On August 5, 1868, the last group of Brazilian residents concentrated in Erekhin were expelled by the Chinese Independence Army, and the Brazilian residents in Rio Gro Sul were basically cleared, and the land left by the Brazilian residents was also distributed to the retired Chinese soldiers under the administration of the Chinese Independence Army, and the month-long sweep operation was completely completed.

The mopping operation lasted 33 days, and the Chinese Independent Army dispatched the first division, cavalry brigade, and four local garrison brigades with a total of 23,000 troops, to sweep away the non-Chinese residents of Rio Grande do Sul in the posture of a lion and a rabbit, and the white Brazilian descendants, local Indians, and a small number of black slaves were all deported, and during the battle, the sweeping troops expelled a total of 40,000 white and mixed-race Brazilian residents, 23,000 Indians, and 2,000 blacks.

Rio Grande do Sul borders the Brazilian states of Santa Catarina, Argentina, and Uruguay, and of the evicted local residents, 30,000 whites were driven to Santa Catarina, 10,000 whites were deported to Uruguay, and finally 23,000 Indians and 2,000 blacks were deported to the northern part of Argentina, which is located on the border between Paraguay and Argentina.

The deportation of 65,000 residents to the three countries was an order given by Li Mingyuan after careful consideration.

Brazil, Argentina, and Paraguay are de facto allies, and the Chinese Independence Army's attack on Brazilian troops and occupation of Rio Grande do Sul are direct enemies of Brazil, while Argentina and Paraguay, which are allies of Brazil, are de jure enemies of the Chinese Independence Army.

Uruguay is a small country with few people, and the occupation of Rio Gro Gran do Sul by the Chinese Independence Army is equivalent to erecting a buffer line between Brazil and Uruguay, cutting off the possibility of Brazil annexing Uruguay again, and expelling 10,000 white Brazilians to Uruguay, which can involve most of Uruguay's energy and temporarily reduce Uruguay's threat to the Chinese Independence Army behind its back.

The situation in southern Argentina is complicated, the gauchos and local Indians are huge, the white government of Buenos Aires has limited control over the vast and jungled southern region, and most of the Indians living in Rio Gro Sul live in the mountainous and forested areas close to southern Argentina. The upset of the local balance of power forced the Argentine side to devote some of its energies to the affairs of the southern region.

Historically, after the end of the Paraguayan War, Argentina vigorously introduced European immigrants, rapidly improved its national strength, and became a rare rich country in the world before and after World War I.

The Chinese Independence Army is sandwiched between Argentina and Brazil, and if it wants to develop and grow, it can only obtain land from Argentina and Brazil, Brazil has a large population and strong comprehensive strength, even if it is defeated by the Chinese Independence Army on the battlefield in Paraguay, it still has the ability to launch a counterattack, so in the early stage of the development of the Chinese in South America, it is not only difficult for the Chinese Independence Army to obtain land from Brazil but also to face Brazil's counterattack.

Argentina is different, with a population of 1.5 million in South America, it is considered a country with considerable comprehensive strength, but in the continental region,

1.5 million people is just the standard population of a wealthy county, and Argentina's 1.5 million population is mainly distributed in the area near Buenos, the southern region of 7.8 million square kilometers of land, most of which are inhabited by Indians and gauchos, and the white Argentines mainly rely on several important strongholds such as Detucumán to achieve weak control over the southern region, expelling Indians and a small number of blacks into southern Argentina. Before the problem of the gauchos, it was impossible to introduce population for economic construction and slow down the pace of Argentina's development, and then the Chinese Independence Army strengthened the strength of the Chinese in South America through a large number of immigrants, and then it could slowly encroach on the southern part of Argentina and increase the land controlled by the Chinese Independence Army.

The 30,000 Brazilian inhabitants deported to Santa Catarina were mainly elderly, infirm, women and children.

As for the young men, some of whom joined the guerrillas and were killed by the Chinese Independence Army, some of whom were taken as prisoners of war and joined the forced labor of Brazilian soldiers, and some of whom were deported to Uruguay, after several arrangements, the number of young and strong men among the 30,000 Brazilian inhabitants was only about 4,000, and there were very few white Brazilian women of appropriate age.

The number of whites in Rio Gürden Sul is about 50,000, of which less than 5,000 are women of working age, and in addition to 5,000 women of working age, excluding women who start families and have children and raise children, more than 3,000 women who are unmarried or childless are left behind by the Chinese Independence Army and distributed to meritorious soldiers.

Most of the 3,000 white women were between the ages of eighteen and thirty-five, and the more than 3,000 white women who were in childbearing age had a fair-skinned face and conformed to the aesthetics of the Chinese soldiers, so the first batch of meritorious soldiers who did not find a daughter-in-law immediately focused their attention on the three thousand white women, and on the last day before the end of the sweeping battle, most of the three thousand white women left behind were distributed, and only more than 200 white girls who had not yet reached the age of marriage and childbearing avoided the fate of hasty marriage, Li Mingyuan arranged for him to nurse the wounded at the headquarters of the Chinese Independence Army, and taught them to learn Chinese in his spare time.

With the addition of more than 3,000 Brazilian women, the number of Chinese in Rio Gro Sul exceeded 150,000, reaching the pre-migration population, and there were 15,073 newly formed families among the 150,000 people, with 30,000 and 146 people, accounting for one-fifth of the total population, and one-fifth of the population formed families, which alleviated the adverse effects of the imbalance in the gender ratio of men and women in the Chinese Independent Army. The Chinese soldiers who had newly formed families worked the allotted land of more than 300 acres, and the Chinese soldiers who had not married a daughter-in-law trained hard under the leadership of the officer, striving to marry a daughter-in-law in the next distribution.

The 30,000 expelled old and weak women and children not only could not help the Brazilian army against the Chinese Independence Army, but also required the Brazilian government to consume a lot of materials to settle them, even if they were full of resentment against the Chinese Independence Army, they could only curse in their hearts, but in essence they could not cause harm to the Chinese Independence Army.

The completion of the expulsion of Brazilian residents means that the production and construction work of the Chinese Independence Army has been fully launched, and the construction site, resettlement site for retired soldiers, and naval training base ...... After completing the one-month visit and inspection work, Li Mingyuan gave himself a day off to lie in the garden behind his residence to enjoy flowers and fish.
