Heaven-defying Upgrade System

Xiao Ruyu quickly smiled and said, "Master Cai, my brother's fate is very miserable. He was born with severe depression and was stuck at home all day long. It was not easy for him to accompany me out today, so you can bring him to take a look."    

Cai Liuying looked at Liu Fei in surprise as if she was thinking of something. After a while, she said, "Alright, since he is a disabled person, then I will reluctantly accept it."    

Liu Fei fiercely glared at Xiao Ruyu. This little girl was simply speaking nonsense. Without his permission, she said that she had depression. But luckily, Cai Liuying seemed to believe it.    

Walking in the Heavenly Spirit Institute, the scenery here could no longer be described with the word beautiful. Everything in front of them was extremely shocking, especially the houses floating in the air. It was like the place where the elves lived. There were often people who flew out and flew out. The green surface was covered in a layer of faint white fog, which was hazy. It was like... It was a fairyland. It was just like that.    

Apart from that, the towering and towering buildings also displayed its unparalleled grandeur.    

"How is it? The style of our Heavenly Spirit Institute can be considered grand!" Cai Liuying smiled. Her eyes were filled with pride as she walked out of a few academies. Furthermore, her temperament was unique. When she saw Cai Liuying, she respectfully greeted, "Hello Master Cai!"    

Cai Liuying nodded her head seriously. It was as if the form teacher had seen a student. Liu Fei laughed secretly behind her. Cai Liuying turned around and gave him a fierce glare before leaving with big steps. Liu Fei immediately followed closely behind.    

Suddenly, a towering building appeared in front of him. It rushed straight into the clouds, as if there was no end to it. The entire building was shaped like a pagoda. However, the material was a type of black wood, which looked unusually hard.    

"Master Cai, what is that?" Xiao Ruyu asked curiously.    

Cai Liuying introduced, "That is the Evil Dragon Tower. It is said that the dean of Heavenly Spirit Institute fought with an evil dragon that invaded the White Wood Clan for several days. Although he didn't kill the evil dragon, he severely injured it. After the evil dragon escaped, the dean cut off a long black horn from its body. This Evil Dragon Tower was made from the dragon horn, using the energy within the dragon horn. The dean has refined an extremely powerful magic treasure that can be used to protect our Heavenly Spirit Institute. "    

"Evil dragon?"    

Liu Fei's eyes suddenly widened as he stared at the Evil Dragon Tower. A familiar feeling hit his face.    

Cai Liuying saw Liu Fei like this and couldn't help but smile, "What is it? Is it suppressed by our academy's power? Hmph, let me tell you, there are still many things that shock you." Following that, she saw that Liu Fei's expression seemed to be somewhat strange.    

Liu Fei stared at the Evil Dragon Tower and circulated the Yitian Record in his body. He said coldly, "How shocked are you? You have to show me. Maybe I will really consider staying here."    

After stepping into the academy, the Evil Dragon Tower seemed to have come alive. It actually let out a low roar, and with a loud bang... The entire Heavenly Spirit Institute instantly changed its color. It stared at the pagoda that was covered by gloomy clouds. Liu Fei raised the Heaven-defying Strength.    

An invisible energy instantly enveloped the Evil Dragon Tower.    

Hu!    

Like a gust of wind, the dark clouds that hung low in the sky actually disappeared, and the surroundings instantly calmed down.    

Whoosh! Whoosh! Whoosh!    

A few streaks of light streaked across the sky, and dozens of cultivators flew over. They looked around vigilantly, and a portion of them flew towards the Evil Dragon Tower. However, after checking, they didn't find anything unusual.    

One of the cultivators said, "Master Cai, was there anything unusual here? Why did the Evil Dragon Tower shake so violently?"    

Cai Liuying said in surprise, "Nothing unusual, I also feel strange. The Evil Dragon Tower seems to have come alive..."    

