Ada's diary has been written until June 30, and the diary that Yan Fei found in the study before is also Ada's, and the date on it is from July 1.

So in this way, there is a chance that the key is in the room of Brother Jem's mouth in Ada's mouth!

And in this corridor, there is only one room for the man, Yan Fei took the women to the door of the fifth room, pushed the door open again, and another monster appeared in front of everyone.

Jem (Modified), the test subject of the successful transformation of the alchemist Santanis. Level 59, a silver-level boss monster. HP 150000, mana 75000, high physical attack, medium spell attack, high physical defense, medium spell defense. Skills: 1. Crazy bite. 2. Charge. 3. Claw strike. 4. Trampling. Special Ability: Beastification. Special monsters, untamable.

It's another monster like Mary, except that this Jem is a half-horse man who was pieced together with a horse!

Under the concerted efforts of Yan Fei's team, the boss fell to the ground again, and Yan Fei finally successfully obtained a key, grandma's, can finally leave this broken place, Yan Fei couldn't wait to open the door at the end of the corridor......

Behind the door was an empty hall, and there was only a huge laboratory table in the hall, on which were some bottles and jars, and the containers contained potions of various colors, it seemed that this was the alchemist Santannis's own laboratory!

There's a door in the hall that leads to the basement, but it's locked again, Nima! You won't be looking for the key again, will you? Yan Fei leaned over to the experimental table and rummaged through it.

In addition to bottles and cans on the table, there were also a bunch of drawings, Yan Fei picked up a stack of drawings, but unexpectedly a page of notes fell out of the drawings, Yan Fei picked up the page of notes in surprise and looked at it.

Santanis's alchemy notes: I am the great alchemist Santanis, today I have finally completed the self-transformation, have an invincible body, and no one will be able to kill me again, hahahaha!

Why am I so sleepy? Could it be that the body has just completed the transformation and has not been able to adapt to it? It must be so, I need to rest, I need time to get used to this body.

Damn it! Who touched my potion? Didn't you know that alchemists' potions all have their own imprints? No matter who touches my potion, I won't let you go!

Damn Ada! Why is it a gray potion? Why do you want to smash the gray potion? It's an unforgivable sin! Even if you were my servant, I would not spare you!

Damn it! Something seems to be wrong with my body, no, I need to rest, rest......

Seeing this, Yan Fei finally understood what happened, obviously Ada is Santannis's loyal servant, but Santannis's temperament has changed greatly after self-transformation, Ada just accidentally broke a bottle of potion, which angered his master and transformed him into a monster, Ada is really a pathetic person.

Now that he knew the whole story, Yan Fei clapped his hands and gathered all the women together, and then smashed the medicine bottle on the table very casually, and then the whole hall shook, and a behemoth rushed out from behind the door.

"Who is it? Who's moving my potion! Manic voices echoed throughout the hall, and a giant polygonal worm appeared in front of everyone! And the head of this giant polygonal insect is a human head!

Santanis (Transformation), the perfect modification of the alchemist Santanis. Level 60, a gold-level boss monster. 300,000 HP, 150,000 mana, high physical attack, high spell attack, high physical defense, high spell defense. Skills: 1. Crazy bite. 2. Charge. 3. Trampling. 4. Venom spraying. 5. Guided rejuvenation. Special Ability: Shield Wall. Special monsters, untamable.

Nima! The legendary mad alchemist Santanis has finally appeared!

Don't say a word, just start fighting! Su Qian pulled the blame, Lin Weiwei treated, and the rest of the people were all output.

Santanis's attack and defense are very perverted, Su Qian's pressure has doubled, but fortunately, with Lin Weiwei and Liu Yun helping to treat, Su Qian barely resisted the boss's attack.

The boss has 300,000 health points, and everyone is very lucky, but as long as the boss's trampling skills are interrupted, Su Qian can steadily hold the boss's hatred, and then we must pay attention to the boss's guiding rejuvenation technique.

Sure enough, when the boss's HP dropped to half, this thing began to use the Guided Rejuvenation Technique to heal himself, how could Yan Fei let him recover his HP? The telekinesis that had been prepared for a long time was unleashed, interrupting the boss's recovery skill.

Guided Rejuvenation is not an instantaneous skill and can naturally be interrupted. After being interrupted three times in a row, the boss went berserk and began to spray venom!

Everyone's blood volume dropped rapidly, and at this time, Lin Weiwei turned on the group healing skill, and the drop speed of everyone's blood volume stopped.

"Boost your output! Use all your explosive skills! Yan Fei frowned, and hurriedly ordered.

So everyone bombarded wildly, hitting huge damage values one after another, and everyone's blood volume rose again!

You must know that Su Qian has always had a blood aura, as long as the damage value you cause is high, the health value you recover will be more!

Seeing that the boss's health was constantly consumed, it finally dropped to one-tenth, and at this time, the boss's head and hands and feet suddenly shrank together, leaving only a huge carapace lying quietly on the ground!

MISS,MISS,MISS......

The attack of the crowd played a bunch of MISS symbols on the boss, damn! The boss has opened the shield wall! While the shield wall is in place, all attacks are ineffective against it!

After the BOSS opened the shield wall, he immediately used the guided rejuvenation technique, Yan Fei was dumbfounded, can he still do this? You're a level 60 gold boss, too shameless, right?

No matter how much Yan Fei scolded, it was useless, and the boss's HP returned to more than half! I'll go, the first half of the day, in vain!

As soon as the time of the BOSS shield wall passed, everyone bombarded the boss again, and the boss's HP dropped to one-tenth again, and it used the shield wall skill, and then guided the rejuvenation technique......

Seeing that the boss's blood volume was restored again, Yan Fei fell into deep thought, Nima! If you continue to fight like this, sooner or later you and the others will be consumed here!

Is there any way to stop the boss from regenerating? Yan Fei thought hard, any skill is ineffective against the boss who opened the shield wall, and there is no way to stop it from using the recovery skill?

Draining its mana? No way! 150,000 mana is there, even if you and others are consumed, you may not be able to use up its mana!

Is there no solution? No way! This is a dungeon, and there must be a way to target it in the dungeon!

Think again, what exactly is missing? First is Ada's diary, then the patchwork monster, then the key, and finally the boss's notes......
