The Hellfire Grenade Launcher is a black cylindrical component that looks like it has no effect alone. It cannot shoot flame bombs or bomb high-explosive grenades. Only by assembling it on a gun can it exert its terrible bonus effect.

Wu Yi installed this grenade launcher on Tornado AK, making Tornado AK look a bit out of character, but its attributes have been significantly improved.

Tornado AK - Hellfire: Bronze 3rd grade. Attack power 60-75.

Strike: The shooting speed is +40% after turning on, consumes 20 energy points, lasting for 5 seconds.

Flame bomb: Comes with 10 fire damage in normal attacks, causing double damage to creatures with ghost viruses without consumption.

High-explosive grenade: Fire a high-explosive grenade, causing 100-200 points of damage to enemies within 5 yards. The maximum number of grenades is 10 rounds, and 1 round will be restored per minute.

Hellfire: Fire a grenade with powerful flames, causing 150-300 fire damage, consumes 30 energy points, ranges 10 yards, and buffering time of 30 minutes.

Special Ability: +10% damage to creatures carrying ghost viruses.

Massage: 60 rounds.

Durability 70/70.

Equipment requirements: strength is above 15 points, firearm proficiency is above level 4.

Note: The improved AK47 equipped with U-type magazines is powerful, stable ballistics and fast firing speed, which is an essential weapon to fight zombies. You can enjoy the supreme pleasure of abuse of zombies by just 998. Creating killing is a performance art.

The last item in the silver treasure chest is a tube of mysterious green liquid like a reagent.

Titan Essence: Bronze Fifth Grade. The flesh and blood essence of the giant Titan is condensed, which contains the components 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. Creatures with lower power may explode and die. Giving life bodies can permanently increase the target's 200 health points, 20 strength points, 10 physique points, and may also activate other effects.

The Titan Essence was taken away by Wu Yi, and it was treated the same as the plant Essence and the highly toxic Essence, and it would take effect until it had the chance.

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

Biochemical protective clothing: Bronze third grade. Defense + 40, health limit + 100, reduce damage caused by creatures carrying ghost viruses by 15%, and reduce physical damage by 20 points. Durability 84/84. Equipment requirements: Power above 14 points. Note: The biochemical protective clothing developed by Nuo Lun Company can effectively prevent being scratched and infected by zombies, imitate the skin composition of steel teeth, giant jaws, black steel beasts, etc., and can effectively resist physical damage.

Wu Yi wore this gray protective suit. Although her appearance was not as cool as she had before, the real effect was much better than that.

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

Tracking (third level skill): Level 4 (3+1), tracking a person for 80 minutes or until he dies, during which the target's defense is reduced by 50 points and gaining his field of vision. At the same time, all friendly units within the target's 1000 yards will receive a 20% movement speed increase. If the target dies during the period, Tracking will get a lot of additional skill experience. Consumption of energy, casting distance of 1000, and buffering time of 5 minutes.

With the reduction of defense with tracking, combined with the continuous reduction of the black and white double stars, it is easier to deal with the steel-toothed giant jaw and black steel beast with super high defense, and it is equivalent to improving the output of teammates in disguise, and the soldiers' bullets will no longer be easily bounced away.

The large amount of soul crystals harvested are still used to increase the level of the Suppression Blade, which has increased its quality by one level. It is a qualitative leap from the fifth grade of whiteboard to the first grade of black iron, and the soul crystals consumed are much more expected.

Suppression Blade: Black Iron First-grade. Suppression: Suppression enemy whose combat ability is lower than your own. Each difference is one combat ability level. The physical attack causes an additional 20 absolute damage. Ignore the opponent's defense during attack. Cutting: The suppression effect of Suppression Blade is doubled against tree creatures. Equipment Note: The gold axe and silver axe is not as good as my logging axe.

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

"What is the purpose of creating an upgrade function?" Wu Yi asked.

"You have already discovered that after upgrading the Suppression Blade to the first grade of Black Iron, the soul crystal needed to continue upgrading it is much more expected. It consumes too much and is not cost-effective. The upgrade system has launched this function. You just need to find some materials needed to build equipment and consume a small amount of soul crystals to upgrade the equipment."

"For example, if you find 5 parts of fine iron and 5 parts of century-old hardwood in your hand, you can only consume 10 soul crystals to upgrade it to the second grade of Black Iron. If you purely consume soul crystals to improve it, you will need 100 soul crystals. You can feel the difference between these."

"The upgrade system will not force you to use the creation function to upgrade the equipment level, but this method is obviously much more cost-effective than simply using soul crystals to improve equipment. You should consider it yourself when upgrading equipment." The elf said.

"Then, the materials required for upgrading different equipment are also different. How should you obtain the refined iron and century-old hardwood you mentioned?" Wu Yi asked.

"Sao Nian, the materials used for upgrading equipment are similar, all of which are various special metals, crystals, woods, etc. For example, fine iron, steel raw materials have been refined many times. Almost all civilized and developed worlds have this material, and it often appears in some magical worlds. This material should be available 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 fine iron is generally used to build cold weapons. Although the technology in this world can smelting fine iron, it has no prospects for use, so there is no force or organization that will spend the effort to smelting. After the catastrophe, the world fell into chaos again, and the possibility of having fine iron is even lower."

"The century-old hardwood is derived from trees that have grown for more than a hundred years, oak, peach wood, birch, red oak, hard maple, red yang, beech wood, boxwood, etc., and it can be found in tropical rainforests that have not been destroyed by humans. However, I think you will not have the opportunity to go there to find materials in the newcomer trial. It is better to go back to the Tower of Heaven or enter other mission worlds before finding a solution."

"If the materials needed to create upgrade equipment appear, I will remind you. Remember to collect more of these materials, maybe it will be useful at any time." The elf replied.

"Well, I understand. What about the materials needed to upgrade the guns on me?" Wu Yi said.

"Most of the guns you have been developed and researched by Noren. The materials they use in these guns are mainly a magical metal called ghost magnets. They are made of simulated certain components of the outer meteorite carrying ghosts, with some peculiar magnetic field energy on it, so they can cause additional damage to biochemical ghosts."

"There should be some of these ghost magnets in Noren's company. If you can get the real particles of that meteorite, it can greatly enhance the power of these guns." The elf replied.

"Ghost magnet? I will pay attention." Wu Yi said.
