At that moment, the elder looked at Yi Yun and asked, "You are probably here for the Yang spirit, right? Sigh, you are Yan'er's benefactor so if you seek it, I will not stop you."
"It's extremely dangerous here," he continued. "You can avoid the humanoid creatures outside by wearing the jade burial suit but when you reach the core depths, other dangers await you. I have been trapped here for a great deal of time but have failed to obtain the Yang spirit, nor have I been able to leave this place. I was acutely aware that the Divine Secrets Trading Company would be in extreme danger without me, but I was helpless to do anything about it. I can't provide much help other than to point out the path for you."
Yi Yun hurriedly said, "Senior, just this jade burial suit alone has helped me greatly."
If not for the jade burial suit, Yi Yun would probably not be able to take a single step further. Those humanoid creatures were too terrifying.
The elder used a dagger to carve a map on the ground.
The underground world had a complicated layout. Without a map, one would probably take get sidetracked during a simple random walk.
"This is the core region. Once you enter it, even I will not be able to help you." The elder tapped a particular spot with his dagger.
Yi Yun memorized the map and, perplexed, asked, "Senior, could it be that you have not entered the core region as well?"
The elder waved his hand, wiping away the map on the ground. He looked up and a deeply repressed pain seemed to flash in his recessed eyes.
"Young Master Yi, I still have something I would like to ask of you." The elder suddenly bowed.
"Senior, there's no need for that. Just speak your mind." Yi Yun hurriedly stopped him. Despite being close to death, the elder still insisted on bowing. It meant that the matter was extremely important to him.
The elder had saved Yi Yun's life so, if the request was possible, Yi Yun would fulfill it.
"If Young Master Yi were to encounter Shuiyan's father there, please check to see if he's alive or dead," said the elder.
In fact, the elder had been waiting outside for a very long period of time. He knew that the odds were greatly against Shuiyan's father.
"About that… Senior, you can enter the tower along with Xin'er and Yue Xiao," suggested Yi Yun.
The elder was wearing a jade burial suit so he faced no threat from the humanoid creatures. However, various factions, including the Seven Star Dao Palace, would be entering the Sun Burial Sandsea at any time.
"If that's the case, I'll be pinning my hopes on Young Master Yi. This mother part of the Heaven Secrets Compass will be able to confirm your position regardless of the environment. Young Master Yi, please take it." The elder hesitated for a moment and did not give any excuses. He too wanted to find Shuiyan's father, dead or alive.
After Xin'er and Yue Xiao carefully helped the elder up and into tower, Yi Yun withdrew the God Advent Tower. Holding the mother-child pair of the Heaven Secrets Compass, he walked out of the cave.
Following the map, Yi Yun once again returned to the side of the molten metal river.
The nine heads were bobbing on the surface of the lake. Their empty eyes scanned their surroundings and looked horrifying. However, it was as though they could not even see a living human like Yi Yun, who stood right in front of them.
Yi Yun glanced at them before walking upstream beside the river. There were powerful pure Yang laws contained within the molten river, and its source was located precisely in the core region of the underground world.
As Yi Yun ventured deeper, he saw other ancient creatures. They were different than the humanoid monsters, but still terrifying. Although they were very few in numbers, one or two of those existences were enough to result in certain death.
This treacherous land did not permit the existence of ordinary people. Furthermore, the river split into many distributaries. They bored through countless tunnels and forks in the underground world, so one could easily get lost before they even knew it.
When he came to a fork, Yi Yun saw a dark red lake that had pooled a large amount of molten liquid. It was the lake that he had encountered when he first entered the underground world.
Why am I back at the entrance?
Yi Yun faltered for a moment before quickly realizing that he had not truly returned to his original spot but that the spatial laws in the underground world were extremely chaotic. Although he could see the path that he had previously trodden, he was in fact separated by multiple layers of space.
If he were to truly approach it, he would realize that the distance did not change. However, returning to that path would be an exacting task without a map, even with his comprehension of spatial laws.
Yi Yun proceeded forward and, according to the elder's map and the Heaven Secrets Compass's guidance, constantly tweaked his direction, gradually approaching the core of the underground world…
Suddenly, Yi Yun heard a loud rumble as several figures subsequently descended.
Upon seeing these figures, Yi Yun's pupils constricted.
They were people from the Seven Star Dao Palace!
Yi Yun wanted to retreat immediately, but he realized that the surrounding spatial laws were so chaotic that the Seven Star Dao Palace group that appeared to be in front of him was actually located a great distance away.
Upon realizing this, Yi Yun immediately calmed. He stroked his chin and pricked his eyebrows up. He came to a halt unhurriedly.
"Haha, we have finally found the entrance." A young looking man from the Heaven Secrets Chapter said with a hearty laugh, as though he was trying to gain credit.
They had been wandering aimlessly in the Sun Burial Sandsea for a while and had finally entered the underground world. Upon entering, they could immediately sense the searing hot gases which indicated that they had found the correct location.
"Thankfully, my geomancy techniques were of some use." A middle-aged scholar looked rather smug as he held a compass.
Yi Yun recognized the middle-aged scholar immediately. He was Master Tianxiao of the Heaven Secrets Chapter. Back at the trade session, he was the one that revealed the Divine Secrets Trading Company's possession of the Heaven Secrets Compass.
And among the crowd, Yi Yun also noticed a woman dressed in a palatial gown, Liu Ruyi. Standing beside her were three people with tremendously powerful auras. Yi Yun took note of them.
A black-dressed middle-aged man slung a large saber behind his back. On the other side of Liu Ruyi were two identical-looking children dressed in red bodices.
Although they looked like children, their eyes were extremely cold and mature. Their gazes were extremely icy and looked like human paper cutouts that mortals burned to honor their ancestors.
The Seven Star Dao Palace had placed a great deal of importance on the Sun Burial Sandsea's phenomenon. While the Palatial Lord held down the fort in the Seven Star Dao Palace, he sent the four deputy palatial lords, including Liu Ruyi, to Sun Burial Sandsea.
"Unfortunately, the precise location of the Yang spirit is difficult to divine. In this underground world, geomancy techniques are greatly affected. With the Heaven Secrets Compass, it would be possible to find the proper direction. It's a pity that the Heaven Secrets Compass is in Yi Yun's hands." Master Tianxiao said with a sigh as he shook his head.
"Yi Yun? Is he the punk that's hiding in the Clarity Pool Sword Sect?" One of the twin children suddenly asked. His voice sounded old but it was sharp and shrill. It gave anyone who heard it the feeling that their eardrums were being scratched ruthlessly.
"Hehe, it doesn't matter. For the all the trouble he's given us, we will wipe out the Clarity Pool Sword Sect in the future. As for the punk, since he possesses good talent, I will eviscerate him and use him to refine elixirs," said the child sinisterly.
"Yes, yes." Master Tianxiao shuddered as well when he looked at the child.
