It can be said that Mu Ling's trip back to the Tongtian Empire to bring rescue troops has turned the entire Lingtian Continent upside down! "The Tongtian Empire sent its most elite 150,000 troops to support the elven clan" This bombshell-like news quickly spread to every corner of the continent under the special propaganda of well-intentioned people!

For example, the Hai Clan and the Jin Gao Kingdom, which had received the favor of the Tongtian Empire, sent their own troops at the first time, and the quantity and quality of the troops were left for the time being, and this attitude alone made Prince Jingyun very satisfied! Similarly, he had a "close relationship" with Cao Ke The Sunset Kingdom, after getting the news, formed an expeditionary force, and was personally led by the kingdom's eldest princess Ikawa Luna to aid the Selmir State, on the surface it was to help the elves, in fact, the eldest princess Ikawa just wanted to take this opportunity to look at Cao Ke, and as soon as the war was over, she would pull Cao Ke back to the Sunset Kingdom to get married!

Of course, there are positive ones like the Sea Clan and the Sunset Kingdom, and there are negative ones like the Ericon Kingdom! Maybe it's because of Liu Hongyu, or because there are other secret unknown factors, the Ericon Kingdom and several small kingdoms that have a close relationship with it don't have any expression, not only that, but the Ericon Kingdom also took the initiative to cut off the connection with the Tongtian Empire, looking at that posture, it seems that it doesn't want to wade into this troubled water on the continent of Semeir!

In short, less than a month after the news of rushing to the aid of Selmir Prefecture and fighting against the Dragon Clan was released, the large and small empires, kingdoms, tribes, and ethnic groups on the Lingtian Continent were basically divided into the main battle and the main and two factions. Pen ~ fun ~ pavilion www.biquge.info

Among them, although the Lord and the faction did not advocate directly sending troops, they did not arbitrarily intervene in or condemn the main battle faction in sending troops, and their attitude was relatively mild, and this to a certain extent boosted the fierce fighting spirit and determination of the entire Lingtian Continent to fight against the dragon clan! After the first wave of 150,000 troops in the Tongtian Empire, other forces actually sent a total of nearly 2 million troops to the Semere Prefecture one after another! A great duel between humans, elves, and dragons finally began!

Of course, Cao Ke, who was on the front line in Sémill, did not know all this.

After successfully snatching the three pieces of the Elemental Lord from Naiosretta's hands, Cao Ke secretly returned to Teswar with everyone except the Wood Spirits and his party.

Seeing Cao Ke and Jessica return safely, whether it was Kiki Bai Ju or the generals of the elven army, they all felt that their hearts had always been hanging down! In recent days, the Wind Dragon Clan's attacks on Tesval City have become more and more ferocious and intensive, and Kiki, as the commander-in-chief, really feels that it is difficult to hold on! Now, Cao Ke has returned, and of course the command is handed over to Cao Ke, as long as Cao Ke is there, they will not be defeated! This is almost a natural thought in Kiki's heart, and it is also an almost blind worship and confidence in Kiki's ability in Cao Ke!

And the first thing Cao Ke announced after his return was to let everyone strictly keep their whereabouts secret! The command on the surface is still led by Kiki and Bai Ju, and Cao Ke and Jessica are only hiding behind the scenes to give advice to Kiki and them!

Actually, Cao Ke did this, he also had his own helplessness, and now, he had three fragments of the Elemental Lord on his body at the same time! If this was to let Neosreta know his whereabouts, did everyone think that Neosreta would spare Cao Ke? Of course, the answer was no! After thinking about it again, Cao Ke finally decided that he and Jessica would not show up, as long as Naiosreta could not see Cao Ke, then Naiosreta would not really force the elves to a desperate situation, and there would always be a line left, because the elves were gone, and the things that could tie Cao Ke in the Semeir State would also be gone.

It was precisely because of Naiosretta's way of doing things that Cao Ke decided to hide himself behind the scenes. Anyway, in Cao Ke's opinion, it doesn't make much difference whether he is in front of the stage or behind the scenes! As long as he can lead the army of the elves to resist the arrival of reinforcements from the Lingtian Continent, it can be regarded as a victory!

Next, after inspecting the city defense of Tesval, Cao Ke immediately announced his second decision, which was to mobilize all the forces that the elves could mobilize now and go all out to build a giant crossbow to defend the city!

