What is the ending of "Braveheart 2"?

The finale is: Gong Jin is saved and Dongcun is killed.

Tong Jiaru denounced the heinous crimes of the Japanese and finally had a heartfelt vent in his lifetime. Dongcun was speechless in front of mountains of irrefutable evidence. When he heard Tong Jiaru’s request to be drowned in the special high school, Dongcun understood that Tong Jiaru had already learned how to swim, and even if he could hold his breath for a long time, he would not be able to hold his breath for more than ten minutes at most. In the end, he would definitely satisfy his desired death like a charity dog.

Yang Xiao and Guan Dadao arrived. Dongcun got up from the ground. Yang Xiao killed Dongcun with two punches and kicks. Dong Shumei's revenge was finally avenged. Yang Xiao shouted Dong Shumei's name with tears in his eyes. The young master was safe and sound. Tong Jiaru picked up his son and saw Dongcun die in front of him. Tong Jiaru had waited for this moment for too long.

He carried his son home staggeringly. Waterbirds flew happily on the river, and reeds danced with the wind in the bright sunshine. The scene he had seen in his dreams so many times finally came true today. Tong Jiaru is just one of tens of millions of Chinese, but it is precisely because of their persistence and bravery of national integrity that China will stand erect in the world and remain immortal!

Tong Jiaru escaped from danger and struggled to rescue Gongjin:

He looked up and saw Dongcun, whose face was covered with scars, holding the crying little Gongjin hostage. Tong Jiaru was eager to save his son and rushed to catch up. Suddenly, He fell from the roof and fell into the yard. This was the yard where Kurokawa had been killed. In front of him, a vicious dog was waiting for him with its teeth bared, and it opened its mouth to bite. Fortunately, Guan Dadao, Du Xiaomao and Guan Dadao arrived immediately, and Tong Jiaru finally escaped from danger.
