"If you call it it won't tell you the answer, hahaha!"

Seeing that the Song people were actually shouting at the opposite cliff, Miyamoto's father and son, as well as those retainers, all laughed heartily, and even Qin Hui and Ning Yuan were full of embarrassment.

"Xiao Li, you should find a way to measure it!"

This little scholar was discharged by Wu Zhi, and although Qin Hui and Ning Yuan were a little embarrassed, they were still very confident in this little scholar.

And the little scholar just turned his head to Qin Hui Ning Yuan slightly, and began to pinch his fingers and calculate the matter.

"Ah~"

…… The scholar shouted again at the cliff ahead.

"Hahaha......"

"Master Wu, could it be that you, a student, are crazy, why do you keep shouting at the cliff?"

"That's a bit out of place!"

The Japanese continued to laugh, but Wu Zhi smiled very calmly and did not speak, Qin Hui and the others around him saw that Wu Zhi was confident, so they no longer talked much, and could only be cheeky and let the Japanese laugh.

Even Suzuki-kun was very embarrassed, so he simply shrank at the end and didn't show up.

"Ah~"

The little Li scholar pinched his fingers and shouted at the cliff for the third time.

"Master Wu, if it really can't be measured, we won't be reluctant to ........."

"Yes, did you let us spend half of our time here listening to this junior yelling?"

Miyamoto Nobo and Miyamoto Lang, father and son, began to urge Take-sik.

"What are you anxious about? A pillar of incense has just burned at the beginning, and we adults have our own way! ”

Han Shizhong, who had been in the rear guard team, heard that the Japanese seemed to be a little disrespectful to Wu Zhi, so he stepped forward and looked at the Japanese coldly.

It was Gong Ben Lang, although he was much shorter than Han Shizhong, but when Han Shizhong stepped forward, he also touched the saber on his waist for the first time, and his face was full of disbeze.

"Xiao Han, don't be rude."

Wu Zhi raised his hand slightly and asked Han Shizhong to step back, and then he looked around at everyone in the Miyamoto family and couldn't help but smile.

"Don't worry, everyone! The distance between these two cliffs, I think my student has figured it out! ”

After speaking, Wu Zhi turned his head to look at Li Shusheng, Li Shusheng withdrew his calculating hand and nodded respectfully at Wu Zhi.

"It's been calculated."

"Figured it out?"

Miyamoto Yewang and the others looked at each other, but at tea time, they didn't know how the Song people started, and they had already calculated it?

"Could it be...... Could it be that shouting those three voices is measuring the distance? ”

Lord Qin Huining also looked incredulous.

"Yes, Xiao Sheng shouted those three times just now to measure the distance between the cliffs." Li Shusheng replied.

Qin Hui and the Miyamoto family and the others were immediately dumbfounded.

"Ridiculous! Nonsense! Just shouted three times, how can you measure the distance between the cliffs?! ”

Miyamoto Lang sneered, and Miyamoto Yewang also brushed his sleeves at Li Shusheng and said, "Tell me, how many feet is the distance between these cliffs!" ”

The Song people measured the ancient tower, at least measured it, and used the arithmetic they didn't understand to calculate the height of the tower, although it was not simple, but it was always reasonable.

But now, just shouting a few voices to say that the distance between the cliffs has been measured is a baseless fantasy in the eyes of the Japanese!

"Returning to the Venerable Master, returning to everyone."

Li Shusheng looked at the Japanese calmly: "After the average value of the next three measurements, the distance between these two cliffs is about 16 zhang 8 feet 5 inches, and the error should not exceed one inch. ”

As soon as these words came out, Lord Qin Huining and the others on Wu Zhi's side were confused, but Miyamoto Yewang was already pale and sweating profusely.

"Impossible! It can't be so accurate! ”

"So, I'm the right student, isn't it, Miyamoto-sama?"

Wu Zhi slowly unfolded the folding fan and looked at the people of the Miyamoto family leisurely, although these little Japan are all kinds of small families, they are still quite honest.

"It can't be! You must be cheating! You ......"

Miyamoto suddenly jumped up in anger, but was held down by the sick Miyamoto Taro, and Miyamoto Yewang on the side also glared at him.

"Bastard! Don't be rude to Master Wu! ”

Miyamoto is not a brainless person who hopes to be a prince in Japan, he understands that this place was chosen by him temporarily, and the problem is also improvised, and there will be no leaks at all.

