The two of them walked into the hall and found that there were four extremely thick pillars in the Pavilion of All Affairs. There were many words floating and flashing on them. Each pillar was surrounded by cultivators, and some of them were even flying in the air.

Li Jinzhi looked at them one by one and found that the first pillar was surrounded by cultivators in the Qi Refinement stage, the second pillar was surrounded by cultivators in the Foundation Establishment stage, and the third pillar was occupied by cultivators in the Golden Elixir stage. There were fewer people around the fourth pillar, but they were all in the Yuanying stage.

Ye Cheng pointed to the pillar with fewer people and said through voice transmission, "That place is surrounded by cultivators in the Yuanying stage. I think the missions given out must be of the Yuanying stage."

Li Jinzhi nodded. "That's true. I think the missions are more difficult." The rewards were also more generous.

Since they had decided to rely on missions to comprehend divine powers, the two of them naturally could not accept low-level missions. They walked straight to the fourth pillar and began to look for missions that were suitable for them.

But soon, the two of them discovered something.

The missions on the pillars were more or less the same. They were all about going to the Netherworld Cave to kill insects. As for what kind of insects they were, each mission was different.

The Netherworld Cave?

Li Jinzhi and Ye Cheng looked at each other and saw the confusion in each other's eyes. All the maps and information did not mention the Netherworld Cave.

Even the steward who rented the cave abode earlier did not mention anything about the Netherworld Cave.

Looking at the various kinds of insects mentioned in the mission, the two of them fell into deep thought. It seemed that this Earth's Core City, which was separated from all forces, had a very obscure secret.

"Well, are the two of you also here to accept missions?" A male cultivator's voice sounded behind the two of them.

The two of them looked back and found that it was a tall young man with a square face. He looked simple and honest, but he was a real Beihan Yuanying cultivator.

Seeing that the two of them did not answer, the man repeated himself. "Are the two of you planning to accept missions?"

"We're just taking a look."

Ye Cheng answered coldly. Then, he turned his head back and sent a voice transmission to Li Jinzhi. "Our divine abilities are too secretive. It's not suitable for us to bring other cultivators along."

Li Jinzhi naturally knew the pros and cons. He nodded and said to the man, "The two of us are just here to see if there are any missions worth taking. We don't plan to accept them immediately."

That person seemed a little disappointed, but he did not pursue the matter any further. "Then I won't disturb you any further." Then, he turned and walked towards another Light Source cultivator.

As soon as that person left, a Hiroyuki beside Li Jinzhi sneered, "Tsk, he's just worried that he won't be able to complete the mission on his own. As a Yuanying cultivator, he's shamelessly trying to pull strings."

Then, the man turned to look at Li Jinzhi and said, "You two must not collude with the cultivators of the Moon Palace. They are really notorious people!"

Li Jinzhi had a plan in mind, so he followed the man's words and asked, "Oh?

What did they do? "

After a pause, he added, "The two of us have been in seclusion for too long. When we came out, we found that there were many strange creatures around us."

"Sigh, Fellow Daoist, you don't know. Let's not talk about what happened outside the Earth Core City. An extremely hateful thing happened in the Earth Core City."

The cultivator's face was filled with righteous indignation. "We have always treated foreign cultivators fairly. However, last time, a group of Golden Elixir cultivators from the Friar Of The North roped in the Moon Palace cultivators to go on a mission together. In the end, the Friar Of The North returned alive, and the Moon Palace cultivators all died."

"But that doesn't mean anything, right?

It's normal to die during a mission, "Li Jinzhi asked with a frown.

"It's nothing, but one of the Hiroyuki who participated in the incident came back. He said …" The cultivator leaned close to Li Jinzhi's ear and whispered, "A group of Hiroyuki was used as bait by the Friar Of The North and led to a dangerous place for the sake of an extremely powerful Demonic Core of a female insect …"

Before he could finish speaking, Li Jinzhi's collar was pulled back. He turned around and saw that it was indeed Ye Cheng.

His slender eyebrows were tightly knitted, and his eyes were filled with dissatisfaction. "You're too close."

Ye Cheng was very confused. Recently, his mood had been very strange. He did not like Jingzhi to have anything to do with anyone other than him. If he got too close, it would look awkward.

This kind of emotion was even more obvious after leaving the bottom of the sea.

He clearly knew that there would be no one closer to Jingzhi than him, but he still felt that something was not enough.

What was not enough?

Li Jinzhi was not angry after being pulled away by Ye Cheng. The distance just now was indeed too close. If the other party suddenly attacked, he would not be able to avoid it. In the cultivation world, he had to be vigilant at all times.

And he was not interested in the grudge between the Hiroyuki and the Friar Of The North. After grabbing a few words, he asked, "Female insect?

Fellow Daoist, to tell you the truth, the two of us are not native cultivators of the Earth's Core. It's just that the war outside is about to start. The two of us are ascetic cultivators, and we don't want to get involved, so we came to the Earth's Core City. "

"Hey, I see." The cultivator was the only one who was stunned. He smiled and said, "Actually, Fellow Daoist wants to ask about the Netherworld Cave, right?"

