The basement of the Martial Pavilion was not as dim as Qin Yin expected, and there was an ever-bright lamp hanging on the wall every ten steps, illuminating the entire basement transparently.

Qin Yin went down the stairs and swept his eyes around, only to find that the walls of this huge underground cave were mottled and there were some inexplicable scratches.

There was not a hint of rotten musty smell in the air, and as soon as you closed your eyes, a heavy smell of history overwhelmed you.

Qin Yin took two deep breaths, calmed down the fluctuating emotions in his heart, and came to the secret room of the Martial Pavilion where the secret books and exercises were collected.

This secret room should not be described as a "room", but more like a huge underground palace, with a huge door plaque erected in each of the four directions.

"Heaven", "Earth", "Xuan" and "Yellow" are engraved on these four gate plaques, and under each gate plaque, there is a guard who is wearing heavy armor and looks like a human but does not have a trace of human breath.

Qin Yin held his breath at this time, the internal breath in his body ran all over his body, and a faint layer of ice mist rose on the surface of his body, looking at these four guards who were silent at this time with extreme vigilance, Qin Yin even had an illusion, as if as long as he moved slightly, he would incur a thunderous blow from these four guards, and although these four guards did not have the slightest breath of life, the feeling given to Qin Yin did not seem to be weaker than that of Prince Bian who he faced when he was in Zhongwutang.

"Martial Pavilion guards, let Qin Yin take two exercises, one for the middle grade of the prefecture level and one for the upper grade of the Xuan level. ”

At this moment, Prince Bian's voice came from the White Tiger Hall above the secret room, and then the breath that was originally overwhelming Qin Yin and not daring to move disappeared instantly, and then, the guard in charge of guarding the ground-level exercises stepped back suddenly, and the red light flashed in his eyes behind the mask, and then, I don't know what material it was made of, but the door that was as thick as a mountain suddenly opened, revealing rows of bookshelves carved from snow-white jade.

"Huh?"

A trace of doubt flashed in Qin Yin's eyes, and after a careful observation, he didn't feel a trace of killing intent anymore, but the guard of the prefecture-level martial arts was standing sideways at this time, making way for a space that could be passed through.

It's just that the strength of the four guards before really made Qin Yin jealous, so he was quite hesitant at this time.

"You hurry up yourself, it's only three hours, and the cheats can't be taken out of the Martial Pavilion. ”

Just when Qin Yin hesitated, Prince Bian on the White Tiger Hall spoke again, which also strengthened Qin Yin's determination, and as soon as he gritted his teeth, he displayed the Ice Battle Armor, and after protecting the surface of his body, he cautiously walked towards the ground room.

The space of the ground room is very open, there are more than 100 rows of bookshelves inside, but most of the bookshelves are empty, after Qin Yin walked into this empty room, he quickly scanned it, and finally looked at the row of bookshelves inside, unlike other empty bookshelves, these more than ten rows of bookshelves were full of books, which made Qin Yin involuntarily gasp.

Qin Yin already had a clear understanding of how precious the ground-level exercises were at this time, but such a precious martial arts were lined up with a dozen bookshelves in the Great Xia royal collection, totaling at least more than sixty of them, even if most of them were ground-level low-grade martial arts, such a huge number was still enough to shock everyone's hearts.

At this moment, Qin Yin deeply realized what Lord Wen had said before, that the dynasty was enough to merge into the sect realm holy land, and compared to this row of prefecture-level exercises, Qin Yin was finally convinced of this in his heart.

Qin Yin's eyes swept over all the bookshelves with books, and found that these cheats belonged to six categories according to fire, water, earth, wood, metal, and miscellaneous, among which the three major genera of fire, earth, and wood had the most exercise cheats, followed by water, gold, and miscellaneous.

The Bing surname is a different species in the water surname, so Qin Yin did not pay attention to the exercises of other surnames, and focused all his attention on the water exercises, after all, it is a big task to memorize the three exercises in three hours.

Coming to the bookshelf where the Han surname exercises were placed, Qin Yin took a closer look and found that these exercises had been placed in different positions according to the upper, middle and lower levels, and there were corresponding introductions on the horizontal ridge of the bookshelf.

"Weak water trick, surnamed Han Ning is heavy, with the "Three Thousand Weak Water" cast, it can increase the true qi by two times, and the prefecture-level is of high quality. ”

"Three thousand weak water, swordsmanship. Legend has it that there is a water name weak water under the netherworld, goose feathers do not float, a drop of ten thousand catties, this swordsmanship takes the name of weak water, once it is performed, it is like three thousand weak water, thick and heavy like a mountain, endless, drag the opponent into the realm of defeat, the ground level is of high grade. ”

"Canglong Water Resisting Technique...... Prefecture-level high-grade. ”

Qin Yin swept his eyes, pressed the impulse in his heart, and finally landed his gaze on the part of the ground-level mid-grade exercises.

Previously, Qin Yin had already obtained a "Heavenly Frost Fist" equivalent to a ground-level low-grade "Heavenly Frost Fist" from the Eighth Prince, and a ground-level middle-grade "Dragon Elephant Wheel Turning Fist" from the Lord Wen, plus the Xuan-level top-grade "Canglang Three Strikes" hanging in the dragon arena, this is already a three-door attack method, but the exercises for cultivating true qi and true qi are relatively lacking, so this time from the Wuge to get the ground-level middle-grade exercises, Qin Yin is ready to choose a mental method for cultivating true qi and internal strength, and a Xuan-level high-grade exercise to choose an arsenal move.

"Ground-level mid-grade exercises, immeasurable sea skills, Xuan Yin Soul Strength, Ice Spirit Frost Technique, Heavenly Dome Tyrant Cold Technique......"

Qin Yin's gaze swept over the list of these prefecture-level mid-grade exercises, and finally fixed on the "Ice Spirit Frost Technique".

Ice Spirit Frost Technique, the origin is unknown, the power is terrifying, and now the first four layers remain, and the practitioner is cautious.

There are very few introductions to this Ice Spirit Frost Technique, and it is very cold compared to the introduction of at least a hundred words for each of the other exercises, but Qin Yin has keenly discovered the extraordinaryness of this exercise, the word "Powerful Horror", although there are words such as powerful and amazing power in the other more than ten prefecture-level middle-grade exercises, none of them use the word "horror", that is to say, among these more than ten exercises, the effect of "Ice Spirit Frost Technique" is the strongest and most amazing. As for the fact that this exercise only has the first four layers, which is not complete, Qin Yin doesn't care, because with the powerful Taixuan Root Seal, which is regarded as a super hole card for cheating, Qin Yin has a strong belief that as long as the Ice Spirit Frost Technique and the Taixuan Root Seal are cultivated together, even if it is extremely time-consuming, one day he will be able to complete this powerful skill that ranks among the middle grades of the prefecture level only by virtue of the first four layers.
