At this time, the enemy of this underground world was the only one left with the Lich Count, and after seeing the main army destroyed with his own eyes, this Lord Elysiphus was also a little panicked, and for this reason, he also found some colleagues in the Khan Rock Empire to intercede.

But apparently the relationship between this lich city lord is not very good, and the few city lords found, except for one of them, Torkenya, who is also an imperial earl, sent a team of flying soldiers, and one of the city lord's cronies chatted with Li Ran for a while before leaving, and the others only sent a letter in a symbolic sense.

For these people and letters, the former Li Ran personally led Doric to entertain them cordially, and made his position clear, he had only come here to attack a Lord Ken who had captured his territory for no reason, but he encountered a malicious attack from Earl Elixifer, and had a battle with him out of self-defense, and he suffered heavy casualties, so now he must find this earl to reason, as for the letters sent by those city lords, Li Ran also let Doric give a rather tactful and polite reply.

No one would really offend a new baron who can defeat both the Earl's army and two fiefdom lords because of a sloppy Lich Count, let alone a baron who is still on the moral side.

So half a month later, Li Ran's army personally led the army and arrived at the center of this underground world, the undead mid-level city of Angels.

It is said that the name of this city is named after the undead lich during his lifetime, but a few days later, Li Ran renamed it Lisette City, and as for why it was named, Li Ran only said one sentence, if the previous city lord named the city name like this, then only a person like Lisey, who can sacrifice the soul fire for his companions, can obtain such an honor, as for why a special word was added, just because it was the name of the undead banshee who had become his personal guard.

Although this brutal siege war was caused by the heavy losses caused by the Earl of Elisifer's years of continuous reinforcement of the city's defenses, and after five days of continuous fighting, in the end, Li Ran's side with superior forces won the victory, and before the imperial envoys arrived, Li Ran personally killed the lich city lord with a single sword.

At this moment, standing in the place where the Lich City Lord was killed, on the platform above the castle of the undead, looking at the inner city alone reaching nearly ten square kilometers, and the outer city is a middle-level city that has expanded several times the area, including Li Ran, all the teammates couldn't help but take a deep breath.

This is the first mid-tier city they have obtained, and there are as many as sixteen known minerals around, in addition to ordinary iron ore, refined iron and tungsten steel, among which there are five rare minerals, which are a mythril mine, a mercury mine, two red crystal mines and a sapphire mine.

However, the most surprising thing for Li Ran and the others was another thing, this day they opened the warehouse and found a pile of wood with a strange fragrance, and by asking the other witches who had been surrendered, Li Ran learned that these woods were called black and brown fragrant wood, which is a rare wood that can be preserved for a long time.

And the longer this wood is stored, in addition to the stronger the fragrance, it can also obtain a certain magical protection ability by absorbing the dark power in the elements, it is a kind of precious wood that can be placed at home to add fragrance, made into jewelry or plate armor can increase the protection ability of equipment, and made into statues can be preserved for a long time, and it is also one of the most valuable specialties in this underground world, and the main reason why the Lich City Lord Alicephus built the city here was because he discovered this specialty.

After taking people to see this black and brown fragrant wood forest, and at the same time learning about the amount of mining available for this precious forest through the hands of the undead lich, Li Ran specially told Duan Bo to set up a barracks base here after he left, and at the same time to strengthen the skills of the mining personnel to maximize their utilization.

After a few days of inspection, Li Ran convened a meeting with everyone that night, and after first asking Duan Bo and them to focus on protecting this special area, he made certain requirements for the mining of other minerals.

And for most of the next time, Li Ran focused the main meeting on the entrance to the surface world, through these days of understanding, Li Ran and they also knew at this time that this city is located in the middle level of the undead, and the entrance to the surface world is between a nearby mountain range, which is another bridge connecting this underground world and the surface world.

And outside the exit of this surface world, it corresponds to a location in the continuous Leices Mountains, and what worries Li Ran the most is that less than a hundred kilometers away from this entrance, there is also a middle-level city, and this city lord is still the elf Earl Erlindil, who has the reputation of the pearl of Leices in the empire.

Although elves are not a race that likes to fight, and the underground world will not be an obstacle to their development, this does not affect their threat to the underground world, after all, the minerals of the underground world are relatively rich compared to the surface world, especially in terms of metal ores that can make armor and weapons, the underground world has a unique advantage.

And any city that wants to develop a strong city, the more minerals in the metal area, the better, so just in case, for this Earl of Erlindil, who has the reputation of the Pearl of Leices, the relevant reconnaissance and prevention work must be done in advance, otherwise the territory that he has worked so hard to fight will be a big loss if the earl is cheaper.

Especially now that a special product has been discovered, this kind of precaution work must be put in place, the black and brown fragrant wood can absorb the dark power of the elements, and can purify the characteristics of the environment, which is undoubtedly very attractive to the surface elves who are born with hatred of darkness and chaos, and Count Elixifer has such a specialty, I believe it is not a secret among the city lords of the empire, so this kind of precaution has become the key to the question raised by Li Ran in this meeting.

Fortunately, his city of Thun is almost complete, and it is time to build a small teleportation array to the dependent territory.

Although the use of this teleportation array will produce high cost consumption, and due to the limitation of space, it is impossible to transmit too many personnel and troops every day, but if there is an emergency, the relevant important personnel can rush over as soon as possible, so Li Ran will let Duan Bo and the others hurry up and take over here, and send the materials and materials used in the relevant construction to the city of Thun as soon as possible.
