Ann Sudong still could not believe that such a great figure as the Old Master Hong would want to recognize him as his foster grandson.

"Hey, why aren't you answering? Do you know how many people there are who want to call me grandpa?" If you also become my grandpa's grandson, then you really are my big brother. Aren't you happy to have a little sister like me? "

Seeing the Ann Sudong who did not display any expression, Hong Yingyue could not help but step forward and pull the corner of Ann Sudong's clothes.

"My dear granddaughter, this is the decision of the Ann, even if he doesn't want to, we can't force him."

Seeing that Ann Sudong still did not express anything, Old Master Hong neither refused nor agreed, and did not continue to talk about this matter.

"Let's talk about this later, Ann. Let's go, don't always stand here and chat."

Patting Ann Sudong's shoulder, Old Master Hong laughed.

Being able to be selected by the Old Master Hong was indeed a matter of great fortune, but on one hand, it was unintentionally that he had saved the Old Master Hong, and he had also received Hong Zixiao's gratitude of a million years ago. On the other hand, if he became a grandson of the Hong Family for the first time today, it would make people feel that he had taken a fancy to the powers and money of Hong Family.

"Don't even think about it. Just let nature take its course and there will be an answer."

With Old Master Hong's eyesight, it was naturally not difficult for him to tell what Ann Sudong was worried about. However, the fact that Ann Sudong did not immediately agree to it made him admire and approve of Ann Sudong even more.

Old Master Hong made a gesture of invitation and smiled at Ann Sudong.

As soon as he sat down, the Old Master Hong asked: "I always had a question."

When Ann Sudong heard this, he already knew how Old Master Hong would treat his brain cancer.

"Please speak."

The Old Master Hong leaned forward slightly, his eyes staring at Ann Sudong with a burning gaze. He wasn't as amiable as before and instead spoke in a serious tone, "You are so young and you are still a student of the Medical University. Where did you learn such good medical skills?"

Pausing for a moment, Old Master Hong reminisced with a bit of lament before continuing, "It can even cure my brain cancer."

"Eh."

Ann Sudong naturally could not tell Old Master Hong that he had connections with the five medical geniuses and the deities in China. That way, Old Master Hong and Yingyue would think that he was deliberately making up a story.

But the truth was like this. If not for the immortals' help, Ann Sudong definitely would not have been able to cure Old Master Hong's brain cancer.

"Is it inconvenient for you to reveal?"

Old Master Hong saw the worry in Ann Sudong's eyes and thought that Ann Sudong's master was some kind of medical expert and wasn't willing for Ann Sudong to say it out loud.

"Eh."

Ann Sudong hesitated for a moment, and decided to follow Senior Hong's thoughts, if not, the matter of the deities would be too shocking.

"I'm sorry, Senior Hong, I really can't say it out loud."

After he finished speaking, Ann Sudong tried his best to make a firm expression as he looked towards Old Master Hong and Hong Yingyue.

Ann Sudong's real master could be considered a demon in Chinese medicine. Although he had always been respected and respected by people, he had long passed away, so this was something that could not be said.

Old Master Hong was stunned, he continued to stare at Ann Sudong.

Hong Yingyue, who was at the side, also seemed to be deep in thought, and from time to time, she would look at Ann Sudong with a gaze of disbelief, as if she could see through Ann Sudong completely.

"I'm sorry, I promised Master that I wouldn't say a single word about him. Please don't be angry."

Ann Sudong took a light breath and said with a voice that was as calm as possible.

Ann Sudong was very nervous about making up such a lie in front of Old Master Hong, he only tried his best to appear calm on the surface.

"So that's how it is. Help me thank your master."

In the end, Old Master Hong gave Ann Sudong a meaningful glance, and couldn't help but feel slightly regretful.

Old Master Hong had long predicted that if Ann Sudong had an extremely powerful master, he would definitely not let Ann Sudong divulge even the slightest bit of information. Even so, the Old Master Hong could not help but ask. After obtaining an affirmative answer, he felt a little disappointed.

"Grandfather."

A trace of exhaustion flashed past Old Master Hong's somewhat disappointed eyes. He didn't know why, but at this moment, Ann Sudong and Hong Yingyue could see some of the vicissitudes of life in Old Master Hong's body. It was as if they could feel a pioneer walking on a desolate mountain ridge.

"Senior Hong, don't think too much into it. My master has long since stopped asking about the human world, so he doesn't want the world to know about it."

Thinking about his Masters from the Underworld, Ann Sudong sighed softly. He really couldn't bear to let Old Master Hong experience even more exhaustion and vicissitudes.

Old Master Hong smiled as he patted Hong Yingyue's small hands, then gave a hearty laugh towards Ann Sudong. His face no longer had any signs of the vicissitudes and tiredness from before.

"How old is your master?"

Pausing for a moment, Old Master Hong still could not help but ask Ann Sudong's master.

He thought that he had overturned the topic of Master, but he never thought that Old Master Hong would actually be so persistent. Ann Sudong seriously thought about it. If he had to calculate it from the time that his Masters were alive, then that master would be hundreds to thousands of years old. If he added them all together, he would be thousands of years old.

"What …"

The moment Ann Sudong opened his mouth and said one word, he realized that he said something wrong, so he immediately changed his words: "I don't remember."

"I can't remember?"

This time, even Hong Yingyue could tell that Ann Sudong was deliberately lying.

Scratching his head, Ann Sudong said helplessly: "Actually I have five masters, they have long passed away. And I really can't remember the age of every single one of my masters. "

Five masters?

Old Master Hong looked at Ann Sudong with great shock.

Since Ann Sudong was young, then his master must be even more skilled than him in his medical skills. It was hard to imagine that the young Ann Sudong actually had five Divine Doctor level masters.

Could it be, that Ann's five masters have never revealed themselves?

After carefully recalling all that had to do with medical skills, even the Old Master Hong did not have any judgement towards the five masters that Ann Sudong had mentioned.

Looking at the grandfather-grandson pair that were trying very hard to remember, Ann Sudong felt a little guilty. Who would have thought that the five masters he had mentioned were the ancestors of Chinese medicine like Bian Que and Li Shizhen?

After searching through his memories but to no avail, Old Master Hong could only sigh regretfully, wishing that he had the chance to meet these hidden masters in the medical arts.

"Senior Hong, you don't have to be so regretful. I will pass on your gratitude to my Masters. They will definitely sense it."

Ann Sudong could not bear to let the Old Master Hong feel sad. He thought that once he returned from the Hong Family, he would definitely buy some delicious foods and teleport over to his masters, so as to explain to them the sincere gratitude the Senior Hong had for him. Thus, he made a promise that he would definitely pass on the gratitude the Senior Hong had shown.

Old Master Hong nodded gratefully towards Ann Sudong, thinking that Ann Sudong was comforting him, he laughed bitterly and stopped thinking about it.
