In the main hall of the saint's ruins.

After the sixth wave of tests began, the surrounding walls turned into portals again, and in the green light curtain of the portal, this time it was the demons of the Burning Legion who walked out, first of all, a large number of demon guards, anyway, as the main force of the legion, they were responsible for opening the way everywhere.

Of course, now that the enemy has appeared, the Middle-earth team, as the defending side, will not let them assemble smoothly. At the moment when the enemy appeared, Li Nan immediately launched an attack on the enemy in the distance after receiving the order from the newly deployed robot legion.

After the previous test, Li Nan and Chu Xuan deployed the robot corps again, this time a total of one million robots were put in, 50,000 on each side of the alloy wall, and at the same time, 200,000 reserve personnel were ready to rotate below. And for the enemy 60 kilometers away, although the conventional weapons on the robot can't hit this range at all, in fact, the robot still has some backup weapons to choose from at this time, such as the beam rifle they are holding in their hands now, which can attack the enemy 100 kilometers away, but because the energy consumption is too high, it is not included in the list of conventional weapons.

Orange beams of light shot towards the demon guards who had just come out of the portal. One by one, the demon guards who had just walked out of the portal were headshot by the sudden beam, and then fell to the ground, trampled by the friendly troops who came out from behind. However, the attack of this beam rifle is unlikely to stop the assembly of these demon troops, because their rate of fire is too slow, the beam of one shot per second, and the barrel of the gun will overheat and need to cool after about a thousand rounds, and it is impossible to use it on a battlefield with a large number of enemies, and it is because of this that these beam rifles will be removed from the list of conventional weapons.

However, at the same time as these demon guards were attacked, the enemy also began to launch a counterattack, although these demon guards were in the physical system of short range, but their charge was accompanied by a large amount of hellfire falling from the sky. Tens of thousands of Hellfire rains were smashing into the camp of the Middle-earth team from the sky, and the bombardment of this amount of Hellfire was impossible to stop even if the defensive formation had recovered.

However, the defense of the air has not fallen, although Li Nan's capital ship Niang and some newly built powerful ship Niang are temporarily in a state of unusability, as for what they are doing? Now they are busy eating, because it costs 15 billion units of resources to carry out the fifth-order ship girl fusion, and just storing these resources is enough for them to be busy. At the same time, in order to ensure the smooth integration process, Li Nan still kept the selected shipwrewn in the best condition, and he couldn't fight anyway. However, the selected fusion objects are generally big sisters, so Li Nan still has a group of elementary school students who can fight. These elementary school students were used as escort ships for the fifth-order ship in the future, and all of them have been transformed into the form of space warships, so just now, Li Nan also deployed ten primary school students, Rafi, Walkland, Ziyingshi, Xili, Shiyu, Xuefeng, Shooting Fish, Iona, Kunming and the newly built Goddess of Dawn. A total of ten ships and eighty battlecruisers were added to the remaining battlecruisers, and at this time, the ninety battleships turned on their respective anti-aircraft guns and shot at the fireballs of hellfire that fell from the sky, and huge fireballs were exploded in the air one after another.

The current form of these elementary school students' space battleships is much smaller than the previous Enterprise's dozens of kilometers long hull, after all, they are only in the role of frigates. The length of the hull is five thousand meters, and the hull is cylindrical, okay Li Nan admitted that this is a copycat of the design of the Autumn Wind Pier, anyway, it is easy to use. Compared with the drawings that had been used before, the drawings of the Autumn Pillar were more suitable for Li Nan's style. Of course, as a frigate, the caliber of the main gun is not too big, because the enemy's main force has the big sisters to deal with, and the target of these elementary school students is the enemy's cannon fodder troops, so the main gun on the entire hull is only one hundred and twenty large-caliber solar ray guns, of course, the energy consumption of this 100-meter caliber main gun is also within an acceptable range, and at the same time, the power can also instantly break and even sink various small space warships. In addition to the main gun, it is a large number of laser cannon groups, which are used to deal with medium and long-range enemies, and a large number of launch ports are also arranged, and the enemy at close range is the response range of these various missiles, nuclear bombs and erosion warheads, of course, in order to deal with the battle in the atmosphere, a variety of small-caliber close defense guns are also installed a lot. In short, according to Li Nan's habits, all kinds of large and small turrets and launch ports are densely spread all over the entire surface armor of the ship, no matter which direction the enemy wants to break through, it is greeted by a full screen of beams, missiles, and shells. As a remnant of a multi-turret cult, looking at the dense black holes on the hull of the ship, Li Nan said that it was very comfortable to watch.

