Chu Xixuan stood up irritably and said, "Ridiculous, it's really too ridiculous! I think you are really crazy!" Then he was about to leave.

"Yes, I'm crazy. The head of the Lan family is my motivation to live! But... Chu Xixuan, don't you want to know the truth? Don't you want to know why Lan Ziye is so obsessed with the Essence Stone? You have to know that in this era, Essence Stones don't have much use for humans!" Su Muhan stood up and shouted at Chu Xixuan's back, "If Lan Ziye is the missing head of the Lan family, then there is only one possibility for her desperately searching for the Essence Stone: she wants to go back!"

Go back? Go back to where? Three thousand years ago? Chu Xixuan's heart felt like it was twisted violently, aching. He ignored Su Muhan and strode out of the Dark Night Cafe.

Back at the suburban villa, he looked up and saw the light in the study was on. It must be Lan Ziye using his study again. Ever since he started tutoring Lan Ziye, Lan Ziye and he had been sharing a study.

Chu Xixuan went up to the study on the second floor, pushed the door open, and saw Lan Ziye reading a book seriously.

"You're back? There are a few points of knowledge that I don't quite understand!" Lan Ziye said without even raising his head.

Chu Xixuan closed his eyes. He remembered Chu Xining once said that Lan Ziye had no interest in studying. She would just sleep on the table during class like Chu Xining. Now she was working so hard, was it for the Essence Stone?

She probably had no interest in participating in that league either, perhaps because the final reward was Essence Stone?

Essence stones, essence stones, why does Lan Ziye need so many essence stones?

Chu Xixuan asked, "You really like Essence Stone!"

"Of course, that's as important as my life!" It's the key to whether she can return, so how could it not be important?

"Then tell me honestly, what do you want the essence stone for? Just to set up a magic array? What kind of array do you want to set up? What is the purpose of setting up the array?" Chu Xixuan asked in a voice that became even colder.

It was only then that Lan Ziye realized something was wrong with Chu Xixuan. She looked up at him and asked, "What's wrong with you today? Did you take the wrong medicine?"

"Answer me, otherwise you will never get a piece of Essence Stone in the future. You know, to seal your Essence Stone, I only need one sentence!" Chu Xixuan said very seriously.

Threatening her with the Essence Stone again? Lan Ziye was completely speechless. (ー_ー)!!

She sighed and said, "The formation I'm going to set up is called the Demon-Slaying Formation. I invented it myself, and it's capable of slaying the Demon King. The most important element in that formation is the seven-colored Essence Stones. Not a single color can be missing, and we need plenty of each. So, if Young Master Chu has any information on Essence Stones, please let me know!"

Chu Xixuan felt his head buzzing. The words "demon-killing formation", "kill the demon king", and "self-invented" surrounded him like a curse, and he couldn't get rid of it. After a while, he took a breath and said, "I'll help you with your lessons tomorrow. I'm a little tired and I'm going to bed first!" After saying that, he didn't even look at Lan Ziye's reaction and walked out of the room.

Lan Ziye blinked twice. What on earth was wrong with this person? What did he mean? (⊙?⊙)

The next morning, Lan Ziye didn't see Chu Xixuan waiting for her at the table. She ate breakfast, but she had no appetite! Lan Ziye looked up at the housekeeper and asked, "Where's your eldest son? Did he go to exercise?"

Lan Ziye knew that Chu Xixuan had the habit of exercising in the morning.
