"So powerful!"

    Everyone looked at Merton in amazement, as if he were a monster.

    "I want to learn! I want to learn lightning mental arithmetic!" little Zhengtai Li Zhi''s eyes are shining. He calculates so quickly. It''s not easy for him to do his homework in the future. How much time can he save to play!

    "Don''t worry, your highness. Lightning mental arithmetic needs a lot of practice and a solid foundation of arithmetic. I can''t succeed until I practice hard for three years." Merton''s words mercilessly exposed Li Zhi''s dream.

    "Three years of success?" many princes suddenly extinguished their mind of learning, and Li Shimin was also slightly disappointed. Unlike others, the princes need to learn too many things. Such calculation can be calculated slowly with ordinary methods, and there is no need to spend a lot of time on it.

    "Hey!"

    Li Zhi was immediately disappointed, and his little face suddenly drooped. He was the youngest and had the worst foundation in mathematics. He was blocked if he wanted to take a shortcut.

    Merton looked at Li Zhi''s disappointed expression, but he couldn''t bear it. Suddenly he saw the calculation chip in Wei Zheng''s hand and said, "but compared with lightning calculation, there are some relatively simple calculation, such as abacus calculation with the help of calculation chip and the simplest calculation."

    "Mental abacus, finger counting!" Li Shimin frowned and looked at Merton.

    He can understand the abacus mental arithmetic, but what''s the matter? Does he still want to train all the front princes into divine sticks? Although they think they are the descendants of Lao Tzu, they don''t intend to be divine sticks.

    When a prince did his homework, he pinched his fingers and counted. Who knows whether it was really calculated or guessed.

    Merton hurriedly explained: "elementary school children will count with their fingers when they are initially exposed to arithmetic. Finger counting is to increase the accuracy and speed of counting on the basis of finger counting. It is most suitable for elementary school children."

    Merton simply demonstrated the method of finger counting. After Li Zhi tried it, he easily worked out some problems he thought were very difficult, and immediately smiled. This method is very suitable for him. Usually some problems can be solved soon.

    As for Li Ke and other princes, they chose abacus mental arithmetic. Unexpectedly, Li Chengqian and Li Tai chose the most difficult lightning mental arithmetic.

    At this time, Merton finally saw the signs of the two. Considering the rumors of the two in future generations, he wisely shut up.

    Everyone got what they wanted. As soon as Li Shimin waved, all the princes immediately looked like birds and animals, of which Li Zhi ran the fastest.

    Merton also wants to go, but Li Shimin hasn''t spoken yet. Obviously, he doesn''t want to let him go. When Li Chengqian left, he gave him an expression of helplessness and left without loyalty.

    "You can toss things around! Even if you visit a brothel, you can make a scene all over the city! Now the whole Chang''an city is spreading your name of Merton." Li Shimin has no expression, but Merton really has a sudden heart. He doesn''t say that he won''t settle accounts. Why did he suddenly change his mind? Do people have integrity.

    "The decathlon Mexican family. I''ve heard of it!"

    The old man Wei Zheng is unkind. He even came to mend the knife at this time.

    "Decathlon?" Merton could not help frowning. Who gave him the title? Didn''t he win him?

    "Well... In fact, the boy still has many shortcomings!" Merton said a few words and then said.

    "Hum! You still know humility!" Li Shimin snorted coldly and looked at Merton for a moment of helplessness! The boy is capable and talented, but he just keeps going and can make big things wherever he goes.

    "The Mohist school has been silent for thousands of years, and you have been cultivated as a tired slacker!" Li Shimin said angrily.

    "If you return to your majesty, the Mohist school has been silent for thousands of years, but you have devoted yourself to learning, and what the boy has learned is just a fur." Merton said positively.

    Li Shimin nodded and said unintentionally, "it''s said that this figure comes from Tianzhu. So the Mohist sages have also been to Tianzhu, and an eminent monk in our Dynasty once went to Tianzhu to ask for the Scriptures! According to the news from the border, the eminent monk Xuan Zang has already passed through the western countries. It must have been experienced by the Mohist sages, and I don''t know if there are records of the western regions." Li Shimin asked.

    Merton understood Li Shimin''s intention. He wanted to point at the western regions!

    Merton shook his head and said, "back to your majesty, it''s a long way from the western regions. I''m afraid it will take four years for the eminent monk Xuanzang to reach Tianzhu, but it took only one year for the Mohist sages to enter from the Tibetan Plateau. When they returned, they chose to return by sea in order to avoid suffering from altitude reaction again. It only took more than half a year to reach Lingnan road."

    "I''m off the road!" Li Shimin and Wei Zheng looked at each other.

    "In order to show his sincerity, master Xuanzang took the initiative to choose the most difficult way!" Merton was deeply influenced by the "9981 difficulty" of later generations and gave the answer he thought most.

    Buddhism has always said to practice hard. Li Shimin didn''t doubt it and nodded.

    "Could it be that your new painting skills that fascinated Yan Liben also came from Tianzhu?" Wei Zheng asked.

    Merton shook his head and said, "Lord Wei doesn''t know. This new painting skill comes not from Tianzhu, but from the far west to the west of Tianzhu."

    "The Far West? Persia?" Li Shimin asked after thinking about the great country in the West in his memory.

    Merton shook his head and said, "it comes from a region west of Persia, which is no less than the territory empire of the Tang Dynasty."

    "Impossible?" Li Shimin and Wei Zheng exclaimed.

    In their historical recognition, China has always been the center of the world and the most powerful country in the world. Now Merton suddenly says that there is a great empire in the world that is no less powerful than Tang Dynasty,

    Merton gritted his teeth and said, "Merton didn''t believe that there was a powerful country comparable to the Tang Dynasty in the world at the beginning, but according to the records of Mohist sages, in this world, Chinese culture can only be regarded as one of them, and three cultural holy places are as old as the Tang Dynasty. Tianzhu is one, Persia and other places are also one, and the great empire in the Far West is also one."

    Li Shimin and Wei Zheng didn''t want to believe this fact. At first, the cultures of Persia and Tianzhu were there, and it''s not uncommon to see another one.

    "Unlike China, Tianzhu and Persia, the Empire in the Far West has been in existence for 1500 years since the founding of the people''s Republic of China. Its culture is prosperous and well preserved, which is unimaginable. The new painting technology is only a trivial one." Merton showed Li Shimin and Wei Zheng a grand world, Directly subverted their imagination.

    "1500 years!" Li Shimin smacked his tongue.

    You know, Chinese dynasties change very frequently, and the longest Han Dynasty only existed for 400 years. Li Shimin was confident that he would not lose to any emperor, but he was not confident that the Tang Dynasty would survive beyond the Han Dynasty.

    Looking at the look in Li Shimin''s eyes, Merton immediately knew Li Shimin''s thoughts, slightly bowed his head and said, "since the Qin and Han Dynasties, the ancestors of the Mohist school have set the rules of the Mohist school, devoted themselves to studying knowledge and no longer participated in politics. Mozi''s secret book does not record the political strategy of the far western country."

    Merton certainly can''t say that the ancient Roman Empire also experienced various changes in the throne. All it retained was the name of Rome, especially the Republic that the emperor hated.

    (at that time, the place ruled by Persia was the territory of the Babylonian kingdom of Cuba, while the Roman Empire included ancient Egyptian and ancient Greek culture.)
