This time, the People's Army did not adopt the tactic of artillery covering the attack. Because the People's Army's attack speed was too fast, it was only 3 days before it broke through the Huayin defense line, and it immediately launched an attack on the Weinan defense line. The artillery is heavy weapons, and the road in Shaanxi is not good. Therefore, the Artillery Department could not keep up with the speed of the army's advance. However, the People's Army is not an army that can only rely on strong firepower to attack, not to mention that there are a large number of mortars, which are still guaranteed in terms of firepower.

The People's Army's attack on the Weinan defense line was divided into two routes, relying on the fire of mortars on the front, and at the same time sent a force to surround the flanks and launch an attack from the side and rear of the Qing army. It formed a pincer attack with the front attacking troops, killing the Qing army. Moreover, this time, the People's Army went around the side and rear of the Qing army, which cut off half of the Qing army's retreat route. Therefore, a large number of Qing troops were blocked from the route of withdrawal, so they had to surrender to the People's Army one after another. As a result, the Qing army was killed in battle in less than 3,000, but more than 8,000 were captured by the People's Army.

After the two battles, the total number of Qing army killed more than 7,000 people, while the number of captured people was as many as 10. Cen Chunxuan was appointed as the governor of Gansu and Shaanxi for several years. The new army trained was lost to seven or eight in these two battles, with less than 5,000 people remaining, and even one of them could not be collected.

The Weinan defense line is only more than 50 kilometers away from Xi'an, so Cen Chunxuan did not dare to stop in Xi'an, so he immediately led the defeated army the next day, retreated from Xi'an, fled north, and arrived at Fengxiang Mansion first.

After breaking through the Weinan defense line, the People's Army immediately took advantage of the situation to attack and arrived in front of Xi'an City three days later. Since Cen Chunxuan led his army to withdraw from Xi'an at this time, there was no leader in Xi'an City, and naturally there was no resistance. Therefore, the People's Army basically encountered no resistance and occupied Xi'an without bloodshed.

Then the People's Army changed its stable tactics of occupying Shanxi and taking steps forward, and acted very quickly. After occupying Xi'an, only one day later, one division attacked from Xi'an and advanced northward. At this time, the Qing army was powerless to resist, so the People's Army had almost no effort to conquer Wugong, Mei County, Fufeng and other counties along the way, but they did not stop. They just asked the surrendered officials to manage the place well, and waited for the People's Army to send people to take over the place, and then headed northward to Fengxiang Prefecture.

As a result, Cen Chunxuan had just retreated to Fengxiang and had not even breathed evenly. The People's Army had already advanced to Qishan County, which was less than 30 kilometers away from Fengxiang. Cen Chunxuan was immediately frightened and hurriedly retreated from Fengxiang again, fled north again, escaped from Shaanxi Province, and entered Gansu Province. He also ran without stopping, ran more than 300 kilometers in one breath, and ran to Lanzhou Prefecture, the capital of Gansu Province, before stopping.

After the People's Army occupied Fengxiang, it temporarily stopped its progress, but after only 5 or 6 days of stopping, the People's Army sent troops to take over the places along the road and increased its troops, and then advanced north again.

This time, the People's Army did not advance all the way, but divided its troops into several groups and advanced in unison, successively capturing Qingyang Prefecture, Jingzhou, Qinzhou, Jiezhou and other prefecture areas adjacent to Shaanxi, which were only more than 200 kilometers away from Lanzhou. However, the People's Army's attack basically reached its goal, which was to fully occupy Shaanxi Province and push the defense line into Gansu Province. Therefore, it stopped again, and this time it completely stopped attacking and turned to capture the entire Shaanxi Province. Cen Chunxuan breathed a sigh of relief and could finally take a breath in Lanzhou Prefecture.

Although nearly half of Shaanxi Province had not been captured by the People's Army at this time, there was basically no resistance. Wherever the People's Army's troops went, the city prefectures and counties in various prefectures surrendered. More than 10 days later, the People's Army occupied the entire territory of Shaanxi Province and also attacked the four prefectures to the south, occupying some areas of Baoning Prefecture, Taiping Department, Kuizhou Prefecture and other places, completely stabilizing Shaanxi Province.

At the same time, the People's Army also launched a full-scale attack in the Mongolian region. In fact, at this time, the East China Government had already controlled most of Mongolian areas, and only a small part of the northwest had not been controlled by the People's Army. However, the space for Mongolian opposition forces was greatly compressed. After all, although the Mongolian grasslands are vast, the land is vast and sparsely populated, it is not easy to obtain logistics and support. Although there is Russia's support, firstly, Russia was severely damaged in the Far East War, and its national strength has not yet recovered. Secondly, Russia must also take into account the attitude of the East China Government and dare not be bold in supporting the support. Therefore, the strength is really limited. The Mongolian opposition forces' replenishment mainly relies on local areas.

However, the East China Government implemented a policy of cracking down on royal nobles and liberating ordinary herders in the Mongolian region. Although this move made the Mongolian nobles extremely dissatisfied, some people joined the opposition forces because of this, but in the controlled areas of the East China Government, they soon received strong support from the majority of herders. Many young herders also signed up to join the People's Army. Due to the superb riding skills of the herders, they were basically incorporated into the cavalry.

