After making a plan, Li Yunmu turned to the deputy city master, "Which region is the richest in yin energy in the Ryukyu Small World?"
The deputy city master did not hesitate to answer him. "Reporting to lord, this lowly one doesn't know which region is the richest in yin energy. But to the south of our Yin Cloud City, there is a first grade city. I believe that everything the lord wants to know can be learned there."
Li Yunmu faintly glanced at the deputy city master. He knew why he was told to go to the first grade city. When he reached it, some expert there would deal with him.
But the deputy city master underestimated Li Yunmu's strength. Although he could not defeat Yin Emperor, there was no one in the Ryukyu Small World who could fight him.
"Hmph, you want me to go there and find my death?"
Li Yunmu coldly snorted. He hadn't thought that the people of the Ryukyu Small World would be such idiots. He then waved his hand and blasted the deputy city master out of existence without giving him any chance to say anything.
After that, Li Yunmu flew toward the first grade city just like the deputy city master had wanted. When he reached it, he saw that it wasn't a small city like Yin Cloud City.
The first grade city was extremely prosperous, with people going in and out of the city all the time. Li Yunmu wasn't very anxious to complete his objective, so he descended on the ground and slowly walked inside through the city gate.
He didn't go to the city master's residence this time, but entered a small tavern and found a corner to sit down. There, he began to listen to the conversations between the visitors of the tavern.
"Hey, did you hear, Yin Imperial Palace will open up after seven days!"
"What? It's being opened in advance this time!"
"That's only natural. I also heard that the city master invited the elites of all cities, and even Young Master Yin Xuan came out of seclusion."
"What a pity, only those people who can cultivate to heavenly tribulation stage or higher within a hundred years can enter the Yin Imperial Palace. Otherwise, people like us would get to try their luck too."
When Li Yunmu heard the conversation between two men, he became extremely curious. The system, which had been silent until then, chose that moment to speak.
[If my guess isn't wrong, Yin Imperial Palace should be the location of the goblet!]
"But why is the requirement of the emperor goblet that a person should reach heavenly tribulation stage or higher in less than a hundred years?"
System smiled, then said disdainfully. [Ha ha, it is possible that this is the requirement to awaken the emperor goblet and find a descendant.]
Among the immortals, the Heavenly Emperor Ryukyu was an ancient sage who had proclaimed himself a hegemon. But in the end, his name only existed in the passing down of his knowledge and cultivation methods to the younger generation.
Only his fame remained, but even it had diminished with time. Any small thing could result in his lineage vanishing completely.
[This emperor goblet is extremely useful for you. You may be able to use it to break through to the great principal golden immortal realm or even become a quasi sage.]
Li Yunmu's eyes began to shine after hearing the system's words. He hadn't expected that the emperor goblet would have such formidable energy. It seemed like he had to make a trip for it.
But he didn't know how he could enter Yin Imperial Palace, so he stood up and walked to the two men who had been talking earlier.
He looked at the two of them and asked with a faint smile, "Hearing the two of you talk, this lowly me became extremely curious. I wonder, how does one enter the Yin Imperial Palace?"
"Who are you? If you ask me to speak, then I will speak—"
Before the person could finish speaking, Li Yunmu slightly unleashed his presence, so only the two men could sense it. The speaker immediately shut his mouth in astonishment.
Li Yunmu was still smiling, but there was an extremely threatening look in his eyes. After the two men felt his presence, they became afraid that he would erase them both with a wave of his hand, and one of them hurriedly spoke up.
"My lord, just a moment ago this lowly one failed to recognize you. Sire must register at the city master's residence to enter the Yin Imperial Palace. Only those who have cultivated to heavenly tribulation stage or higher in less than a hundred years are allowed to enter."
Li Yunmu nodded, then left. The two men heaved a sigh of relief, but their clothes were already filled with cold sweat. They knew that they had narrowly escaped death, and after glancing at each other, they had a tacit understanding that they would keep the matter in their hearts and not mention it to anyone.
Li Yunmu quickly went to the city master's residence. While on his way, he questioned the people of Yin Cloud City whom he had captured in his heavenly world. From them, he understood that the heavenly tribulation realm in the Ryukyu Small World was roughly equivalent to the tribulation passing stage in the night pearl small world.
Li Yunmu then decided to suppress his cultivation to the initial stage of true immortal realm. That way, he could be counted among the upper middle tier in terms of strength among the people entering the Yin Imperial Palace.
What astonished Li Yunmu was that the city master's residence didn't have a strict control over who participated. After only testing his age and realm, they gave him a command tile and informed him to come in front of Yin Imperial Palace after seven days. After that, they didn't pay him any more attention.
Li Yunmu felt that Yin Imperial Palace wasn't as simple as he had imagined, so he decided to scout it out before doing anything rash.
At night, he figured out the position of Yin Imperial Palace and went to visit it. When he got close to it, he was extremely astonished.
The Yin Imperial Palace in front of him was an old tomb which resembled an imperial palace that had been built many years ago.
The moment Li Yunmu got close to it, he could sense the pressure it emitted. Yin Imperial Palace, the three words written on a board were hanging high above the large stone gate and added a hint of grandiose to the old tomb.
Just from looking at the old tomb, Li Yunmu could understand what kind of person Heavenly Emperor Ryukyu was when he was alive. He had surprisingly established a grand tomb which resembled a palace for himself.
Just when Li Yunmu wondered whether he should enter the tomb in front of him, he felt a sense of deep crisis and quickly rushed backwards.
Under his gaze, more than ten strands of yin energy transformed into long dragons and hovered where he had been standing just a moment ago. If Li Yunmu hadn't escaped in time, the yin energy dragons would have entered his body.
The trouble to get them out could only be imagined easily.
Li Yunmu's expression turned solemn. He realized that he couldn't force his way inside and needed to wait for seven days to enter with the people of the city master's residence.
He then quietly returned to the first grade city and found a family inn to stay.
Seven days passed in a flash, and Li Yunmu arrived in front of the Yin Imperial Palace. At that moment, a lot of people had already gathered there, and the majority of them had young faces.
A middle-aged man was standing at the front and was pointing at something. If Li Yunmu did not guess wrong, then that person was the city master of the first grade city.
His eyes darted around the scene, and once he saw that the majority of people were present, he nodded to himself.
"Almost everyone has gathered, so prepare to set off!"
