He used a spoon to feed Ayako two mouthfuls to let her taste it, and Tang Ze cleaned up the rest.

After dinner, the two went out to see an opera and then leisurely returned home.

Although Tang Ze came up with a breakthrough clue through Ayako's inadvertent reminder, he was not so impatient that he ignored his life and plunged into work.

Moreover, this verification requires a huge workload and cannot be completed in a short time.

The next morning, Tang Ze did not go to work early, but rested at home for a while after dinner and did not go out until eight o'clock.

His destination was not the Metropolitan Police Department, but the largest fertilizer store in Tokyo.

That’s right, Ayako’s words yesterday reminded him of an important piece of information, or rather, helped him get out of his misunderstanding.

Glycerin can be easily obtained in enemas, and although pure "acid" is not so easy to obtain, some things contain "acid" and can achieve the same effect.

Gardening fertilizers are the most common substances that may contain the element "acid".

With a wave of his hand, Tang Ze bought all the fertilizers on the market and asked someone to put them in the trunk of his bicycle.

Fortunately, although there was a lot of fertilizer, they were all in small packages, and Tang Ze's trunk could fit a whole package. Otherwise, he would have to ask someone to drive a truck to deliver it to the research institute.

However, when he came to the testing department carrying a large amount of fertilizer, he still caused wailing.

After all, the previous workload was enough to devastate them, but they didn't expect to have to do it all over again this time, and the workload would be even greater.

After all, this time we are mixing fertilizer and enema together to see if they can match the magazine at the crime scene.

Just thinking about that huge combination makes everyone's scalp tingle.

"Okay, I know the workload is heavy this time, so I'll give you overtime pay."

Tang Ze held the pot of flowers and smiled, "Thank you for your hard work. Now go to my car and bring up the fertilizer. And bring up some food and drinks. It's my treat."

After hearing Tang Ze's double encouragement, the researchers' faces finally looked better.

But when they thought of the terrifying workload, everyone couldn't help but sigh.

After Tang Ze became a hands-off boss, he increasingly felt that it was a wise choice for him to promote the establishment of "Kesouyan" at that time.
