Catherine couldn't help but feel anxious when she saw Yenifa staring at the interior of this laboratory with a ruthless look, and hurriedly looked at Yenifa wildly, signaling him not to act impulsively, no matter how precious and tempting the things here were, they had to have their lives to enjoy them!

But Yenifa was unwilling to retreat like this, and finally came to make a trip, and let himself discover such a place, which was simply a burst of luck! If he didn't take the sheep and get something back, he would really be unwilling. Pen ~ fun ~ pavilion www.biquge.info

But Yenifa is not a fool, a formal wizard's laboratory is definitely not something that a junior apprentice can forcibly break in and loot things, even if other official wizards enter, they may not be able to please him, let alone him?

Catherine looked anxiously at Yenifa for fear that he would rush into the laboratory as soon as his brain was hot, and then be beaten into a sieve by various defensive traps.

"Look, Catherine," Yenifa smiled with joy after taking a closer look, "Look at the magic steel alloy of this passage, this material seems to have been weathered, and there is not much durability left. ”

"So what?" said Catherine, shaking her head.

Yenifa didn't speak, but directly took out a test tube and sprinkled the transparent liquid in the test tube directly on the wall of the magic steel alloy.

"If my guess is correct, then there should be a chance...... No, there should be a chance!" Yenifa looked nervous with a rare hint of nervousness, his eyes fixed on the alloy wall spilled with the potion.

Under the erosion of the liquid medicine, the alloy wall began to slowly emit a little bubble, but the speed of the bubbles was very slow, and the bubbles were also very small, the corrosion resistance of the magic steel alloy was the strongest among metals of the same price, and the Yenifa configuration could only be regarded as a potion, not an alchemy potion, so it naturally could not corrode the wall.

But Yenifa didn't want to corrode the alloy wall with this potion, he just needed to do an experiment.

Yenifa pulled out a small miniature hourglass and began to count the number of bubbles as he kept his eyes fixed on the reactive locations.

After all the potions had been consumed, the alloy walls had only darkened a little, and they hadn't eroded off at all.

"What are you doing here, are you trying to corrode this wall with a few potions of yours?" Catherine thought Yenifa was doing useless work.

"I just wanted to do an experiment, did you know that there is an indirect way to determine the life of the magic steel alloy?" said with a confident smile on his face, "I just used the highly poisonous potion to erode the magic steel alloy, and the rate at which the two react with each other to produce bubbles is about 90 per second, the corrosion resistance of the magic steel alloy is about 30 degrees, and the corrosive strength of the highly poisonous potion is about 3 degrees, so I can bring these three known quantities into the calculation formula......"

Yenifa took out a piece of paper and a pen from the snakeskin pouch, and calculated them there, the quill fluttering in his hand, and the pen walked like a dragon and a snake, quite like the style of a paper in his previous life.

“...... Coupled with the radial load fatigue coefficient of the magic steel alloy and the error of five percent, it can be concluded that the magic steel alloy wall here only has a life span of seventy-five to eighty-five years before decaying. Yenifa quickly calculated the number and wrote down the numbers 75 and 85 on a piece of paper.

"The lifespan of the magic steel alloy made by ordinary methods is about five hundred to five hundred and eighty years, and there is only seventy or eighty years left here and the alloy wall, what does this mean?" Yenifa put away the mess in his hand and pointed at this laboratory with confidence, "This laboratory is a site almost five hundred years ago!"

Catherine watched Yenifa's actions a little blankly, and her heart was a little shocked.

At this moment, she had a new level of understanding of the phrase "knowledge is power".

"And the witchcraft spells laid down by most official wizards have a lifespan of only four or five hundred years at most, which means that!" Yenifa waved his hand, "The various witchcraft traps and defense techniques in this laboratory are likely to have failed!

"Do you know what that means? It means that we have a fair chance to loot the property here!

"Hey, but even so, a full-fledged wizard's lab is dangerous! The devil knows what that wizard got in the lab before, I guess those frost spirits escaped from this lab! There must be more powerful magical creatures, don't forget, this murderer may also be in this lab!" Catherine saw that Yenifa was about to be carried away by greed, and hurriedly poured a basin of cold water on him.

Yenifa was stunned for a moment, and the impulsive blood gradually subsided.

