"Ding! Because the host is in the fifth level of the reward stage, he has received five task rewards."

"Then according to what you said, if you complete the first level, there will only be one task reward, and the second level will be two tasks. Is this the calculation?"

"Yes, host!"

Ok!

I can only say that I am grateful to the country that does practical things for the common people, allowing him to vote for a five-tier reward directly.

Thinking of this, Wu Lang felt that if he met Mr. Qian again next time, he would definitely let Mr. Qian get on the roof of the car and touch the prismatic cannon on the RV that he had always wanted.

After the excitement, Wu Lang set his sights on the reward items for this mission.

All five items are now in card form.

After rubbing his hands together, he couldn't wait to click on the first card, and the card information was immediately displayed.

Recharge Card: After clicking to use, you can get 50 survival points immediately.

"Wocao! Isn't it?"

Wu Lang felt a little confused.

Nima system is too arrogant this time, right?

He directly gave himself 50 survival points.

There is no rhythm of a wave of sudden wealth.

Say nothing, click to use immediately.

Watching the survival point balance on the system interface soar to 524900 survival points in an instant, he felt richer than ever before.

I feel like I’m about to spend again. The system just said that many new types of products have been added to the mall in this update. I don’t say anything, and I will go to spend after I’m done.

That's right!

"Please call me rich!"

With a good mood, Wu Lang clicked on the second card directly.

Honeycomb Motherboard Voucher: Use this voucher to exchange for Honeycomb Motherboard X1 in the system store for free.

"Wood grass!"

Wu Lang was dirty again.

During this period of time, due to the large number of people added to the shelter, he obtained four subordinate shelters in Mianyang City. During this time, he was considering whether to add a few drones to other teams after saving a wave of survival points.

Now...

The reward from the system was sent directly to his heart.

Quickly opened the system mall, entered the honeycomb machine mother in the search box, and immediately the item he wanted appeared in front of him.

蜂巢机母,产至于2级文明,其内搭配有11架无人机,其中包括2架侦查机、5架运输机、3架战斗机、1轰炸机。

Click the exchange immediately, and the honeycomb machine mother will appear in the system warehouse in the next second.

The shape resembles the oval shape of an alien spaceship...

Do not!

This is an alien product.

Looking at the flawless arc of the honeycomb machine mother in the system warehouse, and the non-glare cold light, Wu Lang's depressed mood disappeared at this moment.

What are mutant creatures?

joke!

He has never been afraid.

There is a kind of calling him positive.

Whoever takes a step back is the grandson.

After calming down his excitement again, Wu Lang quickly opened the third card.

Service robot exchange card: After using this exchange card, you can exchange service robot X100 for free in any A-200/300/10 series in the system store.

"Damn, are you so proud of the system this time?"

10 A-type robots, this is no ordinary Hao, is there any Shenhao?

Wu Lang was so shocked that he couldn't speak now.

Even though there are turbulent waves in my heart, I am uneducated, so I can only use sloppy words to walk the world.

"breathe.."

"breathe..."

One minute later, Wu Lang finally calmed down again.

Click on the fourth card.

Escort Robot Exchange Card: With this exchange card, you can exchange Escort Robot X100 for free in any B-200/20 series in the system store.

"This...."

In this situation, he wants to sing a song, but he doesn't know if it's suitable?

Invincible is so, so lonely...

How, how empty is invincibility...

Standing alone in the cold wind...

Not counting the others, just these 20 guard robots, plus the 5 B-II/100 guard robots from the reckless team, he felt that no matter how terrifying the mutated creatures were, they couldn't stop him from walking at will.

Nothing can stop me, my longing for freedom...

It seems to be the current him.

.......

After reading the four cards, Wu Lang felt like he was going crazy.

Atmospheric, proud...

System YYDS!

"breathe.."

Ok!

He admitted that he had a bad heart, and he couldn't read the last card without waiting for a few minutes.

He even felt that he was already hovering on the verge of fainting. If he was a little stimulated, he might just roll his eyes and lie down.

About ten minutes later, although his whole face was still flushed, he couldn't bear the itching in his heart like being scratched by a cat, so he clicked on the fifth card.

Universal Optimization Card X1: Using this card, you can specify to optimize and upgrade any facility in the bound shelter.

Seeing this, Wu Lang's eyes suddenly lit up.

This thing is definitely a good thing.

Its value is better than the four previous rewards.

certainly...

Others are also very good.

As the saying goes, those who are content are always happy, and he is very satisfied with the rewards he got for this main mission.

"System, I love you so much! I want to praise you like crazy..."

As long as the sky doesn't collapse, the earth doesn't waste and he doesn't grow old, the flattery will not stop.

