"Hoop ......!!"

A whistling sound rolled up a violent wind, blowing all around, and the leaves of the distant trees were swept up by the wind and swirled in the sky.

The whistling sound did not stop, and each sound was accompanied by a light drink, and a shirtless figure appeared in the innermost part like the roar of a dragon and a tiger, holding a large spear far larger than most long guns, the gun was the thickness of a bowl, and it was hard to imagine how he could hold it firmly.

The big gun swings, such as the arm swing, between a smash and a turn, round and free, between a stab and a retraction, lifting weight as light, more than many spear heads are not only suitable for stabbing, but also more suitable for chopping, chopping, splitting, teasing.

The gun was in the man's hand, dancing, faintly, as if a tiger was roaring angrily, and it was soul-stirring.

And he is Zhang Yuan.

"Whew!"

With a breath into a line, Zhang Yuan slowly stopped the movement in his hand, put away the Tiger Roar Wind Gun, and buckled it on the barrel of the Tiger Roar Wind Gun with one hand, although he couldn't catch it all, but he thought that the pattern on the barrel of the Tiger Roar Wind Gun was not much more difficult to use than an ordinary spear, on the contrary, as it became more and more familiar, it would be more helpful to use it.

Come to think of it, just by the size and weight of the Tiger Roar Wind Gun, it can smash a person into internal injuries with a casual blow.

"Time flies so fast, and before I know it, I've been at home for so long! I don't know how Xijuan is doing on the grassland now! Zhang Yuan looked at the blue sky, sweat gradually flowed down, and the whole person seemed to be a little distracted.

More than half a month passed in a hurry, and when Xijuan led an army of 400,000 to leave, Xihe City fell into the most peaceful time, except for the army that constantly transported grain and grass every day, not only did no one harass, no caravans, no grassland tribes, and there were no peeping people.

In the past half a month, Zhang Yuan has not stopped exercising for a moment, and the proficiency of each breakthrough skill has been practiced again, although compared to the increasingly 'perverted' proficiency, it still seems not enough, the experience value has been consumed by nearly half, and there is no successful breakthrough in that skill.

In this half a month, Xihe City did not stop developing, although the war cut off the trade routes here, and the merchants did not dare to take risks, but the caravans of Xihe City itself were always running, on the contrary, because of the truncation of the trade routes, the things of Xihe City in the Western Han Dynasty have become priceless, and under the mutual offset, the transaction volume of Xihe City in this half month has not been affected.

And Zhang Yuan is always paying attention to the situation on the grassland, and he will receive the latest advance every day.

Compared with the wind and clouds, and strive to cultivate internal strength in Xihe City, the grassland can be described as a mess, and there is no place to be calm, the Yuan Dynasty attacked the three major dynasties through the grassland, and the three dynasties naturally will not sit on each other to enter their own dynasty, so the army of the four countries appeared in the grassland, making the grassland of tens of thousands of miles in size, countless grassland tribes are involved.

In half a month, Xijuan's army arrived at the small holy mountain of the grassland, Dolifara.

At this time, the summer to autumn is excessive, and the livestock on the grassland have become fat and strong after the harsh winter and the thin spring.

Along the way, Xijuan continued to send troops to clean up the surrounding grassland tribes, all who surrendered, put away two-thirds of the strong men and livestock and horses to join the army, the rest were sent back to the Western Han Dynasty, unwilling to surrender, either exterminated, the whole clan was exterminated, or migrated early, and when it came to Dolifara, the 400,000 army had reached more than 500,000, the grain and grass did not decrease, but there were many more cattle and sheep, enough for the army to use for nearly three months.

On the other hand, the Yuan Dynasty, which was one step ahead, was only three days away from Dorifara, and its numbers were constantly increasing, from time to time there were tribal warriors or horse thieves roaring from the depths of the grassland on war horses to join the ranks of the Yuan army, and some tribes hurriedly migrated away deep into the grassland, trying to escape the most brutal war in history.

Both sides were accumulating liliang, and it seemed that the Yuan army, which could have arrived at Dorifala in front of them in Xijuan, seemed to be waiting for the other side to camp in Dorifara.

When Zhang Yuan got the latest day's information that Xie Zhongyang had compiled from the intelligence agents who followed Xijuan, Xijuan and the others had already begun to camp in Dolifara.

After seeing all this, Zhang Yuan silently put down the information, walked to the window with his hands behind his back, stared at the blue sky in the distance, but was thinking in his heart, pondering: "Yuanren, it's really this set again, waiting for the opponent to set up camp, and then attacking by himself, which seems to be a loss, but why not unconsciously reduce the opponent's resistance heart, so that they have a little more luck, a little dependence, connect the resistance heart with the camp, and at the same time bind themselves, isn't this a kind of cocoon self-restraint?" When the city wall is broken, the morale drops greatly, and in the rush to kill the past, without giving the other party a chance to breathe, completely crushing the other party, how to chase and slaughter the opponent behind him, but I don't know how Xi Juan will respond? ”

As an agrarian nation, it was originally at a loss in cavalry, even if the Western Han Dynasty was not very short of cavalry now, Xijuan also had a lot of cavalry, but it could not be compared with the Mongols, camping in Xiaoshengshan, with the help of Xiaoshengshan's environmental defense counterattack can not be said to be wrong, and even said to be the most haode choice, but it suffered a loss at the beginning, Zhang Yuan didn't know how Xijuan would win back this game.

In the end, Zhang Yuan called Xie Zhongyang in and instructed him to send a message to the intelligence officers on the front line, regardless of whether Xi Juan saw through it or not, he had to remind him, as for the solution, he believed that Xi Juan, with Xiao He's assistance, could think of a more haode way.

After all the official business was handled, Zhang Yuan came to the Northeast District, because he got the news yesterday that those researchers had finally come up with a practical thing, a multi-crossbow.

Multiple crossbows, also known as repeaters, which have appeared many times in history, such as the rhubarb ginseng crossbow of General Li Guang of the Han Dynasty, the Zhuge crossbow of Zhuge Liang of the Three Kingdoms, etc., is one of them.

In "Expedition", the crossbow is also something that Shili has been working, that is, the musket, and the existence of cannons cannot replace its importance as it does in reality. In this "Expedition", where cold weapons are king, the development of hot weapons is limited, and it cannot be processed and produced on a large scale, the repeater that can kill and injure the enemy on a large scale and fire dozens or even hundreds of crossbow arrows at one time has become an existence similar to a heavy machine gun in reality.

And Xihe City, what was made this time was to disassemble the crossbow sent by the Western Han Dynasty, combined with the crossbow jishu of other dynasties and reality, led by Su Yue, the most difficult of which is not the machine structure, but the material.
