According to the speed of occupation by guild members, in two more days, the four prefectures and thirteen counties between Tianxuan City and Xingxing Gorge will all be occupied by guild members, and at that time, Lin Tianxuan's prestige will rise to an unimaginable height, but at the same time, he will also face an even more dangerous situation.

Originally, he had few people and little power, so he didn't get much attention, and there weren't so many places to defend, and there were few loopholes and weaknesses, and others wanted to attack him, that is, the two places of Xingxing Gorge and Tianxuan City, and these two places were also built by Lin Tianxuan, not to mention impregnable, they were also majestic and powerful, and it would be very difficult to attack them.

But now, for the needs of development, he has brought all the four prefectures and thirteen counties swept by the army of exiles from Heifeng Village under his rule in one go, so he has more flaws and places to defend, and he needs to do his best to connect his forces together to build a more proper defense system until his power is consolidated!

Now the defenses of these cities are very weak, after being sacked by the army of exiles in the Black Wind Village, they are basically in a state of undefense, as long as any army breaks in, it is easy to recapture these cities.

And Lin Tianxuan's current army is only 20,000 people, and they are all in the Star Gorge, unable to effectively reinforce other cities.

So, in addition to capturing these cities, all that is needed is to build as many railroad lines as possible to connect them all!

Since this is the case, it is not only necessary to build a train from one end of Xingxing Gorge, but also to build railway lines from the four prefectures and thirteen counties at the same time, so as to meet Lin Tianxuan's needs as much as possible.

With such heavy thoughts, Lin Tianxuan and Huang Ling'er each stepped onto their mounts and began to fly in the direction of Xingxing Gorge.

Overlooking the earth in mid-air. Beneath the layers of mist is a ruined earth.

In the sky above the four prefectures and thirteen counties, because of the disaster and killing, the evil aura of the earth is very strong, and even some places are scorching the earth and the sky like the flames of hell with teeth and claws, looking at this posture, I am afraid that new ghosts may spawn at any time. But fortunately, basically every city has a god tree, so that the earth evil qi in the city has begun to shrink and consume, and in the future, the earth evil energy will be used to refine the engine and other things, and a large number of them will be consumed, I believe that in the near future, there will be no more lonely souls and wild ghosts in every city.

But even so, the speed of absorbing the evil qi is still too slow, and if the underground evil qi train keeps running back and forth between these cities, it can not only connect all of its own cities in series. I can continue to absorb the evil qi of my own land!

It's so convenient!

With such a thought, two hours passed in a blink of an eye, and Lin Tianxuan and Huang Ling'er's eagle demons also landed in the Star Gorge.

The most eye-catching thing in the Star Gorge is naturally the unparalleled volcanic spiritual well in the world, and from a long distance, you can feel the compelling heat wave and spiritual power paving, which makes people feel excited.

In the volcanic well, there are many earth-shattering gas engines. It was floating and refining in the fiery volcanic spirit pulp, and the amount of it had completely covered the water surface of the volcanic spirit well. Moreover, the thirty-six casting furnaces next to it have never stopped, constantly channeling the magma from the lungs of the earth and casting them into more perfect earth evil gas engines.

It can be seen that in some details, Wu Kai and Dr. Lich still have continuous improvements to the Earth Evil Engine, and the quality of the products is also constantly improving.

It lies in the Grand Canyon of Star Gorge. It was a railway line that had already been built, Lin Tianxuan took Huang Ling'er's hand and walked over with great interest.

"This is the so-called railway?" Huang Ling'er tapped the rails and sleepers with her hand with some curiosity, and said: "It seems to be quite scary, but is it really as powerful as you say? Can you also pull a lot of goods and people?"

"Yes, the railway is such a very affordable and powerful mode of transportation, one of the fundamental constructions of a new era. And now that our territory is getting bigger, there is a growing need for rail transportation to strengthen communication. Lin Tianxuan said leisurely.

The length of Xingxing Gorge is not too long, the distance between Nanguan and Beiguan is only a dozen kilometers at the moment, and the speed of the railway train has also increased to 60 kilometers per hour, and it takes less than half an hour to go back and forth.

"Sniff and eat...... Woo !!! "It didn't take long for the Evil Train to come out in front of them with a thunderous and uncontrollable domineering momentum.

"This is the train?!" Huang Ling'er covered her little mouth and looked at this so-called train in shock!

Now the train is no longer as simple as before, the locomotive of the train has begun to have some shapes, and the power of more than 300 underground evil gas engines is all controlled in a unified manner, gathered in the cab, and turned into some control facilities, so that one person can control all the underground evil gas engines.

At this moment, Wu Kai was standing in the locomotive, while operating the movement of the locomotive, while copying something in his small book, obviously not paying special attention to Lin Tianxuan and Huang Ling'er's storage.

Doctor Lich isn't on the train at the moment, and it looks like he has other work to do.

Behind the locomotive, there were six very crude carriages, all of which were workers, and three of them were empty, and it seemed that they had returned from the construction of the last railway that led directly to Nanguan. It should be the last railroad in the Star Gorge.

Lin Tianxuan took Huang Ling'er and jumped lightly, jumped on the train lightly while the train passed by them, and watched the earth evil gas train come all the way to the two hundred workshops in the Star Gorge, and slowly stopped, and the more than 300 earth evil gas engines all entered the idle state.

"Hmm...... Come, bring the 1st, 9th, 23rd...... The sixty-seven engines were dismantled, and they had reached their rated rate and could be used to make machine tools. Then put on the New Earth Evil Qi engines that were just taken out of the volcanic spirit well, and take them with you. Wu Kai commanded very seriously.

Immediately, some workers unloaded all the sixty-seven earth brake gas engines and installed new earth brake gas engines, although the overall power was a little lower, but on the whole it did not have much impact.

"Okay, now load the newly cast and sharpened muskets and mortars into the car, and let's send them to General Huang!" Wu Kai said with a serious face.

The workers, apparently trained, were very numb in their hands and feet, and lifted their mortars and muskets directly from the ground and loaded them onto the train. There are a lot of them, I'm afraid there are at least a few hundred.

Looking at the workshop, fifty lathes are roaring hard, each of which is driven by a shaky engine, and is producing muskets and mortars in an industrial way......!
