"Finally got it."

"I didn't expect to find such a great bargain! A Demonic Marrow Diamond that's as valuable as the Demon Emperor's blood and essence. Hahahaha."

The moment he paid the money and got the things, Ling Tian was secretly delighted. In order not to arouse suspicion, he walked around inside calmly for a long time before slowly leaving. After leaving the inner layer of the Wanjie Chamber of Commerce, the outside was still so lively, so he didn't stay for too long and walked out directly.

Just as he was about to leave, a familiar aura startled Ling Tian. He turned around and looked. Although the girl had been modified a bit and looked very different from her original cute appearance, the aura remained unchanged. He then excitedly sent a voice message, "Senior Sister!"

Song Yulan's delicate body trembled, and she felt confused again when she looked at the man with a strange face.

Ling Tian was afraid that he wouldn't believe him, so he told him some things that only they knew. As Song Yulan listened, she could no longer hold back her tears.

"Senior Sister, this is not the place to talk. Come with me."

The two walked out of the dark abyss one after the other, and then turned into the nearby deep mountains and old forests. With Ling Tian there, even if there were a few uninvited guests following them, they could easily deal with them, erased all traces, found a desolate and secluded place, set up a formation, and released hallucinogenic butterflies to strengthen the defense of the illusion.

"Junior brother, it really is you, wuwu..."

Song Yulan could no longer hold back her tears, and she hugged Ling Tian and burst into tears. It took her at least a quarter of an hour to calm down.

"Don't be sad, Senior Sister. The dead are gone. We should be stronger and take revenge one day."

"Ah, it's easier said than done. I'm so lucky to meet you again. I forgot to tell you that the eldest sister also survived, but... she suffered serious injuries. I'm afraid she won't be able to become an immortal in this lifetime. She was also poisoned and I'm afraid she won't survive more than a month."

"Then where is the senior sister? Take me to see her. Maybe there is a solution."

"Okay, the elder sister will be very happy to see you."

Song Yulan took Ling Tian all the way and did not arrive at their hiding place until dawn the next day.

"Big Sister, look who's here."

"Big Sister, Big Sister..."

Before Song Yulan came forward, Ling Tian had already arrived at Murong Xue's side, quickly stuffed a pill into her mouth, and used his spiritual sense to check her physical condition.

After a few breaths, Ling Tian frowned and asked, "It turned out to be the Soul-Eroding Bone-Dissolving Poison. This is a ghost cultivation technique. How did Third Senior Sister and Eldest Senior Sister get poisoned?"

"At that time, we were hunted to the border of Liang State. Master and Second Senior Brother fought desperately to stop the pursuers. We were also seriously injured. In our eagerness to escape, we unknowingly fell into an unknown tomb group. At first, nothing happened, until we were practicing and recovering, and an accident happened. Dozens of ghosts emerged from the tombstones and directly attacked our souls. Senior Sister used her secret technique to kill nearly half of them before escaping with you and me. However, we were hit by a black light on the way out. Not long after, this happened. I tried everything to expel it, but it was unsuccessful. It's all my fault. If it weren't for me..."

"Don't blame yourself, it's none of your business. Third Senior Sister, please wait aside. I'll remove the poison from Senior Sister first."

"Junior brother, do you have a solution?"

Ling Tian’s words made Song Yulan excited. She felt so guilty.

"Although it's quite complicated, it should be fine. Stand back for a moment. Be careful not to get contaminated by the poison when it's forced out."

Although the Seven-Colored Divine Flame has the magical effect of restraining poisons, Ling Tian still dares not be careless. Moreover, the poison has already penetrated into Murong Xue's bone marrow, so he needs to be extremely careful.

After nearly an hour, Ling Tian was sweating profusely and was clearly exhausted, but his face was filled with joy. "This poison is truly powerful, but fortunately, the Seven-Colored Divine Flame can control it."

"Junior brother, what's wrong?" Song Yulan asked anxiously.

"The situation isn't too bad, but it'll take quite a while to completely eliminate it, and this place isn't suitable for long-term living. So, let me stabilize Senior Sister's injuries first, and then we'll go to Beidan City."

"Well, then it's as you said."

Ling Tian rested for a while and then helped Murong Xue remove the poison again.

Three days later, Murong Xue's injuries and poison were stabilized, and she woke up from her coma. When she saw Ling Tian again, she cried with joy and excitement. Song Yulan cried too. Ling Tian had to work hard to calm both of them down.

"Beidan City is just ahead."

After more than a month, Ling Tian and the other two had arrived at a ramp not far from Beidan City. From a distance, a huge city wall appeared in their eyes.

After exiting the ramp, there is a three-meter-wide road leading directly to the city gate. It is evening now, and there are not many pedestrians on the road.

After a quarter of an hour, the three of them arrived at the city gate. At first, they didn't feel anything, but when they got closer, they felt how small they were. Looking up, they saw that the city gate alone was ten feet high, and the entire city wall was probably more than thirty feet high.

The soldiers guarding the city were all in the Foundation Establishment stage, and their captain was even in the middle stage of the Core Formation stage. Upon seeing Ling Tian and the other two arrive, they suddenly became energetic.

"You three, come here and pay the city entry tax, ten low-grade spirit stones each, and show us your residency certificates."

"Sir, this is our first time here and we haven't applied for a residence permit. How do we get one?"

Ling Tian lowered his posture and kept a low profile in other people's places.

"First time?"

The leading man already knew that this was their first visit, otherwise he would not have called out to the three of them.

"Just come to me and apply. There are three options. The first is a temporary residence permit, valid for seven days and costing one hundred spirit stones per person. The second is a long-term residence permit, valid for one year and costing one thousand spirit stones per person. As for the last one, a permanent residence permit is required for residents of Beidan City. You have to pay a one-time fee of thirty thousand spirit stones and rent a house or cave dwelling for at least one hundred years."

"I wonder what suggestions you have, sir?"

Ling Tian sent a storage bag of spirit stones over without leaving any trace. It wasn't much, only 500 pieces. This amount would not make the other party dislike you or make him think that you are a rich coward.

The man smiled with satisfaction and said, "My suggestion is to apply for a permanent residency. As long as you obtain a resident token, you can enjoy a 5% discount on all purchases at all stores in the city. There are no entry restrictions for various high-end auction clubs. You also have the right to operate a store and are protected by our Beidan City Allied Forces."

"I wonder what the difference is between a cave and a house?" Ling Tian asked again.

Duofang didn't mind explaining the differences to Ling Tian and the others in detail. Simply put, it was the difference between a residential complex and a villa complex. Ordinary houses were located within the city, which was convenient but lacked privacy, lacked a spirit gathering array, and had average spiritual energy. Cave dwellings, on the other hand, were located within a massive, ten-thousand-foot-tall mountain in the east. They were categorized into three levels: first, second, and third, with third being the lowest and first the highest. The higher the level, the richer the spiritual energy. However, the price difference was enormous; a first-level cave dwelling cost 10,000 low-grade spirit stones per year.
