If a specific task needs to be completed to open this treasure chest, if you want to open the lock, certain conditions need to be met. If these conditions are not met, the treasure chest cannot be opened, and quest-related items often appear in the treasure chest.

Nie Yan was about to give up and think of other ways when he suddenly remembered the Magic Key in his backpack. He wondered if the Magic Key would work.

He took out the Magic Key from his backpack and aimed it at the lock. The Magic Key emitted a dazzling light and automatically changed shape according to the size of the lock, slowly shrinking.

The Magic Key accurately inserted into the keyhole.

Seeing this, Nie Yan was overjoyed. The Magic Key might be able to open this treasure chest!

After a while, about thirty seconds, a crisp system prompt sounded.

System: Treasure chest opening...8%...12%...

He didn't expect the Magic Key to be really useful. Nie Yan was ecstatic. This was a sub-legendary chest, and with such a high-level lock, the things inside should be extraordinary.

Hopefully it's not a quest item!

With a click, the treasure chest was opened, and a scorching heat wave spewed out, almost knocking Nie Yan off his feet.

Nie Yan stopped. The treasure chest revealed a blazing red light, and a powerful aura radiated out, making people feel frightened. He reached into the treasure chest and pulled out a large egg. This egg was wrapped in flames, all red, but Nie Yan's palm felt a strong and powerful heartbeat. He was sure that there was a living creature inside this egg.

-320, -316...

Blazing fire damage numbers floated above Nie Yan's head.

System: Are you willing to accept the quest to resurrect the Flame Fire Phoenix?

Nie Yan glanced at the system prompt, stunned. Inside this egg, there was a phoenix?

It was a flying mount. Nie Yan was moved. He didn't expect to get another flying mount.

"I got a pet egg, you take it." Nie Yan looked at Xie Yao. The difficulty of the quest to resurrect the Flame Fire Phoenix shouldn't be low, and it requires a certain amount of skill to complete. Moreover, pet eggs must be kept in the hands of those close to you.

In his previous life, Nie Yan had never heard of anyone getting a phoenix. This map was opened at levels eighty or ninety. It seemed that this sub-legendary treasure chest was added after the flying mount system was opened.

Nie Yan immediately had many associations. Since he could open a flying mount pet egg, many other players must have opened flying mount pet eggs as well. The popularization of flying mounts was an inevitable process.

"Don't you want it?" Xie Yao asked.

"I already have the Darkwing Dragon, and everyone can only have one pet." Nie Yan explained. This Flame Fire Phoenix egg couldn't be wasted.

"I see, then okay." Xie Yao nodded and took the Flame Fire Phoenix egg. As soon as she touched the flames from the pet egg, damage numbers of more than six hundred floated above Xie Yao's head. She quickly activated the quest to resurrect the Flame Fire Phoenix.

After accepting the quest, the scorching flames on this pet egg no longer caused damage to Xie Yao.

"After accepting the quest, fire resistance increased by more than 80 points." Xie Yao said to Nie Yan. Her current fire resistance had already reached more than one hundred and sixty. If she drank another bottle of high-level fire resistance potion, it could reach more than two hundred, which was amazing at this level. Even if she was directly sprayed by the magic of the Flame Giant, she would only take about 20% damage.

The Flame Fire Phoenix was a fire-type creature!

Nie Yan continued to grope in the treasure chest and pulled out a silver-white necklace. In the burning red treasure chest, a feeling of icy coolness came, making people feel peaceful.

Nie Yan's heart tightened suddenly. Just from the touch on his hand, he could feel that this thing was definitely not simple.

After he took out this necklace, the treasure chest turned into flames and disappeared.

He looked at the properties of this necklace.

Heart of Tranquility Necklace (Sub-Legendary): Special Item.

Properties: Wearing this necklace grants immunity to mental control from seduction, fear, and demon's voice within level eight.

Limitation: Limited to players with spirit below 1500.

"What's your spirit?" Nie Yan looked at Xie Yao and asked. It was the first time he had encountered equipment with such requirements. Those with too high spirit couldn't use it, but those with lower spirit could.

When players' spirit is below a certain level, the mental imprint attached to the Heart of Tranquility Necklace can affect you. When spirit is too high, the mental imprint on the Heart of Tranquility Necklace cannot affect you.

"Xie Yao, what's your spirit?" Nie Yan asked. This necklace appeared here, probably related to the quest to resurrect the phoenix. If Xie Yao could use it, it would be better to give this necklace to Xie Yao.

"My spirit is already 2300." Xie Yao looked at her own attributes and said.

