"Recite pi by heart." The green-skinned frog croaked.
"Uh," Fang Ning was stunned for a moment, then immediately realized, "No one can do this."
"Why?" The green-skinned frog was confused, and then said scornfully, "You can't say that because you can't do it yourself, right?"
"No, that's because pi is an infinite non-cyclic number. No one can memorize it, let alone memorize it backwards and forwards..." Fang Ning explained.
The green-skinned frog was stunned for a moment, and then he didn't believe it: "You said it's infinite, so you have to prove it to me. This guy gave this question."
Fang Ning quickly asked the guys in the prison to find out the calculation formula for him. After all, except for remembering that the pi ratio was between 3.1415926 and 3.1415927, he had forgotten all other related knowledge. He only remembered that the textbook did not give specific information. The derivation process.
Not long after, Fang Ning took out a stack of white paper from the system space and began to write out the derivation formulas one by one on it. It was not too long, but unless it was a professional, most people would want to figure it out in just ten minutes. , are all impossible.
So outside the Tianmen, under the watchful eyes of everyone, they saw Knight A doing math problems in front of a frog, and mathematical symbols fell on the white paper one by one.
"Oh my God, it turns out that the things that Heavenly Way wants to examine are so vast..."
"Yes, some people think that they can stop going to school or study after practicing cultivation. Now they should understand that as long as there is a shortcoming, some opportunities will pass by in the future."
Seeing this scene, many sarcastic voices suddenly disappeared and were replaced by various reflections.
"I didn't expect that the real dragon who travels 24 hours a day would actually have time to study mathematics. It's really admirable."
"However, the math problems that Tiandao will ask should be very difficult, right? Can he solve them?" Some people still don't believe it.
More than ten minutes passed, and Fang Ning finally finished copying 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 on the spot a few times, and then said: "Okay, for the sake of your level 6 frog language, even if you pass this time, You can keep going up."
Hearing this, Fang Ning quickly adjusted her appearance, then moved forward steadily, easily ascending the third step and arriving at the fourth step.
"hiss!"
Outside the Tianmen, everyone was shocked when they saw this. Knight A actually walked through the third step so lightly
This was too surprising to them. They thought that this sudden third step would either bring a stormy sea or be thrilling. They never expected that Knight A could pass the level just by solving a math problem? !
"Could it be that that math problem is actually an eternal problem?" someone asked doubtfully.
"It's not an eternal problem at all. On the contrary, it's a mathematical problem that had a solution thousands of years ago. Calculating pi." A monster with excellent eyes explained.
"Oh, pi, what is the meaning of this investigation by Heaven?"
"I don't know, maybe it's just a random question?"
At this moment, among the people watching the ceremony, there was a man in robes. Seeing this, he lowered his head and looked at the clouds under his feet, but he was thoughtful.
There must be profound meaning in Tiandao's investigation of this.
It's just that it's not right for the Venerable to pass the test so easily.
Fang Ning did not lift her legs immediately before reaching the fourth step.
He asked the system man: "Can you go up? Do you have any new intuition?"
The system uncle hesitated: "I don't feel anything special. It seems to be just an ordinary step, but is there something wrong with it?"
Fang Ning looked around and found that the green-skinned frog was still under his feet.
He had an idea and immediately sent a message with his spiritual mind, and of course it was still a "croak"...
"Brother Frog, may I ask how to walk the remaining steps?"
"How to go? You just go up. The test is over. Willingness, strength, knowledge. After three steps, the only thing left is to give a reward for each step you take." The green-skinned frog yelled "Quack" .
System prompt: (The system is hosting the host body.)
After Fang Ning retracted the system space, she could only say "haha" to this prompt...
Outside the Tianmen, everyone who knew nothing about it only saw Knight A stop, and some creatures began to speak nonsense again.
"Haha, it seems that in the fourth level, Knight A will be stumped again."
"Yes, this time, he will definitely not pass so easily."
In the southeast of Tianmen, the Demon Lord was in a difficult situation and his brows were furrowed. Of course he could clearly see the question of the third level and the calculation process of Knight A.
"Master, do you think Master Qinglong's fourth level is difficult?" Saki Yamanashi asked worriedly.
Zhi Nan shook his head slightly: "There is no fourth level. Of these nine steps, only the first three are levels, and the rest are rewards."
"How did you know?" Yamanashi Saki was surprised and happy.
It is difficult to laugh without speaking.
The middle-aged man in black robe said proudly: "Buddha has great wisdom and understands all the languages in the world. Buddha has already understood what the frog said."
"Hey, so, uncle in black robe, you can also understand the cry of frogs?" Yamanashi asked in surprise.
"Uh... I am the incarnation of the Buddha's black robe. I have been with the Buddha for countless years. I also have this memory. I can also understand what the frog said." The black robe was slightly embarrassed when he heard this.
Sure enough, Knight A walked up the fourth step.
Then a golden light flew out from the Tianmen and fell on Knight A.
Knight A opened his right hand and saw a palm-sized red fruit with purple energy rising from it. It was absolutely extraordinary.
Then everyone saw him smile slightly and quickly walk up the fifth step.
Then another golden light flew out from the Tianmen and fell in front of Knight A.
This time it was a ferocious monster, its form was so terrifying that it was intimidating.
Everyone saw Knight A's eyes light up, white energy rising all over his body, and he pressed towards the ferocious monster.
The monster was unable to resist in the face of the white air. It was swept away by the white air and turned into nothing.
Sixth, a piece of ore.
The seventh one is a sapling.
Eighth, a glass of water.
The ninth one... is gone.
The system uncle wondered: "That's not right. The rewards given by Father Tiandao should be getting better and better. Why doesn't this ninth one exist?"
Fang Ning was also puzzled and looked around. 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 uncle asked doubtfully.
"It's this frog." Fang Ning confirmed.
"Uh, could it be that it was transformed into a princess? Will a rich man turn back and follow you home if you kiss him? That's not possible. Don't forget that you can only get married after level 100, and you are already engaged." The system. The uncle immediately said vigilantly.
"You are just telling me nonsense, how is this possible?" Fang Ning said very speechlessly.
Then Knight A lowered his head and asked the frog: "Brother Frog, what is the reward for this ninth step?"
The green-skinned frog said matter-of-factly: "Of course I recognize you as my master. This is the biggest reward. You are the first person to pass the nine steps. I am the Heavenly Monument Artifact Spirit. There was a mysterious guy on you before, who beat me For a long time, I could only temporarily succumb to it. Now that you have passed the test, I sincerely surrender to you. From now on, I will teach you all the secret uses of this heavenly monument."
"Uh, that's it." The system uncle was very depressed.
It said to Fang Ning: "As expected, there is no reward for co-writing the ninth level. This frog is originally the Heavenly Monument Artifact Spirit. I can just beat it a few more times. There is no need for it to surrender sincerely."
Fang Ning was very speechless and said: "Forget it, I just said that this heavenly monument always felt useless before. It turns out that it didn't tell us many things. As expected, the melon is not sweet, but fortunately it If you devote yourself wholeheartedly now, you will surely be very powerful in the future.”
When the system uncle heard this, he was slightly satisfied: "That's okay, it depends on its performance in the future. If it doesn't perform well, I will beat it a few more times."
