Douluo Continent: Dragon Shadow Rebirth

As Qin Feng and his companions entered the underground space, the surrounding scene became more bizarre and mysterious. This place seemed to be a forgotten world, with ancient runes and patterns engraved on the surrounding stone walls. These patterns seemed to record some important history, but due to the long time, many of them were blurred.

"These runes are somewhat similar to the sealing techniques we saw in the academy before. They may be related to the Shadow Dragon." Ye Li observed for a while and put forward her own guess.

Qin Feng nodded: "No matter what is hidden here, we must find out the truth. This may be the key to our defeat of the Dark Cult."

They moved forward cautiously in the underground space, and the air around them was filled with a suffocating sense of oppression. Every step they took, it seemed as if countless pairs of eyes were staring at them in the dark, making them feel extremely uneasy.

Suddenly, a wide open space appeared in front of them. In the center of this space stood a huge altar, and above the altar was a huge dark crystal, which seemed to contain some powerful power.

"This crystal... is the source of the dark power!" Qin Feng said in surprise. He felt an extremely powerful spiritual power fluctuation surging in the crystal.

Ye Li carefully observed the altar and the crystal and found that there were complicated sealing runes engraved on the altar. These runes were obviously used to suppress the power in the crystal.

"This crystal may be some extremely powerful dark matter. Its power is enough to destroy the entire world." Ye Li's voice was filled with a hint of fear. "We must find a way to destroy it, otherwise the consequences will be disastrous."

Qin Feng also realized the seriousness of the problem, and he clenched the Dragon Shadow Sword, ready to attack. However, when he tried to approach the crystal, the runes on the altar suddenly emitted a strong light, and a powerful counterattack force shook him back.

"This crystal is protected by a powerful seal. We must break the seal before we can touch it." Ye Li analyzed. She began to study the runes carefully, hoping to find a way to crack it.

Under Ye Li's guidance, Qin Feng and his companions began to try to destroy the seal runes on the altar. However, these runes were extremely complex, and every time they destroyed a part, the dark power in the crystal would counterattack, making their progress extremely slow.

"These runes seem to be closely connected with the power of the crystal. We can't act rashly, otherwise it may cause a greater disaster." Ye Li said with a frown. She knew that this mission was extremely difficult.

Just as they were concentrating on breaking the seal, the mysterious figure suddenly appeared in the underground space. His figure was like a ghost in the dark night, quickly moving to the front of the altar and blocking Qin Feng and his companions' way.

"You stupid guys actually tried to destroy my masterpiece. You're really courting death!" The mysterious figure's voice was filled with endless anger and hatred.

Qin Feng clenched the Dragon Shadow Sword and said coldly: "We won't let you succeed, this crystal must be destroyed!"

The mysterious figure let out a sinister laugh, and then released a powerful dark force, trying to completely devour Qin Feng and the others. The entire underground space was instantly shrouded in darkness, as if it had turned into an endless hell.

"Everyone be careful, he is very powerful!" Ye Li quickly released the Frost Fox and used the cold air to resist the invasion of the dark power.

However, the power of the mysterious figure far exceeded their expectations. Despite their best efforts, the dark force continued to erode their defenses, as if it would swallow them up completely at any time.

Facing such a powerful enemy, Qin Feng decided to go all out. He concentrated all his spiritual power and raised the power of the Dragon Shadow Sword to its extreme, with dazzling lightning flashing on the sword.

"I must defeat you!" Qin Feng roared, then swung the Dragon Shadow Sword, hitting the mysterious man's vital points.

The mysterious figure obviously did not expect Qin Feng to have such a powerful counterattack. His defense was instantly defeated by the power of thunder and lightning. He was hit by the sword light and let out a scream.

However, the mysterious figure did not fall down. His figure kept changing in the darkness, as if he turned into countless black shadows, dissolving Qin Feng's attack into nothingness.

