At this time, the only enemy in this underground world was this Lich Earl. After seeing the main force was destroyed, Lord Elisif was also a little panicked, and he also found some colleagues from the Khanlok Empire to plead for mercy.

But obviously the Lich City Lord's interpersonal relationship was not very good. Except for Torkenya, who was also an earl of the Empire, who sent a team of flying soldiers to come, one of the city lords' confidants chatted with Li Ran for a while and left, the others were just symbolically sent someone to send a letter.

Regarding these people and letters, Li Ran personally led Dorik to entertain them cordially and expressed his position. He had just come here to attack Lord Ken who captured his territory for no reason, but encountered a malicious attack from Count Earl Elysif. He had a battle with him out of self-defense, and he suffered heavy casualties. So now he must find this count to argue. As for the letters sent by the city lord, Li Ran also asked Dorik to give a very tactful and polite reply.

No one will go to truly offend a new baron who can defeat the army of Count and two fiefs because of a lich who has to worry about it, not to mention that this baron is still on the moral side.

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

It is said that the name of this city was named after the undead lich's name, but a few days later, Li Ran renamed it to Lisette City. As for why this name was given, Li Ran only said that if the city lord named the city name like this, only those like Lisette who could sacrifice soul fire for their companions could receive such an honor. As for why the word "Te" is added, it is just because it was the name of the immortal banshee who had become his personal bodyguard during his lifetime.

Although this brutal siege war suffered heavy losses because of the Earl Earl Elf's continuous reinforcement of the city's defense system for many years, and after five days of continuous combat, Li Ran's side, who had superior troops, finally won the victory. Before the empire's envoy arrived, Li Ran personally killed the Lich City Lord with one sword.

Standing at the place where the Lich City Lord was killed, on the platform above the Undead Castle, looking at the inner city alone, the outer city has reached nearly ten square kilometers, and the outer city has expanded several times the area. All the teammates, including Li Ran, couldn't help but take a deep breath.

This is the first mid-level city they obtained. As for the surrounding minerals, there are as many as sixteen known. In addition to ordinary iron ore, refined iron and tungsten steel, there are five of them among the rare minerals, including a mitsilver mine, a mercury mine, two red crystal mines and a sapphire mine.

However, what surprised Li Ran and others the most was another thing. On that day, they found a pile of wood with strange fragrance after opening the warehouse. By asking other lichs who were surrendered, Li Ran learned that these woods were called black brown fragrant wood, which is a rare wood that can be preserved for a long time.

Moreover, the longer this wood is stored, in addition to the stronger the fragrance, it can also obtain certain magic protection by absorbing the dark power in the elements. It is a precious wood that can be placed at home to add fragrance, make jewelry or plate armor to increase equipment protection ability, and make statues to preserve for a long time. It is also one of the most valuable specialties in this underground world. When the Lich City Lord Elisif built the city here, the main reason was that he discovered this specialty place.

After taking people to see this black brown fragrant wood forest, and using the hand of the undead lich to learn about the amount of mining available for this precious forest, Li Ran specifically instructed Duan Bo for the first specialty he obtained on the battle map to establish a barracks after he left, and at the same time, he should strengthen the technology of the mining personnel to maximize its utilization rate.

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

For most of the time, Li Ran concentrated the main content of the meeting on the entrance to the surface world. Through these days, Li Ran and the others also knew that this middle-level city in the undead, and the entrance to the surface world was between a nearby mountain range. It was another bridge connecting this underground world and the surface world.

Outside the exit of this surface world, it corresponds to a location in the continuous Leicester Mountains. What made Li Ran most worried was that there was also a mid-level city less than 100 kilometers at the entrance, and the city lord was the elves Earl Erindir, who was known as the Pearl of Leicester 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 path, this does not affect its threat to the underground world. After all, the minerals in the underground world are relatively richer than those in the surface world, especially in metal ores that can make armor and weapons. The underground world has unique advantages.

Any city that wants to develop a strong city naturally has more minerals in metals, the better. So just in case, for this Earl Erindir, who is known as the Pearl of Leicester, the relevant reconnaissance and defense work must be done in advance, otherwise the territory he has captured through great hardships will be cheaper if the Count is cheaper.

Especially now that there is a specialty here, this kind of defense is even more necessary. Black brown fragrant wood can absorb the dark power in the elements and purify the characteristics of the environment. It is undoubtedly very attractive to the surface elves who are born to hate darkness and chaos. Earl Earl Elf has such a specialty, and I believe it is not a secret among the city lords of the empire, so this defense has become the key to the key issues raised by Li Ran at this meeting.

Fortunately, his city of Thun is almost completed, and then a small teleportation array can be built to the affiliated territory.

Although using this teleportation array will cause high cost consumption, and due to space limitations, it is impossible to transmit too many personnel and troops every day, if there is an emergency, the relevant important personnel can rush over as soon as possible. Therefore, Li Ran would also ask Duan Bo and others to take over here and send the relevant materials and materials used for construction to the City of Thun as soon as possible.
