Unexpectedly, Su Yu was serious, "My doctoral dissertation is to study how an ordinary traveler can quickly seize power in ancient times, establish a set of handicraft system and the supporting political power system, and let the country move towards the track of the modern state system." ”

"This ...... Unexpectedly, Dr. Su looks elegant and easy-going, but he is a rebellious young man in his bones. ”

Yang Pingfan took a sip of tea and tried to calm himself down, "Anyway, your topic selection is really tricky, that is, Harvard University can tolerate it, if you choose this topic for doctoral dissertation in other places, you will definitely be sent to a psychiatric hospital to let Uncle Yang wake up a few times." ”

"You think I just chose to be different? That's really underestimating me, I am a liberal arts student, I started studying liberal arts from high school Chinese science, I like history, I am familiar with history, but the deeper this feeling is, the more painful it is, China has countless strong civilizations in history that have been interrupted halfway, there have been countless opportunities to turn over, the rebellion of the eight kings of the Western Jin Dynasty, the rebellion of Yongjia, the rebellion of Anshi of the Tang Dynasty, the shame of Jingkang in the Northern Song Dynasty, the Yashan of the Southern Song Dynasty, the swan song of the Southern Ming, but all missed, do you know the pain in my heart when I understand these histories more deeply? Therefore, I chose this topic, at first it was just to comfort my feelings and find a sustenance for myself. Now that I have a living chance, do you think I'll let it go?"

Su Yu's expression was unprecedentedly solemn, so that Yang Pingfan didn't dare to look directly, "That...... Aren't you afraid of causing a butterfly effect if you change history?"

"The butterfly effect? If we can change the situation in which Chinese civilization has been declining and being oppressed in modern times, then what does the butterfly effect matter? Besides, do you want to stay on Zheng He's fleet and return to Nanjing two years later?"

Yang Pingfan hesitated, "Zheng He's trip to the West is a big event, once we intervene, it is not as simple as changing the fate of a few people in the base time and space......

Before he finished speaking, he was interrupted by Su Yu, "Don't forget how we ended up in this time and space, we must do something to death, otherwise we will let Professor Li be jumped by the immortals when we go back?

To tell the truth, Yang Pingfan's heart is moved, the so-called butterfly effect affects time and space, but it was instilled in him by Li Suifeng before, he is a restless person in his bones, although the name is ordinary, but he has never been willing to be an ordinary person, now there is such a great opportunity, how can he miss it? Besides, the lands of the Americas and Australia may be better developed by individuals.

But what makes him feel a little wrong is that the general travel to change history is not the idea of the male protagonist, how did he become instigated by the female partner when he came here?

The plan to change the trajectory of history was so happily decided, and Yang Pingfan was fooled by Su Yu into preparing to do something big. When the typhoon came, the fleet set sail and sailed southward, and the ship traveled for more than ten days and came to the old port, where the lord of the local state of Boni personally led his ministers to the shore to greet him.

Yang Pingfan and Su Yu watched the ceremony, and the lord of Bo Ni just offered a few orangutans caught from the jungle, plus a few straw mats and wood carvings and other local products, and Zheng He rewarded many valuable gifts on behalf of the Yongle Emperor.

The high-quality Jiangnan silk was packed in ten large boxes, and all kinds of gold, silver, and jewelry were packed into one box, which were divided into categories, including jade, silver, and gold. In addition, there is a load of high-grade red robes produced in Wuyi Mountain, Fujian, and a grand banquet is held after the reward ceremony.

Yang Su and the two also attended, this is a necessary link, the Ming Dynasty is the Heavenly Empire, Zheng He is an angel, and now there are immortals to help, Zheng He also found Yang Pingfan during the banquet, hoping that he could show his identity as an immortal, so Yang Pingfan casually threw out a flashbang, and immediately suppressed the local turtles.

The feast was held in the evening, and the sunset slowly disappeared with its tail in tow, and the remnants of the heat were still steaming on the earth. The place of the feast was a makeshift bamboo shed, it was extremely hot, Yang Su and the others were so hot that they were dizzy, and they had no appetite, Yao Guangxiao saw this, and whispered a few words, and after a while, a military servant came over with a plate, on which were two bowls of milky white soup.

Su Yu smelled the fragrance and took a sip, "Hey, this is Qingbuliang?"

Yang Pingfan also stretched out his hand to take it, "Daddy's tea in the morning, and cool in the evening", at this moment, a bowl of refreshing and refreshing is the best way to drive away the summer heat, and it is still Monk Yao. ”

"In this era, there is a refreshing and cool one? Hey, there is also a sweet seed, and the taste of coconut water. ”

"You don't understand this, the history of the birth of Qingbuliang is beyond your imagination, more than 2,000 years ago, the military medicinal diet invented by the military doctor. ”

According to rumors, after Qin Shi Huang unified the six countries, he set his sights on the Baiyue region of Lingnan. He appointed Tu Sui as the main general and Zhao Tuo as the deputy general, and led an army of 500,000 to the south to pacify Lingnan.

The invincible soldiers of the Central Plains were not defeated by the local Yue people, but they were defeated by the hot and humid Lingnan weather, and the army's combat effectiveness was greatly reduced.

In order to replenish the physical strength of the soldiers, the military doctor used lotus seeds, lilies, sand cucumbers, cishi, barley, etc. as raw materials to make a pulp, added coconut water, and made a cool and warm medicinal porridge. ”

Su Yu glanced at Yang Pingfan after hearing this, "I didn't expect you to be so knowledgeable about food?"

Yang Pingfan was triumphant, "It is a great honor to be praised by Dr. Su." After a change of words, he whispered to Su Yu, "Dr. Su, I watched the ceremony just now, and I know why Zheng He is so popular when he goes to the West, this feeling is a gift boy." ”

Su Yu nodded, "That's right, it is clearly written in the history of the Ming Dynasty that Zheng He went to the West, Zhi Fei Hao prospered, and the treasury was empty. That is to say, Zheng He spent a lot of money on going to the West and emptied the treasury of the Ming Dynasty. ”

According to rough statistics, about 2,000 sea vessels were built and rebuilt during the Yongle period. The cost of each of the treasure ships was about five or six thousand taels of silver, so it can be seen that the cost of shipbuilding in the West alone is a huge amount of money.

This is only a part, in addition, for a large number of foreign countries to pay tribute, on the level of reward, the number is extremely considerable, "Yongle Record Volume 119": Ming Chengzu once said: "The court to take the four Yi, should be gracious." In the future, those who pay tribute will be given by grade, although it is not too much. "Typical spending money and losing money to make money.

More than 100 years later, about the second year of Wanli, the book was written, according to the "Shuyu Zhou Consultation Record" written in the archives of the Inner Library, it is recorded that in the Chenghua period of the Ming Xian Sect, at the instigation of a certain eunuch, the emperor also wanted to go to the West to get treasures, and sent people to the military department to ask for Zheng He's historical information on the West, but he did not find it.
