Faith swooped down on the dragonfly, the spear in his hand let out a sharp whistling sound, and the tip of the spear emitted a strong white light, stabbing straight at the mechanical giant below.

"The target is close, lock" The mechanical giant's gaze locked on Feith, and a beam of light shot towards Feith, Feith suddenly lowered his body, dodged the mechanical giant's blow, and the spear in his hand conjured countless lights and shadows, and with a bang, attacked the mechanical giant's body. There was a clash of metal and a twisted grinding sound, and the knight's spear in Feith's hand pierced the mechanical giant's chest.

The surge of force from the knight's spear caused the mechanical giant to take a few steps back, and the mechanical giant stopped, suddenly reaching out and grabbing Faith, his eyes flashing red.

Boom, the mechanical giant fired a beam bomb and bombarded Feith's body, and the powerful air wave generated by the explosion blew Feith upside down, and a damage value of 15,000 points floated up from Feith's head.

The mechanical giant was also knocked back several steps by this wave of air.

"Faith, get out of here." Xiao Yu snorted coldly, Fei Si's blood was running out, and he couldn't withstand the blow of the mechanical giant anymore.

Xiao Yu's eyes kept paying attention to the mechanical giant, and when the mechanical giant burst out of the beam bomb, a strange light flashed behind the mechanical giant.

"Howl, the center of the mechanical giant's head three inches behind, attack!" Xiao Yu snorted coldly, and when he heard Xiao Yu's voice, Hal's body suddenly disappeared, and the next moment he appeared behind the mechanical giant, jumping high, and the dagger in his hand stabbed down on the back of the mechanical giant's head.

The Mechanical Giant didn't look back, didn't even make any defensive moves against Hal, and in its automaton, it wouldn't be the first to attack any Nads.

Poof, the dagger in Howl's right hand pierced into a soft place, and his heart suddenly jumped, this is the energy core of the mechanical giant, I don't know how Xiao Yu found out, Hal finally had a trace of emotion in his calm and indifferent expression, and for the first time he had some respect for this human being.

The mechanical giant let out a roar of rage, but after the energy core was hit, its body was extremely stiff, and it became very difficult to even move it, the energy core behind the head gradually cracked, and a strong current flowed through the mechanical giant's body, flashing on the surface of the mechanical giant's body, making a sizzling sound, just for a moment, the joints of the mechanical giant stopped moving, and thick black smoke came out.

After destroying the energy core, Hal retreated.

"There's six thousand blood left, I can't move, and I don't have a protective shield." Xiao Yu looked at the mechanical giant in front of him, his eyes lit up, this mechanical giant is no different from a bunch of experience, this is a free experience meal!

Faith had already recovered his health in the far clearing, Xiao Yu let Hal step aside, and he went up to attack the mechanical giant, the dagger waved, and the damage value floated up from the mechanical giant's head, and the parts on the mechanical giant's body continued to fall down.

Thirty seconds later, the mechanical giant's health cleared, and its massive body collapsed into fragments.

"What metal are these mechanical giants made of?" Xiao Yu asked, looking at the metal all over the ground, Xiao Yu wondered if he should move some back, maybe he could sell it for some money.

"Except for the protective shell of the energy core, everything else is ordinary steel and metal, and the energy shell was destroyed when it exploded." Hal said.

After hearing Hal's words, Xiao Yu lost interest in these metals, and fiddled with them with great interest.

"I don't know if there's anything good." The mechanical giant is a level 20 strengthening elite, and if he doesn't have something, it's really a bit unreasonable, Xiao Yu rummaged through a pile of scrap metal, and finally, dug out a recipe, an unusually colored piece of metal, and a strange sword hilt from these scrap metals.

"It's the recipe for blind grass! Sure enough, it was here. Xiao Yu thought excitedly, this blindness poison is a weapon to kill enemies on the battlefield, and he will definitely collect some blindness grass and keep it for later use, as for the other metal and sword hilt, Xiao Yu checked the properties of these two things.

Nickel-cadmium alloy: grade, treasure first-order. Forged materials.

T-Ye Low-Level Energy Sword: Grade, Legendary Grade. Attack 129-137, Attack Speed +12, Ignore Armor Type, 5% chance to Pierce. Comes with skills, Holy Sword Slash, skill base damage 120, knockback effect.

"Rich." A thought flashed in Xiao Yu's mind, this nickel-cadmium alloy Xiao Yu didn't know what it was, how much it was worth, thinking that the first-order materials of the treasure would not be too bad, and this low-level energy sword was definitely a valuable good thing.

Xiao Yu held the hilt of the energy sword, pressed it on the button of the hilt, and a beam of light grew out of the front end of the hilt, which was about the same as the energy sword used by the mecha, and slashed a small tree next to him with the energy sword in his hand, and the small tree collapsed, and the cut cut by the energy sword was unusually smooth.

