From the point of view of defense parameters, Shanhaiguan is a well-deserved fortress of the mythical era.

But it doesn't stop there, it also has three five-element engines left to power it.

One that satisfies the daily plugging and unplugging power supply needs of the cards on it to prevent them from being surrounded.

There are still two seats left that can be heaped out

One is used for energy to the ground, and the other is for the air.

The small-caliber Jiao cannon was once equipped with Bishui Pass, but the effect was not good, and it has long been eliminated.

Lu Cheng planned to use a larger-caliber dragon cannon to suppress the ground remotely and reduce the number of incoming enemy troops.

As we all know, the dragon is incarnated, built with the Dragon Palace, Yunmengze and a wide variety, can fly good at melee combat, semi-organized into the sky as a feather forest army fighting mount.

Behemoths that are not suitable for modification into flying mounts will be more likely to be kept in fortresses. They can be used to repair fort walls with rock materials, and they can also be used as fortress cannons, throwing deadly earth-shaped spell artillery bombardments at enemy troops.

Since there is no bond between the earth dragons and the combination of the main guns like the Sanxiao sisters, Shanhaiguan is expected to install three single-shot earth dragon cannons.

But the dragon is not Jiao.

Its growth is measured in thousands of years and 10,000 years.

With Yunmeng and Dragon Palace, it is easy to transform a young dragon, but it will take a hundred years for a young dragon to grow to a body diameter of hundreds of meters, and it also needs to be armed and trained in combat.

"Time" ≈ immortal energy, and top-level resources are a huge amount of money.

At least in the current era, Lu Cheng, a celestial immortal, can't mass-produce an adult dragon.

During the construction of Shanhai, the Dragon Palace only produced a loli cannon with a dragon body diameter of 203m.

But the firepower has definitely surpassed the 32 510m Xuanjiao Bianshui Pass

There are a lot of secondary guns

There are ten movable firepower platforms on each side of Shanhaiguan, and there is also a Shenlei airfield in the south for the Yulin Army to take off and land.

Each firepower platform is equipped with a large Dharma Tower and a sword array, which can accommodate 10,000 sword cultivation units and 30,000 magic cultivators at the same time, reaching the highest level in history.

Moreover, in order to expand the capacity of flying swords that can be lifted into the air at the same time, Lu Cheng built a whole five stargazing platforms in the center of the east, west, south and north (only one of the previous pass level was owned by Yanmen, which was destroyed by the angel air attack), all equipped with armillary rangefinders, and the number of flying swords that can be lifted into the air at the same time is five times that of Yanmen Pass!

If the Colossian Angel Legion is still there, and the air raid on Shanhaiguan, it will be hung and ignited by the Nine Dragons Divine Fire Cover, as long as it is discovered by the armillary sphere, the torrent of flying swords will directly drown them.

With this kind of armament, the [Shanhaiguan] fortress-level energy supply still has a surplus for maneuvering.

A surplus energy supply is a must, because Shanhaiguan is designed to be airdropped to the enemy front and hold a large amount of firepower.

After being transported airborne by Taihang Mountain, it is very important to be able to fly slowly on the surface.

However, it cannot be moved now, because the construction has not yet been completed, and the pass-through life support system has not yet been established, if the equipment is complete, Bai Qi will not choose to train here.

Su Dingfang's 6,000 Shanhai Fortress infantry were specially trained as Chengguan bunker combat troops, which were used to defend Shanhaiguan in the harshest and most unbelievable environment.

As for what kind of environment it is, it is unbelievable.

Su Dingfang thought for a while.

"For example, suddenly being thrown into the enemy's encirclement, the mantle is loosening, we are still sinking, and there is extreme heat around us. Gas? ”

"Is it because of the brains of those gentlemen in this palace that we are in this situation?" One of the sergeants still had something stuffed in his mouth, slurred.

In the last generation, the main food of the army, the meat was still cured dangkang meat, henggong fish, and the dishes had some improvements, but also laurel.

After Yunmengze was laid out with five-color soil, the output was greatly enriched.

The steamed emerald harrier in front of him has tender meat, sweet and fragrant entrance, and there is a taste of marshland spirit grass in the aftertaste.

Today's lunch staple food also has steamed buns, laurel filling, and dangkang meat filling.

These dishes were flown in from Chang'an, they were full of energy and taste, and after they arrived, they were steamed out using the high-temperature spirit steam of the steam mechanism in the center of the fortress.

Lu Cheng's ideal of giving soldiers a hot meal with surplus energy at any time during the Millennium War was finally initially realized in the era of ascension.

The food of ordinary mountain and sea soldiers is already rich enough.

But the food provided to the aura troops in the barracks of the various fortress sects was still almost meaningless.

The Shanhai Organizers are mainly used to combat with infantry combat traps, and the demand for pure energy is not high.

And the cultivator army that cooperates with the organs is not so easy to deal with

Bigu, it's just that it is impossible not to eat grains and grains, and it is impossible not to consume energy, and the immortal family still has to hold a banquet and refine the elixir.

The medicine furnace that provided logistics for the military monks did not usher in a full replacement.

Although theoretically, the efficiency of the Spirit Steaming Danding is much higher than that of the previous Five Elements Fire Gate Ding, but due to this era, the Spirit Steaming technology is far from being completed, and it cannot be miniaturized.

Therefore, the small Lingzheng Danding only exists in theory.

As for why not build a giant Danding

Lu Cheng has so much aura to burn, and he doesn't have so many medicinal materials to sacrifice!

You can only fill a small half pot at a time, isn't that a waste?

However, the fact that Lingzheng Danding has not been developed does not mean that the sect military camp has not improved its food.

Lu Chenglao has assisted the logistician, and he still has a way.

At present, Yunmengze is producing a large number of spirit beasts and wild plant products.

Meat and vegetables can be used for military use, people's livelihood can be eaten, and animal materials can be used for industry, but the crystal elements and the like can be supplied to the sect.

However, as we all know, eating raw crystals, absorbing mixed heaven and earth aura, and directly absorbing untreated impurities and aura from the raw ore of spirit stone are all behaviors that are absolutely not recommended.

will be added to the "Gone Crazy" status unless you are sure that you are the protagonist of a book.

Lingzheng Danding is still on the technology tree, indicating that the "refining" technology has not yet been pointed out.

However, the spirit distillation purification and high temperature and high pressure purification technology have entered the experimental stage.

Since there is such a surplus in the energy supply of Shanhaiguan, then directly use the high temperature and high spiritual energy pressure of some spiritual steaming mechanism arrays to purify raw materials and produce high-grade spirit stones, spiritual blood essences, and bright crystals, maybe it can relieve the supply pressure of a large number of front-line sects?
