The Golwill Grenade Launcher is a pitch-black, cylindrical component that appears to have no effect on its own, unable to fire either firearms or high-explosive grenades, and can only be used as a formidable bonus when assembled on a firearm.

Wu Yi installed this grenade launcher on the Whirlwind AK, making the Whirlwind AK look a little nondescript, but its attributes have been significantly improved.

Whirlwind AK - Hellfire: Bronze Sanpin. Attack damage: 60-75.

Strafe: +40% fire speed when activated, consumes 20 energy for 5 seconds.

Fire Charge: Inflicts 10 fire damage on normal attacks, dealing double damage to mobs with ghost viruses and no cost.

High Explosive Grenade: Fires a high explosive grenade that deals 100-200 damage to enemies within a 5-yard radius, with a maximum of 10 grenades and 1 per minute.

Golem: Fires a grenade with powerful flames, dealing 150-300 fire damage, consuming 30 energy, a 10-yard radius, and a 30-minute buffer.

Special Ability: +10% damage to creatures carrying the Ghost Virus.

Magazine: 60 rounds.

Durability 70/70.

Equipment requirements: Strength 15 points or more, firearms proficiency level 4 or above.

Remark; The improved AK47 equipped with a U-shaped magazine is powerful, stable in ballistic, and has a fast rate of fire, making it an essential weapon to fight zombies. As long as 998, you can enjoy the supreme pleasure of abusing zombies. Making a killing is a form of performance art.

The last item in the Silver Chest is a tube of mysterious green liquid that resembles a reagent.

Titan Essence: Bronze Five Pins. The flesh and blood essence of the Giant Titan is condensed, which contains the ingredients of the ghost virus and the genes of the Giant Titan, please let the relevant personnel deal with it before using it, otherwise it may bring some negative consequences, and the creature with lower strength may explode and die. Casting it on a lifeform permanently increases the target's health by 200 health and strength by 20, CON by 10, and may activate other effects.

The Titan Essence was put away by Wu Yi, and it was treated the same as the plant essence and the highly toxic essence, and it would play a role when there was a chance.

The silver treasure chest dropped by the giant titan seemed to have exhausted Wu Yi's good luck, and there was no good harvest in the other soul chests that were opened later, the most was a large number of soul crystals, and only a protective suit that fell from the steel-toothed giant jaw could barely comfort him.

Biochemical protective clothing: bronze three products. Defense +40, Max HP +100, 15% damage reduction from creatures carrying the Ghost Virus, and 20 less physical damage taken. Durability 84/84. Equipment requirements: 14 points of strength or more. Note: The biochemical protective suit for zombies developed by Nolun can effectively prevent infection from being scratched by zombies, and imitate the skin composition of steel-toothed giant jaws and black steel beasts, which can effectively resist physical damage received.

Wu Yi put on this gray protective suit, although the appearance is not as good as the protective clothing he got before, but the real effect is much better than it.

Wu Yi also consumed all the remaining soul energy, raising the level of the tracking technique by two levels, and the effect of the skill was significantly improved.

Tracking (Tier 3): Level 4 (3+1), Track a person for 80 minutes or until they die, reducing the target's defense by 50 and gaining his vision, while increasing the movement speed of all allied units within 1000 yards of the target. If the target dies during the period, Tracking will gain a large amount of additional skill experience. Consumes 40 energy, casts 1000 range, and has a buffer time of 5 minutes.

With the defense reduction of the tracking technique, combined with the continuous defense reduction of the black and white double star, it is easier to deal with the steel tooth giant jaw and the black steel beast with super high defense, and it is equivalent to increasing the output of teammates in disguise, and the bullets of the soldiers will no longer be bounced away by the light.

The large number of soul crystals harvested was still used to increase the level of the Suppression Blade, raising its quality by a level, from the fifth grade of the tabula rasa to the first grade of black iron was a qualitative leap, and the number of soul crystals consumed was also unexpectedly large.

Blade of Suppression: Black Iron Grade. Suppression: Suppress enemies whose combat ability is lower than your own, and for each difference in combat ability level, you will deal an additional 20 absolute damage in your physical attack, ignoring the opponent's defense by 10 points when attacking. Timber: Doubles the suppression effect of the Suppression Blade on tree creatures. Equipment Notes: Gold and silver axes, not as good as my logging axes.

"Young man, you upgraded the Suppression Blade from the whiteboard to the black iron product, you finally started the upgrade system to build and upgrade the function, you are blessed!" The elf suddenly came out and shook his head and said to Wu Yi.

"What's the purpose of building upgrades?" Wu Yi asked.

"You've already found out, after upgrading the Suppression Blade to the Black Iron First Grade, the amount of soul crystals needed to continue upgrading it is unexpected, and the consumption of soul crystals is too large and not cost-effective. This feature is introduced in the upgrade system, you only need to find some materials to build equipment, and consume a small amount of soul crystals to upgrade equipment. ”

"For example, the Suppression Blade in your hand, as long as you find 5 parts of refined iron and 5 parts of hundred-year-old hardwood, you can only consume 10 soul crystals to upgrade it to the second grade of black iron, and if you purely consume soul crystals to improve it, you will need 100 soul crystals. You can feel the difference. ”

"The upgrade system also doesn't require you to use the crafting function to upgrade the level of your equipment, but this method is obviously much more economical than simply using soul crystals to upgrade your equipment, so you can consider it yourself when upgrading your equipment." The elf said.

"So, the materials needed to upgrade different equipment are also different, and how to get the fine iron and hundred-year-old hardwood you are talking about." Wu Yi asked.

"In the year of Sau, the materials used to upgrade the equipment are all the same, all of which are all kinds of special metals or spars, wood and other items. Like fine iron, it is a steel raw material that has been refined many times, and it is found in almost all civilized worlds, and it often appears in some magical worlds, and it should be found in the dark world. ”

"Is there any fine iron in this world?" Wu Yi asked.

"Well, the metal smelting technology in this world is very high-end, but refined iron is generally used to make cold weapons, although the technology in this world can smelt refined iron, but there is no prospect of use, so there is no force or organization that will spend effort to smelt it. After the cataclysm, the world is in chaos again, and those who possess fine iron are even less likely. ”

"Centennial hardwoods are taken from trees that have grown for more than 100 years, such as oak, mahogany, birch, red oak, hard maple, red yang, beech, boxwood, etc., and it is possible to find them in tropical rainforests that have not been destroyed by humans. However, I don't think you will have a chance to go there to find materials in the Rookie Trial, so you might as well go back to the Tower of Babel or enter another quest world to find a way. ”

"If there are materials for building upgraded equipment, I will occasionally remind you, remember to collect more of these materials, maybe when it will be useful." The elf replied.

"Well, I understand. And what about the materials I need to upgrade these guns on my body? Wu Yi said.

"Most of the guns on your body were developed and researched by Nolen, and the materials they used in these guns are mainly a magical metal called ghost magnets, which are made of some components of the extraterrestrial meteorite that carries the ghost virus, and there are some strange magnetic fields attached to it, so they can cause additional damage to the biochemical ghosts."

"There should still be some of these ghost magnets in Nolen, and if you can get the real particles of that meteorite, you can greatly enhance the power of these guns." The elf replied.

"Ghost magnets? I'll take notice. Wu Yi said.