Before the dragons started the war, the elves didn't even have a city of their own, the elves preferred to live on the canopy of big trees, or in the pure wild forest, they liked and even loved the rich natural atmosphere there, and didn't want to add any traces of human transformation!

It is precisely because of this habit that the elves have a serious lack of experience and knowledge in urban defense warfare! Take the city of Tesval, which Cao Ke and they are now relying on, for example, although the walls are thick enough and high enough, there is not a single weapon on it that can help the army defend! This makes the city wall of Teswar City become an ornament in front of the flying dragons, if it weren't for the fact that every warrior of the elves is born to be an archer, and every time they can rely on a dense rain of arrows to deal with the dragons, Tesval City would have been breached by the dragons!

In order to effectively improve this situation and completely use the walls of Teswar City, Cao Ke thought of a very effective city defense weapon of the Tongtian Empire---- the city defense giant crossbow!

This city-defending giant crossbow is more than eight meters long! It takes four sturdy men to be able to pull the crossbow string at the same time! The crossbow arrows used with this city-defending giant crossbow are more than ten meters long, and the power is huge, and it can be regarded as the most effective defensive weapon against the dragon clan!

If a large number of city-defending crossbows can be installed at the head of Teswar City, then it can effectively limit the attack range of the dragons, as long as the dragons dare to launch an attack, then it only takes a few rounds of salvos of giant crossbows to suppress the momentum of the dragons! In this way, the dragons must break through the walls of Teswar City from the ground, and the defensive effect of the city walls will be vividly reflected!

In order to be able to successfully and quickly complete Cao Ke's second decision, Bai Ju also united several members of the Killing Star who were very familiar with machinery, and everyone was busy with sleepless days and nights, and finally drew the drawings of the giant crossbow defending the city!

The drawings of the city-guarding giant crossbow drawn by them not only inherited all the advantages of the old city-defending giant crossbow, but also combined with the habits of the elves to carry out a series of bold reforms, such as replacing the crossbow arrows fired by the city-defending giant crossbow with the three-thorned moon blade that the elves are more familiar with, and the three-thorned moon blade launched by the city-defending giant crossbow machine is faster and rotates more violently, which is very effective in increasing the attack range and lethality of the city-defending giant crossbow!

For the reform of Bai Ju and others, of course, Cao Ke raised his hands in agreement, the drawings were set, what else did Jessica have to hesitate about? Immediately repair a book, and together with the drawings drawn by Bai Ju and them, the flying pigeon passed the book to the hands of the elf queen.

After the elven queen got the letter and blueprints, she immediately summoned the dwarven craftsmen who had taken refuge in the elven tribe and instructed them to build as many giant crossbows as possible to defend the city as quickly as possible.

These dwarven craftsmen were all destroyed by the dragons, and as soon as they heard that these strange-looking giant crossbows were built to deal with the dragons, they didn't work hard one by one? Soon, one after another, the giant crossbow machines defending the city drove out of this temporary dwarven arsenal and were transported to the front line without interruption!

Seeing that the giant crossbows guarding the city were erected on the city, Cao Ke's heart could finally calm down a little, and then the next step of the work began!

In order to be able to completely block the dragons from the outside of Tesval City, Teswar City must establish a strong logistics support system, and the supply of soldiers, grain, grass, weapons, and so on must keep up with and keep up closely! Out of this consideration, Cao Ke asked Jessica to continue to write letters to the Elven Queen, asking the Elven Queen to temporarily convert three of the four cities immediately behind Tesval City into a grain distribution center. A recruiting office, an arsenal factory, to provide the most powerful support in the battle against Teswar City!

As for the last of the four cities, Cao Ke will not let go, he asked the elf queen to thicken and raise the city's walls as much as possible, equipped with a sufficient number of giant crossbows and three-thorn moon blades, and if possible, build an urn city and a source power shield!

Although Cao Ke's measures will really be quite troublesome and arduous to implement, the elf queen knows that it is all worth it! If she does not make up her mind to follow Cao Ke's advice, her elven clan will most likely be wiped out by the dragon clan! Just like the dwarf and orc clans before! So the queen almost did not raise any objections, and as soon as she received Jessica's letter to her, she immediately assigned the task! The four cities behind Teswar City also began to act intensively while evacuating ordinary people!

It can be said that Cao Ke unconsciously used his own way to transform the characteristics of the elven race! He changed the elven race from a semi-primitive nation that knew nothing about war and could only fight brutally into a warlike and warlike fighting nation! At the same time, he also faintly established a supreme authority among the entire elven race......
