"Oh, we're so lucky!" Roy said with a smile: "Let's go in and take a look." After that, he walked into the secret room first.

Although the secret room is not very spacious, the air is filled with rich oxygen, and the sound of water droplets vaguely comes. It seems that this is indeed a hot spring pool, but Roy is not concerned about this matter now, but the paintings hanging on the stone walls around the secret room.

These stone walls are painted with images of animals or beauties. Whether it is a noble gentleman wearing gorgeous costumes, a battlefield warrior with naked chests, or a naked man and woman. Some of these people are dancing swords, some are dancing, and some are lying in a bathtub to drink and eat meat. From the expressions of these people, it can be seen that they seem to live a very happy life and have not encountered any suffering.

The most eye-catching among these people is naturally the portrait. The protagonist in the portrait is a thin and handsome young man. He sat at the head of the bed holding a long bow, his mouth slightly raised, and a playful smile on his face, as if he was mocking something, his eyes were full of jokes and coldness.

Roy looked at the oil painting on the wall. The oil paintings were rich in content and contained many details, including how this handsome young man created flames, how he shot his enemies with arrows, and how his parents died tragically at the hands of the enemy.

Roy frowned and silent.

In this oil painting, the painter deliberately used an exaggerated brushstroke to describe the handsome young man's powerful martial arts, and at the same time exaggerated the despair of his father and mother before his death.

The style of this oil painting is very different from the styles of the painters Roy usually sees. Not only is the color tone more vivid, but the style of painting is also strangely changed. The use of lines and the matching of colors seem wild.

"What are you looking at?" Isaac asked. He also looked at the paintings on the wall, but he did not find anything strange about these paintings.

"Oh..." Roy retracted his gaze, "This is a historical legacy of the ancient civilization, and it should be their mark."

"Oh, so that's it..." Isaac nodded.

He then asked, "How did this painting be preserved to this day?"

"This painting has been stored here for at least 500,000 years, and it must have used the technology of ancient civilizations." Roy replied.

"What a magical thing... it's far more than us humans." Isaac exclaimed.

"Are we going to continue exploring ahead?" Roy asked.

"Well, I heard there are treasure secrets hidden here, but we must be careful and never break into some dangerous areas by chance." Isaac reminded.

"I know, don't worry, I won't break into the penalty area." Roy smiled.

The two of them led the expedition team to continue to move towards the depths of the cave. Along the way, in addition to the oil paintings on the walls, they could occasionally see other valuable things. However, Isaac was not interested in this, and his purpose was not these, but something that ancient civilization recorded technology.

After passing through several forks, everyone arrived at a huge hall. In the center of the hall was a round platform about twenty meters high. Next to the round platform were more than a dozen rows of wooden racks, and various types of equipment were placed on each rack.

Roy and others stood at the door and observed for a while, and decided to venture into the hall to take a look.

Roy and Isaac took the lead in walking into the hall, while other expedition members followed behind.

"Be careful of the soles of your feet." Andrew, who was walking at the end of the team, reminded. As soon as he finished speaking, a rope ladder suddenly fell down.

"Damn it, please dodge it." Andrew hurriedly grabbed an expedition member and pulled him apart, then reached out and grabbed another person and threw him out.

Both fell to the ground, but fortunately they were not injured and avoided being tripped.

Just as Andrew breathed a sigh of relief, he suddenly felt a chill on his back, and then he lost control and flew out. He turned his head in the air and saw that he had actually flew to the top of the hall!

At this time, Andrew's legs were still hanging in the air. He struggled desperately, but to no avail.

At this moment, Andrew felt himself hitting a soft elastic wall. Then he fell into a coma and was unconscious.

"Andrew!" The others rushed to him in shock, but found that Andrew was unscathed. He was just in a brief coma.

Everyone hurriedly dragged Andrew to a wooden room and checked that his physical condition was not in place. Everyone breathed a sigh of relief, but they still looked at Andrew in a worried state.

"What will happen to him, will he?" a timid young man asked in a low voice.

"Don't worry, Andrew will be fine." Roy patted his shoulder and comforted him: "He is just too tired, and he will be fine when he wakes up."

Everyone showed a relief expression when they heard this.

"So, which fork will we go to next?" Isaac said to others.

"I recommend choosing the right road," Roy said. "We need to find information in the ruins so that we can figure out what the ruins are for."

"Okay, I agree with you." Isaac shrugged.

So Roy led everyone to continue along the corridor. The interior of the underground palace was very wide, the corridor was curved and long, and there were many murals on the walls on both sides.

Since all the humanoid objects on the mural were wearing masks, everyone did not carefully identify the content of the mural, but just hurriedly browsed and left quickly.

On both sides of the corridor are walls made of heavy stone bricks, and there are many carved patterns on the stone bricks, but most of the carved content has been completely destroyed by the corrosion and decomposition of time.

The light here is not caused by the lights of candles, but the faint white light emitted from the stone wall.

This white light is not dazzling. On the contrary, in a dark environment, this light seems to add some mysterious charm to it. Every stone brick in this underground palace is shining with a white luster, and even the dust in the gaps in the stone bricks cannot escape this layer of light. Under the reflection of the white light, the dust even reflects crystal clear light, like starry debris.

"What's this..."

"Oh my God! So beautiful."

"I've never seen anything so beautiful!"

This scene really makes people scream.

