Combat effectiveness is indeed the most important training and assessment indicator within the expedition, but on the whole, the space-time expedition has developed to the point where the execution of many missions does not rely entirely on the process of combat. In terms of daily training, this is not a normal unit.

Although the expedition also had the physical, shooting, and coordinated tactical training that any army has. But the main training content has shifted to purely technical. Not only are there various engineering and blasting professionals who practice how to dismantle or construct various equipment and buildings every day, but there are also many team members who mainly rely on eloquence to solve problems.

Each squadron has at least one actor who can skillfully disguise himself as someone from almost any background to engage in non-military contact with locals on the target plane. These were the people who brought back the first batch of individual equipment from the target plane.

In order to adapt to the complex and ever-changing environment of the heterogeneous plane, today's space-time expeditions have gradually become more like an espionage organization than a purely military organization. The team members have a variety of professional backgrounds and abilities.

Normally, such a team combination does not need to worry about survival in the Alien Plane. But this time, the new target plane they faced was in unprecedented danger, and in order to ensure that the two teams had enough chance to escape in the event of an accident, Shen Chao also prepared some special equipment for them.

Before leaving, Shen Chao personally led the team, escorted two suitcases to the training ground, and handed over two sets of special equipment to the two team leaders. When he came, Sister Xue and Master Chief were jointly planning the implementation plan for the core part of the plan, that is, the snatching plan for the future flagship.

Seeing that the two boxes marked with special logos were escorted to the scene by Shen Chao, Sister Xue immediately recognized what was sent and excitedly pulled the non-commissioned officer to surround her. "Is your magic scroll ready to use?" She asked.

"This is not a magic scroll, I told you......" Shen Chao helplessly held his forehead and sighed, but seeing Sister Xue's indifferent expression, he also knew that the other party would not change his words like this.

Even so. He still gave a positive answer, this new equipment, which Sister Xue called the magic scroll, has passed 137 rigorous quality tests, has undergone the test of various extreme environments, and is confirmed to be ready for use.

After blocking the training ground, Shen Chao officially opened the two special explosion-proof boxes, and solemnly handed over the two old-fashioned flashlight-sized barrel-shaped equipment contained in the boxes to Sister Xue and the non-commissioned officer.

Of course. He wasn't handing over any magical item. Although the expedition team has also sent people to explore a few planes with magical backgrounds very carefully, they have never studied any so-called magic in depth and obtained results, let alone rely on magic to make any core equipment.

This cylindrical device, nicknamed the magic scroll by Sister Xue, is actually the latest and most important technological achievement of the special engineering group under the space-time expedition, and in the research and development stage, this equipment has used many project codenames, including "TPS, emergency exit" and so on.

Like the "emergency exit" used when it was developed, the flashlight-shaped device is a device designed for escape. However, there are no lighting appliances or medicines in the cylinder. It looks like a metal tubular kettle. It also weighs almost 10 kilograms, making it very sturdy.

Unlike conventional survival supplies, this device has a very simple function. There is only one function, and that is to open a directional space-time door. The operating principle of the device is actually quite simple, and there is actually a space-time gate leading to the heterotopic base inside the entire device.

Inside the base of that heterogeneous plane is a set of special space-time gate stabilizing equipment, which can maintain a space-time gate with a diameter of about 25 mm, which is the size of a one-dollar coin. The heterotopic exit of this space-time door is locked inside the barrel-shaped device.

At the entrance of the other plane, there is a huge special device that concentrates a strong laser beam on the entrance of the space-time gate with a small diameter, maintaining the stable opening state of this tiny space-time gate, and at the exit of the device on this side, there is a special sensor that can be safely ejected out. Passing through the portal, it opens or closes the portal completely before the powerful laser beam on the opposite side destroys it.

The reason why Sister Xue jokingly called this device the magic scroll is another short name that originated from the early naming stages of this project. The aforementioned TPS, the name of this project is more straightforward, as an English abbreviation, it means "teleportation scroll" or "return to the city scroll"!

As the name suggests, the role of this device is actually similar to the "Returning to the City Scroll" in the magic background online game, which can create a direct passage back to his hometown once it is used. No matter how powerful the enemy is, anyone with the "Scroll of Returning to the City" will be able to escape from the pursuit by guò.