"This guy is simply a monster!" Chu Tian shouted anxiously. His Storm Wolf was almost unable to move in the dark and seemed extremely passive.

Ye Li also felt that the situation was not good. She knew that if they continued like this, they would probably be dragged into a desperate situation. She quickly analyzed the situation and decided to change her strategy.

"We must disperse his strength and cannot continue to concentrate the attack!" Ye Li reminded loudly, and her frost fox began to release powerful cold air, trying to separate the dark forces.

Qin Feng realized Ye Li's intention, and he immediately adjusted his attack method, concentrating his strength to launch attacks in multiple directions at the same time, trying to force the mysterious figure to reveal a flaw.

Under the full counterattack of Qin Feng and his companions, the mysterious man's power was gradually weakened. Although he was still fighting back frantically, his attacks were no longer as sharp and accurate as before.

Just as the battle reached a stalemate, the crystal on the altar suddenly burst into a strong light. The light seemed to penetrate the darkness and illuminate the entire underground space.

The mysterious man obviously felt the power. His face suddenly changed and he looked extremely terrified: "No, this is impossible!"

Qin Feng felt the extremely powerful force contained in the light, and he knew this was their chance. He concentrated all his spiritual power and launched the ultimate attack of the Dragon Shadow Nine Styles again. The sword light struck the core of the mysterious figure like a thunderbolt.

Under this fatal attack, the mysterious figure finally couldn't hold on. His body turned into nothing under the impact of thunder and lightning, and the entire underground space instantly returned to calm.

Although the mysterious figure was defeated, the crystal on the altar still exuded a powerful dark force. Qin Feng knew that they had to destroy it immediately, otherwise these forces might condense again.

Ye Li quickly walked to the altar. She found an ancient sealing technique in her notebook and decided to use it to seal the dark power in the crystal.

"I need your help. This sealing technique requires a lot of spiritual power support." Ye Li said to Qin Feng and the others, and her Frost Fox was also assisting in casting the spell.

Qin Feng, Chu Tian and Zhang Meng did not hesitate at all, they immediately injected their spiritual power into Ye Li's sealing technique. With the injection of spiritual power, the runes on the altar began to emit a dazzling light, and the dark power in the crystal was gradually suppressed.

"Keep trying, we'll almost succeed!" Ye Li was concentrating on performing the sealing technique, and beads of sweat had already appeared on her forehead.

With everyone's full support, the sealing technique was finally completed. The crystal on the altar made a final low roar, then shattered into countless fragments, and the dark power completely dissipated into the air.

As the crystals were destroyed, the entire underground space began to shake violently, as if it could collapse at any time. Qin Feng and his companions knew they had to evacuate quickly, otherwise they would be trapped here.

"Hurry up, this place is going to collapse!" Qin Feng shouted, leading everyone to rush out of the underground space quickly and run desperately along the passage they came from.

Although they were exhausted, their survival instinct made them dare not relax at all. At the moment when they were about to escape from the passage, the underground space behind them finally collapsed completely, and the entire ground shook violently, as if the earth was roaring.

"We... finally got out." Zhang Meng said while panting. His giant rock bear was also growling beside him, looking extremely tired.

Qin Feng and his partners finally breathed a sigh of relief. They knew that this mission was extremely difficult, but they finally completed it successfully.

After confirming safety, Qin Feng and his team decided to return to the Soul Master Academy immediately and report the results of this mission to Vice President Feng Jian.

Although they successfully destroyed the source of the dark power, everyone's heart was filled with mixed emotions. Qin Feng felt his inner growth and maturity, and he knew that this battle gave him a deeper understanding of power and responsibility.

"Although we won, there are still more challenges waiting for us ahead." Qin Feng looked into the distance, his heart full of thoughts about the future.

On their way back, Qin Feng and his companions decided to continue to work hard on their training, to improve their strength and mind, and to be better prepared for future battles.

They know that no matter how difficult the road ahead is, they will keep going and protect everything they cherish.
