Besides Tang Li, Peng Yixuan’s custom-made mechanical exoskeleton was also a standard version, and of the same size as Tang Li’s.
However, because Peng Yue was of a robust build, the standard version’s base frame was not suitable for him, and he could only use a custom-made one.
Therefore, his body’s measurements needed to be taken in detail, and he would only receive his mechanical exoskeleton after ten days.
It happened that Tang Li also needed to visit the trading area to see what good items the exchange had put out during her eighteen-day absence and buy them all to store in her space.
Thus, she temporarily parted ways with the Peng father and daughter, agreeing to meet at the underground garage before lunch.
Since the authorities had not yet lifted the weapon ban, there were no weapons or ammunition being sold in the exchange.
High-tech products like flying motorcycles had also not yet been released.
If Tang Li had visited the underground city or Jiang City in her previous life, she would definitely have known:
On the original timeline, brain-computer interface technology and mechanical exoskeletons were developed only after the authorities lifted the weapon ban and were not introduced this early.
In fact, like the genetically modified rice worms, many high-tech products, including flying motorcycles, were brought by survivors from country R after the major earthquake began.
Unfortunately, Tang Li had not visited Jiang City or the underground city in her previous life, so she was unaware of this small change.
However, even though those high-tech products and weapons/ammunition were not yet available, Tang Li still found some small gadgets during her tour of the trading area.
For example, she bought some advanced materials for radiation and electromagnetic pulse protection.
She also bought a set of protective suits, similar to what the Peng father and daughter were wearing, which were thermal, insulating, and radiation-resistant, even fully sealed ones with built-in oxygen tanks.
Suddenly, a small item caught Tang Li’s eye.
“Mind-controlled speaker?”
Tang Li was very curious.
Even in her previous life, she had never heard of such a thing.
After all, it was too small, and in an environment like the apocalypse, things unrelated to survival were not discussed.
The salesman selling the mind-controlled speaker saw Tang Li’s interest and introduced it to her:
“The mind-controlled speaker is an audio device developed based on brain-computer interface technology.”
“Like the mechanical exoskeleton, it can be bound to the user’s brainwave signals. The user can output various sounds imagined in their brain through the mind-controlled speaker!”
Upon hearing this, Tang Li raised an eyebrow, showing great interest.
She asked, “Can any sound imagined in the brain be output through this mind-controlled speaker?”
Although this was not a survival necessity, it was useful to her.
If this mind-controlled speaker truly possessed the function the salesman described, she would no longer have to pretend to be mute when using her disguise to go to the black market.
Seeing Tang Li’s enthusiasm, the salesman became even more energetic.
“Of course, I can give you a demonstration!”
Tang Li did not hesitate and asked the salesman to demonstrate various sounds.
Sounds of wind, waves, streams, the calls of deer, cats, frogs, and even speaking a specific sentence or singing a specific song in a particular person’s voice…
The salesman successfully demonstrated all of them, and they were definitely not pre-prepared.
“Okay, I’ll buy this mind-controlled speaker!”
Tang Li said, handing over her VIP card.
The salesman was overjoyed and said, “Yes, esteemed guest, one mind-controlled speaker costs 150,000 points. We also need to collect your brainwave frequency.”
Tang Li twitched her lips upon hearing this.
This mind-controlled speaker was not a survival necessity, yet it was sold at such a high price, no wonder few people were buying it.
However, for Tang Li, spending these points was worth it.
Using this mind-controlled speaker in the black market, combined with the disguises stored in her space, could completely ensure her identity remained unexposed.
In the black market, with the replication from her space, how many 150,000 points could she not earn back?
Therefore, Tang Li did not say anything and bought it directly.
Similar to the mechanical exoskeleton, because the brainwave frequency for the brain-computer interface needed to be adjusted, she could not pick it up immediately today and could only come back tomorrow.
After browsing the trading area and finding nothing else to buy, as time was almost up, Tang Li left.
In just one morning, Tang Li had spent over 3.77 million points.
The points in her物资调配券 account suddenly dropped to less than 4 million.
Upon returning to the underground garage, the Peng father and daughter had also arrived.
Tang Li then put on the newly purchased thermal, insulating, and radiation-resistant suit and drove home.
