Bailu Lake is a volcanic lake with very deep water.

After Gu Zheng and Lian Yuxin entered the water, they kept diving downwards.

Although Lian Yuxin is an immortal cultivator in the late stage of returning to the void, she has not refined the 'true water of life', so diving into the lake is not as easy for him as Gu Zheng.

Gu Zheng looks like she is descending the stairs, but she has a shield formed by a layer of immortal power on her body, which controls her rising and falling in the water.

The lake water is very clear, there are some fish, and some aquatic plants, and the food grade of these things can occasionally be seen as ordinary grade.

Gu Zheng and Lian Yuxin quickly dived to the bottom of the lake, and then Gu Zheng put his immortal power deep into the mud and began to break the immortal formation below.

This fairy formation is a bit difficult, but when the weapon spirit discovered it, he also took a look at how to break it, in order to facilitate the ancient fight in the future.

As for what kind of restrictions there are after this fairy formation, Qi Ling did not go any further to explore. After all, she only had two minutes to conduct in-depth exploration. She also wanted to see if she could do more in the limited time.

Gu Zheng found some treasures or something.

In addition to discovering the treasure of Bailu Lake, Qi Ling also discovered some ordinary-level ingredients in two minutes, as well as an island on the sea protected by an immortal formation.

Therefore, after Gu Zheng has explored the treasures of Bailu Lake, he will go to that overseas island to see what he will find there.

The fairy array at the entrance to the treasure was cracked by Gu Zheng, and bright light penetrated the thick mud and appeared in the water, forming a pattern of light array.

The mud at the bottom of the water seemed to be squeezed out by invisible forces, as if it was pushed by someone, leaving the range of the light array.

About three minutes later, the mud on the Immortal Formation was cleared away, revealing the hard magma rock underneath.

"Rumble..."

A gap opened in the magma rock, and the lake water was separated. Gu Zheng and Lian Yuxin followed the gap, and the gap closed again, and the separated lake water became its original appearance.

The crack that Gu Zheng and Lian Yuxin entered was very deep. As they kept walking along the crack, the temperature became higher and higher, and the temperature of the magma became richer and richer.

After a while, Gu Zheng and Lian Yuxin arrived in front of a stone door.

There is an immortal array on the stone gate. I have never seen this immortal array before. After trying it for a while, I couldn't open it, so I asked Lian Yuxin to try her array magic weapon.

Lian Yuxin took out the bead-like formation magic weapon. With a thought, she activated the magical power of the fairy weapon. Suddenly there was a slight light flickering on the bead, along with the light of the fairy formation on the door.

It flashed at the same frequency.

About ten minutes later, Lian Yuxin already knew how to crack the fairy formation. She input her fairy power into the fairy formation on the door, and soon opened the fairy formation.

"Rumble..."

The stone door opened, and a stream of dusty heat suddenly swept over.

Gu Zheng's poison-proof clothing automatically opens the shield to resist the fire poison in the heat. Lian Yuxin's body already has a fairy power shield on her body, so the fire poison from the lava will not cause any harm to her.

The world behind the door is fiery red, like a lava lake. There is a stone passage in it, leading to the stone wall at the end of the magma lake. Under the stone wall is a platform, and a large box is placed on the platform.

"It's such a big box, I don't know how many treasures are put here!" Lian Yuxin exclaimed.

"Yeah?"

Gu Zheng glanced sideways, looking at Lian Yuxin with a half-smile.

"Master, why are you looking at me like that?" Lian Yuxin smiled awkwardly.

"I was wondering if you were going to wait for me to move forward, then sneak attack me and kick me into the lava?" Gu Zheng smiled, as if he saw something very interesting.

"How could that be? Master, stop joking!"

Having said that, Lian Yuxin suddenly launched an attack on Gu Zheng.

Gu Zheng just smiled, and when Lian Yuxin was about to hit his face with a palm, he closed and opened his eyes, and everything in front of him was different.

Lian Yuxin stood beside Gu Zheng properly, with her eyes closed. There was indeed a box on the platform at the end of the magma lake, but it was not as big as the one he saw just now.

In fact, from the moment Gu Zheng and Lian Yuxin stepped through the door, they had already fallen into an illusion.

There are many ways to see through illusions, the most direct of which is that your cultivation level is high enough and your mental power is strong enough, so that you can feel the difference as soon as the illusion appears.

The spiritual power of a cultivator is his spiritual thoughts, and Gu Zheng's spiritual thoughts are undoubtedly powerful. For him, the illusion he experienced this time was not as powerful as the illusion of the Millennium Tridacna on Ziyan Island.

Since he knew it was an illusion, Gu Zheng was naturally not afraid of Lian Yuxin's attacks, and the illusion was broken as soon as he closed and opened his eyes.

It took about half a minute for Gu Zheng to break the illusion, and even Yu Xin also broke the illusion.

"There is actually an illusion!"

Lian Yuxin opened his eyes and smiled at Gu Zheng.

Lian Yuxin's spiritual consciousness was not as good as Gu Zheng's, so she escaped from the illusion relatively late and was not able to see through it immediately. However, Lian Yuxin was an immortal cultivator in the late stage of returning to the void after all, and her spiritual consciousness was already strong enough to a certain extent.

The stronger the spiritual will, the easier it is to detect broken formations in the illusion.

"Let's go and see what's in the box."

Gu Zheng smiled slightly and walked through the magma lake on the stone passage.

