The next policy is to waste energy, the middle strategy is to use energy, the best policy is to understand energy, and the upper policy is to create energy.

It's not a boring noun to build a mountain casually, just say that it is Kunlun-Huaijiang Mountain.

In order to connect the Huaijiang Mountains to the mountain and sea ecology, it must first be determined that it cannot be an active volcano.

Lu Cheng planned to use the first nine years of Kunyu to develop refrigeration technology and create an ice ring on top of the crater to seal the crater activity.

To build a project such as the volcanic ice ring, the pre-card is a large-scale water conservancy project, which brings in a large amount of water resources, and the first phase of the annular water cooling, takes away a lot of heat and delays the eruption.

In the second phase, a giant five-element harmony circle was used to build an ice ring, completely harmonizing water and fire, and letting the volcano calm down and serve itself.

Lu Cheng typed [Zheng Guo] first and drew a blueprint for the desktop.

But when it's time to execute it......

That's a lot of questions.

First of all, Lu Cheng has been completing the construction of mountains and seas with his descendant troops, and he has a full 600,000 high-quality auxiliary legions on hand, applying mountain and sea ecology, cultivation, firearms, and institutionalization, so that the [Beihai Boat Division-Auxiliary Legion] as a whole has reached a very high level, and after joining [Meng Tian], it has long become a flash card auxiliary corps, and its comprehensive engineering ability has been greatly improved, and this unit has always been the backbone of the construction in Lu Cheng's hands.

But this card can't be left in your hand......

In order to deal with the threat of war, they have to provide security for the Kunyu front.

Lu Cheng can only use one of the descendants of the New World [Shanhai Miner Team] and the [Han Supervision Division] and the [Pipa Cave Master] who is still on the table, the former one is sent to dig silver and provide the resource card of [Silver], and the latter one is sent to the New World stability maintenance and strategic flickering missions, as for the Pipa, he is responsible for the United States.......

What are the engineering cards that can work?

【New World Laborers】(Blue 10 Stars)

.......

That's right, that's all there is to it!

The Huaxia people have built a foundation through the times, and the cultivation of truth, spells, and martial arts has been popularized, and ordinary labor cards have these keywords, and the star rating is relatively high.

And the overall population of the fraternal countries is not so strong, and the labor cards recruited are only at this level.

1 point of national power investment, with the manpower of this card, plus the purchased resources, you can only advance the progress of [Zheng Guoqu] by 1% per round!

And the professional part that exceeds the blue 10 stars cannot be dispatched yet.

You can only rely on the drawn [Longship Tribe Boatman (Craftsman God Descendant)] (Gold 1 star).

However, the ally's card [Longship Tribe Boatman] is only at the gold 1 star level.

If you have an engineering card in hand, although it is expensive, it is 10 times more efficient.......

[Five Elements Harmony Circle (Giant)] Not to mention, the two engineering cards don't have the keywords "formation" and "monk", so they can't even start building!

According to Lu Cheng's inaccurate statistics, with the current national strength and resources at hand, it is conservatively estimated that it will take 900 years to complete the [Zheng Guoqu] and the same scale of the Harmony Array, and it will take another 10 years for water cooling to initially cool down the volcano.

Belch......

According to reliable predictions, it is not entirely estimated that the volcano will erupt about 6 times during this period! Furious flames swept across the land, enough to destroy the land area of the Fire Cloud Kingdom six times the size.......

Obviously not.

But improving the quality of the population is a matter of several generations, even if Lu Cheng has the heart to help, he can't do it, and it's good to be able to help the younger brother initially complete self-sufficiency.

Besides, with my current manpower, I'm afraid it will be quite difficult to complete a new, gold-1 star mechanism mine/farmland.

Still running to the moon......

Imagination is beautiful....... Kunlun Mountain Zhong Lingshen show, gather the aura of heaven and earth, take it as the core of the engine, and then build a mythical working quality engine to form a space engine, so that Hanhan has the power to soar.

Step 1...... It's gg to build a canal in the Huaijiang River!

If you don't complete the giant structure in the brother country, use the [ecological stripping] studied in the Buzhou Mountain stage, and pack the [Huaijiang] first and then dispose of it?

It's also not feasible, because [Ecological Stripping] also requires a large number of national power points and high-star engineering cards, which were completed by Xianyang City and the Huaxia population back then, and obviously can't be completed in brother countries.

To solve the current problem, there is only one way, to draw back at least one of your own engineering auxiliary legions!

But in this case, once a war breaks out on the front line, the 80,000 Shanhai Division and nearly 400 forbidden troops will have a negative state of logistical difficulties, and fighting in such a state may fall into an unfavorable situation.

Defend the front or the rear?

.......

In the end, Lu Cheng solved the problem.

That's it....... The front and rear projects are reversed.

The front line does not need to carry out spectacular construction, the auxiliary corps only needs to ensure the logistics supply, the most important thing is the transportation capacity, the Kunyu is so large, a large amount of transportation capacity is needed every day to transport and deploy the resources equipped with domain cards such as [Frozen Soil], [Mountain and Sea Fish Farm], [Tundra], [Youdu Mountain], [Huaguo Mountain], as well as simple farming and grazing.

Lu Cheng once counted that the sub-adult Kunyu can be carried, such as star domain cards, and eight giant construction slots.

(From the structure of the Great Wall in the first phase, there was no increase in slots in the second phase, which should have been, but I forgot to write it earlier...... At the moment, it is not thought to be. ）。

At present, the giant structure has the tail [Rong Ku Power Tail Fin], the left and right [Iron and Steel Wings], the [Great Wall Outer Carapace], the [Right Armor] and the back [Thousand Machine City], and the remaining two slots are reserved for the Aura Shield and the Harmony Array.

As the largest giant structure, Thousand Machines City has evolved for tens of thousands of years, enough to accommodate nine star field cards (artifact Jiuding effect), and all the mountain and sea ecology is around the city.

It can carry more than 5 million units.

It currently accommodates only nearly 700,000 people and 2 million eco-units.

Then, send the Longship Progeny back to help with farming, harvesting, and transportation, they are still capable, so that they can send the auxiliary legion over!

Perfect........!

.......

Kunyu Engineering Auxiliary Corps.

600,000 units.

Dragons and snakes are mixed.

The entries can be said to be bizarre, and the background is also very scary.

The oldest followed Beihai Shuai from the Chinese Millennium War to the era of deterrence.

With the title of God Butcher, there are still more than 100 surviving old craftsmen of the Thousand Machine Family, who have survived by cultivation or semi-organization in the Kun Domain.

Most of the rest survived the Trojan War, the Great War of the Pioneer Era, and the Battle of the Bellmans.

The combat capabilities are equivalent to the long-range flash cards of the equal star, and the engineering capabilities can be seen.

The biggest advantage is...... These veterans who have survived an unknown number of wars have an extremely strong ability to survive and face extreme environments, as long as they are played in the right scene, this engineering card not only consumes less, but also may produce resources.......

In the [Huaijiang] Ecological Volcano, Lu Cheng can maintain such a large engineering corps with 1 point of national strength and 1 point of national strength per round.
