Li Tangshan looked at Zhang Liang solemnly and said: "You must follow the trend of history, otherwise you will be sent by heaven, which is also the mission of history to you." ”

Zhang Liang was taken aback by Li Tangshan's serious expression. Li Tangshan knew that the ancients were superstitious, and he was most afraid of the theory of heavenly send-off, so he really frightened Zhang Liang. Li Tangshan continued: "If I get too involved, it may affect the development of history, there will be a butterfly effect, and I may suddenly disappear. ”

Zhang Liang looked at the serious Li Tangshan with wide eyes and asked, "What butterfly effect?" ”

Li Tangshan patiently explained: "A meteorologist named Lorenz explained the theory of the air system that an occasional vibration of a butterfly's wings in the Amazon rainforest may cause a tornado in Texas in two weeks. ”

Zhang Liang couldn't understand what Li Tangshan said, and hurriedly interrupted: "What is Amazon?" What is Texas USA? What is Tornado? ”

Li Tangshan smiled helplessly, not on the same channel, why is it so difficult to chat, pondered for a while and continued to explain: "Let me put it another way, the butterfly effect means that the very small changes in the initial conditions will make an extremely huge difference to their future state after continuous amplification. Some small things can be confused, and some small things are very important to an organization and a country if they are systematically amplified. ”

Zhang Liang nodded, as if he finally understood Li Tangshan's words this time. Li Tangshan also explained to Zhang Liang little by little, Zhang Liang found that Li Tangshan's knowledge was really unfathomable, better than his teacher Huang Shigong.

Li Tangshan knew what the smart Zhang Liang understood.

Zhang Liang pondered for a while and looked up and said, "It's okay to help Liu Bang, but I have my own requirements?" ”

Li Tangshan nodded and Zhang Liang said.

Zhang Liang nodded and continued: "First, after I helped Liu Bang obtain the country, I have no interest in the country, you have to arrange for me to go to Nanyang to have a look." ”

Li Tangshan knew that Zhang Liangzhi was not in the country, nodded and said: "You have to think clearly, according to the current navigation technology, you will die in the sea." ”

Zhang Liang smiled and said: "I am a person who is afraid of death, I am very interested in what you said about the country that is poisonous, and the country of Great Qin......"

Li Tangshan was surprised that Zhang Liang's heart was so big, it was an incredible thing to reach India and Rome with the current transportation capacity, and he pondered for a while and said: "I only promise to help you find a ship to go to sea, and nothing else may be able to help you." ”

Zhang Liang smiled evilly: "Okay, but you have to tell me everything you know about the body poison and the Great Qin State, and I also want to increase some possibilities for myself to survive." ”

Li Tangshan nodded, so he chatted with Zhang Liang about India and the Roman Empire, Li Tangshan knew that the history of ancient India and ancient Rome was not much, and he could only talk about some very superficial things, but Zhang Liang felt as if he was playing a new world, when Li Tangshan told the earth that the earth was round, Zhang Liang was even more surprised, and his previous worldview of the round world was completely broken.

Li Tangshan didn't dare to say too much, for fear that Zhang Liang would go crazy, and the amount of knowledge of more than 2,000 years would squeeze Zhang Liang's head.

Lu Pheasant didn't get the news of Li Tangshan for a long time, and slowly became impatient, the lustful Liu Bang was even more reluctant to pay attention to her, Lu Pheasant looked at Bo Ji more and more unpleasantly, and saw that Bo Ji's belly was getting bigger day by day, Lu Pheasant knew that Liu Bang was not allowed to mutilate his own flesh and bones, which was also one of the reasons why Lu Pheasant did not dare to do anything to Liu Fei. Bo Ji escaped Lu Pheasant's beating because she was pregnant, and she was still scolded, but Bo Ji still endured it silently.

Bo Ji asked people to bring a message and asked Li Tangshan to help contact Zhou Bo and Chen Ping, she wanted to leave Empress Lu.