It's been determined that there's an even more powerful being behind the Frost Wraith, and this powerful creature is the culprit responsible for the time of Shining Silver, and at the same time, there's a lab here, making it hard not to connect the two.

Perhaps, whether it was the Frost Wraith, the Yin Spirit he first met, and the murderer, it was actually the owner of the laboratory who kept it in the laboratory?

If that's the case, then this laboratory is really not as safe as I imagined, although the traps and spells are almost ineffective, but there are unknown creatures in the laboratory, and there may not be only one, there may be many.

"But having said that, I won't give up on this laboratory, isn't it just a few magical creatures, no matter what, it is much less dangerous than the defense spells arranged by the official wizard, there is still a chance!" Yenifal pulled over Catherine and looked into her eyes, "Aren't you impressed at all? This is the official wizard's laboratory! Just a little bit of it will be enough for us to use it for a long time, and maybe we will benefit a lot!"

Catherine couldn't be tempted? As long as she got something left by a formal wizard, even a little scrap, it was a great asset for a junior apprentice! How could she not have thought about it?

Under Yenifa's strong persuasion, Catherine couldn't help but be a little shaken, thinking about it carefully, what Yenifa said was also right, the danger of several magical creatures was still within an acceptable range, and the wealth and danger were sought, not to mention that the risk did not seem to be particularly large!

"Yes, but there is one thing, if there is even the slightest danger beyond our ability, we must get out of here with me at once!" Catherine finally failed to resist Yenifa's persuasion, and agreed.

"Okay, then let's quickly start searching this laboratory, be careful, although theoretically the defense technique should be almost ineffective, but it cannot be ruled out that some techniques are still effective, and there are enemies watching in the shadows. Yenifa nodded, and said as he walked slowly toward the end of the passage.

The alloy passage was very long, and the two of them cautiously and slowly passed, and walked for more than ten minutes before finally walking out of this passage and coming to a stone gate.

This stone door was tall and vicissitudes, it was very old, and it even had fine and dense cracks, and the door was covered with moss and green thick vines, which wrapped the whole stone door.

"This is supposed to be a golem that was originally made in the shape of a stone gate, the first line of defense against intruders, and only those who are allowed to enter it may no longer be effective. Yenifa watched cautiously for a moment before slowly walking over and slowly approaching the stone gate.

The stone door remained motionless, like a dilapidated scrap door.

Yenifa walked all the way to the stone gate, but the stone gate did not react, neither to drive away him, the intruder, nor to react in any other way.

"Trouble, this stone gate golem guards the entrance to this place, although the golem is invalid to save us from his expulsion, but correspondingly, we can't enter. Yenifa frowned and looked distressed.

"Can it be broken directly by force? The golem has already decayed and failed anyway, and it is possible for us even as a beginner apprentice to destroy it. Catherine suggested.

Yenifa nodded, and shook his head again: "It is indeed possible to directly destroy this rotten golem by violent dismantling, but this may trigger a chain reaction, the golem is the first line of defense, and there must be a plan here to prepare for the destruction of the golem." ”

"If that preparatory plan is activated, then we may not be able to eat and walk around. ”

Catherine nodded, and then wondered, "Since this place has been blocked, how did the frost ghosts and yin spirits get out before? ”

Yenifa was stunned when Catherine heard this, and then stared at the stone door closely.

"Vines. Yenifa said suddenly.

"What?"

"These vines, these vines should be the reason why those frost spirits can enter and exit freely!" Yenifa stepped forward and pulled the vines, the vines did not move at all, and they were very strong.

With Yenifa pulling violently, the vines suddenly bounced up from the stone door and whipped towards Yenifa like a whip!

Yenifa was too close, and was caught off guard and was slapped in the chest, with a "snap" sound, Yenifa was directly pumped out by this vine, and fell ten meters away!

"Damn!" Yenifa felt a sharp pain in his chest, his skin was torn, and blood was pouring out quickly.

Fortunately, Yenifa has several protective sorcery on his body, which neutralizes a considerable part of the attack strength, but even so, it is still sucked open, and the two defensive sorcery of "Golden Stone Oath" and "Grip of Light" are directly dissipated into points of light, which is a phenomenon that can only occur when encountering attacks that exceed the limit of defense.

"I'm afraid the attack power of this vine is close to about 8 degrees, which is already the level of a mid-level apprentice!" Yenifa forced himself to get up from the ground, staring at the vine not far away with a worried face.
