Here is the translation into English, preserving the narrative flow and detail of the original script:
When Dev tried to return his face to normal, Direction's voice came: "There is some information you should know before taking off the mask. You can only wear the mask for 24 hours, after which there will be a 20-minute cooldown. That means if you take off this mask now, you can only use it again after 20 minutes."
Dev thought to himself, if I take off this mask now, I won't be able to wear it again right away. But Dev thought, since I've already spent the money, I should eat the full meal. Dev decided, I will only take it off after 24 hours. He decided to remain in the guise of that hero.
Now he opened the system, where he saw his information. He moved the system panel aside and checked the system coins. The number of coins had now reached 570.
Dev said, "Well, I killed two knife-throwers and one masked demon, so the total number of coins should be 520. Is there a mistake?"
Direction's voice came, "Absolutely not, you also discovered a quest, 'Ruins'."
Dev remembered, "Yes, 50 gold coins were for finding the ruins." He felt a little embarrassed that this hadn't been on his mind. Dev said, "Never mind, let's move on now."
He didn't go inside the cave; instead, he thought that he should go to the cave visible in the other direction, because the dangers here were beyond his capacity. And who knows, in this form, Manasdev Khurana might not recognize him and, instead of helping, might attack him face-on, mistaking him for a stranger. He thought he would come here later.
Dev exited the cave and looked at the door on the other side. The leader of the demons had left that cave because he hadn't felt any demonic energy from that side. Instead, the demonic energy was strongest on this side. But Dev was now about to go this way.
On this side, the leader of the demons reached a very large place—the farthest end of this cave, beyond which was a large pond. The color of this pond was purple, and in the middle of it was a place like an island. On the island, a skeleton could be seen, which was three times larger than a human. In the chest of that skeleton was a stone heart. Near that skeleton, a snake sat coiled up.
All these demons seemed very happy seeing this thing; although they are semi-demons, they are still demons. All of them were saying, "We have found the demon heart, now we will bring it to life. Now there will be a real demon in our family. No one will even dare to confront us."
Although they were all happy, the demon leader's attention was elsewhere—on the snake near the skeleton. This is no ordinary serpent, and this pond is no ordinary pond either. If this snake attacks with its venom, it's extremely dangerous. It seems it must have come into this cave a few years ago and was drawn here by this pond. Actually, this pond is poisonous, and anyone who comes into contact with it can fall victim to a terrible disease and die instantly. This snake, too, was no longer less dangerous.
That leader told one of his men to go from the middle to the place with the skeleton. That man said "Yes" to his leader and started moving forward. Perhaps he was unaware of the danger. As he jumped to set foot on that place through the purple water, he froze mid-way, and his entire body turned blue. He dissolved right into the water.
That leader said, "So this is true, I wasn't wrong."
He didn't care about the people working under him. He had done such things before. When he was 20, trapped in a trap with his friends, he used all his friends as a ladder and escaped. For him now, this was normal. He thought, if I jump directly from here to that place, my defense will be low, and that snake could bite me.
He picked up a very large stone from nearby and told his men to take off their clothes and make a rope. After that, he tied the rope securely to the stone, held the end of the rope, swung it, and using his strength, threw it upwards toward the skeleton. The speed of that stone became so great that the demon leader, holding onto the rope, began moving forward through the air in that direction. Midway, he let go of the rope, enlarged the Rubik's Cube in his hand into a spiked hammer-like weapon, and slammed it directly onto the snake.
But before his weapon struck, the tied stone he had thrown hit the upper wall of the cave at high speed, waking the snake from its sleep.
Meanwhile, when the red-haired Malan Khurana said to the cultivator in front of him, "Do you want to get beaten outside this hospital room or right here?" saying this, he looked at the masked man and smiled.
That masked man said to himself, "You've gotten me killed, this one is a cultivator." He said, "Now that I'm here, I might as well give it a try."
He extended his hands to strike the red-haired man. But when he was halfway, Malan Khurana moved his hands, and within moments, the masked man's vision began to blur. The masked man quickly took out a teleportation circle from his possession and disappeared.
This teleportation circle could teleport him 50 meters away from that spot. The man appeared on the road far from the hospital and spat blood from his mouth. "Ah! If I had stayed there any longer, I would surely have died." The attack had already hit him before he could even see it.
He moved on, having failed, and reported the mission failed. However, after going a short distance, he collapsed right there. After a while, the red-haired man appeared, lifted him onto his shoulders, and vanished.
Meanwhile, the man who received the mission failed message said, "This is impossible. It seems he actually had some connection to the Khurana family."
