The nine protective towers of the ancient city were opened, and a huge protective shield immediately appeared around it, allowing the entire ancient city to be protected inside.

The thunder protection platforms at the four corners of the ancient city were also under the control of the small balls, and they were all opened. Each Thunder Protection Tower emitted a powerful electric current, which could be seen by the people around it, and the dark blue electricity of the world was connected together, forming a wall of thunder and lightning on the four walls of the ancient city.

This thunder shield is like a thunder coat for the ancient city, and anything that touches it will inevitably be electrocuted.

The officers and soldiers who were originally guarding the walls of the ancient city were very scared in their hearts when they saw those demon spiders surging like a tide.

Now that they saw that the ancient city had such a powerful offensive and defensive facility, these officers and men were all excited. They surrounded Li Weiguo, raised their weapons high, and were ready to fight to protect the ancient city and protect the supreme leader.

Li Weiguo was very satisfied with the performance of these people, and if the fight had not started, and these people lost their combat effectiveness because of fear, it would be bad.

The torrent formed by the demon spider, suppressed by the fire of the defense equipment, rushed directly to the ancient city. These alien creatures were not afraid of danger, and jumped towards the city of the ancient city, and the bouncing power of these demon spiders was amazing, and they were more than ten meters high in one jump.

Li Weiguo even felt that if the walls of the ancient city were higher, these spiders would be able to jump up. While observing the movements of the demon spider, he beckoned the officers and soldiers around him, and immediately fired freely at the demon spider that rushed over.

The officers and soldiers guarding the city wall, all of whom were mecha divisions, immediately burst out with strong combat effectiveness after overcoming their fear of demon spiders.

Those jumping demon spiders were shot down from the sky by the officers and soldiers on the city wall. More demonic spiders rushed up and crashed directly into the lightning grid, turning into a charred corpse.

But these demon spiders, as if they don't know what fear is, even if the demon spiders in front are scorched by the power grid, the demon lord who rushes up behind will still rush forward without hesitation.

As more and more demon spiders slammed into the thunder grid, they soon used their corpses to pile up a path to death on the walls of the ancient city.

Li Weiguo has always paid attention to the situation in this position, and saw that the enemy had paved the road. He took the Iron Shield Giant Armor Brigade of the Ministry of Guards, and rushed out directly, and the torrent of steel was like the autumn wind sweeping away the leaves, directly knocking out all the demon spiders on the road.

Just a few back and forth, with the cover of the city's defensive weapons, all the demon spiders that rushed up were cleared.

When he returned to the ancient city with the Iron Shield Giant Armor Brigade, he was already exhausted and out of breath. He rushed to the front, and as the spearhead of the charging team, he consumed a lot of vitality.

The situation of the Iron Shield Brigade is not much better, and each giant armor has some damage on its body. The saliva and blood of the demon spider are very corrosive, and if you touch it slightly, it is a big hole.

The attack of the alien army was far from stopping, and after the demon spiders were repulsed, several giant demon unicorn fairies came out of the demon spider group.

This giant demon unicorn is bigger than the size of the iron shield giant armor, and it is more than ten meters tall, which is basically the same as the city wall of the ancient city.

These demonic unicorns have a huge horn on their heads, their skin exudes a metallic luster, and their size is so large that the earth trembles as they move.

The second brigade of the guard department, under the leadership of a captain, rushed directly towards these demon unicorn immortals.

The strength of this captain is not bad, he has the strength of the Yuan Infant level, and he can use special abilities. As he charged, he used his combat skills to release golden light, enveloping the entire brigade of iron shield giant armor inside.

Li Weiguo looked at the changes on the data board, and after the golden light blessed iron shield giant armor, the defense ability was increased several times. His eyes couldn't help but light up, and he felt that this was a talent that he had to cultivate in the future.

This person's name is Fan Jingang, a graduate of the Liangguang Military Mecha Division Academy, who has three years of experience in border combat, and has also stayed in the guard department for more than ten years.

It was also when Li Weiguo checked these data, Fan Jingang had already rushed to the side of the Devil Unicorn Fairy with the iron shield giant armor of the second brigade.

They immediately launched a large-scale concentrated fire attack on the devil unicorn, but it was a pity that the laser cannonball hit the body of the poisonous demon unicorn, and there was no way to cause any damage.

On the contrary, it was the demon unicorn immortal, stomping his foot violently, creating a wave of qi, and directly flew out all the iron shield giant armor of the second brigade first.

It is also thanks to the ability of the Iron Shield Giant Armor to fly, and after it was turned on in time, it was finally not too damaged.

The Demon Unicorn Immortal did not stop there, but raised the sharp horns on his head high and began to gather a large amount of thunder and lightning power.

Li Weiguo stood on the wall of the ancient city, looking at the energy on the sharp horns of those demon unicorn immortals in the distance, and he also had a huge sense of threat.

He hurriedly beckoned Xiao Qiuqiu and used the laser cannon of the ancient city to attack these unicorns. The idea is very simple, that is, to interrupt the accumulation of these demonic unicorns and not give these enemies a chance to attack.

The six laser cannons in the ancient city immediately turned their muzzles and bombarded these demon unicorns. The power of the laser cannon is very powerful, and the cannonballs of the giant cannon hit the body of the demon unicorn fairy, making big holes.

It's a pity that these demon unicorn immortals have extremely tenacious vitality, even if their bodies are punched out of a hole, the power of thunder and lightning on the unicorn has not dissipated, but instead fired a thunder beam in advance towards the ancient city.

The lightning and lightning struck the protective shield of the ancient city at the speed of light, and several large holes were hit in an instant, and then hit the second protective shield of the ancient city, and several holes were instantly punched, and finally these lightning beams hit the wall of the ancient city, making several gaps, before slowly dissipating.

The demon spider that had retreated before rushed up again, and the target was the few gaps that the demon unicorn had made just now.

Behind the demon spider group, a large number of demon scorpions came out, the tail of this kind of thing, which can spray a large amount of venom, and the damage of venom is very high.

Several of the ancient city's defensive cannons were shot by the venom of these demonic scorpions, and they immediately turned into a pile of scrap metal.

When Li Weiguo saw the enemy's army, he once again rushed to his side, and he could only mobilize the reserved reserve pair to the city wall to defend.

The number of enemies is too much, and there are big problems in the defense of the ancient city. In several places, there were already demon spiders, under the cover of demonic scorpions, rushing to the interior of the ancient city.

Li Weiguo saw that the situation was a little bad, and was about to personally lead people to rush up to plug these gaps. However, before he could leave, he saw Yuan Quan and Wu Mei, two people, with members of the Dragon Sword, killing them from a distance.

Their strength is very strong, and there are quite a few people who came over this time, and there must be thousands of people according to rough statistics. Everyone has the strength of Jin Dan and above, and all of them are third-class mecha masters.
