The Twelve Goldens are the same as the Arcane Tower of the Crown of Secrets, each requires a separate **** level, and the upgrade conditions are also different.

Now the four golden figures are all first-order.

In order to advance to the second rank, in addition to 50,000 soul crystals, each golden statue also needs matching special materials.

Note that it is a special material, not a special building material!

The upgrade of the Twelve Golden People is no longer limited to whether or not to apply special building materials.

However, correspondingly, new restrictions have also appeared on the special materials required for upgrades of different numbers of golden people.

The "ugly" golden man needs special materials that fit the power of his own soil.

The "Noon" golden man needs special materials that fit the power of Ding Huo.

"You" Jin people need special materials that fit the power of Xin Jin.

The "Xu" golden man needs special materials that fit the power of Wutu.

The pattern is obvious. Obviously, there are eight remaining golden statues that have not yet been built, and the upgrade requirements are not much different from these four golden statues.

This means that you want to fully upgrade the level of the twelve golden people.

Huang Yu needs to prepare twelve kinds of special materials to meet the upgrade requirements of the twelve golden people.

Huang Yu has special materials that fit the "power of the earth".

That's right, it's Kun Jinyan!

This is the world's territory, currently the largest amount of special building materials.

Not surprisingly, the Kunjinyan City Wall will become a common city wall in the universe in the future.

Now take out 200 units to upgrade the "ugly" golden man, and it will not cause much impact.

The special materials required for the upgrade of the "Noon" golden man need to fit the "power of fire".

Huang Yu made a special search.

It was found that the magic flame sand, which brings the architectural characteristics of "Soul Eater Feast" to Tiger and Leopard Riders, is a special material that is extremely close to the power of Ding Huo.

And the grade is very high, and when used on the "Wu" golden man, it will exert its strength to the extreme.

However, Huang Yu was able to buy only 200 units of magic flame sand at that time, and now all of them have been put into the upgrade of the tiger and leopard cavalry camp.

In addition to the magic flame sand, among the existing materials in Huang Yu's territory, only the fire essence is slightly touched.

The Fire Essence is closer to the power of Binghuo of the "Si" golden man, and does not meet the upgrade requirements of the "Wu" golden man.

Later, Huang Yu searched the Chaos Mall and found a rare grade material called Burning Spirit Stone, which was more suitable for the "Power of Ding Huo".

To this end, Huang Yu paid more than 80,000 soul crystals, bought a burning spirit stone mine, and placed it in Zhanyi City.

After mining 200 units of the Burning Spirit Stone, you are going to upgrade the "Noon" Golden Man to a second-tier building.

The mineral resources that are close to Xin Jinzhi's power were also owned by Huang Yu.

It was the glazed gold that brought the "Breath of the Sun" architectural feature to the Imperial Guard Camp. It was a perfect grade material similar to glass.

It's a pity that Huang Yu still has no stock in his hands. All the glazed gold was used by him to upgrade the Imperial Guard Camp.

Huang Yu looked at the existing materials.

Among the many mineral resources in the territory, the rare grades of purple gold and yellow gold stone can barely be used.

However, the grade is the same as the burning spirit stone, which is a rare grade, and it is not a material that is completely close to the power of Xinjin.

In order to get more suitable materials, Huang Yu has to search more.

What Huang Yu did not expect the most was that the ether heavy oil was a special material that was more suitable for the power of the earth!

Since Huang Yu established the ether heavy oil well, the Magic Pattern Research Institute has extended many projects.

Even some of Huang Yu's ideas of using Bluestar Technology in the past have gradually sprung up.

At first glance, the ether heavy oil is just pitch-black, a viscous liquid that contains messy but rich energy.

But as long as it is handled properly, materials of various grades and properties can be obtained.

Now the ether heavy oil has another use.

Twelve golden figures, not to mention the upgrade of the grade, just to upgrade the grade, make Huang Yu feel a little bald.

To upgrade all the twelve golden people to Tier 3, in addition to a large number of special materials, without a few million soul crystals, there is a high probability that they will not be able to come down.

Moreover, the strategic significance of the twelve golden people is quite special, and even because of the existence of the "You" golden people, fighting methods such as "I will form the head" can be developed.

It is impossible to disperse for a long time and be stationed around.

When Zhanyi City is completely stabilized, the four golden figures of Ugly Wuyouxu will still return to Huanyu City.

Because of its potential to upgrade its rank, Huang Yu intends to pay the price to make it a strategic weapon in the world territory.

Considering that upgrading the Twelve Golden People is not a one-day effort.

Huang Yu resisted the urge to collect all twelve kinds of materials, and opened the panels of the Youni Army Barracks, Qingchuan Barracks and Thoron Giant Eagle's Nest respectively.

Pay the Soul Crystal and choose to upgrade it to Tier 4.

This is his main task today.

Excellent-grade arms buildings, not only do not need special building materials to upgrade to the fourth rank.

Compared with the extraordinary arms buildings, even the upgrade time is reduced by more than half.

Huang Yu felt that when he returned to Universal City later, he would be able to receive information prompts for these three excellent-grade buildings.

At that time, Huang Yu still needs to pay a lot of soul crystals to carry out the largest explosion in the history of the universe!

However, looking at the few soul crystals left in the account, it was difficult for Huang Yu to show joy on his face.

During the time when Zhanyi City was established, the soul crystal flower was too fast.

"Would you like to send troops to attack and occupy several alien territories?"

"Or sell the tide of the Styx cheaply?"

"Why did the idea that Lord Kashde did not complete the contract and work for himself for a lifetime..."

Huang Yu supported his forehead and thought seriously.

"Not enough soul crystals, just earn more."

"However, the development of the world territory cannot be routinely relied on discounted artifacts.

"The ecology of the world must be improved as soon as possible."

"Pharmaceutical materials, mineral resources, special buildings, and even materials, equipment, and pharmaceuticals in the territory."

"I can't just rely on me to buy it with a discounted artifact."

Huang Yu knew.

The development of Universal City is indeed very fast.

But the speed is fast, and some details that are difficult to notice will be ignored.

The current Universal Territory ~www.mtlnovel.com~ is more like being forcibly fed by Huang Yu into a fat man. It suddenly looks rich, but it is actually very bloated.

There is an upstart feeling.

In the mountain tomb, the battle begins.

Edward sneezed, and after feeling nothing out of the ordinary, he rubbed his nose and stared at the battlefield below.

After arriving at the halfling territory, Edward did not say a word of nonsense, and immediately ordered his soldiers to attack.

He did pick the right time.

The angel who often floated behind the church, rarely fell to the ground after a night of beast swarms.

The head bound by the ring chain had its eyes closed, and the deformed limbs and wings behind it were very weak.

Obviously, to maintain the protection of the Holy Light overnight, the angels have consumed a lot of faith.

However, this does not mean that angels cannot play any role.
