Long Yuxue heaved a sigh. Even if she had a platoon, purging this place of abyssal creatures was not something that could be done in a short while. However, Tang Wulin had relied solely on his spirit soul and accomplished just that in such a short period of time. It was beyond belief!

Just how powerful was his strength? Up till now, he had not even used his battle armor to fight. Would that not mean that he would be more terrifying if he had his battle armor on?

Tang Wulin leaped into the node. He did not retract the Goldsong. Instead, he pressed forward quickly. He reached the next tunnel and entered it swiftly.

The Goldsong was like Tang Wulin's eyes. What it saw, Tang Wulin could naturally see as well.

Light flashed in the tunnel and the Goldsong was already inside. The surprising thing was that the tunnel's interior was empty. There were no abyssal creatures inside.

"Wulin, that's about it. It's your first time here, so it's best not to go too deep. Throngs of abyssal creatures will appear inside the abyssal tunnel at random times. If a large group of abyssal creatures appeared, what with the few of us, it's"

She had not finished her sentence when Tang Wulin suddenly stopped in his tracks. "I think you're right."

Low roars accompanied the escalating air flow which came from inside the tunnel.

When she heard the sound, Long Yuxue's expression changed drastically!

"This is bad. It's really an abyssal tide! Run!" Before she had even finished speaking, she pulled on Tang Wulin as she turned around and ran out of the tunnel.

Tang Wulin did not have a thorough understanding of the abyssal tunnel. However, he was not so arrogant as to think that he could hold back the abyssal tide with his own strength. With that, he turned around and without hesitating ran after Long Yuxue.

Long Yuxue was a little slow. Tang Wulin hooked her slender waist with his right hand and unleashed his two-word battle armor at the same time. His pair of golden wings unfurled behind him.

The Goldsong turned into a beam of golden light and entered Tang Wulin's body. Tang Wulin flapped his wings mightily. At the same time, he commanded his entire body's blood essence energy to surge toward his Dragon Moon battle armor behind him. He flew toward the way they came in, like a beam of flowing golden light at blinding speed.

Long Yuxue exclaimed in shock. She then noticed being held in an embrace. Because of the high speed, the strong headwind made it difficult for her to keep her eyes open. However, she felt strangely at ease. What tremendous speed! Under his battle armor's full throttle, it seemed that he was not any slower than the Mo Mei.

The rumbling sound kept coming from behind, and it sounded like it was getting closer. Tang Wulin felt like it was a giant, destructive vortex that was closing in on him from behind as if it was going to devour them all.

Such a feeling was definitely uncomfortable. The sense of danger compelled him to increase his speed to the maximum as he passed through the cavern in front of him.

He finally reached his starting point, the place where he first came in. It was where the Blood God Army had formed a line of defense.

"It's an abyssal tide! Everyone, be careful!" shouted Tang Wulin.

In truth, when he charged out, he noticed that this node was already filled with energy. Scores of giant, light shields were already erected. All the soul cannons were filled with energy and ready to be fired. Without a doubt, the rumbling was the best warning.

Tang Wulin flapped his wings. He landed on the ground with Long Yuxue and sighed in relief.

When they saw the great pair of golden wings behind him, many of the Blood God Army's soldiers displayed admiration on their faces.

Although those enlisted were outstanding talents, there was only a handful who were able to attain the ranks of a two-word battle armor master.

A gigantic light shield was erected before him. The threatening feeling he felt earlier immediately vanished. At this very moment, an extremely powerful greyish-black air flow surged out from the tunnel.

All the light shields shone at the same time. The dazzling lights merged together to form a giant light barrier which blocked the impact of the greyish-black light.

Amidst the greyish-black glow, something could be seen faintly, brandishing its claws. The terrifying force of the impact made the glow of the light shields burst forth with light.

Long Yuxue could only sigh in relief now. She looked up at Tang Wulin beside her and saw his grim-looking face. She patted her own chest. A moment later, she raised her soul rifle in her hands.

Although it was through a mini mecha, she felt a sense of security which came from Tang Wulin. This fellow truly lived up to the name of the Shrek Seven Monsters.

