Du Yuqi looked up and found that the one who was cursing like a hair dryer was Dr. Marka in a white coat. His eyes were red and his face was tired. No wonder he asked someone to make him strong coffee.

The one who was scolded by him and didn't even dare to utter a sound was a cowardly young man who looked like a punching bag. His face turned blue and red, and he seemed to want to explain but didn't dare to speak.

After a while, Dr. Malka finally got tired of scolding and roared:

"Why are you still standing here? I want strong black coffee, right now, immediately! If I don't see steaming hot black coffee within ten minutes, you're dead! I'll throw your head into the contaminated incubator to teach it a lesson!!"

After yelling, he slammed the door of the office next door and locked himself in the office again.

The young man Ren Ze stood there blankly, his shoulders shaking, looking as if he was about to cry in the next second. Du Yuqi had an idea and walked over from his laboratory, patted him on the shoulder and said:

"Hey man, there's nothing impossible in this world! Don't take it too seriously."

The thin young man Renze turned around, said with a bitter face and red eyes:

"But, but there is only hot milk, and what I just sent in was the last cup. It has been seventeen days since the ration was replenished. Where can I find black coffee?"

Du Yuqi reacted very quickly. After a moment of hesitation, he immediately smiled and said:

"I thought it was nothing. Only the doctor likes this. But I want to spit it out as soon as I smell the coffee. I would rather drink water than this stuff. I just happen to have some here. I might as well give it to you so that you can pass this test?"

Ren Ze immediately said in surprise:

"Really?"

Du Yuqi said:

"Yes, yes, but this black coffee is in my friend's bag, and now he asked me to help him get the three-phase instrument..."

Ren Ze immediately said:

"I'll get this for you! The unused three-phase instrument is in the warehouse, it's quite far to walk!"

Du Yuqi said:

"Well, bring the Triphaser over for me. I'll go make some coffee and send it to the doctor, so he won't get anxious if he waits too long."

Ren Ze seemed to have suffered a psychological trauma from being scolded by Dr. Marka. It was great that Du Yuqi was willing to help him bring coffee. He immediately nodded excitedly, and then swiped the door of the core laboratory to open state to facilitate Du Yuqi's entry and exit.

Du Yuqi waited until Ren Ze left excitedly, then went to get a cup. He didn't have strong black coffee, but there were still a few bags of Nestle instant coffee in the dimensional ring. He made a bag at random and handed it to the doctor, then walked to the outside of Dr. Marka's private office and rang the doorbell.

Dr. Malka's hoarse voice rang out after a while:

"Why are you here if you're not going to inspect the lines?"

Du Yuqi realized that Dr. Malka could see him, so he raised the cup so that he could see the hot coffee inside:

"Jenze helped me get the Triphaser. Please let me bring coffee to you, Doctor."

Soon, the door of Dr. Malka's private office opened, and Du Yuqi walked in with a cup of coffee, smiling. Dr. Malka took the coffee with one hand, and waved his other hand at Du Yuqi casually as if to shoo away a fly, and said impatiently:

"Go do your work now, and don't let your stench pollute my office."

Hearing this, Du Yuqi did not take it as an offense, but smiled and said:

"Actually, I came here this time because I want to ask you for help with something, Doctor?"

Dr. Malka said angrily:

"Get lost! How can I help a lowly fellow like you? Get out of here right now, or I'll let you know what it feels like to be electrocuted by 380 volts of electricity."

Du Yuqi sighed, then shrugged and said:

"What a pity, Mr. Doctor, even if you don't want to help me, I can't do it."

Dr. Malka was furious and his first reaction was to call the guards, but when he looked up, he saw a fist rapidly growing larger in front of his eyes, and then everything went black and he knew nothing.

A few minutes later, Du Yuqi bowed and backed out of the office, rubbing her stomach carefully. She looked as if she had been kicked hard. At this time, Ren Ze said nervously beside her:

"How about it?"

After all, for him, if Du Yuqi didn't do this job well, wouldn't it be him who would be responsible in the end?

Du Yuqi sighed and frowned, trying to endure the pain and said:

"I brought the coffee in, but the doctor got furious and said I was disturbing his work. I had a hard time getting away... and now the doctor looks like he's fallen asleep on the table. Do you want to go take a look?"

