Wang Delong's family members left with the interrogators in a nervous mood and were taken to different rooms for questioning.

Other guards walked out of the chamber of commerce to explore several chambers of commerce that competed with Red Rose.

"Sigh... let's go back to our room to rest first. We don't have enough information right now and can't draw a conclusion." Yu Yi sighed.

"Okay, Brother Yu."

Seeing this, Wang Debao hurriedly stepped forward and said, "Sir, we have prepared rooms in the Chamber of Commerce. Please come with me."

"Um."

The Red Rose Chamber of Commerce covers a huge area. Although it is not a top-tier chamber of commerce, it has all kinds of supporting facilities.

There are many warehouses for storing supplies, trading squares, schools where guards train, auction houses, chambers of commerce and hotels, etc.

Yu Yi was currently in the senior suite of the Red Rose Hotel.

This kind of suite is somewhat similar to the presidential suite on earth. It is very luxuriously decorated and has a living room, conference room, bedroom, etc.

Jiang Yuyao and Su Kexin were also in Yu Yi's suite.

The little girl is playing with various decorations out of boredom.

Su Kexin was sitting on the sofa in an orderly manner. She was not as casual as the saint.

"Brother Yu, why don't we go out and play? I haven't visited Nantacheng yet?"

"It's getting late today. If we go out tomorrow, I'm afraid Wang Delong's incident won't be able to be investigated in a day or two. There's no rush."

"Hehe... Brother Yu is the best." Jiang Yuyao's eyes crescent moon.

"Kexin, what are you thinking about? Frowning?"

"I'm thinking about Wang Delong's case, and I don't know who is the murderer?" Su Kexin said with a wrinkled face.

Jiang Yuyao shook her head helplessly, "The results of the autopsy, the interrogation results of the family members, and the interrogation results of the maids and guards on duty that day have not been released."

"No matter how much you think about it, it's useless. It's better to free your mind and think about where to go tomorrow."

Wang Delong's family members, the maids, guards, and servants responsible for taking care of him in the chamber of commerce's house total at least several hundred people.

It would be impossible to investigate them one by one in just a few days.

Yu Yi looked at the lights of Wanjia that were gradually lighting up outside the window, and was thinking to himself that Wang Delong's incident was by no means as simple as a vendetta on the surface.

I'm afraid it also involves some internal issues within the Black Lotus Sect.

He wouldn't be surprised if someone said that someone sent from the headquarters killed Wang Delong and caused the current situation.

Not long after, the hotel waiter brought a sumptuous dinner.

The door is closed.

Jiang Yuyao cheered and rushed forward, trying to grab the food.

Yu Yi grabbed the little girl's back collar, slipped her back to her side, and threw her on the sofa.

"Brother Yu, what are you doing?" Jiang Yuyao kicked her calves pitifully in mid-air.

Yu Yi hated the iron and said: "Idiot... The Red Rose Chamber of Commerce is surrounded by dangers, and the enemy and we are unknown. How can we rashly touch the food they sent?"

"Huh? No way? Even if someone has evil intentions, he shouldn't poison him directly. It will be too easy to detect."

"The mastermind behind the scenes poisoned us to death in the Chamber of Commerce. Isn't he digging his own grave?"

Jiang Yuyao got up from the sofa in shock and retorted.

Yu Yi shook his head, "People in the Chamber of Commerce may not be so bold. What if the enemy comes from outside the Chamber of Commerce?"

"Oh...that's what Brother Yu said."

Jiang Yuyao nodded lightly and turned to look at Su Kexin, "Kexin, go check whether the food is poisonous?"

"Yeah." Su Kexin stood up and came to the dining table.

She took out a silver needle and poked it around on each plate.

Yu Yi looked at it and shook his head. The silver needle poison testing method was considered backward in ancient China. He didn't expect that people still use it in other worlds.

Tianyuan Continent has many secret spells to kill people, and there are also many combinations of poisons that cannot be detected with a silver needle.

Spells require a medium, and almost no one puts spells on dishes, so they can be easily detected.

Relatively speaking, combined poisons are difficult to detect.

Several non-toxic and unrelated plants combined together can turn into potent poisons.

Many combination poisons have no solution.

Yu Yi interrupted Su Kexin's childish behavior and said, "Don't try it. You can't test it with a silver needle. No one would be so stupid as to use ordinary poison to poison. If you want to do it, you have to use a combination of poisons."

"Wow... the silver needle has turned black." Jiang Yuyao, who was watching the excitement, suddenly exclaimed.

Yu Yi: "..."

"Brother Yu, didn't you say you can't try it out?" The little girl blinked her big eyes and looked at him cutely.

Yu Yi's face was as black as the bottom of a pot.

He didn't expect that someone would be so stupid as to poison the food.

Even if it's poison, it's still an ordinary poison, the kind that even a silver needle can detect.

The way Su Kexin looked at her Lord God was also strange.

Yuyi dug his toes into the ground, wanting to find a crack in the ground and crawl in.

He immediately became furious.

Which stupid thief is playing tricks on him?

After Jiang Yuyao laughed, she was also furious.

The people behind the scenes are simply lawless.

"Lu Sheng, come in."

"Your Highness the Saint, what do you want from your subordinates?"

Jiang Yuyao's pretty face was slightly angry. She put one hand on her hips and pointed at the silver needle in Su Kexin's hand with the other, and shouted softly: "See for yourself!"

Lu Sheng's face changed drastically, and he hurriedly held up his hands and said: "Your Highness the Saint, it was my subordinate's mistake. I immediately ordered people to blockade the hotel and arrest all the people in the hotel for torture."

Something happened to the saint here, and not only him, but even his family had to die.

Yu Yi promptly added, "Lu Sheng, don't harm innocent people. Indiscriminate use of torture will have bad effects.

You immediately send a message back to the headquarters and ask Leader Jiang to secretly send a few experts here, remember not to let the Holy Son and the Ninth Captain discover it."

"Yes, Mr. Special Envoy." Lu Sheng bowed and bowed before exiting the suite.

Yu Yi rubbed his temples, "Oh, I was really unexpected. Things are getting more and more complicated."

"Brother Yu, I'm hungry." Jiang Yuyao looked pitiful and cute.

"Don't you have dry food in your Yuan Ring? Let's deal with it first, and then go shopping tomorrow for a big meal."

Yu Yi waved his hand carelessly.

"Oh alright."

Jiang Yuyao sighed in disappointment. She wanted her god to take her out to play and taste the delicacies of Nantacheng.

After a while, the whole hotel was in a state of uproar.

The Holy Son, the Ninth Regiment Leader and others gathered in Yu Yi's room.

"What's wrong?"

Yu Yi looked at the large group of people in the room with confusion.

Lu Xiao's face turned ugly as he said, "Our food has also been poisoned. We are asking our subordinates to cooperate with Lu Sheng in arresting the hotel staff."

Candace nodded, "Mine too."

"Why didn't I poison you to death?" Jiang Yuyao whispered.

Yu Yi glared at his saint, saying not to engage in internal strife at this time.

Lu Sheng walked into the room with an ugly expression on his face.

"Your Highness the Saint, ladies and gentlemen, several guard captains and I used hypnosis to interrogate the waiters who delivered the food, but they didn't know anything about it.

When they arrived at the hotel's back kitchen, one of the chefs had already committed suicide by taking pills.

It was the chef who administered the poison, and the others are still under interrogation.

The subordinates speculated that it was unlikely that the hotel staff knew about it.

The dead chef and the contacts behind him are the key."

When everyone heard this, their faces turned ugly.

The people behind it were very cautious, and the chef who committed suicide by poisoning was probably just a scapegoat.
