortality.

At the highest point of the entire mountain range, there is a flat stone platform, which provides the best viewing point.

But if you zoom out and look at the entire mountain, the stone platform on the top appears very abrupt, as if it was artificially built by some incredible force that flattened the top of the mountain.

The cold wind howled, and the damp and cold air blew past. It was extremely cold up there.

"Is everything ready?"

"Just wait and see, Master."

Beiliuhu rubbed his hands and looked at the magic circle in the center of the stone platform, his expression unable to hide his excitement.

Shen Yu stood at the bottom of the stairs, looking calmly at the highest platform with an interested look on his face. Uchiha Nen and Orochimaru stood on his left and right respectively.

Today is an important day for him, his cheap apprentice. As his teacher, he certainly cannot be absent.

Furthermore, the "Ghost Geranium Technique", a combined ninjutsu of stealing human genes and blood limits, is an unprecedented and unparalleled ninjutsu no matter where it is placed. Even Kamiya finds it extremely novel.

If Beiliuhu can really achieve the same results as in the original time and space, then his guidance and cultivation back then would not be in vain.

Shen Yu smiled lightly and sat back.

Upon seeing this, Nian beside him immediately clasped his hands, and several wooden vines emerged from the stone platform one after another, interweaving and weaving in mid-air, quickly forming an antique rattan chair for Shen Yu to sit on.

As time goes by, the annular solar eclipse quietly unfolds.

The sky was changing with the wind and clouds, as if it was repainted by an invisible giant hand. The sun's light was no longer as dazzling as usual, but was covered with a thin golden veil.

Through the increasingly tiny gaps, a soft and sacred light emanates.

"Soon... soon..."

Beiliuhu's hands trembled slightly. Even though he had rehearsed it thousands of times in his mind, he still couldn't help but feel nervous when the moment really came.

On top of the stone platform, dense ink-colored spells formed a spider-web-like magic circle, and on the wooden pillar in the center of the magic circle, a dying ninja was hanging. It was the Explosive Style Bloodstain, Hunter, from the Hidden Stone Village.

Beiluo took a deep breath of the cold air on the top of the mountain, letting his excited nerves cool down a little, and began to concentrate.

When the shadow of the moon almost completely covers the sun, only a thin circle of golden edge remains, like a golden ring hanging in the sky, and the whole sky seems to be stained with a mysterious color.

Beiliuhu silently calculated the time in his heart, while climbing up the stairs step by step and standing in the center of the magic circle.

The golden halo brushed across the faces of Shen Yu and others, pouring towards the earth. The mountains in the distance were dyed with a faint golden glow, and the outlines of the trees were clearly layered against the golden light, as if they were in a dream.

This golden ring between illusion and reality hung in the air and reflected in Beiluhu's eyes.

"It's now!"

Beiliuhu crossed his hands and completed the complicated seals methodically, then looked up at the golden ring of the sun, allowing himself to fully bathe in the golden halo.

"Let's fuse! The Devil's Sprout Technique!"

The air seemed to be silent for a moment, and then a shadow spread out from Beiluhu's body and slowly swallowed the hunter on the wooden pillar.

Under the rendering of sunlight, this pool of ink-like substance now glowed with colorful brilliance, wrapping the bodies of Beiluhu and Shou at the same time, forming a colorful giant egg.

This process may seem slow, but it actually only takes a few seconds.

In the stands, Orochimaru, who had been watching quietly, suddenly frowned slightly.

"Nian, do you feel that Beiliuhu's Ghost Bud Luo technique this time is a little different from the previous ones?"

"Is there?" Nian looked carefully and shook his head after a moment. "I don't see any difference. If I have to say, it should be the influence of the celestial phenomenon."

Orochimaru remained silent and silently took note of this phenomenon.

Soon, the giant egg shrank inch by inch, and finally froze into a clear human shape. During the process, the golden ring in the sky gradually closed. Each change was accompanied by a subtle shift in the world's colors, from bright daylight to deep twilight, and then to the gradual return to daily life.

When the shadow of the moon completely shifted away from the sun, the fusion ceremony was completed, and a brand new Beiluhu appeared before everyone.

He has a delicate face and flowing white hair. His appearance is not much different from before, but his body has shrunk a little, as if he is a few years younger.

He touched his forehead and found the bright red mole still there. This was the mark he had deliberately made in order to imitate the Wuji mark on Shen Yu's forehead.

At the same time, this is also the standard he uses to judge himself. After all, the "Ghost Bud Ra Technique" is a combined ninjutsu that first merges and then devours. If the red mole that he cares about most disappears, it means that the devouring has failed... and he will no longer be himself.

Fortunately, he succeeded in swallowing it for the first time!

"Master!"

Beiliuhu looked at Shenyu the first time, his eyes full of joy.

Shen Yu smiled slightly, stood up from the rattan chair, and clapped his hands slowly and firmly.

Under his lead, Nen was the first to start applauding. Orochimaru was disgusted at first, but when he saw Hiruzen's earnest eyes, he couldn't help but be slightly stunned.

He recalled the busy figure of his colleague and brother who devoted himself to scientific research day and night, and finally smiled and applauded vigorously.

Beiliuhu was deeply moved. His eyes suddenly turned red and his pupils became moist. He was about to cry.

"I finally... took this step!"

……

After a while, Beiluhu finally calmed down from his excitement and began to experiment with his own power.

As Shen Yu and others watched, he closed his eyes slightly, feeling the power contained in the chakra in his body, and suddenly froze.

"How about it, do you already have the explosive chakra?" Orochimaru asked first.

"No...it's not explosive release..." Beiluo murmured.

"Let me make it clear first, I didn't arrest the wrong person." Orochimaru spoke decisively, trying to distance himself from the matter.

"It's not your problem. It should be what I mentioned before. During the fusion process, the Yang Release Chakra in the body caused interference, causing some changes in the Baku Release Bloodline Limit."

Beiluhu gave a bitter smile, raised his hand and formed a seal, attracting the unfamiliar chakra in his body and slowly gathering it in his palm.

Suddenly, his entire palm turned black, with a smooth texture and a distinct metallic luster under the sunlight.

"Steel Escape?" Shen Yu blurted out, with a hint of understanding in his eyes.

"Steel Release?" Hearing this name, Beiluo murmured to himself:

"This is good, this is good. Since it is the name given by Master, I will call it this from now on."
