After Han Leng successfully drew a fireball rune, he drew more than a dozen spirit runes in a row while the iron was hot, and all of them were successful, he put these spirit runes into the Qiankun bag, ready to use them when he went out in the future.

Han Leng has completely mastered the drawing skills of low-level spirit runes, as for high-level spirit runes, he still needs to cultivate himself to reach the knot before he can draw them, and now he has drawn more than a dozen low-level spirit runes, and he feels that most of the mana in his body has been consumed, and it took a few spirit stones to recover some of his mana.

Spring goes to autumn, the sun and the moon are like shuttles, in the blink of an eye, two years have passed, Han Leng's age has also reached twenty years old, and his cultivation has also improved to the late stage of foundation building.

The Soul Forging Sutra that can strengthen the divine soul, he has already practiced to the third level, and his divine sense can be comparable to that of a monk in the middle stage of the Divine Spirit, and the casting of the inferior high-level spells is even more handy, almost reaching the point of instantaneous, and there is no need to recite the spell.

At noon on this day, Han Leng sat cross-legged on the bed, there was a faint aura halo around his body, which looked very mysterious, and his eyes were extremely deep, as if they contained stars.

The qi machine is introverted, and from the outside, it is not obvious that he is a monk with spiritual power, but he will feel that he is just a mortal with a strong body, and after reaching the late stage of foundation building, his control of spiritual power has reached the point of moving at will, and he can even hide his spiritual power fluctuations without using hidden qi techniques.

He slowly closed his eyes, and his whole body relaxed, like a stone sinking into the sea, and all the sounds around him fell silent, as if he was cut off.

In his mind, a dream attic floated in the mist, this was Xuan Lingzi's memory attic, which stored all the cultivation experiences and cheats he had obtained in this life.

Han Leng's Divine Consciousness projected a Divine Sense Phantom in his mind, which was the same as Han Leng's appearance, and was slowly walking towards the Memory Pavilion.

At the beginning, his divine soul strength was low, and he could only enter the second layer at most, and when he wanted to go up, he would encounter fog obstacles and was not allowed to enter, this time he practiced the soul forging sutra to the third layer, and the divine soul was also comparable to a monk in the middle stage of the Yudan, in his mind, this time he should be able to break through the obstacles of the third layer, so he was ready to give it a try.

He had read the cheats stored in the attic on the second floor before, and there was nothing unusual, but this time he didn't stop at the second floor at all, and walked straight towards the stairs leading to the third floor.

When he was just halfway up, that layer of mist was rushing to his face, and with strong resistance, he pushed Han Leng's body down, and a chaotic shattered light suddenly appeared on Han Leng's Divine Consciousness Illusory, and there were faint signs of shattering, this fog didn't know what it was, but it could knock the Divine Consciousness Illusory Shadow away.

However, Han Leng had already comprehended the mist before, although it was aimed at the divine sense, as long as the divine consciousness was strong enough, it could break through.

Han Leng's deity didn't move at all, and his eyes were still closed. It's just that some fine sweat broke out on his forehead, and a determined expression appeared on his face.

His Divine Consciousness Phantom forced his way upstairs against the erosion of the mist, and when he completely walked into the mist, the true horror of the fog was revealed, and the fog in all directions instantly approached, constantly consuming his Divine Sense Phantom, and after only two breaths, one of his arms disappeared completely.

This made Han Leng feel a little impatient, he began to panic, and hurriedly accelerated his pace and walked towards the third floor, his body disappeared little by little in the fog, and there were bursts of sharp pain in his head, and his body trembled slightly.

Just when his phantom was only half-stretched, he finally stepped one foot into the floor of the third floor, and as he ascended to the third floor, the already mutilated Divine Sense Phantom instantly regained its integrity.

He could see what the attic on the third floor looked like, the spacious attic containing nothing but two golden books floating in the air and a piece of paper full of words.

Two books and a piece of paper on the third layer are enough to prove precious, and on top of this third layer there is a fourth layer, and I don't know what else is placed in it.

Han Leng approached the golden book and saw that one was written with the Soul Forging Sutra and the other was written with the Divine Crossbow.

Han Leng is no stranger to the Soul Forging Sutra, even Ye Zhenren, the head of the Xuanling Sect, has heard of this secret book, which is said to be hidden in Xuan Lingzi's body, and now seeing the Soul Forging Sutra on the third floor confirms this rumor.

As for the other book of shooting the god crossbow, it is a long-lost secret magic technique, Zhou Tianji's research puppet technique is a branch of the mechanism technique, this shooting god crossbow is the strongest one of the organs, it is said that in ancient times, a hundred shooting crossbows can directly destroy the strong in the refining period, but later because it is too domineering, it was surrounded and suppressed by the powerful people of all parties, and it was actually the piece of armor that killed the sect that made this crossbow, and the production method of the shooting god crossbow was also lost.

As for why Xuan Lingzi has a book on making a god shooting crossbow, it is also related to what happened thousands of years ago, and it is not something that Han Leng can know, he only knows that the God shooting crossbow is a very dangerous item, and it is also a powerful killing weapon.

Out of curiosity about the Divine Archery Crossbow, Han Leng was preparing to build a Divine Archery Crossbow by himself, and he also wanted to see how powerful the Divine Archery Crossbow was that could make even the cultivators of the Refining Void Period fear thousands of years ago.

He gently patted the two books with his palm, and they automatically melted into Han Leng's sea of knowledge and became a part of his memory.

In the end, there was still a piece of paper left, this paper was still a parchment scroll, faintly yellowed, full of ancient characters, if it wasn't for the fusion of Xuan Lingzi's memory to understand the ancient characters, he really didn't know what was written on this parchment scroll.