The Song envoys had only been in Nagasaki for a few days, and it was impossible to know the distance of the coastal cliffs in advance.

"Master Wu has ingenuity and wisdom, and his subordinates are full of talents, so I admire them!"

Li Shusheng's answer was not bad at all, and in this second game, Miyamoto had no choice but to admit defeat to Wu Zhi.

"But this is too magical, could you please reveal how your students were able to calculate the distance between the cliffs with just a few shouts?"

Looking at the bewildered expressions of Miyamoto Yewang and the people behind him, Wu Zhi smiled faintly.

"Miyamoto-kun, let me ask you a question?"

"What's the problem?"

The Japanese continued to be confused.

"Why do you see lightning and then hear thunder when there is thunder?"

"This... This ........."

Miyamoto Yewang's face was full of confusion, he was over half a hundred years old, so naturally he couldn't answer Wu Zhi's "because the eyes grow in front of the ears", but why, he didn't know at all!

"Hahaha........."

Wu Zhi looked up to the sky and laughed, then strode off the coast and walked towards the carriage on the road.

"This question is very simple, if you want to know, just send some international students to Qingzhou University for further study, but the tuition will not be cheap!"

Solved a problem for the Japanese unpredictably, Wu Zhi was arrogant, and the guards and students of the Great Song Dynasty officials who followed him were full of pride, and the eyes of Lord Qin Huining and other civil officials looking at Wu Zhi were full of admiration.

Idol......

"Master Wu is broad-minded, I admire it!"

Miyamoto Yewang led a group of people to catch up with Takeshi, and patted him again and again, after all, Takeshi agreed to teach these "secrets" of measuring distance to the Japanese so easily, which is indeed great in their eyes.

And the "secret" algorithm in the eyes of the Japanese really does not belong to this era, because no matter how smart the ancients were, it was impossible to calculate the speed of sound transmission.

And the propagation speed of sound is 340m per second, which is the most basic knowledge of junior high school students in later generations, Wu Zhi naturally remembered it, and then when he wrote the textbook for Qingzhou College, he wrote it.

Knowing the speed of sound propagation, you can easily calculate the distance between the two cliffs by simply shouting at the cliff on the other side and measuring the time of the echo.

The wind and waves are calm here, and Li Shusheng measured the average three times, and the data is naturally accurate.

Therefore, knowledge is power, and the reason why Wu Zhi is so high-spirited now is actually to bluff these little Japan with the knowledge that junior high school students will have in later generations.

"Miyamoto-sama, there is one last question, I don't know what problems you will give us in this last question?"

Before getting into the carriage, Wu Zhi asked Miyamoto Yewang confidently.

As long as the last problem is solved, the gold mine will be in hand, and when the time comes, the Great Song Dynasty will occupy the reason, and Japan will not regret it, and if you dare to regret it, you will directly send the Qingzhou Navy to destroy the Miyamoto family!

A few thousand soldiers and horses can be called princes in Japan, but in the Great Song Dynasty, he is actually a county magistrate!

"Lord Wu, please get into the carriage."

After Miyamoto Nozomi respectfully invited Takeshi into the carriage and drove away, his two sons and retainers also surrounded him with solemn faces.

"Father, I can't let the Song people succeed anymore!"

"Yes, my lord, please come up with a question that they will never be able to do!"

Miyamoto and the retainers were very anxious, but the sick Taro Miyamoto kept his composure.

"Father, we are not as good as the Song people in terms of wisdom, so I suggest that the last question should be to attack their weaknesses!"

"Weaknesses?"

Miyamoto looked at Taro Miyamoto curiously.

"Not bad! Their weakness is ........."

Taro Miyamoto approached Miyamoto Nobo's ear and muttered a few words, and Miyamoto Nobomi was immediately overjoyed.

"Haha! Good! This time the Song people are doomed! ”

Not far away, Suzuki Nobunaga, who tried to eavesdrop but didn't hear, was a little worried, although he was Japanese, he very much hoped that the Song people would take the gold mine.

Because he knew that the Song people would never treat the Japanese badly after taking the gold mine, and he himself wanted to act as an agent for the Great Song Bank in Japan, and then all the princes of Japan would have to look at his face!