"So high." Nie Yan gasped, exclaiming. Ordinary players at Xie Yao's level would be doing well to have around 1200 spirit, reaching 2300 was unimaginable. With such a high spirit, even without wearing the Heart of Tranquility Necklace, she could still be immune to seduction, fear, and demon's voice within level eight to a certain extent.

"Three pieces of my legendary set increase spirit." Xie Yao explained. Wearing three pieces of legendary equipment that increased spirit, it was impossible for her spirit to be low.

"I see." Nie Yan then remembered that the spirit bonus attribute of the Christina set was very excellent, far exceeding other similar equipment.

Since Xie Yao couldn't use this Heart of Tranquility Necklace, Nie Yan put it away. The effect on this necklace was still very practical, especially for melee units. Melee class players generally had lower spirit and were easily controlled by mental magic. Mental magic was an important means for magic class to deal with melee units.

The harvest was quite rich, especially the phoenix egg in Xie Yao's hand. If it could be hatched, the Ni Ren Guild would have another flying mount.

"Let's continue to grind the Flame Giants," Nie Yan said.

"Okay."

The two continued to grind the Flame Giants to level up. By grinding the Flame Giants like this, the contribution values of the two increased rapidly. It was estimated that after a few days of grinding, Xie Yao's contribution could buy a plot of land.

They had to grab more Hilton Fortress land as soon as possible, especially those prime locations. In the future, these plots of land would be golden egg-laying chickens!

Nie Yan continued to lure the Flame Giants, and the two continued their monotonous monster grinding. Using that terrain, killing the Flame Giants was not difficult, and Xie Yao's fire resistance had greatly increased, so she was even less afraid of the Flame Giants' magic attacks.

After about five hours, a system prompt came. Nie Yan leveled up to ninety-four. After going to Hilton Fortress to receive additional experience rewards, he estimated that he could level up to about 50% of ninety-four.

"How much contribution do you have?" After another Flame Giant was killed, Nie Yan looked at Xie Yao next to him. In the narrow tunnel, Xie Yao's eyelashes were high, and her black eyes, like black gems, sparkled with charming light. From the side, he could clearly feel Xie Yao's moving curves.

"Let me see." Feeling Nie Yan's gaze, Xie Yao lowered her head shyly and said, "About more than twenty thousand."

Xie Yao's contribution value accumulated very quickly. If ordinary players were to team up to grind monsters, it would take at least five or more teams to safely kill a monster. The contribution value obtained by killing a monster would be divided among each player, leaving very little. However, Nie Yan and Xie Yao grinding monsters like this, the contribution value obtained by killing the Flame Giant was only split between two people, which was quite considerable.

The contribution value that Xie Yao and Nie Yan obtained by grinding a Flame Giant together was more than fifty times that of ordinary players participating in a team to kill a monster. Plus, the two's monster grinding speed was also not bad, so the contribution value soared like a rocket.

"It's estimated that by tomorrow, you'll be able to buy a plot of land in Hilton Fortress," Nie Yan said. Every time a plot of land was bought, it meant a large sum of money was coming in.

"I'll go pick up the items dropped by the Flame Giant," Xie Yao said, walking forward. She had to pass by Nie Yan, and it was very difficult to turn around in the narrow passage, so some physical contact was inevitable.

A faint fragrance drifted into his nose. Looking at the delicate and charming Xie Yao next to him, Nie Yan felt affection in his heart. Through the thin magic robe, Nie Yan seemed to be able to feel Xie Yao's delicate skin.

This was a virtual world, not reality. In the virtual world, Xie Yao, wearing a light blue magic robe, was full of a dreamlike beauty.

Nie Yan reached out and grabbed Xie Yao. In his mind, he couldn't help but think of the underground secret chamber in his previous life. He wondered how it was doing, whether it was still the same as in his previous life.

In the narrow passage, Xie Yao could hear Nie Yan's heavy breathing, and her heart suddenly panicked. In her world, Nie Yan had occupied an increasingly important position. The relationship between the two had been confirmed, but every time she got close to Nie Yan, she couldn't help but feel nervous in her heart.

Xie Yao's fair and flawless pretty face was close at hand, and some uneven breathing revealed the tension in her heart.

"Nie Yan..." Xie Yao whispered reproachfully. To avoid falling into Nie Yan's arms, she supported herself on the rock wall with her hands, but the feeling coming from her chest still made her body stiffen.

Nie Yan's right hand was placed dishonestly on Xie Yao's chest. On the soft and smooth silk robe, there was a strange touch. Xie Yao's bust was very full, so the bra inside was just a thin layer of cloth, and it felt solid and round to the touch.

This was the first time Nie Yan had such intimate contact with Xie Yao in the game, and it felt different. Standing in front of Nie Yan at this time was Xie Yao, and also Yao Yao. The two were the same person, but they had different stories with Nie Yan.
