The potion that had just been injected allowed Gu Tie to fully recover, both physically and mentally. Now the stimulus of this crisis has made him completely burst out of this energy worth 150 star diamonds. He ran like a fly, and the propulsion of psionic energy made him as fast as a mad dog with its tail on fire. He rushed to the top of the staircase and jumped hard, his body rushing to the top of the stairway as if he was weightless. He turned in the air and kicked the top, rushing sideways into the second floor. The phone alarm is still vibrating violently, and the screen has turned orange, indicating that the second floor is also not safe. Gu Tie continued to rush up the stairs, jumped and kicked again, and rushed to the third floor like a fish.

An earth-shattering tremor came from downstairs, and the ground suddenly cracked like a crack in a farmland, and the ancient iron that had just landed was staggered and pounced. He didn't have time to get up, so he threw himself on his hands and feet to a corner away from the staircase, and curled up in a ball with his head in his hands. A devastating shockwave then erupted from the staircase, carrying a large amount of flames and debris.

After the explosion, Gu Tie raised his head dizzily, the air was filled with dust and smoke, and there was a huge hole in the ground in the center of the hall. He staggered to his feet, unplugged his headphones and scratched his ear holes, feeling the wet water. He looked at his finger and saw that it was not water, it was blood. The explosion was so violent that his ear hole was bleeding.

Gu Tie gritted his teeth and cursed, walked to the hole to look down at the situation, and directly saw the smashed hall on the first floor, the vending machine was no longer there, and there were some familiar iron sheets scattered on the ground. "Oh, poor Terra, she must be. Gu Tie muttered, and then felt the phone vibrate again, the screen was blue first, then turned green, and a rocket was coming.

Gu Tie looked at the cracks in the surrounding walls and columns, and knew that if this continued, the building would definitely collapse. It is absolutely not safe to hide in a building, and jumping outside the building exposes you to the view of the attacker. Gu Tie hesitated for a while, but still jumped over the big hole and ran to the window of the last time he jumped off the building to attack the Turen. He looked left and right, but saw no trail of the rocket, and finally breathed a sigh of relief. The rockets weren't coming this way, the attacker wasn't in this direction, and he wouldn't have seen him jump out of the window right away.

Gu Tie jumped out of the window and used his psionic energy to pull his body and fly as far as he could. Before he could hit the ground, the rocket hit the third floor where he had just been. The violent shock caused the building to shake, and the shockwave carrying the flames spread up to the fifth floor and down to the first floor, spewing out of every hole. The giant vines wrapped around the building were shaken loose and broken.

Gu Tie was already some distance away from the building at this time, but he was still swept away by the aftermath of the explosion, rolling out of the air for an unknown distance, and then fell heavily to the ground, spitting out a few mouthfuls of blood. The crisis of death stimulates the potential for survival, and he quickly gets up and runs. The phone's alarm stopped for a moment, but it didn't take long for it to vibrate again, first blue, then green.

Gu Tie glanced back and saw a black dot holding a white trail in the distance. Another rocket! He ran wildly with the greatest force, and with the help of psionic energy, he took more than ten meters with each step, and glided almost without his feet touching the ground. But he knew that he was a rocket that he couldn't run, so he racked his brain as he ran wildly and thought about how to avoid the rocket.

He passed by the mouth of a wellhead that was spewing hot gas, but then stepped back and looked down at the well. This is supposed to be a sewer well, connecting to the building. The explosion in the building created a tremendous air pressure that rushed through the sewers, forming the current gushing white gas. This means that the sewers are connected, not occluded.

Gu Tie immediately jumped into the sewer and unexpectedly landed on a pile of soft plants. He took out his flashlight and looked around, and found that there were many colorful and beautiful mushrooms growing in the sewers, and under the light of the flashlight, these mushrooms were still glowing, and they looked very beautiful. Gu Tie didn't have time to admire the mushrooms, so he ran desperately when he found a passage. Not long after, the well he had just come down from was hit, and a violent explosion caused a series of collapses in the sewers. The rumbling falling gravel seemed to be chasing the brains of the ancient iron.

Gu Tie knew that this was a moment of life and death, so he ran wildly, but as he ran, he suddenly saw a group of monsters covered in black and with pointed heads like mice. At first, these monsters opened their teeth and claws at the ancient iron, but when they saw the chain collapsing, they turned around and ran. So, Gu Tie ran wild together in a group of stinking monsters.

