"Hmm, hmm......." Soon the horn sounded in the dragon village.

Since the last battle, Zhang Jun began to use a new way of commanding, that is, using conch, horn and other materials to make military horns, using different vocalizations and sound lengths to replace information such as assembly, emergency assembly, outing, receiving, resting, eating, and enemy attack.

The sound of the bugle travels farther than the cry of the wyvern, allowing the army to be assembled in a more timely manner to deal with threats, and the reaction time is much shorter.

The sound of the military horn began to echo in the sky above the various dragon villages, and those detachments that were out of the river or resting, or had breeding tasks, heard the sound of the horn, and immediately began to lift weapons, stone bullets, bows and arrows, and the logistics detachment began to enter the warehouse, carrying arrows and stone bullets, and moving in the direction of the position on the other side of the river.

In order to avoid the scorching sun, the reconnaissance team took turns to go into battle, carrying a large amount of water, and some wore hats and quilts made of wicker, and they could not go deep into the desert for too long, because there were few shaded places in the desert to rest, otherwise it would easily cause serious thirst.

As the scouts entered the desert in large numbers, the team began to spot more eagles and eagles in the desert, which was a precursor to the enemy, as these animals did not usually fly around after the sun came out, and it was clear that they were specially trained.

The scout team began to wait for an opportunity to attack the birds, whether they were enemy spies or not, as long as they saw the birds, they would all be killed, and soon the screams of birds were heard in the sky, and the birds were captured or killed by the nimble and skilled fighting dragons.

It didn't take long for a detachment of Wyverns to go deep into the center of the desert and find some concentrated footprints, which were large in scale and covered with large areas of sand, and the detachment promptly notified other Wyverns to come to assist, and then followed the direction of the footprints, slowly approaching the tail of the enemy, and finally found them near several large hills.

The Wyvern Scout began to fly low, trying not to let the enemy spot them, and minimizing the number of Wyverns, allowing only a few Wyverns to reconnoiter over them.

Several wyverns were landing on a sand dune, and then carefully crawled towards the top of the dune, because they had already found the enemy in the sky, and when they climbed to the top, they saw a large group of sword tigers resting between several large sand dunes, and they all brought a lot of ground sloths and giant rats with water bags on their backs, and they also carried a large number of shading tools, some like huge hats, as if woven from thatch, blocked above their heads, forming a small shaded area.

There are also many sword tigers who are drinking water, some are pouring water on their bodies to resist the heat wave, these sword tigers are covered with the space between several sand dunes, the scale is huge, after a rough estimate of a few flying dragons, their number is actually more than a thousand, reaching a staggering fifteen hundred or so, three times more than previously expected.

This time, Neglo sent more than half of the tribe to the Sword Tiger, determined to find the oasis area pointed out in the Black Tiger Flying Pigeon Biography, according to the Black Tiger's prompt, this oasis may be much larger than the Black Tiger in Israel, so Negru would rather abandon his tribe and find the New World and take it for himself.

"Damn, these bastards have come so much, they are about the same number as us, and they are all young and strong sword tigers, and they have brought more than a hundred giant beasts, hurry back and tell the ancestral gods." Several reconnaissance flying dragons saw the large army of sword tigers, densely spread all over the sand, and immediately whispered in surprise.

Then the wyverns began to slowly retreat, flew cautiously, spared a large circle, bypassed the sand dunes, and went back to tell the large army.

After learning the specific location of the enemy, He Meng immediately ordered the Flying Dragon Reconnaissance Team to closely monitor the enemy's movements, and at the same time ordered the Flying Dragon to let go of a few eagles, because at this time, he could not be too alarmed by the snakes, and let the Sword Tiger enter the trap laid by his side.

The sun over the desert is very scorching, which is not conducive to the team's operation, and if those flying dragon bombardment teams carry dozens of kilograms of stones, they have to fly long distances to the central area of the desert to attack the sword tiger, and the body can't stand it at all, so the only way is to let the enemy continue to move forward and enter the area of the oasis before making a move.

He Meng immediately reported the reconnaissance results of the reconnaissance team to Zhang Jun, Zhang Jun was also a little shocked after getting the news, he didn't expect that this time they came more than a thousand people, and when they crossed the desert, they also brought some strange sunshade hat-like objects, although the sword tiger did not know the existence of the flying dragon bombardier and archer, but their hat could inadvertently play a certain role in blocking stone bullets and arrow attacks.

Therefore, this invisibly increased the lethality caused to them by the flying dragon bombardiers and increased the difficulty of annihilating the sword tiger, so Zhang Jun immediately began to discuss with several ancestors whether it was possible to formulate more reasonable attack tactics to maximize the results of the air combat team and reduce the casualties of the ground troops.

On a meadow, Zhang Jun had already ordered his subordinates to pile up a large sand table, which was a terrain sand table he had made according to the experience of his previous life, which contained a very detailed battlefield terrain, according to a certain proportion, with sand, soil and stones, several ancestors gathered around the sand table and began to arrange troops on the sand table.

Zhang Jun is staring at the oasis area close to the desert on the sand table and thinking, the edge of the oasis area is very large, the mountain area only accounts for one-third, if the battle is carried out in the open area, you can only rely on the air force advantage to attack the sword tiger, but those sword tigers are numerous, they can not be wiped out at one time, once they find their weakness, they will definitely look for shelter, or shelter, to avoid the air force's strike, when the time comes, the army must be dispatched to annihilate the enemy, that is bound to pay a heavy price.

The dragon group finally survived a hundred years of peaceful and tranquil development, and only then did the number of races expand tenfold, the scale of two thousand dinosaurs is actually far from strong, just a medium-sized battle, can make the dinosaur clan exterminate, so strictly control the battle casualties, is the primary issue that Zhang Jun needs to consider, and preserving strength is the king.

"No, we can't fight with them, we have to think of a better way." Zhang Jun walked around the sand table several times, always thinking about more reasonable tactics.

Several ancestors were also pointing to the terrain in the sand table and discussing, and the tactic that could be proposed at this time was to line up troops at the edge of the oasis and line up from the front to resist the enemy's attack.

Because it is almost impossible to encircle the enemy like last time, or to detour back to the enemy's tail, because the number of ground troops on your side is only more than half of that of Sword and Tiger, it is difficult to surround them, but it is easy for your own side to be surrounded by them.
