The giant python that was flying towards the river suddenly paused in the air, and then, its huge body began to expand rapidly, just in an instant, its volume had increased several times, and the pressure from the inside made the giant python finally overwhelmed, and after a sound similar to the bursting of a balloon, the blood rain in the sky fell from the body of the giant python that had become countless fragments.

The terrible screams came out of the river with the fall of the blood rain, and the originally turbulent river surface was flooded with rolling waves at this time, several huge black shadows tossed and writhed between the waves, the deafening roar and the size of the giant python, and the terrifying momentum between the actions, all made the soldiers defending the city tremble.

"They can't hurt you," Rhaegar muttered, "you're safe now." The geist made a gesture quickly, and several red pillars of light fell from the sky and landed on those black shadows, and in an instant, the demonic beasts that were still struggling to the death were sucked away by the negative energy in the red light, and turned into corpses floating on the surface of the river.

Both the Corrosive Light and the Blood Rain Technique, which Rhaegar had previously used, which had an improved version of the Blood Sea Technique, were both derived from Carson's notes, the former having an attraction effect on all life energy, and the latter infecting other creatures with poison in the blood of slain creatures. Of all the ninth-order spells, they weren't the most powerful, but they required the least amount of magic and were incredibly lethal.

"Hold this place," Rhaegar said to the terrified soldiers, "they shouldn't be attacking from here again, but you still have to be careful, not always a mage will come to your rescue." His body soared into the sky and flew towards the other side of the castle.

Rhaegar had already been aware of the existence of these monsters long before the attacking monsters were discovered by the guards, but the geist was well aware that these monsters were obviously not the real main force. The monsters that hid behind and did not participate in the attack may be able to fool the soldiers, but they cannot hide the perception of Rhaeggar, in fact, except for a few exceptions, most of them are only pretending, and even a strong farmer would not have much fear of them if it were not for the darkness of the night to cover up the true colors of these domestic and wild animals that were temporarily captured and forcibly injected with the blood of the monsters, so that they temporarily possess some of the physical characteristics of the monsters.

The appearance of the aquatic monsters approaching from the river confirmed Rhaeggar's thoughts, and after leaving the western wall, he quickly inspected the other two walls near the river, until he was sure that there were no other monsters lurking, and then the geist turned around and flew towards the southern wall, which was in the midst of a fierce battle.

"Heavy Guards, all press ——!" Salun shouted hoarsely, "Spear ready, collective stab!" He could only stand on the support of others now, but he still insisted on staying at the head of the city, commanding his most elite squad, a team of all Kohler's battle-hardened guards, to launch a fierce counterattack against the two powerful demon apes who had just ascended to the top of the city.

Dressed in heavy armor and armed with spears up to three meters long, these elite warriors chosen by His Majesty the Emperor from the Imperial Guards to keep their most beloved brother safe, lined up in a neat and tight formation, passing through their companions who had retreated in panic due to the presence of the Great Demon Ape, and rushed towards the giant ape that was brandishing wooden clubs to attack the soldiers, and the spears in their hands were raised high at the same time, stabbing at each other from all angles.

In the face of a sharp attack composed of dozens of sharp spears, even the mighty demon ape did not dare to take it lightly. The two demon apes let out a low roar, and they danced their sticks the thickness of an adult's thighs quickly back to back, fending off their opponents' viper-like attacks while trying to buy time for their climbing companions. However, their flesh and blood were unable to withstand the charge of the powerful heavy infantry, and after several spears flew and two heavy guards were severely wounded, at least a dozen spears made of steel pierced their bodies almost simultaneously.

The roar of anger accompanied by the final blow of the two demon apes rushed towards the victorious heavy armored infantry, and the two soldiers who were closer flew into the sky with their own armor weighing dozens of kilograms under the angry swing of the strong demon ape, and then, with the retraction of the spears, the demon beasts that had exhausted all their life force planted the city with blood sprayed all over their bodies.

"Where's the mage?" Sarun's roar rang through the battlefield to the ears of the squire, who was panting to the top of the city, and before the knight's apprentice could speak, a voice rang out behind the knight.

"Keep your people in good balance. ”

Before Sarune could understand the meaning of Rhaegar's words, a strange sound was already sounding up and down the city walls, not very loud, to be exact, it was not even more sound than a bee flapping its wings, but it clearly reached the ears of every creature within a few tens of meters of the city walls.

Almost at the same moment, all the creatures who heard the sound, whether it was the soldiers standing on the city, the Hercules ape climbing the city walls, and the armored rhinoceros that served as pedals, in their perception, the whole world began to spin rapidly, which made them feel dizzy like never before, and they fell to the ground one after another— For those soldiers, it was just a fall, and for those demon apes who had jumped high or had already grabbed the edge of the city wall, what awaited them was to fall back to the ground from a height of more than ten meters.

A white light swept over the soldiers on the city as soon as the sound disappeared, dispelling their dizziness in an instant. But the attacking monsters were far from so lucky, those demon apes who were seriously injured lost their combat effectiveness forever, even those who were only slightly injured and those who stayed on the ground when the sound sounded and thus avoided falling were unable to stand and move because of strong vertigo, they became the target of the soldiers who had returned to normal, bows and arrows, hot oil, stones, logs, all kinds of means that could kill and injure the opponent poured on their heads in an instant, and within a few seconds, the losses of the demon apes exceeded the sum of the times since the beginning of the war.

Another terrible wolf howl came from the horde of monsters behind, and after the failure of the forward attack, the leader of the monsters hiding behind finally became angry, and it gave the order to the only intact flying thorn pig in the siege group to attack indiscriminately - even if it failed, it would teach those hateful humans a painful lesson.

Once again, however, its plan fell through. At the same time as its order was issued, countless fireballs rained down from the sky and landed among the flying thorn pigs, these monsters with thick skin and thick flesh, not afraid of swords, but only with an innate fear of flames, suddenly fell into hysterical panic, whether they were burned by the flames or not, they all screamed frantically, and ran in all directions, even if the wolf howl sounded again and again, it was useless.

"Well done," Sarune could finally breathe a sigh of relief, his unprecedented exhaustion making him unable to stand again, "I'll leave it to you." He said to Rhaegar and fell asleep on his feet.
