Early the next morning.

When we woke up, Han Jin and his people were already ready to go, and when we packed up our things, the others were still motionless, presumably the palace lord warned them yesterday, don't mess with anything here, the main reason why the gold lord asked Han Jin to take us here should be that we take others to the Kunlun Golden Gate.

"The pattern here is not in harmony with the entire Golden Gate, there must be a blocked passage, if it is an ancient tomb with a brick and earth structure, I can still tell, and the age here is too old, I can't even deduce the age, let alone the style of construction." I put my bags on my back and turned to the palace lord and Tian Ji and said. "It's up to you here."

"I'm good at digging graves, but these three ice walls are exactly the same, and the ice cubes in the whole ice room are dull and different colors, and unlike the tomb, you can still distinguish the direction and the passage in and out." Tian Ji shook his head helplessly.

"I'll try."

After the palace lord finished speaking, he walked to the three ice walls, gently pressed his hand on the thick ice, and then knocked on the ice with a shovel, the palace lord closed his eyes and stared at nothing, I only saw five fingers constantly touching slightly, when he walked to the ice wall on the right, the palace lord repeatedly knocked twice, and his eyes suddenly opened.

"I don't know why the impurities in these ice walls are different, but the tremor behind this ice wall is weaker than the other two, indicating that the back of the ice wall is hollow, and the passage is behind this ice wall." Gong Jue nodded affirmatively.

"Carve a path through this ice wall." Han Jin commanded his subordinates.

The rest of the men immediately took out their tools and began digging into the ice wall, which for a whole morning was less than twenty centimeters deep.

"It can't go on like this, these ice walls are eternal ice, extremely strong, according to this progress, it is estimated that it will not be able to penetrate in ten days and half months." I shook my head and told everyone else to stop.

"I can feel that this ice wall is definitely more than five meters above through the shock, not to mention ten days and a half months, even half a year." Gong Jue said with certainty.

"Then don't dig at all, it's a waste of time anyway, our remaining dry food, save a little to last for more than ten days, and we are already starving to death before the ice wall is opened." Tian Ji sat against the ice wall and picked up the ice that had been chiseled, and threw it to the opposite side in a boring manner.

"Take the explosives, and blow the passage out anyway." Han Jin instructed his men.

"You can't use explosives! The Kunlun Golden Gate is built with ice blocks, like building blocks on top of each other, you blow up the ice wall will affect other ice blocks, this is the lowest layer, are load-bearing ice blocks, once shattered, the entire Kunlun Golden Gate will collapse. I hurriedly stopped.

Lofty!

A high-pitched, shrill sound suddenly echoed through the ice chamber, and then we heard the sound of the ice breaking deep in the ice, and I don't know where it came from.

The sound pierced the eardrums, and we turned around to see Tian Ji raise his hand, looking at the seven bronze bells in the middle of the ice room with a stiff and dull expression.

"I ...... I didn't mean to, I didn't think the bell was so loud. Tian Ji looked innocent.

Our eyes fell on the seven bronze bells, and I paid attention when I came in, but there were no words or ornaments on them, and the craftsmanship was not clear, so I didn't pay much attention to them.

Gong Jue slowly walked to the bronze bell, looked back and forth for a long time, and asked Tian Ji behind him: "Which bronze bell did you hit just now?" ”

"I don't know, I just threw it away." Tian Ji stood up and shook his head.

I looked back at the three ice walls, and suddenly realized that all the mechanisms of this ice room are based on the principle of resonance, the so-called resonance, to put it simply, when an object vibrates and causes other objects to vibrate, at the resonance frequency, a small periodic vibration can produce a large vibration, and the power generated is amazing.

These walls of ice have different colors due to the different impurities inside, and the resonances in them are also different, and when the bronze bell is struck, the sound produced is the same as that of one of the ice walls, which directly shatters the ice wall.

"That's not easy, knocking the bronze bell next to each other can shatter the ice wall blocking the passage." One of them said loudly.

"There are seven bronze bells, which means that there are seven different resonances, and if you knock the ice wall in the wrong place, it will shatter, and the entire Kunlun Golden Gate will collapse with a bang." Han Jin glared at the man with a gloomy face. "Only one of the seven bronze bells can open a passage, and only once."

