The 36-episode series chronicles the rise of a family business heir, who transforms from a wealthy, overseas-educated college graduate to a soldier.

The army was led by Communist Party of China in then Japanese-occupied northeastern China and had evolved to be part of the People's Liberation Army.

As most of the scenes were shot in Daxing'anling Mountains in Heilongjiang province, director Li Yin reveals their biggest "enemy" was the cold weather, in a recent Beijing promotional event.

"The temperature was -40 C in winter. Some of the cameras couldn't function as normal under the chilly environment. When we opened the hot food containers, the food would be quickly frozen," recalls Li, speaking about their filming experience there earlier this year.

To shoot around 6,000 explosion scenes, the crew used more than 40,000 prop bullets.

Actor Li Jian and actress Xu Fanxi lead star the series.
