Where did Chen Cang's dark allusions come from?

First, the allusion of "paving the way, making an hour of darkness" comes from Sima Qian's Biography of Historical Records of Huaiyin Hou in the Western Han Dynasty, which means hiding the true intention behind the superficial action, confusing the other side with obvious actions, making the enemy have the illusion and ignoring its true intention, thus winning by surprise. Sometimes, "clear path" can be omitted and "darkness" can be used alone.

Second, allusions.

In the Chu-Han dispute, Xiang Yu relied on his own powerful power, which violated the agreement that whoever entered the customs first was king. He named Liu Bang Hanwang and called himself the overlord of the place of Chu. Liu Bang listened to Sean's plan, and when he returned to Hanzhong from Guanzhong, he burned the plank road, saying that he would never enter Guanzhong again.

Later, Liu Bang worshipped Han Xin as a general. He ordered the soldiers to build a plank road and pretend to attack Guanzhong from it. In fact, he and Liu Bang led the main force to secretly copy the path to attack Chencang, while the garrison commander was not prepared to occupy Chencang. Then invade Xianyang and occupy Guanzhong. As a result, Liu bang realized the agreement of entering the customs first.

The background of "build a paved road and hide the darkness"

Due to the tyranny of the Qin Dynasty, in July of the first year of Qin Ershi (209 BC), Chen Sheng and Guangwu rebelled against the Qin Dynasty in osawa Township. In September, with the support of Xiao He, the magistrate of Pei County, and Cao Can, the warden, Liu Bang rose up and rebelled. His name is Pei Gong, and Liu Bang soon defected to Xiang Liang.

In 206 BC, the war between Xiang Yu and Liu Bang ended. Xiang Yu, relying on his military strength, cracked the soil and enfeoffed 18 princes, calling himself the overlord of the western Chu. In order to trap Liu Bang, who might compete with him for the world, Ba (Jiangzhou, now the north bank of Jialing River in northern Chongqing), Shu (Chengdu, now Sichuan) and Hanzhong (now three counties south of Qinling Mountain in Shaanxi and western Hubei) were sealed under Liu Bang, forcing them to leave Guanzhong.

Liu bang's soldiers in the Han army are eager to return to their hometown as soon as possible, and some weak-willed and impatient people have also fled. Liu bang took the initiative to add fuel to the fire, decided to take advantage of the situation and led the Han army out of Hanzhong to launch the war to destroy the Three Qin Dynasties. Liu Bang took the advice of Han Xin, a general, and made up his mind to raid Guanzhong and compete with Xiang Yu for eastward advancement.
