El Niño Line.

Since the demon blocked the passage and the demon suspended its attack for most of the day, giving Evra's people a little time to repair and build fortifications, the demon's attack on the human race has not stopped. They drive a flaming evil (Dota 1 Shadow Fiend) to take the lead, and the only way this evil creature can attack after charging into the human position is to blow itself up. One by one, the mobile bombs exploded in a large number of high-temperature flames and debris, which shattered Evra's fighters. It wasn't until Evra organized the death squad to drag them down, let the mages set up a series of frost circles at the predetermined location, and then pull the battlefield back to the vicinity of these circles, and use the freeze and frost magic inspired by the circles to freeze or frost these evil creatures when they charge - no matter how bad it is, it can also extinguish most of the high-temperature flames and some high-temperature fragments of frost and frost when they explode, and the human warriors' defense against demons is stabilized. The Gates of Hell collapsed after a few days of humanity fending off demonic frenzied attacks, without a constant supply of energy. In this way, Evra and the warriors came to the place where the gates of hell were opened after they had no constant backup after emptying the gates of hell. Due to the spatial shock caused by the collapse of the Hell Gate, the entire underground cave began to show signs of collapse, and after checking that the underground passage was blocked by the Drow mages, Evra's people withdrew from the underground passage. After that, the crater where the entire El Niño line was located gradually collapsed in a radius of nearly twenty miles from the cliff wall where the underground passage was located, and the entire landscape changed in an unknown way. If the underground races re-excavate the passage in the future, it will be their nightmare for these rocks that have not been tightly stabilized and collapsed. Since then, the entire underground passage has been buried deep under the rocks. The original El Niño line no longer exists.

Some people may wonder why the mages were not allowed to bury themselves in the circle like Drow mages and blow up the passage and block it. First of all, the underground passage occupied by humans is only the edge of the first cave space. It's not very far from the surface of the earth, and it's also the front line of the previous confrontation with the underground races. The enemy will not give you the opportunity to set up and activate the circle. Secondly, even if you blow up the first cave space, because of the existence of the second cave space, the enemy can dig diagonally upwards from the second cave, and with the stable rock structure of the second cave as a backing, those unstable blow-up first cave rocks will be easily dug up, which is equivalent to indirectly helping the underground race to shorten the opening of the exit to the surface. Only by blowing up both caves can they really block their exits. To be viewed from a cross-section, this is a space of two caves that resembles the location of two stepped steps.

Evra's people withdrew from the terrain change zone, looking down and sad as they looked at the smoke and dust that had dispersed from the sky. In the time spent resisting the onslaught of demons, more than half of the 6,000 elite warriors had lost. And that's still in a small passage. If the attack had been a little too late, if the demons had been allowed to protrude through the passage, or if the gates of hell had sustained energy, the losses would have been even greater. And it is also sad that General Guderian and Archmage Natasha did not see anyone dead or dead.

After the terrain changed and stabilized, Evra's people led the mage group to make a detailed reconnaissance of the collapsed area, and after getting the result that the underground passage was completely blocked, they sent the battle reports of the past few days to the Yanjing military headquarters and the Maginot defense line. Evra then led his troops to remain stationed nearby, awaiting the arrival of the military headquarters for final confirmation and transfer. It wasn't until more than a week later that Archmage Gandalf personally came to confirm that the passage had been blocked, and brought an order from the military headquarters that Evra lead the troops of the original defense line and Achilles, who temporarily led the new troops of the Dragons on behalf of Guderian, to rush to the Inca Empire to help. At the same time, the Maginot Line also drew part of its forces and asked General Augustus to lead it to join Evra and Achilles together.

At this time, the situation on the continent was deteriorating. The Inca Empire, supported by the continuous strength of the underground race, has been crumbling and is now gone...... It's not far away. The royalty and nobility of the Inca Empire fled to the Dayu border. Most of the underground passages in Dayu and Totai have the same situation as the El Niño Line - the underground races use the Hell Gate to release demons to drag the soldiers of the defense line, and at the same time, they also use the spatial shock generated when the Hell Gate collapses and collapses, and cooperate with the various magic circles planted by the Drow mage to blow up and block the underground passages, and the same is true for the passages in the United Kingdom. In this way, the troops drawn by the three kingdoms began to be abundant, and for a time all the three kingdoms sent more reinforcements to the walls of Asgar and the Inca Empire. The battle with the Sea Tribes on the eastern border of the United Kingdom is also still stalemate.

During this period, a large number of refugees from the Inca Empire poured into the United Kingdom and the Dayu Empire, and some ill-intentioned people also took advantage of the opportunity, which caused great headaches for the United Kingdom and the Dayu Empire.

This is what happened in the week or two after Guderian and Natasha went deep into the underworld.

——————————————————

I'm the dividing line

Guderian and Natasha never came out of the lich's tent. Eating and drinking food that the lich had stolen from Drow and kobolds - Fortan Ullith never imagined that he would one day become a thief. As for Ra and Sa, there was no choice but to solve it in the tent, and then it was secretly evaporated and burned by Natasha with magic - although the two who have become lovers have not yet had a further relationship, they are still a little twisted about these more private personal behaviors, and gradually get used to it.

