System: Infinite Evolution into Qilin Bloodline

Wu Tianzhen thought about it and felt that Zhang Hao's words made sense. If he impulsively rescued these people now, the Wang family would definitely find out that they had entered the base.

Even if Zhang Hao is incredibly powerful, he won't be able to fight against so many opponents and will find it difficult to protect everyone.

The best course of action right now is, as Zhang Hao suggested, to first locate the base and bring all the Wang family members under control, and then release these teenagers.

So Zhang Hao led everyone to continue exploring the Wang family's secret base.

Along the way, they encountered many rooms with repetitive functions, and it wasn't until they reached the end of the tunnel that they arrived at the place where the Wang family was conducting their experiments.

Zhang Hao looked through the window in the door and saw several teenagers tied to chairs. Several staff members in protective suits were drawing black-haired snake venom into syringes and injecting it directly into the teenagers' nasal cavities.

The boy initially looked desperate and showed no reaction, letting the staff around him handle him.

But when the snake venom was injected into his nasal cavity, he screamed in agony, and his body began to tremble violently. He was unresponsive after only a few moments.

The staff members around him seemed used to this, simply shaking their heads and saying, "Failed again, next one!"

The boy's body on the chair was immediately removed, and then another boy was put on it to continue the experiment.

There were many such rooms along the way in the tunnel, but not many staff members.

Zhang Hao knew the importance of such a secret experimental base to the Wang family; it couldn't possibly be just these people existing there, there must be many security personnel somewhere.

Before taking action, the hiding place of those security personnel must be located.

Zhang Hao didn't let Wu Tianzhen see what was inside the room. Instead, he led everyone from the end of the tunnel into a mine.

Inside the mine, the dim light could barely illuminate a few steps ahead, and the air was filled with an indescribable chill and dampness, as if every inch of space contained an ancient and dangerous aura.

The six of them moved forward cautiously, their breathing unusually clear in the silence.

As they went deeper, everything inside the mine became clear.

This mine is different from other mines. Other mines are all excavated horizontally underground, but this mine is vertical, going straight up and down.

In the middle of the mine shaft, there is a support structure as tall as the shaft itself, extending all the way to the top.

Suddenly, a faint but rapid rustling sound broke the silence, like a ghost lurking in the night, silent yet omnipresent.

Zhang Hao immediately became alert, his eyes searching his surroundings, when suddenly a black flying gun appeared in his sight.

Black Flying Serpent is the Wang family's trump card. It is a symbiotic monster of humans and snakes, and with its amazing stealth ability and lightning speed, it is a powerful tool for spying.

The ancient city of Tongjing had snake mines, which were the raw materials for making black flying guns, so it is not surprising that black flying guns were found here.

"Watch out, something's getting close!"

Zhang Hao shouted a reminder.

Wu Tianzhen, Fatty, and the others looked around. It was pitch black and quiet all around. What was approaching?

Just as they were wondering what was going on, they saw Zhang Hao throw a punch at the air behind Wu Tianzhen.

With a loud bang, a strange figure suddenly appeared and fell to the ground.

"Holy crap, it's Black Flying Jet!"

Xie Xiaohua gasped in shock upon seeing the corpse on the ground.

That wasn't all. Zhang Hao moved with the agility of a cheetah, throwing punches at everyone's sides. In everyone's eyes, every punch from Zhang Hao hit the air with perfect precision.

But each time a muffled thud was heard, a black fly's corpse would appear out of thin air and fall to the ground.

Zhang Hao's punches whistled through the air, accompanied by dull thuds as black fighters were knocked to the ground one after another.

His speed and strength shocked everyone present.

"Why are there so many black flies?"

The fat man stared wide-eyed at the corpse on the ground in disbelief.

Huo Xiuxiu and Xie Xiaohua were also astonished. As members of the Nine Gates, they knew how powerful the Black Flying Spears were, and how precious each one was. But in this mine, Zhang Hao had killed more than a dozen Black Flying Spears in just a few seconds.

"Brother Zhang Hao, are there any more Black Flying Tigers around?"

The fat man wouldn't feel fear even when facing thousands of rice dumplings, but he was clearly terrified when facing the black flyer.

This kind of deadly monster lurks in the shadows, ready to attack you at any moment, but you can't see it or catch its movements, which is terrifying.

"This seems to be the lair of the Wang family's Black Flyers, but even the number of Wang family Black Flyers is not large. I have killed all the Black Flyers here for the time being."

In the past, when Black Flying Serpent appeared, Zhang Hao didn't even need to lift a finger; he could directly use his control over snakes to manipulate them for his own purposes.

However, he had already tried to control it when the first black flying drone appeared, but his control ability failed.

The Black Flyers here don't seem to be finished products, but rather semi-finished products. They are more ferocious and bloodthirsty than the finished Black Flyers, attacking anyone they see, but their abilities are much weaker than those of the finished Black Flyers.

Perhaps it was because they were defective that the operation failed.

"hiss……"

Just then, Zhang Hao heard a rustling sound.

He looked up and saw a peculiar black flying machine rapidly climbing down the support frame.

Surprisingly, this black flyer moved slowly and was extremely uncoordinated, making its presence easily noticeable to everyone.

"Why is there another black flyby!"

"How come this black fly has so many wounds? That shouldn't be the case!"

"He looks so old and frail, I think he's about to die!"

……

Zhang Hao and his companions kept their eyes fixed on the black flyer climbing down, to prevent him from suddenly attacking and injuring anyone.

The black fly stopped when it was about three or four meters away from Zhang Hao and the others.

"hiss……"

He stuck out his tongue like a snake, then withdrew it.

Then I saw him take an envelope out of his pocket and throw it down.

"hiss……"

Everyone was stunned by what they saw.

"What's going on? Is this black fly a traitor, sent to deliver messages to us?"

"Just pick up the envelope and take a look, and you'll know what's going on!"

As Wu Tianzhen spoke, she bent down to pick up the envelope from the ground.

"Wait, I'll do it!"

There was no way of knowing if the letter contained any poison or anything like that, so it would be risky for Wu Tianzhen to just take it directly.

Zhang Hao reached out and picked up the envelope, holding it in his hand.

There was no information on the envelope. He opened it and found two folded pieces of paper inside, one large and one small. The small one was about the size of an A4 sheet of paper, and the large one was about the size of a dining table.

The smaller ones were covered with densely packed small characters, while the larger ones had flat drawings on them.

He looked to the lower right corner and saw the words "Ancient Tongjing Restoration Project Map" written in large characters.
