The two of them searched again, and there were definitely no other buttons or anything like that.

Tian Bule frowned and said, "It doesn't make sense, how can there be no switch?"

The red lady sighed: "Maybe it can only be opened from the inside." ”

Tian Bule patted the red lady's head and said, "You don't want to think about it, if you can only open it from the inside, then how can those traps and night pearls be placed outside?"

The red lady stuck out her tongue and said, "With the son, the slave family is too lazy to use their brains." Anyway, it's okay, I'll take down a few of the night pearls on it first. As he spoke, he took out a dagger, jumped onto the cave wall, and quickly cut down five night pearls.

Tian Bule turned his head helplessly, continuing to look for a possible switch, and his eyes suddenly fell on the steel ring on the door.

The red lady hid the night pearl, followed Tian Bule's gaze, looked at the steel ring, and said in surprise: "I finally remembered." The owner of the door once told me that the steel ring is also a way to open the door. However, doors that generally use this method of opening the door will definitely be equipped with a hidden device. If the technique is wrong, the mechanism will be triggered, and the consequences will be unpredictable. "

Tian Bule didn't dare to open the door rashly for a while, and said, "Then is there a way to test the correct opening method of this door knocker?"

The red lady shook her head again.

Tian Bule's heart was crossed, and he suddenly reached out and held the steel ring.

The red lady was startled and said, "Son, what do you want to do?"

Tian Bule said with a solemn face: "Since I don't know how to open the door, I can only take a risk." Without waiting for the red lady to provide advice, she pulled the door knocker hard, revealing the steel cable connected to the steel ring.

The red lady said happily: "Childe, we have succeeded!"

Tian Bule said in a deep voice: "I can't pull it backwards anymore, it seems that I still need to turn it." Now it's up to you to decide whether to twist to the left or to the right, my luck won't be good tonight, it's up to you. "

The red lady lost her voice and said, "Childe, it's too risky to do this, isn't it?" and then said carefully: "Then turn left." Childe, you have to be careful. "

Tian Bule cautiously swapped his left and right hands and turned the door knocker. By the third turn, there was a "yes" sound from the steel door, which was crisp and loud.

The two of them froze, raising their vigilance to the peak.

Tian Bule laughed and said, "It's done!" He tried to push the steel door with one hand, and sure enough, he opened it with his hand, and opened the door along the steel cast sliding ball of the ground rail.

Another corridor came into view, and the end was submerged into the darkness, making it difficult to fathom the depth of the distance. But the air is fresher.

He was about to step through the door when there was a sudden noise.

When the two of them changed color at the same time, the change came suddenly.

Ten and five feet of steel arrows about the thickness of a long thumb seemed to shoot haphazardly from the darkness at the other end, and the sound of breaking through the air brought a fierce whistling sound, which was even more piercing in the silent underground corridor. Fill the space of the corridor that only allows people to stand, unless the two of them can become as thin as paper, they don't want to avoid it.

This kind of super power crossbow launched by the machine is a hundred times more powerful than the crossbow arrows issued by ordinary crossbow bows.

The red lady behind Tian Bule was already prepared, and with a coquettish shout, she waved out two long sleeves with both hands, and spun at high speed, forming a round shield in front of Tian Bule.

Unexpectedly, the crossbow shattered the cloth shield like a piece of paper. The red lady hurriedly withdrew her long sleeves.

However, Bu Dun still slowed down the speed of the crossbow.

The imperial sword that Tian Bule specially brought came out of his back, took a step forward, and shouted urgently: "Don't touch it hard!" Since the dragon sword has become his symbol, in Linzi, he only dares to carry the imperial sword with him.

The red lady and him have a good tacit understanding, and they have reached the realm of heart-to-heart. When Tian Bule's long sword attacked, she waved her long sleeves and swept the two powerful arrows flying from the right side.

"Ding ding" twice, Tian Bule's long sword hit the two powerful arrows that shot close to the ground. The Red Lady struck two arrows higher up, and the other six arrows whizzed above them, dangerously dangerous. Both of them used unloading techniques, causing the arrows to be misaligned and staggered. The remaining momentum is not stopped, and it is forced to break the wall and go deep into the Yingcun!

Think about the hardness of granite, and imagine the power of a strong arrow. Tian Bule's two arms were sore, and he didn't feel it. The Red Lady's own weapon is flexible, but it looks much better than Tian Bule.

Seeing that the tail of the arrow was still shaking, Tian Bule couldn't help but feel a little afraid. If there is

"Peng"!

The iron door closed behind the two of them, and it was locked with a "click".

Tian Bule and the red lady glanced at each other, and now there is only one way in front of the two, that is, to keep going, otherwise they can only wait for death.

As if history repeats itself, a long corridor stretches forward, ending in the misty light of the night pearl.

Tian Bule took a deep breath and quipped to the red lady: "You don't still want to dig up those night pearls, do you?"

The red lady's face turned red, and she didn't follow: "The slave family also wants to prepare the night pearl for the son." ”

Tian Bule took advantage of the faint clear light to carefully examine the ground and said: "See, the ground seems to be made of two different shades of gray bricks, which is different from the corridor just now. "

The red lady said nervously: "It's not good, there must be a trap!"

Tian Bule rolled his eyes, isn't this nonsense? He touched his chin and said, "The trap should be on the color of these bricks, the key is to step on dark bricks or light bricks?"

The red lady stretched out her foot and tapped on the dark brick, and said, "Hey, the dark brick has a little floating feeling." "

Tian Bule saw that the red lady didn't touch the mechanism just now, and said, "It seems that there is something wrong with the dark bricks." I'll try the light one. He stepped on a light-colored brick, stood still for a moment, and said, "It's okay with the light-colored one, let's go!"

The two of them stepped on the light-colored bricks step by step, about fifty stops, under the reflection of three night pearls in each of the left and right two rows, it was really a door, there was no steel ring, only a round button, the edge of the cloth was engraved with a number, a total of forty-nine grids, and there was a red dot engraved on the door wall above the button.

Tian Bule frowned, and he didn't know what to do for a while.

The red lady stepped forward and looked at the button carefully for a moment, and said, "I know this." The owner of the door once said that this is called 'heaven and earth lock', and the words of unlocking pay attention to 'heaven and earth two, heaven and earth four', and each step must meet the number of obstacles. When the correct tick is touched, it makes a different sound. "

Tian Bule praised: "You are finally a little enlightened." You tell me how to open it, I'll try it. "

The red lady said thoughtfully: "'Heaven and earth are two', the sky turns to the left, turns seven o'clock, turns fourteen o'clock on the right, and then turns back to twenty-one." "

Tian Bule squatted down and slowly twisted the knob. When the twenty-first tick passed the red dot, there was a slight abnormal sound, but if Tian Bule had not paid attention, he would have missed it. Tian Bule cautiously pressed hard, making a crisp sound of "yes".

The red lady murmured again: "The ground turns to the right, to forty-seven degrees." "

Tian Bule twisted the switch back in the opposite direction, and when it reached 47 degrees, the abnormal sound started again, and when he pressed it, it was another sound, and he continued to turn right to 47 degrees and press it again.

"Click"!

The steel door opened in response, and golden light came out of it, and the two of them suddenly couldn't open their eyes.

What appeared in front of the two of them was a treasure trove of gold that countless people dreamed of. Mountains of gold are piled up in underground treasure troves that shimmer with a dizzying glow under the illumination of dozens of night pearls
