In this seemingly ordinary town, even the very nervous Hongying discovered the subtle relationship between Dalu, Piston and Manzhu.Uneasiness and worry prompted her to find the piston and try to unravel this tangled knot.Piston assured Hongying that there was nothing between him and Manzhu, and he would never allow the family that had finally reunited to break up again.

However, fate always seems to play tricks.The Pistons had to retire. Before leaving, he said goodbye to Wu Gang.Looking at Fu Qiusheng participating in the training, he felt that he had no regrets about this military career.When Piston returned home, looking at his son Lu Lu who had both beard and tail, Lu Lu's mother was so distressed that she shed tears.Piston learned from the mainland mother that Manzhu injured her lungs during the earthquake and has not fully recovered until now.

Weidong offered to accompany Manzhu back to the grassland, but Piston chose to accompany Manzhu back to the hunter's point.In the process, they faced not only the hardships on the road, but also each other's inner struggles.Piston's true condition has become a secret, known only to Lu Niang and Hongying.They decided to tell the mainland after Piston's illness was diagnosed, fearing that their son would be unable to bear the successive heavy blows.

On the other hand, Lu Da was entrusted by No. 43 to come to his hometown, but unexpectedly discovered that No. 43's mother had not died.After some twists and turns, Lu Da finally persuaded No. 43 to open the door and successfully persuaded his sister to write a letter to his brother.

With its sincerity and courage, the mainland successfully solved this problem.Piston performed well at work and was appointed deputy station director of the forest farm and railway station for his meritorious service in catching poachers.Just when he thought everything was going in the right direction, he fainted in front of the mainland mother, shocking everyone.

Manzhu decided to confess her feelings, and she wanted to take care of Piston for the rest of her life.Although the mainland mother was heartbroken, she chose to be strong again and accepted Manzhu's decision.Her only request was to wait until Piston's illness was diagnosed before telling the mainland. She was afraid that the successive heavy blows would be unbearable for her son.

On the train platform, Piston discovered traces of poachers. He and Uncle Old Yu teamed up to arrest him. During the process, he was stabbed by the poachers with a knife and was hospitalized in a coma.Beside the hospital bed, Manzhu held Piston's hand distressedly. This time she was no longer afraid of the eyes of outsiders and calmly released her true emotions.Watching this scene, the mainland girl understood that nothing could separate them anymore.