The camp of the Minotaur and Drow has gathered six archmages and ten archwarriors since the lich arrived with Natasha and Guderian. According to the Lich, Drow is not much different from the great warriors of the Minotaur or other races, and the first-class masters of the human army, and they also have the same control of blood. It's just that there are differences in strength or agility because of the difference in size due to racial differences. As for the powerhouses that surpass the first-class, according to the Lich, they are all on the surface. The mage group on the abyss side, Guderian couldn't see what kind of species it was, only saw that it was a humanoid creature, and after asking the lich, he learned that it was a race called banshees - it is said that the spatial barrier between the abyss and the hell plane sometimes becomes weak because of its proximity to the center of the earth, and the descendants of the succubus born by the abyssal powerhouse forcibly broke the barrier and were born from the succubus of the hell plane for breeding purposes (see dota1 Queen of Pain), and all of them are females.

Since Guderian's arrival, there have been several battles, but there have been no larger wars. The Abyssal side, as Guderian had predicted, was only a tentative and expendive attack. As the defending side, the drow and minotaur can only pinch their noses to deal with the enemy's temptation and attrition, and there is no effective good way. It's just that in the next few attacks, the abyss side did not send out a lizard queue again-what Guderian saw that day, these lizard cavalry queues were about three thousand, and there were not many of them on the abyss side of this high-level army. Similarly, the Drow and Minotaurs did not deploy such high-ranking troops on the opposite side, and the kobold teams that had a queue and a commander and could cast nets did not participate in the battle. It's just that in Guderian's opinion, in addition to the lizard cavalry, the hole cards of the abyss are estimated to have some hidden troops. As for the Lich's summoning of the Sea of the Dead, the Abyss side also changed its tactics - summoning a lava monster (Dota1 Warlock's Stone Man) with the help of the lava lake under the abyss behind the plains. There is nothing the Lich can do about it.

Four days after Guderian and Natasha arrived on the surface of the Abyssal Front, the Lich brought news of the return of reinforcements from the surface to the underground.

"King Drow has sent 60,000 troops back to help, as well as ten archmages. It is now stationed at the other end of the passage. The head of the defensive line decided to launch a counteroffensive against the abyss in twenty hours. Fortan Ulis was in the tent facing Guderian and Natasha, who were sitting opposite each other eating. There was an hourglass on the table in addition to the food.

"Hmm. Won't the master come with us?" asked Guderian.

Fortan Ulis was silent for a long time, and there was a deep sadness in his eyes: "I...... Can I go back?"

"As long as the master is willing!, we will definitely explain it to the master. Natasha and Guderian looked at each other and said solemnly.

Fortan Julius was silent for a long time before he shook his head and said, "Forget it." I'm used to life in the underworld. And then there's a creature like me that has been transformed into a lich...... Continental ...... Even in the underworld, there will be no second person. I'm back to the surface...... Maybe it will hurt you. The underground world has accepted my existence, but the surface continent retains my past sins and mistakes, so let me live forever in this underground......"

Guderian and Natasha felt the vicissitudes and desolation in the depths of the lich's soul, and neither said anything more.

"I've been thinking about it for a long time, and there's no good way or excuse for you to leave openly. Only, after the Great War, you left with these two invisibility cloaks that I made improvise. As he spoke, he took out two black cloaks from his spatial waist and placed them on the table where Guderian and Natasha were eating, and continued: "These two cloaks will change with the environment and automatically blend into the surrounding environment. This is made from the skins of the underground demon lizards I collected from the drow mages. There are two energy circles embedded in it, which must be recharged every three hours, otherwise it will have no effect. ”

Guderian and Natasha curiously picked up their cloaks and flipped through them.

"Also, be careful, after wearing the cloak, the heartbeat and breathing cannot be hidden, and you must be careful to avoid those strong people or species with strong sensing ability. The map I have drawn for you will take a little time, the other roads are too dangerous and mostly blocked, and I have shown you the passage to the map that was given to you when I first rescued you. Fortan Ullis looked at the two men who were looking at the cloaks, his eyes full of kindness.

"Hmm. Thank you, Master. Natasha and Guderian stood up and bowed again to the lich.

"In the future, if I am assigned to fight on the surface, I will try to provide you with the information I can provide...... As for the fighting...... I don't know how to deal with it yet...... Perhaps, the best option would be to refuse a mission to the surface......" The lich turned, a little emotional.

Guderian and Natasha didn't know what to say. Fortan Ullis's current transformation, in his position, is extremely awkward for fighting humans.

"Okay, everything that needs to be said is said, before the big war starts, I will be on patrol around the area, you all be careful. Goodbye......" Fortan Julius turned to look at the two of them, and then left the tent without waiting for Guderian and Natasha to react.

Guderian and Natasha watched the lich leave, speechless, but both had deep helplessness in their eyes.
