Han Li instructed the puppet soldiers to collect spirit herbs, then, without moving, he cast a spell with his fingers, and the cyan sword formation immediately flew towards another medicinal field not far away, buzzing as it operated.

Countless cyan sword qi rained down, enveloping the restrictions of the medicinal field, quickly breaking them.

Immediately, some of the puppet soldiers swarmed over, collecting all the spirit herbs here.

Around those medicinal fields where the restrictions had been broken, light flickered, and the restrictions slowly condensed again, like the starry light curtain outside the medicinal garden, capable of regenerating themselves.

Seeing this scene, Han Li's face revealed a look of admiration.

How many tens of thousands of years had the Underworld Cold Palace existed? That the restrictions here were still operating normally was already amazing, and they could even regenerate themselves. The person who set up these restrictions must have had terrifying array skills.

His heart grew more and more curious about this mysterious Underworld Cold Immortal Sovereign, just what kind of person was the owner of this vast palace?

With treasures before them, the three naturally went all out, quickly scavenging the medicinal fields on the periphery of the medicinal garden.

However, while Han Li used the sword formation to break the restrictions, he also used the puppet soldiers to collect the spirit herbs, resulting in extremely high efficiency, far surpassing Old Ancestor Cold Flame and Lu Yuqing, so most of the spirit herbs fell into his hands.

During this time, he also conveniently helped Lu Yuqing, breaking the restrictions on several medicinal fields for her, making Old Ancestor Cold Flame very envious, but he could only force a bitter smile.

Afterward, the three came to the depths of the medicinal garden, where the area of the medicinal fields was much larger than outside, and the restrictions were bright and dazzling, making it basically impossible to see the situation of the spirit herbs inside from the outside.

Han Li simply scanned with his eyes, confirmed that there was nothing unusual nearby, and immediately activated the sword formation, enveloping a dazzling red restriction light shield, and fiercely cutting and killing it.

Old Ancestor Cold Flame and Lu Yuqing also immediately each chose a medicinal field restriction and cast spells to break it.

As a result, this time, when the countless sword qi released by Han Li's Azure Bamboo Bee Cloud Swords struck the red light shield, although the light shield trembled constantly, it showed no sign of breaking for a while.

Han Li frowned, and changed the sword incantation in his hand.

The cyan sword formation suddenly shrank, converging towards the center, and after spinning around, it suddenly transformed into a huge cyan sword lotus.

He chanted incantations in his mouth, and the lotus petals of the sword lotus slowly bloomed, and on each lotus petal, there appeared dazzling golden arcs of electricity, crackling and hissing, and fiercely covering the red light shield.

Each lotus petal firmly clamped the red light shield, then rotated and tore.

The red light shield twisted violently, and after holding on for a while, it finally shattered with a loud bang, turning into a sky full of red light streams.

Han Li was delighted in his heart, and hurriedly looked inside, but the smile on his face suddenly froze.

On the medicinal field inside the light shield, there grew a yellowish-brown spirit tree. The tree trunk looked very rough, with deep, dry cracks appearing on it, but it gave people a vibrant feeling, obviously not an ordinary tree.

However, this spirit tree had been cut off from the middle, leaving only a section of the trunk here. The cut was still very fresh, and dots of yellow sap seeped out.

Han Li walked to the side of the tree trunk, a look of contemplation on his face.

Old Ancestor Cold Flame and Lu Yuqing were about to break the restrictions on other medicinal fields, but seeing this scene, they stopped and walked over.

"It seems that someone came here earlier. Looking at this cut, it was obviously not long ago, no more than a day," Old Ancestor Cold Flame judged, looking at the cut.

Han Li nodded and glanced at the starry restrictions above his head.

No wonder this starry restriction was so easily broken. It turned out that someone had broken it once beforehand.

Although this restriction could automatically recover, the time was too short, and it only recovered half of its power, so they were able to break it easily.

"Who is it? Could it be that Xiong Shan?" Lu Yuqing muttered.

"No, although Xiong Shan arrived at this Underworld Cold Palace a little earlier than us, there is clearly not enough time for him to come here and break the restrictions here," Han Li shook his head.

"Then who could it be?" Lu Yuqing couldn't help but ask.

"I don't know, but that person didn't touch the spirit herbs and medicines in front, I don't know if they didn't like them, or if they were in a hurry. It seems that there are no signs of fighting here, mostly the former. It should be some Golden Immortal senior," Han Li shook his head and said contemplatively.

There were many Golden Immortals who entered the Underworld Cold Immortal Mansion, and he couldn't determine exactly which one it was.

Hearing this, Old Ancestor Cold Flame and Lu Yuqing exchanged glances, talked for a couple of sentences, and then dispersed, continuing to break the medicinal field restrictions they had taken a liking to.

Han Li looked at the half of the tree trunk in front of him, lightly dipped a little yellow sap with his finger, smelled it in front of his nose, and his spirit immediately shook, and the divine sense in his mind felt at peace.

His eyes brightened, and he waved a cyan light, shrouding the tree trunk, carefully digging it out together with its roots and the nearby spirit soil, and put it away.

Although he didn't know what this yellow spirit tree was, that it could be favored by a Golden Immortal meant that it was definitely a precious spirit tree.