At the top of the parchment scroll are five big characters, written "Five Elements Ning Dan Method", this is an extremely rare knot pill exercise, as long as you follow this exercise to knot Dan, you can increase the success rate of knot Dan by three percent!

Han Leng's eyes involuntarily widened a lot, the sound of his heart hitting his chest rumbled, and the lips of the deity even dried up a lot in an instant, and his heart was very shaken.

It's no wonder that Han Leng had such a big reaction after seeing the parchment roll, after he entered the late stage of foundation building, he understood more about the difficulty of cultivation, from the middle stage of foundation building to a small realm in the late stage, it took him two years, and after reaching the late stage of foundation building, he found that his dantian was a bottomless pit, no matter how much spiritual power he refined, in the end, he could only condense a little true yuan, and there was still a big gap from the true yuan required to form a pill.

All this is because he doesn't have a knot to cultivate, and he only crosses the river by feeling the stones by himself, if he keeps doing this, his cultivation progress will be very slow, because knot pill is not a one-time thing, and it takes a long time to find a suitable direction for his cultivation.

And the method that many people have figured out by themselves is not very perfect, like this kind of exercise that can increase the probability of Sancheng Dan, if it is lost to the outside world, it will inevitably cause a group of monks in the later stage of foundation building to rob it, Han Leng can get such an exercise, and I don't know if it is the blessing of several generations of cultivation.

Without saying a word, Han Leng fused this set of exercises into his sea of consciousness, and then his divine sense phantom slowly dissipated in the attic on the third floor.

The deity in the room opened his eyes, his eyes were full of joy, and he hurriedly went to check the conditions for the Five Elements Ning Dan Method.

This Five Elements Condensing Pill Method actually needs the elixir of five attributes as assistance, which are Golden Sunflower, Water Heart Grass, Mu Luolan, Fire Lingzhi and Tuyuan Fruit.

Just these five elixirs, it is difficult to get together, and the fire lingzhi is extremely scarce, and I don't know if there is such a thing in this world.

In addition to these five elixirs, after collecting, you also have to meditate and cultivate near the Earth, Fire and Yin Spring, and the five elixirs need to be catalyzed with the help of Yin and Yang Qi to have an effect, which is another big problem.

After seeing these harsh conditions, Han Leng finally knew why this exercise could increase the chance of attaining the pill so much, even if he didn't use this exercise, just swallowing these elixirs in his stomach would increase the success rate a lot, not to mention cultivating in the Earth Fire Yin Spring, which was the best choice for monks to retreat, but this Earth Fire Yin Spring was a rarer existence than the Spirit Spring.

Even in this entire human realm, there are only a handful of Earth Fire Yin Springs that can be found, and most of them are occupied by the senior masters, even if the masters are willing to rent out the cultivation place, it will cost a lot of spirit stones in exchange for use time.

Although Han Leng had the knot pill technique, he couldn't put it into action immediately, so he still had to slowly gather the elixir he needed and then make plans.

However, the materials used in the shooting crossbow are common, and it only takes a hundred years of ironwood to make, and there are still a lot of such things in the human world, and when he went to the Yipintang Chamber of Commerce, he saw a vendor selling ironwood on the first floor.

After he studied the production method of the crossbow of the gods, he set off to Yipintang and directly took all the ironwood stalls on the first floor.

These people who sell ironwood are also good at doing business, and they directly discounted Han Leng, and then happily closed the stall and went home, Han Leng put all the ironwood into the Qiankun bag, and went up to the second floor to find the Li Hua to ask about the elixir.

This Li Hua didn't work for Han Leng because of her fox tricks, but deliberately snubbed Han Leng, the other guests had finished asking, and she began to chat nonsense by herself, and the guests who came in were all confused by Li Hua, looking at Li Hua with squinted eyes, and began to talk endlessly.

Han Leng stood beside the two of them like this, a little embarrassed, but the male monk was even more energetic, as if he intended to show Han Leng in order to show his charm.

Later, Han Leng was really impatient to wait, and was about to go to someone else to ask, at which time Li Hua sent the monk away, and then came to receive Han Leng.

"What are you going to buy this time? We don't have any rune paper to sell here. Li Hua said casually.

Han Leng smiled slightly, and he didn't feel dissatisfied with this in his heart, if he changed to a short-tempered one, I'm afraid he would have gone away at this time, how could the reception staff of the Chamber of Commerce treat guests like this.

"I wanted to ask if you have a fire lingzhi for sale here?" Han Leng asked with a pleasant face.

Seeing that Han Leng was not angry because of her indifference, her service attitude also changed a lot, she thought for a while and said: "If you go back to your predecessors, this chamber of commerce has not purchased fire lingzhi, firstly, this item is scarce, and secondly, the price is uncertain, our chamber of commerce generally only sells priced goods, such as fire lingzhi, which is a precious elixir, is generally only sold in the auction house." Turn left from the Chamber of Commerce, about twenty miles away, there is an auction house, which is close to Heguang District, and is one of the best auction houses in our ancient region, and the seniors can go there to have a look. ”

After hearing this, Han Leng nodded, then left the Chamber of Commerce and walked towards the direction of the auction house, he also had some thousand-year-old medicinal herbs on him, maybe he could sell a lot of spirit stones, so that he would not have to worry about cultivation in the future.

Not long after Han Leng left, that Mi Tan appeared at the door of the Chamber of Commerce, and after he walked into the Chamber of Commerce and talked to Li Hua, he walked out, and then he didn't know where he went.
