In the Sacred City, Lin Han took the ghoul materials he got from the Zhang family this time and sold them to the merchants, in exchange for more than a thousand gold coins.

At the same time, what made Lin Han more interested was the material collected by the ghoul king, the flawless ink jade.

This is a gem with magical powers, and if you find a good alchemist, you can make it into a prop that can be inlaid, which is one of the most practical ways to improve your strength in the early days.

Lin Han observed the buildings of the Sanctuary City, the town hall was about to be upgraded immediately, and the next step was the construction of the monastery and the wolf cavalry barracks.

With the upgrading of the town hall, the speed of immigration will also be accelerated, and with sufficient manpower, it can be expected that the construction speed will also be correspondingly faster, and the space of the entire Sanctuary City will gradually expand.

When the construction of the third-level town hall is completed and the space is large to a certain extent, Lin Han will also consider building a large city wall, some people may think that this is a copy space, and the city wall is also needed?

In fact, although Lin Han didn't get the heart of the castle at the beginning, he also clearly watched the battles of the owners of the heart of the castle a few times.

Whether it is a player or a local force in the Divine Grace Continent, they can all apply to Mars, the god of war, to obtain the right to enter the heart space of the castle within 12 hours and attack it.

Once the town hall is destroyed during the siege, it means that the castle where the heart of the castle was born will be destroyed.

All the hard work of the players will also be wasted.

In the previous life, there were hundreds of castle hearts that were destroyed because of the destruction of the city, and in Lin Han's memory, after level 20, after the player forces established a mercenary group, they could apply to attack players with castle hearts.

Winner, of course, will not be without benefits.

Destroy a castle and the winner will have a chance to get the gold and materials of the castle building at a discount, but more importantly, a chance to get rare architectural blueprints for the castle!

In the city in the sky, Lin Han came to the downtown area, found the jewelry store here, and walked by the dazzling jewelry counter, Lin Han found the inlay master here.

"Flawless black jade? It's a high-quality gemstone. "The master mosaic is an old man in a gray robe, a peaked hat, and a one-eyed magnifying glass.

After hearing Lin Han's request, he shook his head slightly: "I would love to be able to carve it into a usable inlay gemstone for you, but recently my carving knife has disappeared, and I can't help you without the tools at hand." ”

"But, adventurer, maybe you can get me a carved knife for a reminiscent taste?" The mosaic master looked at Lin Han and issued a task.

"The Vanishing Carving Knife, the only rare quest, retrieve the tool for the Master Tescher in the Sky City, and restore the gems in the Sky City Market, the task reward: You can get the friendship of the Master Jeweler, and get a chance to carve gems for free."

"Please note that this is the only mission, it is difficult and time-limited, so you need to be cautious when accepting it."

"The only rare quest?" Lin Han was slightly stunned, and quickly came back to his senses, it seems that this should be the first player to have the original stone, and the task will be triggered, but the grade is rare, and it is no wonder that Lin Han didn't pay attention to it at the beginning.

However, as long as there is a unique word, this rare quest will not be so simple!

Lin Han took it and soon began to run around the city in the sky from the task prompt.

First asked a few neighborhood aunts, and then rescued a beggar, followed by chasing a wild dog, it took more than an hour to go back and forth, and finally stood at the entrance of the underground tunnel in the eastern part of the sky city, and felt the breath of the monster.

"Ding, quest hint...... The traces of the carving knife are likely to be in this underground tunnel, but this is an abandoned tunnel, and it is rumored to be inhabited by many evil nezumi and fallen criminals, so please be very careful! ”

Lin Han hadn't played this dungeon, when he first came to Sky City, the players were almost level 19-20, and the underground tunnels had already been cleaned up, so he didn't have anything to do.

Out of caution, Lin Han cast a latent technique and began to touch into the tunnel.

There is no light in the tunnel, it is almost pitch black, and players with poor night vision will suffer in the environment here.

Fortunately, as an assassin, Lin Han's ability to see in the dark was not as strong as that on the ground, but he could also see about 30 meters ahead.

"It stinks......"

Lin Han smelled the rancid smell, shook his head, and continued to walk forward for more than ten meters, before he suddenly stopped and heard the sound of rapid running in front of him.

"Whew, whew!"

A barbarian warrior holding a torch and panting and running quickly appeared in front of Lin Han's eyes, he was covered in blood, and the axe in his hand was even more stained with blood, but it could be seen from his somewhat flustered eyes that he ...... Quite frightened of the pursuers behind him.

Seeing this barbarian warrior, Lin Han took the initiative to show his figure.

"It's you! Dear adventurers! Seeing Lin Han, the barbarian warrior first nervously clenched the axe and raised it in the air, and when he saw it clearly, he breathed a sigh of relief and said happily: "You must be my lucky star, at this critical juncture, I met you again!" ”

This barbarian warrior is the barbarian Gru of the War Eagle Mercenary Regiment, a local native at the level of deputy captain, and not long ago, he was rescued by Lin Han from the mouth of the demon wolf.

Because of the existence of friendly relations, the barbarian Gru treats Lin Han like a friend.

Soon, Lin Han learned about the situation of this underground tunnel from the mouth of this barbarian Gru, it turned out that their War Eagle Mercenary Regiment accepted the commission of the administrative officer of Sky City, and came to find out how many monsters were located in the underground tunnel that no one had come to for a long time, and they successfully discovered the lair of these monsters, but they soon met a rat warlock who changed their color.

According to Barbarian Gru, the 20-level lord mutated nezumi warlock was not proficient in demon summoning techniques, but also powerful dark spells, so that the five subordinates who were with him fell into the rat swarm and could not escape.

Lin Han got the map they explored from the barbarian Gru, and took this corresponding rare quest with him.

"Wipe out the monsters of the entire underground tunnel and destroy the mutated nezumi warlocks!"

This task level requires more than 15 levels, and it comes from the administrative officer of Sky City, after completion, you can get the favor of the War Eagle Mercenary Group and Sky City, and there are more honorary rewards, of course, more experience points, which is very helpful for Lin Han's upgrade.

But......

Judging from the intelligence,The monsters in this are generally level 18 or above.,And most of them are dark damage.,To deal with them,It's best to prepare the corresponding props first.。

Walking back to the ground with the barbarian Gru, Lin Han thought about it, exhaled the metal young dragon Xiaoyin, and went to the Dry Bone Wasteland, a level 20 leveling point near Sky City.
