Liu Yu cleaned up his mood, ran forward again, and after dozens of breaths, stopped suddenly. There were two red dots lit up in front of him, and it was a pair of red pupils. Liu Yu squinted and looked closely, and in the passage in front of him stood a "armored soldier" wearing a heavy armor with an iron helmet on his head, a spear in his hand, and red eyes.

The red-eyed armor soldier rushed towards Liu Yu, the iron spear in his hand swept forward, Liu Yu drove the dantian spiritual power, poured into the flashing red sword with all his strength, and slashed forward with the red sword.

With a "bump", the two fought hard, Liu Yu was shocked and flew back five or six steps before he stabilized his body, while the red-eyed armor soldier did not move at all, and he was unforgiving, stabbing at Liu Yu with a spear.

Liu Yu endured the numb hands and the discomfort of churning blood and qi, and retreated sharply, dodging the direct stab of the spear. Suddenly, Liu Yu fell into a passive situation, the red-eyed armor soldiers chased after him, attacking frequently, Liu Yu could only dodge left and right, or retreat, without the power to fight back.

A few rounds later, Liu Yu dodged a horizontal slash from the spear, and the spear smashed on the stone wall, smashing half of the wall, which was extremely powerful.

After several rounds of fighting, Liu Yu roughly felt what the red-eyed armor soldier was, it should be a kind of machine person, according to the power and speed of the red-eyed armor soldier's attack, Liu Yu speculated that the red-eyed armor soldier had the strength equivalent to the ninth layer of qi training.

The red-eyed armor soldiers are tireless, the power and speed of the attack are above Liu Yu, the scene is quite dangerous, Liu Yu's quick dodge has consumed a lot of spiritual power in the dantian, and the physical strength is also a little unbearable.

There is no way, if you continue like this, you will soon be defeated, Liu Yuyi gritted his teeth and drove his spiritual power to display the "Xuanxue Escape". Liu Yu's blood all over his body began to flow extremely fast, and his face was congested, which was extremely terrifying. With the burning of essence blood, Liu Yu's body technique is getting faster and faster, and the red-eyed armor soldier can no longer keep up with Liu Yu's speed.

The red light of the flashing red sword, as Liu Yu's speed became faster and faster, turned into afterimages in the dim secret passage, which was dazzling. The red-eyed armor soldier had already been hit by Liu Yu several times, and the flashing red sword left several scars on the red-eyed armor soldier's body. But the red-eyed armor soldiers were still alive and well, and they were not affected in the slightest.

The machine man is made of cold iron, has no body, and is characterized by high defense, resistance to fighting, and a tireless fighting machine.

The Flashing Red Sword is of high quality and extremely sharp, and it can break through the outer armor of the red-eyed armor, but Liu Yu's cultivation is not enough, and the spiritual attack power is not enough, so it cannot cause a fatal attack on the red-eyed armor. It can't be like the deep forest rock tiger, which consumes the red-eyed armor soldiers, and narrowly enters a stalemate for a while.

Liu Yu was very anxious in his heart, because he had not fully mastered the "Xuanxue Escape", and the essence blood was consumed too quickly when casting the spell, and it did not last long. If this time is missed, Liu Yu can only wait for defeat.

"Is it a secret technique that consumes essence blood and improves the body? Interesting!" In the void above the illusion, a middle-aged Taoist asked himself softly.

The middle-aged Taoist's name is Sikong Ming, a cultivator in the late stage of foundation building, and a deacon of the Phantom Martial Hall of the Yellow Holy Sect. Originally, I just wanted to see if Mu Tianming had grown, but I didn't expect to find an interesting little guy.

Liu Yu stabilized his mind and tried to recall what he had learned in the Chuyuan Palace. Organ man, a branch of organ art, uses various spiritual materials to refine the birth drive, driven by the spiritual power of spirit stones, and is widely used in all aspects of battle, production, and life in the cultivation realm.

The red-eyed armor soldier is one of them, wearing heavy armor and tireless fighting machine that knows no pain.

