No, where does this portal come from?

"On the contrary, if I kill you... the head of the Ubuyashiki family cannot take revenge on me later!" The samurai looked at the head of the Ubuyashiki family.

Just as the head of the Ubuyashiki family was about to speak, Lin Yan suddenly waved his hand back, stopping the words that were about to come out of Ubuyashiki's mouth.

"Don't worry, I can save you if I say I can."

"If I say I can chop this scum in half... I can chop them in half!" Lin Yan turned his head slightly, his pink eyes tinged with a hint of blood, which made the head of the Ubuyashiki family shudder.

After a brief silence, the head of the Ubuyashiki family took a deep breath and stepped back. "Since the doctor has said so, I will not stop you! But please, doctor, please ensure your own safety! Don't be so stubborn!"

Without answering the head of the Ubuyashiki family, Lin Yan walked out quietly.

The warrior stared at Lin Yan and used his hands to repel the warriors who followed him. He shouted loudly, "I want to fight him one-on-one. Stay away and don't get in the way."

As the area at the entrance was cleared, Lin Yan and the warrior also stood on both sides of the open space.

"My name is Yamamoto Benjiro! The style I use is Tenchi Hiryu-ryu!"

"My name is Lin Yan, and I use the Yidao-Looking-like-Nima Style."

"...Baka!!!" Yamamoto Jiro roared and drew his sword suddenly!

The drawn scabbard was not thrown away, but was held in the left hand and thrown out as a hidden weapon!

The sound of a blade breaking through the air suddenly tore through the dead silence in the field.

The moment Yamamoto Jiro threw out the scabbard, Lin Yan retreated half a step and twisted his waist to the side.

The moment the scabbard flew past his throat, his right hand suddenly shot out and grabbed the end of the scabbard!

The moment he grasped the end of the scabbard, Lin Yan suddenly exerted force with his palm, and the green bamboo scabbard was crushed in an instant!

Then, with a flip of his wrist, the fragments were thrown out with the force!

Fragments blasted out!

Swah——

The scabbard fragments that were thrown back were like dense arrows shooting out, rushing towards Yamamoto Jiro at a rapid speed!

"A mere trifle!" Yamamoto grinned and swung his sword, but his wooden clogs drew a cloud of dust on the bluestone slab.

The moment the fragments fell, he stomped his left foot on the ground.

The figure seven steps away suddenly became blurred!

The next second, the blade had already cut into Lin Yan's carotid artery.

The warriors watching the battle clutched the cloth on their knees...

Shrink the earth!

It must be Shukuchi!

Shrinking the Earth, a real-life kendo footwork technique.

It can make people feel visually that the target is attacking suddenly in an instant.

Facing the sudden attack from Yamamoto Jiro, Lin Yan showed no panic at all.

next moment!

The solid figure suddenly disappeared!

——Cang Lang!!

The clear sound of a knife pierced everyone's ears.

look again...

Yamamoto Benro, who had been charging forward with his sword raised, suddenly stopped...

puff-

A line of blood appeared in the torn flesh.

Then... the whole body split in two!

Blood is spurting!

Chapter 40: The 'Medicine' is Only 70% Complete

Everything happens in a split second.

The crowd didn't even see what happened between the two men. They only saw a flash of a knife, and Yamamoto Jiro was cut in half and fell to the ground, without a sound.

After doing all this, Lin Yan walked back to the yard without looking back and threw the long sword that was still dripping with blood to the warrior.

Seeing that Lin Yan ended the battle in just a moment, the head of the Ubuyashiki family, who had been worried just now, finally breathed a sigh of relief.

"You are all witnesses! You have all witnessed the glory of the samurai." The old patriarch's powerful voice echoed through the streets. "Now, I would like to ask you to bring Yamamoto's remains back to his homeland for burial."

After saying that, Ubuyashiki ordered Hirasa to close the door, and without looking back, he led Lin Yan towards the room where Muzan was.

As he walked, he also introduced the current situation of Muzan to Lin Yan, as if the bloody scene just now had never happened.

"Doctor, Muzan's health has indeed become weaker recently..." Ubuyashiki said as he walked: "Two years ago, he could still run a little, but now he can only move around in the house.

And if he moves a little more, his face will turn pale and he will be out of breath..." At this point, Ubuyashiki stopped in front of the door, his old face full of helplessness and guilt.

Lin Yan looked at the closed wooden door in front of him, and gently grasped the door handle with his fingers: "Don't worry, I will definitely do what I promised you."

"However, before that, I heard that there is a doctor who has been treating your Excellency wholeheartedly in recent years..." Lin Yan said thoughtfully.

Hearing this, Ubuyashiki thought that Lin Yan didn’t want to treat the same patient with other doctors, so he quickly promised Lin Yan: “Doctor, don’t worry!

If your method can truly cure Wuzan, I will absolutely kick all other doctors out! Only you will be left to heal Wuzan! This is the minimum respect for doctors!"

"You misunderstood." Lin Yan chuckled, "The thing I care least about is co-treating patients."

"I told you this just because I wanted to meet the doctor and discuss my condition and the next treatment plan with him." Lin Yan lied without hesitation.

Discussing the condition and treatment is complete nonsense!

He called the doctor over just to ask about the progress of the research on the medicine that could cure death.

As for Lin Yan's treatment plan, it was just to teach Muzan some basic knowledge about ripple qigong.

Ripple Qigong has the effect of curing injuries and prolonging life. Although Lin Yan does not know whether Ripple Qigong can cure congenital diseases, it is very likely that it can improve them.

