World of the Ring, Middle-earth, Mordor, Black Gate.

Aragorn looked speechlessly at the magma lake in front of him, this magma lake covered the entire passage, although it made it impossible for the enemy to counterattack, and at the same time blocked the way of his troops, and at the same time made the temperature of the camp much higher, especially in this hot summer, now the temperature in the base has exceeded forty degrees, and the soldiers have to consume a lot of water every day to keep their bodies hydrated.

At the same time, the water sources here in Mordor have all been polluted, and they can't use it at all, so they can only rely on the fresh water reserves they brought when they went out, but this situation is completely unexpected, in the short five days they stayed here, they have already consumed the amount of clean water for the original month, and in a few days they can only retreat due to the lack of fresh water reserves. This reason for retreat is probably the most ridiculous reason in the history of Middle-earth, and they will also be recorded in history and ridiculed by future generations. Because the magma lake that caused this reason was made by their magic.

And if he retreats, Aragon is also very unwilling, because at this time, the Black Gate that was finally captured, if he retreats, it will be equivalent to returning this strategic place to Sauron, and next time, who knows how much it will cost to be able to recapture this position.

And this magma lake is the result of the explosion of the forbidden spell, it has been filled with a large number of fire elements, even if you use water or ice magic, there is no way to get rid of it, and this place is originally a place where the fire element is strong and the water element is lacking, this explosion makes the fire element here more active, and even some meaningless fire element creatures have begun to be produced in the magma lake.

And it is precisely because of these unconscious fire elemental creatures that it is impossible to move forward even if they build bridges, because these fire elemental creatures will attack everyone who enters the range of the magma lake. And as time passed, the number of these fire elemental beings increased.

Of course, in fact, their troops can use the refractory prism of the spear of Arden to jump their troops to the area behind the magma lake, but the main problem of the combined forces of humans and elves now is the lack of water reserves, even if they jump in front of Balado, with their current water reserves, they will not be able to last many days, because next to Balado is the Doomsday Volcano, where the temperature is higher than here due to the influence of the volcano, and their current water will not last long.

So now we can only wait for the supply of fresh water before we can move on. And Mordor's water sources have been polluted, so only by returning to Gangze's territory can you find a clean water source.

Of course, this mission will take a long time for the soldiers to return to Gangze's territory, so the Middle-earth team took over the task, leaving the Arden Spear with a reverending prism here, while the others left the base car to return the same way.

With the flight speed of the base car exceeding Mach 4, the original journey of more than a month was only a few hours. After the base car landed, a large number of robots came to the river with wooden barrels, and then started the pumping pump, which kept pumping the river water into the bucket. These buckets have been transformed, although the storage equipment in this world is still relatively scarce, but for these storage vessels that are only a single reserve of water, especially the wooden barrels for military water storage, after a large number of mages have been able to transform ordinary barrels, and then expand the internal space, this technology has been very mature, of course, only for ordinary water.

When he came out, Aragorn gave Li Nan a million wooden barrels, and Li Nan didn't know how much water could be filled in the internal space of these barrels, but Aragorn said that as long as they were full, it should be enough for them to use. However, at this time, it seems that the internal space of these barrels is quite large, because the pumps have been running for almost an hour, but the barrels still show no signs of being filled. But at the same time, the water in this big river is quite sufficient, and the water level in the big river has not dropped after pumping water for so long.

After two hours, the barrels were finally filled with cool river water, and then Li Nan had the robot set them up, and then used the Arden Spear to turn the barrels and base carts back into the camp at the Black Gate. Because Li Nan and they set off at ten o'clock this morning, when they arrived at Dahe, it was already more than four o'clock in the afternoon, after a few hours of loading water, now it is completely dark, if you have to fly back for a few hours, then it will be almost tomorrow morning when you return to the camp, so do you still want to sleep, so this is also the reason why Li Nan left a prism in the camp when he set off. Of course, in order to avoid the lack of water or other resources in the future, Li Nan asked the Spear of Arden to a hidden place near here, leaving a camp of star spirits, and the next time he needed water or other resources, he could just jump back here, and the distance from Minas Tirith was only about half an hour, of course, it was the flight time of Li Nan's base car.

When Arden's spear jumped, the next moment everyone was in the camp, along with the million buckets. Aragonese soon received a report of their appearance, and a large number of soldiers were sent to carry all the buckets into several warehouses in the camp.

And the problem of water has been solved, and Aragorn is also relieved, according to him, this clear water, even at the current rate of consumption, is enough for this 1.5 million coalition army to consume half a year, this time should be enough to defeat Sauron, or they will return from defeat.

And after the water is replenished, you can carry out the follow-up things, in the face of this huge magma lake, even Gandalf can't do anything about it, because the forbidden spell of Doomsday Gandalf is also used for the first time, and he has no idea that it will cause such follow-up damage. Now in that magma lake, more than 20,000 elemental creatures have been generated. And these elemental creatures are mainly second-order ordinary fire elements, as well as thousands of third-order elite-level giant fire elements, and there are also about a hundred fourth-order magma giants.

These elemental creatures usually hide under the lava lake, but when someone attacks the lava lake or wants to cross the lava lake, these elemental creatures will feel that their territory has been violated and will fight back collectively. Moreover, there are a large number of active fire elemental particles here, so basically every few minutes an ordinary fire elemental is generated, so even if the human army has launched many attacks against them, the number of these elemental creatures has not decreased at all.