Liu Yu remembered the explanation given by the lecturer of the Yuan Hall at the beginning of that year to the combat organ people, and the refining of the combat organ people should consider several important aspects, including flexibility, power, and spiritual intelligence.

First of all, to refine a combat man, we must take into account the problem of the flexibility of the man, if the refining manifold is not flexible and very bulky, then no matter how powerful it is, it is just a living handle.

Combat mechanics often use metal spiritual materials with amazing defensive power to refine their body drives, so that they can fight for a long time and efficiently. It's just that the hardness of the metal spirit material is high, and it is not flexible enough, and the refining mechanism is too slow to move, which is a headache.

In order to overcome this problem, refiners often use spirit mud to refine the joints of the trap and improve the flexibility of the trap.

After the spirit mud is fired, it can still maintain good ductility, which greatly enhances the flexibility of the mechanism. The limbs, body, and head of the combat machine are still made of hard metal spiritual materials, so that the people who refine the battle pass are both flexible and resistant to beating.

The red-eyed armor soldier was dressed in armor all over his body, with a heavy helmet on his head, and he was tight, revealing only his eyes, and his eyes did not know what to use with hedrons, and they were glowing red. The movements are sensitive, and the combat power is extremely strong, so when you want to refine it, you should use spiritual mud.

Liu Yu doesn't think much about it, a dead horse is a live horse doctor. When the red-eyed armor soldier stabbed a shot, Liu Yu used his quick body to stagger his body, and stabbed at the joints of the red-eyed armor soldier's forearm, revealing a trace of gap, and the flashing red sword pierced through it very easily, obviously Liu Yu guessed right.

Sikong Ming in the void nodded, secretly saying that this kid still has a trace of understanding, and he has grasped the key in a short period of time.

Liu Yu clenched the flashing red sword and cut it sideways left and right, cutting off the forearm of the red-eyed armor soldier. The red-eyed armor soldier lost an arm, but he didn't know the pain, so he grabbed the spear with one hand and swept towards Liu Yu. Liu Yu knew the weakness of the red-eyed armor soldier, so he seized the time, flashed the red sword in his hand and shot frequently, and quickly cut off the limbs of the red-eyed armor soldier, making the red-eyed armor soldier unable to move.

The red-eyed armor soldier lost his limbs, lying on the ground and uneasy, shaking constantly, wanting to stand up and continue to fight, this is the terrible thing about the machine man, the spiritual power is continuous, and the battle is not stopped.

Liu Yu leaned against the stone wall on the side, panting heavily. The "Xuanxue Escape" has stopped running, but the battle has consumed Liu Yusancheng's essence and blood, and his vitality has been greatly damaged. Liu Yu took out a blood pill and took it, took a deep breath, and Liu Yu walked towards the red-eyed armor soldier who was lying on the ground.

Liu Yu held the flashing red sword high with both hands, pointed it at the neck of the red-eyed armor soldier, and slammed it down, but he was embarrassed to find that the flashing red sword was stuck, and the red-eyed armor soldier's neck competition did not use spirit mud.

After thinking about it, Liu Yu understood that for the organ, the head does not need to be very flexible, just a simple shake from side to side, and the neck of the organiser is connected to the head, which is extremely important, and it is also made of refined iron.

Liu Yu used ten percent of his spiritual power, clenched the flashing red sword with both hands, and pressed it downward, and the sword body pierced into the neck of the red-eyed armor soldier little by little.

After a few breaths, he finally pierced the entire neck, and the red-eyed armor soldier gradually lost his movement, and the red light of his eyes went out. The neck contains the important spiritual veins of the machine man, and after the line used to transmit spiritual power was destroyed, the red-eyed armor soldier lost power and died completely.

As soon as Liu Yu wanted to pull out the sword body, the red-eyed armor soldier's body dissipated into the air like smoke, after all, it was just an illusion that transformed into an object, and it disappeared automatically after being defeated. Liu Yu did not delay either, and continued to move forward along the passage.
