Paving, city building, tuntian, water conservancy affairs, the general's mansion of the Zhu State and the county governments and towns, all have special generals in charge, but the road network in the northwest region, usually with each city as the core, extends to the outside of the city for dozens of miles, hundreds of miles, there is no real sense of the complete gallop system.

However, there are more than 70 counties in the northwest region, and each county has a population of 30 million, 40 million, or even 50 or 60 million, which can be said to be quite a lot in terms of absolute number, but so many people are scattered across a vast land with a radius of more than 10,000 miles, which can be said to be quite vast and sparsely populated.

And the people haunt the prefecture and county, three or four hundred miles away can already be said to be the limit, large-scale elite soldiers and horses mobilization, royal battles and spirit beasts, trekking mountains and rivers are not a problem, not to mention Xuanwu sword cultivation, flying around, in terms of the social status quo of the Great Chong Empire, the demand for galloping can also be said to be really low.

After the three sects established a defensive line in the Demon Deer Ridge, there were five or six hundred thousand soldiers and horses gathered in the Mozhang Ridge, and there was no large-scale human race inhabitation and reproduction around the Demon Deer Ridge, and a large number of grain, grass, ordnance and other materials needed to be transported from the hinterland south of Pingma Mountain.

This thousand-mile galloping road, the Zhuguo General's Mansion requisitioned millions of people and horses before and after, and it took four years to complete.

After the outbreak of the Demon Tribulation, the General of the Pillar State Mansion built an additional gallop road between Ebony City and Demon Deer Ridge, but it also took two years to complete it.

The first batch of borrowed materials from the Yue Kingdom has arrived in Wanghai City, but how to transport them from Wanghai City to Mozhang Ridge is really a headache.

In the past two years, Tianying City and Sanzong have built more than 100 new ships, and the things can be said to be excellent, and they can use twenty or thirty million catties of goods at a time, and travel two or three thousand miles a day, which can be said to be quite convenient, but it is precisely because of convenience and because of the extreme benefits, it has become the primary target of the elite demon soldiers after penetrating in.

In the past two years, the newly built Wind Flame Airships in Tianying City and the Three Sects can only barely make up for the consumption, and they can't add more in a short period of time.

In the future, the amount of material transportation from Wanghai City to Mozhangling is huge, and it cannot be carried by the wind flame airship with high cost and low capacity, so it will need a cheaper way with a larger transportation capacity.

From Wanghai City to the southern foot of Dongdu Mountain, there is a river canal through, you can gather boats and boats to transport materials by waterway, but from Dongdu Mountain to Mozhang Mountain, it is mainly a semi-arid wasteland and grassland, even if there are lakes and rivers, but they rarely connect with each other, and the most convenient and cheap means of transportation is to build a gallop road.

If the construction method before the Zhuguo General's Mansion is used, the galloping road from Dongdu Mountain to Mozhang Ridge will take three or four years to be completed, and it will be difficult to alleviate such an urgent transportation demand.

Moreover, Chen Haizhi Tianying City, after the first battle of Xinyancheng, also governed the Eastern Capital Mansion, and vigorously built the city fortress, Tuntian and road construction inside and outside the Dongdu Mountain, and even large-scale digging of diversion culverts and reservoirs, whether it was the existing craftsmen in his hands, or many special heavenly equipment, so that the Zhuguo General's Mansion wanted to quickly build a gallop road, Chen Hai was the only suitable host candidate.

To tell the truth, the new Chi Road may not need to be repaired between Dongdu Mountain and Demon Deer Ridge, and even this Chi Road is close to the southern edge of the West Black Hair Desert, once a small group of elite demon soldiers cross the Black Hair Desert to attack, there will be a lack of sufficient warning time, but no one is stupid, everyone knows that starting from Mengcheng Mountain in the north of Zhoumi County, building a Chi Road leading to Demon Deer Ridge, why is it not the Wu clan to contribute, but Chen Hai to preside over this matter?

More importantly, Chen Hai has built a passage from south to north and from east to west through Dongdu Mountain.

However, choosing to build a gallop road from Mengcheng Mountain, which is more than 7,000 miles away in the southeast, and only opening the passage in Mengcheng Mountain, which is high and dangerous, will consume a lot of manpower and material resources.

