Everyone at the Jutingxian Observation Post noticed the enemy's unusual behavior and found that a large number of US troops were evacuating down the mountain, so they quickly reported the situation to the director, Zhao Chuang.Subsequently, Qin Jiwei, based on the intelligence provided by Du Wenjin and others, confirmed that the Second South Division had been replaced by the US Seventh Division and took over the defense of 597.9 Heights. This clearly showed that the US military could no longer support it.Qin Jiwei immediately called Wang Jinshan and asked for more time to have a more comprehensive understanding of the position.

At the same time, Duan Xianfeng went down the mountain at night and went to the artillery position of the 15th Army alone. Not only did he apologize and thank Gao Fengliang for the previous misunderstanding, he also handed over the US military training manual he had translated and wrote it in the notebook.Recorded his own opinions.As a result, the two men eliminated the estrangement and decided to work together to deepen the research on infantry and artillery coordination tactics and jointly contribute to killing the enemy.

When Hu Mancang was organizing a party member meeting, he unexpectedly learned that Shuangxi had expressed his desire to join the party, and asked him to write an application for joining the party.On the other side, Jin Zhuxuan, commander of the 31st Regiment of the Second Korean Division, came to exchange defense with Tiger.Tiger warned Jin Zhuxuan not to underestimate the Chinese army, because they can always attack at unexpected moments, but Jin Zhuxuan did not take this seriously and confidently believed that he could deal with the volunteers who had run out of ammunition and food.

Since the artillery finger had been moved, Duan Xianfeng took on the task of maintaining contact with the Jutingxian Observation Post.Du Wenjin observed closely at the front line and reported the actual situation to Duan Xianfeng in detail. At the same time, he asked with concern about the food reserves in the tunnel, hoping that the soldiers could persevere.Although Duan Xianfeng expressed his determination to persevere, he knew in his heart that the troops had been without water for many days and there were not even many compressed biscuits left.

Soon, Jin Zhuxuan ordered a feint attack on all the tunnels of the Volunteer Army, and implemented continuous and fierce artillery fire coverage.Kim In-pyo believed that this move was too dangerous and suggested withdrawing to Jiwoong Mountain, but Kim Joo-hyun refused.Duan Xianfeng judged from the artillery fire information coming from various tunnel positions that the Korean army's attack was actually a bluff, and its real target was probably their position.

Faced with this severe situation, Duan Xianfeng immediately made arrangements: Hu Mancang led the wounded to hide deep in the main tunnel for refuge; Feng Yugang led the fire team to guard the entrance of the tunnel; he personally took people out for reconnaissance.At the same time, he left instructions that if he failed to return in time, Shuangxi would detonate the explosives in the tunnel to block the enemy's attack and ensure the safety of the tunnel.

The Korean army led by Kim Joo Hyun quickly surrounded the tunnel and threw gas bombs inside.Volunteer soldiers covered their mouths and noses with wet towels and fought to the death with enemies wearing gas masks.Although they fought one after another and suffered heavy casualties, they still stubbornly blocked the enemy from the entrance of the tunnel.

Duan Xianfeng urgently called for rear artillery support. After receiving the order, Gao Fengliang quickly organized infantry and artillery coordinated operations and successfully repelled the Korean offensive.However, a new round of bombing followed immediately. The tunnel was crumbling in the violent explosion, and the wounded fell into extreme fear.At the critical moment, Feng Baisheng led everyone to sing the "War Hymn of the Chinese People's Volunteers", and their singing was particularly loud amidst the sound of artillery fire.

As the Korean army attempted to starve and thirst the volunteer soldiers to death by besieging the tunnels, living materials in the tunnels, especially water resources, became extremely scarce.Under this situation, the soldiers still maintained an optimistic spirit: the sick and wounded relied on water seeping from the stone walls to maintain their lives; other soldiers quenched their thirst by drinking “Glory Tea”.When discussing the next step of action with Hu Mancang, Duan Xianfeng expressed his firm belief in holding on to his position, believing that it would be difficult to regain the position once he retreated.

At the same time, Qin Jiwei personally visited the field hospital and witnessed the tragic rescue scene and the tenacious will of the wounded.He felt deeply sad and heavy, especially when he saw the wounded who, even though they were physically disabled, still cared about the country.Shortly after returning to the headquarters after donating blood, Qin Jiwei received another call from Wang Jinshan.He said with emotion that although he and the soldiers were all tested steel warriors, many of the soldiers were new recruits on the battlefield, and behind them were countless families.At this time, the Eighth Company received news that they were running out of ammunition and food and asked for instructions. Qin Jiwei fell into deep thought.