Xiao Yu pressed the button again, and the energy sword automatically shrank back, leaving only a section of the hilt of the length of the dagger.

"What should I do with this thing? Sell? Xiao Yu thought about it, it was too cost-effective to sell it, not to mention that he didn't have to make money by selling equipment now, it was better to go to the market to exchange for some thieves' equipment, and if he was lucky, he might even encounter a thief's legendary items.

Xiao Yu put away the nickel-cadmium alloy and energy sword, and glanced at the experience points, 79% at level 23, after killing this mechanical giant, Xiao Yu gained a lot of experience points.

When Faith had replied, he walked over to this side.

Xiao Yu greeted Faith and Hal and said, "Let's go." ”

Xiao Yu asked the robot puppet to lead the way in front, and by the way, let the robot puppet look for the blind grass, and after searching for about half an hour, Xiao Yu counted the number of blind grass harvested, there were as many as fifteen, and the blindness potion made by one blind grass could be used five times, which was definitely enough in a short time.

"Didi, energy warning" The red light on the mechanical figure's right arm flashed a few times.

"What's going on?" Xiao Yu asked suspiciously.

"The mechanical puppet doesn't have enough energy." Hal said.

Xiao Yu was stunned for a moment, it was absolutely impossible for the mastermind to let Xiao Yu take something as perverted as a mechanical puppet out of the copy, this mechanical puppet would definitely be destroyed or scrapped in the end, it seemed that it was scrapped in a way that ran out of energy, which was better than being destroyed, at least it was retained.

"What does this mechanical puppet use for energy?"

"It's also an energy core, but it's a C-type energy core, which is different from the energy core used by the mechanical giants." Hal explained, pointing to the mechanical puppet's abdomen and saying, "The mechanical puppet's power core is contained here, as long as you find a C-type energy core, you can use it again." ”

"C-type energy core, is there very little of this?" Xiao Yu asked.

"The C-type energy core is a micro energy core, which was commonly used by us when the Nader people's technological civilization was at its peak, but now, I'm afraid that this thing can only be found in some dusty ruins." Hal said.

Xiao Yu nodded, since he couldn't find the C-type energy core, Xiao Yu was not reluctant, after all, Xiao Yu couldn't always rely on the mechanical puppet, under the guidance of the mechanical puppet, Xiao Yu had already mastered the trick of attacking and dodging in the quasi-position theory, as long as he practiced a little, even if he left the mechanical puppet, Xiao Yu could complete it well.

"How long will the robot doll last?"

"Three hours."

"Three hours?" Xiao Yu suddenly realized something, this is a signal! He can't waste any more time, he must arrive at the designated place within three hours, otherwise the robot will run out of energy and the mission will fail! If Xiao Yu wants to complete the task, he must be inseparable from the guidance of the mechanical puppet, which is Xiao Yu's intuition and Xiao Yu's sensitive judgment of the task.

"Once the alarm is generated, the mechanical puppet will only be able to sustain energy for three hours." Hal glanced at Xiao Yu with some confusion, Xiao Yu's expression was very solemn, this mechanical puppet's energy exhaustion is not a big deal!

The thinking of the task executor and the thinking of the NPC are completely different, and the task executor can not only complete the task by substituting the plot like the NPC, but also jump out and judge the direction of the task in an objective way.

"Let's go, we can't delay any longer." Xiao Yu said to Faith and Hal that Xiao Yu had delayed a lot of time when he came, and the task time was very tight, and it was probably too late!

"Yes." Faith and Hal were puzzled, why was Xiao Yu suddenly in such a hurry, could something terrible happen?

"Follow me." Hal said, leading Faith and Xiao Yu towards the entrance of the underground city, copying a path, a shortcut, and avoiding most of the guards.

After knowing that the task was urgent, Xiao Yu didn't delay any longer, and when he encountered a monster, he asked Faith and Hal to rush up and kill them directly, and they rushed all the way to the entrance of the underground city.

"We have to be careful after entering the dungeon, there are a lot of powerful guards inside, we have to avoid them as much as possible, I have a shortcut to the highest level of the dungeon." Hal said, taking Xiao Yu and Faith into the elevator.

Sure enough, entering the underground city really needs a traitor to lead the way, Xiao Yu said in his heart, took the elevator to the fifth floor, Xiao Yu poked his head into the aisle, and faced six black-clothed priests walking towards this side, Xiao Yu was startled, the six black-clothed priests, if they found out, they would have to retract again.

Xiao Yu and the others hid for a while, and the six black-clothed priests walked away from afar, and Xiao Yu and the others dared to come out.

Xiao Yu entered the stealth state, groped forward, threw a bottle of invisible potion to Fei Si, and told him how to use it, in case of emergency, fortunately, Fei Si is a soul body, and if he enters the hidden state, it is difficult for ordinary people to find out.
