The feudal hegemonic war destroyed the old order of slavery?

During the Spring and Autumn Period and the Warring States Period, as the last bronze age in China, bronzes gradually withdrew from the historical stage due to the use of ironware and the promotion of Niu Geng. The use of ironware and the popularization of Niu Geng also marked the remarkable improvement of social productive forces. China's feudal economy has been further developed, especially in the north. The leap of productive forces triggered the revolution of production relations. During the Spring and Autumn Period and the Warring States Period, the well field system was gradually replaced by feudal private ownership of land, and was finally established through reforms in various countries. During the Spring and Autumn Period and the Warring States Period, the war of feudal lords for hegemony destroyed the old order of slavery and brought disaster and pain to the people. However, the result of the war accelerated the process of reunification, promoted national integration and accelerated the pace of change. With the growing strength of the emerging landlord class, they successively carried out political reform movements in various vassal States, and the new feudal system was finally established. Qin, the country with the most thorough political reform, became the strongest of the vassal States and later developed into a unified core force. Culture is a reflection of politics and economy in a certain period. During the Spring and Autumn Period and the Warring States Period, economic development promoted scientific and technological progress. Social changes have contributed to the unprecedented activity of ideas and the unprecedented prosperity of literature and art: during the Spring and Autumn Period and the Warring States Period, the old system and the old ruling order were destroyed, the new system and the new ruling order were established, and the new class strength was growing day by day. Hidden in this process and the root of this social change is the productivity revolution characterized by iron. The development of productive forces eventually led to the reform movement and feudal system in various countries. The war for hegemony accelerated the alternation of old and new systems, and promoted the disintegration of slavery and the emergence of feudalism. The war for hegemony in the Spring and Autumn Period was a reflection of the disintegration of slavery in China, which also created conditions for social progress, changes in class relations, the emergence of new systems and the strengthening of national integration.
