They are 35mm and 40mm respectively.

Their power difference isn't substantial, but in Oasis Town and even in the Holy Spring Sect's domain, the popular choice is 35mm caliber.

Most grenade launchers also use this caliber.

Moreover, making grenade launchers is quite simple.

There's no need for an accuracy of 0.1mm or even smaller error precision; typically, a cylinder fitted with a striker and launcher suffices.

Many rifles have a dark cylinder attached beneath the barrel, serving as a grenade launcher to supplement the firepower output of a soldier.

It's similar to a signal emitter.

In essence, the grenade launcher delivers a hand grenade with greater precision, projecting it hundreds of meters away.

Although for Late-stage Enhanced People or Evolvers, throwing a stone the size of a fist three or four hundred meters away is not surprising, the issue is that a hand grenade doesn't necessarily explode right upon hitting the target.

It may explode prematurely in mid-air or delay for one or two seconds after landing, giving the enemy time to react.

Moreover, the strike speed isn't fast; if caught by the naked eye, it can be dodged.

Thus, grenades as ranged small firearms are particularly effective for small-scale combat involving tens or hundreds of individuals.

For instance, nowadays in Oasis Town, many factions need to defend their camps or drive away raiders.

As Lin Feng contemplated, the increasingly advanced ammunition production machine before him quickly completed its upgrade:

"Ammunition Production Machine lv22, Orange Quality, Branded"

"Basic Attributes: Automation Level 8/10; Durability 10/10; Currently able to produce ammunition below 35mm caliber; upgraded to Host Level Limit"

"Extra Attributes: Ammunition Production (when raw materials are sufficient, 9mm bullets 3600/h, 7.62mm bullets 3000/h, 12.7mm bullets 600/h, 25mm grenades 300/h, 35mm grenades 200/h)"

"Note: Has become Branded Equipment; next upgrade can choose enhanced upgrade direction: automation level, production efficiency, product caliber, etc."

Lin Feng beamed with pleasure, immediately stepping forward to review the updated product list beside him.

The entire machine exterior now forms a layer of metallic isolation shield, leaving only the upper and lower entrances for the head.

As the raw material entrance, gunpowder is delivered at the top, metal fed at the bottom.

One only needs to press the caliber number to automatically obtain standard ammunition from the device's end.

Upon seeing the product list description, Lin Feng's mind was instantly at ease:

......

"12.7mm heavy bullets, 60g metal, 60g gunpowder; effective range 1500 meters, damage 60 points"

"25mm small grenade, 100g metal, 100g gunpowder; effective range 500 meters, damage area: 1 meter, damage 80 points"

"35mm medium grenade, 150g metal, 150g gunpowder, effective range 800 meters, damage area: 2 meters, damage 90 points"

Such power is enough to kill a Level 16 Evolver with a Life Value Upper Limit of only 120 points, and intimidate a Level 19 Evolver with a Life Value Upper Limit of 150 points.

Although the threat level to Tier Two Powerhouse isn't severe enough to cause significant harm, it's sufficient to protect his camp's safety and prevent raids from raiders and late-stage Evolvers.

Moreover, the consumption of 150 grams of metal and gunpowder enables Lin Feng to produce approximately 6600 rounds of 35mm caliber grenades in a short time.

Even if each is priced at the lowest of 150 points, it equates to a million points worth of business.

Thus, Lin Feng immediately retrieved a bag of gunpowder from the corner and a copper alloy plate, putting them into the machine.

Once the power is connected, the equipment quickly begins to operate.

With a humming noise.

In just six minutes, the first batch of half a fist-sized shells are delivered from the rear exit.

A total of twenty 35mm grenades.

Worth at least 3000 points, equivalent to a downgraded ordinary electric car or three Level 10 Evolution Agents.

It can be called a money-printing machine!

Just as Lin Feng was delighted, waiting to get rich, he realized that only half an hour into production, shortly after the fifth batch of grenades was shipped, the high-speed operating entire equipment suddenly shut down.

Upon checking the control panel, the power was gone.

The ten sets of batteries on the transporter are only sufficient for the ammunition production machine to operate for half an hour.

The follow-up direct power generation from photovoltaic panels cannot use a transformer to start the equipment.

Newly ignited hopes of wealth were again hindered by electricity, seemingly making the trade with Dawn Village imperative.

While Lin Feng was troubled over the power source for industrial equipment production, Chen Shanshan and others returned with bad news.

Dawn Village and Mechanical Village have already restricted shipment.

This resulted in Lin Feng's ordered remaining four vehicles lacking many functions, especially advanced motors and photovoltaic equipment, making the performance of light combat vehicles and heavy truck transporters fall short of the highest standards.

One wave has yet to settle, another rises.

Lin Feng squinted his eyes, looking at the grenade in his hand.

"Let's go, we're going to Dawn Village, to see if they're willing to fulfill the trade."
