The main reason is that the ancient weighing units are different from our current weighing units, so no one can pick up Xiang Yu's weapons now. One kilogram of Xiang Yu dynasty is now more than 200 grams, so the weapon of 300 kilograms is more than 70 kilograms, which is actually quite heavy.

For example, in ancient times, it was always said that people with seven feet were more than two meters according to the current conversion method, but there were very few people with more than two meters in ancient times, so it can be seen that the conversion method in ancient times is different from that now, but it is also true that the physical strength of modern people is not as good as that of ancient people. Because farming was the mainstay in ancient times, ancient people, both men and women, were very strong, but most modern people were trained.

Moreover, according to historical records, Xiang Yu used to hold more than 200 kilograms of overlord tripod when he was young, so it is not surprising that Xiang Yu was able to fight with more than 70 kilograms of weapons later. Moreover, in history, Xiang Yu was an infinite overlord, and ancient people wore armor when fighting, so the total weight of Xiang Yu added up to more than 200 kilograms.

Moreover, in the era of Xiang Yu, there were many wars, so many soldiers became excellent because of many wars, and Xiang Yu was their leader, so his ability was definitely better than that of ordinary people. Moreover, the weight of Xiang Yu's weapons is recorded in Historical Records. Although there may be some differences, it is not wrong on the whole. And if Xiang Yu really has this ability, fighting with more than 70 kilograms of weapons on the battlefield will also make his soldiers more.
