The witch chose to conceal her plan and did not tell Xu Xi about it.

She knows.

This matter is too difficult.

If anyone knew the difficulties, they would dissuade her from wasting time.

Therefore, Kris Wu clumsily and cautiously carried out various attempts to prolong her life on the premise of "hiding" her system.

"Teacher, please be careful!"

Traveling around the world.

Compared to the past, the time Kesha's gaze stayed on Xu Xi became noticeably longer.

Full of worries.

Full of tension.

I found a slightly raised stumbling block.

Kesha will be cleared urgently.

"Kusha, I'm actually still in good health."

"Please rest assured, I understand."

The witch answered while looking around cautiously, and it seemed that he didn't understand at all.

————

East side of the magical world.

There is Dragon Island in the center of the huge lake.

Under the gentle education of the system, Krissa understood what the "secret of taming a dragon" was, and the knowledge reserve in her brain increased.

Leaving Dragon Island that night.

The night is dark.

Pitch black.

The witch came back here alone, and wherever her eyes swept across, the dragons all trembled and bowed their heads, not daring to make a sound.

"According to the records in the classics, bathing in dragon blood can improve one's health."

"Strength, spirit, and longevity."

"After bathing in dragon blood, everyone can be improved to a certain extent."

The witch muttered to herself.

At the same time, he took out a note that he had prepared in advance and flipped through the marked information.

Nod your head slightly.

The night wind rustles the grass and trees on Dragon Island.

The witch, wrapped in the wind element, rushed into the dark area of ​​Dragon Island at an extremely fast speed.

About ten minutes later.

When Kesha left Dragon Island, there was a heavy pottery jar in her arms. Her solemn expression seemed as if she was guarding the most precious thing.

However, this solemnity came and went quickly.

The witch came to a disappointing conclusion.

The material in the tank does not have the effect of extending the life, at least not on many systems.

"Failed..."

"Whether I asked the instructor to apply it on his arm or mix it into food, it had no effect."

Kesha was very disappointed.

She poured the remaining material in the can onto the weeds on the roadside.

A batch of red dragon blood grass was accidentally produced.

These dragon blood grasses were in line with Xu Xi's aesthetic taste, so he put them into his space ring and prepared to take them back to Allenson City for planting.

————

A day, a month, a year.

Time flows quietly.

The immortal witch tried her best to prevent the death of mortals, but she could only watch helplessly as the glory became dim.

She tried every possible method she could find, but nothing worked.

"I'm sorry, mentor..."

"Why are you apologizing to me, Kesha? You didn't do anything wrong."

Xu Xi opened his sleepy eyes, his face looked old, with wrinkles clearly visible in the sunlight, his face was old and withered, but his smile was still gentle.

He smiled and affirmed all the witch's efforts.

Said he had seen it all.

"Do you know everything?"

"Rather than knowing, it's hard to pretend not to see it."

The man smiled again.

The smile blends into the bright sunshine.

Gentle as water.

He stretched out his skinny hand and stroked her long gray and silver hair for the last time, with reluctance in his eyes: "Kusha, I am the one who should apologize."

"I took it upon myself to be with you, and I took it upon myself to leave you alone."

"I'm so sorry..."

"Cough, cough, cough, cough..."

Bright red liquid leaked out from between the fingers covering the mouth, dripping silently.
