Soon, the huge metal door of the storage room slowly closed, separating the inside from the outside.

After seeing the closed door completely shut, the old man said hoarsely to Su Mo.

"Push me closer to the wall!"

"Okay!"

Su Mo pushed the old man closer to the metal wall.

The old man carefully observed the subtle patterns on the wall, his aged face revealing an excited expression.

"Heaven never disappoints those who have a mind to, I finally found it."

"Master, how are you sure it's here?"

Su Mo asked curiously.

"Because there are special marks left by my ancestors on it, which only the Blacklight Empire's ruler can understand. The entire fortress was built by the gods, that's right, but this secret room was designed by our people."

The old man explained hoarsely.

"Then how do we open it? The artificial intelligence, Eye of God, is already gone."

Su Mo asked with some concern.

"Don't worry, our Blacklight Empire ancestors naturally left a back door. As long as you have the purest Blacklight bloodline, you can open this secret room."

"Understood."

The corners of Su Mo's mouth twitched slightly. As expected, people are selfish.

"But my current physical state can't open this door."

The old man suddenly said hoarsely.

Su Mo was slightly stunned and asked in confusion.

"Why? It shouldn't take too much effort just for permission recognition, right?"

Su Mo was also a little confused about the situation.

"My body itself has undergone special modifications. Later, when I arrived in the Negative Universe, I was subjected to high-intensity negative energy pollution, and my gene sequence has long been mutated, becoming impure, so I can't open it at all."

"Then what do we do?"

"So this door can only be opened by you."

The old man raised his head and stared at Su Mo.

"Ah? Master, you're not joking with me, you can't open it, so how can I? Where do I get the authority?"

Su Mo was stunned when he heard this.

"You don't have it now, but that doesn't mean you won't have it later. Here, take this."

As he spoke, the old man tremblingly took out a bottle of black gene serum.

"This is?"

Su Mo was shocked to see the gene serum that the old man handed over, but he still reached out and took it.

"This is the type VI gene serum, Blackening Potion, made from the purest blood I extracted. After using it, you will obtain the complete Blacklight Empire bloodline. Not only will your strength greatly increase, but you will also automatically comprehend the Blackening talent."

The old man said while coughing. Of course, he didn't tell Su Mo that in order to prevent the Blacklight bloodline from dying out, he had already extracted his own authority, which was why he couldn't open the door.

"Master."

After hearing this, Su Mo was deeply moved.

"However, before injecting it, I have to make it clear about some risks."

The old man then said.

"Master, tell me."

Su Mo took a deep breath and said.

"What I want to tell you is the risk of injecting the type VI gene serum. If we followed my original plan, you should have injected the type VI gene serum smoothly, but when I saw that you actually used Divine Transformation, then everything is different."

The old man explained hoarsely.

"Uh, how is it different?"

Su Mo asked with a slight pause.

"If I'm not mistaken, you should have a Light Sequence gene in your body. Most likely, you injected the type VI gene serum, Divine Transformation Potion, and this sequence gene is mutually exclusive with the Blackening sequence. Therefore, if you inject the Blackening gene serum, there is a high probability that there will be three results."

"Which three results?"

"The first result is that light and darkness repel each other, the gene chain collapses, and you explode and die! The second result is that the injection is ineffective, and the third result is that the Blackening Potion will suppress the Light Sequence gene in your body. Moreover, I think the third result is the most likely, because the negative energy pollution on your body is very serious, which will greatly enhance the effect of the Blackening gene serum."

The old man said solemnly to Su Mo.

After listening to the old man's analysis, Su Mo couldn't help but take a breath of cold air.

The old man continued, "I've said everything I need to say. You weigh the risks and benefits yourself."

Su Mo took a few deep breaths, his heart was also very tangled. He was now at a crossroads, either giving up the injection and retaining the Light Sequence gene in his body.

Or inject the gene serum, take a gamble, bet that he can suppress the Light Sequence gene, and inherit the treasure.

The old man didn't urge Su Mo either, quietly waiting for him to make a decision.

A few minutes later, Su Mo's eyes became more and more firm, and he said to the old man.

"Master, I choose to inject!"

"Very good, before injecting, I still have some precautions to tell you."

After hearing Su Mo's words, a satisfied look appeared on the old man's aged face. He really didn't choose the wrong person.

"Master, tell me."

"Any type VI gene serum injection is very dangerous, and your situation makes the danger even more so. After you inject it, you will feel extreme pain, which is a normal reaction, and what you need to do is persevere and not faint. As long as you can make it through, your life will undergo earth-shattering changes."

The old man's eyes became more and more fanatical as he spoke.

Wasn't this his last gamble?

"Understood."

Su Mo nodded in response.

"You can inject it, I'll be watching you."

The old man said hoarsely.

Su Mo didn't hesitate at all. He directly removed the type VI armor covering his body, and skillfully injected the type VI gene serum into his body.

The moment Su Mo finished injecting, he felt his heart suddenly lock up, and his whole body's muscles began to twitch violently. Intense pain instantly swept through his brain.

He staggered and knelt down, but fortunately, he supported himself on the ground with one hand, preventing himself from falling down completely.

At this moment, Su Mo felt every nerve in his body being burned.

The severe pain made even breathing feel extremely painful.

The skin all over his body began to appear with dense cracks, like dry earth.

Su Mo's forehead bulged with veins, his eyes almost popping out, covered with bloodshot.

And this was just the beginning. With the fusion of the gene serum, the gene sequence in Su Mo's body began to mutate, reject, and conflict.

Then came the suffocating pain.

Even with Su Mo's strong will, he couldn't help but make a painful sound, and fell directly to the ground, struggling in pain.

"Hold on!"

The old man watched Su Mo struggle, and encouraged him in a hoarse and deep voice.

No one could help him with this hurdle.

The Creator Devourer looked at the extremely painful Su Mo, and said to the old man in a low voice.

"Old man, are you sure there's no problem?"

"Whether there's a problem depends on him, not me."

The old man replied hoarsely.

The Creator Devourer could only watch quietly.

Outside the storage room, Kartul and the others were all waiting at the door.

Everyone's expressions were very ugly, but Korete looked relaxed. He was silently timing it.

"Hmph, a waste of effort, and we can't even watch."

Atik complained very unconvinced.

"What can we do? He's just that favored."

Adomo echoed with displeasure.

"Enough, whatever decision the Lord makes is his business, we just need to obey."

Kartul replied in a deep voice.

"Kartul, are you so willing? You used to be the Lord's closest and most trusted."

Korete said at this time.

"None of your business."

Kartul replied without hesitation.