And following the first wave of hellfire, the second wave of hellfire rain attacks came again, and more than 100,000 meteorites with long green tails fell from the sky that could not be seen to the top again, and this time the hellfire attack range was no longer the camp range of the Middle-earth team, but the indiscriminate attack of the entire hall. However, this amount of Hellfire is nothing to the ship's girls, their laser cannon group is set up to deal with a large number of cannon fodder groups in a large area, in the five-thousand-meter-long hull, this kind of one square meter can be installed four twin laser cannon groups, and at least 100,000 groups are installed on the entire hull, this crazy design still takes into account the computing power of primary school students, otherwise a larger number of gun crews can be installed.

Faced with an enemy of this size, they are now only firing a tenth of their artillery crew. Combined with those AI-controlled battlecruisers, they easily exploded all the 100,000-scale hellfire rain in mid-air, including ten of them that were particularly large lord-level hellfires. Of course, for this kind of giant meteorites with a radius of more than one kilometer, ordinary laser artillery crews are powerless, but the 100-meter caliber solar ray gun, which is the main gun, can easily break these giant meteorites into pieces with just two activations, and then fire a few erosion warheads to annihilate all these fragments.

And after defeating two groups of enemies in the air firefight, the demon guards on the ground have also rushed forward for more than twenty kilometers. After all, there are too many of them, and they are still squeezing out of the portal, even if the robots on the alloy wall can kill tens of thousands of demons with each shot, but the portals behind can gush out hundreds of thousands of demons every second, in this case, the beam rifles of these robots alone cannot have the effect of clearing the field, and they can't even stop them from advancing. However, at this distance, these demons also entered the attack range of the treemen in the rear, of course, this is the last treeman entity to be released, and as for the treeman phantom formed by these vines, their attack range is thirty kilometers. And the main weapon of the robot, the attack range is related to the energy output, the attack range of the first level is ten kilometers, and then every time one level is raised, the attack range will increase by another ten kilometers, and in the face of these demons of the Burning Legion, after the data of the previous killing of the enemy, to deal with these demons need to use the energy of the three-level output, and the attack range is thirty kilometers. So until the enemy reaches this range, they continue to use the Beam Rifle to consume the number of enemies, albeit much less than the amount they pour out of the portal.

Of course, if the heavenly warships help, they will be able to destroy the enemy faster, but because the next enemy is likely to be these demons of the Burning Legion, so it is a rare opportunity, Li Nan and they now have to test the effectiveness of these latest robots in dealing with the demons of the Burning Legion, and at the same time, they also have to test the strength of this line of defense.

After the addition of the treemen, the attack strength on this side instantly increased by several levels, and the attacks of these treemen were still throwing stone projectiles, and each treeman could throw five stone projectiles with a diameter of about 100 meters at a time. These stone bullets thrown by the treemen with great force were able to smash dozens of demon guards to death the moment they landed, mainly because there were too many demon guards, and they were all densely packed together. At the same time, after landing, it will roll forward and rush for a certain distance, which can deal secondary damage to later demon guards, taking away the lives of dozens of demons again. In the end, these projectiles are all made of energy, so when they stop, they will detonate the energy in the projectiles, dealing a third damage to nearby demons. Generally speaking, each stone bullet can kill about eighty to one hundred demon guards, and the one thousand stone bullets thrown by two hundred tree people can kill tens of thousands or even more than 100,000 demons each time, smashing out pieces of open space in the dense demon ranks, but the demons that sprung up from behind can instantly fill these open spaces again. Overall, although the speed of clearing the demons is much faster, it still can't stop the speed of these demons.

Five minutes later, the demons had rushed thirty kilometers beyond the Rim Wall, and now both the robots' main weapons and the Treant Phantoms had already entered their attack range. However, in this process, the robot uses beam rifles and tree man's stone bullets to destroy millions of demons, but now the number of demons has not decreased, but the demons on the scene have become more densely crowded, and through statistics, the number of demon guards in this hall has exceeded 300 million.