Without the support of ordinary herdsmen, it has been much more difficult for Mongolian opposition forces to obtain replenishment, and they can only loot and maintain it. The main targets of looting are still ordinary herdsmen, and the consequence is that ordinary herdsmen hate Mongolian opposition forces more. Therefore, Mongolian opposition forces have basically lost the ability to assemble more than 1,000 troops and can only disperse into teams of hundreds of people and adopt harassment tactics. On the one hand, obtain replenishment supplies, and on the other hand, it can also be regarded as causing some trouble for the East China government and showing its existence.

The East China Government also adjusted its tactics accordingly, adopting the tactics of setting up strongholds and controlling key points. Although Mongolia has a vast territory, the herdsmen mainly live nomadic life and have no fixed place. Although under the rule of the Qing court, Mongolia was divided into several banner alliances, each with pastures and pastures, which did not disturb each other, because Mongolia is extremely vast, there are still many territories in each banner alliance, and the herdsmen mainly live nomadic life in the territory of their own banner alliance.

However, it does not mean that there is no key point for festivals in Mongolia. In fact, the key point for festivals in Mongolia is rivers and lakes. First, people and horses must have drinking water, and second, the grasslands around rivers and lakes are more abundant and are also excellent pastures. Therefore, as long as rivers and lakes are controlled, the vast areas of Mongolia will be controlled.

Therefore, the People's Army was equipped with fire support troops and a cavalry platoon, 4 trucks, and logistics personnel, a total of more than 220 people. The fire support troops were equipped with 6 general-purpose aircraft and these 6 mortars, such firepower was enough to fight against Mongolian cavalry with a scale of 1,000 people. At the same time, the trucks also strengthened the troops' movement capabilities. Therefore, each stronghold can be set up in a radius of about 100 kilometers. The People's Army has set up a total of 47 such strongholds, which basically control the northwest Mongolian region that has not yet been included in the control of the People's Army. Although there was no suppression of the hostile forces in Mongolia, the loss of rivers and lakes made it difficult for Mongolia to maintain the long-term. In the end, part of them fled to Xinjiang and Gansu, part retreated into Russia, and part surrendered to the People's Army.

After controlling the northwestern Mongolia, the People's Army concentrated its forces and invaded the Tanguwulianghai area from the 22nd Field Army of the Northwest Military Region.

The Tanu Ulianghai area was originally under the jurisdiction of the Zasaktu Khan tribe and the Tohuit leader of the Khalkha Mongol, and was its permanent residence. In the 12th year of Shunzhi in the Qing Dynasty (1655), the Qing Dynasty conferred the Zasak Khan tribe and the Tohuit leader of the Khalkha Mongol, Omubuerdeni as the Zasak Khan tribe and the Tohuit leader of the Torhuit. The Tanu Ulianghai area was also officially incorporated into the Qing Dynasty's territory, and China began to implement effective rule over the region.

In the fifth year of Yongzheng (1727), the Qing Dynasty and Tsarist Russia signed the Treaty of Brensch, which formally demarcated the Sino-Russian border east of Shabindabah in the northern part of the Tannu Ulianghai region. However, after the Second Opium War, Russia forced the Qing Dynasty to sign the Sino-Russian Treaty of Beijing, the Sino-Russia Discussion of Northwest Boundary, and the Ulya Sutai Border Treaty, which occupied about 80,000 square kilometers of land northwest of the Tannu Ulianghai region, but Russia was still not satisfied and passed the plunder.

Seizing trade, illegal gold mining, illegal immigration and other channels penetrated into the southeastern region of the Tanuwulianghai. The Qing court itself was incompetent, so it was unable to curb the infiltration of Tsarist Russian forces. At this time, Russia established more than 70 industrial and commercial enterprises in the Tanuwulianghai area, with more than 150 residential areas and more than 4,000 immigrants. It also set up Ushinsk border officials to manage immigration affairs, as well as churches and schools, which was the strongest region in Mongolia.

Moreover, after the East China Government occupied the Mongolian region, a large number of Russian merchants and residents retreated to the Tanuwulianghai region and formed an army to save the last Russian territory in Mongolia.

However, the East China Government did not leave any fantasy for Russia. The 22nd Field Army invaded the Tanu Ulianghai area and defeated the Russian army. Not only did it completely occupy the southeastern part of the Tanu Ulianghai at this time, but it also advanced westward to defeat the Russian defenders and captured the northwest part of the Tanu Ulianghai that had been ceded to Russia.

Of course, after the East China government recovered the Tannu Ulianghai area, Russia immediately expressed strong protests to the East China government, severely accusing the East China government of violating the Sino-Russia Beijing Treaty, the Sino-Russia Discussion of the Northwest Border Agreement, the Ulia Su-Taiwan Border Agreement and other treaties, requiring the East China government to withdraw troops from Russian territory immediately, otherwise Russia would spare no effort to regain the northwest Border Region of the Tannu Ulianghai.
