They went upwards along the original path of the tomb.
After a series of actions and a fight by everyone, it was nearing afternoon.
"Wow, what a big moon."
Fatty covered his eyes with his hand, looking at the sun in the sky.
"Fatty, are you still half asleep? That's the sun."
Hu Bayi said, and then everyone walked out of the small sand dune.
Outside the sand dune, to Zhang Tian's surprise, An Liman hadn't run away. Instead, he was staring fixedly at Zhang Tian and the others.
"Yo, old sir, you're still alive and kicking."
Fatty walked over with a grin upon seeing this.
"Fatty, what kind of nonsense are you spouting? The old sir is in good health, how could he have passed away prematurely?"
Hu Bayi rolled his eyes at Fatty.
An Liman stood up.
"Well, I said that heaven would protect you all."
"Moreover, I'm only in my thirties this year, friends, I'm still young."
An Liman said, and then stood up from the felt mat, walking towards Zhang Tian and the others.
"Did you find anything inside?"
An Liman looked at Zhang Tian curiously. He often took tourists to the desert, but he had never explored a tomb, let alone seen anything inside.
"A portrait of a Loulan princess, nothing else."
Zhang Tian waved his hand and casually took out the portrait for An Liman to see.
Perhaps An Liman would know the location of the ancient city of Loulan after seeing the portrait.
Indeed, when An Liman's gaze fell upon the portrait, his eyes lit up.
"Well, a celestial maiden descending to earth. No wonder my grandfather was so infatuated. There's a reason for it."
An Liman said, and a hint of appreciation for beautiful things appeared on his face.
An Liman looked for a long time before shifting his gaze from the portrait.
"How is it, old sir? You've seen this portrait, have you remembered anything?"
Hu Bayi asked An Liman, looking at him.
Everyone else also turned their attention to An Liman.
"Well, I do recall one thing."
An Liman said, scratching his head.
"My grandfather told me that deep in the Black Desert, at the end of a river, there was a large kingdom. In that kingdom, weapons and arms manufacturing were abundant."
"And that river was also called the Sand Weapon River."
An Liman said, and then scanned his surroundings again.
"But this Black Desert is so vast, and filled with yellow sand, how could there be a river?"
He said, and Zhang Qilin spoke from behind.
"The underground river we saw inside should be it."
After he finished speaking, Zhang Tian's eyes lit up.
If that was the case, then there was no doubt.
There was an underground river in front of the tomb of the Prince of Gu Mo. If An Liman was telling the truth,
then by following that underground river all the way up, they might be able to find the location of the Loulan kingdom.
Of course, to calculate the exact location of the river, Hu Bayi's task would be quite challenging.
After all, finding the flow and exact location of an underground river in the thick desert was definitely not an easy task.
"Old Hu, can you find the exact flow path of this underground river?"
Zhang Tian looked at Hu Bayi.
Hu Bayi took out Shirley Yang's map.
"The desert is too vast, and there are no accurate route maps in the desert, so it's a bit difficult."
"However, I will try my best to deduce it. We can set up camp here tonight and stay for one night."
Hu Bayi said, planning to determine the accurate location above the river based on the river's course from the tomb of the Prince of Gu Mo.
Zhang Tian nodded in agreement, and then everyone walked back towards the ancient well.
They planned to sleep by the ancient well that night.
This place not only offered shelter from the occasional sandstorms but also protected them from the scorching sun.
In the desert, the sun was the most dangerous. If a person was exposed to the sun for more than three hours, their body's water would be irreversibly lost.
Upon returning to the ancient well, Fatty went to find some firewood, while Zhang Tian and the others spread out some mats on the ground.
This way, everyone could get a good night's rest.
After finishing, Zhang Tian sat down in a meditative pose, beginning to recover the true qi consumed within his body.
Zhang Qilin sat silently by the side without speaking.
"According to the map, I estimate our location to be here. And based on the surrounding mountains, there should be a low-lying basin above."
"From a geographical perspective, this could very well be the source of the water flow."
Shirley Yang looked at the map before her, using her sharp mind to guide their path.
Hu Bayi looked at the route indicated by Shirley Yang. He had to admit that Shirley Yang was indeed intelligent.
Even with such a large map, she could pinpoint locations.
"This location is indeed possible, but from a feng shui perspective, this is a dangerous place."
"Look, the Vermillion Bird Gate star in the south directly illuminates the entire depression, forming a dead end. Given the prosperity of the Loulan kingdom at that time, it's impossible for them to have built their city there."
Hu Bayi said. Shirley Yang was a little confused about what Hu Bayi was talking about.
She had never even heard of things like the Vermillion Bird Gate star in the south.
However, she didn't get angry at Hu Bayi's denial, as Hu Bayi's abilities were indeed very strong.
"So, where should we go?"
Shirley Yang looked at Hu Bayi.
Hu Bayi slowly walked out of the sand dune, holding a small wooden stick in his hand.
The compass was constantly spinning.
"From the direction of the underground river, we are currently in the central area of the Western Constellation, the White Tiger Constellation."
"To find the upstream of the underground river, we must travel from this west to the east."
He said, and Hu Bayi drew a diagram on the ground.
"You mean, we can just follow the positions of the constellations?"
Shirley Yang asked.
Hu Bayi nodded and then shook his head.
"The flow of rivers and mountains is the law of nature. How can it be deduced by constellations? Unless this river was artificially constructed."
"Let's wait until tonight. I'll take another look tonight, and I should be able to find the flow direction."
Hu Bayi said, and Shirley Yang nodded.
"No need to rush too much. There's still plenty of time."
Shirley Yang said, and Hu Bayi nodded, his mind still preoccupied with the river.
At this moment, Fatty, carrying a large pile of firewood, came running back in a hurry from not far away.
"Boss, it's strange. Judging by the architecture and simple routes in this city, Fatty discovered that there should have been a river here before, but now it's dried up."
Fatty threw the firewood on the ground and couldn't help but exclaim.
"You can actually spot rivers?"
Zhang Tian was a little surprised, and Fatty chuckled.
"Boss, Fatty is proficient in all eighteen skills."
"A man cannot say he can't do it!"
Fatty said very seriously.
Zhang Tian patted his forehead, ignored Fatty, and continued to cultivate.
Hu Bayi, upon hearing Fatty's words, immediately got up.
A hint of excitement appeared on his face.