I don't know how far I ran, but the chain collapse finally stopped, and Gu Tie and the monsters stopped panting. Monsters, you look at me, I look at you, and then stare at Gu Tie together, obviously not bad intentions. Gu Tie was silent for a while, then suddenly opened his hand to the four monsters on the left, and grabbed them with psionic energy and smashed them into the five on the right - in the past few days, he often used psionic energy to grab himself and float around, and he had long been accustomed to using psionic energy to grasp heavy objects. I saw four monsters fly up together, knocking over the five on the right hard. Gu Tie then pulled out his pistol and shot at the rolling monsters one after another. The explosive bullet is incredibly powerful, and the monsters are blown to rotten flesh with three shots.

Gu Tie then took out his mobile phone and stared at the screen, waiting for a long time without waiting for a crisis warning. He finally breathed a sigh of relief and switched to the Terra map to search around, but didn't see the vending machine icon. This made Gu Tie very uneasy, it was really difficult to move an inch without weapons. He now only had a pistol left, and three of the twelve rounds had been fired, leaving only the last nine.

No matter how you look at it, nine bullets are definitely not enough, which makes Gu Tie dare not even move. In case you walk a few steps and run into a group of monsters, how can nine pistol bullets be enough. But Gu Tie didn't dare to stay here, the smell of blood from these monsters would quickly attract other monsters. For a while, Gu Tie didn't stay, staring around in fear and nervousness. The panic quickly spread, and he turned on the flashlight and turned it off again. Turn on the flashlight, he is afraid that the light will attract monsters. Turning off the flashlight, he couldn't see the monster again.

Gu Tie was troubled for a while, and suddenly remembered something, after getting the first drop of blood, the goddess gave him a special reward.

This reward seems to be called 'Gun and Bullet Creation', and judging by the name, it should be able to create bullets.

Gu Tie hurriedly took out the spiritual energy book, clicked on the 'Exercise Your Spiritual Energy', and saw silver stars all over the screen, two stars in it were golden, one was 'Battle Mapping-Gun Array', and the other didn't know what it was. Gu Tie tapped it, and was pleasantly surprised to find that the name of the spell was really 'Gun and Bullet Creation Technique', a spell on how to create bullets.

The 'Gun and Bullet Creation Technique' is not recorded by Ancient Iron, and is different from the spells created by Ancient Iron itself. The previous 'gun array' was created by Gu Tie, who recorded the spells in the Psionic Book, and when it was time to use them, the Psionic Book transmitted the content of the spell to the heart of the Ancient Iron, making the Ancient Iron more convenient to use. This 'spear and bullet creation technique' was given by the goddess to the ancient iron, and everything is recorded in the book. Ancient iron cannot be used directly, you must carefully read every step, understand every link, and learn this spell thoroughly. When the Ancient Iron Society is established, you can directly use the 'Gun Cartridge Creation Technique', which is used in the same way as the 'Gun Array'.

After Gu Tie finished reading the spell, he smiled bitterly and sighed. The spell was quite ruthless, and instead of copper, iron and gunpowder, the materials used to create the bullets were the corpses of the enemy. Using a series of complex psionic transformations, the enemy's flesh and vitality were refined into gunpowder, teeth into bullets, bones into bullet shells, and hair and bone marrow into primers, so that the materials for bullets were complete. Cruelty is indeed cruel, but this cruelty is very practical, copper and iron and gunpowder may not be found on the battlefield, but there is certainly no shortage of corpses. Gu Tie didn't know where to find copper, iron and gunpowder now, but there was a lot of blood next to the corpse.

"This is really the essence of fighting to nourish war. ”

Gu Tie shone a flashlight on the pile of tattered corpses, sighed and shook his head, and continued to study the creation of guns and bullets. Bullet Creation can create many types of bullets, from small-caliber rifle bullets to large-caliber shotguns, and even magazines, provided that Furutsu knows the bullets he wants to create. The most common bullet consists of four parts: primer, cartridge case, gunpowder and warhead, and Gu Tie must have a deep understanding of these structures of the bullet, just like knowing his own fingers. He does not need to know what material the warhead is, but he must know the shape, size and hardness of the warhead, and he does not need to know the composition of gunpowder, but he must know the power of gunpowder......

