Chapter 415 Free Upgrade

"Thank you for your generosity." Su Mu doesn't seem to be very comfortable with this kind of situation, or it is a severe social fear who has not actively communicated with people for a long time. When communicating online, he can talk freely, but he must meet people face-to-face. To communicate, it becomes impossible to speak.

After Su Mu uttered such a sentence, she was stunned in place, full of thoughts: what should I say next?

The scene was very embarrassing.

In the end, Su Qi couldn't see it and started to interrupt.

"Brother Zhang, why did you suddenly appear here? I really thanked you just now. If it weren't for you, we would be finished."

Su Qi said and jumped over, pulling Zhang Tuohai's arm, looking like she was ingratiating.

Zhang Tuohai looked at Su Qi and felt a bit of a headache. He was not very good at dealing with girls, otherwise, his ex-girlfriend would not break up.

"I just drove the night road for a while. When I saw there was a shootout here, I stepped in. By the way, why don't you drive away? I don't think their cars blocked the road."

Zhang Tuohai asked.

"Well, our car is still being upgraded at the repair station. This repair station has a disadvantage, that is, the car can't be moved without the upgrade, and we can't force it to drive away. We can only delay here and wait. The car has been upgraded."

After Su Qi finished speaking, she reluctantly pointed to the inside of the repair station.

Zhang Tuohai looked into the repair station, and sure enough, there was a car parked there. Several robotic arms were holding various tools and tinkering with the car.

"Can you upgrade the car here? Is it free?"

Zhang Tuohai's eyes lit up and asked.

"Well, it's free, but you can only choose one aspect to upgrade, and the upgrade time is a bit long, it takes three hours."

Su Qi pouted and said.

"Anything like this?"

Zhang Tuohai was instantly refreshed. He didn't expect to be able to take advantage of the game system here, and to be able to upgrade for free. This is simply beyond expectation.

"Are there no conditions?" Zhang Tuohai continued to ask.

"There are no conditions, just ask if you want to upgrade, then choose the upgrade direction, and then you can wait. I really didn't find any price to pay. My sister has confirmed it several times, right, sister?"

Su Qi said.

"Well, there is really nothing to pay for. I have checked the supplies several times, and nothing is missing."

Su Mu nodded.

"The game system has changed? Or is this a hidden easter egg?"

Zhang Tuohai's heart also moved. He could upgrade one direction of the car for free. Where can such a good thing be found?

His car is now upgraded once, requiring dozens or even hundreds of Level 3 materials, as well as expensive blueprints. If it can be done for free, it will be a huge advantage.

"There is such a good thing, I will try to use it later."

Zhang Tuohai thought while holding his chin.

"How much time is left?" Zhang Tuohai asked.

"There's less than an hour left, 57 minutes to be exact." Su Qi glanced at the lady's watch on her wrist and said.

"Then I'll wait here for a while. By the way, do you have any advice on how to deal with those guys on the opposite side?"

Zhang Tuohai pointed to the three cars on the opposite side.

"No, no, since it was Brother Zhang who solved it, then it's naturally up to you. Whatever you do, we don't have any opinion."

Su Qi said quickly.

"Really, if that's the case, then thank you."

Zhang Tuohai turned around and walked to the back of the cars, checking the unlucky ones.

The last guy who got hit by shrapnel in both legs, had his arteries cut and died from blood loss.

Seeing this, Zhang Tuohai secretly said a pity.

If this guy is not dead, you can ask them where they came from, but unfortunately, there is no evidence of death now.

Since he couldn't ask anything, Zhang Tuohai could only call 001 out to lick the ground.

In front of others, he is not afraid to expose the steam self-propelled machinery.

Anyway, in the face of absolute force, other players dare not come to provoke him, and they will only become his nourishment and accelerate his development.

Su Qi looked at the steam self-propelled machine that dismantled the car back and forth and couldn't help but be amazed. Like a curious baby, she followed the steam self-propelled machine back and forth. Not daring to touch it.

Su Mu looked at the large group of steam self-propelled machines in astonishment, speechless in astonishment.

In her cognition, she doesn't seem to be much worse than Zhang Tuohai. Zhang Tuohai is stronger than her only because the artillery is sharper and the firepower is more intense. In terms of various soft powers, she is stronger than Zhang Tuohai. Yes, when she strengthens this aspect, she will be on an equal footing with Zhang Tuohai.

Now it seems that she is not only far behind Zhang Tuohai in terms of firepower, but also falls behind a lot in terms of soft power.

What are these self-propelled machines?

Why does the shape look similar to the style of the wasteland world?

What do they do?

Can it be used to assist attacks?

If you can attack, will it be very powerful?

Su Mu's heart suddenly raised many questions.

However, she was worried that this was Zhang Tuohai's secret, so she didn't dare to ask, but just stared at the movements of these steam self-propelled machines, trying to infer their function from their behavior.

Soon, her eyes widened.

She found that those steam self-propelled machines were dismantling cars.

"how can that be?"

Su Mu covered her mouth in disbelief.

In her cognition, after those car characters are extracted from the core of the car, they become waste and can only be discarded.

Now it seems that these things can still be used twice.

Those steam self-propelled machines use chainsaws and robotic arms to disassemble cars into pieces, and then turn them into metal ingots and metal parts, which are neatly stacked in the open space, while other steam self-propelled machines will disassemble these. The unwrapped material is transported away.

"How many such machines does this guy have?" Su Mu looked at the steam self-propelled machines in disbelief, "How many hidden means does he have."

"Wait, since this steam self-propelled machine can dismantle cars, can it dismantle other things? If so, can that secret realm blueprint come in handy?"

Su Mu thought about a secret blueprint that he had obtained before.

In that secret realm, she was blocked by a huge steel city wall at the beginning.

She ran around the city wall before she found a gate, but that gate was also made of steel.

She tried her best to open the gate, and even using explosives to blow it up would not help, and it would not hurt the steel city wall at all.

"Can I borrow these machines from him? With their help, the steel gate should be able to be opened."
