After being reborn with my scumbag ex-husband, I became his sister-in-law.

But when Song Ruoan heard this, her face didn't show the same confident expression as He Yunze's. She paused for a moment, then hurriedly spoke to He Yunze again:

"My husband, have you forgotten? The most precious medicinal herb in the original formula of Herbal Human World has become extinct, so it is impossible to replicate it!"

He Yunze only remembered this matter after hearing Song Ruoan's words.

He felt a pang of annoyance and looked at Song Xizhi with displeasure: "So, Song Xizhi, you did this on purpose!"

When Prince Xiu heard this, he noticed that Song Ruoan and He Yunze had said the same thing, so it seemed that they were not lying.

He pondered for a moment before walking towards Song Ruoan: "If it's impossible to replicate, then how did Pinxianglou manage to produce so many wooden artifacts?"

Song Ruoan didn't really know what was going on. During the renovation of Xianglou, she had also tried desperately to find Tianhua Ningzhi, a fragrance ingredient that had become extinct in incense recipes, but she couldn't find it at all.

So she gave up and decided to search for other common herbs to replace the effects of this medicine, just like the one made by Song Xizhi.

But in the end, she still couldn't find it.

Thinking of this, Song Ruoan carefully took out the original prescription of the Herbal Human World and presented it to Prince Xiu.

Her voice held a hint of resentment: "Song Xizhi used inferior goods to replace the extinct Tianhua Ningzhi. That's why she was able to produce wood traces even though Tianhua Ningzhi is extinct!"

"However, the herbs and plants that my husband provided to Prince Xiu in the past were unique items from more than ten years ago. Unique items depreciate over time, which is why their fragrance is comparable to the wood fragrance that my sister made by passing off inferior products."

"If I had those extinct medicinal herbs, I could create a herbal remedy that would smell much better than anything my sister makes!"

Song Ruo'an was confident because she had given Xiu Wang her "Planting the World" from over a decade ago, and it was able to match the "Wooden Trace" that Song Xizhi had just created.

Not to mention now, if she could create the "Plant and Tree World" technique on the spot, she would definitely crush Song Xizhi!

Thinking it over, she continued, "Otherwise, you get what you pay for, so why would she give it away for free? Don't you find that strange?"

As he listened, Prince Xiu took the original prescription.

The prescription looks very old, and you can smell the dampness that is unique to ancient books when you get close. There are also many creases on it, so it must be carefully preserved so that the paper will not break.

Prince Xiu carefully examined the prescription, recalling the scents of herbs and plants he had smelled before, and felt that the ingredients in the original prescription were almost identical to those herbs and plants.

Nine times out of ten, that herbal medicine was made using this prescription.

Prince Xiu then carefully showed the original formula to those around him.

After the emergence of "Wood Trace" from Pinxianglou, many incense makers tried to decipher its secret formula, but no one could find the formula so completely.

Because of this prescription, Prince Xiu was already half convinced of Song Ruoan's words: "Look, apart from the extinct Heavenly Flower Condensation Branch, whose effects I am not familiar with, the rest of the ingredients are indeed ingenious. If they are combined, they will be almost identical to that Wood Trace!"

Upon hearing this, everyone exclaimed in admiration, "Yes! We never thought of this approach before! All the ingredients are interconnected!"

"And this prescription looks like it's from over ten years ago!"

Hearing the whispers of the crowd, Song Ruoan felt a surge of pride: "Sister, now that I've revealed the prescription, I have a clear conscience!"

"If you also have a clear conscience, why not publish the recipe as well?"

Feeling her provocation, Song Xizhi simply smiled slightly at Song Ruoan: "How can you open a fragrance shop if you don't even have the most basic raw materials?"

Upon hearing this, Song Ruoan was about to retort angrily, "Do you think you can just have something that's extinct if you want it?"

But the next moment, she saw Song Xizhi calmly take out a wooden box in front of everyone.

“My formula is different from yours and doesn’t require Tianhua Ningzhi at all. But I happen to have Tianhua Ningzhi, which you said is extinct. I can give it to you.”

Song Ruoan's eyes widened in an instant.

Song Xizhi raised his eyebrows at her, then gently opened the wooden box, and a delicate fragrance wafted into everyone's noses.

"With just your recipe, it's impossible to prove that the wood I sell is the same as your incense, let alone that it's plagiarism."

"I happen to have the extinct herb you mentioned, and I'm willing to give it to you. So, you can make it according to the recipe, and then let everyone come and taste and compare it to see if it's from the same source, or if I've used inferior ingredients and stolen your recipe. How about that?"

Song Xizhi's words surprised everyone present.

Song Ruoan was speechless for a moment.

They never expected that the miraculous, extinct herb that Song Ruoan had described could be produced so easily by Song Xizhi.

At this moment, Song Ruoan pursed her lips, her gaze fixed on Song Xizhi's smiling face, her brain racing, feeling something strange for no reason.

Song Xizhi had some rare herbs that were no longer available, and he was willing to give them to her.

So all the wooden traces she made before were made from extinct herbs?

This could explain why Song Xizhi was able to produce so many wooden traces over time.

Such a precious thing, obtaining even one is already extremely rare in the world, so how could she make so many wooden footprints and then casually give them away?

But Song Xizhi also said that he had never used this extinct herb at all...

Song Ruoan thought and thought, but her mind was a complete mess, and she couldn't guess what Song Xizhi was thinking at all.

A sense of unease suddenly arose in her heart, and she took a few steps back, about to refuse: "Who knows if what you're taking out right now is the extinct Heavenly Flower Branch?"

After she finished speaking, everyone heard Prince Ning's voice with great interest: "I can testify that what Boss Song has in his hands is indeed the extinct Tianhua Ningzhi."

He walked up to the wooden box, smiled, and held up the Heavenly Essence Branch, displaying it to everyone: "Because this extinct Heavenly Essence Branch belongs to me."

"I have treasured this for a long time, and it was just delivered to Boss Song."

Song Xizhi raised an eyebrow, his eyes filled with amusement as he looked at Song Ruoan: "Oh? You're saying this original formula is yours? But you don't even recognize Tianhua Ningzhi?"

Song Ruoan choked for a moment, then hurriedly said, "I know! Of course I know! It's just that you were the one who took it out just now, and I was afraid you had tampered with it."

He Yunze was very angry at Song Xizhi's questioning. His aggressive and pressing manner made it seem as if he was waiting to see Ruo An make a fool of herself!

She looks down on people like that, thinking that Ruo'an has no idea how to make incense, which is why she repeatedly forced her to make incense in front of everyone.

He Yunze almost sneered.

It's likely that once Ruo'an produces the incense, Song Xizhi will realize what it means to bring shame upon oneself.

"Since this herb was brought by His Highness Prince Ning, then there's no problem. Ruo'an, now prepare it for her and show her!"

Upon hearing this, Song Ruoan looked up at Song Xizhi and took the wooden box from Song Xizhi's hand: "Okay, I'll make one for you to see."

"Once I create the Herbal World, I would appreciate Your Highness Prince Ning's careful evaluation to see if my sister's wood traces are the same as the ancient formula I have used for the past ten years."

"If they are the same, then it proves that my sister stole my recipe!"
