The mechanical dog's limbs and back were covered with sharp blades and spikes, and it was equipped with two magic guns on its sides, and the slender tail behind it was like a scorpion's tail thorn.

This mechanical dog has a metallic luster flowing all over its body, and with the lethal weapons all over its body, it looks powerful and handsome, much more imposing than the three-headed hell dog that Haixin saw before.

The eyes made of the red crystal nucleus of the mechanical dog scanned the three of them, and those eyes were emotionless as if they wanted to see through a few people, and when it finished sweeping it, it suddenly barked at the sky, and then ran towards several people.

"Wow!!!That's cool!" Haixin was attracted by the appearance of the mechanical dog, and boys probably liked this cool look that looked violent.

"That's cool!" Leo was also amazed, and he raised his left arm and said to the Milky Way wrapped around his arm, "Galaxy!

Leo's words fell, only to see the galaxy jump from his arm, constantly deforming in the process of jumping, and when it landed, it had turned into a mechanical dog exactly like the other party, but the other party was pure black, and it was silvery-white.

"Cool!" Haixin was very relieved to see that the galaxy had also become this fully armed appearance, and he was proud of what his teammates had.

"Galaxy!up!" Leo ordered, and the mechanical dog Galaxy rushed towards the black mechanical dog.

The two mechanical dogs, one black and one silver, galloped quickly like two shadows colliding violently, they tore and attacked each other with weapons all over their bodies.

This mechanical dog is extremely unlucky today, its combat effectiveness is extremely high, if it encounters an ordinary opponent on weekdays, then its steel and iron bones and the weapons of the whole body will definitely make the opponent die no longer dead.

But today, it happened to run into the Milky Way, which is made of unknown materials, not only extremely hard, but also can be deformed at will.

The weapons that the mechanical dog has, the Galaxy also has, but it can't do any damage to the Galaxy, its fangs and blades, and even the magic guns on both sides of its body can't do anything with the Galaxy, and every attack of the Galaxy can pierce its skin.

After a while, the black mechanical dog's whole body was already in tatters, all of which were notched by the Milky Way's fangs and sharp blades, but the whole body of the Milky Way was still so silvery smooth that there was not even a single scratch.

The black mechanical dog seemed to know that it had met its nemesis, it cowered and turned around to escape, how could the galaxy let it go, only to see the galaxy suddenly run up, the tail behind it suddenly became longer, and the spike pierced into the opponent's ass.

Then, it pulled hard and jumped on the opponent's back, and the galaxy opened its mouth and aimed at the opponent's neck and bit it down violently.

This bite was so powerful that it bit off its head, and the black mechanical dog lost its head as if it had lost power, and its huge body suddenly collapsed on the ground, becoming a pile of motionless broken copper and iron.

Watching the spike on the galaxy's tail pull out from the middle of the black mechanical dog's buttocks, Haixin suddenly felt the chrysanthemum tighten, he never thought that the galaxy still had this hobby, and a bad chill rose to his heart.

Haixin smiled and hurriedly leaned up to stroke the galaxy's head, thinking that he would hurry up and please it now, so as not to offend it in the future......

After such a small twist and turn, the three of them came to the main tower gate, opened the tower door, and a huge circular magic array was running inside, "How do you close it? Leave it to you two!" Hai Xin said.

Hai Xin can see the flow of elemental magic power of the magic array, but he can only draw a scoop according to the gourd, and let him draw a few magic arrays, which is really handy, but when it comes to the theoretical knowledge of the magic array, he is not as proficient as those alchemists who specialize in studying magic arrays.

Moreover, the power magic array in front of him was even more complex magic array that he had never seen or heard of, and the cumbersome runes and deeds were no less than any magic array in the Star Shine Palace.

Therefore, this kind of professional problem should be left to Sisan and Leo, the two alchemists, to figure it out.

"Do you want to destroy it directly with an attack?" Although Haixin didn't understand, he said a simple and direct method.

Leo looked at this complex magic array and frowned, "Stupid! It's not that simple, ordinary magic circles can, but this one can't, it is one with these seven towers, if you destroy them directly, these towers will collapse, and then I'm afraid even the castle will collapse." ”

"Yes, I originally thought that this underground magic crystal library was just a simple power array, but I didn't expect it to be this kind of symbiotic magic circle that coexists with the building. Qian Shan also responded at this time.

"It's so complicated......" Haixin was speechless.

The difference between professional and half-tone is so obvious, Haixin was stunned next to him because he didn't understand what Leo and Qianshan said about "inner magic ring", "outer magic ring", "magic introduction", "prayer" and so on What these professional terms mean, if you don't understand, you just don't think about it, Haixin concentrates on guarding them on the side.

After some research and discussion, Leo and the two took action, only to see Leo drawing various magic runes in the magic circle, while Sisan took out some magic beast crystal nuclei and placed them in a specific position, after the two of them pounded, the originally faint magic circle suddenly shone up.

"It's done!" Leo shouted, quickly taking Haixin's hand and running to the wall with Sissan.

The circle flashed a light and then spun at high speed, and in the process of spinning, magic runes flew out of the circle, and these magic runes danced happily and comfortably in the air like birds that had escaped from their cages, as if they were venting their long-lost freedom in this way.

When all the magic runes flew out of the magic circle, the magic circle and the runes dissipated at the same time, and there was nothing in front of them at this time, the previous magic circle and crystal nucleus seemed to have never appeared, and only the three people of Haixin were left in the huge tower to look at each other.

"Is this what it is?" Haixin asked suspiciously, he thought it was too simple to do nothing, right?

"What else do you want?" Leo rolled his eyes......

"Haixin, giggles, do you think it's easy to crack?" Qian Shan laughed as she looked at Haixin and Leo.

She continued: "You see that our cracking process is only ten minutes, but if you don't know how to crack the method, it will give you ten or eight years and you won't be able to complete it, even if she is a magic alchemist, Juli Peiya, she probably can't crack it." ”

"But fortunately, Leo is here today, he taught me how to crack it, this kind of symbiosis circle is the first time I have encountered it, or Leo is very knowledgeable, he actually knows how to derive a new circle on the basis of the symbiosis circle to crack the symbiosis, but this is really not something that ordinary people can do......"

Sisan even looked at Leo with some admiration, she had to look at Leo with admiration, and she also began to guess what the identity of this arrogant boy was.

When the three of them were overjoyed and wanted to leave, a low, deep mechanical voice suddenly sounded in the tower: "God!!Why are you doing this to me!!I am only one !!step away from this last step!

The three Haixin who walked to the door were startled by the sudden sound, and they quickly turned around and looked at the place where the sound came from in the tower......
