At first glance, when he heard that he could still trade with the Cosmic Plane System Company at this time, Chai Shuiqing was overjoyed.

But in the next second, when he clicked on his system page, Chai Shuiqing's heart was cold.

She didn't have a few pieces of metal in her hands right now that she could trade with the Systems Company, so could she go to town and buy them now?

However, she had all the thirty taels left in her hand from the pawnshop, and all the money from selling rice was used to buy fish and meat.

Although Chai Shuiqing doesn't know the price of metal here, it seems that this place is limited to ironware, and ordinary people's ironware is recorded.

In this way, it is simply impossible for her to make a deal with the system company.

'System, if you want to know the situation on the Chai family's side, in the absence of metal exchange, with my current situation, what else can be traded? ’

Chai Shuiqing waited for a while, and then heard the sound of the system sound again.

'Upon inquiry, the host energy is too low, and given the host request and based on the investigation of the page, there are now three suitable devices! Please choose! ’

Under the page, Chai Shuiqing saw three small frames, the first one was similar to a telescope, but it was equipped with a lip speech translation function.

The second shape is a bit like a helmet, with similar functions, but because of the material, more energy needs to be deducted.

Look at the third one, two things that resemble lenses, which are pitifully small.

However, this one is the cheapest, with a small dot under the lens, which is a combination of eavesdropping and spying.

Chai Shuiqing pursed her lower lip, none of these three seem to be cost-effective!

'System, that's too much energy, isn't it?' ’

'Host, this is already the minimum configuration, please choose the host as soon as possible! The countdown begins, ten, nine, eight、......'

Listening to the very cold countdown sound of the system, Chai Shuiqing had to click quickly.

'Alright, let's take it!' ’

Chai Shuiqing clicked and chose the third one, and then he felt cold, even getting colder and colder.

'Ding! Congratulations to the host for purchasing a set of listening equipment from the Cosmic Plane Systems Company! Extract energy and start ...... now'

Hearing the initial sound, Chai Shuiqing saw that the various woods and carvings stored in his system's home were disappearing little by little.

Even the wood powder that she had worked so hard to get for days was taken away.

In addition to that, the cold voice sounded again: 'Didididi! In exchange for insufficient energy, the host's own energy will be extracted by default! Start now! ’

As the voice fell, Chai Shuiqing felt colder and colder, and she could even clearly feel that her heat was taken away by a strange suction.

Chai Shuiqing strode into the cave, and then didn't care about it so much, so he lit a fire with local materials.

While she was warming up, she felt her own heat being taken away little by little.

This feeling is not pleasant, and Chai Shuiqing's face is a little pale.

Time flies very slowly, and when the firewood is added I don't know how many times, the feeling of being absorbed by the heat on Chai Shuiqing's body finally disappears.

She distinctly felt her body slowly being warmed by the fire, and just as she was relieved, she heard the voice of the system in her head again.

'Ding! The draw is over! If the Cosmic Plane Systems product is unused, it will be recalled after 24 hours, so please use it as soon as possible! Valid for three days! ’

Three days!

That's too short!

Chai Shuiqing was stunned for a moment, quickly clicked on the lens, and chose to use it immediately!

The next moment, she felt a cold touch in her eyes, as if a super see-through contact lens had been placed in front of her.

Then, Chai Shuiqing found that she could actually hear a sound farther away.

She didn't feel noisy just now, but at this moment, Chai Shuiqing could hear the sound in the distance, so she naturally felt very lively.
