Hu Bo also tried to go up and open the silver treasure chest, but unfortunately with his lock-picking skills, he couldn't open the silver treasure chest.

Since the master key was rewarded by Zhang Kai after obtaining the title of treasure chest hunter, it was already bound to him, and it could not be used by Hu Bo.

"Forget it, bring these chests back, and when I find a lockpicking book, I'll open them again!"

Zhang Kai directly dialed the communication, and asked Fanhua Luo to help pay attention to the auction house and help him take a book of lockpicking and the like.

Lockpicking is a skill of the thief profession, and generally only the thief profession can be learned, but there may also be a lockpicking skill book that is common to the profession, and other professions can also be learned.

However, without some of the mastery bonuses of the Rogue class, the success rate and upgrade speed of lockpicking are not as high as those of the Rogue class, and in the end, the Rogue class is the master of lockpicking.

Putting away the silver treasure chest in the room, Zhang Kai noticed that there were still a lot of rare materials in the room.

"It's ...... Fine linen, the primary material of the tailor, generally requires the junior tailor to process the linen, which requires a lot of time and energy......"

"There's a big stack here, at least fifty or sixty copies!"

Hu Bo is very clear about the materials from all walks of life, and Zhang Kai is also moved.

Fine linen is an important material for tailors, similar to fine iron blocks, they are the best materials, a tailor, it usually takes half an hour to weave a fine linen.

Due to the high energy and time consumption, fine linen is still relatively expensive in the market, and some tailors who have just been promoted to junior tailors and have not mastered the primary drawings make a living by weaving fine linen.

But even so, the consumption of fine linen is still very staggering, and the market has always been in short supply.

This room used to seem to be a warehouse-like existence, and there were three stacks of fine linen inside, adding up to more than a hundred servings!

The linen alone was a pleasant surprise, not to mention the collection of art and three bronze suits in the room.

"Put all these things away, and take the fine linen to the Tiandao grocery store, so that the tailor can make a lot of cloth armor, and those mages are not short of money......"

After cleaning up, it took some time to fight into the next room, and there were some treasure chests, treasured art, bronze suits, and materials, but this time the materials were replaced by medicinal herbs.

"Elementary herb seeds, and several intermediate herb seeds, this is ...... Seeds of the Wonder Flower! ”

Zhang Kai recognized the various medicinal herb seeds, most of which were junior and intermediate medicinal herb seeds, which could be used for Xia Zining to plant, and the rarest of them were the seeds of Qiling Flower.

Qiling Flower, the material for making intermediate potions, the most important thing is that this medicinal material can be used to make magic energy burst potions, which is a powerful potion that can increase magic strength and spell damage for a period of time, and it is the magic medicine of the mage profession.

Magic Energy Burst Potions are sold in the apothecary stores in Qingshan City, and some high-level alchemists or master-level alchemists will put up a small amount for sale.

After those NPC apothecaries were known to the players, they were simply broken down, and as soon as the magic energy burst potions on the shelves were put on the shelves, they were killed almost instantly.

However, due to the limited production of Qiling Flowers, the number of magic energy burst potions is relatively small, and Lao Wang has not grabbed a bottle of magic energy burst potions until now.

This is also related to Lao Wang's character, he likes to buy it himself, so he didn't send someone to squat, so naturally he couldn't grab such a sought-after potion.

"If the Strange Spirit Flower is planted, not to mention using it to make a magic energy burst potion, just selling it directly is a huge amount of money......

There were about thirty Strange Spirit Flower seeds in the room, which was enough to plant a wave and then collect the seeds.

The rooms in the Castle of the Dead seem to be stored with all kinds of materials, and the rooms on the second floor of the back have been opened one by one, and there are all kinds of tailoring, forging, alchemy and even alchemy materials inside, which can temporarily relieve the pressure on the Heavenly Dao Grocery Store.

"There are one hundred and fifty seeds of the Qi Ling Flower, and when the time comes, let the Zi Ning plant near the Spiritual Qi Spring, so that this medicinal herb can mature as soon as possible."

Xia Zining mentioned that the various medicinal materials planted in the medicine garden last time are about to mature again, and this time including some intermediate medicinal materials planted before, it is definitely a bumper harvest.

"There is a big boss in front, it seems that Zhang Kai has to make a move......

Hu Bo, who was exploring the road ahead, brought new news, the Musou team had cleared most of the rooms on the second floor, and beyond that was a hall, as well as a staircase leading to the third floor.

"Let's go see ......"

Zhang Kai cautiously hid to the door of the hall, and sure enough, he saw a tall gargoyle.

Obsidian: Special boss, first-order creature, level 28. The blood volume is 1.2 million.

Obsidian is made up of extremely hard obsidian, a very special material that has the function of guiding demons, and is the material used by the mage class to build magic towers.

Because of this, the obsidian goryle has extremely high magic resistance, coupled with its own defense, this boss is simply invincible and very difficult to deal with.

"It's okay, if you can hold this boss, I can consume it to death......"

Zhang Kai grinned, he took people up, Chen Xi and Le Yao changed two pieces of equipment, and their defense and blood volume have increased a lot, but they can withstand the obsidian goyle.

But the most important thing is to move the boss, Lao Wang's first-order spell fell up, and the obsidian goyle's body rose with more than thirty points of damage!

"I'm rubbing, what is this boss made of, why is it so hard, my magic is more than four hundred, and one skill can only hurt so much!"

Hu Bo, Luo Badao and others also made moves one after another, and the physical attack fell on the obsidian goyle, which also had less than twenty points of damage, and the physical defense of this boss was equally terrifying.

Moreover, obsidian goyles are made of obsidian all over their bodies, and effects like bleeding are useless to them at all, and they don't use bleeding damage against bosses.

+150！ +150！

There are two recovery effects on the boss in a row.,It actually has the attribute of automatic repair.,Restore 300 points of blood per second.,Even if you stand there and let Lao Wang and others output.,They can't kill this kind of boss.。

"What's the matter, I'm so angry, I was afraid that the output would be too fierce and the hatred would overflow, and the shield battle couldn't pull the boss, this time I output with all my strength, and this boss didn't react!"

"It feels like I'm completely mocking us, if it weren't for the level gap being too big, I wouldn't have been able to deal this little damage."

Lao Wang was thinking about it on the side, and when everyone was worried that the output was not enough, two injuries appeared on the obsidian goyle.

-98！

-1225！

Slash!

The first is pure physical damage, and the second is the splash damage of the Great Swing.

Seeing Zhang Kai's skill damage, everyone was pleasantly surprised, and his skill damage was also not reduced too much when facing obsidian!

No wonder Zhang Kai said that as long as others can drag down the boss, he will kill the obsidian goryle.

"You try your best to hold off the boss, just give me the output!"

Even if Li Taiyu made the obsidian goyle the villain, everyone's output was only a hundred, and it was still incomparable to Zhang Kai's fierce and terrifying damage.

"The obsidian goyle has entered the petrification state, and it can use the petrification potion!"
