Li Yuan rubbed his hands, came to the red zombie, squatted down and picked up the ball of light.

There are three photospheres.

He clasped his hands together, muttered a blessing from Taishang Laojun in his mouth, and then opened the first ball of light

【Copper Ore Treasure Map (Remnant)】

Broken Copper Mine Blueprints, collect three Copper Ore Blueprints to form a Copper Ore Treasure Map.

Follow the map and you'll get a Copper Mine.

(Tip: Copper ore is one of the necessary materials to upgrade intermediate provinces, and it is extremely valuable)

"Another broken drawing."

Li Yuan raised his eyebrows, counting the previous one, he already had two drawings, and only the last one was needed to synthesize a complete treasure map.

But the drawings are hard to find, and Li Yuan killed not a thousand but eight hundred zombies, so only these two were exposed.

Copper ore is one of the main materials for upgrading realms above the fourth order.

Now in the trading market, one unit of copper ore has been speculated to 10 second-order death crystals, but it is still in short supply.

It also reflects that the big guy in the Adventist is really a lot, Lu Yuan is only a third-level territory, and he is still one level away from the fourth-level, and others have already begun to prepare upgrade materials for higher-level territories.

That's the gap.

"Wait for my Underworld Pool to be upgraded, and let you know what it means to be thirty years east and thirty years west of the river."

Li Yuan muttered quietly, not discouraged.

He then looked at the second orb of light.

"Hey, why is the color of this ball of light different?"

Li Yuan found that the color of the second light ball was a little yellowish, while the color of the ordinary light ball was white.

"Is it a high-quality treasure?"

Li Yuan's eyes lit up.

Among the treasures of the Endless Continent, ordinary quality treasures are the worst, also known as tabula rasa.

On the top, there are also good products, top grades, fine products, and excellent products, corresponding to yellow, blue, purple, and red respectively.

Li Yuan hurriedly opened the second ball of light.

A faint yellow light shone on his face.

【Zombie Armor (Good Product)】

Defense +10

Speed - 10

Can resist ten attacks from monsters below the fifth order

The current number of blocks is 10/10

"I'll go, it's really a good treasure, and it's also a defense-type equipment."

Li Yuan looked overjoyed.

That's exactly what he needs most right now.

With this equipment, Li Yuan will not fight every time, he only dares to hide behind and watch, with a certain amount of life-saving capital, he can also attack hard at critical moments to help his subordinates clean up monsters.

Li Yuan happily put the zombie armor on his body.

The armor feels very silky, and it fits well on the body, and there is no uncomfortable feeling, but it is a little heavy.

But with Li Yuan's third-order strength, he can still withstand it.

"Let's look at the last thing."

Li Yuan then set his gaze on the last ball of light.

He reached out and opened the ball of light.

Li Yuan looked at the items inside the ball of light and fell into deep thought.

"Am I being pampered by Lady Luck today?"

【Corpse Fly Class Building Blueprint (0 Stars)】

When used, you can build a Corpse Fly Barracks.

20 corpse flies can be recruited per day.

(A class that can't even kill a dog, the only effect may be disgusting)

Inside the third ball of light, there is actually a class building blueprint.

This is the first time in Li Yuan's three days that he has cracked down on monsters and exposed the architectural drawings of the troops.

According to the statistics of many adventers in the chat channel, the odds of winning the lottery are comparable to winning the lottery by fighting monsters and breaking out the architectural drawings of the troops.

But this chance was also encountered by Li Yuan, and he really didn't know what to say.

The only fly in the ointment is that this class building blueprint is the most rubbish 0-star building.

Dogs hate that.

Li Yuan is not a novice who doesn't understand anything now.

I probably also understand that between the arms, quality represents potential and combat power.

A 1-star first-order class has a promotion speed that is faster than that of a 0-star first-order, and its combat power is also about 10%-20% stronger than that of a 0-star first-order.

For example, the fourth-order red zombie just now.

The grade is at least about four or five stars.

That's why you can easily kill four big skeletons with one enemy and four.

If it is a nine-star first-order class fighting against a one-star first-order, Li Yuan estimates that no matter how many one-star first-order troops there are, it will be in vain.

The higher the star, the greater the gap.

This is also the reason why so many lords have upgraded their realms to level 4 or even higher.

The initial class potential recruited by the Pool of the Underworld is too poor.

As a result, Li Yuan was slow in the early stage of development.

However, as long as Li Yuan can persevere, as the level of the Pool of the Underworld increases, these are not problems.

But in general.

Li Yuan was still very satisfied with this fourth-order zombie explosion.

He will definitely use the copper mine blueprint in the future, and the zombie armor is the most needed defensive equipment for the current lord.

As for the last class building blueprint, it should be the highest value of the three items.

But Li Yuan doesn't need it, he has a pool of the underworld, which can recruit different troops, unless you are a high-star class building, and you can also enhance his combat power.

If you have 0 stars, you can only throw it on the trading market.

Li Yuan resurrected the 32 necromancers first, and let them continue to kill zombies along the river, and if they couldn't beat them, they used the method just now to attract the zombies into the territory and attack with the help of arrow towers.

Subsequently, Li Yuancai opened the trading market.

The current market is no better than the previous two days, and there are all kinds of things on it, all kinds of materials, drawings, equipment, and class buildings.

Li Yuan was dazzled when he saw it.

He found the class building blueprints column to see how class buildings were sold.

【Worm Class Building Drawings (0 Stars)】

Price: 1,000 Tier 1 Necromancers, 300 Wood, 200 Stone Ore

【Goblin Class Building Drawings (1 Star)】

Price: 999 second-order death crystals, 999 food units, 999 wood units

……

[Kobold Class Building Drawings (2 Stars)]

Price: 1,999 Tier 3 Death Crystals / 190 Tier 4 Death Crystals / 10 Tier 5 Death Crystals

【Night Cat Lady Class Building Blueprint (2 Stars)】

Price: 2,000 third-order death crystals/300 copper ore

Li Yuan saw that the vast majority of the architectural drawings of the troops on the market were 0 stars and 1 star, and a small number of 2 stars.

As for 3 stars and above, there is no one.

Obviously, no one is willing to sell the architectural drawings of the 3-star and above classes.

Or even if someone sells it, most people can't afford it.

I didn't look at a 2-star architectural blueprint and sold 2,000 high-end third-order death crystals.

Those who can afford this price are at least fourth-level lords.

To be honest, fourth-level lords don't really need 2-star buildings, and their own class buildings should all be above 5-star buildings.

Li Yuan thought about it, set the corpse fly blueprint in his hand at 900 first-order spars, and put them on the trading market.

It is true that the general price of the architectural drawings of the 0-star class is around 1000 spars.

But there's no telling when it's going to sell.

Now time is money, and if he sells it one minute earlier, he will develop one minute ahead of others.
