In the next three days, Xu Yin and a group of generals were there to study how to train this new ironclad water rhino army, and Du Long did not interfere for the time being, but watched carefully.

Although he didn't interfere in General Xu Yin's training, he also discussed with the Ring Spirit Beauty in his heart how to improve the combat effectiveness of the Iron Armored Water Rhino as much as possible!

For example, add leather armor to these iron armor water rhinos, add black dark iron eye patches, add a layer of black black black iron soft armor under the relatively soft belly, and so on!

There is also a set of heavy armor made of black black iron as the main material for all ironclad water rhino soldiers, and each ironclad water rhino soldier must also be equipped with ten black black iron javelins, heavy assault guns and other far and near offensive and defensive equipment!

In short, Du Long and the Ring Spirit Beauty first thought of a way in terms of equipment, ready to give full play to the combat power of the heavy demon beast army like the Iron Armored Water Rhino, and arm each Iron Armored Water Rhinoceros Cavalry to the teeth, so that I can hurt you as much as possible, but you can't hurt me!

In addition, Du Long also took the time to find a boulder from the Demon Beast Forest in the distance and placed it in the middle of the Iron Armor Water Rhino Military Camp, which was engraved with a set of cultivation exercises from the Yun Qi level to the Gangdan level, for all the soldiers of the Xiao Cavalry Legion to learn at will!

In this regard, the soldiers of the thousands of Xiao Cavalry Legion were all very excited, and they were able to cultivate all the way to the Gangdan level, which was only owned by some big families, where could they allow ordinary people like themselves to cultivate!

Ordinary people can usually only come into contact with some low-level exercises, and it is good to be able to reach the cyclone level after cultivating for a lifetime!

Three days passed quickly, although Du Long was still not satisfied with the training method of the Iron Armor Water Rhino Legion, but he didn't say anything, before the equipment came down, a lot of training was only adaptive, and after the equipment came down in the future, targeted intensive training would be carried out!

Early in the morning of the fourth day, Du Long continued to set off with another 2,000 men and horses, as the chief general of the Xiao Cavalry Legion, Xu Yin naturally wanted to continue to advance, and half of the generals left in the camp of the Iron Armored Water Rhino Army, including the newly joined Iron Bull!

This guy couldn't walk as soon as he saw the ironclad water rhinoceros, and his tower-like size was finally recognized by the ironclad water rhinoceros king Ben Long, and this kid was lucky to become the knight of the ironclad water rhino king!

Now that he has become a member of the Iron Armored Water Rhino Army, he can only stay!

With two thousand men and horses, Du Long and the others naturally couldn't walk on foot, but requisitioned all the iron-armored water rhinos in Benlei's territory, not for conquest, but for transporting soldiers and horses to pass through the demon beast swamp, these iron-armored water rhinoceros old and young people can also do it, and there is not much risk!

Through this experience, Du Long had an idea in his heart, in the future, his subordinates would have to travel back and forth through the demon beast swamp to transport supplies and personnel, and then they could requisition these old and young people of the Iron Armor Water Rhino.

After crossing most of the Demon Beast Swamp, the group arrived at the edge of the Inner Domain of the Demon Beast Forest after five days, which was close to Xiao Lie's territory, and under its leadership, the army soon came to its territory and joined the Flame Tiger King Rooney, who had been waiting for a long time!

Next to the huge lake, thousands of flame tigers were lying there in groups to rest, although that scene was expected, Xu Yin and the other soldiers of the Xiao Cavalry Army were still shocked by the scene in front of them.

"Rooney, come, let me introduce to you! This is Xu Yin, the commander of the Xiao Cavalry Legion, if I am not here in the future, you will have to obey his deployment! And this is the Iron Armored Water Rhino King Ben Lei!" Du Long enthusiastically introduced: "This is the Flame Tiger King Rooney I told you about a long time ago, reaching the early strength of the fourth order!"

The scene of several humans and beasts knowing each other is a bit funny, Ben Lei and Rooney can communicate with each other in beast language, but Xu Yin can only stare at it, he can't understand the beast language at all, so Du Long can only temporarily translate it in the middle.

"Husband, people have wanted to ask for a long time, how do you understand the language of beasts?!" Princess Huofeng on the side took advantage of a certain chat break and pulled Du Long to ask in a low voice.

"Hehe!" Du Long replied with a sly smile: "Don't you know that your husband is a genius?!!Is there anything else I don't understand in this world?!"

"Nasty! fool people......" Huo Feng glanced at him with disgust, obviously not believing his nonsense......

The establishment of the Flame Tiger Legion was also very smooth, with only two thousand human soldiers, but there were six or seven thousand Flame Tigers, which was really a small number of people, and those Flame Tigers who were first selected by human soldiers were very happy.