Li Tangshan received Bo Ji's message, and immediately knew the seriousness of the matter in his heart, and hurried back to tell Lu Pheasant the good news after saying goodbye to Zhang Liang, and Zhang Liang agreed to help Liu Bang with the good news.

At the end of 206 BC, King Chu Huai ordered Liu Bang and Xiang Yu to divide their troops to attack Qin, and agreed: Whoever enters Xianyang first can become king. Liu Bang passed through Yingchuan and Nanyang, intending to enter Guanzhong from Wuguan. In July 207 BC (the third year of Qin II), Liu Bang led his troops to capture Yingchuan. Han Wang and Zhang Liang joined Liu Bang. Liu Bang asked King Han to stay in Yangzhai (Han's former capital, present-day Yuzhou City, Henan), and let Zhang Liang go south with the army. In September, the army arrived in Nanyang County (present-day Nanyang City, Henan). Nanyang County Shouqi retreated into Wancheng (Nanyang, Henan) to hold on. Liu Bang was anxious to destroy Qin, and saw that Wancheng was difficult to capture for a while, so he planned to bypass Wancheng and continue to advance westward. Zhang Liang thought it was inappropriate and persuaded: "Although you are in a hurry to enter the customs, there are still many Qin soldiers along the way, and they all hold the dangerous terrain. If you don't take Wancheng now, once the Qin soldiers in Wancheng chase after you from behind, at that time, Qiang Qin is in front and the chasing soldiers are behind, it will be very dangerous. Liu Bang took his suggestion, immediately changed the flag, and led his troops to quietly return by taking the path at night. At dawn, Liu Bang's army had surrounded Wancheng. Then, Liu Bang adopted Chen Hui's opinion, and used the technique of attacking the heart to appease Nanyang Taishou, pardon the officials and people of the city, and take Wancheng lightly without blood. Relieved Liu Bang's worries about advancing westward, Liu Bang's army was greatly boosted, and other cities in Nanyang County saw that Taishou had fallen, and they rose up to follow suit and fell in the wind.

Lu Pheasant saw that Li Tangshan brought back good news, so he agreed that Li Tangshan would go to see Bo Ji, but he still didn't feel good in his heart. I completely bankrupted my image in Li Tangshan's heart, and I didn't know how I became like this, looking at the back of Li Tangshan leaving, I silently shed sad tears that only I understand.

When Bo Ji saw Li Tangshan come back, she knew that Li Tangshan's matter was done, and she told Li Tangshan that she was pregnant with his child, and this account was counted on Liu Bang's head.

Li Tangshan gently held Bo Ji's hand and motioned for her to sit down. Bo Ji also told him that Li Tangshan was not Li Tangshan's son, but Liu Bang's son, and Empress Lu deceived him because he wanted to pass on the jade seal on Li Tangshan's body to her son.

Li Tangshan was sad and sad when he learned that he really wanted to, and agreed to help Bo Ji leave Lu, Bo Ji asked Li Tangshan to contact Zhou Bo Chen Ping, these two are the old generals of her ex-husband, and they are worthy of each other, and they can discuss with Zhou Bo Chen Ping how to save Bo Ji.

After Li Tangshan saw Bo Ji, he had already understood the truth of the matter, and found that Lu Pheasant had become something he didn't know, fortunately he didn't hand over the heirloom jade seal to Lu Pheasant, but he couldn't change the course of history, and after thinking about it again, it was safest to hand over the heirloom jade seal to Zhang Liang, and he had to find Zhang Liang again.

Li Tangshan pretended to know that Bo Ji was pregnant with Liu Bang's child and scolded Bo Ji, and then left sadly, without even saying goodbye to Lu Pheasant.

When Lu Pheasant heard that Li Tangshan learned that Bo Ji was pregnant with Liu Bang's child, he left Bo Ji angrily, and he was overjoyed, and he was no longer particularly embarrassed by Bo Ji.
