After Lin Yu finished speaking, he nodded solemnly towards the black shadow.

Then, under the guidance of the black shadow, Lin Xuan began to cultivate, saying that he was cultivating, but in fact, he asked Lin Xuan to climb from the first floor to the top of the tower.

There are 99 floors in this tower, and you can climb up from the first floor. Even if Lin Xuan was in good health, after climbing it again, he was already tired and panting, and sat at the staircase of the ninety-ninth floor, shouting that he was too tired.

As for the Black Shadow's intention, he wanted Lin Xuan to start cultivating when his physical fitness reached the strongest state.

His exercises are not only powerful, but also extremely demanding on the body, and it is difficult for an ordinary body to withstand such a strong exercise. In addition, Lin Yu has never been in contact with these, except that the meridians of his legs are very strong, but the meridians of his upper body have been in a state of development, which can almost be said to be completely no different from ordinary people.

Cultivation requires not only talent but also a good body, the former in the eyes of the black shadow, Lin Xuan does not seem to have it, although the cultivation has not yet begun, but the black shadow has lost confidence in his talent.

As for the body, I still like it a little, after all, it is still small, and the whole body is still in the middle stage of development, as long as it is not fully developed, it is still very promising.

And this is the first criterion why the spiritual university selects people under the age of 20 to participate in the admissions.

For three days in a row, Lin Yu didn't do anything, just kept running the stairs in the tower, and he had long since ignored the shouts outside the tower, and let them toss outside. In the past three days, Lin Yu's body has been exercised with little effect. The next step is the quenching of the meridians.

The dark shadow led the exhausted Lin Yu to a huge Dan furnace-shaped room on the 88th floor.

"Boy, undress, go in"

The black shadow stood aside, and after saying to Lin Yu, he floated to the stone platform behind the pool.

Lin Yu glanced at the black shadow, so he had to take off all the clothes on his body, and the whole person walked in and lay down in the huge bath in the room.

As Lin Xuan lay in, the black shadow opened a reddish-brown valve from the side of the stone platform, and a blood-red liquid gushed out from the bottom of the pool, and the liquid emitted a rolling heat wave, wrapping Lin Xuan's whole person inside.

"It's hot, uncle is really hot, what the hell is this?"

As soon as the liquid touched Lin Xuan's body, the whole person immediately jumped up and ran towards the pool wall.

"Get in, this is the lava rift that I brought out from the undead realm with a lot of energy during my lifetime, which is very good for the tempering of the body and the tempering of the meridians."

"It's not going to be magma, are you?" are you going to train me or kill me?"

Lin Xuan glared and roared loudly at the black shadow

"Why did you kid react quickly" The black shadow looked at the slippery Lin Yu with a playful face, and couldn't help shaking his head

"Boy, go in, this is not magma, this is the fire spirit of magma, if it were magma, your kid would have died a long time ago"

Lin Yu saw that the black shadow looked serious, although he couldn't tell whether the black shadow had a face or not, but secretly guessed that under the black aura of the black shadow, it must be a fierce uncle with a face full of stubble.

"Okay"

After hearing the black shadow's explanation, Lin Yu carefully lay back in the bath.

The fiery red lava slurry was glowing with heat, and it slowly flowed from Lin Xuan's legs, back, and head.

The entire large pool was covered with magma, and Lin Yu's whole person was completely wrapped in magma. The black shadow closed the valve in his hand and floated in the air quietly waiting for Lin Xuan to absorb it.

Although the lava was hot, it was not as hot as the lava, and the temperature was not high, but the heat wave in it was tumbling and tumbling, filling the whole room with heat in an instant.

Lin Yu's body was neither burned nor scorched, but showed an alternative redness, reflecting the meridians in his entire body as if they could be faintly seen, and the fiery red spiritual thoughts, with Lin Yu's breathing, drilled into the open pores of his body, and kept wandering among the meridians, shuttling, shuttling, and swimming.

For a whole day and a night, the molten slurry in the pool gradually lost its light, and little by little stains were excreted from Lin Yu's body through the pores.

For a moment, a foul smell filled the room.

Fortunately, the black shadow was prepared, took out a small bottle of blue liquid from the drawer on the side, dripped it in the pool, and took out a small white flower with a strange fragrance, and threw it in.

The black stains poured towards the white flowers, and a piece of white petals was eroded into jet black, and the blue liquid flowed around Lin Yu's body.

In an instant, there was an indescribable comfort in Lin Yan's body, and the whole person felt extremely relaxed from the inside out.

It took another day for the entire pool of molten slurry to disappear completely. At this time, Lin Xuan walked out of it, feeling full of strength all over his body.

The whole person's spirit was surprisingly good, and the fiery red thoughts in his eyes surged, and he pressed straight out of the room.

"Boy, I didn't expect it, it was much faster than expected"

The black shadow nodded at Lin Xuan quite proudly, as if it was not Lin Xuan who was lying in it just now, but himself.

"Okay, hurry up and put on your clothes, and follow me to the Dan room on the thirty-sixth floor to find some pills, and then refine them."

The black shadow floated to the door, and after saying it to Lin Yu, he floated out.

Lin Yu behind him was very excited at this time, looking at the body extracted by magma, white and flawless, and the scars left by the injuries in the ruined city did not know when they would fall off.

The whole person is refreshed, he looks more confident, his consciousness is clearer, his mind is more open, and his heart is more solid.

The change in his body made Lin Yu ecstatic, and he pushed open the door and followed the black shadow out.

From the eighty-eighth floor to the twenty-fifth floor, Lin Yu ran down as soon as he puffed up, without feeling any breathing, and the whole person was still in good spirits. It seems that the workout has been fruitful these days.

Under the leadership of the black shadow, Lin Yu walked into one of the Dan rooms, which was filled with countless vials, each vial looked very valuable, if it was placed in the abandoned city, it was a good thing for people to grab their heads, but I didn't expect there to be so many here.

Lin Yu couldn't help but swallow his saliva, his eyes staring fiercely as if he had seen a treasure.

"Let's take a few bottles and eat them"

The black shadow said to Lin Yu casually, as if these pills were like jelly beans to him.

In fact, it's true, all the pills on this layer are pills, healing ones, increasing cultivation, breaking ranks, all kinds of them, and the number of them can't be counted.

This was scavenged from all over the world when he was alive, and now it is open to Lin Xuan for free, such a good opportunity is in front of him, and Lin Xuan will naturally not let it go.

Picked up a bottle, smelled it, a fragrance came to the nose, Lin Yu poured it into his mouth, smashed it a few times, and felt that the taste was not bad.

picked up another bottle and poured it into his mouth, eating more than a dozen bottles in a row, Lin Yu felt that he couldn't eat anymore, although the pill was small, it seemed to be very hungry.

The black shadow's face was a little gloomy, and this kid seemed to really treat his elixir as a snack. He couldn't bear to eat this way, but now there is no other way to be reborn. It's all cheap, kid.