Just yesterday afternoon, the captain of the Northern Ice Team, Gunniel, once consumed ten water energy stones at one time, and then activated his own skills, but failed to lower the temperature of this magma lake, but the frost provoked the riot of the elemental creatures in the lake, and then launched an attack on the human camp. In the last battle, one-third of the human camp was burned, but fortunately, these elemental creatures were produced because of the overactivity of elemental particles, and they did not have souls, so they did not have the blessing of legion energy, so this time the human troops were beaten quite badly, but there were not many casualties, which was a blessing in misfortune.

In this battle, the number of fire elements was greatly reduced, but what everyone didn't expect was that the next day, the magma lake was once again crowded with all kinds of fire element creatures. So Aragorn, they have given up on forcing their way through this lava lake.

And in the past few days, they have basically explored the division of the fire element creatures into their territory, as long as they pass through the sky at a height of more than ten thousand meters, these fire element creatures will not attack you, this is the only channel that can be detected so far. For the others, even if the magma lake is still hundreds of meters away from the cliffs on both sides, even if you walk against the cliff wall, you will still be attacked by the fire elemental, so there is no way to pass on the ground.

So the plan now is for the leaping prism of the Arden's spear to fly over a height of more than ten thousand meters, and then jump the entire camp over the plain beyond the valley.

However, this is not an easy task, these refractive prisms are only about fifty meters long, and the maximum range they can retort is the range of ten kilometers in diameter centered on them. And now there are only ten refractive prisms that can be mobilized, and there are five on each side, so the range that can be reincaped is only five circles with a diameter of ten kilometers. The entire camp adds up, but it takes dozens of jumps to fully teleport over.

Not only does it take a lot of time and energy to do so, but who knows if those energy fluctuations will stimulate the elemental creatures in the magma lake during the twist and turn, causing them to riot again. However, they didn't have a better way, so they had to do it head-on.

Early the next morning, in the fortifications not far from the magma lake, the original earth wall was easily broken through by the fire elementals, so this time a layer of hard ice was added to the outside of the earth wall. At this time, a large number of soldiers are stationed here, and they have all activated the legion's energy, and they are on guard against the magma lake.

And because this distance is beyond the territory of the elemental creatures, the magma lake is still calm, and the elemental creatures inside do not react at all. Five of the ten refrillators in the base began to slowly rise into the air until they reached an altitude of fifteen thousand meters. It was necessary to detect that the airspace of the elemental creatures was at an altitude of 10 meters, but for the sake of safety, the refractory prism was allowed to fly through the air at an altitude of 15 meters.

And when the refractory prism slowly flew safely over the magma lake, the elemental creatures on the magma lake were still not alarmed, and everyone couldn't help but breathe a sigh of relief. The number of those elemental creatures is not particularly large, the strength is not particularly powerful, and there is no legion energy blessing. But their attacks were all flame attacks, and after being killed, there was a violent explosion, and the previous earth wall was blown up by the explosion generated by the death of two ordinary fire elementals, and then those fire elements rushed into the camp, and they couldn't even stop it. Most of the tents in the camp were just ordinary tents, so they were quickly burned by the fire elementals, and they almost burned into the warehouses where the grain was stored. Fortunately, Gunnir built a huge ice wall to separate the flames from the storehouse, so that the grain could be preserved.

So having seen the horror of these elemental creatures, everyone doesn't want to fight them again, this kind of creature that explodes itself without saying a word is too terrifying.

Thirty minutes later, the five refractory prisms had reached their designated positions, and at the same time, the stage prisms in the camp also began to operate, starting from the camp outside the black gate. In order to avoid excessive energy fluctuations during the reflex and affect elemental creatures, only one refractory prism is activated at a time, and the second one starts to operate when the first recharge is completed. Although this is a bit of a waste of time as the first crept prism is recharged when the fourth one starts running, it is safe.

......

It's been two hours since I started to jump, and I'm still safe for the time being. In order to avoid being hit by the elemental creatures again, the camp had previously transferred everything to the camp outside the Black Gate, and now there are only 100,000 soldiers behind the ice wall left behind the Black Gate, and they will return to the outside of the Black Gate after everything in the camp has jumped, so that even if those elemental creatures make a move, they will have enough time to jump away.

However, the camp was only halfway through the jump, and it was still early for them to leave. However, Sauron has also been observing the situation here for the past few days, so he is also very aware of the magma lake that Gandalf has made, and he is still snickering on the side. So at this time, he would not have watched the coalition forces leap over like this.

On the coalition side, for the safety of the new camp, if Sauron raids this side, they must also have enough manpower to defend, so they are the first to jump elite troops and a large number of strong men, and they can only defend the camp here. So now in the camp at the Black Gate, most of the remaining soldiers are soldiers in charge of logistics and various supplies. The soldiers behind the ice wall who can really fight here are in the weakest state of defense.

And it was this time that Sauron had been waiting for. Nine Ringlings swooped down from the clouds at this time, and four of them, holding a stack of magic scrolls in their hands, threw them towards the magma lake, of course, these scrolls were activated in mid-air, turning into huge ice bombs and smashing into the magma lake.

The other five ringlings condensed a black energy spear in their hands, and then threw it at the five refractory prisms that were in operation.
