Lin Liya naturally knew what Lin Liwen was thinking, and she also wanted to know the reason for this at that time, but after looking for a long time, she didn't see any useful news.

"Now let's not care why the other party was confused by this golden cicada's shell, we now know that the person who wanted his mother to die was not only the old emperor, but also other forces, so the emperor will let it go first, but we can investigate and investigate this other force first, and we can find an opportunity to find these people to collect some interest first."

Lin Qiya's eyes revealed this anger, Lin Qiwen was a little frightened by Lin Qiya's eyes, but if you think about it carefully, those people can be regarded as killing their father's enemies, and it is nothing to ask them to collect some interest.

"Don't worry, we're not fledgling now, but we have a goal now, step by step, and one day we will take revenge." Although Lin Shuwen felt that it was nothing to collect some interest, he didn't want this matter to be done by Lin Qiya, so he could only slow Lin Qiya's emotions first.

"That's right! Take it easy. Lin Qiya didn't know that Lin Qiwen was procrastinating, she just felt that what Lin Wenwen said was right, this matter couldn't be rushed.

Then Lin Qiya didn't know that Lin Qiwen actually secretly learned kung fu from Yu Zimo from this day, and even established an existence like Yu Zimo with the help of Yu Zimo.

Of course, they wouldn't think about killing the current emperor, after all, they couldn't afford the name of rebellion, so they could only use their way to get the emperor to rehabilitate his father.

Of course, this is all an afterthought, whether it is rehabilitation, or dealing with those who are tracking, they are still too small now.

Speaking of Canghua Pond, he personally returned to Jinyi City after getting the refining method of refined salt and the production method of firecrackers.

After all, these two things are too important, and he is not at ease when they are transmitted back to Jinyi City in any way.

No one knows when the emperor returned to Jinyi City, anyway, the emperor had already returned when Canghuachi arrived in Jinyi City.

What Lin Qiya gave, the emperor immediately let people try it after he got it.

The refining of refined salt can see the effect immediately, and Grandpa An has already prepared the salt mine, waiting for Lin Xuya's way to experiment.

"Charcoal? Cotton cloth? Are these also specifically marked as important things? The emperor looked at what Lin Qiya wrote, although he didn't understand how the charcoal and cotton cloth and purified refined salt helped, but he still asked Gonggong An to prepare according to what was written on it.

Next, Father-in-law An and Canghuachi started together, and followed the steps written by Lin Yuya step by step.

The emperor watched from the sidelines, and from time to time pointed out some problems against the steps written by Lin Qiya.

The salt ore is ground to a pulverized and placed in a large basin, then water is added, and after thorough stirring, the water is filtered through a cotton cloth.

Because this step was very important for Lin Qiya, Gonggong An and Canghuachi filtered it many times with four layers of cotton cloth according to the requirements, until the original brown water turned light red.

This step only removes the impurities, and there is still a certain toxicity in this water.

So Canghuachi knocked the charcoal to crush again, he knew the role of charcoal, Lin Qiya once made a filter and added charcoal.

Wrap the charcoal in cotton cloth, then compact, then put it in a funnel, and press it again so that there is no gap between the charcoal bag and the funnel.

After that, slowly put the previously filtered water into the funnel.

Little by little, the water flows out through the funnel, slowly, but filtered well.

The original light red water slowly changed color again, forming a pale cyan color, which is a sign that the toxicity in the water has been removed.
