The difference is that there are some purple bamboos planted around that Lu Qingan has never seen before. These purple bamboos exude a strong breath of vitality.

"This seems to be a longevity bamboo that has some longevity-enhancing effect on ordinary practitioners." Lu Qing'an found the description of this bamboo in his mind.

I had seen the description of these bamboos when I was reading the Book of Immortal Medicine.

It seems that although these people here are all mortals, they should have lived for quite a long time.

The old woman, supported by a pretty little girl of seven or eight years old, entered the house and began rummaging through a pile of books.

The cute little girl, under the old woman's instructions, clumsily made tea for Lu Qing'an and the other person.

After making tea, the old woman was still looking for something, muttering to herself, "Where did I put it? I'm too old to remember..."

Lu Qingan: “…”

Tu Zhengxing: “…”

The pink little girl did not go to help, but sat quietly opposite Lu Qingan and the others. She was not worried or afraid like the people outside the yard. On the contrary, her big eyes were full of curiosity. She sat opposite Lu Qingan and the others, supporting her chin with one hand, tilting her head to look at Lu Qingan and the others carefully.

Tu Zhengxing was also looking at the little girl. He didn't know why, but he always felt that he seemed to have seen this little girl somewhere, but no matter how hard he tried to recall, he just couldn't remember.

Seeing that the old woman was still searching, Lu Qing'an wanted to go up and help.

There must be something he wants to show them, maybe even Xu Zhenhuang's suicide note.

But before he stood up, the old woman muttered again:

"Could it be that it was accidentally burned last time..."

Lu Qing'an and Tu Zhengxing fell silent again.

It was also at this moment that they understood more clearly what the difference between immortals and mortals meant.

Lu Qing'an couldn't help but think of the past. If he hadn't traveled through time, perhaps he would have grown old one day and forgotten many things, even the people and things that were most important to him.
