"Take me the pi back and forth." The green-skinned frog cried.

"Uh," Fang Ning was stunned, and then immediately reacted, "No one can do this."

"Why?" the green-skinned frog was puzzled and then despised, "It's not that you can't do it yourself, you said that?"

"No, that's because Pi is an infinite number that never cycles. No one can finish it, let alone memorize it like a flow..." Fang Ning explained.

The green-skinned frog was stunned and then disbelieved: "If you say infinite, you will be infinite. You have to prove it to me. This question was given by that guy."

Fang Ning quickly ordered the guys in the Divine Prison to find the calculation formula for him. After all, except for remembering that the pi ratio was between 3.1415926 and 3.1415927, he forgot all the other related knowledge. He only remembered that the textbook did not give a specific derivation process.

Not long after, Fang Ning took out a stack of white paper from the system space and began to write down derivation formulas on it. It was not too long, but it was impossible for most people to make it out in just ten minutes unless professionals were professionals.

So outside the Tianmen, in full view of everyone, I saw Xia Ke Jia doing math problems in front of a frog, and math symbols fell on white paper one by one.

"My God, it turns out that the things that the way of heaven is to be investigated are so wide..."

"Yes, some people think that they can stop going to school and study after practicing. Now they should understand that as long as they have a shortcoming, some opportunities will pass by in the future."

Seeing this scene, many sarcasm disappeared immediately, replaced by various reflections.

"I didn't expect that the True Dragon, who is a Marquis who is 24 hours a day, actually has the ability to learn mathematics. It's really admirable."

"However, the math problems that Tiandao wants to solve should be very difficult, right? Can he solve them?" Some people still disbelief.

More than ten minutes passed, Fang Ning finally copied the answer and handed it to the frog to see.

"Damn it, that guy actually gave me a wrong question." The green-skinned frog jumped in place for a few times, and then said, "Okay, for your frog speech CET-6, even if you pass this time, you can continue to go up."

Upon hearing this, Fang Ning quickly sorted out the instrument, then moved forward steadily, easily climbing the third step, and before the fourth step.

"hiss!"

Outside the Tianmen, everyone was shocked to see this. Xiake Jia actually walked across the third step lightly?

This surprised them so much. They thought that the third step of this sudden change would either bring about a storm or a thrilling wave. I never expected that Xiakejia could pass the test by just solving a math problem?!

"Could it be that math problem is actually a difficult problem for the ages?" someone asked in confusion.

"It's not a difficult problem for all time. On the contrary, it's a mathematical problem that had a solution a thousand years ago, calculating pi." A monster with a very good look explained.

"Oh, Pi, what is the profound meaning of the Heavenly Way to examine this?"

"I don't know, maybe it's just a random problem, right?"

At this time, among the crowd watching the ceremony, a man in a robe looked down at the clouds under his feet, but he was thinking.

The way of heaven examines this must have a profound meaning.

It’s just that the Venerable passed so easily, but something was wrong.

Fang Ning did not raise his leg immediately before he reached the fourth step.

He asked the system master, "Can you get on? Do you have any new intuition?"

The system master hesitated and said, "I don't have any special feeling. It seems to be just an ordinary step, but is there any problem?"

Fang Ning looked around and found that the green-skinned frog was still under his feet.

He had a sudden inspiration and immediately sent a divine voice, of course, it was still a "quack" sound...

"Brother Frog, how do you want to walk on the remaining steps?"

"How to go? Just walk up directly, the test has ended. After the three steps of mind, strength, knowledge, the rest is to give you a reward for every step you walk." The green-skinned frog shouted.

System prompt: (The system hosts the host body.)

After Fang Ning retracted the system space, he could only say "hehe" to this prompt...

Outside the Tianmen, the people who knew nothing about this only saw the heroic abruptly stop, and some creatures began to speak loudly again.

"Haha, it seems that in the fourth level, Xiake A is about to be stumped again."

"Yes, this time, he definitely didn't pass that easily."

The southeast of Tianmen, the Demon Lord is in a difficult mind and his eyebrows are deeply locked. Of course, he could see clearly the calculation process of the third level just now, the Xiake A.

"Master, do you think Lord Qinglong's fourth level is very sad?" Yamanashi Saki asked worriedly.

Zhinan shook his head slightly: "There is no fourth level. For these nine steps, only the first three are the gates, and the back is rewarded."

"How did you know?" Yamanaki Saki was surprised and happy.

It is hard to laugh at but not to speak.

The middle-aged man in black robe said proudly: "The Buddha is very wise and knows all the words in the world. The Buddha already understands what the frog says."

"Hey, so, uncle in black robe, can you understand the frog's scream?" Yamanashi said in surprise.

"Uh... I was transformed from the Buddha's black robe. I have been with the Buddha for countless years. I also have this memory. I can understand the words of that frog." Hearing this, the black robe was a little embarrassed.

Sure enough, Xiake Jia walked up the fourth step.

Then a golden light flew out from the sky gate and fell on the body of the Xiake Arm.

Xiake Jia opened his right hand and saw a red fruit the size of a palm, with purple air rising on it, which was absolutely extraordinary.

Then everyone saw him smile slightly and then quickly walked up the fifth step.

Then another golden light flew out from the sky gate and landed in front of the Xiake Ar.

This time it was a hideous monster, with a terrifying shape that made people intimidate.

Everyone saw the eyes of the knight A lit up, and the white aura was soaring into the sky, pressing towards the ferocious monster.

The monster had no power to resist when facing the white air in the sky. It was swept over by the white air and immediately turned into nothing.

The sixth one is a piece of ore.

The seventh one is a sapling.

The eighth one, a cup of water.

The ninth one,...no more.

The system uncle wondered: "No, the reward given by Dad Tian should be getting better and better. Why doesn't this ninth one exist?"

Fang Ning was also puzzled and thought about it everywhere. Suddenly he saw the green-skinned frog that was still jumping with him, and suddenly said: "I know what the ninth one is?"

"What is it?" the system master asked in confusion.

"It's this frog." Fang Ning said affirmatively.

"Uh, is it turned into a certain princess? If you kiss a rich man, you will go back home with you? That's not possible. Don't forget that you can get married after level 100, and you are already engaged." The system master immediately said vigilantly.

"You just want to talk nonsense, how is this possible?" Fang Ning said speechlessly.

Then Xiake Jia lowered his head and asked Frog, "Brother Frog, what is the reward for this ninth step?"

The green-skinned frog said for granted: "Of course, I think you are the one who is the main one, and this is the biggest reward. You are the first person to pass the nine steps. I am the spirit of the Heavenly Monument. Before you had a mysterious guy on you, and you beat me for a long time, and I could only succumb to it temporarily. Now that you have passed the test, I sincerely surrender to you. In the future, I will teach you all the secret uses of this Heavenly Monument."

"Uh, so that's it." The system master was very depressed.

It said to Fang Ning: "There is no reward for the ninth level. This frog is originally the spirit of the Heavenly Monument. I will beat it a few more times. There is no need for it to really surrender."

Fang Ning said speechlessly: "Forget it, I said that the sky monument always felt useless before. It turned out that it had many things that didn't tell us. It turned out that it was a forced melon that was not sweet. Fortunately, it is devoted to it now, and it will probably be very powerful in the future."
