After summarizing the past few days, Su Che determined that for more than an hour in the noon period, the stewards and disciples of the best medicine field all practiced and did their homework after lunch, and basically did not come to the medicine field. So, at noon on this day, Su Che was well prepared and came to a cliff near the best medicine field.

According to the memories of the prisoner 'Han Youming', a topographic map left by his father shows that the general location is here.

The cliff here is extremely steep, and it belongs to an extreme position of the second-story medicine garden, and there is no connection with the bottom medicine garden. Looking down from here, it is a real cliff, shrouded in clouds and mist, and it is impossible to judge the specific height.

"Master, the strange-shaped boulder in front of you is the most accurate coordinate point, take the boulder as the starting point, cross the front twelve zhang in the southwest direction, and then climb down the rock for more than one hundred and sixty zhang, in order to find a hidden hole located on the cliff. Lao Hei sighed: "The distance of one hundred and sixty zhang is beyond my detection range, and I can't see the entrance of the cave for the time being, so I need the master to take the risk of climbing." ”

"It doesn't matter, the medicine collectors among ordinary people can climb the vertical rock wall, not to mention, I'm still an immortal cultivator. ”

Su Che followed Lao Hei's guidance, determined the final position with a strange-shaped boulder on the edge of the cliff as the coordinates, and began to climb vertically downward.

The natural cliff wall cannot be as smooth as a mirror, and you can always find protruding stones or stone crevices or something, which is really difficult for an immortal cultivator like Su Che, not to mention, there is also an old black perspective detection, which can remind Su Che to avoid those loose or rotten rocks.

Han Youming's father emphasized in his last words that in order to avoid being discovered, whenever you enter and exit the cave, you can't climb with the help of ropes, because the stewards and disciples here are all masters in the late stage of Qi training.

Back then, Han Youming's father was because he had harvested a spiritual weapon-level flying magic weapon, and on a whim, he flew around outside the cliff, but because of his strength, he was still a little reluctant to control the spiritual weapon, and accidentally hit the cliff and suddenly knocked out a big hole.

Su Che couldn't fly, so he could only climb a little bit like this, and it took a long time to drop a height of more than 160 zhang.

Lao Hei had already determined the location of the entrance of the Hidden Cave Mansion and reminded: "One zhang away from the lower left, Han Youming's father has laid some small mechanisms to cover the entrance of the cave, which are simple and practical, and they have been twenty years later, and these mechanisms are still effective. ”

The method of opening these small mechanisms is not difficult, and Su Che successfully drilled into the narrow hole more than one person high under the guidance of Lao Hei. This hole was knocked out by Han Youming's father, and for the sake of secrecy, he did not expand the hole again.

Entering the cave, Su Che activated the mechanism and closed the hole again. No matter how you enter or exit, this hole cannot be opened for a long time, and only by being so careful can you ensure that a secret will not be discovered by others for a long time......

The entrance of the cave was closed, and it was pitch black inside, which did not have any impact on Lao Hei's detection ability, but Su Che still took out an illuminating spar with his surname, and if he entered a trace of true qi, he could illuminate a range of several zhang.

The entrance of the cave is closed all the year round, and the air in the cave is fresh, which shows that the cave has a natural ventilation channel here. At this point, Su Che was not surprised, because the requirements of the high-grade spirit grass on the living environment were extremely harsh, and if the living conditions in the cave were not good enough, the spirit grass would not be able to survive.

At this moment, the position is a narrow and winding natural road, and the feet are also rugged, Su Che is holding the lighting spar and flying forward, the speed is not slow.

Lao Hei had already detected the road ahead, and if there was danger within a hundred zhang distance, he would definitely have time to alert Su Che, so Su Che could rest assured that he could boldly show the fastest speed.

"This road is really long enough!" Su Che silently calculated, he had already run a distance of more than three hundred zhang, and the front was still unfathomable, this hidden cave was indeed deep into the belly of the mountain.

Lao Hei said with a smile: "It's because it's hidden deep enough, Tianxuanzong has been inherited for tens of thousands of years, and only Han Youming's father has discovered here, and the 'Xuanji Venerables' of the past generations have no knowledge of this place." ”

"Definitely. Su Che also said, "Even if they are great cultivators in the Yuan Infant Stage, their divine sense cannot penetrate too deep into the rock formations. ”

galloped all the way, ran hundreds of feet deep, and finally heard Lao Hei let out an extremely exaggerated voice: "Wow! I'll go to it for a ......."

Su Che immediately guessed that this road was about to come to an end, and Lao Hei saw some kind of landscape in the belly of the mountain in advance, so he let out such an exclamation.

With great anticipation and excitement, Su Che accelerated under his feet, like a final sprint, wrapped in a stream of air, and staggered forward.

Wow!

After turning a few twists and turns in a row, the light suddenly brightened in front of him, and the illuminating spar in his hand was completely useless......

