Soon, when Si Yun came in, he did not find Bibi Dong on the bed. It seemed that she was not practicing in the room.

The things in the room were arranged neatly as usual.

'Not here, is he practicing in a secret room?' Si Yun thought. He remembered that the inheritance of the Rakshasa God seemed to have a secret room.

After taking a quick look around the room, Si Yun didn't dare to do anything and just sat on the stool and waited silently.

The moment Si Yun came in, Bibi Dong, who was practicing in the secret room, discovered his arrival through the mechanism, but she had no intention of going out. She believed that with Si Yun's ability, he would be able to find that the entrance to the secret room was behind the bookcase.

She could only use her backup plan after Si Yun came in. As for Nihuang Douluo, he was imprisoned in the deepest level of the secret room, and one had to pass through her secret room to reach Nihuang Douluo, so she was not worried that Si Yun would find Nihuang Douluo.

Time passed by minute by minute, and the sun was about to set, but Bibi Dong had not returned yet. Si Yun vaguely felt that something was wrong. Bibi Dong was the Pope. Without advance arrangements, the Spirit Hall could not do without her for a day. She should come back every day. Could it be that she was still practicing in the secret room?

Thinking of this, he glanced at the wardrobe not far away. Having stayed here for such a long time, he had already discovered the secret door hidden behind the wardrobe with his detective eye. If he guessed correctly, this should be the entrance to the secret room. If he went in from here now, he would most likely find Bibi Dong.

It was not a solution to keep dragging it on like this, and Bibi Dong had not come back for such a long time, she might have encountered some danger. After hesitating for a while, he decided to enter the secret room to see if anything had happened to Bibi Dong.

When he came to the wardrobe, Si Yun seemed to have known that there was a mechanism here. He pulled out the second book from the left to the right on the bottom layer. In an instant, the wardrobe moved to the right by itself, and a straight iron door appeared in front of Si Yun.

Pushing open the iron door, he saw a strange tunnel without any light in front of him. Without any hesitation, he walked in. His reconnaissance eyes could see that there was no danger inside.

This tunnel goes underground and is quite long. Si Yun walked about 500 meters before finally arriving in front of a stone door. Thinking that Bibi Dong might be behind this stone door, Si Yun became a little nervous. After all, he was about to confront Bibi Dong and draw a clear line between them. How could he not be nervous?

After taking a deep breath, he pushed open the door. However, the moment he opened the door, he saw a familiar figure appear in front of him.

"teacher?"

For some reason, although it was clearly Bibi Dong's back, Si Yun felt that the scene in front of him was a little strange. The aura that Bibi Dong gave people today was very strange. It was a very weird and evil aura.

As if she heard Si Yun's voice, Bibi Dong's body trembled, and then she slowly turned around. When she saw Bibi Dong's eyes, Si Yun's pupils condensed, and then she immediately retreated.

Now Bibi Dong's eyes were filled with dark green light, exactly the same as when Tang San's supernatural power went out of control before.

"Could it be that Bibi Dong is also in a state of divine power rampage?"

After this idea appeared in Si Yun's mind, his expression immediately became serious. Bibi Dong's rampage was not on the same level as Tang San's. Before, Bibi Dong could beat him up using the Rakshasa power in her normal state, but now that the power was rampaging, he would die if he was not careful.

The next second, Si Yun's martial spirit possessed him, and in the blink of an eye, Bibi Dong appeared in front of him, reaching towards him with one claw.

In the blink of an eye, Si Yun also used several soul skills, Gale Mode, Demon God Domain, Killer God Domain, and Wind and Thunder Starter were all activated, and his physical condition instantly reached the peak. But even so, Bibi Dong's speed was still faster than his, and in the blink of an eye, she left three scratches on his chest.

The armor that Si Yun was proud of was directly torn apart. The next second, six tentacles appeared behind Si Yun, and the Iron Tentacles were activated. This was his most powerful skill so far. The power of the six tentacles combined, although not as exaggerated as the Dark Gold God-Teasing Claws in terms of lethality, was much stronger and the continuous consumption was much smaller.

The next second, Si Yun's tentacles and Bibi Dong's claws collided head-on, forcing Bibi Dong back a few steps, but that was all, and no additional damage was caused. If this attack had hit Tang San, it would have been enough to crush him into powder.

However, Si Yun could clearly see that the dark green aura on Bibi Dong had dissipated slightly. He had a keen eye for investigation, so he definitely couldn't be wrong.

Before the tentacles were retracted, Bibi Dong's figure appeared in front of him again. Si Yun's right palm hit down directly, and the Dark Gold God-Teasing Claw was activated.

Bibi Dong responded with a palm strike, and the two of them took a step back after a palm strike. This palm strike also caused Bibi Dong's dark green divine power to dissipate slightly.

After confirming this, Si Yun suddenly understood that Bibi Dong was out of control now, but she should not have reached the level of Tang San. It was estimated that she would be able to return to normal after consuming a certain amount of Rakshasa power, but he didn't know how much it would take.

Five minutes later, the mechanical armor on Si Yun's body had become tattered. If this were in the game, he would at least have a damaged skin.

And Bibi Dong's Rakshasa power has been consumed a lot.

Seeing this scene, Si Yun felt helpless. At this rate, before Bibi Dong's Rakshasa power was completely consumed, he would be beaten to death.

And just after a brief pause of one or two seconds, Bibi Dong's Rakshasa power actually recovered a little bit.

Noticing this scene, Si Yun, who originally wanted to defeat Bibi Dong by a protracted battle, instantly became clear-headed. He gathered all the remaining soul power in his body and launched the Dark Gold God-Teasing Claw. The terrifying giant claw fell. Even Bibi Dong, who was blessed with the power of Rakshasa, had no way to avoid such an attack. By the time she reacted, the giant claw had already landed on her.

After this claw, Si Yun immediately used the Source of Green Vine for the first time. In an instant, all the soul power in his body was restored. Then he continued to rush towards Bibi Dong. At this time, Bibi Dong's Rakshasa power had been consumed a lot.

A hint of clarity returned to his eyes.

"Si Yun."

As the familiar voice came, Si Yun's movements stopped for a moment, but the next second, Bibi Dong's eyesight completely recovered, and she landed a claw on Si Yun, knocking him out directly.