Gu Tie had never studied bullets, but fortunately there were nine bullets left in the pistol. So Gu Tie took out a pistol bullet from the pistol magazine, disassembled the bullet with a dagger, and began to study this explosive bullet. This starting point is slightly higher for ancient irons, as explosive bullets are more complex than normal bullets. The warhead of an ordinary bullet is solid, and the warhead of an explosive bullet can be equipped with a complex ** and a fuse.

However, Gu Tie had no choice but to challenge the subject of a high starting point.

............................................................................................................

In the dark sewers, the sound of pistol firing was non-stop, accompanied by the rumbling of explosions. Hordes of kobolds were blown to pieces, throwing their bodies on the ground and fleeing in a hurry. Gu Tie took the opportunity to change into a new magazine and pointed a gun at the fleeing kobold. He didn't shoot, but just used a flashlight assembled under the muzzle of the gun to shine on the fleeing kobold, and then shine a light on the kobold lying on the ground, making sure that the fleeing kobold did not stay, and that the kobold who pretended to be dead did not get up. - After being scanned by the 'Naturalist Encyclopedia', Gu Tie learned that these creatures were named 'Green Forest Caveman Kobolds', a cowardly but cunning and cruel indigenous people who inhabited caves and sewers. However, Gu Tie was not interested in knowing what kobolds were, only that they were all magazines.

After all the kobolds fled, Gu Tie cautiously approached the kobolds lying on his stomach, opened his left hand to them from afar, and tested each kobold with his spiritual energy. A corpse jumped up at the slightest touch, barking viciously, and the other two kobolds who pretended to be dead also flew at him. Gu Tie had been bitten by a kobold who pretended to be dead before, and now he was mentally prepared. He unleashed psionic energy to grab them, slammed them on the ground and fired another shot, and after the gunshots and explosions, one kobold was shattered to pieces, and the other two were blown to a bloody pulp, and the whole body was finally preserved.

The intact corpse is convenient for refining bullets, Gu Tie nodded with satisfaction, and continued to use spiritual energy to test the other corpses. It wasn't until he was sure that each corpse was a real corpse that Gu Tie walked up to them, pressed his left hand against the chest of a corpse, and began to activate the 'Gun Bullet Creation Technique'. In his mind, he kept thinking about the explosive bullet, the shape of the warhead, the weight of the cartridge case, the explosive force of the ammunition, and the function of the primer ....... Silver light emanated from his hand, turning into countless silver threads that seeped into the corpse. The corpse then began to wither, not only the flesh and skin were decreasing, but even the bones were melting. In less than half a minute, the corpse had turned into a mass of withered fur.

Gu Tie tore open the fur and took out a delicate white magazine from it, and although he had seen it many times, he was still amazed at its beauty. This magazine is a white bone material, with a smooth and delicate surface and angular edges, like a finely carved piece of jade. The magazine contained the same beautiful white bullets, and the warm yellow bullets were like peerless ivory antiques.

"Where is this murder weapon, it is simply a handicraft. ”

Gu Tie sighed secretly, put this magazine in the tactical vest, and continued to refine the other corpses. After refining more than a dozen intact corpses into more than a dozen magazines, Gu Tie continued to explore the sewers, but his steps were slightly heavy. His psionic ability is still very shallow, and this 'spear and bullet creation technique' is still a bit of a burden on him. If his spiritual energy was more sophisticated, then one corpse could refine some more bullets, and it would not have to be so laborious, refining more than ten corpses would be dizzy and panting.

As he walked, he looked at the map of Terra, trying to spot the vending machine's icon, but he didn't see anything, and his heart became more and more uneasy. He had been walking in the sewers for most of the night, probably more than ten kilometers, thirsty and tired, and he was already very tired. Although the 'Naturalist Encyclopedia' shows that kobolds can also eat it, for humanoids, Gu Tie still has psychological barriers.

I don't know how long I walked, Gu Tie finally heard the sound of rushing water, and hurriedly quickened his pace and walked over. After turning a corner, he saw a field of starlight and water waves, and couldn't help but smile. At the outlet of the sewer is a sewage treatment plant, perhaps a former sewage treatment plant, but now a thriving lake, a pleasant vibrancy of insects and frogs under the starry night sky. Gu Tie greedily breathed in the fresh air for a while, took out his mobile phone and began to scan all kinds of animals and plants. The fatigue of the middle of the night made him thirsty and tired, and he felt that he could eat a pig and drink half a pond of water.
