After the microwave laser beam bombarded the ground of the Music Fountain Square several times in a row, all kinds of pipelines that were originally buried deep under the Music Fountain Square were blasted into pieces, leaving a huge pit on the ground.

When the depth of the bombardment reached twenty meters, the original one was buried deep in the ground, and a somewhat rusty white metal shell revealed its original face from the soil.

"Found it!"

Han Feng saw the rusty white metal shell buried deep in the ground, and a gleam flashed in his eyes.

The man-made building that can be buried in such a deep soil is probably the only one that has the Orange Prefecture Jiangxin Island Secret Research Institute.

When Han Feng discovered the white metal shell buried in the ground, he immediately stopped emitting a microwave laser beam.

He didn't know if the shell used to protect the secret research institute was thick enough, and it would be embarrassing if this protective shell could be easily penetrated by the microwave laser beam.

Therefore, for this metal shell, Han Feng decided to solve it through refined operation.

He pushed open the door and stepped out of the Unimog RV, reaching the white metal casing buried deep in the ground, and raised the Darkmoon Knife.

Wrist movement.

The Darkmoon knife slashed straight at the white metal shell.

"When ——!"

With a crisp sound, the serrated blade of the Darkmoon Long Knife slashed straight into the white metal shell.

"I didn't expect the protective shell of the underground secret research institute to be really thick."

A slash from the Dark Moon Long Knife cut through a metal protective shell about fifty centimeters thick, but with this slash alone, it was not enough to completely split the protective shell used to protect the underground secret research institute.

"Huh——! Open it for me! ”

Seeing this, Han Feng took a deep breath, a puff of white smoke erupted from his mouth, and then his arms exerted force again, changing from slashing to stabbing, and the Dark Moon Long Knife was like a sharp spear, directly stabbing into the white metal protective shell.

"There it is!"

When a turbid and foul-smelling air gushed out from inside the protective shell, Han Feng finally breathed a sigh of relief.

As soon as the first cut was cut, the protective shell could no longer stop his progress.

"Roaring ——!"

Just as Han Feng used the Dark Moon Long Knife to cut through the metal protective shell, a roar suddenly came from above his head.

It turned out that Da Tangerine took Cui Yuanyan to visit all the large survivor organizations in Orange City, and after returning to the parking lot, he found that Han Feng and Wang Yingyu were gone, and he immediately followed the breath of the two and rushed to the sky above Jiangxin Island in Orange Prefecture.

When the figure of the big orange appeared above Jiangxin Island in Orange State, Wang Yingyu also walked out of the Unimog RV.

However, Han Feng looked at the gap that he cut out and was only enough for one person to pass through, and then looked at the unusually large size of Big Orange, and still commanded Wang Yingyu who walked out of the RV:

"You and Big Orange stay on the ground, and I'll go down there and find out for myself."

"Okay! Then you should be more careful. ”

Wang Yingyu also knew that this secret laboratory was only a part of the Spark Project, and the things contained in it should not be enough to threaten Han Feng, so she didn't make any moves, and directly nodded and agreed to Han Feng's request.

And she walked to Big Orange's side and naturally began to help Big Orange comb his hair.

When a bright light shot to the ground from the gap in the secret laboratory on Jiangxin Island in Orange State, a bat-like figure flashed through the air.

This figure is naturally Han Feng who entered the secret laboratory of Jiangxin Island in Orange Prefecture from the gap in the protective cover.

"It smells so bad!"

After Han Feng entered the secret laboratory on Jiangxin Island in Orange State, he couldn't help but cover his nose and mouth.

Originally, the secret laboratory of Jiangxin Island in Orange Prefecture was originally buried deep underground, and the air inside it was originally operated by the generator brought in the institute to drive the air circulation device.

After the outbreak of the apocalyptic virus, the generator ran automatically for a certain period of time, and no one replenished it for a long time, so the generator naturally stopped operating.

Once the generator stopped working, all the tools that needed energy to operate in the entire secret research institute stopped working at the first time, including the most critical life support system in the entire secret research institute.

When the life support system is stopped, the built-in air circulation system will naturally stop working.

Han Feng only felt a trace of a stench when he entered the secret research institute of Jiangxin Island in Orange State at this time, which had already benefited from his strong strength as a gold-level evolutionary.

The powerful strength of the gold-level evolutionary helped him block many deadly bacteria and viruses floating in the air.

If an ordinary person comes to the secret research institute at this time, then that person, the moment he enters the secret research institute, he will be directly choked by various harmful gases floating in the air, and even die on the spot.

"Huh! What about the people in the secret institute? ”

However, from the gap in the protective cover, Han Feng, who entered the secret research institute of Jiangxin Island in Orange Prefecture, found a very strange place, although after he entered the secret research institute, he found several rows of various research instruments.

For example, a large biomaterial analyzer, and several huge metal pressure tanks one person high, and a whole row of computers were also in front of him.

But he just hadn't seen a single corpse, not even a human-converted zombie.

That's a little weird.

Unless there is no one in the entire Orange Prefecture Jiangxin Island Secret Research Institute.

In the presence of people, a large number of people will inevitably turn into zombies and attack their colleagues around them.

But now the situation in the entire Jiangxin Island of Orange State, the secret research institute is too weird.

The experimental instruments and equipment were all intact and placed where they should have been.

It doesn't look like it's been hit in any way, which is enough to make it doubtful.

When Han Feng found that in the entire secret laboratory, all kinds of instruments were placed in their original positions, he also took the initiative to slow down.

The light from the strong flashlight illuminated a tightly closed door in front of Han Feng.

And after Han Feng saw the nameplate hanging on this door, a look of excitement flashed on his face.

"Experimental Center!"

Looking at this nameplate, Han Feng also understood that he must have found the main owner.

Without even thinking about it, he immediately used the Dark Moon Long Knife to pry open the door of the 'Experimental Center' that had been sealed.

However, he cautiously walked into the 'experimental hall', and the bright flashlight in his hand had just illuminated the surrounding scene, and he let out an exclamation:

"What is this? How can it be! ”