Not only are there many such murals on the surrounding walls, but even the ground and the ground are inlaid with a large number of these white crystals, shining with faint light like night pearls. Moreover, the size and color of these crystals are similar, and even the patterns on them are very consistent.

"What are these?" Isaac squatted down and grabbed a crystal and studied it for a while, saying, "It looks pretty, but it doesn't seem like a magic element, nor does it look like a gem produced in metal veins."

"We'd better be careful," Roy said. "Although they don't look like something dangerous, who can guarantee there are no hidden dangers."

Isaac nodded and said, "That's right, this place is really full of weirdness."

After discussing for a while, everyone finally decided to continue searching according to the original plan. After all, their time is limited and they have to obtain as much information as possible.

"Then... let's start from here." Isaac said after making the decision, and he planned to explore the corridor.

The team members followed Isaac to the house with murals, where they saw another arch. This time there was no mural on the arch, but it was still open.

"Get in?" Roy asked as he looked at Isaac.

"Since you've come here, you have to see enough." Isaac said, then pushed open the arch and walked in.

Roy and others immediately followed him, and after passing through the arch, they entered a spacious room surrounded by a circle of glass cabinets, filled with all kinds of things.

"Is it a storage room?" asked a team member.

"I don't think so, it should be a warehouse or warehouse that stores weapons and equipment." Isaac said.

Everyone walked around the glass cabinets and came to a door. The material of this door was very solid. Isaac tried to knock hard, but failed to open the door.

"It seems that the key should be in this underground base." Isaac said: "Do you have a way to open the door? If so, please let me know."

"I'll try it out," said Andrew. "You retreat to the side and I'll pry this door open."

"Oh, OK." Isaac nodded.

After taking a deep breath, Andrew pounded the hammer door hard.

"Bang-Click..." With the dull sound, Andrew's fist hit the door lock, and immediately smashed the door lock. He withdrew his hand, twisted the door handle hard, and opened the door.

"How do you know it's the keyhole?" a team member asked in confusion.

"This is an old craft." Andrew laughed and said, "You don't understand."

Everyone shook their heads and sighed. Andrew's technique is indeed quite skillful, but his technique is only suitable for tomb robbers. If he really asked him to open the door lock and other tasks, he would probably not be able to do it.

Andrew took the lead in stepping across the threshold and looked inside. There was a huge room inside. The room was filled with huge shelves. There were all kinds of weapons on the shelves, including swords, guns, swords, halberds, axes, hooks and forks, and even crossbows.

At the most conspicuous place, there were several giant weapons that looked extremely sharp, which made Andrew's eyes slightly widen. He quickly walked to the weapon frame, picked up a sword, and pulled it out.

"This is..." He raised the sword and waved it left and right, then frowned and said, "This sword is so hard!"

"What kind of sword is this?" another team member asked curiously, "Have we seen it before?"

"Well... I don't seem to have seen it in my memory, but... the shape of this sword is very unique." Andrew touched the sword body and said, "I have seen this sword before."

"Oh?" Isaac asked with interest: "Have you ever seen such a weapon? Where is it?"

"It's...it's in my dream." Andrew replied, "But...I can't remember, I only saw this sword in a vague way..."

Professor Isaac saw several people discussing with a sword, and his forehead was so anxious that it was smoking.

He shouted loudly: "Roy, hurry up, our mission is to find the technological information left by ancient civilizations, and don't waste time on these irrelevant things."

As soon as Professor Isaac finished speaking, a slight sound suddenly came from the corner of the room. The sound sounded particularly vulnerable in the empty room, making everyone alert.

"Be careful!" Isaac shouted softly and rushed over, lifted his foot and kicked a box close to the wall. The box rolled out instantly, hit a stone wall, and then fell to the ground.

"My God!" A team member immediately screamed when he saw this situation, and then hurriedly took several steps back.

When everyone heard this, they immediately turned their heads to look at it. They saw a monster curled up in the rolling box. The monster looked extremely ferocious and terrifying. The skin was green all over, and large pieces of black scales grew on their backs. The eyes were strangely purple-brown, which looked very ferocious. Large drops of mucus were flowing out of its mouth, dripping onto the floor and making a sizzling corrosive sound.

It was still half open its eyes, as if it had not realized that it had been attacked, but it was just a brief loss of consciousness. It immediately stood up, let out a low roar, and stretched out its body.

"It's a snake." Andrew said after observing it carefully for a few seconds: "It seems like it's trapped somewhere, are we going to kill it?"

"I can't eat such an ugly snake, and... there are still a bunch of messy bones here." Isaac glanced at the room with disgust and finally found several corpses in the corner.

Isaac's eyebrows twitched twice: "...We must leave quickly, there must be something wrong here."

They immediately accelerated their escape. After passing through this passage, they came to another road and successfully found an iron gate.

"Open the door." Isaac ordered.

"Okay." Roy ran over immediately, pulled the door bolt, and then pulled it hard. As he tried harder, the iron door was slowly pulled down. At the same time, he also saw clearly what was inside.

"Oh, what is this?" Andrew opened his mouth wide in surprise.

Behind the iron gate, there was a huge cage. The height of the cage was more than five meters and was in the shape of a step. All of these steps were surrounded by thick steel fences, and there were thick iron columns between the fences.

"What's this? A cell that imprisons people?" Andrew couldn't help but mutter.

"Who are you?" Suddenly an old and low voice came from their flanks, scaring them to the side immediately jumped aside and avoided the thing that suddenly appeared behind them.
Chapter completed!
