Chapter 128

After opening it, there was a small control panel.

Earlier, Lu Shu had asked the members to go around and purchase weapons and supplies,

among which this unremarkable black box was the most expensive.

Just such a small thing,

the price it sold for on the black market,

was more expensive than all the weapons and supplies on that entire vehicle combined!

And its true purpose,

was actually a military-grade signal jammer.

Once activated, it could briefly cover signal transmission within an area.

It could even not be detected on satellite maps!

In modern warfare,

especially in small-scale surprise attacks requiring concealment,

a team would always have one warrior specifically responsible for carrying this kind of jammer.

However, the ones carried by individual soldiers were generally small.

And the one in Lu Shu's hand counted as medium-sized.

Pulling up the system exchange panel,

Lu Shu searched carefully,

then among the countless exchangeable skills on the 【Combat Panel】,

he found what he needed.

【Hacker Master (Permanent Skill)】

There were three levels in total,

【Lv1: Hacker Master】, 【Lv2: Hacker Legend】, 【Lv3: God-Level Hacker】.

The exchange points corresponding to the three levels were,

100,000, 500,000, and 1,000,000.

The system on Lu Shu's body,

was ordinary yet not simple.

From daily life to combat,

it encompassed thousands of skills, big and small.

Every skill was divided into 【Temporary Type】 and 【Permanent Type】,

with exchange points ranging from a few hundred to several million.

In fact, even the most expensive skills,

did not require particularly high exchange points.

The main focus was on rich variety and good quality at a low price.

There were no messy task requirements,

nor was any certain level required to unlock items.

It was just simple.

The host could buy it whenever they wanted to use it.

Very good.

After thinking for a moment,

Lu Shu still recharged 1,000,000 points to exchange for 【Lv3: God-Level Hacker】.

After all, the role this signal jammer would play in a while was somewhat critical.

After the exchange,

a blue data light flickered in Lu Shu's eyes.

After a moment,

he took a deep breath,

extended both hands and began rapidly disassembling this black box,

starting to reassemble the complex parts inside.

Then he opened the digital control panel on top,

and his two fingers began constantly tapping the multi-key keyboard on it.

As his two fingers tapped,

strings of mysterious codes constantly scrolled across the blue digital control panel.

Occasionally, Lu Shu would briefly stop, tilt his head, and think for a moment.

Then he would continue tapping.

Ten minutes later.

Lu Shu's two fingers had stopped moving,

and he lightly tapped the last operation button.

Looking at the operation status appearing on the digital control panel,

a look of satisfaction appeared in his calm eyes.

This medium-sized signal jammer had been completely reset by him from the inside out.

The original signal jamming frequency band had been amplified to the extreme,

The coverage range increased from 5 square kilometers to 10 square kilometers.

A full 5 kilometer increase!

Moreover, the signal bands were set by him with 36 layers of cross frequencies.

Signal interference and interception capability was raised to the maximum.

In other words,

as long as this black box is turned on,

everything within a 10-kilometer diameter range will be masked.

Even if satellites are mobilized for detection,

all they would see is a 10-kilometer blank zone.

And Lu Shu made another adjustment.

Within the 10-kilometer range,

signals can be transmitted freely.

But if transmitting outward,

all signals would be interfered with and blocked.

Outside signals also cannot get in!

It's equivalent to turning on the jammer,

forming an invisible 10-kilometer-diameter great bowl, inverted and pressed down.

Even if the other side wants to decipher the interference signal,

they would first have to face those 36 layers of cross frequencies designed by Lu Shu at a 【God-tier Hacker】 level.

However,

the drawbacks are also very obvious.

After all the bands and functions were pushed to the extreme by Lu Shu,

the jammer is basically equivalent to being in an overloaded operating state at all times,

this expensive jammer, which originally could be used continuously for 24 hours,

in this state,

can only last 2 hours,

and then will be completely scrapped due to excessive output.

But 2 hours of time,

is also enough to complete its mission.

After the modification,
