"With this, those old fogeys wouldn't be able to see your Profound Vein. However, you can't underestimate them, understand?" Hong Wuya gave a warning.

Yang Chen nodded heavily while grasping the pendant. "Understood, Senior."

At this moment, Hong Wuya saw Linlin hopping onto Yun Lintian's shoulder. Astonishment appeared on his face before he gave a meaningful gaze to Yun Lintian.

Yun Lintian saw this. He frowned slightly and started to think of a way to hide Linlin's bloodline. All of the Monarchs couldn't be underestimated in the slightest. If they discovered Linlin was a divine beast, they would definitely try their best to snatch her from him. 

Yun Lintian suddenly thought of Mumu. Perhaps Han Bingling's presence scared these greedy monarchs away. He wondered whether he could use his relationship with her. However, thinking of an unpleasant incident with her this morning, Yun Lintian quickly denied this idea. He didn't want to rely on her much.

Hong Wuya saw through Yun Lintian's thoughts, he said. "You don't have to worry much about it. In this academy, there are no more than three people who could identify its true identity."

Yun Lintian said nothing, as he wasn't at ease. He would think of a way later.

"Hall Master Hong, I'm here to tell you something." At this moment, a loud male voice rang out from the outside of the courtyard. Judging from the sound, this person shouldn't be old. Yun Lintian was curious who was this person to use such an arrogant tone against Hong Wuya.

Hearing this, Bai Yun and Cai Xuwen's expressions turned cold. They seemed to know the voice's owner very well.

"Leave it to me." Bai Yun said and walked out of the courtyard.

Walking out of the courtyard, Bai Yun immediately spotted a familiar figure. Standing there was a tall, muscular young man. He had fierce-looking with sharp eyes and large muscles on his body. Just looking at him would make one feel the frightening power hidden within the muscles.

The muscular man was surprised upon seeing Bai Yun. "Bai Yun? How come you are here?" His face soon relaxed as he chuckled. "I see. You are here to see that old man for the last time, right?"

"Su Hang. This Bai hasn't seen you for a while. How come a small dog back then turns into a big arrogant dog now?" Bai Yun chuckled coldly. The muscular man in front of him was Su Hang, a lackey of Bai Yun's rival, Xie Tao of Starlight Hall. 

The muscular man, Su Hang, wasn't angry at Bai Yun's remarks. On the contrary, he laughed in a good mood. "Haha. Say whatever you like." He then cast a long glance at the courtyard behind Bai Yun as he said. "Where is the old man? Why didn't he come out to see me?"

Instantaneously, Bai Yun's aura burst forth, completely suppressed Su Hang. With a cold face, he said. "Your master hasn't taught you manner, didn't he?"

Su Hang's entire body trembled violently, trying to resist Bai Yun, but it was futile. Although his strength was already at the ninth level of the Saint Profound Realm, there was a massive gap between him and Bai Yun, who stayed at the peak of the Saint Profound Realm for a decade.

Gritting his teeth, Su Hang yelled angrily. "Bai Yun, do you think you are still a student here? Believe it or not, my master will kill you if you harm me!"

"Do you think this Bai fears him?" Bai Yun exerted more strength and directly made Su Hang kneel on the ground.

"That's enough." Hong Wuya's voice resounded from the courtyard, and the pressure around Su Hang instantly vanished.

Bai Yun's brows involuntarily creased together as he didn't understand Hong Wuya's action. With Hong Wuya's bad temper, it was already a miracle that Su Hang was still alive till now. Why did he suddenly prevent Bai Yun from teaching Su Hang a lesson?

Su Hang panted heavily for a while. His eyes were full of hatred, staring at Bai Yun. A moment later, he took a deep breath and stood up.

"What's the matter?" Hong Wuya's voice rang out once again.

Su Hang took out a small golden card and threw it at Bai Yun.

When Bai Yun caught the golden card, his expression changed drastically.

Seeing this scene, Su Hang laughed coldly. "Tell your Master to be on time." Afterward, he quickly left and disappeared from Bai Yun's line of sight.

Bai Yun stared at the golden card in his hand with an unsightly expression. To advance in the hall ranking, there were two ways to choose. First, surpassing other halls in terms of the overall trial ground ranking score. It could be achieved by the hall student. 

Secondly, each hall master could directly challenge the other higher-ranked hall masters. As long as they won the battle, their halls would replace the target's hall ranking directly. This golden card was a challenge letter to Hong Wuya, and he could not reject it no matter what, as it was written in the rules.

"Give it to me." Hong Wuya said calmly.

Bai Yun slowly returned to the courtyard and handed the golden card to Hong Wuya.

Cai Xuwen was mad when she saw this. "This Starlight Hall is too bullying!"

Hong Wuya took a glance at the appointed date and stored the card away. He looked at Cai Xuwen and asked angrily. "Why are you angry, lass? You have no faith in your Master?"

Cai Xuwen hurriedly shook her head. "It's not like that, Master. That Xie Yuan is too hateful. He didn't dare to say a word when Master was fine, but he actually did this after knowing you were suffered injuries."

Hong Wuya chuckled slightly, watching his beloved disciple puffing in a fury. "Remember, lass. This is the way of this world. Profound strength always comes first. When you no longer have it, you could only wait to be ripped by those hyenas."

Yun Lintian listened to Hong Wuya on the side and pretty much agreed with his statement. Whether it was Earth or Azure World, strength always came first. At the same time, he seemed to understand the meaning of the golden card. He didn't expect there was such a rule here. This academy was certainly interesting.
