It turns out that our approach is effective.

A group of us crawled forward slowly and were not attacked again.

I am far away from the team alone. This is because I deliberately stayed away from the team in order to test whether it was safe in the sky.

From time to time I would throw various small objects into the sky. Use this to verify if anyone is still looking at this area.

Every time, no matter what I throw away, it will be instantly smashed into pieces by the powerful attack.

Even hitting a ball of energy will lead to the same outcome. Although the energy group is definitely not as fast as the speed of light, it still has the speed of sound, but it is still penetrated instantly without any suspense.

But seeing this, I was very happy. This shows that the opponent's intelligence is not high, and he will not judge whether the thing is useful, and will attack as long as it flies.

This is very beneficial to us. As long as we are not exposed to the opponent's line of sight, it is estimated that the opponent will not be able to think that we are moving forward under cover.

A group of people crawled cautiously.

The further forward the attack becomes, the more powerful it is. The small pieces of iron I originally threw would just turn into smaller pieces. However, after we advanced about a kilometer, the iron pieces that would have been smashed into pieces would become more powerful. The block was smashed into powder and sprinkled from the sky.

I secretly marveled at the strength of the opponent's attack.

Those iron blocks are not ordinary junk iron blocks, they are high-grade alloy iron.

At that time, the strength of alloy steel was no longer enough, and if the steel continued to be tempered again, the cost of replacement was not proportional to the strength obtained. It is obviously not ideal for a huge interstellar fleet to accumulate such expenses, so scientists once again turned their attention back to iron, which is rich in resources and cheap at the same time.

Iron was once made into steel, but the technology was not strong enough and steel could only be used as a harder tool. However, with the development of science and technology, scientists have discovered that if many newly discovered elements are added to iron, the strength of iron can be increased. Ever increasing and at the same time low prices.

Therefore, people gradually gave up on alloy steel and returned to the old path of ironmaking.

Alloy iron is currently the most commonly used material. Needless to say, those are the few advantages, light weight, high hardness, and strong plasticity. Of course, there are various detailed benefits, which can be changed according to the added elements.

Due to the low price, major construction plants can continuously temper, compress, and fuse alloy iron to continuously enhance its grade at extremely low costs.

The alloy iron I have in my hand is of the highest grade.

Originally this was a snack for Xiaolang and I, but now when something like this happens, someone has to find the way.

I had thrown away all the gadgets before and had nothing to continue testing, so I had to get these precious alloys.

Although I feel a little distressed, overall the reserves are still sufficient. Xiaolang and I have huge appetites. We are very hungry for metal every day and need to eat a lot. This high-grade alloy is a favorite of ours, so we keep a lot of it in our tokens.

The only drawback is that these alloys are not suitable for our food. This can only be used as a snack to satisfy hunger, or to replenish some energy, but if you really want to use it to fill up, it doesn't seem to have much effect.

This thing is to us what chocolate is to ordinary people.