"It's the Netherworld Cave. I've never heard of the Netherworld Cave in other cities." Li Jinzhi climbed up the pole.

"The Netherworld Cave is a secret of the Earth's Core City. Fellow Daoist, do you have a cultivator token in your hand? This token is used to protect this secret."

The cultivator took out a light yellow token from his bosom, "After leaving the Earth's Core City, this token will automatically erase the cultivator's memories of the Netherworld Cave. Therefore, the outside world does not know of the existence of the Netherworld Cave."

"Why is that?" Ye Cheng frowned and asked. He always felt that the existence of the Earth's Core City was related to the Netherworld Cave.

"The existence of the Earth's Core City is to guard the Netherworld Cave."

The cultivator's face was full of mystery, "There are tens of thousands of Zerg with different appearances living in the Netherworld Cave. If there is no one guarding it, this Guangyuan Desert will be occupied by Zerg."

Tens of thousands!

Li Jinzhi and Ye Cheng looked at each other in shock. They were extremely shocked. It turned out that there was such a secret hidden under the Guangyuan Desert!

Ye Cheng transmitted his voice to Li Jinzhi, "No wonder the resources under the desert are so poor. There are no spiritual herbs, no minerals, but they can condense so much Yuanying under such difficult circumstances."

Li Jinzhi naturally understood the key point. If he could use the demon insects to train his divine ability, it would naturally be the best.

Moreover, the shell of the demon insects was hard and could be used to refine weapons. The demon insects' demon cores could be used to refine medicine. If he could not consume it himself, he could sell it for money.

After making up his mind, the two thanked the enthusiastic cultivator and began to carefully choose the mission.

The two of them had just started to come into contact with Zerg, so they did not dare to be too rash. They chose two missions with low risk and ordinary pay before accepting the mission.

The manager of the All Affairs Pavilion was a rather old Foundation Establishment cultivator. He raised his eyelids and glanced at the two of them. After taking the yellow token, he swept it in the air and said lazily, "There are two mid-rank missions. After completing them, you can get ten mid-rank spirit stones. Do you want to buy a map of the Netherworld Cave?" He casually threw out three or four jade slips of different colors.

"Are these all map jade slips?" Li Jinzhi picked up one and asked.

"There are also Zerg types, Zerg distribution, Zerg death door. These are the experiences accumulated by cultivators in the Netherworld Cave in the past years. They can greatly increase the chances of survival. Of course, you can buy them or not."

The old man saw that the two of them were asking about these jade slips and finally became a little spirited, "Each one only costs five low-rank spirit stones."

"Then give me one of each." Li Jinzhi took one of each jade slips and turned to leave after letting Ye Cheng pay.

The two of them were not in a hurry to go to the Netherworld Cave. Instead, they returned to the cave they rented earlier. The cave was extremely empty. There was only a table and two chairs. There was not even a bed.

After the two of them entered, they did not set up anything or sense the surrounding spiritual energy. After sitting down on the chairs casually, Li Jinzhi poured the purchased jade slips on the ground. Just as he was about to pick up the jade slip with the map recorded on it, Ye Cheng grabbed his wrist.

"I'll look at this and the Zerg distribution. You only need to look at the Zerg types and Zerg death door." Ye Cheng placed the purple and blue jade slips in front of Li Jinzhi.

Li Jinzhi looked at the two jade slips in front of him and asked, "Why?"

Ye Cheng's hand that was holding the jade slips paused. He looked at Li Jinzhi strangely and asked, "Do you think that with your sense of direction, you can find the direction in the dark Netherworld Cave and identify the Zerg distribution?

Hmm? "

Li Jinzhi was speechless for a long time. He silently picked up the purple jade slip and placed it on his forehead. Then, he closed his eyes and did not speak.

Ye Cheng looked at him and the corners of his mouth curled up slightly. If he mastered all the terrain of the Netherworld Cave, then Li Jinzhi would probably not be able to leave him.

After all, he would get lost.

After an incense stick of time, Ye Cheng took off the jade slip on his forehead and could not help but fall into deep thought.

Li Jinzhi waited for the time it took to brew a cup of tea before he took the jade slip.

The two of them looked at each other and saw the seriousness in each other's eyes.

"The Netherworld Cave is divided into five levels. The area of each level is incomparably vast. The lower you go, the stronger Zerg's ability. No cultivator has ever gone to the lowest level." Ye Cheng frowned and said.

"There are really tens of thousands of Zerg types. It's not an exaggeration. Moreover, the death doors are all different. Some can spray poisonous fog, some can release parts.

Some can create illusions, and some can even release large areas of corrosive objects. "

Li Jinzhi's face was also full of thoughts. "Zerg's reproduction speed is extremely fast. If not for cultivators going in to kill them all year round, the consequences would be unimaginable."

"Although there are many of them, after so many years, Zerg and cultivators have reached a delicate balance. Hiroyuki needs monster cores, Zerg needs nutrients." Ye Cheng said coldly, "The Heavenly Dao is fair."

"Yes."

Li Jinzhi naturally understood the pros and cons. He stood up and said to Ye Cheng, "There are no mountains of knives or seas of fire below. Since the two of us are here, we have to go in and explore."
