Huang Hao's eyes moved in the space of the storage bag and soon fell on a golden key.

"It's it!" Huang Hao's heart moved, and a hint of joy appeared on his face. He was sure that this was the key, because he saw a line of extremely small words carved on the key, which were the characters in the underground palace.

With a thought, Huang Hao immediately took out the key.

With the key in his hand, Huang Hao felt his wrist sinking, and he almost didn't hold it in a daze, and he couldn't help but frown slightly.

This key is so heavy! I'm afraid that people with strength below the Golden Pill stage can't move even if they are in the Golden Pill stage. It's a bit difficult to pick up such a key. Of course, Huang Hao's Golden Pill stage is an exception and cannot walk according to common sense.

Holding the key in his hand, it actually emitted a bright light. At the same time, the small bulge at the keyhole on the door also emitted a similar light, as if reminding Huang Hao that the location of it was the location where the key was inserted.

Huang Hao's eyes were fixed, and he stretched out his finger to the small bulge. Suddenly, the small bulge sank into the door, and a round keyhole appeared in front of Huang Hao. Like the small bulge, the keyhole also emitted a faint glow at this moment.

Huang Hao took a deep breath, then hesitated no longer and gently inserted the key on his body into the keyhole on the door.

"Crazy--"

As the key entered the keyhole, Huang Hao turned around without waiting for Huang Hao to turn. When the key turned around three times, Huang Hao saw a strange scene. The underground palace texts on the gate suddenly lit up. After these texts lit up, without waiting for Huang Hao to react, a ray of light suddenly shot out and swept towards Huang Hao's eyebrows.

The light came suddenly and was fast, so Huang Hao was not prepared at all. When Huang Hao showed his warning in his heart, the light had already entered Huang Hao's eyebrows and disappeared.

At the same time, Huang Hao found that there was an indescribable connection between him and the door in front of him. Huang Hao seemed to have absolute control over this door. As long as Huang Hao thought, the door would open obediently.

"Huh?" Huang Hao's eyes suddenly moved and he looked at the location of the keyhole. He saw that the key that was just inserted into the keyhole disappeared at some point.

"Can this key be a one-time job?" Huang Hao secretly guessed in his heart. But then, he threw this idea out of the sky.

Now let’s enter the gate first and see what is in this cultivation room.

"Open the door for me!" Looking at the door, Huang Hao's thought moved.

The next moment, the gate was clicking, and the ancient giant beast that had been sleeping for a long time slowly woke up, like a relaxing muscles and bones.

"Crack--"

A sound of a slug sounded from the door, and the first gap finally appeared between the door and the wall. Then, the gap became larger and larger. Finally, after a "click", the door was completely opened.

A ray of light came from the door hole left after the door opened. Huang Hao's eyes were stunned.

"This is..." In horror, Huang Hao didn't care about anything else and stepped into this training room directly.

Just after Huang Hao entered the cultivation room, the gate closed with a "boom".

However, Huang Hao had no intention of paying attention to why the door closed on its own. At this moment, he was completely shocked by the cultivation room in front of him.

"This... this is too incredible." Huang Hao's eyes widened, as if he had seen something extremely unscientific, and he could just stuff an apple into it.

The next moment, Huang Hao reached out his hand, picked up a remote control on a table in front of him, and pressed it on the projector-like thing.

Yes, even the remote control and projector, Huang Hao did not expect that the room was not like the Demon Continent, but was similar to when Huang Hao was on Earth. Not only did there be a projector, but there was also a leather sofa in the middle of the room, and various objects with extremely modern materials, such as air conditioners, refrigerators, etc., which were all in one go.

If Huang Hao hadn't been convinced that he was in the ruins at this moment, he would have suspected that he was definitely not in the Demon-Captaining Continent, but in a mansion on earth.

This is too modern, even the tech otakus on earth may not have so many equipment.

What surprised Huang Hao even more was that there was a separate indoor swimming pool and boxing ring in this huge room.

"Didi--"

A crisp sound rang out from the projector, and then Huang Hao pressed the remote control and the projector responded.

With a "hula", a burst of energy suddenly evoked from the projector. As this energy was driven out, a ray of light fell on the front wall, forming a picture.

In the picture, a movie was actually shown.

Curiously, Huang Hao started watching. He wanted to see how the movies in this training room were different from those on Earth.

"Hey, it turns out that the people in the underground palace are no different from the humans here." Seeing that the character in the projected picture actually has noses and eyes and has healthy limbs, almost no difference from the people in the Demon Continent. However, the words said by the people in the underground palace in the movie are extremely difficult to speak, and Huang Hao could not understand at all.

If there were only words, Huang Hao was confident that he could understand the meaning through the Eye of Jishui, but the Eye of Jishui could only see it, but he would not listen. The young underground man in the projected picture kept talking nonstop, but there were no subtitles. In this way, Huang Hao only felt that he was blinded.

The projected image seems to be a romantic drama. In the image, a pair of outstanding men and women are affectionate with each other. Huang Hao directly pressed the remote control and turned off the projector. Suddenly, the training room became clean again.
