"Fellow Daoist Hou, it's your turn."

"Uh..." Hou Dongsheng entered the stone house with a worried look on his face.

Seeing Hou Dongsheng's appearance, the little Taoist boy showed unabashed sarcasm.

"Hmph! It's too late for you to regret it now. The strange math problem that the real person came up with is so difficult that even the real person himself finds it extremely difficult. How can it be so easy for opportunistic people like you to solve it?"

The two of them entered the stone house together.

There is a piece of cloth hung on the wall of the stone house. There is a circle on the cloth with a straight line in the middle.

The diameter of Xiaodao Tongzi said: "The diameter of this circle is 1. Please, fellow Taoist, calculate the circumference of this circle."

"Oh..." Hou Dongsheng smiled.

How to say this question?

The difficulty is definitely there.

After all, this is the category of irrational numbers, which is much more difficult than the chicken and rabbit problem.

But if Hou Dongsheng is asked to calculate pi on the spot, he definitely doesn't have the ability.

Fortunately, he remembered the calculation results.

Hou Dongsheng said with a smile: "The circumference of this circle is 3.1415926..."

A smile appeared on the little Taoist boy's face, his eyes widened and his face was full of shock.

Empty island.

The inner court.

In a quiet little courtyard.

Densely covered with pebbles and shallow water.

Two monks in white were sitting on a wooden couch, which was placed directly on the cobblestones and shallow water.

The two people sitting on the wooden couch look like young men and women in their twenties. The man is handsome and handsome, and the woman is dignified and beautiful.

Two people sit opposite each other, one holding a white chess piece and the other holding a black chess piece, slowly making moves.

These two people are Master Kukai and Master Lin Huaibing respectively.

Half an hour later...

Lin Huaibing sighed, surrendered and said: "Sir, your chess skills are indeed extraordinary, Huaibing is no match for you."

"Fellow Daoist Lin has come all the way to play chess with me, right?" Master Kukai asked with a smile on his face.

"Sure enough, I can't hide it from you, sir. Please identify the origin of this object." Master Lin Huaibing took out a magic weapon from his storage bag and handed it to Master Kukai respectfully.

Master Kukai just took one look at it and said, "This is a ghost magic weapon."

Lin Huaibing looked shocked: "So the only ones who can use this thing are ghost cultivators?"

Master Kukai: "It can also be used by living monks, but it requires special techniques."

Lin Huaibing: "I am afraid that the only three major demon sects in the world that can control this thing are Lianyou Sect, Blood Corpse Sect, and Youquan Sword Sect."

Master Kukai: "The refining technique of this object is similar to that of the Refining You Sect."

Lin Huaibing, a cultivator, has only heard of the Lianyou Sect so far. As an offshore monk in the Chixia Sea, all the sects on the land are too unfamiliar to her.

Lin Huaibing: "The Lianyou Sect is a demon giant at the same level as the Demon Flame Sect. Why would they kill our Lin family members?"

"Everything has a cause and effect." Master Kukai said in a Zen-like way.

Lin Huaibing showed a hint of embarrassment.

Because Lin Qingyou became greedy for Tianhai Clam Pearl, but due to his lack of strength, he kicked the iron plate and was killed.

Lin Huaibing: "To tell you the truth, sir, it's because he is a greedy monk from the Ghost Path and Demon Sect. He killed people to seize treasures and harmed my Lin family members."

Master Haikong smiled slightly but did not point it out.

Lin Huaibing: "In addition to letting real people identify this thing, Huaibing also has another thing to do during his trip."

"But there's no harm in talking."

"I wonder if Kukai Master knows anything about the labyrinth array."

"Lin Qingyou once wrote to me asking me about the labyrinth formation. Didn't he tell you?"

Hearing this, Lin Huaibing looked stunned.

"I understand... the one who was killed by the ghost monk was Lin Qingyou."

Lin Huaibing: "You really can't hide anything from the real person. The murdered member of my Lin family is indeed Lin Qingyou."