In order to ensure that this life supply line can be opened as soon as possible, Ji Jiangye also provided Chen Hai with all the convenience as much as possible.

Disperse and recruit 500,000 craftsmen and brave craftsmen, I don't know how much time it will take on the road, Ji Jiangye asked Chen Hai to first requisition craftsmen and people from the Eastern Capital Mansion, and then authorized Chen Hai to transfer Zhuangyong from other prefectures and cities in Shaoquan County to make up for the loss of Dongdu Mountain.

And once the large-scale construction of the galloping road is carried out, it will inevitably attract a large number of demon elites to infiltrate and attack, and Ji Jiangye directly handed over the sentry soldiers and horses on the west wing, including 20,000 elite war horses and a war bird battalion composed of thousands of imperial bird sword cultivators, to Chen Hai for control.

Although the 500,000 battalions of city soldiers did not have much combat effectiveness, Ji Jiangye still gave Chen Hai the establishment of ten battalions and city captains, so as to better ensure the operation of the road after completion.

In fact, by this time, whether it was directly leading Beiling Town, or controlling the sentry horses on the western wing, commanding 500,000 battalions of city soldiers, and forming a baggage cart battalion from Dongdu Mountain to Mozhang Ridge in the future, Chen Hai's authority was already much heavier than that of ordinary town guard generals.

From Dongdu Mountain to Mozhang Ridge, close to the southern edge of the Black Hair Desert, there are very few streams and rivers, and there are no big hills and mountains to obstruct it, the geology is hard, Tianying City has accumulated tens of thousands of baggage transport vehicles and other various engineering equipment over the years, and during the construction of the Chi Road, Ji Jiangye transferred Liya Town to Yunmen Sai to garrison, so that Chen Hai would transfer the soldiers and horses of Beiling Town to help and protect the construction of the Chi Road.

Chen Hai mastered so many resources, the actual requisitioned nearly a million men and horses, and the general's heavenly chariot and covered baggage carts were put into the construction of the gallop road, winter and spring, in the half year limited by Ji Jiangye, the gallop road was built, and the standard was slightly higher than the original agreed "first success".

In addition to the Chi Road stretching for thousands of miles, more than 100 miles of walled cities have been built along the Chi Road according to the standard of a thousand miles and a base of 100 miles.

On the one hand, these more than 100 walled cities should protect the Chidao from the attack of the demon elite, and on the other hand, it is necessary to ensure that the Chidao is maintained in a timely manner after it is damaged, and this is also the key to the sub-station transportation system, and it is also convenient to requisition a large number of camels and horses in a short distance to become an important capacity supplement.

When the road was built, the materials transported from Wanghai City and hoarded to Dongdu Mountain had already reached more than one billion catties, but in only two months, all of them were transferred to Mozhang Mountain.

With such a high efficiency and such a low consumption, all the True Monarchs gathered in the Demon Deer Ridge were excited.

The war has continued to this point, and everyone knows very well in their hearts that whether it is materials or people immediately, who can double the consumption of the other side, and reducing the consumption of this side has become the key to victory or defeat on the Western Front.

From Dongdu Mountain to Mozhang Mountain, it is planned to transport 10 billion catties of materials every year, and in the traditional way, it is necessary to requisition one million camels and horses and one million people on the road to complete such a difficult task, but the supply of one million camels and horses and one million people is astronomical.

What's more, such a big target, under the uninterrupted infiltration and attack of a small group of demon elites, even if a large number of elite combat forces are mobilized to protect it, the heavy casualties are shocking.

After all, the intermittent camel horse transport team that stretches for thousands of miles, even if the Demon Deer Ridge can send out all the floating warships and warbird battalions, there is no way to protect them.

In fact, the continuous loss of war on the front line of the Demon Deer Ridge is on the one hand, and the loss of supply and transportation from the defense line of Pingma Mountain to the Demon Deer Ridge is the greater bleeding wound on the body of the three sects in the Northwest Regions, and the losses have been so tragic in the past three years that Zhu Zhenjun's heart aches.

