The old man smiled when he heard this: "Even when facing multiple masters, they will miss some opportunities because they can't communicate information, but the twelve colors won't, they can not only seize opportunities, but also create opportunities, because they are one, I think even if they are their masters, they are far from being the opponents of their combination." ”

Dugu Yan nodded in praise, and the old man continued: "If you want to defeat them, you may still have to rely on the joint efforts of several people, and you may be able to do it." ”

Dugu Yan frowned and pondered: "If the three evils are repeated, maybe the power of a battle, but ......"

The old man smiled: "Perhaps, you can also have a powerful helper." ”

Dugu Yan asked, "You mean her?"

The old man nodded and said, "Yes, her swordsmanship can just complement you, but her foundation is very weak, so she may not be ......."

"It's not weak, she's not weak......" Dugu Yan didn't wait for the old man to finish speaking, and replied in a hurry.

The old man shook his head and said with a wry smile: "It's a pity, if it's just like this, it's not enough. ”

Dugu Yan's face was full of surprise and asked, "Do you want to make a move?"

The old man shook his head and said, "That day, I saw her sword. ”

Dugu Yan said: "Whose sword?"

The old man said, "Of course it's your sweetheart." ”

Dugu Yan said, "What's wrong with her sword?"

The old man shook his head, was turned away, and said, "Come with me!"

One old and one young, one in front of the other, left deep and shallow footprints on the snow. Across most of the mountains, a raised rock appeared in front of him, like a wounded hunter, crouching on the snow.

Going around the front of the "Hunter" and coming to its back, there is a dark hole that does not seem to fill or clog it with snowflakes.

The entrance of the cave is not big, but there is a hot current, which comes up from below, and Dugu Yan finally understands why this narrow hole is not blocked by snow.

No amount of snow melts when heated, turning into water and flowing elsewhere.

Dugu Yan looked at the cave and asked, "This cave should be able to lead to other places, right?"

The old man nodded and said, "This cave is connected to a low water vein, and it can indeed lead to other places, but there is no land route in it, and it is very narrow, and it is full of water in the depths, even your father can't pass through, let alone others." ”

Dugu Yan said: "You brought me here, is there anything you want to do?"

The old man laughed and said, "The secret treasures that your father left for you are all here!

Dugu Yan frowned and went into the hole. At first, the cave was pitch black and he couldn't see anything, but then he slowly adjusted to the darkness and began to see a small stream of water, presumably from the melting of the snow around him.

Follow the direction of the water and keep moving forward, which is also the only road in the cave, a narrow dirt path. Strangely, these melted streams were very close to the dirt road, only a ruler's distance, but the land was dry and not muddy.

The deeper you go into the cave, the warmer it gets, and the more humid the air becomes.

Dugu Yan wanted to light the fire fold to explore the way, but the humidity of the air at the moment made it impossible to ignite the fire fold again.

In this way, after walking for about half a mile, Dugu Yan looked back, the old man did not follow, and said in his heart: "He said that there is a secret treasure left by my father in this cave, let me come down and get it myself, but he didn't tell me what the secret treasure is, nor did he tell me where the secret treasure is, is he playing tricks on me?"

As I thought about it, the narrow road suddenly widened, but the air was filled with mist.

The reason why he could see the fog clearly was because there was light. The road before me came to an end, and in its place was a lake of red light and water, and the water was steaming upwards, and the cave was even hotter, like a giant steamer.

Dugu Yan stretched out his hand to the surface of the water and wiped it, the water was piping hot, and at this temperature, when ordinary people went in, it became boiled human flesh. No wonder the old man said that he couldn't even ask the emperor to pass.

"How can such hot water pass through?" Dugu Yan felt anxious in his heart, and secretly thought: "Could it be that the secret treasure left by my father is not in the water?"

He returned along the same path again, and when he looked carefully on the way, there were naturally formed rocks on both sides, and there was not a trace of artificial carving, let alone mechanisms, and there were no secret texts or anything like that.

Dugu Yan felt strange in his heart, and reached out to the place where the meltwater flowed beside him. The melted water was cold, and he thought to himself, "If it weren't for this cool water flowing into the cave, I am afraid that this hole would not be able to stay alone." ”

In desperation, he walked in along the water again, back to the "lake" that shimmered red, and this time, he could only take it a try, strip naked, and explore in the hot water.

The depth of the water was hotter than he imagined, Duguyan held his breath and dived into the water to observe, but unfortunately the water was too deep, although he could clearly see the red stones below, but he couldn't touch it. The reason is that the depth of this water is about a kilometer, whether it is in that era or this era, with only a physical body and no tools, wanting to dive into thousands of meters of water is tantamount to a fool's dream, even if it is a cultivator of Qimen Technique, the ability to practice breathing in the water is by no means shallow to the bottom of the water thousands of meters deep.

Dugu Yan was tentative for a while, and quickly closed his eyes. The boiling hot water made his eyes feel severe pain, and although the rest of his body was not suitable for it, it was not as fragile as his eyes.

He hurriedly swam up, keeping his head out of the water, and then continued to swim forward. After swimming for a while, the surroundings became narrow again, and there was only one waterway that could only be allowed to pass through one person, and the further forward it went, the narrower the waterway became, and the height became lower and lower.

The road suddenly came to an end, and the face was as smooth as a cliff, only in the middle of the cliff, a small flag was planted, and under the flag was a circular hole in the water, and only one person could be stuffed in.

- This may be the real reason why the emperor can't pass. Dugu Yan never had the courage to go into the cave to explore, because once the hole was deep and long, he would suffocate and die inside.

As soon as he stretched out his hand, he pulled down the small flag, only to see that one side of the flag read: "Ask the emperor to visit here, and those who get this flag will also be after my Dugu clan! ”

On the other side of the pennant, there are dense small characters written on it, and the light in this hole is dim and it is impossible to see clearly. Dugu Yan held the flag in one hand and swam towards the shore.

When he got to the shore, he still couldn't read the words on the other side, so he took the flag and walked in the direction of the entrance of the cave.

Then the sunlight that shone into the cave and looked at it, but the small words on the flag were still not clear. Out of the hole, he stood in the sun, but the words were still unclear.
