There are still a lot of things to do in Sarean's schedule that aren't particularly important.

These include a secret meeting with Nefarian and learning how to master the land from Azadas, the guardian of the earth...... Or shaping power, and many Draenor aftermath matters, including the treatment of Ansu, and so on.

However, compared to major events such as the Battle of Ulduar, which may affect the survival of the world, these things can only be regarded as minor problems, and there is no need to rush them for a while.

The death of Anasteria had made Kael'thas realize the importance of his family, and Saljan was also quite touched by this, and he planned to rest for a while and spend time with his family in the territory.

And there are some things that can only be done when you are at home.

Through this local offensive and defensive battle with the trolls of Dhaka, Stella Gossa, Wenlesa and others, who had personally participated in the war, provided some feedback to Sarean on the battlefield.

The impact of hordes of dinosaurs on the battlefield is no joke, and that's just the tip of the iceberg of Zandalara's true combat prowess.

Quel'Thallas now has enough firepower, but lacks a heavy unit like the Dinosaur with the power to propelle on the battlefield.

To this end, Sarayan specifically asked the opinions of barrage netizens and got a brand new concept from them.

Tank.

Because the fertility rate and population problems of Quel'Thalas have never been solved, the consumption of the High Elves on the battlefield is all as small as they can.

If you can use the depletion of resources as an alternative, Sarean will never use human life to heap up, because Quel'Salas can't afford to die.

The Deep Shadow family has long been invested in the R&D and production of the automobile industry, and now it has a certain industrial base and related technical talent reserves.

Barrage netizens believe that it is time to further expand the vehicle industry, and the research and development of transportation vehicles should be changed from civilian to military.

The tank is an important concept proposed by the barrage, and the use of this kind of ground heavy units with both firepower and defense power and infantry can effectively strengthen the battlefield propulsion ability of the High Elves.

"Mounting the Magic Cannon on a vehicle that strengthens its armor defenses......"

After returning to Unicorn City, Salian first visited Stella Gossa who had gone dormant to recuperate from his injuries, and Tina Gossa who was with him.

Since neither Valera nor Onexia have returned, Saljan locks himself in his office to think alone...... In fact, he is discussing the development ideas of tanks and other battlefield vehicles with the barrage.

The battlefield vehicles proposed by the barrage are broadly divided into two categories.

One of them is armored vehicles for transport and high-speed maneuverable combat.

The armor of this type of vehicle is much weaker than that of a tank, but it is more mobile and can move flexibly through all corners of the battlefield.

Armoured vehicles that do not carry any weapons are specially designed to transport supplies and troops, and can also be loaded with different specifications of magic weapons on the armored vehicle as needed, ranging from magic machine guns to magic cannons.

According to the information provided by Kael'thas, while Sarren was busy on the go, the developers of the Weapons Research Institute were not idle, and they had overcome the technical difficulties of the magic guide machine gun.

The advantage of this automatic firearm is that it fires at high speeds and does not require high shooting accuracy, and strives to tilt the stored energy and ammunition in a short period of time, using ferocious firepower to suppress the enemy.

Compared to single-shot rifles, the disadvantages of machine guns are also obvious, the consumption is too large.

Whether it's live ammunition or energy rounds, machine guns with extremely fast rates of fire consume a lot of resources in a short period of time, which dooms them to not reach every soldier like rifles.

If the Magic Machine Gun is mounted on an armored vehicle, it can combine mobility and short-term fire suppression.

If the inflexible Magic Guide Cannon is mounted on an armored vehicle, this heavy armored vehicle can be transformed into a self-propelled gun, which can be shuttled through the battlefield more flexibly to various occasions where artillery support is needed.

Salian was interested in armoured vehicles that could be flexibly matched, but he was more concerned about tanks, which the barrage repeatedly emphasized.

Strictly speaking, tanks are also variants of armored vehicles.

There are three types of vehicles: light, medium, and heavy, and the light tank has relatively thin armor and carries a smaller caliber of magic cannon, which is more powerful than medium and heavy tanks.

Medium tanks are involved between light tanks and heavy tanks, and according to the barrage, medium tanks with both mobility, defense and firepower are the main forces on the battlefield.

