However, the explosives they prepared were far from enough. Li Muyang decided to use sugar and wine to blow up the bridge. Sha Kai was thereHe could hear it clearly.

Wang Lanzhi saw that Ku Mei and Li Tianzhu were in love, and tried his best to bring them together. Ku Mei blushed with shame.The department store clerk pulled a large cart of sugar and hurried away. Li Tianzhu passed them by.Li Tianzhu and Ku Mei returned to their station and casually talked about sugar. Ma Bin happened to be passing by. He made it clear that sugar can be used to make explosives, and Li Tianzhu immediately became alert.

He watched the sugar and liquor being transported away with his own eyes before leaving with peace of mind.Sha Kai tried his best and finally broke the rope that tied him.

He lied that he was fishing by the river and accidentally saw the Kuomintang agents.Two ships of sugar were shipped to blow up the Tuojiang Bridge.Luo Xiangqian didn't know how sugar exploded. Sha Kai briefly explained the principle. The agents detonated the explosives first, and then let the liquor and sugar explode.

Luo Qianqian followed and reminded Zhang Biao to leave the boat quickly.Seeing that the boat was coming under the bridge, Zhang Biao did not hesitate to shoot and detonate the explosive package. The explosive exploded and the boat suddenly burst into flames. Zhang Biao was buried in the sea of ​​​​fire.

When Shakai heard the explosion, he ran to the bridge in one breath. Only when he saw that the bridge was safe did he feel relieved.Li Muyang's plan failed again, and he had to take Ye Lan and others to evacuate the scene.

Luo Xiangqian came later and saw the only remaining relics of Zhang Biao. He did not believe that Zhang Biao was dead, so he jumped into the river and continued to search, but Zhang Biao never came back. Luo Xiangqian was so sad that he wished to live.

Zhou Dafeng jumped into the river and persuaded Luo Xiangqian to get ashore quickly, and persuaded Luo Xiangqian to accept the bad news of Zhang Biao's sacrifice.Luo Xiangqiang swam ashore, took off his military uniform, and with tears wrapped up Zhang Biao's military uniform that was blown to pieces bit by bit.
