Dragon-killing vine. Nowadays, all cultivators only know that this vine is used to refine the Dragon-Trapping Rope. Although it is extremely powerful, it is not even close to its real purpose.

Dragon-slaying vines that are over ten thousand years old can be planted in the body using the secret transplantation technique. The host's blood and spiritual energy provide nourishment, and the strange fire can temper and strengthen the vines. When the body and the dragon-slaying vine are perfectly integrated, the vines can be activated to entangle any location within a thousand feet. The vines have barbs, which are highly toxic and have paralyzing effects. The most terrifying thing is that once entangled, each barb will slowly absorb the blood and spiritual energy of the prey to strengthen itself. This is the true purpose of the dragon-slaying vine.

The toughness and strength of the Dragon-Slaying Vine itself is rare in the world. As long as it is tempered with strange fire, its toughness will become stronger and stronger. Once it is entangled, it is impossible to break free and can only slowly become its nutrients. As its host, it is also a beneficiary. Although the things in it are extremely precious, in Ling Tian's eyes, nothing can compare to the Dragon-Slaying Vine.

"The Dragon-Slaying Vine has ten and almost eleven rings, which means it's nearly eleven thousand years old. There's still some energy left inside that hasn't been completely lost, so it should be no problem to keep it alive. First, grow it in the space and increase its age. By then, the vine's attack range will be wider. The Dragon-Slaying Vine can really kill dragons, hahahaha!

Ling Tian was very happy. This time the harvest was far beyond his expectations. Just this one Dragon-Slaying Vine had made him a huge profit, even the Xuantian Medicine Cauldron could not compare to it.

While Ling Tian was still immersed in the huge surprise, Su Qingyan walked over, opened a secret compartment, took out a fiery red pill, and swallowed it on the spot.

"Senior Ling, I need to practice for a while, please help me protect the law."

"good."

Ling Tian walked over to the entrance and sat cross-legged. He set up a magic circle and released hallucinogenic butterflies. Looking at the butterflies, Ling Tian was extremely satisfied. With the ten times flow rate in space plus the effect of the Soul-Feeding Pill, he was almost reaching the peak of level four and not far from level five.

Ignoring the hallucinogenic butterfly, Ling Tian turned his eyes to Su Qingyan who was cultivating. Her aura surged, shocking her. At the same time, he was curious about what kind of elixir it was, as its effect was too overbearing.

"He broke through to the middle stage of Jindan so quickly, and his realm is extremely stable. He doesn't need to spend more time to consolidate it. This pill is really amazing."

It continued until the peak of the late Jindan stage, when Su Qingyan stopped and looked at Ling Tian with a grateful smile.

"Congratulations, Fellow Daoist Su, your realm has improved very quickly."

"No, I just got some luck from my ancestors. This Emperor Thunder Pill is only effective for those below the Fusion Stage. It can only be taken once in a lifetime, and the improvement depends on the user's talent. According to ancient records, the most powerful person was Emperor Rencheng. He took it while he was in the Qi Refining Stage and directly reached the late Spirit Transformation Stage. My talent is average, and I only improved three small realms. What a pity, haha."

It can be seen that Su Qingyan was still a little disappointed, but she was broad-minded and soon thought it through. It was already very good to be able to reach the peak of the late Jindan stage. After settling down for a while, she would be able to achieve great perfection.

"It's just that this heaven-defying elixir can no longer be refined. One of the main ingredients has become extinct in the world. It's really a pity."

"Oh, that's not the case. What kind of elixir has become extinct?"

"Leaves of the Heavenly Thunder Bamboo, one of the three sacred trees, are over a hundred thousand years old. There hasn't been a single scrap of news about them in tens of thousands of years, haha."

Su Qingyan shook her head and sighed, then turned around to open another secret compartment. Just as she turned around, Ling Tian was overjoyed. Had a Heavenly Thunder Bamboo been planted in his space recently? Although it was only a few hundred years old, wouldn't a hundred thousand years be enough time?

"Excuse me, does Fellow Daoist Su have the recipe for this pill?"

Su Qingyan was a little surprised. She turned around and looked at Ling Tian, ​​as if trying to see through his thoughts. After a moment, she asked, "Brother Ling, do you have Heavenly Thunder Bamboo?"

"Indeed, it's only a few hundred years old. Perhaps one day in the future there's a chance it could reach a hundred thousand years. If not, I'll leave it to future generations. After all, there's something to hope for, haha!"

Ling Tian did not lie. Although it was one of the three sacred trees, it was too old to be of great use.

Su Qingyan didn't expect that Ling Tian would have such a sacred tree, but she was not excited at all. It had only been a few hundred years, but in order to refine the Emperor Thunder Pill, one needed 100,000-year-old Heavenly Thunder Bamboo leaves. 100,000 years! Even if one transcended the tribulation and ascended to become an immortal, one would not be able to live to that age.

But as he said, perhaps there is some hope left for future generations.

"Since Brother Ling has such a sacred tree as the Heavenly Thunder Bamboo, I will help him."

Anyway, the recipe is useless to her, so it is better to give it to Ling Tian to establish a good relationship with him. Maybe the Wheel of Destiny will be useful one day.

After giving the pill recipe to Ling Tian, ​​Su Qingyan took out the item from the second secret compartment. It was a jade pendant carved with the image of a monster. As for what it was, Ling Tian had never seen it before, but seeing the joy in her eyes, he thought it must be very precious.

"Brother Ling, let's keep going."

In this way, Su Qingyan took Ling Tian through the secret passage to find more than ten caves, and reaped a huge reward. In the last cave where spiritual medicines were grown, they also obtained purple vitex and Tongyou blood spirit ginseng.

After coming out of this cave, there was another secret passage full of traps. They soon returned to the original entrance. It turned out that they had walked in a big circle.

"Brother Ling, you can choose any of the twenty-four entrances here and enter. There will be some obstacles inside, but it shouldn't be difficult with your ability. However, be careful on the ninth floor, as it is filled with ancient poison arrays. You must be extra careful. Once you pass this floor, you can reach the top, where we will meet."

After saying that, Su Qingyan walked into one of the entrances, and a burst of light disappeared.

Ling Tian smiled. He was least afraid of poison, so without giving it much thought, he simply chose a nearby entrance and entered. A flash of light revealed him in a vast square, packed with tens of thousands of people. In the center of the square stood a tall tower. Seeing so many people coming in and out, Ling Tian was puzzled.

I walked over and observed quietly. It took me a while to figure out the rules here. It turned out that I had to break through the tower. If I broke through, I would get corresponding rewards. And only if I broke through the tower could I get the key to enter the next level.

"Fuck, just a little bit, I will definitely pass next time."

At this time, a figure in the tower was pushed out. He was furious because he couldn't pass. Ling Tian was attracted by it and turned around to see another cultivator quickly taking the position.

Although the tower only has eight entrances, the challenge is very fast, only about twenty breaths.

Ling Tian saw the right moment, and when a door in the tower suddenly flashed, he rushed over first. His speed was so fast that no one present could react.
