Wang Ke was not polite to them, and as soon as noon came, he immediately rushed into the formation, and traveled all the way, and soon reached the center of the formation, and stood in front of the cave again. Pen ~ fun ~ pavilion www.biquge.info

He didn't study this cave, but quickly used the trick of stealing the sky and changing the day, completely covering up his strength, and then he took a closer look.

The cave is on the surface, half a zhang square, like a well, looking inside, the black hole is bottomless, it does not look artificial, but it seems to be born naturally.

The Grandmaster can judge the distance by sensing the qi machine, but there are no living beings in this cave, and there is no qi at all, so if you want to know the depth, you can't do it by induction.

Wang Ke thought about it, took out the fire fold from his arms, lit it and threw it down.

I saw a little fire falling straight down in the darkness, getting smaller and smaller, and after five breaths, it fell to the bottom of the cave, and the flames were extinguished.

Wang Ke counted on his fingers, stopped after a while, and scolded secretly: "What is the formula for free fall, I don't remember it!"

After thinking about it for a long time, Wang Ke finally remembered, and put the time into it, the cave was about forty zhang deep.

As soon as the result was calculated, Wang Ke heard the wind rise behind him, and when he looked back, Hao Tianji had already arrived.

Haotian Ji suppressed his strength first, and then asked, "Is this the heart of the formation?"

"It's this hole, and I don't know what's down there. Wang Ke said.

"I thought it was a grave, but I didn't expect it to be a hole, and when everyone comes in, let's go down and investigate. Hao Tianji said.

The others entered one after another, and before the passage closed, all entered the formation.

Haotian Ji saw that everyone had arrived, and said, "This should be the remains of the Yin and Yang family, let's go down and have a look." Just in case, Uncle Taixu and I went down first. ”

I don't know the good luck below, Haotianji, as the strongest person, of course, has to go down to explore the way first, and the reason why he pulled up the Taixu real person is completely to avoid suspicion.

"It's good that if something happens, we can still take care of each other. "Taixu Zhenren answered.

Although the entrance to the cave is not large, it can accommodate two people, and everyone is fully prepared when they come, and ropes are naturally indispensable.

Xiao Qiang took out two rolls of transparent silk cord from the package, only the thickness of chopsticks, but it was made of silk, extremely tough, not to mention a person, even an elephant.

Don't look at the silk rope these days, it doesn't seem to be very long, in fact, each volume has a length of 100 zhang.

On the other side, Xia Bingyang took out two short sticks made of stainless steel, both of which were more than two feet long and the thickness of his thumb.

He threw it to the ground, and two steel rods were nailed into the ice, leaving only about half a foot outside.

Xia Bingyang clamped the steel rod exposed to the ground with his fingers, and with a gentle roll, the top of the steel rod was bent into a circle.

Xiao Qiang tied the silk rope to it and dragged it hard, and when she saw that the steel rod did not move, she also threw the silk rope into the hole.

Wang Ke said: "Actually, there is no need to be so troublesome, this hole is only about forty zhang." ”

Forty zhang deep, it is not a problem for Wang Ke, not to mention the two strongest great masters in the world.

"Are you going down?" asked Xia Bingyang.

"No, I figured it out. Wang Ke said.

"Nonsense, can you calculate the formation, can you still calculate this hole that is black?" Xia Bingyang said.

This is the old man, of course Wang Ke can't argue with him, so he only shrugged his shoulders and stopped talking.

"Be careful to sail the 10,000-year-old ship, and there is no harm in being more prepared. Hao Tianji said.

This cave is bottomless, even Haotian Ji doesn't dare to hold it up.

Two men each held a rope and jumped into the hole.

After a while, I saw the rope shaking, and Hao Tianji's voice came from below: "In the end, there is a big place inside, you all come down." ”

Everyone jumped down in turn, and found that, as Wang Ke said, it was only forty zhang deep.

Xia Bingyang patted Wang Ke on the shoulder and said, "You kid, you can calculate this, how can you calculate it?"

Wang Ke didn't hide it, and talked about the free fall again, it was gravity acceleration, time squared, and the relationship between the past life and the present, which made everyone dizzy.

"Okay, don't say it, I'm confused. Wei Tianxiang rubbed his head and said.

Wang Ke shook his head and said secretly: "Don't look at you are all great grandmasters, when you go to the earth, you can't even get into my technical school!"

Everyone lit torches and looked at them carefully.

The cave is wide underneath, two feet square, and because it is deep underground, it is not cold.

On one side of the cave, there is a horizontal hole, and the torch shines away, but there is still no end in sight, but the hole looks like it was built artificially.

"Wang Ke, let's calculate how long this hole is. Wei Tianxiang joked.

"Brother Wei, stop kidding. Hao Tianji said.

"Actually, you can try it too. Wang Ke said.

"Can you really figure it out?" Wei Tianxiang asked in surprise.

"Do your best. ”

Wang Ke said as he took out a fluorite from the treasure bag on his waist and bounced it into the cave.

He used his magic power with a flick of his fingers, which could eject the fluorite more than a hundred feet away, only to see a fluorescence flying through the hole, and finally hit the wall of the cave and turned into a piece of starlight.

After a breath, the sound of the fluorite smashing came, and Wang Ke smiled: "After a hundred and three zhang, if it is not the end, it is a turn." ”

"Okay, let's go see if it's as you said. Wei Tianxiang said with a smile.

Everyone walked towards the cave, secretly counting their steps to see if Wang Ke was accurate.

Sure enough, one hundred and three feet later, everyone came to a turn, just as Wang Ke said.

"Wang Ke, you're too godly, aren't you?" Wei Tianxiang exclaimed.

Wang Ke smiled: "Knowledge is power, and this is all knowledge." ”

"Tell me, how did you figure it out?" Wei Tianxiang asked, pestering Wang Ke.

"Listen to the sound, the speed of the sound is three hundred and forty meters per second......"

Wei Tianxiang hurriedly interrupted him and said, "I still haven't figured out how you got this rice?" Also, how do you know the speed of your voice?"

"Alas, Uncle Wei, this question is indeed more difficult for you, you should go and watch the sky at night. Wang Ke said with a smile on his face, making everyone laugh.

In the midst of laughter, I turned around along the cave and walked thousands of feet away before I finally saw a ray of light coming.

It's time to get there!

Everyone was overjoyed, and hurriedly quickened their pace, and when they walked to the light, they saw that there was another hole that was diagonally upward, leading to the surface and drawing in the sunlight outside.

At the end of the cave, there was the interior of an iceberg, several rooms had been carved out, and all the furniture was almost carved from ice, crystal clear, like a crystal palace.

"It's amazing, Brother word, what a lot of work, the people of the Yin and Yang family are too good at playing. Wang Ke couldn't help but say. (To be continued.) )
