The filthy stench of the underground sewer made Tang Yu despair.

He felt as if he couldn't get out.

Because there are more and more forks in the road ahead, he can only choose one randomly, originally he thought that if he kept going, he would definitely be able to walk to the Wuling River.

However, it backfired, and the more he walked the fork in the road, the more forks in the road meant the closer he was to the center of Wuling City, and he felt as if he was going in the wrong direction.

A city's underground waterways are huge, and there are great dangers that can come at any time.

Obviously, the remnants of the Sage Sect must also be searching for them in the underground waterways at this time, and once he encountered them, Tang Yu didn't think that his few simple apprentice-level magic could deal with them.

The point is that the stench here makes him unbearable and often feels suffocated......

"What should I do? If it doesn't come true, I won't find a way out?"

The picture that Bruce had left for himself that day in the temple of saints suddenly came to his mind.

A small water tank with two test tubes connected to each other, the third test tube is connected to the outermost part through a three-way glass tube, and there is an alcohol lamp underneath......

"That little water tank, is that the sewer it refers to......?

"The sewer should be a glass pipe that is connected. ”

"And what is the little tank?"

Tang Yu had an idea, and felt that he should follow the direction of the water, no matter what, if the water flows low, he will definitely find a way out.

He figured this out, and his heart was overjoyed, and he hurriedly looked for a fork in the direction of the current, but in his heart he was not convinced of the previous despair, and felt strength.

After walking for about half an hour, the water became more and more turbulent, and his heart became more excited, and he hurriedly quickened his pace.

"Oops......"

He only felt his foot in the air, and his body began to fall uncontrollably.

Before he could chant magically, his body fell into a foul-smelling deep pool, and he quickly slapped the water with his hand, still being poured a few mouthfuls of stinky water.

He panicked, but fortunately, the underground waterway was narrow, and he barely managed to hold on to a small piece of rock protruding from the side wall with one hand.

"Phew!" he spat out the water in his mouth, but suddenly a flash of inspiration flashed in his mind:

"Hey, isn't this the glass water tank?"

As soon as he thought of this, he looked around the sides, and sure enough, he saw two forks on the left and on the right, but there was no water in them.

Anxious and speculative, he cautiously moved to the fork in the road and walked forward slowly.

This fork in the road went all the way up, the slope was very steep, and Tang Yu used both hands and feet to barely climb up.

"If that strange picture really hints at the environment here, I should be able to find a fork in the road if I keep climbing up......"

"The fork in the road leads to the highest test tube, where it should be near the ground......

Trapped in the underground waterway for more than an hour, Tang Yu was already exhausted, but at this time he found a life-saving straw, but he still gave birth to a lot of strength.

Sure enough, when Tang Yu climbed to the top, he saw another steeper fork in the road.

Tang Yu gritted his teeth and continued to climb up the steep fork in the road.

After only a few steps, he stumbled and rolled down.

He climbed three times in a row, but all in vain.

There was a little despair in his heart, and at this moment, he faintly felt that there seemed to be a light in front of the fork in the road.

"I don't know if the light is an exit or if the damned saint is searching for him......"

Tang Yu rested for a moment, feeling that he had no other choice but to gamble.

He gritted his teeth and decided to continue climbing, and this time, he had made a lot of effort and had risen two or three meters high.

The light above is getting brighter and brighter, and the ** in Tang Yu's heart is getting stronger and stronger.

He felt like a moth, knowing that the bright place might be a fire, and he would burn to death if he threw it, but he still couldn't suppress his inner desire to survive.

He gritted his teeth and was ruthless, coupled with the strong support of survival **, he tried his best to move all the way up.

"Huh?"

When he climbed up with one hand, about to find a bulge to protrude, but touched the edge of the passage, he hurriedly used his strength, and his whole body was dragged up in the passage.

"Hoo ......"

He let out a long breath, feeling like he had finally walked through this difficult passage.

He was exhausted, but when he looked around, he couldn't help but stand up.

"Here......

It is like an extremely secluded attic, with light coming in on all sides, and it is about 34 square meters in size.

Two long tables, one on the left and one on the right, occupy most of the area here.

On the long table are all kinds of different experimental utensils, there are glass beakers, test tubes, mirrors similar to those used in physics experiments, trolley tracks, small metal balls, and many reagent bottles, crucibles, alcohol lamps, petri dishes, this is simply a laboratory.

The most striking thing is that on a table on the left, there are all kinds of strange materials, most of which Tang Yu does not recognize.

But through the magical aura emanating from these materials, he could easily tell that they were some magical materials.

Tang Yu couldn't care about being tired, and hurriedly leaned over, and in the empty space of the table, a page of white paper was nailed to it with a quill pen.

The ink on the white paper is dancing with dragons and phoenixes:

"Dear Don, I'm happy with the gift I left for you, don't believe the of the Wizard's Hut, this is our private lab......"

Densely packed, it was full of words, and between the lines was Bruce's tone.

In the letter, Bruce gave a detailed account of the operation of the various utensils in the laboratory, as well as the classification of some magical materials.

Finally, Bruce teased, "Don, you must remember that this was once the laboratory of many formal magicians, and you should be proud......

The corners of Tang Yu's mouth curved into an arc, and he couldn't help but think of Bruce's appearance in his mind, although he didn't have much contact with Bruce, but he really had a good impression of this Westerner.

"It's a pity that a magic book is missing......"

The environment inside the hut is very good, and on the table, Blue tears left a detailed laboratory operation guide.

Tang Yu found a bathroom according to the "Guide", took off the dirty clothes outside, took a comfortable bath, and then washed the coat and dried it with the magic pattern blowing in the bathroom.

"What is this?"

Tang Yu remembered that it vaguely seemed that Tao Fuzi had stuffed something for himself.

He hurriedly took something out of his black one-piece coat and looked at it, it was a book.

"The Encyclopedia of Magical Apprentices?"

"A magic book?"

Tang Yu was overjoyed, he couldn't wait to open the contents, and saw that the book introduced "Gewu", "Elements", "Biology", "Astrology", "Magic Patterns", etc., the general knowledge required by magic apprentices was recorded in the book.

"What is really missing, with this book, can't I continue my magic practice?"
