Chapter 218: Chapter 138: Consecutive Level-Ups, Level 19, Tier Three Battle_3

Lin Feng got up, letting Chen Shanshan clean up first, while he checked the attributes of the upgraded equipment:

“Armor-Piercing Cannon Level 18, Red Quality, Brand”

“Basic Attributes: Damage 150, Effective Range 2 kilometers, Damage Coverage 12 meters, Remaining Tungsten Core Armor-Piercing Shells 350; Upgraded to Host Level Limit”

“Extra Attributes: Bullet Recovery 1/1h; Space Magazine 350 rounds; Area Damage (Coverage Radius 12 meters, Center 2 meters Damage 160); Fire Coverage (Six shots per second for five seconds continuously); Armor-Piercing Shell (Armor-Piercing Ability increased by 100%, Damage +10)”

“Note: Can freely switch back to Level 9 High-quality AK”

“Note: Current basic damage has reached Tier Two Red Quality upper limit, next upgrade will continue to enhance bullet damage, but returns will decrease”

After this upgrade, the basic damage smoothly increased to 150 points, equivalent to the Life Value Upper Limit of a Level 19 existence, and further enhancement of shell damage is not possible.

However, the damage is sufficient, plus the extra ten points from the Armor-Piercing Shell, the current maximum damage reaches 160, invincible below Tier Two, unbeatable.

When Lin Feng evolves to Level 19, he can choose to increase the shell recovery speed or expand the ammunition reserve.

However, Lin Feng is more inclined towards the former.

If he can recover one shell per minute, it’s much more useful than expanding fifty rounds of reserve.

Because it’s rare to fire off all 300 rounds at once, but recovering is too slow.

One per hour, only 24 a day, which isn’t enough for Lin Feng to do fire coverage for five seconds, a few bursts and he’d have to wait two to three days to recover.

But if one shell can be recovered per minute, that’s sixty an hour, and it can be fully restored in six hours.

After checking the extreme damage of the Level 18 Armor-Piercing Cannon, Lin Feng then checked another Level 18 Rapid Fire Cannon:

“Rapid Fire Cannon Level 18, Red Quality, Brand”

“Basic Attributes: Damage 110, Effective Range 2 kilometers, Damage Coverage 6 meters, Remaining Explosive Shells 3500; Upgraded to Host Level Limit”

“Extra Attributes: Bullet Recovery 1/1s; Space Magazine 3500 rounds; Area Damage (Coverage Radius 6 meters, Center 1 meter Damage 110); Rapid Pursuit (Automatic Mode Ten rounds per second)”

“Note: Can freely switch back to Level 9 Precision Handgun”

Unlike the Armor-Piercing Cannon’s stingy fifty-round reserve increase, the Rapid Fire Cannon, under Lin Feng’s branding, directly increased by 500 rounds.

The increase from one upgrade is more than the entire reserve of the Armor-Piercing Cannon.

With such a huge reserve of ammunition, even if the damage is just over 100, it is enough to compensate for its lack of damage.

And what Lin Feng ultimately wants is a full 4000 rounds of reserve, to cope with the mutant monster tide on the fourth and fifth floors of the ruins.

Their numbers are in the thousands, densely packed, without sufficient ammunition, if any mistake occurs, like this time’s mutant outbreak, Lin Feng must first ensure he can safely retreat from the ruins, fighting his way back to the surface.

Thus, the number of rounds in the Space Magazine has become a crucial attribute.

Gazing at the Rapid Fire Cannon in his hand, Lin Feng suddenly realized that the so-called Space Magazine, its expanded space, is essentially the same principle as Ding Yi’s previous analysis of Bai Ye’s Spatial Superpower.

The source of the Space Magazine is precisely the vacuum bubble area created when the gunpowder inside the shell rapidly burns upon bullet activation, propelling the bullet forward.

Although this area is quickly filled by the explosion gases of the gunpowder, when the explosion pressure pushes the bullet forward, a vacuum region does exist at the tail.

This is evident when shooting bullets underwater, where the low-pressure area at the bullet’s tail forms a vacuum cavity.

Lin Feng squinted his eyes slightly. If firearms can upgrade to a Space Magazine due to vacuum regions generated during bullet activation…

Then as long as a vacuum area is designed on other equipment or items, could it also be upgraded to have extra space storage attributes?

Thinking of this, Lin Feng slowly raised his head, looking at the Level 17 Rock Horse Battle Car around him.

A bold plan slowly emerged in his mind.

But Lin Feng quickly thought that creating an expanded storage space on an electric car with already low load capacity might not be very useful since adding more items would only increase the weight of the storage box.

Currently, the greater need is for more abundant power.

Not load capacity.

Perhaps finding a better power system in the future, allowing the car to travel at 100 kilometers per hour, would give the extra storage space on the battle car practical significance.

For example, upgrading to a large capacity expansion space on the Green War Battleship to store freshwater resources, both safe and convenient.

Occasional flashes of insight are again negated by Lin Feng. After examining the two guns, he proceeds to consume five Life Value points to continue upgrading the Level 17 filter…

After finishing everything, Lin Feng immediately got up and went outside the car, putting on the sealed battle armor.

By this time, Chen Shanshan had already prepared, and Shen Yue on the opposite car was yawning while raising her shield, walking towards the two.

At 2:50, the three continued to set off, heading towards the cave entrance at the foot of the mountain.

Upon reaching inside the cave, the four Salvation Army members who previously followed the three to clear the first basement level continued to follow, now waiting at the cave entrance.

Their flamethrower is mainly suitable for close combat burning, its effectiveness decreases significantly beyond twenty or thirty meters, making it highly suitable for sudden mutant attacks in the dark space below the third basement level.

But in the cleanup actions, the terrified mutants ran faster than each other, and the moment there was a noise when opening the door, they would immediately dash away.
