"70 kilometers, although it can directly reach a depth that may not be reached in two months, can be a real train to hell. Along the way, there are too many factors that can lead to the final accident, and there is too little and too little that can be done by manpower in a short period of time. Luo Ling thought about pacing back and forth, now was the time to pick between adventure and responsibility.

"Go to the underground camp and make every effort to make armored boat guide rails." Luo Ling chose responsibility and kept the risk to himself.

"Get out of camp! Get out of the camp, move fast! The order was quickly passed to the end of the line.

People got down from the seats of the armored boat one after another, and there was a special dwarven mechanic holding a magic guide, and between the buckle between the armored boat and the armored boat, the magic light flashed and clicked! Click! The bolt bounced, the armored boats were disengaged from each other, 144 armored boats, that is, 144 camp tents, in the narrow passage, the armored boats were like loose joints to pull away from each other, and they were rooted on the spot, the tentacles of the mask were nailed down one by one, and the device was activated, and the translucent magic energy mask took the main launcher supported on the armored boat as the core, connecting the tentacles to form a skeleton, and then the mask was formed.

The reticles are tightly connected, but isolated from each other, so that even if something goes wrong, it's just an area and doesn't spread to the whole field. Under normal circumstances, there is no special order, and the slaves are not allowed to move back and forth, only those who need work are transferred to the specially hypothetical temporary workshop in whole columns.

Each time the line is unfolded or retracted, it takes about 90 minutes. With the mastery of the slaves and the rationalization and streamlining of the process, this time is still shortening, but at least it will not be less than 1 hour, and the speed of such a camp is already very, very fast.

The guide rail was determined by Luo Ling and added to the system at the beginning of the development of the armored boat, it is also called the magic track, which is not closely connected one by one, but laid out section by section, mainly to deal with various ramps of more than 1 kilometer, after all, the naturally formed canyon is not straighter than the artificially dug one, and without the guide rail, it is difficult for the armored boat to move extremely fast in the long ramp.

The maximum spacing of the guide rail is 100 meters, 70 kilometers, at least 700 guide rails are needed, in the curve area, a guide rail is needed to adjust, you can shorten the distance and set more, plus laying, even if it is a multi-area laying at the same time, I am afraid it will take 5-7 days to complete. And that's just through the canyon, the lava lake below is a different story.

"Take the Flame Flower and come with me." Luo Ling ordered Gregory, Mycium, Darren, Ibek, Orbuk and several others, got on an armored boat, was pulled backwards by a tractor, and entered the canyon.

It wasn't a thrilling trip, in fact, it was only 30 mph at a speed of 30 mph under the force of the tractor. This time, Luo Ling not only stepped on the road himself, but also had the meaning of removing obstacles, and when he encountered huge rock obstacles along the way, Luo Ling would directly shatter them with engineering magic. He is filled with fire element energy, which has a melting effect while bombarding, and can try to ensure that there is no sharp bulge of ground thorns in the place where it has been bombed, and the armored boat is most afraid of ground spears and ground thorns, especially at high speed, that thing can be as sharp as a cutting knife, and once it destroys the magic array system at the bottom of the armored boat, the consequences are unimaginable.

Just like that, while walking, while flat, sometimes when encountering a particularly large one, you have to come down and deal with it carefully, 70 kilometers, it took more than 1 hour to complete.

Luo Ling's heart was a little more stable. "The slope is big, but the road conditions are not perverted, unlike the water slides in the amusement park, which are spiral and large arcs...... Water slides! Luo Ling suddenly realized that maybe the boat could resist the water, but this plan quickly made him negate, the inclination was too large, and the water would fall like a waterfall, and it would not be possible to resist the water at all.

At the end of the canyon, there is not a direct lava lake, but a shore of more than 300 meters. But this little distance is not enough for the armored boat coming down at high speed to brake the car, and it can't brake, and there is a lava lake in front of it to cross. It is said to be a lake, but the area is so wide that it is all lava as far as the eye can see, except for the black border that can be faintly seen at the end of the line of sight ahead.

Due to the poor ventilation, this is simply a furnace world, the poisonous smoke is golden under the reflection of the lava, in the lava lake, the blackened scum is only such a thin layer, and the coverage is a small piece, a small piece, more places are bright red and incandescent white magma tumbling and bubbling in the lake, and from time to time there is a lava bag that spews up, arcing back to the magma, or simply goes straight up to the dome, bursting into scattered flowing fires and falling.

Luo Ling asked him to go down to the bottom of the lava lake to probe, and he himself used engineering magic to mine the rocks at the end of the canyon, the process was not complicated, and the fire element energy was used to form a powerful molten cutting ray to cut the stones. Although it didn't have to be square, Luo Ling instinctively cut it into a big piece of the rules. Then he threw it to the right position of the canyon, and each boulder weighing more than 2 tons was like an empty big wooden shell in his hand, and he sent it lightly, and the position of the throwing was extremely accurate, and it didn't take long for a long platform to be erected.

