After the war, Ling Yan counted that the entire battlefield was invested in the 3,000 Guardian Mechanical Corps, and it was estimated that more than 700 would be completely scrapped, and more than 300 would need to be re-entered into production for rerepair.

Of course, the gains of this war are not small, it is estimated that 230 steam tanks have been captured, 30 bronze 5.5 Apocalypse tanks, and 1,500 steam heavy soldiers have been recruited.

The heaviest casualties on the battlefield were the miscellaneous soldiers of the large and small noble slave owners, because the Duke of Ria was anxious for victory and ordered the Apocalypse Tanks and Steam Tanks to bomb wildly, even his own people. And the combat strategy of Lu Feng's side is only to lure out the main force, avoid the war, and carry out a surprise decapitation operation.

At the same time, after the annexation of the Steam Slave Country, the population of Noah City suddenly changed from the original 12,000 to more than 107,000 people, a full new 95,000 people, and completely broke the embarrassing situation of pure women in the whole country before Noah City, so that the country of Lu Feng entered the regular and became a normal ecological interstellar kingdom. The Steam Slave Country is not a Bronze Level 4 populous country, which has raised the population base, military labor force and army number of the kingdom of Noah City to a new level.

And the most surprising thing is the data in the King's Tower, the Steam Slave Kingdom has mastered a bronze level 4.5 heavy artillery technology "Primary-Yanlong Heavy Artillery Technology" and a bronze level 4.5 super resistant steel armor technology "Primary-Charlid Super Armor". Moreover, there is a transition from Bronze Level 4 to Bronze Level 5 in the Steam Slave Country, and a large number of Star Source Stones are stored in the King's Tower, totaling as many as 152,000 Star Source Stones!

Up to 152,000 Star Source Stone Reserves!!!!

Lu Feng was completely dumbfounded, and even a little ecstatic, no wonder there were so many interstellar kings in the interstellar exchange who wanted to monopolize the business of the population area. This is the example, a small bronze level 4 war king, through the slave trade, actually stored such a terrifying reserve of star source stones.

Although Lu Feng knew that upgrading from Bronze Level 4 to Bronze Level 5 required a terrifying magnitude of up to 300,000 Star Source Stones, which was a moat and a big bottleneck for a small country, he couldn't help but be stunned when he saw the Star Source Stone reserves made by the Steam Slave Country in order to sprint to Bronze Level 5.

Noah City's original Star Source Stone Reserve was 23,000, and with these 152,000, the Star Source Stone Reserve of the entire Noah City soared to as much as 175,000 all of a sudden.

At the same time, Lu Feng also sold the two pieces of captured king's equipment on the exchange, one was the Duke of Ria's bronze level 4 equipment, which was sold for 1,000 star source stones, and the other was the bronze level 5 equipment of the king of the steam slave country, which was sold for up to 5,000 star source stones.

Sure enough, as Lan Weiwei said, bronze level 5 equipment has become very rare in the interstellar exchange, and the price has naturally risen.

In this way, the total number of Star Source Stones in Noah City has reached 181,000!

But the consumption of Noah City is also very amazing, Lu Feng used 30,000 star source stones to upgrade the King's Tower from bronze level 3 to bronze level 4, and at the same time, he also spent 15,000 star source stones to buy a bronze level 4.5 weapon technology "Primary-Red Devil Laser", and 15,000 star source stones to buy another bronze level 4.5 shield technology "Primary-Black Rock Shield Technology".

These businessmen who buy and sell technology always like to take the names of those "crazy Cooljack hanging and bombing the sky", and Lu Feng and Lan Weiwei are not surprised.

However, the "Beginner-Red Devil Laser" has a first attack bonus, and the effect is still very noticeable when the Guardian focuses on shooting; The "Black Rock Shield" has strong shield endurance and strike resistance, and has miniature self-healing ability, both of which are not bad, and they have been carefully selected by Lan Weiwei.

At the same time, Lu Feng originally wanted to help Ling Yan buy a set of bronze level 6 equipment, but after shopping around the entire exchange with Lan Weiwei, he couldn't buy it. Not to mention bronze level 6 king equipment, even bronze level 5 equipment is difficult to find, and high-level king equipment has become the most sought-after item in the entire interstellar exchange.

Lu Feng also tried to contact the well-informed Zhong Xueqi, hoping to buy a bronze level 6 king equipment from her extensive king connections. However, several messages were sent to the "Battle Nuns Country", but they were all like mud cows into the sea, and there was no news at all, and there was no reply at all. Lu Feng didn't know the interstellar coordinates of the other party's kingdom, and the other party wouldn't tell him, so he couldn't go to see the Battle Nun Kingdom in person.

But Lu Feng was still a little worried in his heart: "The Battle Nun Country, has it been annexed by others?" ”

At the same time, in view of the experience of this beheading operation, or the lesson to the opposing king, Lu Feng suddenly realized a very serious problem, that is:

What if someone did the same thing against Noah?

"We need to buy a King's Tower Defense System!" Lu Feng said at the meeting of the three.

"Entering the realm of bronze level 4 kings, all the novice kings began to have rich experience in kingdom management and combat experience, and they are no longer the stupid recruit kings they used to be, and they have begun to enter the ranks of real players, and they have gone through the examination of war. Like the hidden forces of the primitive tribal country, like the steam slave country being attacked by our air force, now we must also prevent others from carrying out this kind of strategy against us! Therefore, for the sake of safety, we need to purchase a complete set of high-tech defense systems to protect the King Tower of Noah City, so as to ensure that when Ling Yan and I are out on the expedition, the King Tower of Noah City will not be sneak attacked, so that our army will not be distracted on the battlefield ahead, or even be defeated inexplicably! ”

"Your Majesty is right, I am also aware of this problem!" Lan Weiwei opened her mouth and said, "The King's Tower defense system that Your Majesty said is actually sold on the Interstellar Exchange, but the price is generally relatively high, and it can be equipped beyond the level. ”

"Can you skip the equipment?" Lu Feng said curiously.

"Yes, Your Majesty!" Lan Weiwei said, "Just like the king's equipment is the equipment of people, and the war machine is the equipment of the troops, but in fact, in a sense, the king's tower defense system is the 'external equipment' of a country's king's tower, which can be configured beyond the level, but the price is relatively expensive." ”

"Understood, no matter what the price is, Vivi must explore the information, although every time we go out on an expedition, we dispatch the Intelligent Mechanical Legion, leaving most of the human army to guard Noah City, but any country's surprise action is caught off guard, we must leave a back hand in advance!"

"Yes, Your Majesty!"

Two days later, Vivi had good news, a tech merchant happened to have a set of King's Tower defense equipment to sell......
