This involves several reasons:
First of all, in the original work, Yining killed Lou Shuwan's father and brother, which led to the love between Yining and Lou Shuwan. Of course, in the original book, Lou Shuwan's eldest brother died, and Lou Shuheng was considered a wan ku by Yining, so he survived. In the original book, there is nothing about Wu, and Wu naturally will not die.
Although this is adapted from TV, there is nothing wrong with the original. Well, as the original party, we will not analyze the reasons for the original work, so let's analyze it from the TV series.
The situation of Wu Helou Shuheng is different.
As far as television is concerned, Wu committed a crime in Jiangning. What is this place? This is the court's territory and belongs to the court's jurisdiction. Wu has tried to find someone to assassinate him several times. Why was he stopped by his father Wu Chenghou? Because life is at stake, it is very likely that he will meet the official. Sue and Wu are both big businessmen, and there is no shortage of money at home. If this really kills people, it is likely that it will be difficult to get out of the lawsuit. So Wu Chenghou didn't want to kill Yining, which caused countless troubles. Similarly, the reverse is also true. If you kill Wu, it will also cause countless troubles. The Wu family will not let go. No matter what Wu has done, in a society ruled by the court, there is no right to kill people without trial. Yining can report to the government, but he can't kill anyone, or he will pay the price. Moreover, if this matter makes a big noise in Jiangning, the problem will be big.
Then talk about Lou Shuheng. Lou Shuheng's situation happened in Lin 'an.
At this time, Lin 'an was actually occupied by anti-thieves. In fact, there are no laws and regulations in the whole city. In many places, each battalion occupies its own territory, robbing and robbing the people. Basically no one cares, and even internal camps are constantly contradictory. Basically, whoever has the biggest fist makes sense. There is no order.
Under such circumstances, if a person dies, as long as he is not an important figure in the anti-thief, no one will pursue him, and there will be no yamen to arrest people for trial.
So this time is Liu Watermelon's strategist, that is, the position of Badaoying can be ranked in the front, while Lou Shuheng can run some cloth sales business with the help of his sister's nepotism. In this case, if Lou Shuheng is killed, then as long as Liu Watermelon is willing to protect him, the other party will not risk completely turning against the Eight Battalions for an insignificant Lou Shuheng.
Therefore, the key to adopting different ways to the two is that the cost of crime is different and the balance of interests is different. Even if these two people do the same thing, killing Wu is likely to pay the price of life, while killing Lou Shuheng doesn't have to pay any price, so the results of the two people are completely different.
