Eventually, after a few moments of silence, Kara calmed down.

She silently walked to the corner and sat down, like a discarded doll, it was hard to imagine that this was the girl who had just released enough momentum to suppress everyone present, Carla just lowered her head, not knowing what she was thinking.

Glancing at Kara, who had hidden herself in the shadows, Zhang Yu quickly withdrew his gaze.

Zhang Yu is not ready to comfort her, or to help her, not that Zhang Yu's heart is hard, but that he understands that Kara is a mental illness, which cannot be cured with a few words, and he himself does not have this ability.

There are many mental illnesses, but they are generally divided into two kinds, one is that there is something in the heart and needs to be understood and solved by others, as well as a lot of confiding and medication, and the other is a pure disease, which cannot be assisted in treatment through communication, and can only be controlled by medication.

Kara belongs to the latter, but unfortunately there is no medicine on Earth that can control the Kryptonians, so if she wants her heart disease to be cured, she can only reconcile with herself and come out of the tip of her inner horns.

As for now, it's better to let her be quiet for a while, and as for the rest of the matter, let's wait until General Zod is settled.

After a pause, Zhang Yu took out the backpack containing the alien stone that was similar to kryptonite, and saw that several people had cast puzzled glances, Zhang Yu opened his mouth to explain.

"Kryptonians have a different physique from earthlings, our weapons can't deal effective damage to them, and the only way to kill them is to use their weapons, or use this - a mineral that carries red solar radiation."

Hearing this, several people walked over and began to carefully examine these small things that looked exactly like normal rocks.

Old Bruce Wayne, as a weapon master, quickly understood the function of these rocks through Zhang Yu's words, he picked up the stones and looked at them carefully, and found that the results of these stones were very ordinary with the naked eye, and there was nothing special about them, and the specific special ones still had to be further tested.

"This looks like a normal rock." Little Barry Allen watched it for a long time and didn't see a reason.

"The stone is indeed a normal stone, but the point is the radiation it carries." Old Batman gave him an answer. "I don't know what the red sun is, but if the radiation from that thing can really have an effect on the Kryptonians, then I might be able to make a few good treasures out of it."

"Oh, I see, so these stones are 'silver bullets' belonging to the Kryptonians, right, as long as you make these stones into bullets, or engrave them on bullets, you can deal effective damage to them."

"You can understand that, but it's much more than that."

Zhang Yu smiled at Little Barry, and then looked at Bruce Wayne Sr. "Bruce, Kryptonians are very strong and fast, it's hard to hit them with bullets, and if you can't hit them, then these things are no different from scrap."

Bruce Wayne is worthy of standing at the pinnacle of the human race, as he is good at facing all kinds of enemies, he is almost an all-rounder, and he is also proficient in the use of various weapons, so after learning the information of the Kryptonians, he quickly understood the meaning of Zhang Yu's words.

Glancing at the big black umbrella behind Zhang Yu, Old Bruce smiled slightly. "You mean, let me find a way to incorporate these stone fragments into the poison gas of the Dreadpotion, so that the effect of the poison gas can be exerted, and at the same time, it can also limit the abilities of the Kryptonians."

"Yes, I just did a small experiment with Kara, and the results of the experiment proved that the radiation of these stones can greatly weaken the physical fitness of Kryptonians, including physical strength, strength, speed, reflexes, etc., although it will not make them ordinary people, but at least they will not be invulnerable anymore."

"How many more of these stones are there?" Bruce Wayne Sr. asked.

"As much as you want." Zhang Yu replied casually.

Hearing this, Batman immediately raised his head and looked directly at Zhang Yu with his eyes, and Zhang Yu did not show timidity, and looked at him calmly.

Although Bruce Wayne has believed Zhang Yu and others, to be honest, he still maintains the highest vigilance in his heart, as the guardian of Gotham City and the only superhero in this world at present, Batman has no habit of teaming up with others, and has never seen this kind of 'big scene'.

You know, what he faced before was basically a group of crazy people, even if a few of them were beyond the scope of ordinary humans, he could still use his ability to deal with those criminals.

But when he saw Zhang Yu, led by the Flash, who could travel through the timeline and even the multiverse wantonly, the old Batman's psychology had a lot of pressure.

Zhang Yu and the others are indeed on this side of the earth at present, but the world is so big, and the multiverse is innumerable, in case a few crazy people also control these abilities, then can they protect this world.

So after Zhang Yu and the others entered Fort Wayne, Bruce privately conducted various monitoring, psychological evaluation, and coping methods for them.

Barry Allen doesn't have so many fancy intestines, he has always believed in Batman, even if the Batman of this world is not the Batman he knows, but he still obeys his words, so it is very smooth, through the physical examination of the two Barry Allen, Bruce Wayne already has a certain understanding of the speed force.

However, for Zhang Yu's ability and the accompanying Pietro, Bruce Wayne has never found a good opportunity to test them, such as Pietro, according to him, his ability comes from mutant genes, that is, humans have obtained superpowers through mutation, but this kind of thing is unheard of by Batman.

After several rejections of wanting to help Pietro with a physical examination, Bruce Wayne gave up the idea of studying Pietro's blood cells, because he was still wary of Zhang Yao.

This is not just because Zhang Yu is an ally at the moment, and if they are allowed to discover their purpose, it may cause unnecessary misunderstandings.

In the same way, it is also because the origins of these two people are very mysterious, for example, Bruce Wayne has taken out the universe he was born in from Pietro's mouth, which is a parallel world full of despair.

But there is no way to know the origin of Zhang Yu, even Pietro can't say why.

It seems that Petro is just a companion brought out by Zhang Yao from another universe, and this is also the reason why old Batman is a little wary of Zhang Yao.

And Zhang Yu didn't bring anything with him on this trip, and this backpack is even his own, so the origin of these stones is very intriguing.

Zhang Yu also saw that Bruce Wayne was wary of himself, which was also normal, because Batman was extremely distrustful of anyone.

In the comics, because the members of the Justice League have great strength, he is worried that one day he may threaten human safety, and even records the weaknesses of all superheroes except Green Arrow, just because he is afraid that he can have a way to control them when the war is against each other.

In this regard, Zhang Yu sighed helplessly, he never expected that the first problem he faced when cooperating with these 'superheroes' would be a crisis of trust.

So Zhang Yu crossed his arms and said to old Bruce Wayne.