Now the gallop road from Dongdu Mountain to Yantai Pass has been built, although it has also attracted a large number of elite demon soldiers to attack, and the loss of baggage transport vehicles, materials, and people and horses is also a lot, but compared with the tradition, such a large-scale transportation volume, the loss of people and horses, and the consumption of materials have been greatly reduced to less than one-tenth of the previous one.

This change is really impressive, and it has also made many true monarchs see the dawn of victory.

They knew that once the gallop system in the hinterland of the Northwest Regions was built, and more wheeled baggage trucks were used to undertake the transportation of materials within the Northwest Regions, they would have no fear of fighting with the demons.

Therefore, before the completion of the Dongzhang Chi Road, Ji Jiangye and the others realized that the method used by Chen Hai was feasible, so they had already ordered the transformation of the two Chi Roads from Luntai and Ebony to the Demon Deer Ridge, and also asked Chen Hai to be responsible for mobilizing craftsmen and craftsmen in Yantai Pass, and then building a casting workshop for wheeled baggage trucks to increase the supply of wheeled baggage trucks.

Of course, the foundry under the Sanzong Refining Institute also began to cast wheeled baggage carts.

Xingheng Domain does not have a patent right yet, under the eyes and nose of those Heavenly Realm refiners, any Heavenly Machine Weapon made by Tianying City is still at the level of Xuan-level magic weapons at most, and there are no secrets in their hands, and the core problems are mainly focused on cost and easy wear.

At present, the heritage of the three sects is far beyond the reach of the Nine Counties, even if each baggage truck is built, the service life is half shorter, and the casting cost is twice as high, but compared to the traditional mode of transportation, it can be said to be negligible.

On the fifth day of the ninth month of the 35th year of Jianxing, the continuous drizzle has been falling for more than ten days.

Generally speaking, under this kind of weather, the Rakshasa Demon Clan will not launch an offensive, but this time it is quite strange, until the rain falls to the tenth day, the Rakshasa Demon Clan's offensive on the defense line of Yantai Guanzhong North Road and the east flank is still as tragic as ever.

Chen Hai stood under the city tower, paying attention to the changes in the battle on Zhongbei Road and the east flank, and after the completion of the gallop road, in front of the Yunmen Fortress defense line that Beiling Town re-took over, the offensive of the demon clan could really be said to be perfunctory.

In the previous battle, the Xiong Blind Ridge with a radius of several miles and a height of four or five hundred meters was almost flattened, and the demons left more than 400,000 corpses, while Beiling Town died less than 100,000 in battle.

With such a tragic attrition ratio, the demons had to abandon the main direction of attack of Cloud Gate Plug and focus the war of attrition in other directions.

Soon the Rakshasa demon soldiers in front of the Cloud Gate Plug retreated, and Chen Hai was relieved to notice that in the other directions of Yantai Pass, the fighting had gradually subsided.

Seeing that all the city fortresses began to arrange for people and horses to go out of the city to clean up the battlefield, Chen Hai was about to fly to the newly built town guard general's mansion in the inner city, and a green shadow flew from Yantai Pass to this side, which was Ji Jiangye's handbook.

Chen Hai unfolded the edict and said to himself: "At this time, I don't know if there is any military situation to discuss?"

Zhu Tianhe said with an unconcealable tiredness: "The Sect Leader has been paying more and more attention to you recently, but you are still reluctant, so leave it to me first, don't miss the big thing." ”

Chen Hai nodded, and then took Mo Zhai, Ning Chan'er and the others to Yantai Pass.

On other battlefields, the battle was much more tragic than Yunmen Sai, and after the war subsided, there were many things to clean up, so when Chen Hai saw the Yantai Pass to protect the general's mansion, there were only a few people in the main hall, and the guards on the other major battlefields had not yet come......

When Ji Jiangye saw Chen Hai, he beckoned him to come over and sit down, and said, "The demon clan has suffered in front of the Cloud Gate Stopper, and in the last few hard battles, the attack on the Cloud Gate Plug has been quite perfunctory, what do you think about this?"

Chen Hai said with a smile: "That's also because you are the master of the sect and you are here in person......

Listening to Chen Hai's shameless slap on Ji Jiangye's ass, Jiang Jin sat aside, feeling very unhappy, but he also knew that at this time, he could no longer stop Chen Hai from presiding over the western defense line with Yantai Pass as the core......
