The time for the ping pong ball to bounce back when it hits the stone wall is extremely short and extremely fast.

But under Cheng Mo's keen perception, all this seems to have passed the time to unravel a higher mathematical function.

Cheng Mo meditated for a long time and said: "The thickness of the stone wall is about 1.2 feet, and there is indeed a mystery behind the stone wall. ”

After the collision of the table tennis ball just now, Cheng Mo has estimated the thickness of the stone wall, which is the five-step table tennis stone wall invented after his cultivation has been continuously improved and his perception has become stronger and stronger.

Before, he tapped the stone wall with his fingers, but on the stone wall in front of him, the electric snake swam away, and if he was not careful, he might be electrocuted.

This five-step table tennis stone wall can avoid the human body from directly contacting the stone wall with points, avoid being shocked, and indirectly measure the thickness of the stone wall.

In addition, coupled with the frequent study of Uncle Scar's codex, Cheng Mo has a certain understanding of the mechanism of this stone wall.

Cheng Mo is secretly happy, a large part of Uncle Scar's codex is about the things in the ancient tomb, as well as the way to find and crack the mechanism.

Feng Boping saw Cheng Mo throwing a ping-pong ball and knew the thickness of the stone wall, as well as the mystery inside, and said contemptuously: "Cheng Mo, you brag, you can know so many things with a table tennis ball, you are playing tricks." ”

Before Cheng Mo replied to him, Qiangzi replied first, "Hehe, the storm is calm, you know that you are spoiled by your parents and elders all day long, and you don't know the life of the common people, Cheng Mo followed his father to hit stones, and he knows everything about stones since he was a child, as long as he gently knocks on the stone with his fingers, he knows the thickness of the stone, this, a good baby like you can't learn." ”

As soon as Feng Boping was said by Qiangzi, his hair stood up angrily.

"You, you."

Cheng Mo looked at him and smiled disdainfully, "How about it, Feng Boping, you have to bet again, if I can really open the stone wall and prove that there is still space behind this stone wall, what are you willing to lose to me?" ”

When I heard the turmoil, I couldn't remember what to say for a while.

Feng Thunder's face twitched, their Feng family had always acted cautiously.

But Feng Boping's impetuousness and frivolity twice in one day are really far from their Feng family style.

Feng Boping didn't want to let Cheng Mo gain the upper hand, and said: "If what you say is false, it is a great disrespect to our Feng family. ”

Cheng Mo saw that several elders of the Feng family ignored him and walked towards the stone wall, leaving Feng Boping standing there awkwardly.

Fengyu whispered: "Father, it's because I let Ping'er get used to it, so he will speak like this." ”

Feng Thunder sighed secretly, "No, it's not all your fault, Ping'er has been too good since she was a child, so let's ignore other aspects of discipline." ”

A mechanism was found in another stone wall of Chengmo, and a stone block was pulled out, revealing a small square hole, but there seemed to be a mechanism in the square hole.

"Everybody stand back."

Qiangzi and Liqiu both took a few steps back when they heard Cheng Mo say this.

The people of the Feng family retreated even farther away, this organ, they really don't know, if they are injured by their own organs, and it is spread to the realm, it will be strange if everyone laughs off their big teeth.

Seeing that everyone had retreated, Cheng Mo followed the record of the bearded codex, his fingers were as hard as steel nails, and his speed was as fast as the wind.

Cheng Mo stretched out his thumb, index finger, and middle finger, and his hand was as fast as electricity.

I only heard the sound of ping-pong coming from inside the mechanism.

Feng Boping said secretly: "Damn, will this guy be demolishing the ancient tomb, if so, grandpa doesn't speak, this hatred, I also wrote it down with you." ”

In the square hole, several sharp steel needles were inserted from all sides in a disorderly manner, and some flew directly out of the hole and flew out towards Chengmo.

But all this happened after Cheng Mo quickly unlocked the mechanism.

Cheng Mo quickly dodged the steel needle, and his body was unscathed.

I only heard a rumbling sound, and the stone wall opened like a stone door, and a cold feeling quickly came out.

"It's strange, it's windy in this burial chamber," Wind Thunder said secretly in his heart.

This wind gave him a new understanding of the graves of his ancestors.

Childhood memories, this place of refuge, is a safe haven.

But now, this is the ancient tomb that made him, a Taoist second-grade realm of the onmyoji, feel trembling.

After the stone wall was fully opened, a spacious burial chamber appeared in front of everyone.

All this is like opening the door to block time and space, inside is a hundred years ago, outside the door is modern, and two strange breaths are colliding.

The wind and thunder were so frightened that he knelt on the ground, "The unfilial descendants are thunderous, and they have no intention of disturbing the ancestors' spirits, and they also ask the ancestors to atone for their sins." ”

The wind and rain and the wind also knelt on the ground, and followed his father's wind and thunder and kept knocking his head.

Cheng Mo could hear the sound of them kowtowing from afar.

"Bang, bang."

Cheng Mo sneered secretly in his heart, "Heh, the descendants of the Feng family kowtow quite hard." ”

Feng Boping looked at the tomb and was stunned, and it took a long time to react, and he learned from his father to kneel down quickly and kowtow to atone for his sins.

Cheng Mo looked into the tomb, and the tomb was empty.

There weren't many decent ornaments inside, and it seems that the owner of the tomb didn't hide many treasures in those war-torn years.

There is a coffin in the middle of the burial chamber, which is very well sealed and looks intact.

Cheng Mo folded his hands eleven times and quickly threw a burst of paper talismans towards the tomb.

When the paper talisman floated into the tomb, it touched the formation, and immediately showed a dim light shape.

Cheng Mo tried to step into the tomb, and where the light was, an electric snake was quickly generated and attacked towards Cheng Mo.

Cheng Mo quickly took out another paper talisman and blocked the electric snake.

This is still on the edge, if it is the same as the day of Liqiu, enter the center of the formation, not to mention the waste of paper talismans, he does not have the skills of Liqiu, he can only be trapped by the formation, and there is no hope of escape.

Cheng Mo Tomb stared at the position of the coffin, "Liqiu, I continue to stimulate the formation, you take the portrait of the wind curtain de, avoid the light to the position of the coffin, and when the formation changes rapidly and attacks you, you quickly unfold the portrait in front of you." ”

Liqiu took the portrait and nodded slightly.

Cheng Mo was a little worried, but the only one who could avoid the criss-crossing light was Liqiu.

This time, it must be dangerous.

The last time, they were above the tomb, they all got out in a thrilling way.

This time I was directly in the tomb, and I didn't know what would happen unpredictably.

Cheng Mo turned to the Feng family who was still kowtowing and said, "Senior Feng, we will communicate with your Feng family ancestors, but the descendants of your Feng family will come out to make trouble, and if something happens, you will bear it yourself." ”

"You should know best how high your cultivation is before Mr. Zu."
