It took almost an hour, Wu Yi finished exploring the first and second floors of this building, and the surviving people in the lower floors were all bronze people, Wu Yi used the correct tactics and tried to kill the bronze people with burst damage, and sure enough, he harvested a lot of metal materials and elemental crystals.

Ordinary attacks don't have much effect on the bronze man, and they will also affect the final harvest, so Wu Yi didn't summon his summon for the time being, so as not to waste energy.

Moreover, Wu Yi found that when he used the peerless sword qi, the sword qi would wrap the sword body of the giant beast's horn, and when it collided with the bronze man's steel body, the sword qi would reduce the shock of the sword body, making the damage of the giant beast's horn extremely low, and it was much more durable than the first time.

After killing more than a dozen bronze men, there were obvious damages and gaps in the horns of the giant beasts, and when Wu Yi was about to use the soul crystal to repair the long sword, the elf interrupted him.

"Sao Nian, you can try to repair weapons with gold crystals. This crystal has such a hidden effect, even if the weapon is not all made of metal, the gold element crystal can also make up for the damaged parts as much as possible, and after using it more, it can also cover the surface of the weapon with a layer of metal substance, making the weapon sharper and stronger. ”

After listening to the elf's words, Wu Yi tried to put a small gold element crystal close to the gap in the horn of the giant beast, and the crystal began to melt as if it had touched a piece of ice with a scorching flame, and then the layer of silver-white energy substance covered the horn of the giant beast, repairing the defects on it.

After Wu Yi used two gold element crystals, he repaired the horn of the giant beast to a new look. The durability reached full value again, and in between swings, Wu Yi found that the horns of the giant beast had become thicker, which was good news for Wu Yi, who had so much strength that he could lift a one-ton giant hammer, that he could use it more easily.

Seeing this result, Wu Yi's heart was relieved, it was not bad to be able to use gold element crystals to repair weapons, this is to fight to nourish war, and the weapon has been kept intact in order to kill more bronze people and obtain materials and crystals. Otherwise, if you keep using soul crystals to repair weapons. Wu Yi felt a little unaffordable.

After exploring the first and second floors, Wu Yi walked up the metal staircase again and walked towards the third floor of the building.

In the corridor on the third floor, Wu Yi saw a bronze man wandering again. He was faintly disappointed. He thought he would be able to see a new breed of enemies on the third floor.

Wu Yi stepped forward to take the lead in tracking techniques. Started the journey of abuse of the bronze man, and with the tracking technique to reduce the defense, it was much easier to deal with the bronze man. Wu Yi's next thrust easily pierced the bronze man's body, and the armor-piercing effect made the bronze man even worse and more vulnerable.

Wu Yi then used another set of swordsmanship, each sword swing was wrapped in a sword qi that made people feel cold all over the body, with the blessing of unparalleled sword qi, the power of these swordsmanship skills was much stronger than ordinary swordsmanship, majestic, so that the bronze man's body had a precursor to collapse.

But at this critical moment, there was a vicious wind coming from behind, and someone launched an attack behind Wu Yi, and listening to the sound, it was definitely a terrible blow.

Wu Yi didn't have much time to react, so he could only quickly reflexively put the horn of the giant beast across his chest, and then he was smashed into the sword by a fist of steel.

was condescendingly hit by this powerful punch on the sword body, Wu Yi felt a huge force coming, and with Wu Yi's strength, he couldn't bear it, so he had to take two steps back to block this force, and the back was also punched by the bronze man, and his internal organs were somewhat injured.

Wu Yi raised his head and found that what attacked him was an iron man with a gray and white body, this iron man was taller than the bronze man, more than two heads taller than Wu Yi, it seemed that when it was metallized, because of the different metals constituted, they would have different enormities.

Iron Man: Level 16. HP 3600, Attack 95-110, Defense 320. The body of steel, the bones of steel. Iron Fist: Iron Man's fist is made of steel and has indestructible strength, Iron Man's attack power is +20 points, and each attack will deal additional damage based on the difference in strength. Iron Fist Strike: Iron Man unleashes an iron fist that deals 200 bonus damage to the target and has a buffer of 15 seconds. Combat ability: Boss. Notes: Similar to the Iron Man, the Iron Man is made entirely of extremely hard iron, which is difficult to destroy and has stronger defense. Moreover, its soul and instinct are more intact, so the wisdom of the iron man is higher than that of the bronze man, and it also has a stronger combat awareness and ability than the bronze man.

Wu Yi didn't find any trace of the iron man in the corridor before, it seems that this guy was hiding in a room on the third floor before, and was alarmed by the sound of Wu Yi and the bronze man fighting, so he ran to the corridor, and the wisdom knew that he wanted to quietly launch a sneak attack, and gave Wu Yi a hard blow with an iron fist.

This is a situation that did not happen to Wu Yi when he dealt with the bronze man before, the wisdom of the bronze man is very low-level, and he will only stay on his own one-acre and three-point field, even if there are similar people killed in front of their eyes, they are indifferent, and they will not be attacked if they don't mess with them.

