I think the strength of Qin's vertical and horizontal cooperation is indeed stronger than Yue's. The reason why Guigu is so strong is definitely related to the training method. The purpose of ghost valley education is to hope that they will become rivals, so as to promote the continuous progress and breakthrough of both sides and maintain a delicate balance. However, there is no need to hope that both sides will become enemies of life and death. However, this can only make two people realize it themselves. It can't be clearly said that the vertical and horizontal directions are two completely opposite directions, and there must be an intersection, but the intersection can't be too much. This can also explain why Nie Gai and Wei Zhao have completely different choices.

How strong are the two? There are more masters in the Yin-Yang family, but it recalls several rounds of confrontation between the Yin-Yang family and Nie Gai. Both Priestess of Death, Shao Siming and Xing Soul have taken the first step. After all, the Yin-Yang family ended in rout at first. However, the most effective killer team in Zhao Gao's "Trap Assassin Group" in Qin Dynasty topped the list. In order to seek greater power, he gave up his freedom and real name and joined the "net". Zhao Gao gave him a unparalleled sword, mainly eight swords of the King of Yue.

From then on, he was named Jian, which is very powerful, six in one, but he has his own set. Personality, but absolute obedience, everyone has deadly killing expertise, everyone was once a swordsman, and there are six famous swordsman handed down from generation to generation. It can be said that the Six Musketeers are not only powerful, but also very powerful in weapons. Hallows beat many experts in sword notation. Six musketeers beat seven. However, one of the two men took advantage of wood blade. After the fight, six swordsmen obviously suffered internal injuries. However, the murderer just pretended to bear it coldly until Nie Gai and Wei Zhongcai escaped.

The advantage of Six Sword Slaves lies in tacit understanding. If you separate them, they are definitely no match for Nie Gai or Wei Zhongqiang. After all, it's six to two. Many to one is a great advantage in itself. They are all masters again. This shows that the vertical and horizontal strength has reached at least a certain height, but compared with Yue Bajian, I don't know the result yet. After all, the Eight Swords of Yue State have not all appeared, so I think the vertical and horizontal strength of Qin Yue State is really strong. The above is purely a personal opinion.
