Even though these Slave soldiers possessed extremely exaggerated Life guardian energy if thinking of their ages and also grasped a certain degree of fighting skills, but … In terms of battle-qi and magic, they were far too weak. They couldn't even be considered experts.

In fact, this wasn't just a matter of the slaves, but a very common problem. It wasn't easy to cultivate dou qi and magic power. Firstly, it was hard to cultivate dou qi and magic power, which depended on one's aptitude. Just having the opportunity to learn Dou Qi and magic was extremely rare, and not everyone had the opportunity to do so.

Soga was very clear that at the moment, using these slaves against normal seafarers was not a problem at all. However, if he used them against the various experts on the trade routes, it would simply be like serving food to them. It would take some time for others to kill them, but they were completely unable to threaten the safety of others.

Soga had tried to make thousands of slaves gang up on Xiang Yun before. Although it was very difficult for Xiang Yun to kill any one of them, these slaves could not even think of trapping Xiang Yun. Facing thousands of slaves, Xiang Yun could come and go whenever he wanted and even if Xiang Yun wanted, he could kill any one of them.

For an expert like Xiang Yun, these slaves were basically the same type as turtles. Although they had thick shells, which were hard to move, they were completely harmless, no matter how strong your defense was, as long as you didn't have the ability to attack, they wouldn't be of any use.

Soga could imagine that if these top-notch slaves were used to protect Soga City, it would be a joke. These fellows' only function was to be a shield and delay the enemy's attack for a bit. Other than this, there was nothing else they could do.

Soga wanted Xiang Yun to teach everyone some combat skills, but Xiang Yun rejected his plan on the spot. Whether it was the archery skills or the greatsword in their hands, they had played a good game and already formed their own system, the only thing that was lacking was the energy to fight. If one did not increase their combat capabilities, even if they managed to kill the enemy, they would not be able to cause any effective damage.

Facing this enormous problem, Soga couldn't help but sink into deep thought. But after thinking for a long time, Soga was completely unable to find a solution to it, as these top-notch slaves over the age of twenty had already passed the period of rapid growth of their qi and magic power. Even if they started to cultivate diligently now, they still wouldn't be able to achieve much. Aside from being able to resist blows, there was virtually nothing else that these God-level slaves could do.

After thinking for a whole week, Soga still could not come up with a solution. At the same time, Soga had already resumed trading, and occasionally, a caravan would pass by and purchase some metals to trade with elsewhere. Occasionally, a pirate would attempt to land on the battlefield, but … Under the cooperation of 200 mercenary groups, no pirate could make it to the shore!

Soga knew that in a short period of time, because Soga had just recovered and had not amassed too much wealth, it would not attract the attention of any large pirate groups, let alone the combined army of the pirates. However, Soga knew better, that there would come a day when the pirate alliance would come again.

In the next few days, Soga ordered all of the Slave soldier s to train their battle skills, especially when training their battle qi. Although it was impossible to increase it by a lot, but increasing a little bit of battle qi was always a good thing.

As for Tomy, Xiang Yun and the others, they weren't as lucky as Soga, they didn't even have a single moment of rest. Xiang Yun, Roger, led a hundred Camil grade super giant sailboats, shuttled back and forth between Soga City and the other cities, and transported the necessary supplies to Soga City. As for Tomy and her sisters, they would lead another hundred Camil grade ships, hired skilled craftsmen and slaves who had mastered mining techniques, and transported them back to Soga Island.

Originally, Soga wanted to move the city inland, but … As a port city, it was necessary to build it by the sea. If it was too close to the sea, the various costs would increase too much. It was completely unrealistic. Unless the problem of defense was completely resolved, the 200 mercenary groups would have to continue spending 400 million every month.

After pondering for many days without any conclusion, Soga finally let go of his worry and headed towards the mines alone. Although he had already become the City Lord of Soga City and the owner of over a hundred mines, Soga had never gone to the mines before.

After leaving Soga's city and travelling for a few kilometers, Soga finally arrived at the mining pit. Looking around, the so-called mining pit was actually a sky-high mine, and looking at it, it was a huge mountain range that stretched endlessly and reached into the clouds. In every corner of the mountain range, huge pits had already been dug by miners, and this was the so-called mining pit.

Up till now, the mining of metal ores was still very primitive. It was like a miner waving his pickaxe and knocking it against a mountain wall. The pieces of stone that came out were the so-called metal mines.

Because it was a metal mine, the rock was very hard and heavy, so … It was not easy to find the next piece. It was very heavy, so moving it was very difficult. Although the metal production was much higher than that of the Agate and Gem, it was still insufficient to meet the demand.

In this world, the demand for metals was very high. Carriages, ships, weapons, armors, daily necessities, almost everything needed to use metals. Thus, some people had calculated that even if the ores here were to be completely mined, they would not be able to supply social needs at all.

In addition, although these ores looked pitch-black, the truth was that these ores were of different metals depending on the layers of the ore. In addition, even a single ore contained several types of associated minerals, and these minuscule associated minerals were the rarest and most precious of metals.

All the minerals mined would be transported to a huge smelting site outside the mine pit. After smelting the ore, various metals would be produced. This was the specialty of this place — precious metals.

Looking at the backward mining pattern, Soga couldn't help but frown. In Soga's memories, there seemed to be a type of transportation-type Magic coupling. If it could be successfully created, it would at least save the workers in charge of transportation. The number of mining and transportation personnel was one to one!

After thinking about it, Soga did not continue to watch and directly turned around to return to the City Lord's Mansion. Closing the door, he took out the Magic coupling — Baal.

While thinking, Soga opened the skin of the Sand worm on Baal's body and started to study its structure. If they wanted to mass produce Baal, it would not be possible to use Baal's current structure. If it was specifically made to transport goods, many organizations could skip it.

After a few days, Soga had closed off his room, dismantling all the connections within Baal's body, and was constantly pondering about new combinations. Soga only pursued one point, and that was the power to drag others, as for the other abilities, he had completely forgotten about them.

"Bam!" Just as he was lost in his research, there was a muffled sound as the City Lord's Mansion door was suddenly kicked open. In the next moment … Nico, Roger, and Xiang Yun walked in one after another.

After looking at Soga in astonishment, Nico scratched his head in embarrassment and said: "Aiya! The young master is actually home, hehe… I thought there was no one left inside. Soga unhappily rolled his eyes and ignored her. He continued to lower his head and study the Magic coupling s on the ground.

Seeing Soga's concentrated state, Nico couldn't help but go over and say excitedly: "Wa! Young Master… You want to research Magic coupling s to help you defend the city! Hahaha… If you can reproduce a Magic coupling like the Shuguang City, then our Shuguang City would be as firm as gold! "

With a helpless sigh, Soga straightened his body, casually picked up a cloth, and wiped the dust off his hands: "I want to as well, but even though I can copy those Magic coupling, but regarding the connection between the Magic coupling and the mechanism, I just can't understand."
