Simultaneous Transmigration: We Level Up Alone Across Multiple Worlds

On the edge of the northern mining region of the Land of Iron, there is a semi-desolate town.

The town stretches out along both sides of a dry stream, with a few dozen households, a general store, and a blacksmith shop.

The previous owner of the blacksmith shop was an old blacksmith who died a few years ago, and the shop has been empty ever since.

The anvil is still there, but the bellows's leather bag has been gnawed by rats in several places, and the pliers and hammer hanging on the wall are rusty.

Hinata Chen used the last of his money to rent the shop from the shopkeeper.

The proprietress was a widow in her early fifties. When she looked at Hinata Chen, her gaze lingered on his brown-tinted goggles for a moment.

"Is there something wrong with your eyes?"

"Snow blindness. Afraid of light."

"Dried at the mine?"

"Um."

This identity doesn't require too many details.

Every year, people in the northern mining area of ​​the Iron Country go down the mountain to change professions due to snow blindness, so having an extra blacksmith wearing goggles wouldn't arouse anyone's curiosity.

The first few days were used to tidy up the shop.

Clean the rust off the anvil, replace the bellows bladder, and pick out any usable tools from the wall and re-polish them.

The shop survived.

He's a blacksmith by day.

At night it's a different story.

Beneath the muddy floor of the cubicle lies the entrance to a branch tunnel of the excavated mine shaft.

The original mine shafts ran through the town, with numerous side tunnels, most of which are now abandoned.

Hinata Dust walked along the side alley for about fifteen minutes and found a naturally formed cavity with a ceiling about two zhang high and dry rock walls.

He turned this place into a real stronghold.

The Book of Seals is fully unfolded here.

Two shadow clones were created; one used the Byakugan to scan the jutsu diagram line by line, while the other used the Byakugan to monitor the main body's chakra consumption. The main body sat cross-legged in the center, reading through the diagram line by line.

Tobirama Senju's handwriting was thin and strong, and the explanation of each technique was written down to the key points of operation, without a single superfluous word.

The hand seal sequence, chakra allocation ratio, and maximum duration of the Shadow Clone Technique.

The spatial coordinate marking method of the Flying Thunder God Technique, the stability of the marking, and the correspondence between the instantaneous teleportation distance and chakra consumption.

The principles of soul recall in Impure World Reincarnation, the conditions for human sacrifice, and the methods for terminating the contract.

The core of the Flying Thunder God Technique is to inscribe spatial coordinates on the target; kunai, walls, the ground, and even the human body can all serve as coordinate carriers.

Once the coordinates are inscribed, they will not disappear unless actively erased or covered with a special seal.

The ability to instantly teleport is triggered by chakra activating the spatial fold between the coordinates and the physical body.

Hinata Chen first carved a coordinate on the cave wall, then retreated ten steps away and formed a hand seal.

It can make continuous spatial jumps between two coordinates, with an interval of less than a breath.

"Having enough chakra to jump several times in a row won't affect the battle. The core of the Flying Thunder God Technique's consumption isn't the teleportation itself, but maintaining the coordinates. The more coordinates you mark, the greater the consumption."

He only studied the principles of the Impure World Reincarnation technique, but didn't practice it.

It's not that I can't practice, it's that I don't need to at the moment.

Temporarily put on hold; the priority at present is intercolumnar cells.

The preparation for intercolumnar cell fusion lasted for nearly half a month.

The "Rejuvenation" technique that Tianze Chen synchronized with through the Origin Space appears as a gentler technique in Hyuga Chen's chakra system.

This underlying color will automatically repel Yin-attribute chakra, but will naturally approach Life-attribute chakra.

The woody, bluish-green chakra in Hashirama's cells belongs to an extreme life attribute and, theoretically, has an affinity with positive energy.

Hyuga Chen sketched out a stable sealing technique and made a thin sheet using chakra-conducting metal. This sheet could be attached to the chest to prevent the wood-style chakra from going berserk and turning the body's meridians into wood during cell fusion.

Using the synchronized knowledge of alchemy and herbal medicine, I created a topical medicine. It was made by crushing and mixing several herbs commonly found in the mountainous areas of the Land of Iron. When applied to the injection site, it can reduce local rejection reactions.

Three layers of insurance are in place.

On a moonless night, Hinata Chen locked himself deep inside a mine and opened a tube of interstitial cells.

After the culture medium is poured away, the cells themselves are a very small, pale white flocculent mass, almost invisible to the naked eye.

He placed it on the inside of his left forearm, made an extremely fine incision in the skin with a chakra scalpel, and inserted the cells under the skin.

The first wave of rejection came very quickly.

Within moments, the skin on the inside of my arm turned red and hot, blood vessels bulged from under the skin, and bluish lines spread upwards along my forearm, like tree roots growing under the skin.

Hinata Chen bit down on a roll of gauze, and his right hand formed a hand seal to activate the sealing plate on his chest.

A thin metal sheet was placed against his chest. After chakra was injected, it emitted a low hum. The sealing technique seeped into his arm along his meridians, pushing back the expanding Wood Release chakra.

The Resurrection Technique opened a tiny channel deep within the consciousness, intercepting the chakra of Hashirama's cells and gradually converting it into pure Yang Release chakra and a strange body energy.

Hinata Dust constantly uses his Byakugan to monitor the progress.

The Yang Release chakra and this strange bodily energy merged into the meridians and finally converged in the Byakugan.

This is……

A warm, comforting feeling filled both eyeballs until this portion of the Hashirama cells was completely drained and integrated into the body.

The white eye immediately sent a refreshing sensation throughout the body.

The gauze he was biting was soaked with saliva. Several small cuts appeared on the skin of his arm.

As dawn approached.

Hinata Chen removed the gauze from his mouth and used his right hand to support himself against the rock wall as he stood up.

I squatted all night, looked down at my left forearm, clenched my fist and then released it, and there was no abnormality in the range of motion and strength of my fingers.

Apply the palm-shaped magic to the dark spot for a final check to confirm there is no residual rejection reaction.

"Phase one is complete. We'll need to observe for a few more days to confirm that the cells won't remain dormant in the body for a period before suddenly going berserk."

……

……

The first snowfall of winter in the Land of Iron fell a few days later.

The snow started falling at dusk and hadn't stopped by the early hours of the next day.

When Hinata opened the front door early in the morning, the rooftops and roads of the town were covered with snow, and the dried-up creek was left with only a shallow indentation.

The air was free of the usual dust, leaving only the clean coolness of the snow as it fell.

He lit a charcoal fire in the furnace and started shoeing horses. The horse-drawn carts in the mining area needed to be replaced every now and then, which was the shop's most stable source of income.

The bellows made a uniform creaking sound as it was pulled, and the charcoal fire in the furnace turned from dark red to orange-yellow and then to bright white. The iron bars were heated in the fire until they softened, then taken out and placed on the anvil to be hammered.

The hammer struck the red-hot iron with a dull thud, and sparks flew onto the leather apron, burning small holes in it.

Around noon, two people walked past the shop.

Hyuga Dust didn't look up; the hammer continued to fall.

But he heard footsteps; the two people's paces were identical, and their strides were abnormally even.

These two people walk in perfect unison, their legs trained, their habits unbreakable.

He glanced up during the brief pause between hammer blows.

The two people walked past the shop and headed towards the general store.

From behind, they appeared normal, dressed casually in thick cotton robes and scarves, like traveling merchants.

However, traveling merchants would not travel in such weather; they would stay in post stations or teahouses on snowy days and wait for the roads to clear before continuing their journey.

Are they... pursuers...?
