As for the overall action of the mechanical dog, it is a kind of "memory wood" carved into a kind of "memory wood" with various "dog" movements, so that it can move like a dog.

In short, the process is very complex. However, this is only the initial research when it is complicated, and after the successful production, it is much easier to make it according to the template.

With their ability, as long as the materials are sufficient, one can still be made a day. Of course, if there is assistance from a factory or something, half a day is not a problem.

But then Tang Ye noticed a very critical problem, that is, to make these mechanism items, you need all kinds of strange metals.

Although there are many warehouses in Blade City, how to continue to supply them has become a problem.

Previously, these materials were mined and transported from the western part of Yunzhou, and once they were used up and then wanted to be made, they had to have a fixed source of materials.

Obviously, Tang Ye needed to send someone to find a place to mine these metal substances. Fortunately, there were people in Guan Li's group who knew a lot about these metallic materials, and with his help, it was easy to find a mining site, but it would take a while.

After that, Tang Ye asked Guan Li to take someone to repair the mechanism of Blade City first, and when the other party went out to work, he sent someone to send the pension of ten gold Lingjue to his newly settled home in the city.

Tang Ye believed that the money would further enhance the other party's loyalty to him. After all, the other party's loyalty is only 60 now, and Tang Ye needs to make some preparations to improve his loyalty.

In the next five days, while resting his army, Tang Ye began to study the next attack plan - the attack on Alchemy City.

According to Guan Li, Alchemy City is a city with various special metal mines. If they can attack it, then at least for a short time, they will have enough metal to create traps.

Of course, because of this, this city is not so easy to attack, because according to Guan Li, this city also has a large number of mechanical dogs and other mechanism items, and there is even a terrifying mechanism giant, whose strength has almost reached the fourth level.

Of course, if it's only the fourth level, it's not too much of a problem, whether it's Tang Ye or Pisley, it's enough to deal with it. The point is that this Trap Giant is not a melee combat, but a ranged movable turret.

Although the ejection is not a cannonball, it is also a variety of powerful boulders, poison barrels, and other lethal weapons.

Although Tang Ye hadn't seen it personally, he could still feel its power. After all, this mechanical dog is already so realistic and powerful, not to mention the more complicated and terrifying mechanism giant.

According to Guan Li, the giant is a few points taller than the city wall, and it also has the function of transformation, whether it is attack and defense, it is very terrifying.

Of course, mobility may be the only weakness, but even then, no one can easily do anything about it.

Tang Ye looked at the local geographical map hanging on the wall, thinking about possible ways to attack.

As the saying goes, the siege is the bottom, and the attack is the top. Now that Zheng Ting has gradually stabilized his position, it is obviously not so easy for Tang Ye to easily defeat these cities.

However, he is not particularly anxious, now that his troops are advancing in two ways, Liang Xue's side has Hou Yi's skills to help, and the attack is relatively smooth.