After describing all the praise words that he could think of at this time to the system, Wu Lang opened the system mall again, entered the B-type robot in the search box, and looked it up.

First of all, the three models of the B-100 series were directly passed by him, and his main focus was still on the B-200.

After all, if you are cheap, don’t take advantage of the bastard. Let’s not say that the price of one B-200 series can be equal to three B-100 series. In terms of performance, one B-200 can at least beat three B-100 series .

The B-200 series of guardian robots are from level 2.5 civilization.

The technological revolution has once again ushered in the manufacturing technology. The whole body is made of liquid metal, which has various characteristics such as memory, self-healing, explosion-proof, and high and low temperature resistance.

More importantly, it is non-polluting and has few side effects, which is much better than the Saints.

Don't say anything, the arrangement of ten men and ten women happens to form four teams. The names start from Wu Liu and go to the back row. Usually, they can be called No. 6 and No. 7 like Wu Yi and the others...

As for the service robot, it is still the same selection method as before, choosing the best and most expensive A-300 series.

The technological level of the A-300 series of service robots has also reached the level of the B-100 type, which can use bionic skin to cover the body, no longer like the previous 100/200, with bare bones, which is very scary at first glance.

The key is that without bionic skin, he can't take it out.

After learning about it, Wu Lang directly selected two maintenance robots, two guard robots, and one medical robot to supplement the original team. For the remaining five, he chose two digging robots and three production robots.

Still the same sentence, leaving professional things to professional people, and letting Wu Yi and the others carry digging tools to dig holes all the time, I feel a little unkind, and now I just liberate them and concentrate on dealing with foreign wars...

Chapter 546 Using Optimization Cards

The use of the last universal optimization card made Wu Lang a little difficult.

The main reason is that he can think of many places that need to be optimized at present, of course, there are three places that are most needed.

Power room, production workshop, control room.

With the continuous expansion of the shelter and the continuous improvement of various equipment, the shelter is powered by a set of cold nuclear fusion batteries, which seems to be no problem at ordinary times, but when most of the equipment in the entire shelter is activated, the entire shelter’s The voltage is also sometimes unstable.

Although there is no problem in using it now, considering the long-term development of the shelter, it is better to solve this hidden danger as soon as possible.

The production equipment in the production workshop is also the same, although it is the so-called professional precision manufacturing machine tool at the Blue Star level.

It looks high-tech, but it's still not enough for the entire shelter full of countless black technologies.

By optimizing and upgrading to a level beyond Blue Star's existing technology, he will be able to use machinery to produce more advanced weapons and equipment. Whether it is to survive in this troubled world or continue his arms business, this choice is undoubtedly the One of the most cost-effective.

Not to mention the control room, the core and most critical place of the entire refuge.

Whether it is the daily control of the shelter or Linger's assistance to him, absolutely no one can replace him.

Even the combination of Wang Kexin, Leng Bing, and Wu Tian can't do it.

Make sure you prioritize upgrading the control room.

In fact, Wu Lang was a little unwilling.

This universal optimization card has no so-called time limit.

In fact, in order to maximize its benefits, it is best to wait until the critical time later to use it.

But think of the three items lying in the system warehouse at this time.

Whether it's an energy cover, an antimatter engine or a solidified mesh cover, which of these three is not awesome?But it has been lying in the system warehouse. If the system warehouse is not a different kind of dust-free space, the flying dust on the three items may have covered a layer by now.

There is an old saying that is valuable when it is used, and if it is not used, even if it is a rare treasure and has no value for itself, it can only be regarded as a waste product.

In the end, after various considerations, he still decided to use this universal optimization card now, and use it on Ling'er.

"System, can this optimization card upgrade the mid-level smart housekeeper?"

"Yes, but because it is an optimized card and lacks the key upgrade code, this optimization cannot directly upgrade the intermediate intelligence to the advanced intelligence."

After listening to the system's explanation, although I feel a little regretful that Ling'er cannot upgrade to advanced intelligence, since I have made a decision, I will not regret it anymore.

It can only be said that nothing is perfect in this world.

A trace of regret is called life.

"System, how to use this optimization card?"

"Host, you only need to provide the system with the optimization card and the name of the item that needs to be optimized, and the system will activate the optimization card for you."

Wu Lang nodded, took out the universal optimization card from the system warehouse, and said to the system again:

"System, I want to use the optimization card, and the optimization target is the smart housekeeper of the shelter."

"Ding! Target locked..."

"Ding! The optimization target has been locked, and the optimization card is being activated for you..."

"Ding! The optimization card has been successfully activated, and the optimization time is 4 frames in Wu Yali."