For the convenience of command, General Xu Yin naturally became the knight of the Flame Tiger King Rooney, one is the intermediate level of the Gangdan rank, and the other is the fourth order primary, and the strength between the two is not much different, and Rooney is also willing to combine with the main general of the Xiao Cavalry Legion.

The ensuing adaptation training was nothing to explain, and Du Long also talked to the Ring Spirit Beauty about the equipment of the Flame Tiger Legion, and both of them put forward some of their own opinions.

Finally, the future development direction of the Flame Tiger Legion was determined, and the Flame Tiger should give full play to its advantage in speed, so it should not be equipped with heavy equipment like the Iron Armored Water Rhino Legion, which would limit its combat effectiveness.

In order to pursue concealment, Du Long asked the Flame Tiger Legion not to camp directly in the open air like the Iron Armored Water Rhino Legion, but to live in caves that extend in all directions.

On weekdays, I only come out when I come out to train during the day, and in order to keep it secret, I deliberately chose a relatively remote valley, so that the opportunities for exposure are relatively small.

After staying here for another three days, Du Long finally decided to leave here, in addition to continuing to arrange people to join the Flame Tiger Legion here, he also had to start arranging the targeted production of weapons and equipment!

Xu Yin originally wanted to stay and train the Flame Legion, but was vetoed by Du Long, who asked him to hand over the training plan to his generals to carry out, and then go back with him.

As a chief general, Xu Yin must coordinate the overall situation, fully consider the training and logistics support of the two demon beast legions, and must know Du Long's positioning for the future development direction of the two demon beast legions.

So, Xu Yin led dozens of flame tigers, as well as the iron-armored water rhinoceros that had transported supplies before, and Du Long took the two beauties to ride Xiao Lie first, and he didn't have time to continue to follow those slow-moving iron-armored water rhinos to waste time there.

In only half a day, Du Long rushed back to the camp of the Iron Armored Water Rhino Army, and asked Tie Niu to arrange for an Iron Armored Water Rhino Cavalry to report back to Heixuan Iron Mountain, and he rushed back non-stop!

At the secret military base of Black Xuantie Mountain, Du Long ignored the dust and dust all the way, and went directly to the secret weapons factory cave to find Ou Yezi who was busy in the dark.

"Brother Du Long, you came back just in time! Come and see something good with my brother!" As soon as Ou Yezi saw Du Long, he immediately excitedly pulled him towards a certain heavily guarded cave on the side.

Putting down the words for the time being, Du Long followed Ou Yezi curiously, and went to see what good things he was so eager to show himself.

In the empty cave, Ou Yezi took Du Long to the only item in the cave, and on a stone platform, a strangely shaped crossbow arrow was randomly placed.

As a son-in-law with a military background, Du Long has seen many ordinary crossbow arrows, but he has never seen this kind of strange guy, the crossbow body is similar to other crossbows, only with an extra beautifully shaped cylinder!

On top of the cylinder, there is a lever and an aiming standard!

"Huh, what a strange crossbow arrow!" Du Long said lightly.

"It's very strange, and it's very practical!" Ou Yezi smiled: "The first weapon construction diagram you showed me last time, and this is what you produced! It is also the first finished product that my brother has worked hard for many days!"

"Hehe, Brother Ou Yezi, can you introduce it to the younger brother, how is this thing a practical method?!" Du Long smiled lightly.

"No problem! Look at me!" Ou Yezi was not polite, and directly picked up the crossbow arrow, which was only two feet long, and then pulled the trigger on the wall of the cave on the side.

Bang!

With the light sound of the bowstring, a black light shot out from the cylinder of the crossbow arrow, and instantly shot on the hard black iron ore wall, a crossbow arrow that was one foot five long and only a small tail trembling there.

"Good fellow! It's really powerful!" Du Long couldn't help but sigh lightly.

"The power is not small, if it is just these, then it is no different from an ordinary crossbow!" Ou Yezi couldn't help but touch the mustache and smiled triumphantly.

"Oh?!!, what do you mean by that?!," Du Long wondered.

"Hey, hey, little brother, you're watching!" As soon as Ou Yezi's voice fell, he pulled the lever on the crossbow arrow cylinder one after another, and then pulled the trigger, and black light shot out of this crossbow barrel desperately, constantly shooting on the hard cave wall!

"Oh my God......! This guy can still shoot in bursts, and he doesn't need to fill the crossbow bolts again and again?!" Du Long finally saw the magic of this crossbow arrow, good guy, it can actually be fired in bursts, and every time it shoots out is an incomparably sharp and hard black black iron crossbow arrow, the power is really amazing!
