Althea and Lu winked at each other and charged towards the group of monsters in front of them.

Lu raised the black sword in her hand and slashed at the first few winged demons that rushed in front of her. These swords were fast and fierce, and they immediately cut off the bodies of the several winged demons in front of her. Then she sprinted again.

Arriving in front of a Winged Demon King, the Winged Demon King also noticed Lu's figure and stabbed Lu's body with a silver gun in his hand, but Lu turned around lightly on his heels and easily dodged this attack.

He struck, then jumped up and chopped off the Winged Demon King's head with a sword. The huge Winged Demon King, after losing his head, fell directly to the ground, and his body began to slowly dissolve.

Groups of monsters instinctively stepped back several meters after seeing Lu's shocking ability. It was obvious that the Lu in front of them was a huge threat to their lives. This made them change their target from Lu to

Althea stood aside.

There are still several monsters gathered next to Althea at this time. Although there are scattered corpses of several monsters lying at Althea's feet, they are not like Lu.

, can easily destroy so many monsters.

Althea kept waving her long sword, killing the demon dogs closest to her. Then, she activated the ice magic. With the activation of the magic, starting from Althea's side,

An ice storm blew up. This strong ice storm froze all the monsters approaching Althea into ice cubes. Lu found that only Althea and her side were not affected by the ice.

The attack of the storm.

"The precision is very accurate..."

Indeed, if they were not of high skill, it would have been impossible for the two of them not to be affected by the storm. After almost all the monsters were frozen, the ice storm calmed down.

"I can't tell that Althea-san's fighting method is so bold and unrestrained. It's really different from what she did in the simulation match."

"If it's normal times, I usually just use the same fighting method as during the simulation game, but if it's like this situation, I will fight like this now. After all, fighting is inherently flexible.

of."

Lu agreed with Althea's statement. Indeed, if you cannot be flexible and adaptable during battle, you will easily fall into a dangerous situation if you are too rigid.

"So, Althea-san, do you still want to open this box now?"

"Of course, the previous efforts were just for this moment."

Althea put away her sword, walked to Lu's side, and then squatted down to open the box.

"It's always the most exciting moment when you open a box like this."

Lu looked at Alsia's excited face and didn't know what to say. At this moment, Alsia had already opened the box. Lu was also curious, so she leaned down to see what was in the box.

.

But the result was beyond their expectation. Inside the box, there was just an old piece of paper.

"What is this? Don't tell me that you have worked so hard for so long to get such a piece of paper."

And when she said this, Alsia's face already showed a look of dissatisfaction.

"Lend it to me for a look."

Lu took the piece of paper from Althea's hand, but after observing it for so long, she saw that it was just an ordinary old piece of paper. In the end, Lu felt that she couldn't see anything no matter how hard she looked.

, decided to throw the paper away, but at this moment, he saw some words vaguely appearing on the paper.

Althea, who was next to Lu, also noticed the changes on the paper, and moved closer to Lu. At this time, the paper in Lu's hand, which was originally old, had black marks on it.

The words slowly emerged, but Lu had never seen these words before. Even Althea shook her head to express that she did not know such words.

"It doesn't seem like I got nothing." Lu put the piece of paper back into Althea's hand at this time.

"Yeah, I'm afraid that for some scholars who study ruins, this thing will make them ecstatic." Althea took the paper and stuffed it into her pocket.

Althea felt that there wouldn't be any emergencies now, so she planned to chat with Lu for a while. After all, she was full of curiosity about Lu.

"By the way, Lu-san, can you tell me now why you appear in the ruins?"

Lu didn't expect that Alsia would ask this question again at this time. If she made up a lie as casually as before, I'm afraid Alsia wouldn't believe it, so what should I say?

Just when he was worried about this, suddenly, the black sword he carried on his back began to vibrate again, and this time the vibration was far more intense than when he was in Alice's mansion before.

Finally, it even flew out directly from Lu's back, and then continued to spin at high speed on the ground.

Althea could be said to be stunned at this time. After all, the scene in front of her was really unbelievable.

Lu didn't know exactly what this black sword was going to do, but he had an intuition that this black sword must be related to the ruins, otherwise, it would not have guided him to the ruins. Moreover, it was still like this.

It was late at night before he was guided here.

The black sword rotated faster and faster on the ground, and Lu and Alshia stared at the black sword in front of them. In the end, the black sword floated into the air just like before, and this time, from

A layer of strong black energy began to emerge from the black sword's body, and this black energy was filled with an ominous feeling. It didn't take long for the black sword to be completely enveloped by this layer of black energy.

"What the hell is going on with this sword?"

"I don't know either, but I always feel like it wants to tell me something."

And just as Lu guessed, the black energy covering the sword began to slowly dissipate, and after dissipating, the black sword pointed directly at a place in this room.

"What does it mean?"

"Could it be..."

Althea seemed to have grasped something, and then walked to the direction indicated by the black sword, which was behind a wall, and then tapped the wall a few times with the back of her hand. And she quickly

I noticed that there seemed to be a hollow behind this wall.

"Classmate Lu, there seems to be a hollow behind this wall. Can you use this sword to destroy this wall?"

"Let me give it a try."

Lu grabbed the black sword suspended in the air, swung it at the wall pointed by Althea, and the power of the sword completely destroyed the entire wall.

Seeing the power of this sword, Alsia couldn't help but admire the power of this sword. If she had been struck by this sword, I'm afraid she would definitely die.

As the wall peeled off, the back of the wall was also revealed. But when they saw what was behind the wall, both Lu and Althea had expressions of surprise on their faces. Because behind this wall

Behind the wall is a mural, and the content painted on the mural is extremely familiar to Lu.

"Solomon Osiris..."