Therefore, he never thought of giving Muzan medicine or trying to treat his illness from the beginning, but he had been thinking about the "ghost transformation" medicine from beginning to end.

In Lin Yan's opinion, the scumbag boss who had been cured was still scumbag.

This kind of person has no personal charm at all.

Speaking of charm, it is only the identity and ability of the "Ghost King".

Arrogant, isolated, selfish, paranoid, lacking empathy, and uncontrollable emotions.

His power is based on tyranny, and he is extremely selfish, treating his subordinates as disposable. He appears powerful on the surface, but in fact he is filled with fear of death in his heart.

When faced with setbacks, he took his anger out on his subordinates. After losing control of his emotions, he was eager to eliminate Tanjiro and exposed his whereabouts.

This existence, which combines so many shortcomings, can be summed up in one word: "scrap".

When the head of the Ubuyashiki family heard that he was going to discuss Muzan's condition with other doctors, he trusted Lin Yan even more.

Discuss the condition with each other, research and develop treatment plans, and diagnose the same patient together with other doctors, rather than using the excuse of protecting the "honor of the doctor" to monopolize patient resources.

This is what a doctor should be like!

"Doctor! I'll call another doctor right away! Please wait!" After saying this, Ubuyashiki winked at Hirasa who was standing beside him: "Hirasa!"

"Understood! Patriarch!" Pingcao quickly retreated.

Soon, a thin and gentle man wearing doctor's clothes was brought up by Pingcao.

When he saw the head of the Ubuyashiki family, he quickly bowed respectfully: "Head of the family..."

"Well! Kuronuma, you're here just in time!" Ubuyashiki led Kuronuma to Lin Yan and introduced him attentively, "Kuronuma, this is the new doctor. Like you, he's here to treat Muzan.

He now wants to discuss with you about Muzan's condition and the subsequent treatment plan. Please cooperate."

"Yes! Patriarch!" Heinuma said, bowing slightly to Lin Yan.

While Hei Nuo was bowing, Lin Yan looked Hei Nuo up and down.

He was short and thin, gentle, with a somewhat timid look on his face...

This was Lin Yan's first impression of him.

When Heinuma stood up, Lin Yan naturally withdrew his gaze and put on a smile on his face: "Mr. Heinuma, from now on, we two will work together."

"It's a great honor." Kuronuma said humbly.

After that, the two of them opened the door and walked into the room.

The head of the Ubuyashiki family was very tactful and did not follow them in, but left a private space for the two.

The reason why he was able to grow his business so big was that he understood the principle of specialization and he knew better than to get involved in things he did not understand.

Since both doctors were there, there was nothing for him to do, and there was no need for him to go in.

There were no candles lit in the room, and the enclosed air smelled a little foul.

The simple room had no decorations at all, only a few cabinets and a low table for dining.

The two of them stood in the dim room, like two black shadows with unclear faces.

Neither of them took the lead and walked towards Muzan's room, but stood by the door.

With a slightly strained breath, Lin Yan turned to look at Kuronuma beside him. "I heard that Mr. Kuronuma has been researching a drug that can cure Muzan in recent years. I wonder how far along he is?"

"To be honest, I do have some unique insights into pharmacology and medical techniques, and I think I might be able to help."

Hearing Lin Yan's question, Hei Nuo shook his head and sighed: "Alas! It's really embarrassing to say..."

"After several years of preparation, the research and development of the drug has only reached about 70% of its progress.

Although I am confident that I can fully prepare the potion within two years, after observing him for the past few days, I have discovered that Master Muzan's body doesn't seem to be able to hold out for that time...

If I can't speed up the completion of the potion in the next six months, then I can only give Master Wuzan the unfinished medicine and try to see if I can save him."

"Seventy percent...?" Hearing Hei Nuo say that the research progress was only seventy percent, Lin Yan narrowed his eyes slightly and muttered to himself.

No wonder the pharmacist in the plot gave Muzan a defective potion.

It turns out that until half a year before Muzan's death, the research progress had only reached about 70%... there was still 30% left before the drug was fully developed.

"It seems that in a normal plot, the pharmacist only completed the complete concept and direction of the potion's effects in the end, and did not have time to help Muzan find the last medicinal ingredient..."

"And the imagined blue spider lily... is the final piece to complete the puzzle!"

Chapter 41: Waiting is a compulsory course for hunters

In the dim room, Lin Yan narrowed his eyes and fell into thought.

Should I wait quietly for the development of the medicine?

Or maybe find a way to help improve the potion...

Two completely different ideas flashed through his mind, but Lin Yan quickly gave up the idea of ​​helping to improve it.

Before coming into contact with the Ghost Transformation Potion, it is not clear whether the Ghost Transformation Potion can be improved using empowerment points.

If external forces are applied to the medicine without authorization, it is likely to disrupt the original research plan of the medicine and thus destroy the effect of the medicine itself.

That would be more trouble than gain.

Still according to the original plan, I only need to use the ripples in my daily life to temporarily extend Muzan's lifespan and wait for the medicine to be developed...

Thinking of this, Lin Yan turned around and said politely to Heinuma, "Doctor Heinuma, if there's anything I can do for you in your research on medicine in the future, please feel free to ask for my help."

...I don't know anything anyway.

Facing Lin Yan's politeness, Hei Nuo seemed very excited: "It is an honor to receive your help! Please take care of me in the future!"

"Well...please take care of me..." Lin Yan smiled awkwardly.

He has forgotten that foreigners don't know how to be polite, and he really wants to ask you for help.

"By the way! I don't know your name yet?" Heinuma asked curiously.

Lin Yan also did not hide his feelings and uttered his name lightly: "Lin Yan."