The seal on the box was opened by Gu Zheng, but the contents inside were not as much as expected.

There are some low-grade weapon refining resources, a bottle of unknown elixir, a jade slip and three resources that can be used as food ingredients.

"Well, these are the only things."

Lian Yuxin sighed, looking very disappointed.

Gu Zheng was also disappointed. After all, the grades of the three ingredients were only ordinary.

"Damn it, didn't you take away the legendary treasures of the two immortals of Yingzhou?" Lian Yuxin said again.

"Legends are just legends after all. If you take it seriously, you will lose. What's more, it should be common sense to ascend into the ancient world and take away all the resources. And they can also leave some elixirs and weapon refining resources for the destined people, so

It’s already pretty good.” Gu Zheng said with a smile.

"All right!"

Lian Yuxin smiled sheepishly. Ever since she was forced to join Emei by Gu Zheng, she always felt that her IQ seemed to have dropped a lot when facing Gu Zheng. Many times, she blurted out words without even thinking about it.

.

"I've given you all the materials for refining the weapon. As for the jade slip, I think it's better to destroy it." Gu Zheng asked.

"Yeah, yeah, you really don't need the spiritual power of the twin immortals of Yingzhou." Lian Yuxin said with a slight blush.

The two immortals of Yingzhou are not righteous monks. One of their best methods is the 'tonic art'. Back then, they were like emperors on Koryo Island, and they harmed many women.

Moreover, the so-called Yingzhou Twin Immortals are just self-proclaimed. In everyone’s minds, they should be more appropriately called the ‘Yingzhou Twin Demons’! After all, the skills they practice are mainly evil arts.

Although Lian Yuxin also practiced evil arts, they were incomparable to the evil arts practiced by the Yingzhou Double Immortals. The evil arts she practiced were not harmful to the heavens and could be regarded as necessary for the profession of a weapon refiner.

Gu Zheng exerted force in his hands, and the Chuan Gong Jade was reduced to powder. He started to walk back, his brows slightly furrowed.

Although it is normal that there is nothing to gain from the treasure, Gu Zheng still feels a little uncomfortable in his heart. After all, this treasure was found by the weapon spirit through in-depth exploration at the cost of harming himself.

"I hope that island on the sea can give me some different gains, otherwise I will be so sorry for you."

Gu Zheng looked inside, looking at the small garden where the weapon spirit was. The weapon spirit, which was originally alive and kicking, was now lying on the big stone and sleeping. It had been like this since her spiritual mind returned.

"Actually, it's not bad. After all, you still harvested two high-quality ingredients from those two immortal cultivators!" The weapon spirit slowly opened its eyes and said very tiredly.

"You didn't fall into a deep sleep?" Gu Zheng said happily.

"Not yet. I am just repairing myself by closing my eyes. But now that the necessary repairs have been completed, I will fall into a seven-day deep sleep."

Qi Ling paused and slowly closed his eyes: "I'm so sleepy. You've been fine these past seven days."

"Don't worry, just go to sleep!"

Hearing the weak and sleepy voice of the weapon spirit, Gu Zheng felt a little uncomfortable. After all, this little girl had been with him since the day he picked up the Tie Immortal Token.

After leaving Yingzhou Mountain, Gu Zheng took Lian Yuxin and flew towards the island on the sea.

It has to be said that the area Qi Ling explored in two minutes was really huge. It took Gu Zheng and Lian Yuxin a long time to fly to the place Qi Ling mentioned.

There was a sea of ​​blue waves in front of him, and there was nothing strange at all on the surface, but Gu Zheng knew that he had not come to the wrong place, after all, the weapon spirit had left the mark in his mind.

"Is it really here?"

On the way following Gu Zheng, Lian Yuxin couldn't help being surprised even though she didn't want to be curious. She really couldn't imagine how Gu Zheng knew there was an island here!

Was it really detected using spiritual thoughts?

Lian Yuxin couldn't imagine what kind of spiritual thought it was that could first find the treasure of Bailu Lake and then fly to this place without her being aware of it at all and without affecting the battle.

Even with her spiritual exploration, she found nothing.

It's not surprising that Lian Yuxin couldn't detect the island-protecting immortal formation, and Gu Zheng couldn't detect it either, because this island-protecting immortal formation is a high-level island-protecting immortal formation.

Gu Zheng has seen islands with island-protecting fairy formations. There are Wufeng Island, Blood Tide Island, Ziyan Island, and Zhaoxia Island. The island-protecting fairy formations of these four islands, Wufeng Island and Blood Tide Island belong to the island-protecting fairy formations.

Intermediate Island Protection Immortal Formation. Ziyan Island, Zhaoxia Island, including islands that have not yet been visited, use advanced Island Protection Immortal Formation.

Intermediate island-protecting immortal formations, even if fog does not occasionally appear outside, can still be detected with the spiritual will of the realm of returning to the void. However, the high-level island-protecting immortal formation is different. With the cultivation of the returning to the void realm, it is impossible to detect it at all.

To discover its existence, even the divine will that transcends common sense based on ancient disputes will not work! If you want to detect its existence, you must have the extremely special divine will of the weapon spirit, or the divine will of the Golden Immortal realm.

When the Qi Ling Shen Nian explored the island, it had almost reached its limit, so it did not help Gu Zheng find a path through the island-protecting fairy formation.

"Use your magic weapon!" Gu Zheng said.

"Um."
