Returning upstairs, Lin Yu first went to Lu Heng's room, but Lu Heng was not there.
If he wanted to contact Lu Heng quickly, he could only go through Pang Hu, who lived on the first floor. Pang Hu and Lu Heng could communicate telepathically, which was why Lu Heng always left the Director in the apocalypse when he went to another world.
However, Lin Yu didn't have anything urgent to find Lu Heng for at the moment. He also wanted to ask Lu Heng for some accessories with larger storage space.
Unable to find Lu Heng, Lin Yu returned to his own room opposite, as some documents still needed to be carefully considered.
Meanwhile, Lu Heng had indeed entered his space again. He found a map of the Shenyuan Continent from the Lord's Mansion in Jinyang City and was contemplating where to find demonic beasts to contract on the Shenyuan Continent.
His current level on the Shenyuan Continent was Dao Comprehension Level Eleven, which was already higher than many cultivators there.
The Shenyuan Continent respected strength. With his current abilities, he no longer needed to be timid. As long as he didn't provoke families with deep foundations, Lu Heng could be said to have no rivals on the Shenyuan Continent.
In the apocalypse, the Siberian tiger was about to give birth. Lu Heng was also worried that the cubs would occupy his quota for contracted creatures.
"Lu Bai, what places have you been to on the Shenyuan Continent?"
"I don't remember." Lu Bai's fox ears twitched, and he curled up, lying not far from Lu Heng.
"I remember you've always lived in the Cloud Mist Forest."
"Yes, my previous master lived in a deep mountain. There were continuous mountain ranges there, but it's been too long, and I can't recall clearly."
"How old are you? Uh, I mean, how many years have you lived?"
"I don't remember either. I only remember that when I first followed my previous master, he was still a young child. Later, my master failed in his cultivation and died of old age."
Lu Heng, "...... You mean cultivation? Why haven't I heard the people of the Shenyuan Continent mention it?"
The people of the Shenyuan Continent had never mentioned anything about cultivation. Even with Wuchenzi, everyone just said they were practicing some techniques, which people referred to as Dao Comprehension.
As for longevity, they only spoke of improving their physical condition through elixirs, similar to ancient emperors seeking immortality.
"Then I'm not very clear either. The previous master was alone, and we had a wooden house in the deep mountains."
"Do you remember where that mountain is? And why did you go to live in the Cloud Mist Forest?"
After examining the simple map of the Shenyuan Continent again, he marked several places where mountains were depicted.
Logically, Lu Bai, a small fox, without the ability to fly, should not have migrated for a long time.
"It's probably hard to find. Sometimes, when there are too many humans on the ground, I would dig holes and travel underground."
Lu Heng really couldn't help it. He rolled his eyes. Lu Bai was clueless about everything. Lu Heng suspected that either Lu Bai was deliberately not telling him, or he truly had no brain.
As for Xue Lang and Xiao Liu, they were both natives of the Cloud Mist Forest, and asking them would yield no information.
He marked a mountain forest closest to the Cloud Mist Forest, thinking he could take Lu Bai there to have a look. Perhaps upon arriving at the location and seeing familiar surroundings, Lu Bai might remember something.
However, from Lu Bai's words, Lu Heng could confirm that Lu Bai had definitely lived for a very long time. He had outlived a human who wanted to cultivate, so he must be at least a hundred years old.
Furthermore, given his lack of knowledge and the absence of any signs of lying in his telepathic communication, it was possible that he had indeed lived too long and forgotten many things.
Lu Heng had originally intended to inquire through Lu Bai about where to find demonic beasts of similar levels on the Shenyuan Continent, or if there were any special demonic beasts, so he could contract them.
He hadn't expected that this inquiry would lead to the topic of cultivation.
"You come with me to the hospital. I'll give you a physical examination."
There was a hospital in his space. Lu Heng planned to examine Lu Bai's body, which would include some blood tests and X-rays.
Lu Bai's body was too peculiar. Lu Heng was unsure if Lu Bai's physical data changed between his fox and human forms, especially his blood data.
He wasn't a veterinarian either, and he didn't know if he could accurately determine Lu Bai's age from his human form.
Taking Lu Bai directly to the hospital in the space city, he first took X-rays of Lu Bai in both his human and fox forms. Fortunately, in his human form, the bone structure was no different from that of a human.
"How did you manage this? After transforming, even your internal structure became identical to a human's?"
Lu Heng held up the X-ray of Lu Bai in his fox form and compared it repeatedly with the human X-ray. He truly couldn't understand. It seemed it wasn't an illusion; this must fall into the realm of metaphysics.
No wonder people always said that the end of science was metaphysics. Lu Heng couldn't figure out the reason behind these two negatives.
However, Lu Heng also discovered a problem. In the skull of both Lu Bai's human and fox forms, there was an extra bone – a circular solid object.
This location, according to the medical knowledge he had learned, should not have had anything there.
Suddenly, Lu Heng seemed to recall something.
He put down the X-ray films and quickly exited his space, returning directly to his room in the apocalypse.
Downstairs, in order to examine the Siberian tiger, a lot of equipment had been set up, including an X-ray machine.
"City Lord Lu, are you here to see the Siberian tiger? Its condition is currently good, but its due date is within these few days."
A veterinarian, seeing Lu Heng's arrival, happily reported the Siberian tiger's situation to him.
"Yes, but I have something for you to do now. You know how to operate the X-ray machine, right?"
"Yes, I graduated from a regular medical university, but I majored in veterinary medicine."
"That's good. First, use the machine to take an X-ray of me. Just focus on the head."
Soon, an X-ray negative was produced. Lu Heng took it and examined it carefully. His skull image also seemed to have an extra bone.
"You have wood-element abilities," Lu Heng said, looking at the veterinarian. Survivors in the apocalypse, except for some elderly and children, had almost all become ability users by consuming crystals.
"Yes, I am now a sixth-tier wood-element ability user."
"Then go inside and stand there. I'll take an X-ray of you too."
"Oh, okay." The veterinarian didn't understand but complied obediently.
As expected, the veterinarian's X-ray also showed an extra bone-like structure in their head.
