Doomsday: Start as a Red Police Commander

[Don’t worry too much. Although there are advanced life-span potions, they are in very small quantities and cannot reach the level of mass production.

The higher the level of life-span potion, the more demanding and rare the materials required in it will be.

For example, the Heng clan of the eighth-level civilization can produce a life-span potion that can extend one thousand years of life, but the quantity is small and the price is expensive, and few people can afford it.

Because the production of this level of life-span potion requires the juice of the Star Core Vine, the quantity of this kind of vine is so small that it is almost impossible to find it.】

"Well, the longevity potion also requires some special raw materials?"

This surprised Qin Nian. He originally thought that the raw materials of the longevity potion were all technologically synthesized substances, but he did not expect that some existing raw materials would need to be used.

[This is natural. Those low-level potions can naturally be synthesized using atoms, but the highest-level ones are not. Civilizations have not yet completely figured out the structure of these raw materials. There is no way to synthesize them. They can only separate and analyze the substances in some long-lived creatures.

Longevity substances are used as raw materials to prepare medicines.】

This Qin Nian is understandable.

For example, the tortoises on Blue Star have very long lifespans. They must have certain substances in their bodies that make them live longer, but as you know, you cannot extract them and use them on other species. Even if they are extracted,

You can't completely figure out the structure of these substances and then synthesize them through molecular synthesis.

Those top civilizations that can isolate the longevity substances of these longevity plants and use them on themselves are already incredible.

Qin Nian couldn't help but sigh, if technology really develops to the extreme, even the yin and yang of life and death can be reversed.

[The so-called life and death is just a term used in the era of backward technology. Taking your human civilization as an example, the average lifespan in ancient times was only forty or fifty, but what about now? You have entered a third-level civilization, and your average lifespan can reach sixty or seventy.

This is the help of technology. After reaching level six and having the ability to research life potions, it will be a qualitative change. 】

Qin Nian nodded in agreement. He could understand, but he had not fully accepted it yet.

"By the way, System, you come from a sixth-level civilization, can you transmit some knowledge about the life field to us?"

[This...] The girl projected by the system raised her eyebrows and hesitated for a moment.

There's drama!

Seeing that the girl did not refuse immediately, Qin Nian knew what he might get from her, and immediately said: "System, you see, only when my life span becomes longer can I have the opportunity to go into space to find the Gunado tribe and bring

If you send it back to them, it's for your own good, right?"

[Actually, these things are not a secret in the universe, they are semi-open. The difficulty lies in whether the equipment you have can support you in refining the materials needed for synthesis. 】

"System, you said that the top level six civilization can mass-produce life-extending potions for four hundred years. Then, do you estimate that with the equipment I have now, what level of life-extending potions can be mass-produced?"

When Qin Nian saw that there was hope, he immediately became enthusiastic.

[The life potion will be upgraded to one level every one hundred years, with one hundred years as the first level and two hundred years as the second level. The Ancient Nadu civilization is considered to be the semi-top level of the sixth-level civilization and can mass-produce three levels of level two life potions. However,

The top level can produce level five potions.

I have observed that the equipment and machines assembled by that girl should be able to extract and synthesize the raw materials for level 0.8 medicine, and can be mass-produced.】

Level 0.8! That means extending the life span by eighty years.

It’s nearly doubled.

Qin Nian's confidence suddenly increased.

[I can transmit to you the principles of aging mechanism and other knowledge, but the molecular synthesis of life-span potions and the ratio of potions and other knowledge belong to the ancient Nadu civilization. I have no right to transmit it. I hope you understand. ]

The system said in a sincere tone.

"These are enough."

Qin Nian can also understand the system, but having this knowledge is enough.

Zhou Qi has inherited the knowledge of how to configure life-span potions. It is not yet known what level of potions she can configure with the knowledge she has inherited. Now that there is an aging mechanism, I believe she can figure something out.

...

The day passed quickly.

"It's finally here."

Qin Nian watched the upgrade countdown, watching the time decrease little by little, and finally reduced to zero.

[Ding dong, upgrade successful!]

[All weapons and equipment recruited by the host are automatically upgraded to level seven! 】

[Congratulations to the host, you have obtained the fifth recruitment building right!]

[Congratulations to the host, you have obtained two general recruitment quotas! 】

.......

[Requirements for upgrading to the next level: 302/1000!]

After activating the light energy core, a series of messages all popped up, all of which were about upgrades.

The next upgrade condition actually requires killing a thousand alien beasts, which will take a long time.

"Fsky, you go to fight against the alien beast team. I will dispatch my forces to assist you later."

Qin Nian immediately contacted Fsky and the others and asked them to lead the team to attack the team of alien beasts that rushed out from the four areas.

Although there are no new recruits for Fsky, the combat devices previously recruited have been upgraded to level seven, and their power far exceeds level six. It should not be difficult to deal with the teams of alien beasts rushing out from four directions in India.

Already.

What's more, Qin Nian plans to wait for large-scale recruitment.

Afterwards, Qin Nian rowed to the battleship column to check out the newly unlocked battle vehicle formation.

The tank armor unlocked this time is still the same as before, there are still two types, and both types are mechas.

good!!

Qin Nian was excited. The only mechas he could use now were the Terror Robot and the Scythe Mecha, but these were unable to deal with high-level alien beasts. This was a worry for Qin Nian. He only wanted these two mechas now.

Being able to have super high killing ability makes you no longer so weak in this aspect.

The level of the Xian Ali Beast is getting higher and higher, but the power of his mecha has become seriously biased. Except for the Chen Nian mecha developed by Qi Bingchen, the other mechas do not have particularly high single-kill capabilities.

My main battle armor is a terror robot. Its highest killing ability is King-level mid-level, but now it is level seven, so it should be a little stronger.

But these cannot satisfy Qin Nian's expectations for mechas. He wants a mecha that can dominate the huge battlefield, a super mecha that can become a sharp sword.

"Long sword power armor and Wolverine light armed robot are the two armors unlocked this time? Don't let me down!"

Qin Nian put away his eyes and then focused on the explanations of these two mechas.
