Little by little, they were going back to Fortaleza. Despite the fact that they managed to kill thousands of monsters in two hours, they didn't slow down the horde even a single bit. As if their hard work had been for naught.
"This is not working..." Leon clenched his teeth.
"Well... despite that, we killed a lot of monsters," Betty said.
"It can't be helped; your main strategy is to use the skeletons," Sasha added. "Let's not worry too much about this, and we still will see the railgun in action. So, all the hope is not gone."
Leon nodded; he had no doubts that such a weapon could kill a few T-Rexes in a single shot. The problem was, they don't have time to prepare such a shot. They could only shoot several times, hoping that it would kill dozen of monsters every time. Another problem with the railgun was the fact that even after receiving the necessary mana, it had to wait five seconds to be used. So, at best, the survivors would be able to shoot a single every ten seconds. Still, there was nothing more than Leon could do, so he kept killing the monsters as much as he could.
Eventually, they finally were back to Fortaleza, and Leon could see in the distance his skeletons and the barricades the population created. Much to his surprise, a blue beam of energy passed nearby them at a fearsome speed and hit the horde of monsters. The range of destruction left Leon speechless. With a single shot, the energy beam killed hundred of monsters, ten of them were T-Rexes.
"Jesus Christ... how did I survive that?" Leon frowned.
"I was wondering the same thing..." Betty also frowned.
Leon soon recovered his focus and started to kill the monsters while retreating. Fortunately, Pedro kept shooting every ten seconds; everyone was working hard, so things were looking good. When they were five hundred meters away from the first line of defense, Leon decided to retreat and join the others, but first, he made his skeleton wizards shot water balls as much as possible. The monsters were still out of their range, but that was fine, things would get interesting later.
After joining the others, only Pedro kept shooting using the railgun. Still, that wasn't enough to slow down the monsters. Two minutes later, the horde finally entered the skeletons range, and Leon gave the order to his skeleton archers shot Thunder Arrows. The horde of monsters was stepping on the mud that the skeleton wizards created by using water balls so many times, and the skeleton archers electrocuted them with ease. The mud amplified the power of the thunder arrows, and Leon managed to stop the first line of the horde successfully. It was finally time for the survivors of the city to do their job, so Leon used War Cry to help them a little.
"Attack!" Pedro shouted.
Leon wasn't aware of it, but Pedro bought hundreds of bows and gave them to even those who weren't used to the weapon. Despite that, thanks to Leon's combination of attacks, even those who weren't archers managed to hit the monsters. However, he didn't notice that, because he was too busy slaying monsters with his spears. Meanwhile, Betty, Sarah, and all the survivors who didn't have bows were waiting for their turn. The small monsters were dying like ants, but the big ones were resisting quite a bit. Unfortunately, it didn't take long before the bosses finally managed to free themselves from the Thunder Arrows. Pedro tried to stop them, and he succeeded, but his shots stopped hitting several hundred of enemies thanks to that.
"Keep hitting as many enemies as you can," Leon said. "I will deal with those that escape the Thunder Arrows."
"Got it." Pedro nodded.
That being said, even though Leon had the power to stop them, the horde of monsters was attacking too many places at the same time. Even with his speed, Leon wouldn't have time to finish them all. Still, there was nothing else that he could do.
Leon, Betty, and Sasha flew toward the horde to draw their attention. However, only a few monsters paid attention to them. Instead of trying to eat those three, the horde was more interested in eating those thousand of humans who were ahead of them. Leon felt thankful but also annoyed due to that, he slaughtered monsters at fearsome speed, but they didn't pay enough attention to him. They retreated a little, and Leon attacked the monsters who managed to escape the range of Thunder Arrows with his Steel Spears. Despite that, several monsters managed to reach the barricade, and they were ready to kill the survivors who were holding their weapons, but at the same time looking at the monsters like scared kids.
"… I don't think so!" Leon shouted.
Using gravity, Leon stopped several of those monsters who were about to invade the city, and that gave the survivors enough time to react, but at the same time, Leon spent half of his mana to stop those humongous creatures. Even so, he didn't manage to stop them completely.
The T-Rexes looked at Leon; they seemed very angry, and even from far away, they opened their mouths to eat him. At least, that was what Leon thought. They didn't open their mouths to eat him, but to attack. Those massive dinosaurs spat fire toward Leon, Betty, and Sasha almost became ashes because the range of their attacks was surprisingly long and because Leon got caught off-guard.
"Are you serious? They can use Fire Breath?"
Then Leon understood, as the earth dragons, the T-Rexes were considered dragons that couldn't fly. That was the only explanation… still, Leon had an idea. After drawing their attention and making them use the Fire Breath, Leon positioned himself in front of other monsters. Thanks to that, the T-Rexes damaged each other greatly. Still… it wasn't enough to stop them.
