Heaven-defying Upgrade System

When Si Yin thought of this, she rushed over and gritted her teeth. After circulating the Genuine Qi in her body, her aura suddenly rose. However, with Si Yin's participation, the situation on the battlefield did not change much. Si Yin's cultivation base was not low either, but there were close to a hundred people with the same cultivation base. Therefore, she could not see anything with the addition of one more person. It was just that the momentum of her fighting with her life on the line was constantly affecting the people around her. It was as if it had ignited their fighting spirit.    

    

Even though Si Yin had already figured out why Liu Fei did not attack, in her heart, she was still blaming Liu Fei. After all, the invasion of the Black Flame Clan wasn't a small matter. Liu Fei wanted to stay in the White Wood Clan. He should at least try his best. If Liu Fei didn't have any abilities, it would be fine. However, Si Yin had seen Liu Fei's strength with her own eyes. That was a powerful strength that could fight Lava Warrior alone. But now, he did not care about anything. He was too cold-blooded!    

    

Liu Fei looked at the guardians who rushed forward, and then his eyes stared intently at the Black Flame Clan invaders who were fighting with the guardians. The corner of his mouth curled up slightly. If Liu Fei really did not intend to help, he would not need to come down. If he was only worried about Si Yin's safety, he could actually just watch from the aircraft.    

    

The reason why Liu Feizhi said that he didn't help was because he hadn't seen the true strength of these Black Flame Clan invaders yet.    

    

Those intruders from the Black Flame Clan looked like ferocious wild beasts, but the Black Flame Clan also had their own intelligence. They saw that Liu Fei didn't attack, but it didn't mean that they didn't notice him. They could sense a mysterious force coming from Liu Fei's body, so they didn't provoke him. Instead, they focused all their energy on these protectors.    

    

The battle was getting more and more intense and chaotic. These invaders of the Black Flame Clan were not afraid of death, as if they were killing machines. Their team had sneaked into the White Wood Clan, but they didn't encounter any powerful warriors in the Divine Wind Department. They were only the guardians of the group, which was why they were so powerful. If they encountered any powerful warriors, they wouldn't be able to hold on for long.    

    

However, the purpose of these bastards from the Black Flame Clan was to send themselves to their deaths. They were the men of sacrifice. Even if they were to die, they would create chaos in the White Wood Clan. This caused the people of the White Wood Clan to panic. If the effect was good... It would be even more because of the large-scale invasion! Therefore, they seemed to be especially crazy. Compared to them, the guardians were different. After all, these Guardians did not have the determination to die, so they always had scruples. When it was a matter of life and death, they would instinctively start to shrink back. This way, their momentum wouldn't work.    

    

"Si Yin, don't rush too fast. It is best to retreat and hold them back!" The person who spoke seemed to be the leader of Scouting Group. Looking at the fearless Si Yin, he could not help but call out to her.    

    

The leader was also frightened by Si Yin's desperate spirit. What she did now basically meant that she had bid farewell to the team and left the command.    

    

However, Si Yin understood in her heart that it was not that she was unwilling to follow orders. She clearly realized that if someone retreated, everyone would retreat. This way, the morale of the team would be gone, and they would definitely lose this battle. At that time, the Black Flame Clan would become more and more arrogant. Not only would the defense line of the defenders collapse, but they would also lose this battle. In this way, the Black Flame Clan's plan would succeed. The success would cause panic in the White Wood Clan, and the consequences would be unimaginable.    

    

Therefore, in a battle, a hero had appeared. It's often the key to a fight. Because only the spirit of a hero could guide everyone to bravely and fearlessly fight to the death. Si Yin already had an understanding in her heart. Even if she died here, she must awaken everyone's fighting spirit!    

    

At this moment, the distance between them and the intruders of the Black Flame Clan was getting closer and closer. The Sacred Origin Spear in Si Yin's hand was no longer flexible enough. She simply threw the Sacred Origin Spear to the side and pulled out a Longsword. This Longsword was given to her by Liu Fei last night. He realized that Si Yin's close combat attack would be a weakness. Liu Fei gave her a magic weapon grade Longsword, and at the same time taught her the Imperial Wind Sword Technique that Gao Yuming practiced.    

    

Although Si Yin's understanding of the Imperial Wind Sword Technique was not complete, at this time, she did not care about that and waved the sword technique that she was not familiar with. Streams of sword qi shot out and instantly formed a wind barrier. It enveloped Si Yin within. Following which, the guards behind her picked up the Sacred Origin Spear one after another. They kept shooting at the monsters of the Black Flame Clan, shooting out beams of white light. However, with the power of the holy origin spear alone, it was unable to push back the crazy monster.    

    

A few experts from the Scouting Group and the Wind Catcher Team looked at each other. They immediately rushed forward. They were not cold-blooded animals. Of course, they would not watch Si Yin die for nothing. Their plan was to bring Si Yin back. However, when they rushed over, they realized that the huge force of Black Flame Clan couldn't resist at all. Moreover, Si Yin was already surrounded by these monsters. If they wanted to save Si Yin, they had to break through the encirclement of these monsters.    

    

But rushing in might be easy, but once he rushed in, he would be in grave danger. It would be difficult for him to come out again!    

    

Even though Si Yin was surrounded by the monsters of the Black Flame Clan, the Imperial Wind Sword Technique that she was using was not to be trifled with. In this period of time, Si Yin relied on her high fighting spirit. Her agile movement technique had unleashed a shocking combat strength. But as time passed, Si Yin gradually felt that the Genuine Qi in her body could not hold on any longer. And this was even after cultivating the True Purple Cloud Spell. If it was the low level inner force mantra from before... She was afraid that the Genuine Qi would have been completely used up long ago.    

    

Si Yin felt a sense of fatigue coming from her body. Her arm felt as if it was pressed down by a huge rock. It was incomparably heavy, as if every swing of the Longsword was incomparably difficult.    

    

Seeing that Si Yin could not hold on any longer, those crazy Black Flame Clan's people's imposing manner suddenly became much stronger. Each of them looked at Si Yin with a ferocious smile. They waved the giant hammer in their hands and roared as they smashed towards Si Yin.    

    

However, when the cold light in the eyes of the Black Flame Clan's monsters was fully displayed, suddenly, an even more dazzling silver light covered their eyes. Under this silver light, they couldn't see anything clearly. Although it was only for a moment, they were surprised to find that... The spiritual energy in his body is diminishing.    

    

At the same time, a member of the Black Flame Clan let out a miserable cry. His eyes were blood-red as he stood on the spot, but a huge bloody hole appeared on his body in an instant. In the bloody hole, arcs of lightning crackled and flickered. The air was filled with the smell of burnt flesh.
