Chapter 603: The key, Princess Yongning

Li Yun stood on the street blankly, frowning and looking around.
The beggar on the street was about 60 years old, his right leg was gone, his clothes were ragged, his face was wrinkled, and his face was yellow and skinny. Li Yun suspected that he was only in his thirties, and it was only because of long-term hunger that he was seriously aging.
The beggar kept begging with begging eyes, holding a dirty bowl, and begging for alms to everyone passing by.
But the weird thing was that Li Yun had already come to him, and the beggar still didn't look at him as if he hadn't noticed him, and didn't give him a look!
No, it's not just this beggar.
All the people on the street turned a blind eye to Li Yun, and had no reaction to Li Yun's weird dress except for not hitting him!
"I'm 2B!"
Li Yun smiled bitterly and patted his head. He was so stupid that he didn't notice these details.
It is strange that a modern man with short hair and weird dress appeared on the streets of ancient cities without causing commotion.
Helplessly, Li Yun was shocked by this illusion. He didn't expect that this time, he was still very interested, shopping like a fool!
Thinking of this, Li Yun came to a little brother selling candied haws and took a candied haws directly. This little brother didn't care, and continued to shout for candied haws.
"Sure enough, the people here didn't react at all to me, an outsider, completely treating me as air!"
Putting the candied haws back, Li Yun thought about the principle of this illusion, but suddenly thought of something.
"Princess Yongning!"
He immediately turned his head and chased in the direction where the sedan chair had just left, and directly chased after the princess's mansion. He was about to go directly in to find her, but was stopped by the guard at the door.
"Bold!!" Two soldiers with spears stopped Li Yun, and one of them shouted sharply: "Who is Erna, dare to trespass into Princess Yongning's Mansion? Don't leave quickly, or you will be killed on the spot! "
Li Yun was taken aback, the two slammed their spears, slapped them with the spear handles, and shouted at the same time: "Leave quickly, you cannot enter the princess mansion!"
"Uh, sorry sorry."
When Li Yun stepped back, the two soldiers were obviously abnormal. At least they were both innate and late. Li Yun estimated that even if he had been able to fight, he would have to explain it here once they called someone.
It's just that Li Yun is depressed, what kind of dynasty is this, it is too extravagant to use the master of the innate late stage as the door guard!
But at the same time, he also confirmed one thing.
Princess Yongning and Princess Mansion must be the most critical place for this illusion.
Because only she showed a shy expression after seeing Li Yun, and only people in the princess mansion would react to Li Yun's existence.
Li Yun thought about it, this large-scale illusion is like a sophisticated computer, but no matter how sophisticated the computer is, the running memory is also limited.
It is impossible to make it very realistic. If you control hundreds of thousands of people in the city at the same time to become lifelike, it will not accidentally occupy a large amount of resources, resulting in insufficient memory and crashes.
Therefore, most people in this city are puppets, only the Princess Mansion, and some important people are NPCs, that is, people with IQ.
After understanding, Li Yun looked at this gorgeous princess mansion again, and couldn't help showing a satisfied smile.
"Next, as long as I find out what secrets are hidden in the princess mansion, I may be able to escape from illusion!"
After deciding what to do, Li Yun began to walk around the princess mansion.
