I continued my thoughts even at the moment. My heart was pounding like it was going to explode.

Then one more question arose. If Gerald’s the regressor, the time traveler I thought he’d be, why did he help me make the Nisephor medicine?

No. Rather, those who helped us had knowledge far ahead of us.

How could he do that?

Obviously, before I went back, the Nisephor drug had not been developed. My mind was all over the place.

Gerald looked at me as if he knew I was looking at him.

I couldn’t read any of the answers I wanted from his eyes.

“Lulu?”

The voice calling me was soft.

“Why are you looking at me like that? What’s wrong with you?”

Gerald grabbed me with a worried look.

“Lulu!”

He pressed me for an answer. I reached out and grabbed Gerald’s shoulder.

More than anything else, the only thing I’ve ever wanted to ask.

Why did you do that to me?

Why did you turn away from me?

Why did you make me feel lonely?

My lips quivered. However, I was aware that these questions were not appropriate to bring up now. This was my dad’s bedroom.

And my dad was still unconscious.

I grabbed Gerald by the wrist. For some reason, I was expecting to find out all the answers this time.

If my guess was wrong, my sudden doubt would have come from useless expectations and delusions.

“It’s nothing, Gerald.”

Only then did Gerald breathe a sigh of relief. I knew that everyone in the bedroom was watching me.

“I need to rest a little.”

I needed time to organize my thoughts, too.

“Well, I’ll be here, so take a rest,” my grandaunt said.

“Yes, Grandaunt”

I hugged my grandaunt tightly and kissed her on the cheek. In return, she patted me on the back.

Whatever the truth was, my grandaunt’s hands were still warm.

Louella left to rest for a while. Gerald hesitated then followed.

Only Billiers and Louella’s aunt, Unelli, remained in the bedroom. The doctor was also away for a while. Billiers glanced at Unelli.

Unelli had taught Billiers in the past as an advisor to the Nippler Academy.

Billiers remembered all of Unelli’s lessons. The class was always groundbreaking.

Unelli knew how to make special use of ordinary grasses that were easily accessible.

She also taught her students how to use poisonous weeds as medicinal herbs and vice versa.

Unelli’s class had a great influence on Billiers’ preparation of Nisephor drugs.

“It’s been a long time since I saw you, teacher.”

“Billiers, it’s been a long time since we met. I didn’t expect to see you like this.”

It was the first time the two had met since Unelli resigned as an adviser.

“Me, too. I didn’t expect to see you here.”

“You did an excellent job. You will save many lives.”

“It’s all thanks to you, my teacher. Without your teaching, I wouldn’t be who I am now.”

“Well, it’s all your hard work, not my teaching.”

Unelli smiled softly.

“But I guess I still have a long way to go.”

Billiers turned his head and stared at the Grand Duke of Leander, who had yet to wake up. Arthur was asleep with a pale face.

Inside him, Nisephor and the medication would be fighting. In Billiers’ eyes, it seemed to be in sight.

“What makes you think so?”

“……Aftermath. Nisephor leaves a mark.” Billiers spoke in a wretched, wistful voice.

“Aftermath. No medicine can be perfect.”

“Yes…”

“But.” Unelli continued.

“There’s a way for the medicine to be perfect.”

Billiers stared at Unelli with a startled look.

“There’s no shortage of your medicine, Billiers. I also read your paper. In my view, there was nothing lacking in your medicine. Except for one thing.”

“What is it?”

His heart started beating fast.

He felt like Unelli would teach him the answer that Billiers couldn’t find. Unelli was also an outstanding medical scientist.

There was also a history of in-depth research on the body.

“Your medicine is based on mana stone. But mana stone is not a substance that can mix well with the human body. It doesn’t blend well with other ingredients.”

“……That’s right.”

“I think that was the reason behind why it leaves aftereffects.”

“Are you saying that the body isn’t able to absorb all the medicine?”

“Yes, that’s it.”

“Then…” He paused. “What method should I use?”