The Iron Man, on the other hand, will join the battle whenever they find an enemy, and will use their skills appropriately, and their wisdom is in stark contrast to the Bronze Man.

Interrupted by the Iron Man, Wu Yi didn't care much, he disappeared with a swift wind step, and then appeared behind the Bronze Man, slashed at the Bronze Man with a single blow, and began to charge behind it.

When Wu Yi blasted out five nail punches, the bronze man had not yet reacted, and after being hit in the back by this explosive punch, the bronze man was completely killed by Wu Yi and fell to the ground.

After killing the bronze man, Wu Yi raised his middle finger at the iron man, and the iron man actually reacted to Wu Yi's provocative action, it slapped its chest angrily, and then walked towards Wu Yi with a fierce momentum.

The wisdom of the iron man has not yet fully understood the meaning of the middle finger, but in its consciousness, it feels angry when it sees the action of being raised by someone with the middle finger, and it can't wait to tear Wu Yi apart.

Although it is taller than the bronze man, the iron man's reaction and action speed are two points faster than the bronze man, and its iron fist slammed into Wu Yi, Wu Yi also had to face it strictly, and he chose to take a hard hit.

The iron man is more than two meters tall and weighs a full ton, this punch is comparable to a heavy hammer strike when it hits, because of the quality relationship and the destructive power is quite terrifying, Wu Yi can feel that brute force when resisting, but he did not retreat this time, but his counterattack sword slashed the iron man's arm.

was repelled by the heavy blow of the iron fist before, not only because of Wu Yi's lack of preparation, but also because the iron man's punch was a skill, which was even more terrifying.

Through this confrontation, Wu Yi can realize that the strength of the iron man is completely explosive, the strength, speed, and wisdom are all superior to the other party, the iron man is no longer a role that is ravaged by others like the bronze man, Wu Yi also needs to spend some effort on dodging the opponent's attack, otherwise it will be a little unbearable to hit a few iron fists.

Looking at the iron man's 320 points of defense, Wu Yi frowned, and did not rashly launch an attack, he tried his best to avoid the iron man's attack and waited until the tracking technique was buffered.

As soon as he raised his arm, energy adhered to the iron man's body, forming an energy marker, which was the effect of the tracking technique, which directly reduced the iron man's overall defense by 100 points.

Then Wu Yi turned on the effect of the eye of the sky, which can ignore the enemy's 120 points of defense, the iron man is a leader-level enemy, and Wu Yi's combat ability is the hero level, the suppression blade makes Wu Yi can ignore the opponent's 20 points of defense, plus Wu Yi's direct stab armor-piercing effect, its defense is useless when dealing with the iron man.

After multiple weakening to deal with defense, Wu Yi had much easier time dealing with Iron Man, and he still used his previous tactics to use high-damage skills to deal with Iron Man as much as possible, without leaving too many wounds on his body, so as not to affect the quality of the loot.

After using two rounds of swordsmanship skills, combined with the unequaled sword qi, the iron man was already considered the end of the strong crossbow, and then his life was ended by Wu Yi's five-in-a-row nail fist.

Next to its corpse, in addition to the gold element crystal (small), there was also a gray-white metal block, and after Wu Yi picked it up and looked at it, he found that this metal block was fine iron.

While using gold element crystals to repair the broken gap on the horn of the giant beast, Wu Yibian asked the elf, "You said before that upgrading the Suppression Blade requires refined iron and a hundred-year-old hardwood, right?" ”

The elf nodded and replied, "Well, fine iron and hundred-year-old hardwood are the best materials for the perfect upgrade of the Suppression Blade, and if these two materials are enough, it is enough to upgrade the Suppression Blade to the bronze level." However, after upgrading to the bronze level, the Suppression Blade requires more advanced materials to upgrade, and many other equipment is also like this, and the need for materials changes as the level increases. ”

"That's good, the Iron Man will just drop fine iron, it seems that this steel creature is all stored in this steel city, and I will definitely be able to harvest enough refined iron." When I go to the Wood Elemental Gathering and collect some hundred-year-old hardwoods, I'll be able to upgrade the Suppressed Blade. Wu Yi said.

The effect of the Suppression Blade is very good, it can suppress enemies with lower combat ability than Wu Yi, inflict absolute damage while ignoring the enemy's defense, and it has a miraculous effect in the face of low-end enemies, and it is also one of the preparations that Wu Yi has made to deal with a large number of low-end enemies that may need to be faced in the ladder challenge.

Wu Yi never fights unprepared battles, he wants to successfully pass the guò ladder challenge, but with many preparations, he must definitely pass guò at one time.

Refined iron is actually a very in-demand metal material, and it is required to upgrade a variety of weapons and armor, and no matter how much you collect, it will not be wasted.

In order to harvest fine iron, Wu Yi began to clean up the iron man on the third floor, about half of the bronze men on the third floor, and the remaining half were iron men, and the iron men were often attracted by the movement of the fight, so Wu Yi was not worried about finding a target.

It took more than an hour for Wu Yi to search every space on the third floor, kill all the iron men inside, and collect about twenty pieces of fine iron. (To be continued......)