Although this tree had been cut down, Han Li had the Palm Bottle in hand, and there was still hope to revive it.

After doing all this, his figure flickered, and he came to another medicinal field, casting a spell.

The sword lotus in the air roared down, enveloping a bright blue restriction on this medicinal field.

Thick lotus petals cut the light shield, making a rumbling noise.

A dozen breaths later, the blue light shield also shattered with a bang, revealing the medicinal field below.

Han Li looked inside and his face sank.

The spirit herbs in this medicinal field had also been picked, and this time they had been picked very thoroughly, even the roots had been dug up.

He snorted, his figure flickered, and he flew to another medicinal field, casting a spell in his hand.

The sword lotus flew over, covering the cyan restriction on this medicinal field.

A quarter of an hour later.

With a "bang", an orange-yellow restriction shattered, revealing the medicinal field below.

Han Li looked into the medicinal field, his face slightly sullen.

The spirit objects in this medicinal field had also been dug up, leaving a large hole several feet deep in the spiritual field.

He shook his head and looked away.

At this moment, the restrictions on these spiritual fields in the depths of the medicinal garden had almost all been broken by the three.

Of course, the vast majority of them were broken by him.

The spirit medicines here had all been taken away by that outsider, and the three had gained nothing.

Some of the spirit objects left behind roots and stems. Old Ancestor Cold Flame and Lu Yuqing were not interested in these roots and stems, but Han Li did not let any of them go, and collected them all.

At this moment, Old Ancestor Cold Flame and Lu Yuqing were still breaking a spiritual field restriction each.

Han Li glanced at the two of them, then looked away, and looked towards the deepest part of the medicinal garden, where there was a medicinal field, the area of which was a hundred zhang large, much larger than other medicinal fields.

The entire medicinal field was shrouded in a thick purple light curtain, and wisps of purple electric arcs flowed on the light curtain, emitting a powerful aura, looking indestructible, like a purple beast lying on the ground.

This medicinal field was obviously different from the others, so the three of them didn't touch it and left it for last.

Han Li looked at the purple restriction, a strange color flashed in his eyes, and he was about to cast a spell to activate the sword lotus.

At this moment, a "boom" of cracking sound came from not far away, but it was Lu Yuqing who had broken a restriction, revealing the medicinal field below.

The restrictions here were even more powerful than before. This woman's face was a little pale, obviously she had consumed a lot of energy.

Lu Yuqing flipped her hand and took out a pill and swallowed it. Her beautiful eyes looked inside, and she couldn't help but show a look of disappointment on her face.

The things in this spiritual field had also been taken away, and they had been dug out even with their roots. Two big holes were left on the ground.

However, that person seemed to have dug in a hurry, and there were still a few shining white roots left here.

Lu Yuqing pouted and was about to turn around and walk away.

"These seem to be the bamboo roots of spiritual bamboo. Spiritual bamboo is different from other spirit herbs. Even if it's just bamboo roots, if properly cultivated, they can also take root and sprout, and grow new spiritual bamboo, which is quite valuable. It's a pity that Miss Lu abandoned them like this." Han Li didn't know when he had walked over and said.

"Does Brother Han recognize this spiritual bamboo?" Lu Yuqing asked with a happy face.

"I don't recognize it either, but these silver roots look extremely extraordinary. The spiritual bamboo that grows out must also be a immortal-grade, otherwise it wouldn't have been planted here by the owner of this medicinal garden. If you can find a knowledgeable buyer, these bamboo roots can also sell for a good price." Han Li shook his head and said.

Hearing this, Lu Yuqing nodded repeatedly, waved a cyan light, and carefully dug out the silver roots next to the two big holes, putting them into two jade boxes.

She flipped her hand and put away one jade box, and handed the other to Han Li, saying, "Thank you for your guidance, Brother Han, otherwise I might have missed this opportunity."

Han Li didn't feign politeness and directly accepted the jade box.

He was indeed very interested in these silver spiritual bamboo roots.

A rumbling sound came from another direction. Old Ancestor Cold Flame was currently activating a set of flying knife spiritual treasures, a total of twelve, which looked like spiritual treasures of extremely high quality, and transformed into blades of light, madly attacking a light blue restriction.

However, starlight flickered on the surface of this restriction, it was a starry restriction, and it was extremely tough.

He had already attacked for a while, but although water-like ripples appeared on the surface of this starry restriction, it remained motionless.

Old Ancestor Cold Flame looked a little anxious, and glanced at Han Li not far away.

A hint of contemplation appeared on his face, and he immediately stopped and flew over.

Han Li was checking the silver roots in the jade box, and when he saw Old Ancestor Cold Flame coming, he put the jade box away.

"Fellow Daoist Han, that restriction is quite difficult to deal with, can you help break it?" Old Ancestor Cold Flame cupped his hands and said.

"It's a small matter, Fellow Daoist Cold Flame doesn't need to be so polite. Miss Lu, let's go take a look together." Han Li smiled faintly and said.

"Thank you, Fellow Daoist Han." Old Ancestor Cold Flame said with a happy face.

Not long after, the three of them came to the starry restriction that Old Ancestor Cold Flame had mentioned.

Han Li's eyes flickered, and he sized it up.