Han Jin was right this time, the ice cube thrown by Tian Ji fortunately hit the bronze bell, if it hit the pendulum below and hit the bronze bell Judging from the sound of shattering just now, we are afraid that we have been buried under the iceberg.

This belongs to the category of tricks, Tian Ji and I both looked at Gong Jue, he rubbed his forehead and said, using music rhythm to do tricks is also a common way, his mastery of music is perfect, but this kind of trick has been beyond the scope of what he has learned.

"This ice wall is intact, which means that no one has ever entered it." Tian Ji walked up to us and lowered his voice. "What his master can't do, don't force the palace lord."

"What do you mean by that?" The palace lord glanced at Tian Ji, and his arrogance came up again.

"You don't know what to do." Tian Ji's eyes widened. "You can do it, you can come."

"It's not that he can't, he doesn't dare, everyone will be buried here, he doesn't dare to gamble with my and your lives." I smiled faintly and patted him on the shoulder. "As you said, listening to your master's words and sharing life and death with me, I am not afraid, what are you afraid of."

"Don't think about going back to the rest of the dry food, what are you worried about, you are going to die, I would rather die on the top of the Kunlun Golden Gate, maybe I can meet the gods." Tian Ji smiled indifferently.

Gong Jue shook his head helplessly, took a deep breath and picked up the ice cube from the ground, beat it into an ice pick with a probe shovel, walked to the bronze bell, carefully held the pendulum below, and then paused for a moment, calmly and gently struck the bronze bell with the tip of the ice pick.

The subtle sound was indistinct, and everyone even deliberately held their breath not to disturb the palace lord, he was completely using the orders he had trained since he was a child to identify the resonance between the bronze bell and the ice wall.

It took him three full hours to finish striking the seven bronze bells, and our feet were numb, and no one dared to move, and when the palace lord looked back at us, he had a feeling that he was about to collapse, and in such a cold ice room, his forehead was covered with sweat, and I knew that he was actually under more pressure than any of us.

"The fourth." The palace lord's voice hesitated.

"Surely you are the fourth?" Han Jin should have seen it too, and asked gloomily.

"I'm not sure, but I don't dare to try again, I can hear the cracking of these ice walls inside, and the consequences of spreading if they intensify." The palace lord shook his head slowly. "Only the fourth, I faintly hear the sound of shattering from the other side of the ice wall."

"Then the fourth, what are you hesitating about." Tian Ji asked.

"But when I struck the two, four, and five bronze bells, I heard voices from there, but the fourth one was more obvious, and I wasn't sure." The palace lord licked the corners of his mouth haggardly.

"It's decided, the three of us brothers will gamble their lives today."

I smiled faintly, knowing that Gong Jue didn't dare to ring the bronze bell, so I pulled Tian Ji and Gong Jue to stand together, and I didn't even think about reaching out to ring the fourth bronze bell, but at the moment when I was about to ring it, Gong Jue suddenly pulled my hand down and rang the fifth bronze bell myself.

Lofty!

The thick and low sound of the bell echoed in the ice room, and a huge cracking sound sounded immediately, and an obvious crack appeared on the ice wall in front of the passage, and the clicking sound kept spreading, and in an instant, the thick ice wall was torn apart and shattered into one piece.

The shattered ice was sinking rapidly, I heard the sound of rushing water, and when I looked down at the flowing underground ice, I hurriedly asked everyone to immediately pass through the ice floe that had not yet sunk, and when I passed through the broken ice wall, I found that the water was flowing down like a beaded curtain on the top.

Gong Jue walked over and was surprised to say that the mechanism here was simply ingenious, although the ice wall was damaged, it would be washed away with the glacier, and the water dripping from above would slowly re-condense into ice in the low temperature of the ice chamber until the water above was closed, and it would not be long before another impregnable ice wall blocked the passage.

"It looks like those people didn't pass through here forty years ago." Tian Ji said in amazement.

"I can do it, and of course she can do it." The palace lord nodded.

"By the way, you clearly said that it was the fourth, why did you finally knock the fifth?" I still had a lingering breath and asked curiously. "Didn't you say you're not sure?"

"I'm really not sure......" Gong Jue's expression changed from hesitation before to surprise.

"Not sure?" I looked at each other. "Not sure if you dare to knock?"

"I feel like it's the fifth......" Gong Jue rubbed his forehead, looking dazed. I...... I seem to ...... I once struck these bronze bells......"
