At the end of the horizon there was a rumbling thunderous roar.

Most of the monsters that filled Midtown had already made their way to the pilgrimage route, and the devastated streets were rarely empty, and there were no more strange signs of wandering, except that the sky on this side was still gloomy and dark, and it was like being in hell without the light source.

Xia Chuwei sat on the edge of the fruit store and squinted into the distance.

The sound was the sky coming from the direction of the Cloud City store, and the blood-colored cracks in the sky at that location were getting brighter and brighter, painting the entire Midtown with a thick and indissolvable blood.

The survivors rested around the vehicle, and the food was distributed by the military, many of them looked gloomy, more than 700 people, and only 100 or so people ran out alive in the end, hiding in the bus, and there were not many injured, but this tragic escape, almost all of them had relatives and friends killed, and the future was bleak, and the current short-term tranquility could not make anyone really happy.

However, Xia Chuwei noticed a strange person.

It was a gifted person, who called himself Qiao Zheng, and kept shouting that he wanted to see Mr. Su, but he never succeeded, and even found Xia Chuwei here, but before Xia Chuwei could talk to the other party, Qiao Zheng was blocked by the bald boss trio as if he were some dangerous animal.

Seeing this scene, Xia Chuwei couldn't help but take a look at the bottomless darkness in the fruit supermarket.

Su Chen was there.

At this time, Su Chen was actually in a room on the second floor of this fruit store that had both bedroom and office functions, and he instructed not to let others disturb him, so he closed the door.

Under the strengthening, there is no need to turn on the light, with the help of the faint light source outside, Su Chen can also clearly see everything in this room, find a corner to sit down, Su Chen first took out the "crack" that was very large and relatively heavy, and tried to inject a little black energy into it first.

After such a long period of magic reform, Su Chen gradually figured out some rules and skills, and summed up his experience in practice.

Magic change items, he only needs to input some black energy into them first, and he can roughly estimate how many energy units are needed to complete the magic change.

At this moment, Su Chen was doing such a thing, and he quickly made an estimate.

To complete the transformation of this bazooka, at least more than twelve energy units are required, and its material itself is better than that of Mark 45, and the volume is not small, although the structure is not too complicated, but it is also a firearm, and the energy units required are naturally more.

Su Chen hesitated slightly, but put it aside first.

He doesn't have much energy, and now the monsters in Midtown seem to be flocking to the location of the Cloud City store again, and it has become difficult to hunt lone monsters, and the seventeen energy units in his hand should be used in key positions first.

For example, repairing Warframes.

The damage to the Pitch Black Armor is also unique, with the smallest units of the diamond disintegrating to ensure that the overall structure is not damaged, and as long as there are energy units, they can be reassembled into a complete Pitch Black Armor.

It's just that the repair process was a little longer than Su Chen imagined, and in a full hour, Su Chen used up thirteen energy units before he could restore his tattered battle suit to its original state. With the large consumption of energy units, Su Chen's state of excitement was also difficult to maintain, and he suddenly felt tired.

Previously, in order to quickly forge his armor, he had not rested for more than ten consecutive hours, and this battle made him even more physically and mentally exhausted.

No one is iron-clad, and Su Chen is no exception.

Su Chen hesitated, but decided to rest for half an hour first, he was lying on the bed in this room, closing his eyes and recuperating, he was not really asleep - the thunderous noise coming from the distance was too loud.

Fortunately, for his strengthened body, half an hour was enough to breathe a sigh of relief.

At this point, he still had four units of energy left in his hand.

Su Chen pondered for a moment and decided to try the magic power bank.

This is a plan he had a long time ago, that is, to build an "extracorporeal" energy storage device for himself, so that his body can only store thirty energy units, but with the energy storage device, this upper limit can be greatly increased, and he does not have to fall into the current dilemma of being dumbfounded.

According to the possibility of various previous magic changes, the last thing that may have an "energy storage" effect after the magic change is batteries and power banks.

When Su Chen was in the Cloud City store before, he actually tried to change the No. 5 battery once, but the result was a bit exaggerated, the No. 5 battery failed to become the energy unit storage device he expected, but instead became a small electromagnetic bomb-like thing-In the test, Su Chen was stunned to "blow up" a bunch of trumpet flashlights that Xia Chuwei had worked hard to collect at that time, but poor Xia Chuwei still didn't know that the culprit was actually Su Chen, and thought that those flashlights were damaged by unknown pollution.

However, at that time, Su Chen was under the cloud city store and had been rushing to make a suit, and the demand for energy storage devices was only in the theoretical stage, especially at that time, Su Chen didn't think it was very important at all.

But now the situation has changed, and after seeing the terrifying speed of his battle suit "eating energy units", Su Chen had to admit that the energy storage device must be made as soon as possible.

And Su Chen has a hunch that the monster is now fully shrinking and rushing to the "altar" of the Cloud City store, although it is temporarily safe, but in the face of the monsters' rituals, the military has not taken other actions for a long time, once their sacrifice goes smoothly or even succeeds, I am afraid that it will be a greater change and horror later, when he gets the energy unit, he must save time and energy to optimize the battle armor, the magic transformation "crack", grenades and so on. So, now is the only time to have time to try.

Thinking of this layer, Su Chen took out the power bank he had "stole" in the supermarket from his backpack.

In order to prepare for the future research of energy storage devices, Su Chen scavenged various batteries, power banks and even chargers in the supermarket. The good thing about the last days is that you don't have to pay for it when you go to the supermarket, for fear that others will loot it before you.

Su Chen first took out a small black power bank with a price tag of more than 100 8,000 milliamperes, took a deep breath, and slowly injected a unit of energy.

The reason why I chose this is mainly because of its small size, and the shell is also plastic, and when I grasp it in my hand, it looks like a girl's soft palm, and it only takes about one and a half energy units to transform it, which is what Su Chen, who is now a scarce energy unit, can afford.

This time, the magic transformation process is quite fast, in less than fifteen minutes, the power bank has been completed, the appearance of the palm-sized power bank has hardly changed, but it has become lighter, Su Chen took a deep breath, in view of the previous painful experience of the magic leather jacket, water cup, canvas bag, and battery, he was still a little nervous and apprehensive at this time, just like the mood when he was a child when he was a child.

Immediately after, Su Chen began to tentatively output a faint trace of energy into it.

Change is instant!