Ren Ze felt relieved immediately after hearing Du Yuqi's words, and finally waved his hands repeatedly and said:

"No, no, just sleep. It's rare for the doctor to get some sleep. If someone disturbs him at this time, the consequences will be very, very tragic."

After hearing Ren Ze's words, Du Yuqi smiled slightly. He had expected his answer, so he patted him on the shoulder and left.

…

A moment later, the protagonist and Jim returned to the place where they first entered and met their companions again.

By this time Lin had returned, and he had obtained a lot of useful information. Not only did he figure out the road ahead, but he also told everyone that the Imperial Army's offensive was unprecedentedly swift and fierce. They had fought off multiple attacks by the crew members on the ship in succession, and had expanded the area they occupied, making Carloka anxious and exhausted. There was even a raging fire in that area on the Iron Fortress. If the war fortress had not borrowed the "watertight compartment" model of the ship in the early stages of its design, they might have had to consider an emergency landing at this time.

After Du Yuqi communicated with Duize for a while, he knew that he had a time bomb of incredible power, so he asked Duize and Jim to re-enter the production area and place it in a vital place. Previously, Du Yuqi had directly dealt a heavy hand to Dr. Marka, and also searched away his authority card.

Dr. Marka's identity has been introduced before. Under normal circumstances, even the captain has to listen to him. After Kamoka's rebellion, no one cared to cancel his privileges. The authority on this guy's card is quite amazing. Duize relied on this advantage to place a time bomb in the vital area where the crystal source liquid was stored, and then he took the time to slip away.

Du Yuqi and his men did not delay any longer. They changed into the clothes that Lin had found and rushed forward quickly along the passage! They had already discussed everything before setting off. They rushed forward quickly, playing with the time difference. It would be best if they could capture the thief before the other party could react.

There are two reasons for making such a decision. The first is that 80% of the attention of Kamaka and others should be focused on the Imperial Army, which poses the greatest threat. Therefore, the attack by this group of people will be covert and sudden.

The second point is that they also carry the fangs of the ghost wolf Daka with them. With this thing, they can go straight to the dragon's lair without worrying about the tricks set up by Kamoka and others to evade the enemy.

In this situation, the group of people relied on Dr. Marka's authority card to pass three levels and directly entered the core area of ​​the Iron Fortress. If the area is divided according to function, it should be called the command area.

Needless to say, the command area was also heavily guarded at this time. Once you entered, you would see a long passage with steel walls on both sides and an alloy steel door at the end. There was a camera on the door looking over coldly.

If you want to enter the command area, you have to pass through this fifty-meter-long passage and then swipe the card at the end to enter. If it were on flat ground, this mere fifty-meter distance could be reached in a flash, but in this environment, it seems particularly long.

At the same time, there are dark holes next to the alloy steel door, some large and some small. It would be fine if you could see what kind of weapons are inside, but if they are hidden behind, it makes people feel a strong unknown threat, which immediately makes people feel creepy.

Just two or three seconds after entering this passage, Du Yuqi's face immediately changed and he said in a deep voice:

"retreat!"

When he said the word "retreat", he found that there was also a sound of "retreat" coming from the side, and it sounded like an echo. Du Yuqi took a look and found that it was Duize who said the word at the same time!

At this time, Du Yuqi had no time to ask what was going on. He immediately turned around with a gloomy face and aimed his sword at the slowly closing alloy door behind him! A raging flame suddenly burned on Kulan's Flame Shadow Sword, and it was obvious that he had used all his strength.

Duize also turned around and fired, several armor-piercing bullets blasted over, but Du Yuqi's heavy sword and Duize's bullets were intercepted half a meter away from the alloy door. After a series of explosions, several cracks suddenly appeared in the air! The two people's faces changed immediately. It turned out that after confirming that they had entered, the people from the ZERO organization quietly lowered a transparent glass wall to block the retreat! !

The fact that they were so impatient was enough to show that they had already determined that Du Yuqi and the others were spies! !

Seeing that Du Yuqi and others had already taken action, alarms rang all around. The walls of the steel corridor next to them shone red, and a large number of well-camouflaged covers were immediately opened, revealing black holes emitting a dangerous aura. Then a large amount of poison gas gushed out, refracting laser beams and micro missiles. At the same time, a large number of heavy firepower weapons slowly revealed their hideous appearances.

It turns out that this is an absolute death trap!!