"Aside from this ghost magic weapon, what other clues are there?" Master Kukai asked.

"In addition to this magical weapon, there are indeed three other clues. One is a casual cultivator named Hou Dongsheng. This person has a very obvious characteristic of carrying a big gourd. It was this person who led Lin Qingyou to the sea outside the island.

He killed him, so even if Hou Dongsheng is not the direct murderer, he must have a close relationship with the ghost demon sect; secondly, according to the survivors, the ghost demon sect monk is a female cultivator, dressed in red, using black and red.

The third is that there was a violent explosion on the outer sea that day. The flames burned on the sea and did not go out for a long time. Its power was not inferior to the full blow of the Demon Flame Sect Jindan real person." Lin Huaibing simply investigated himself.

Tell everything you know.

After Master Kukai listened, he pondered for a moment and then said: "I have never heard of Hou Dongsheng. Also, don't ask me about the labyrinth array. I have never seen this array and know nothing about it.

"

"We, the Lin family, can take Master Kukai to the Banshee Secret Realm. I believe that with your talent, you will be able to easily get through the maze. As long as you can get through the maze, you can get a share of the treasure first." Lin Huaibing stood up and said with clenched fists.

"Hehehehe... The two Taoist friends Wang Baoyu and Xue Honglei offered much higher conditions than Taoist friend Lin."

Lin Huaibing: "The Wang family and the Xue family also came to see Mr. Xiang?"

"Don't worry... I have no interest in the Banshee Secret Realm. I have not agreed to any of your family. No matter what conditions you set, I will not go to the Banshee Secret Realm." Master Haikong said with a gentle face.

Lin Huaibing: "It's really admirable that a real person has noble conduct."

"Being noble? Haha... It has nothing to do with this. Everything in the world has cause and effect. Why don't you think more about it, Fellow Daoist Lin."

"What are you thinking about?"

"Why does that banshee secret realm exist? It can't be a place specially designed to give treasures to you three families."

"Forehead……"

Master Kukai: "Fellow Daoist Lin...it's getting late, please go back."

Master Kukai issued an order to expel guests in person, so Lin Huaibing naturally did not dare to say anything more. She bowed with her fists together, bowed deeply and then left.

After Lin Huaibing left, Master Kukai picked up the chess pieces on the chessboard one by one, moving slowly and carefully.

He could have used Taoism to collect all the chess pieces in an instant, but he chose to use his hands to pick up the chess pieces one by one like a mortal.

The word patience is interpreted to the extreme.

When Kukai master collected all the chess pieces.

He sat cross-legged with a calm expression, as if listening to the dew and watching the clouds rolling and relaxing in the sky.

After a long time.

Master Kukai: "Come in."

I saw a small group of children outside the door stepping in, clasping their fists and bowing to Master Kukai: "A casual cultivator named Hou Dongsheng has solved the circumference of a circle."

"Oh...how many people can this person count?"

"I calculated the eight digits. The first six are correct. The last two real people didn't give the answers, so I don't know."

"How many can he count?"

"He said he could only calculate to 8 digits."

"Calculating the circumference of a circle becomes more difficult with each additional digit. It is already rare to be able to calculate 8 digits."

"By the way...is this person really called Hou Dongsheng? Does he have a big wine gourd on his back?"

Little Taoist: "That's not true...but he asked a real person to refine the weapon. It seems that he wants to refine a big wine gourd into something big or small."

"Isn't it simple whether it's big or small?"

Little Taoist: "He asked that the gourd be filled with living things."

"Oh...this is somewhat interesting."

"Does the real person want to see this person?"

"If you don't have faith, you won't stand. Since this person can solve the odd calculation of a circle, I naturally want to meet him."

Little Taoist: "Then I'll go and invite him in."

"Wait a minute!"

Kukai Zhongzhen thought for a moment.

"Take him to Shawan and ask him to wait for me at the stone platform in Shawan."
