After testing the effects of the Anti-Membrane Bandits, the next step was naturally to experiment whether or not he could use the Shadow Invading Medicine to master the void-ification technique.
The next morning, Lin Lichuan led the Soul Slasher out of District 1 and landed at an empty spot in the wilderness.
The Shadow Invading Medicine allowed the user to use void-ification while maintaining a rational state, but it was unknown whether or not the user could maintain their rationality once they were fully immersed in dealing with the void-ified doppelgänger. That was why Lin Lichuan did not choose to conduct the experiment at Soul Society's headquarters.
As for the Soul Slasher, they were his bodyguards during the experiment. When it came to personal secrets, only the Soul Slasher who were 100% loyal were trustworthy.
"Just in case, all of you just need to watch from afar." Lin Lichuan turned around and instructed Wheeze and the others.
Wheeze and the others nodded and pulled back until they were a thousand meters away from Qin Lie. They stopped and watched from afar.
Seeing this, Lin Lichuan crushed the Shadow Invading Medicine in his hand. A strange, familiar feeling instantly emerged from the depths of his body.
At the same time, a large amount of white cement-like substance gushed out of his face and formed a strange white mask with red patterns on it in the blink of an eye.
The medicine's effect lasted for a limited time, so Lin Lichuan did not have the time to carefully savor the intoxicating feeling of skyrocketing strength. He immediately withdrew his distracting thoughts and immersed his mind into the strange energy that occupied the depths of his body. Then, he slowly closed his eyes.
When he opened his eyes again, the scenery in front of him had changed dramatically.
The sandy and rocky wilderness had already disappeared, and what replaced it was an extremely strange scene.
Everywhere he looked, there were tall buildings floating in the air like balloons. There were so many of them that they stretched into the distance as if there was no end.
Right now, Lin Lichuan was standing on the side wall of a tall building. In front of him was an empty street that was hundreds of meters away. He looked like he would fall at any moment, but unexpectedly, he felt as if he was standing on solid ground. It was as if he was standing on the ground normally.
This strange feeling of direction and gravity caused him to feel a little uncomfortable.
"Haha, we have a guest."
Suddenly, a frivolous voice came from behind him. Lin Lichuan turned around and found that there was an extra person twenty meters behind him.
Perhaps it was a little inappropriate to call him a 'human' because the young man in front of him was ghastly white from head to toe. His hair, skin color, and even his clothes were all white. Only the sclera of his eyes was deep black and his pupils were golden.
Other than that, its appearance and clothes were exactly the same as Lin Lichuan's.
"No, it's a bit inappropriate to call you a guest. After all, you're the owner of this place." The doppelganger's mouth opened wide, revealing a ferocious smile as if he had seen his prey.
Lin Lichuan's eyes flashed when he heard this. He pursed his lips and carefully sized up the other party.
It was obvious that the white guy in front of him was a doppelganger created by using the Shadow Invading Medicine.
Looking at a creature that looked so similar to himself, it was really awkward.
Retracting his gaze and looking around, Lin Lichuan asked casually, "Is this my inner world?"
"You can understand it that way."
The doppelganger grinned. "Let's not talk nonsense. You came here to defeat me, right?"
"That's true."
Lin Lichuan smiled faintly. With a thought, a long sword suddenly appeared in his hand.
He carefully sensed it and unexpectedly found that the power of the Zanpakuto disappeared.
"I forgot to tell you. In this world, whether it's Shikai or Bankai, you can't use them. You can only rely on your own strength to defeat me."
The doppelganger also had a long sword in his hand. It was exactly the same as Lin Lichuan's. It showed a provocative smile at Lin Lichuan. The next second, it suddenly rushed out like a cheetah pouncing on its prey. Its speed was extremely fast. Lin Lichuan only felt a flash in front of his eyes, and the sharp blade shining with cold light had already chopped down on his head.
At that critical moment, Lin Lichuan quickly raised his sword to block the attack, barely managing to block the attack.
Clang!
After the harsh sound of metal clashing, Lin Lichuan only felt that his hand was lighter, and the doppelganger had disappeared in front of him. At the same time, the whistling sound of a sharp blade cutting through the air came from behind.
Shunpo!
The tip of the sword missed, and Lin Lichuan's figure appeared more than ten meters away in an instant, looking at the doppelganger with a dignified look.
"Flash Flower … You can also use Shunpo."
"Don't be so surprised."
The doppelganger grinned. "I am you. Of course, I can also use the ability you have. Isn't this a matter of course?"
As his voice fell, he once again attacked Lin Lichuan with a grin.
In the blink of an eye, a fierce battle broke out on the outer wall of the tall building.
As the battle progressed, Lin Lichuan found that the doppelganger didn't lie. Whether it was the strength of Reiatsu, Kendo, Shunpo, or even the Ghost Path and White Strike used from time to time in the battle, the doppelganger was on the same level as him. The only difference was the combat experience and style.
And in these two aspects, although he didn't want to admit it, he had to say that the doppelganger was much better than Lin Lichuan.
The doppelganger was like a warrior who had experienced hundreds of battles. He had an extremely keen sense of smell for fighting, and his skills were extremely proficient. His fighting style was wild and fierce, as if he was born for fighting.
As a result, not long after the battle began, Lin Lichuan fell into an absolute disadvantage.
Clang!
Clang!
Sparks flashed one after another, and the deafening sound of metal clashing continued to explode in the void, accompanied by a loud bang. It was the aftermath of the Ghost Path confrontation that blew up one building after another, splashing boulders all over the sky.
In just a short moment, Lin Lichuan's body was covered with countless wounds.
This was the first time he was in such a sorry state in a battle.
In the past battles, it wasn't that he had never encountered a difficult enemy, but relying on the strange abilities of the Zanpakuto, he didn't get injured most of the time. At most, he would overuse his Reiatsu, but he had never been covered with wounds like this.
Unfortunately, the enemy who caused this situation was his doppelganger. He didn't know if he should be proud of this.
After evading another attack with Flash Step, Lin Lichuan swung his sword horizontally and attacked the doppelganger's side abdomen.
Just as the blade was about to hit, his vision suddenly blurred.
Lin Lichuan was shocked. By the time his vision became clear again, he realized that he had returned to reality. The scenery in front of him had turned back into the wilderness with no signs of human habitation.
"Is the duration up?"
He muttered softly. Following the movement of his lips, the mask on his face cracked and fell to the ground in pieces.
"Are you alright, master?"
Fei Mei, Wheeze and the others quickly came to Lin Lichuan and asked with worried eyes.
Lin Lichuan shook his head and sighed softly, "I'm fine. It's just that mastering the void-form is much harder than I expected. It looks like I'll have to spend a lot of time."
While speaking, he looked at his body and found that all the wounds had disappeared. In their place was mental and physical exhaustion, and it was even more intense than using the Shadow Invasion Medicine normally.
"It looks like the wounds in that world won't be brought to reality, but the price is that the energy consumption will increase."
After thinking for a few seconds, Lin Lichuan bought a special nourishing and strengthening potion from the shop and drank it. When his energy and spirit had recovered to their peak, he bought another Shadow Invasion Medicine and continued to experiment.
