In general, these materials include food materials, ores, herbs, furs, and spars. Of course, there are special materials for smelting gold and medicines, which do not belong to several common types.

Among the various common materials, hedron tends to be the most expensive because the process of forming hedron is not easy, so it is easier to carry super energy. Sparts can be divided into mineral crystals and animal crystals. Mineral crystals refer to naturally occurring energy crystals, including various attribute crystals, and there are various types. Beast crystals refer to the energy crystals produced by living beings, including the dragon crystal of the dragon and the demon core of the demon race.

The mysterious merchant sold Zhang Tong a piece of [Level 4 Geocentritis Crystal], which is a typical mineral crystal, a rare crystal that cannot be produced in large quantities. It only sells for 30,000 gold coins. The price is really not expensive. In the outside world, the value must be higher.

In terms of energy alone, a Level 4 phlogiston crystal is tens of thousands of times stronger than a Level 1 ore. Ordinary first-level magic ore is worth about 20 or 30 gold coins. While energy is not the only measure of a material's value, it is more cost-effective to look at insect nests with a topographic eye than to mine large quantities of low-grade ore.

Zhang Tong wasted no time. He sold the collection of foreign equipment, plus a dozen repaired idle machines, for a total of 60,000 gold coins. This time, the number of extraterrestrial devices is not very large, because humanity defeated terrorists on the space station. The time is too short to be packaged, and the storage capsules are not enough.

Then take a look at the Mystery Shop.

It may be that the mystery merchant has improved their grades, and the quality of their products is much better than before. The ratio of D-rank skill books to D-rank magic items is almost 2-3 times that of the previous one, and there are more varieties to choose from.

Zhang Tong took a fancy to a ranger skill book, a high-level scroll, and a special scroll.

[DD Skill Book: Remnant Sword], Ranger's special skill, learning conditions: 160 points of agility, 100 points of spirit.

[D-rank Skill Advanced Scroll: Swift Wind] to upgrade E-rank skill [Instantaneous] to D-rank skill [Swift Wind].

[Level 3 Backpack Scroll] Upgrade the Level 2 Backpack to gain 30 backpack spaces.

These three things are very expensive. Premium scrolls are relatively inexpensive, requiring only 2,000 gold, DD skill books up to 6,500 gold, and level 3 backpack scrolls cost 15,000 gold.

Zhang Tong did not hesitate to buy it immediately. Backpack scrolls can increase backpack space. The more space you have in your backpack, the more items you can carry, which is great for survival and combat. As for the skill book "[Remnant Sword], it is a good Ranger skill! "Wind Escape" is a thief's skill. Thieves can learn directly from their own skill books. Ranger can also have this skill, but they can't learn it from a skill book. They can only learn step by step from low-level skills.

Zhang Tong first expanded his backpack, then learned and mastered two skills, and spent more than 10,000 gold coins on the scroll to raise his skills to the highest level.

[Shadow Sword Lv5], DD skill, the highest level lv5, obtains blessings from the shadow state, attacks 40%, speed 40%, has a shadow effect, and consumes 5 magic points per second.

[Swift Wind Lv5), a D-level skill, condenses the wind, gets rid of negative states or constraints, and produces an instantaneous effect, with a maximum distance of 500 meters. Consumes 100 mana and has a cooldown of 300 seconds.

Both of these skills are very powerful, among which [Remnant Sword] can greatly increase damage, and it can greatly increase attack speed and movement speed. Zhang Tong was not satisfied with the speed at first. If he blessed the afterimage effect, he would surely reach an alarming level.

Another skill, Wind Escape, is an excellent escape skill. Even if you're trapped by a leash ability, or paralyzed or slowed down, it can be released instantly, and it also teleports.

Both skills are strong, but they have a common drawback.

That is, magic is too expensive.

The Remnant Sword does not cool down and can be opened anytime and anywhere. Costs 5 mana per second. At first glance, it doesn't seem like much. In fact, 300 mana will be consumed in one minute. Zhang Tong's magic is exhausted and can last for more than a minute.

Strong winds can cost 100 mana points at a time. Although the effect is strong, it cannot be used universally.

Lack of magic is hard work!

As a ranger, Zhang Tong's life, strength, physique, agility and even spirit have reached a level that is not weak. Only magic is not well improved. However, there are flaming pork balls made by the chef, which is more than enough to make up for the lack of magic at the moment.

Mastery of these two new skills led to a linear increase in strength. It's time to deal with the top masters of the horror race, and the chances of victory are much greater.

Zhang Tong found several precious and rare D-rank magic scrolls.

[D-Rank Magic Scroll, Magic Mist], D-Rank Scroll, Stimulation will release the D-rank magic skill "Magic Object!"

[D-Rank Magic Scroll: Frost Hand], when activated, activates the Ice Skill "Frost Hand"

[D-Rank Magic Scroll: Waterfall Technique], when activated, the D-rank scroll will activate a water system skill "Waterfall Technique!"

D-level magic scrolls, only lord-level monsters, have a certain drop probability. Monster Lords aren't that easy to find, so D-rank scrolls are valuable in camps, with only some large groups having very small reserves. Zhang Tong bought three at a time. It must be used in battle.

In addition, nothing else is particularly useful to Zhang Tong.

