After weighing all kinds of risks and benefits, Rick immediately gave up this kind of transaction that could make a lot of money at a glance and let himself die in this matter at a glance.

Then the content of the next transaction needs to be carefully considered.

It has to be in short supply outside, not available elsewhere.

In this way, it seems that the only thing that can be traded is a machine.

But what kind of mechanical body to choose needs to be carefully considered.

The volume can't be too big, because Rick is only one person, and he is a ruin that he has entered with a concealed identity, so how to get out is also a problem.

Small in size, but also more valuable, a combination of various factors, Rick said his requirements briefly.

Hearing Rick's request, the team continued to move forward, and soon came to a temporary foothold.

Seeing the leader again last time, there were some traces of the use of surface items on the other party and the surrounding remnants of Halis.

Grain and all kinds of surface food, as well as all kinds of very convenient surface items can already be seen here, and it is estimated that they have also made many transactions with the bridgehead base.

So for Rick's requirements, these people quickly found something that could meet Rick's requirements.

The first thing that appeared in front of Rick's eyes was a very delicate metal orb.

The metal ball, about the size of an egg, is covered with a layer of metal film, and has a relatively raised knob in the middle, and nothing else.

"What is this?" Seeing that the other party took out this metal ball very carefully, Rick suddenly became interested.

"It's a jamming ball, and when you press the knob, you can send out a disturbance wave. Below the first order includes mechanical bodies of the first order. are not immune to this interference wave. The other party explained very clearly. It's the interference waves that can cause those machines to temporarily get out of control.

Although Rick was very excited after hearing this, he looked at the other party's look of wanting to speak and stopped, and it was estimated that there was something to follow.

Sure enough, the Halis remnant with the interference ball in his hand sighed lightly and continued: "But this thing needs to be recharged, and we don't have a charging device, let alone the ability to analyze the operation of this interference wave, so there is a limit to the number of times it can be used. ”

The opponent took out a total of three of these interference balls, and two of them lost their energy and could not be used. Only one can barely emit two waves of interference.

In this way, the value of this thing is greatly reduced.

Rick nodded and put the thing aside, the other party also knew that this kind of thing was not worth much, but it was basically useless to keep it, it was better to exchange it for some soul powder that would never depreciate.

Not much rests next, just miniature tracking bees and thermally conductive detonators.

As the name suggests, tracking bees are a kind of auxiliary micro-mechanical body that tracks and discerns direction and position, and this kind of mechanical body also uses a small amount of energy, but they can collect free energy in the air on their own. Although this self-collection is very slow, it can at least be used repeatedly. It's a more valuable thing.

As for those thermally conductive detonators, they are weapons for human use, and the explosion power is good, but they are also disposable items.

But obviously, these things don't satisfy the value of Rick's bag of soul powder.

Looking at the remnants of Halis, who were a little embarrassed, Rick groaned, raised his eyebrows, and said, "You help me collect these three things, whether they are clean in energy consumption or not, I want them, as long as I can get together about the same equivalent amount." ”

Saying this, Rick has his own considerations.

Not to mention the fact that large mechanical bodies are inconvenient to carry, how to get out of here alone is a problem. While large automata are more valuable and easier to shoot, Rick's first consideration is not value, but size.

If you can't even get out of the ruins, then no matter how valuable it is, it's in vain.

And Rick feels that he won't have more than he can gain this time this time.

There must be something better in those rooms waiting for him to open.

He has a limited carrying capacity alone, so he can only pick the convenient ones first.

"Yes, you don't want to run out of energy or not?" Hearing Rick's strange request, the other party was only slightly stunned, and happily agreed.

For them, these distracting balls and miniature tracking bees that have lost their energy are things that are still not used in the corner, and since the other party is willing to ask for the rags that they don't use, then of course the consequences are happy for everyone.

Asked a few clansmen to find other tribes to trade, and Rick was warmly welcomed by these Sun tribesmen.

Speaking of which, even the empire can't take a lot of soul powder. Because in addition to finding a large number of undead in refining soul powder, there is only one way to obtain it, and that is the soul on the living.

But this practice obviously cannot be recognized by human beings, so even soul powder has become an important material that is banned by the state.

Only some real research scholars may have some inventory after filing, and they have also been all requisitioned by the state, otherwise so many steel-skeleton mechanical bodies are not so easy to manufacture.

