The source of Osac Tower is no longer verified. But there is no doubt that it belongs to a powerful mage, or even a higher level. Whether it is from the shape, layout, or even internal collection, it can be seen that this is a powerful mage tower, and the mage tower must have a defense system.

Saruman had been staying in Osac Tower for quite some time. But he had never fully mastered the defense system of this mage tower. So he could only wait for it to be passively activated. However, despite this, the defensive ability displayed by this mage tower still made Lin Xuan look sideways.

In just a few breaths, Lin Xuan had tried various elemental attacks. He did not cause any damage to the protective shield. Lin Xuan couldn't help but become interested in it. Originally, he didn't have much idea about the magic of this world. But now it seems that there are still some advantages.

Alchemy runes lit up in the void. They flew straight to the body of Osactar and directly passed through the protective cover and penetrated into the interior of Osactar. The protection seemed to have some kind of judgment function. Once the attack range exceeded a certain limit, the defense magic array would be triggered. The alchemy runes had no attack power at all, so they were not blocked.

Of course, this defensive magic array may have had some loophole, after all, it has been too long. Otherwise, there should be a more complete mechanism. Alchemy runes should not penetrate so simply.

Alchemy runes penetrated into the tower body and quickly spread to every corner. These alchemy runes formed a huge formation and began to analyze all the material components of the tower in essence.

The entire tower was made up of super large giant stones. Although there was no trace at the interface, the clues could still be seen under deep analysis. It was difficult to be able to manipulate such a huge stone even with Lin Xuan's power.

The rock is an ordinary rock, but the entire boulder is filled with an inexplicable energy. It is somewhat similar to the divine power that Lin Xuan had come into contact with before. However, there is a certain difference in quality. This is a power of mixed mental power, magic power, and vitality. It has already had a prototype of fusion, but it is not mature enough.

The alchemy runes slowly transformed under Lin Xuan's whole process, and the entire analysis began to transform from the material level to the energy level. From Lin Xuan's magical perspective, countless lines were secretly distributed in every corner of the stone tower. But they all spread in the same direction.

Along these lines, a core finally appeared in Lin Xuan's perception. It was a burning sphere, which constantly extracted energy from all directions. At the same time, it was constantly returning them to various parts of the tower. The entire circuit was like the blood circulation system of the human body, huge and sophisticated.

"So that's it, the strange energy circuit forms an almost perpetual effect. However, the whole process is energy loss. The top array has a certain function of automatically absorbing the surrounding free magic. But it's still a little bit short of it. This magic array is only a little bit short of complete. But for some reason, the last error cannot be calculated well. Therefore, the entire array is actually in a weak state."

Saruman's counterattack brought Lin Xuan's consciousness back to the battlefield. At present, the soldiers of Gondor have completely suppressed Saruman's powerful orc. The war has entered a one-sided form. Saruman also felt something was wrong and wanted to escape. It's a pity that there was a Lin Xuan blocking in front of him.

"Witcher, I know what you want to do. I can't interfere with this, let me leave, and everything is over. I won't be in front of you again."

"There is nothing that cannot be traded. But your chips are not enough, so you have another chance to change the chips." A spear of lightning appeared in Lin Xuan's hand. The amazing aura made Saruman nervous. He felt that he could not take the move. The protection around him had already begun to weaken, and it was probably not enough time to last.

Saruman hesitated for a moment and made up some determination.

"I'll tell you a secret about Thorin."

Thorin still attaches great importance to his ally with Saruman. The Orcs have been bypassing Gondor and wanting to come to support Aisinger. The Orcs are not a particularly powerful race, but they have an extremely powerful advantage. The reproductive ability. The Orcs are almost the most reproductive life of almost all species. Their level of civilization is not high, but the Orcs are an omnivorous creature. During famine, these guys cannot starve to death even if they eat grass roots and tree bark. So this has led to an extremely large number of orcs.

Tens of thousands of orcs rushed towards Aisinger in a mess. Although there was no concealment, there were indeed not many forces in the entire Middle Land that dared to compete head-on. The orcs failed to obtain corresponding status because they had too many bad qualities and could not be unified. Unless they were iron-blooded means like Sauron, it would be impossible to gather them together.

At the foot of Masidras Peak, the Orcs were undergoing renovation. As long as you bypass the mountain, you would arrive at Aisinger. There was about a day left. But they didn't expect that Aisinger had already fallen and had not even been able to hold on for a day.

Some rocks on the hillside were pulled open, and some hill dwarves emerged from the hole. After quietly observing the foot of the mountain, they returned to the hole and moved out iron cylinders, filled with green liquid.

The orcs had a very sharp hearing. They noticed it when the orcs first started to act. Unfortunately, it was already a little late at that time.

Hundreds of iron barrels were pushed down from the hillsides in all directions. Many barrels were broken along the way, and green liquid spilled throughout the hillside. More barrels fell into the orc legion at the bottom of the valley. Many orcs were directly smashed into meat paste. But this was just the beginning of the disaster. With the fall of several rockets, purgatory came at this moment.

The rolling blue-green fire waves swept across the valley. With the violent explosion, they instantly spread thousands of meters. The miserable green flames had a strong magical color. Countless orcs wailed briefly in the flames and died. This tragic scene made the dwarves on the hillside stunned.

"Oh my God, we have opened the door to hell." said a dwarf in charge of archery.

“Will hell be like this?”

"Maybe."

The conversation was quickly interrupted by the tragic scene in the valley. Even as an opponent, the scene in front of him still made people feel uncomfortable. However, it was not the time to feel uncomfortable. Some surviving orcs began to try to climb up the hillside. Their number was too large. Even after the baptism of wildfires, nearly 10,000 people still survived. The surviving commander still had a glimmer of hope, because there were only a few hundred dwarves on the hillside. They still had an absolute advantage in numbers.