Lin Caiyan bought a D-level skill book "[Priest's Blessing], which can increase the health limit of friendly targets by 20%. If used on Thunder, the health will increase by more than 1000 points, which is an easy thing to do.

Leng Yun bought a skill book, [Thunderbolt Mastery], which is a passive skill. Once learned, it permanently increases the power of Thunder magic by 20%. Du Rongrong bought a D-class summoner skill book, Toninevines, which is a spell that summons poison ivy within range.

Poison ivy can instantly entangle the target, rendering it immobile. They also have strong toxins that further break down biological resistance.

Thunder, Fatty, Lost Dog, Yang Yi, and Scorpio have all added some skills or gear.

Zhang Tong even bought a book or two of good skills about knights and gunfights, because there were no particularly powerful knights and gunfights in the Yellow River. Zhang Tong planned to sell them to Huang Tian and Ye Qianqiu, so that the people could play a greater role in the war.

Shopping at this mysterious shop cost more than 100,000 gold coins, selling robots and alien devices, offsetting more than half, and buying gold coins from the Flame Crystal Flower. Because they are used to grow insect nests, which are considered a common tool for hiring unions, funds can be withdrawn from unions to compensate.

So even though I bought a lot of things, the actual cost was only 30,000 to 40,000 gold coins.

The next morning, Zhang Tong returned to the Xueguang Plain.

Zhang Tong took Yan Jing and went directly to the cave to let the worm nest absorb it.

The energy of the geocentric crystal was too strong, and as soon as the hive swallowed the spar into its body, its whole body squirmed violently, and its originally red body became even more bright red, steaming, as if it was about to be steamed.

The fat man and the lost dog stand guard at the door. When he saw what he saw, the fat man couldn't help but exclaim, "Can this guy digest it? It won't be roasted meat!"

Zhang Tong was also a little worried that mineral crystals could only be used for production, which was beyond the capacity of ordinary creatures, and the geocentritis crystals were quite intense in mineral crystals. But a worm nest is not an ordinary **. It has a certain wisdom and should not be held to death.

The body of the insect nest that had been washed by the steam continued to emit hot gas, and like blowing up a balloon, it suddenly expanded by nearly 30%, reaching the size of a small mountain.

The worm nest frantically absorbs energy, and magic grows faster than ever before.

In the end, it was set at $850,000.

The magic of the nest is directly proportional to the number of Zerg breeding. Currently, this nest can breed 850 Zerg units, which is equivalent to 850 normal Zerg or 170 elite Zerg!

Now that the Worm Hive has bred Elite Worms, they have reached the Gold Elite level, and their health and skills have been greatly improved.

Elite Battle Worms are just as powerful as Elite Mercenaries.

Initially, the ability to heal insects was several times higher than that of chicken ribs. Although healing spells are not as abundant as those of the Terran priests, there is an advantage in healing insects, which is an attribute advantage that the Terrans will never have!

Zerg that breed from insect nests are not summoners or war animals. They are no different from wild monsters, so their attributes are very powerful, and their health and magic are excellent.

The Healing Worm is a Gold Elite with 6000 HP. A cured bug is worth a few priests. As a monster, the cured worm has a strong ability to recover. When the magic runs out, it only takes a few hours to fully recover.

"Very good!" Zhang Tong was very satisfied, "The effect of this spar is far better than imagined!"

The current strength of the insect nest, if the dog clan dares to fight, it will be dead! Investigating worms can be completely popularized in small groups, making it difficult for dogs, people, and thieves to sneak up on them!

Leng Yun looked at the insect nest that was getting bigger and bigger. "It's finally grown like a bird," he said excitedly. With insect nests, we have mastered a lot in the war!"

Zhang Tong nodded and told the mercenary in charge of the guard: "The strength has become stronger, but the consumption has also become several times stronger. Let the mercenaries take good care of it, and don't forget to feed it, so as not to degrade the abilities of the worm nest. ”

"Yes!"

Zhang Tong let the hive breed a large number of zerg, mainly to detect insects, although the strength of the battle bug is good, but in addition to the drilling ability is relatively easy to use, the strength of the mercenaries is not too strong, because the number of hives to breed is limited, and there is no plan to breed in large numbers.

In addition, 30 cured worms were bred in the worm nest. Due to the superiority of magical power, the healing power is not less than twice that of the priest, which is enough to greatly increase the survivability of the army.

"Let's go!"

Hive magic costs extremely fast. The more worms you summon, the more expensive it will be to maintain them. Zhang Tong didn't give birth to all the bugs at once, but he just gave birth to some.

After Zhang Tong returned to the station, he asked the mercenaries to send the scout insects to various places in the Xueguang Plain, and closely monitored the Xueguang Plain.

Two more days passed.

The mercenaries continued to challenge the secret territory, or went out hunting in groups, working and resting in an orderly manner, and the number of Terrans in the Lotus Plain increased to about 14,000 people, basically concentrating the camp's combat capabilities on the middle and upper mercenaries, and all of them were assembled.

This is a force strong enough to compete with other races.

On this day, Lei Ming suddenly approached Zhang Tong: "The alien race has a new move!"

Zhang Tong was a little surprised when he heard the news: "Can't you sit so fast?" 166 Reading Network