The good food and drink were not for the dim light and the dress of the remnants of Halis, who constantly reminded Rick that this was the dangerous ruins of Halis, Rick would have been a guest at an old friend's house in the future.

For two days, Rick was not idle, through a lot of conversation and mutual corroboration, Rick got a lot of details that needed attention, if it weren't for Rick's generosity to buy the useless rags in their hands, if he wanted to know these precious information, it would have cost some money.

Two days later, Rick regained his knowledge of the ruins of Halis.

It's a dangerous and mysterious place, but it's also full of opportunities and resources.

Even the ruins can definitely make many people rich overnight.

There are nine interference balls, eleven miniature tracking bees, and only four thermally conductive detonators, which are still exchanged for some favors from the Sun Tribe.

Thermally conductive detonators may be useless for mechs, but they are a real weapon of mass destruction for humans. Even if it is an ordinary person, if it is used well, it can easily kill a first-order professional.

There are nine interference balls, but only two have energy, but not much.

Micro-tracking bees have the largest number of bees, with a total of seven of them.

Basically, from consumption and energy, you can see the value of these three things in the eyes of the remnants of Halis.

Among them, the micro-tracking bee has the lowest value and is the least used.

The second is the interference ball that can temporarily interfere with the first-order mechanical body, the most powerful, and the most popular is the thermal detonation bomb.

Things sound like a lot, but in fact, a small burden is all solved.

Thermal detonators are hung in a holster on his chest for easy access, and Rick is not going to be stupid enough to sell it to others, but is ready to use it himself.

This thing can only kill first-order professionals, but if it is used well, silently and with tracking, it will definitely make professionals unguardable. And these things don't occupy magic power, and the four of them are thrown out together, which is almost equivalent to second-order witchcraft without consumption.

The miniature tracking bees and interference balls are placed in hidden places on their bodies, and once the robes are covered, there is basically nothing to see.

Bidding farewell to the enthusiastic remnants of Halis, the other party said that basically all the exits that had been discovered were occupied by the Uss Empire, and they were heavily defended, and that if they wanted to get out, they could only go through that entrance, otherwise they would have to dig through a few hundred meters of ground to get out.

Hearing this news, Rick was only slightly disappointed, if before, this was nothing at all, Rick with half-elf blood could move freely in the soil layer, but at this time, Rick, who was already a second-order, could not do this, and it could be regarded as a gain and loss.

Leaving the remnants of Halis, Rick made another trip to the base of the bridgehead, which had been rebuilt, and the busy crowd came and went, as if it had been the massacre of the place two days earlier.

Because of the lack of manpower at this time, the radiation range to the outside world has been shortened to very few places, otherwise according to the previous warning range, Rick would have been discovered a long time ago, but it is precisely because he knows that this place is not ready to be rebuilt now is exactly the same as before, and Rick will come back to take a look.

Looking at the posture of the Uss Empire, one or two group annihilations cannot discourage their will to persevere, and the remnants of the Sun Tribe Halis, who want to come to the surface of humanity in a few days, should also give these pathfinders of the Uss Empire some guidance and warnings.

As long as the Empire is willing to listen, then it will soon be able to find a way to deal with that strange detection of light waves, after all, human beings are a race of creation, even in this predicament, as long as they are willing, they can still find a way to gain a firm foothold.

After a glance from afar, Rick quickly disappeared.

Although he had a letter from the previous bridgehead to prove his identity, it was obviously not appropriate to go out at this time.

What's more, Rick promised the remnants of Haliss that they would meet around here in three days, and let them prove that they were the survivors who survived by luck, so that they could have a chance to get out.

Quickly moving along the passage, Rick is moving fast because he has walked through it once.

Half a day later, Rick was once again on the edge of the steel city.

Before he could get closer, he heard the familiar cries of "clucking" plague chickens.

Rick suddenly showed an expression that he had already expected, since he knew that there were a lot of good things hidden in those buildings, neither the Tali tribe nor the Galactic Sky would let go of these rooms.

If it was before, the Tali tribe would never have participated in such a meaningless waste of time and energy, but because of the precedent of Rick and others entering those metal rooms, it suddenly made these Helis remnants who had been ready to move for a long time go crazy, so after cooperating with the galaxy, these people are committed to unlocking the room, or the way to storm the room.

It's a pity that they don't know that the more they attack, the more creatures die around those metal rooms, the more abundant and powerful the energy of the metal rooms becomes. (To be continued......)