Naturally, Tang Wulin did not know what Long Yuxue was thinking of. He only felt the energy shockwave from the abyssal tide's impact.

The barrier formed by the energy shields sufficed for now. However, the energy tide's shockwave was very powerful. It seemed unlikely that the current barrier was capable of withstanding it.

As expected, a deafening alarm sounded after a short while.

"The abyssal tide's intensity is already at rank-3! The barrier can only last for five minutes max. All units retreat to the second line of defense, now! Meanwhile, report to combat command and request for backup. I'm afraid that the abyssal creatures are about to launch an all-out attack."

"Let's go." Long Yuxue pulled on Tang Wulin and charged into the tunnel.

Tang Wulin flapped his wings and followed closely behind.

"What does intensity rank-3 mean?" asked Tang Wulin as he followed Long Yuxue.

Long Yuxue's expression was grim. "Usually, the abyssal tide will be between ranks 1 and 2. At those intensities, our barrier is strong enough to keep them at bay. That's also the norm. Every few decades or so, the abyssal creatures will launch an all-out war where the abyssal tide will reach rank-3. A rank-3 abyssal tide will require large defensive equipment to hold it back. It also means that there'll be experts among the abyssal creatures that'll attack our defenses with all their might. At times like these, it's always the most difficult for us. I never thought that you'd be so unfortunate as to witness this event so early in your career. Even I haven't seen a rank-3 abyssal tide before. Get ready to fight. Every soldier will be mobilized for sure."

"Alright!" Tang Wulin did not ask further. Currently, the only thing that they could do was to continue fighting and wait for reinforcements.

They retreated to the second line of defense. Tang Wulin finally saw the large defensive machines. These soul tools were prepared well in advance. Rows of defensive formations were completed swiftly. Everyone moved in an orderly fashion and no one appeared flustered although the abyssal tide had reached rank-3.

Scores of soul tools, which Tang Wulin could not even recognize, were quickly assembled. The energy shockwave suddenly intensified. Tang Wulin saw a giant metal ball drop within the abyssal cavern behind them. The ball was more than three hundred meters in diameter. There were hundreds of light beams shooting out from below as they supported its weight. The metal ball itself was emanating an immense amount of energy. At the same time, huge strips of metal shot out of the ground from within the abyssal caverns, connecting themselves to the soul tools within.

"What's that?" Tang Wulin asked Long Yuxue, who was beside him.

Long Yuxue said, "That's the true core of our Blood God Army. It's known as Blood God's Heart. It's the product of immeasurable manpower and resources from the Federation as well as our own research efforts. There's only one Blood God's Heart in the entire Federation. It can convert a large amount of origin energy into soul power and channel it into our soul tools, forming an energy cycle. Do you know anything about integrated soul power batteries?"

Tang Wulin replied, "I've heard of them. They supply energy for large soul tools."

"Hmm. In a sense, the Blood God's Heart is similar. However, the Blood God's Heart utilizes the latest soul technology. It's a variation of a special metal developed by the Federation and its corresponding soul circuit. These metals are truly frightening. When they mutate, they'll erupt with an immense amount of energy. When they discovered this metal, the first thought the Federation had was to use it to make weapons. That's how the three godkiller-ranked fixed soul ammunition came to be. However, they were soon discontinued after they were made because the godkiller-ranked fixed soul ammunitions were too terrifying. Also, there wasn't much of the rare metal left. All of it had been used to make this Blood God's Heart so that it can supply us with a continuous and large amount of energy to guard this place."

Tang Wulin was shocked. Although he was not sure about the effects of the Blood God's Heart, he had personally witnessed the extremely powerful destructive energy of the godkiller-ranked fixed soul ammunitions! It was a catastrophe that could not even be withstood by a Limit Douluo with his four-word battle armor on. Shrek Academy and the Tang Sect headquarters had been destroyed under its attack. He never expected the Blood God Army to be in possession of such a powerful soul tool of the same rank.

"Hum." At this moment, a deep buzz sounded. The soldiers from the first line of defense had all retreated. A blue, light shield immediately took shape at the tunnel's opening, effectively sealing off its exit