The final heavy tank was a true steel monster, trading its mobility for thick armor and lethal large-caliber guns.

However, due to its terrible mobility, it is usually only used in the most important battles.

The world where the barrage is located has a complete set of tank evolution routes, and although the actual development and production still require the craftsmen of Quel'Salas to try and skill, at least it can help Sarren avoid many unnecessary detours.

After talking about tanks, the barrage also mentioned a lot of other war weapons.

Some of them are physical objects that have been verified in their world, and some are fantasy products that are still theoretical.

The world in which the barrage netizens live does not have any supernatural powers, and what is difficult to realize in their world may not be impossible to realize in Azeroth.

Sarren: "Gundam? ”

According to the information provided by the barrage, Sarian drew a large humanoid mechanical structure on the drawings.

"Isn't this an enlarged version of an arcane golem? Does it make sense to make such a big deal? ”

[This is a man's romance!] 】

[Phew!] Even if you think about it, it's not practical to be a human. 】

[The feet are just decorations, and the big people above won't understand! ] 】

[In my opinion, the steel tank is the right evolutionary direction, Gundam?] Dogs don't make them! 】

[Maybe you're right in theory, but Gundam is handsome!] 】

[Handsome is useful! ] Who cares if you are handsome or not on the battlefield, practicality is the most important thing! 】

Amid the barrage of chatter, Sarena drew a prototype of the appearance of the Steel Cannon and the Steel Tank one after another.

"Hmm......" After looking down and pondering for a while, Sarian pointed to the drawing of the steel tank: "Is it really necessary to make the upper body into a human shape?" Isn't it okay to have a direct tank form? ”

[Unlike useless feet, nimble humanoid hands can do many things that tanks can't.] 】

[Kouhu! Why do you say that feet are useless! Don't walk! 】

[Cerebral palsy! We're talking about weapons of war, don't ramble around there! Compared to the all-terrain adapted tracks, the feet are really just decorations! 】

Seeing that the barrage was becoming more and more intense, Sarian smiled wryly and pulled the topic back.

"Gundam or Steel Tank aside, let's talk about the air and space battleships you mentioned earlier."

[I won't be sleepy if you say this! 】

……

Until Valilla returned from Silvermoon City after completing her debriefing with Backlight Blade, Salaen was still sitting alone in her office, writing and drawing thoughtfully.

“…… What is this? ”

Picking up a drawing that Salian had just finished, Valila's mind was full of question marks: "A ship?" And...... Seems to be floating in the sky? ”

"That's right."

Sarren, who had been in a brainstorm meeting with the barrage for several hours, finally stopped and rubbed his brows a little tiredly.

"This is a brand new weapon of war that I came up with on a whim, and I call it an air and space battleship."

"Hmm......" Valera lowered her head and pondered for a moment before speaking, "Referring to the principles of the floating cities of Dalaran and Madroxus, it is not impossible to make the ship fly into the sky, but...... Does this make any sense? ”

"Why do you have to make it in the shape of a ship, isn't it nice to have a floating city that has been proven in practice?"

Salian shook his head: "This involves a matter of fluid mechanics. ”

"The Floating City is just a flashy product, so a large lump of stone bumps is subjected to too much air resistance when flying in the air, and it is not as maneuverable as this streamlined design of the air and space battleship."

"Fluid ...... Mechanics? ”

The noun Salaan said involved Valeera's knowledge blind spot, and she shook her head with a wry smile: "...... Forget it, I'm too lazy to delve into it, you should discuss these issues with the technicians of the weapons research institute. ”

Valeera didn't bother to look through the other drawings on Sarjan's desk, and instead referred to a piece of information that Verreis had told her earlier.

"I don't know if you've heard that Yin Nasi's mother was out of the customs not long ago."

Saljan's train of thought was still on the study of weapons of war, and it took a few seconds for Valeera to come to his senses after his words fell.

“…… Yes? Then why didn't I see her at home? ”

Valera shrugged her shoulders and said, "It's simple, because she left Quel'Thalas in a hurry after walking out of the lab, and she never returned home. ”
