Gu Qiqi lowered her eyes and sighed here.

Wu Shijiu looked around curiously.

What she usually goes to is a tall and luxurious place, and it is the first time she has come to this old house that has been covered with dust for many years.

When she saw the dried corpse, she instinctively shrank to Gu Qiqi.

Fortunately, Gu Qiqi did not push her away this time, but carefully pulled her by her side to remind her to pay attention to the glass fragments on the ground.

Wu Shijiu felt warm in his heart, as if a small sun had risen.

Looking back on the little movements of jumping into the window with Gu Qiqi just now, I feel an unparalleled sweet and happy life.

She thought to herself in her heart that after the adventure with Mr. Ye tonight, they should have had a rare common experience and a common little secret, and in the future...

Just as he was thinking, he suddenly saw Gu Qiqi squatting down, picking up a piece of glass fragments, and looking at it in the moonlight.

Wu Shijiu also quickly squatted down: "Young Master Ye, are you going to take away the things from that year and worship the senior?"

Gu Qiqi answered the question irrelevantly: "Your Highness, can you smell it. This is the residual drug on the test tube fragments?"

Wu Shijiu closed his eyes and concentrated his feelings for a moment, and spoke: "Potassium permanganate, glycerin, alcohol, safflower, salvia miltiorrhiza... It's so mixed, what medicine should I use? How can glycerin be mixed with potassium permanganate? This must explode! Alas, seniors are too careless!"

Gu Qiqi said calmly, "How much do you think the potassium permanganate and glycerin can be contained in such a small test tube with a dose of less than 100ml?"

"Well... there shouldn't be much! Potassium permanganate has a strong smell. If it exceeds 2ML, the taste will be quite pungent, and the color is also dark purple and red, which is particularly obvious. You will definitely be discovered. You can't wait for the explosion at all..." Wu Shijiu said, and finally realized something was wrong and looked up suddenly, "Mr. Ye, do you suspect that the explosion back then was not the cause of potassium permanganate and glycerin?"

Gu Qiqi nodded: "This dose of potassium permanganate and glycerol will definitely not cause much explosion, at most it starts with a small spark. There is another reason for the explosion!"

The reason for the explosion that Feng Yangchu mentioned was potassium permanganate and glycerol.

Because in this prescription, you need to add trace amounts of potassium permanganate, then only if you are mixed with glycerol, you may explode.

Glycerin is colorless and odorless, and it is not easy to be found when applied to the test tube wall in advance.

When potassium permanganate is poured in, it will explode!

Feng Yangchu has been depressed for so many years and blames himself for his guilt, but regrets that he did not have a good test for the test tube before the competition.

Whether it was framed by someone to apply glycerin on the test tube or the accident that the test tube contained glycerin, it was his fault. It was his failure to check carefully, which led to the death of his senior brother!

He regretted it for more than ten years!

However, after a live inspection, Gu Qiqi keenly discovered that a 100ml test tube and trace amount of potassium permanganate were not enough to cause a life-threatening explosion.

This is strange...

Wu Shijiu was also frowned when she said it, and said in confusion: "What else can be the reason? Unless there are still some drug ingredients left in it... I'll smell it again..."
