Soon, Ye Feng and Yi Yalan followed the stairs and arrived at the 30th floor.

If we simply look at the missile launch, the best position should be on the rooftop, but if the missile is placed on it, the virus will set up an observation station on the other commanding heights, which will be easily discovered.

So Ye Feng settled for the second best and chose the 30th floor here.

On the 30th floor, it is a rotating restaurant, and the place is very wide, just in line with Ye Feng's plan.

After coming here, Ye Feng first pulled up the curtains of the floor-to-ceiling windows around him, then cleared the table in the middle, and then took out the missile from the evolution box.

After taking it out, Ye Feng entered the coordinates of the virus's nest according to the operation process. Ye Feng did not need to operate the following matters. The launcher will automatically rotate according to the coordinates set by Ye Feng and adjust the missile launch angle.

If according to the original plan, Ye Feng only needs to press the launch button at this time, the missile will be launched and erased the entire virus's nest, and his mission will be completed.

However, the virus has established another research institute, so the plan has become much more complicated.

After Ye Feng debugged the missile, since the missile needed to be launched from the hall, Ye Feng installed an oscillator on the floor-to-ceiling glass in the center of the hall.

At that time, as long as Yiyalan starts the oscillator, the floor-to-ceiling window will be broken instantly and will not have any impact on the missile launch.

After arranging these, Ye Feng began to teach Yi Yalan what they do.

But in fact, there is no operation at all, because Ye Feng has already debugged these things, and Yiyalan only needs to press the switch to start directly.

After doing this, Ye Feng took out the evolution box and a pile of arms that had been prepared long ago.

This includes two lacerator rifles, 5,000 rounds, 200 grenades, 100 incendiary bombs, and some gasoline and other things.

These things are all used by Iyalan to save his life later.

Because when the missile is launched, it will definitely attract the attention of those patrolling viruses, and a large number of zombies will inevitably attack here.

If Yiyalan wants to withstand this huge corpse tide, it is impossible to withstand it with her superpowers alone. Not to mention anything else, she can't afford to consume the superpowers just by simply not being able to withstand it.

After taking out these things one by one, Ye Feng took out a metallic arm guard from the evolution box.

"This thing is Qianji Claw, this is the launch button, this is the sight, this is the drive button." Ye Feng took out this thing and put it on Yiyalan's right arm while telling the function buttons on it.

This Thousand Machine Claw is the key to Iyalan's escape.

After the missile is launched, the building will definitely be surrounded by a tide of corpses that are swarming in. It is unrealistic to escape and rush down directly. The function of this Thousand Machine Claw is a bit similar to that of a flying claw, but its function is more powerful.

Yiyalan was able to use this Thousand Machine Claw to shoot the built-in hook claw hair into the six-story apartment next door, and then he was able to use the special device of Thousand Machine Claw to glide over.

"After launching the missiles later, you will use these hot weapons to delay the situation. Remember to use the advantages of the terrain and weapons, keep a good distance from the corpse tide, and you cannot fight hard. You only need to delay for ten minutes at most, and I will definitely arrive at the apartment opposite to pick you up." Ye Feng reminded seriously.

"Yeah!" Yiyalan nodded obediently.

"The big yellow cat is also left for you, so you can be much safer." Ye Feng thought for a while, touched the big yellow cat's head, and carried her to Yi Yalan and said.

"No need, you need the help of the big yellow cat more than me. And it's only ten minutes, having these weapons is enough. Don't underestimate me. No matter what, I'm also a powerful psychic." Yiyalan said angrily with her hands on her waist.

Seeing Yiyalan like this, Ye Feng smiled and did not force himself. After reminding Yiyalan to be careful again, he left the building and headed towards the research institute.

It was already around 2:30 in the morning, and basically 90% of the viruses were resting, and the rest were just routine patrols.

Therefore, the difficulty of Ye Feng's infiltration will be greatly reduced at this time. At least after arriving at the research institute, installing time bombs will be easier.

Standing on the highest floor of the building, Yi Yalan was watching Ye Feng's running figure through the floor-to-ceiling window using an ultra-high-definition telescope.

At this time, Ye Feng was like a strong cheetah, running rapidly in the crisscrossing alleys. Every step he took, his body would move forward five or six meters.

One by one, the mutant zombies were cleverly blocked by Ye Feng's surrounding buildings and easily avoided the past. In just a few minutes, they crossed three streets.

Looking at this scene, Yi Yalan couldn't help but bit her red lips because Ye Feng ran too fast, at least five times more than she had just taken her.

This made Yiyalan feel that she was a drag, and it also strengthened her desire to become stronger.

But soon, Yiyalan's thoughts were interrupted because Ye Feng was running in an alley at this time. He originally rushed in to avoid three mutant zombies, but in another direction, a virus man happened to be coming towards Ye Feng.

Under such circumstances, Ye Feng was extremely difficult to hide because not far from Ye Feng, there was a virus-related person responsible for alerting the balcony of the mobile semi-open villa.

If Ye Feng climbed over the wall and left this alley at this time, without the obstruction of buildings, he would easily be discovered by the viral virus when he was in mid-air.

So, at this time, Ye Feng either faced the virus coming towards him, or retreated back to the same route, but in this way he would kill the three mutant zombies.

In Yiyalan's opinion, choosing to kill three mutant zombies will undoubtedly be easier.

Although this is risky of exposure, with Ye Feng's strength, he can hide his body after killing quickly, at least 80% of the chance of avoiding the danger of being discovered.

However, Iyalan's face changed slightly as soon as she measured the gains and losses in her mind.

Because Ye Feng didn't make the choice that was most beneficial to him, he slowed down and headed towards the virus man coming towards him.

"Why are he not afraid of being discovered?" Yiyalan couldn't help but exclaim. Even her hand holding the telescope was filled with fine sweat.
Chapter completed!