After completing the sprint of the canyon, the armored car queue needs a sufficient arc to change from a 50-degree inclination angle to a horizontal advance, and what Luo Ling is doing now is to erect such an arc, and the bearing capacity of the lane stacked with rocks is not much to worry about by the fusion method of crystal technology.

Orbuk and they also wanted to help, but they were not at the same level as Luo Ling, and they couldn't help but add to the chaos, but fortunately, they could do some other things, such as calculating how much speed it would take to fly over this lava lake, and at this speed, what should be the arc at the end of the canyon, etc.

To Luo Ling's delight, after popping the probe, he said that the location of the center of this lake is not on the road of the driveway, but on the side near a rock wall, so there is a bottom base that can be used under the lava lake, but it is more than 60 meters deep.

If you can build a bridge over the magma, the armored boat will not need to be too fast, so there will be no need for a guide rail or something, just add a few more traction heads to ensure that the boat team does not stall.

"My lord, I know that with your ability, it is entirely possible to build a bridge pillar in it, but I suggest that you take another approach, like the one commonly used by the extraterrestrial creatures of my homeland, to build a planktonic plate on the lava, as long as it is large enough, the buoyancy is still guaranteed."

"No, I have a better way." Luo Ling pointed to the dome above the lava lake, which was about two hundred meters high. "With the right arc and enough speed, we can rush up to this dome and build a tunnel there that will save a lot of time and effort than in a lava lake, and it can be used later."

Obuk and others praised this idea as good, saying that Luo Ling knew how to use this three-dimensional space better than the natives of the dark region, in fact, this was just a 70-kilometer slide that made Luo Ling think of a roller coaster, since he could go down a big slope, it was naturally no problem to climb a small slope.

Construction work commenced. The cruel environment here restricts the work efficiency of ordinary people, and in order to hurry, Luo Ling took matters into his own hands. In order to build this crescent-like jump bridge, the lava lake had to give up some more land. So the flame absorbing disk was used, one was not enough, Luo Ling used the spare crystal stored in Tarazin earlier to make two more sides, not the flame flow device, directly from the lava lake to absorb fire element energy crystals, heat energy solidification crystals.

Fire elemental energy is a relatively core and essence substance, and the heat energy is relatively much worse, but now in order to be able to quickly cool out of the rock formation, the next level of refinement is also acceptable. In this way, under the work of three or three flame absorbing disks, a pier-like terrain gradually condensed on the shore of the lava lake. Of course, the process of condensation became slower as the depth of the lava lake ahead intensified, but in general, the progress was relatively smooth.

With the determination of the route, and the rapid completion of the most basic part, the servants mainly of the fire dwarves went down to the shore of the lava lake to start a series of expansion work, in addition, the drilling team can also come down, Luo Ling dug a section of the tunnel above the dome, enough to put down the drilling machine, and the follow-up work is naturally completed by the machine.

6,000 people, 7 days of consumption, this is a lot of money, Luo Ling did not order to reduce the quota, but ordered to expand on the spot, the burning army is not gone and never look back, it is likely that it will go out from here in the future, and establish a bridgehead, which should be regarded as a train transfer station, there is nothing bad.

The Rock Crystal Civilization has made the Burning Army an absolute rock gnawing clan, and this gnawing work is much faster than the modern mechanized operation of the earth, as long as there is magic energy, large chunks of rock can be cut down and then transformed and used. With the construction in full swing, the originally narrow passage soon became a rectangular hall, and the space is still expanding with an area of nearly 10,000 square meters per day.

Most of the quarried rocks were made into various profiles, which were used in the erection of guide rails and other aspects of construction, and by the fourth day, a 30,000-square-meter planting area had been formed, and a greenhouse-style enclosed area was established, using starlight crystals and spirit gathering arrays to grow mushrooms that were almost ripe in a day.

At this time, Luo Ling and a few small leaders had already crossed the lava lake and were further exploring the road ahead.

Interestingly, the lava lake is a few kilometers away, is a huge glacier dome, giving people the feeling that they have just come out of Sang, and they have come to the cold storage here The temperature here is lower than minus 60 degrees, frozen like steel, and this glacier dome is very vast and huge, it can be said that it is the largest dome that Luo Ling has seen since entering the dark and dark area. Gregory told Luo Ling that according to his perception, he had to drill a hole from here and continue to the lower level in order to enter the main path, and if he went straight, the passage at the end of the glacial dome was upward.

However, this is not the point, the point is that under this glacial dome, there is another lava layer, that is, if you don't get it right, this is a vent of lava heat, and the result will be that the stability of the glacial dome will be affected, and there will be unpredictable consequences.