Those people looked around blankly. Normally, if there was no terrifying threat, the Evil Dragon Tower would not have such a situation. Could it be that something unusual had happened to the Evil Dragon Tower?    

Thinking about it, they went over to check again. Cai Liuying did not take this matter seriously. She only glanced at Liu Fei and led them towards the depths of Heavenly Spirit Institute.    

Heavenly Spirit Institute was very large. Every student's location was different. The teacher who guided the students also did not have a fixed place. If they wanted to explore the entire Heavenly Spirit Institute, one day wasn't enough.    

When they came to a quiet courtyard, Cai Liuying pointed there and said, "Xiao Ruyu, that is where you live." Because that place was the head chef of the female students, Liu Fei was not convenient to go in. So Cai Liuying accompanied her in, while Liu Fei himself continued to walk around the academy.    

Arriving at the square in the north, he stared at the Evil Dragon Tower and circulated the Heaven-defying Strength. Liu Fei felt a gloomy aura, as if there was a huge dragon roaring inside. The Evil Dragon Tower was a little strange, as if it had something to do with the Five-clawed Golden Dragon.    

Liu Fei thought to himself.    

Whether he could leave this mystic realm or not, perhaps he could start with the Evil Dragon Tower. Furthermore, this was the Heavenly Spirit Institute, a place for cultivation. There would definitely be a lot of things he could obtain by staying here. ...    

Now that the situation in Heavenly Whistle Gang had settled down, even Si Yin and Bai Muyun had things to do. For the time being, there was no need to worry about the situation outside. It shouldn't be a problem for him to stay in the Heavenly Spirit Institute.    

After circulating the Heaven-defying Strength and staring at the Evil Dragon Tower for a while, Liu Fei retracted his gaze. If he kept looking at it, perhaps something unusual would happen. It wouldn't be good if someone found out.    

A white light streaked across and Cai Liuying appeared in front of Liu Fei. She looked at him curiously. She had a feeling that this man in front of her wasn't simple and was a little mysterious.    

Cai Liuying said to him, "Alright. If you have nothing else to do, you can leave this place. Heavenly Spirit Institute still has restrictions on outsiders."    

Her meaning had already been made clear. She would not let Liu Fei stay here for long.    

Liu Fei looked at Cai Liuyun. It seemed like she wasn't very good at handling internal affairs. He estimated that she would come out after throwing Xiao Ruyu to her residence.    

Now that Liu Fei had developed a strong interest in this place, of course he would not go out. He looked at Cai Liuying and suddenly asked, "You just said that if I want to enter Heavenly Spirit Institute, I still have a chance, right?"    

Cai Liuying was slightly stunned. She did not expect Liu Fei to take it seriously.    

At his age, it seemed that it was already too late to enter the Heavenly Spirit Institute again. However, Cai Liuying could see that Liu Fei seemed to want to stay here. She then said to him, "That's right. There is indeed a chance to stay here, but the examination here is still very strict. If you want to learn and cultivate, I can give you some guidance. "    

" The examination is strict, could it be that the opponent is very strong? " Liu Fei did not mention anything about Cai Liuying instructing him, but about the Dao Seeking test.    

Cai Liuying was very unhappy in her heart. Liu Fei's attitude was not good. In Heavenly Spirit Institute, there were not many people who dared to treat her like this. Taking a deep breath, Cai Liuying suppressed the anger in her heart. She said, "If you want to be like Xiao Ruyu and become a low-level student, your opponent is only a cultivator below the Spirit Pill level, but looking at your age... Your opponent is at least a Seventh Sky Spiritual Core Stage cultivator, so you want to pass the test. It was extremely difficult. Of course, if you want to challenge someone with a higher cultivation base, if you want to become an advanced student, your opponent will naturally be stronger. Furthermore, if you wanted to enter the ranks of the four elite students - Gold, Silver, Bronze, and Iron - It's possible, but I don't need to say much about the difficulty."
