如何使两个以上的列表相交，而不是两个列表相交？

def find_intersection(lists):
    if len(lists) < 2:
        return []

    result_set = set(lists[0])
    intersection_set = set()

    for i in range(1, len(lists)):
        for element in lists[i]:
            if element in result_set:
                intersection_set.add(element)

    return list(intersection_set)

list1 = [1, 2, 3, 4]
list2 = [2, 3, 4, 5]
list3 = [3, 4, 5, 6]

intersection = find_intersection([list1, list2, list3])
print(intersection)  # 输出: [3, 4]
