I stared at Xiao Anzi deadly, "Are you sure you're not mistaken?" Several highnesses have eaten the same thing, but only the four princes have been poisoned? ”

When Xiao Anzi saw me asking him like this, he couldn't help but hang his head and think for a while. It's just that he finally said, "Yes!" Master, the slave guarantees with his life, and he will never be mistaken! ”

"Are the meals still there?" I glanced at Xiao Anzi and asked.

Since it is used very little, it will naturally not be used up.

Sure enough, Xiao Anzi lowered his head and said respectfully, "Back to the master, because His Royal Highness the Fourth Prince had only used the food for a while at that time, something happened to him, so the slave was worried that there was something wrong with those meals." So I kept an eye on it early, put everything away, and stored it. ”

I listened, nodded, and praised Xiao Anzi, "You go, bring all those meals." Including the tableware and handkerchiefs used by His Royal Highnesses, none of them can be let go. ”

"Yes, master."

Xiao Anzi got the order, and only walked out two steps. But I didn't think something was right.

If there is a problem with eating, no matter how much Xiao Anzi keeps an eye on it, those things are afraid that they will be thrown down by someone earlier, how can they leave a handle?

The only possibility is that there is no problem with those things at all!

So, I couldn't help but say, "Wait! In addition to meals, bring all the things that His Royal Highness the Four Princes have used in the past few days. The clothes you wear and the incense you burn can't be let go. ”

"Yes, master!"

……

Xiao Anzi's movements were extremely neat, and after only waiting for a moment, he took everything that should have been brought.

Today's meals, cutlery, handkerchiefs, clothes worn in the past few days, spices used, teacups drunk, and even pen, ink, paper, and inkstones were all brought over.

Everything was as I expected, and Dr. Luo didn't find any problems with the meal.

And the most strange thing for me is that even the things he used didn't find anything unusual.

"Xiao Anzi, is this all the things that His Royal Highness the Fourth Prince has come into contact with in the past few days?" I walked over to Yun Yan and sat down, holding his hand carefully, feeling extremely distressed.

"Back to the master, except for the bed where His Highness slept on, the rest are here."

I listened and nodded slightly, "Since that's the case, I'll bother Brother Russell to help me take a second look." ”

As soon as the words fell, I suddenly noticed that there was something like ink on Yun Yan's fingers. Light gray, not thick, but on Yunyan's white fingers, it looks unusually clear.

Odd......

Although Yun Yan has always loved to practice calligraphy, he also loves cleanliness very much. When I practice calligraphy on weekdays, I will inevitably get ink on my hands. However, at any time, he would wash the dirt clean.

According to Xiao Anzi, Yun Yan had an accident while eating, and he would definitely wash his hands well before eating.

This black inky thing...... What is it?

Thinking of this, I felt more and more guilty.

Damn it!

I knew that today I should not rely on the willfulness of the children and let them eat by themselves. If I had eaten with them earlier, I would have been able to see what had happened even if something had gone wrong! And not like now, everything is confused.

Looking at Yun Yan's weak breathing, I sighed deeply. Carefully put his hand down, and walked towards Imperial Doctor Luo.

At this moment, Imperial Doctor Luo is carefully inspecting every object, and his serious appearance is distressing.
