In the Marvel universe, Xiangong technology is so developed. Why use cold weapons? I believe all the friends who have seen Marvel comic films know that the most developed country in the nine countries in Marvel comic books has Raytheon's hometown, called Asgard. Asgard's technology is so developed. There is actually a reason why you still use cold weapons.

Let's compare this problem with Wakanda, the most technologically advanced country on earth, and explain this problem. In the story line set by Marvel Comics, Wakanda can't be said to be the representative of science and technology on the earth, but apart from Kerry Empire, the observer race has been ahead of other countries for hundreds of millions of years, but even so, Wakanda has gradually become a cold weapon. We can start with Panther's vibrating armor.

The reason why the weapons used by the fighting troops in Marvel Comics Fairy Palace have gradually turned into cold weapons, in other words, Wa Kanda, whose technology level has exceeded several hundred million years, is still using cold weapons, which is naturally reasonable.

In Raytheon 1, no matter how powerful human guns are, they are basically useless to exterminators. On the contrary, Asgard soldiers' weapons can pierce the body of the exterminator. In other words, the most primitive way of fighting is simple and rude, and it is also the most effective, because all this is on the premise of extremely developed technology, but cold weapons are more useful, which can be said to be returning to nature.

Hella, Thor 3: The death of the gods at dusk is easily defended by the bullets of warships, but the swords of ordinary soldiers can pierce Hella's figure. So, in fact, all kinds of signs show that, to a certain extent, cold weapons are more effective in combat mode, so in the Marvel universe, Gong Xian is so advanced in science and technology that cold weapons are still in use.
