It is also an underground base, it is also a secret infiltration, it was a three-person companion before, but now it has become Qin Jun alone, although there is still cold rain left outside to respond, but when Qin Jun thinks of Zhang Daxing in his heart, it is inevitable that there will be a rare trace of memory and melancholy.

Zhang Daxing also has a younger brother and a younger sister in Yanjing, and Qin Jun was tired of running for his life before, and he has always forgotten to meet them and do his brotherly affection for his brother.

Qin Jun decided that after returning to Huaxia this time, the first thing he would do was to find Zhang Daxing's relatives.

"Boss?" Kevin's voice interrupted Qin Jun's thoughts.

"How?" Qin Jun came back to his senses.

"Why is there a sudden mention of the Greater East Asia Biological Research Center in the Wajima Country?" Kevin asked, puzzled.

"I don't know why, but I feel like this place is very similar to the place in the Japanese island country before. There are busy researchers, and there are human specimens soaked in liquid. Through the glass window, Qin Jun could see at a glance a row of two-meter-high cylindrical glassware inside, which contained all human corpses of different skin colors.

The glassware was filled with different colored liquids, and the corpses inside were suspended in the liquid, and these people were men and women, and each of them had different expressions, some with a calm face, some with a frightened face, and some with a painful face. But without exception, these people are naked, soaked in liquid, and their skin is covered with dense ducts.

"Human specimens? Is this the Indonesian military's secret research institute for chemical and biological weapons? Kevin couldn't help but gasp.

"I don't know if it's a secret research institute for biological and chemical weapons. However, it is certain that they are conducting live experiments against humans. In this way, it is easy to understand why the third floor is called a specimen storage room. Qin Jun's tone became cold, anyone who saw such a heartbroken scene would probably be like this.

"Human experiments on live subjects, which can be a vicious event that violates international conventions. Once exposed internationally, it is likely to be sanctioned by major powers. Indonesia secretly studies these things, and actually pulls the **** of the Japanese island country, aren't they afraid of the other party's leakage? Han Yu analyzed.

"The island countries are world leaders in the field of biotechnology. Aside from tourism, Indonesia does not seem to have any technology that can reach the international level. It's hard to say who is in charge of this matter. Kevin said.

"No matter who is in charge, at least these two forces have a share. Kevin, can you open the metal door combination lock here? Qin Jun glanced at the closed metal door.

"On the network system, I can't find the relevant information of the door lock, it should be that there is no connection to the network, in this case, I am powerless."

The metal door uses the old-fashioned code-based locking method, with a lockbox embedded in the wall next to it. The screws next to the box are covered with a thin layer of metal, leaving only the digital input key area exposed.

Combination locks should have been eliminated for a long time, and now the most mainstream is fingerprint recognition, iris recognition and portrait recognition systems. However, the more high-tech things are, the easier it is to be cracked by cyber hackers, and the old-fashioned combination locks are more secure.

Even if Kevin is incompetent, this kind of thing can't be difficult for Qin Jun. Under normal circumstances, Qin Jun likes to use the most direct method, but if he wants to open the lid of the box, it will inevitably cause damage to the appearance of the door lock, and he will definitely be discovered afterwards. However, he had already killed a few people in order to break in, so it didn't matter if he would be exposed afterwards.

Qin Jun took out a dagger and gently scraped the metal surface next to the password box bit by bit, Rao is his movements were as light as possible, and there would inevitably be a slight "squeak" screak between the metal cuts.

I don't know what material this metal box is made of, its hardness is even harder than steel, and the dagger is cut and rolled before it cuts out a small hole. And the two metal gates and the entire wall connected to them seem to be all made of this metal. It is estimated that standing at the door and bombarding it with rockets may not be able to shake it by half a point.

Luckily, the lockbox only had a thin metal surface, and it took five or six minutes to completely cut it open with two daggers, revealing the entire lockbox inside.

Disassemble the key panel of the lockbox, and underneath it is a jumble of intertwined wires. Normally, these wires will have a red and green distinction, but here they are uniform black wires. In this way, because there is no difference in color, it is impossible to distinguish which one is the main line and which is the auxiliary line.

It's up to you!

Qin Jun observed carefully for a while, and then quickly tore off the three black wires, peeling out the copper core wires and butting them together.

"Smack!" With a soft sound, a spark burst out on the circuit board, and the insulating skin on the wire burned due to the high temperature.

However, on the side of the metal door, there was a "dripping" sound.

The door opened.

"Is the door open?" Kevin's surprised voice rang out from the headset, "Boss, how did you do that?" ”

"Just kidding. Which country's agents are not experts in lockpicking, I think when I was in the NSA, I also opened a lot of various locks. What's more, the Special Ninth Bureau is a more powerful place than ordinary intelligence agencies. Hanyu snorted disapprerovantly.

"It's on!" Qin Jun exhaled lightly, this old-fashioned combination lock was similar to the principle of the various password inputs taught in the Special Ninth Bureau, so he used the simplest and crude method to cause a short circuit and cracked it as quickly as possible.

Walking to the door, Qin Jun pushed it inside with a little force, but the door didn't move at all. However, this smooth door does not have a doorknob on it, so it should not be pulled outward.

Qin Jun added a little more strength and pushed a few times, and finally felt the metal door move a little bit. It turned out that the door was not too heavy or too tight. It's that there's a lot of pressure inside. The whole air pressure pushes the door outward, causing it to force to push the door open.

The heavy metal door was carefully pushed open by Qin Jun little by little. Only then did Qin Jun realize that the door frame alone was nearly twenty centimeters thick, which showed how thick this door was.

Good guys, it's almost time to catch up with tank armor. Qin Jun was sure that even if he took a few C4 bombs to blast them, he might not be able to blow open such a thick, and at the same time very hard metal door.

Qin Jun grabbed a set of white all-encompassing coveralls, quickly put them on, carried a large travel bag full of weapons, pushed the metal door open a gap, and quickly got in.
