Huang Youhuan's three major teams also guarded the "Savano Blockade" twice. Speaking of the "Savano blockage", we must first talk about the bombing of Vietnam by the US military in those years. After the outbreak of the Vietnam War, the Ho Chi Minh Trail became the only route for transporting supplies between the north and the south of Vietnam. Le Duan, then chief of the General Staff of the Vietnam People's Army, proposed to the KPA commander and Vietnamese Prime Minister Ho Chi Minh to open a new supply line on the Thai border. Because Thailand was pro-American at that time, if this route could be successfully developed, it would definitely be able to play a surprising effect. Ho Chi Minh instructions can try first. After returning to report to the people, the people sent by Le Duan found that the border trail passed through the rainforest, which was difficult to carry out on a large scale, and the troops sent were surrounded and intercepted by the Thai army, and most of them were injured. Enraged, Le Duan decided to take revenge by ripping open the embankment of the Mekong River and causing flooding in Thailand. At first, the embankment was located in Myanmar but close to Thailand, where the embankment was thinner and should work well. But there was too much sediment here to pick it up, so Li Duan ordered the Sixth Division sent to pick up the Savano it was stationed in. The 6th Division blasted and bombed, and finally broke the embankment of the Savano River. More than 60,000 people died, 3 million acres of arable land were flooded, and large areas of Myanmar, Thailand and Laos were affected. Such atrocities by the Vietnamese military junta have provoked unanimous condemnation from Southeast Asian countries. The three major teams in which Huang Youhuan was in delayed the pace of the Vietnamese army's offensive at a heavy price, and won a certain amount of time for the transfer of materials to the people. At that time, Huang Youhuan had not yet joined the three major teams, otherwise with his hot-blooded character, he might have sacrificed his life for the country.

In the summer of 2005, Huang Youhuan learned from his classmate Ji Kexu that Kunbin was going to block the mouth at Savano. Gilcos always speaks with confidence, for example, when he tells a piece of news, he must also play the role of a commentator and add his personal opinion to it. This time, he said to Huang Youhuan: "General Lalong, commander-in-chief of the three armed forces, ordered that the mouth be blocked within three months to return the Mekong River to its original course." On the one hand, it is to pay him back for blowing up the embankment, and on the other hand, it is also to deal with the police! ”

However, this time Ji Kexu was right. Most of the Mekong River is occupied by police, and once the Savano Pass is pierced and the Mekong River returns to its original route, this area will become a flooded country again. Laron is tantamount to repeating the old trick of "using water to control the enemy", but by this time, his role has changed from Vietnamese to Thai.

After getting this information, Huang Youhuan hurriedly reported to his superiors. Since then, Zheng Huang Youhuan's machine gun detachment has twice carried out the task of guarding the Savano plugging project. Lalong had ordered the gag to be completed within a time limit, otherwise it would be dealt with strictly. Even so, the construction period was still very long, and finally in the spring of 2006, Huang Youhuan also received a commemorative medal for the completion of the closure.

Since May 2006, Huang Youhuan has not received any response from the organization. At this time, the army had occupied Bangkok for two months. Huang Youhuan had no way of knowing that the cadres of the security sub-office in Bangkok's southern district had become guerrillas with no fixed residence, and the intelligence work was at a standstill. However, even out of trust in Section Chief Li's personality, Huang Youhuan firmly believes that the organization will not give up on him.

Not only could the organization not be contacted, but Li Jie and Jia Shunkui also went to Doric with their troops, and Huang Youhuan also lost contact with them. Originally, Huang Youhuan was very interested in the intelligence sources and organization of Kipchak. However, if the information you get in hand cannot be sent, the information will lose its value. So, is it necessary for me to stay in Kipchak? By July, there was still no news from the organization, and Huang Youhuan decided to go back to Bangkok's southern district to find Section Chief Li.

At this time, the traffic police corps was running a police sergeant training class, and Huang Youhuan was transferred to be an education adjutant, responsible for compiling the syllabus and arranging weekly classes. Huang Youhuan pondered that if he escaped at this time, the railway line could be full of "military dispatch" agents of the traffic police corps. Knowing the danger, he did not dare to act rashly. When he was worried about how to run, Huang Youhuan met a noble person again!

Huang Youhuan's military school was really not in vain, and his classmate Li Liangxin came to Kipchak to look for him. Li Liangxin's father, Li Youlin, was the colonel of the 7th Detachment of the 3rd Corps at the Commander's Office, and at this time, the unit was recruiting troops in Changhedian. Li Youlin was born in the army, he didn't read much, and his mind was full of feudal ideas in the past. He asked his son to recommend him a competent person to be his deputy. Li Liangxin heard that Huang Youhuan made a special trip to talk about this in Kipchak, and Huang Youhuan naturally agreed, which was the best way to return to Buriram.

One Saturday night, Huang Youhuan took three cronies of the sheriff, carried his two boxes of books, and took the southbound train to Madian and became the deputy head of the ninth detachment. In August, the ninth detachment was ordered to leave for Bangkok.

As soon as the troops entered Buriram, Huang Youhuan wrote letters to the two addresses of Houling and Lili that Section Chief Li had agreed with him - Section Chief Li had repeatedly explained that he could not go directly to the joint at any time. When the troops were stationed in the Quang Ninh area, Huang Youhuan asked for leave and returned to Phongba. Zhang Yusheng's family is at No. 15 Taiping Lane, Ximutou City, and Huang Youhuan wants to go to see if the organization has returned the letter there. Li Jie's wife, Liang Kerong, told him that she had not seen any letters forwarded to him. Leaving Ximutou City, Huang Youhuan went to Qiyuan Gate to find Jia Shunkui, and he didn't have any letters from Huang Youhuan.

stayed in Fengba for a night, Huang Youhuan rushed to Jinsha, and Zheng Hongfei did the same, and there was no letter to him; tossed to Gu Yang again, and found Zhang Yusheng's wife Chen Xiaohui, the situation is still the same. Like a kite with a broken string, Huang Youhuan didn't know where to float, and he was in a hurry. At this time, the third teaching team to which he belonged had already arrived in Huichuan and was ready to go. When I arrive in Anyan, will I have the opportunity to contact the organization? Huang Youhuan hurriedly caught up with the troops. He never imagined that he would come to the Bangkok of his dreams in this way.

Halfway through, the news came that Qumbin's provisional 25th Division had suffered a major defeat in the northern suburbs of Bangkok. This is the Battle of Wanggujie that took place on August 20 north of Nanmo Town. The 156th Brigade of Li Jie and Ji Kexu belonged to the Third Division, and when he heard the news, Huang Youhuan was in mixed feelings. The best outcome is that Li Jie and Ji Kexu are captured, so that they can find the organization. But what if they die on the battlefield?

However, Huang Youhuan couldn't afford to hurt him, and he sighed with emotion. The information he has in his hand has to be sent out quickly. There was no way, Huang Youhuan could only take a risk.
