"Cultivation is boring, it's too boring." Ren smiled.

"Then you go and talk to the second elders, or Xiong Daxiong Er."

"The age difference between the two elders is too big. The thunder beast race is different. There is no common topic. We are the right age." Ren said with a wink.

chat?

I'm very busy, have time to chat with you?

Qin Cheng rolled his eyes straight.

"Brother Cheng, please find a topic, chat with me, or have some fun. Now you can't use your spiritual energy, I'm almost suffocating." Renn asked for help.

Qin Cheng's eyes fluttered, his heart moved.

"Brother Lei, are you just too bored to stay and want to find something to do or have a goal?"

"Yes, that's it." Renn nodded.

"Then this way, I will give you a question. This question is quite difficult, I'm afraid you can't do it." Qin Cheng smiled with some bad taste when he thought of a certain idea.

Since this guy is so idle, just give him a tired question, so as to save yourself trouble.

"Don't you think of me? There is anything I can't do, just come."

Rennes couldn't stand the excitement and instantly aroused his fighting spirit.

"The question is this, it's very simple. Have you played chess, suppose there are 1,280 grids in this chessboard, the first grid has a spirit stone, the second grid has two, the third grid has four, the fourth grid has eight, and the fifth grid has a fifth one?"

"Sixteen spirit stones, do you think I'm stupid?" Ren said disdainfully.

"Is this also called a question?"

"Smart, then, next, even if you calculate, how many spiritual stones are needed to fill the board in this way."

"Science is it right? Fellow Daoist Cheng, you underestimate me too much. For such a simple question, you can wait and give you the answer after a stick of incense." Ren said confidently.

"Really, so confident? What if you can't answer?" Qin Cheng said.

"I can't answer it, I will never bother you again." Renn swore.

"Okay, please do it, I'll wait for news of your victory."

Qin Cheng smiled.

This question was originally about putting rice on sixty-four grids, which was already a worry that all the wise men of Blue Star at that time, and few could answer it.

And Jiuzhou Lu does not have such a sophisticated math formula. I have increased the difficulty of you twenty times. Can you answer it with an incense stick?

Can you answer my last name!

Next, Qin Cheng closed his eyes with peace of mind and began to immerse himself in the cultivation.

Renn looked confident, his spiritual sense was running rapidly, and he began to calculate.

"Sixteen, the next one is thirty-two, and then sixty-four..."

At first, Renn's face was full of smiles, but as he calculated, his head began to dizzy.

Why did this number suddenly become so big?

It was obviously very simple at the beginning, but it was only a dozen grids, so the number was a big breakthrough he imagined.

Next, Renn began to become serious and take Qincheng's problems seriously.

Half an hour later, the confidence in Renne's eyes began to dissipate and his expression became dull.

What's the problem of trampling on this horse?

I have realized that if I want to do this, it will be extremely difficult!

How did Qin Cheng, this pervert, think of such a tormenting problem?

Renn felt as if he had been cheated. He looked at Qin Cheng and was a little weak. He opened his mouth, but quickly closed it.

No, you can't give up. This is what I promised. If I admit defeat, where will I put my face?

Three hours later, Renn seemed to be crazy, his lips kept buzzing, and his eyes were filled with blood.

At this time, Qin Cheng's spiritual sense had already entered the refining space and sat cross-legged on the ground comfortably.

In front of me, what was suspended was the slightly open Heavenly Book. Not far away, there were more than a dozen moon pearls emitting light.

Before, Qin Cheng had not sent the wordless heavenly book into the refining space.