Su Che braked suddenly, stood at the end of the corridor and froze!

It is a large cave, with a radius of 100 zhang, and there are countless crystal pillars hanging on the top of the cave, the shortest of which is several feet long. These pillars are fluorescent and have different colors. Countless glimmers of light converge together, illuminating the entire cave in a colorful and bright light, like an incomparably wonderful illusory world.

Looking at the bottom of the cave, in the soil, in the cracks in the stones, and on the stone walls, all kinds of spiritual grasses growing everywhere, Su Che could identify some of them: Nine Yang Fruit, Red Flame Fruit, Pei Yuan Fruit, Blood Ginseng, Purple Snow Lotus, Fog Spirit Flower, Colorful Lingzhi, Seven Leaf Moon Orchid Branch......

There are many more varieties that cannot be named for a while.

"It's a pity, it's a pity!"

Su Che was still shining with golden light in his eyes, and he was extremely excited, but when he heard it, Lao Hei couldn't stop shaking his head in the immortal prison, shouting pity.

"What is a pity?" Su Che asked in his heart, taking a deep breath, trying to calm his agitated emotions.

"Master, haven't you noticed that the innate grade of these spirit grasses is mostly high-grade, and there are fewer medium-grade ones, but you can't see a single top-grade spirit grass. Lao Hei reminded in a low voice.

"Really?" Su Che was stunned, and muttered in his heart: "I was thinking just now, the spirit grasses I know are all high-grade and medium-grade, and those spirit grasses that I don't know are rare varieties that I have never seen...... Aren't they the best spirit grass?"

"No, it's not. Lao Hei pointed to the thick 'Spirit Sketch Illustrated Book' at his feet and said, "You have to cultivate diligently, and you haven't found time to read these books yet, but I have memorized them all." I recognize the spirit grass here, and there is indeed no one of the best. ”

"What's going on?" Su Che was puzzled in his heart: "Although Han Youming's father didn't describe these things in detail in his last words, however, I always thought that the entrance of the cave was near the best medicine field, and the spirit grass here should be ......"

Speaking of this, Su Che himself suddenly realized: "Oh, although the entrance of the cave is located below the best medicine field, but the tunnel in the cave is more than a thousand zhang winding, and the area above this cave is no longer the area of the best medicine field......

"Yes, master. Lao Hei analyzed: "Just now, I calculated the route when I came all the way, and I can basically conclude that this cave is located directly below the top-grade medicine field. Then, the reason for the formation of this secret medicine garden should be that the spiritual grass seeds of the top-grade medicine field were washed into the underground spring channel of Xuanji Peak by the water during the rainfall season, and then came here with the underground spring water, and over time, such a strange scene was created. The Tianxuan Sect has been established for tens of thousands of years, and such a long history can create countless miracles, and this natural medicine garden hidden underground is one of the miracles. ”

After listening to Lao Hei's explanation, Su Che was speechless for a long time, and he sighed deeply in his heart: "Yes, tens of thousands of years, how long, and what kind of miracle has the opportunity to be presented." However, the so-called miracle in the eyes of us little people is just a random stroke of God's creation. ”

Regarding what Lao Hei said, 'It's a pity that there is no top-grade spirit grass', Su Che didn't feel anything to regret. People must know that such a natural medicine garden is already a super treasure that they will laugh at in their dreams.

These spirit grasses have grown underground for I don't know how many years, and no one has picked them, it seems that Han Youming's father has indeed only consumed a small part, so the medicinal age of these spirit grasses is very long.

Su Che was curious in his heart, and asked in his heart: "Old Hei, the Tianxuan Sect has been established for tens of thousands of years, I don't know, is there a 10,000-year-old spirit grass here that is about to become refined?"

"No way, master. Lao Hei explained: "Although this cave is close to the underground spiritual veins, spiritual springs, air, light and other conditions of Xuanji Peak, after all, it is a closed place, and there are no conditions and opportunities to achieve the Ten Thousand Year Spirit Grass. Moreover, with so many spirit grasses gathered in one place, there was also a subtle competition between them, and any one spirit grass that was too strong would deprive the other spirit grasses of their right to live. Therefore, the spiritual grass here has a maximum lifespan of a thousand years, and when the life limit is reached, it will naturally wither. ”

"Yes. Su Che nodded in his heart: "Ten Thousand Year Spirit Grass, how easy it is to say, I don't know how much Heaven and Earth Essence is needed, what harsh growth conditions, what kind of chance to create, in order to create a Ten Thousand Year Treasure...... It's the same with us immortal cultivators, the immortal road is difficult, the competition is fierce, and the road to achievement is so slim!"

The treasure was in front of him, and Su Che was of course in a mood and full of emotion. However, the mental communication with Lao Hei was as fast as lightning, countless times faster than normal conversations, so there was not much time wasted.

Next, it's harvest time, so how do you collect the spirit grass? how much does it collect this time, and how do you keep it?