It is precisely because of this ability beyond common sense that Sister Xue jokingly calls it a magic scroll. Although the size of the equipment is not large, it is undoubtedly a strategic weapon, and imagine if it can be popularized. What would it be like for a space-time expedition to have such a device in hand?

It is conceivable that they will become unstoppable by then, and no strong enemy will be able to stop them from moving forward. Because everyone will partially have Shen Chao's ability to run immediately if he can't win. No matter how powerful the enemy is, he can't hurt a single person he can't reach.

Of course, it is precisely because of the strategic importance of this re-establishment that less than 10% of the people in the expedition are currently aware of the existence of the R&D project of this equipment, even within the expedition. Not to mention how many people know about the finished product.

In the past few months, the equipment has been tested for safety under the strict supervision of Castor and several other core members, and now the test is over, but the equipment itself cannot be immediately mass-produced.

Even if it can be mass-produced in the future, Shen Chao will not allow this kind of equipment to be manufactured too much, because his energy is limited, and now when the "Returning City Scroll" is still a store, it can also clearly remember every space-time gate in each device, and accurately control the opening state of these space-time gates, and can use his ability to control all space-time gates at any time to forcibly release these open space-time gates.

However, once this kind of equipment spreads, he will not be able to do such precise control, and no one can say that this new technology created based on his ability to travel through time and space will be used against him.

It is precisely because of this consideration that at the beginning of the design of this kind of equipment, its performance indicators were intervened by Shen Chao himself. Except for the default opening diameter of the space-time gate, which was much larger than he expected, the other design indicators were strictly implemented according to his requirements.

For example, this device actually has a service life. Each "Returning to the City Scroll" can only support 5 times to open or close the space-time gate, and then the built-in sensor will run out, and the space-time gate stabilizer at the other end will also automatically close the corresponding space-time gate stabilizer and block the corresponding channel.

And since both devices are located in the same military base on the same plane. It is also planned to set up a centralized space-time gate area in the future, so they can more easily arrange defenses, manage the opening and closing status of space-time gates, and maximize the use of limited resources.

Of course, these are all classified information that the upper echelons of the expedition sequence know, and the Master Chief has no way of knowing what the two metal cylinders in front of him are. Seeing that Sister Xue who was pulling him was so excited, he leaned in a little dazed and looked carefully at the two cylinders on the table.

"What is this?" The master sergeant, who saw this so-called escape device for the first time, asked after taking a "cylinder" handed over by Shen Chao, he had seen a lot of strange weapons and equipment and engineering equipment in the expedition team these days, but the cylinder in front of him still made him scratch his head.

As a guy who has only seen the space-time gate stabilizer a few times, and has not yet joined the expedition team, and does not know any insider information, he does not know the operation principle of the stabilizer, and it is difficult to imagine reducing the size of those building-sized devices to the size of a flashlight.

"It's a lifesaver for you, John. If you and Shepard encounter an enemy in the target plane or lead a team surrounded by a large number of hostile military forces, this device will help you open a directional space-time portal to the rear base, allowing you and your team to withdraw as quickly as possible, just as I did when I was in the team. Shen Chao briefly introduced the functions of this device.

After knowing that what he got in his hand was actually something similar to a death-free gold medal, the Master Chief finally understood why Sister Xue was so excited, and why Shen Chao would personally lead someone to escort these two small devices.

For veterans like them, the evacuation route is always the most important and error-prone part of the battle plan. Master Chief himself has experienced the pain of being cut off countless times during his long war career.

Many of the best warriors who were born and died with him were trapped on the battlefield by the Covenant for reasons like this, and many of them were Spartan warriors of the same class as him. And now, he actually has such an artifact in his hand that can make ordinary people evacuate the battlefield immediately.

While his confidence in the success of his new mission increased, the new equipment in his hands also made him feel a deeper concern about the future of UNSC. Although Shen Chao has promised that he will never take the initiative to provoke the UNSC after he leads the team back to the Halo Plane in the future, this does not mean that those bureaucrats within the UNSC will not be stupidly hostile to the Space-Time Council...... (To be continued......)

PS: First of all, thank you for the monthly ticket voted by "Li Hong, Jackyc, and the Rich Man II", if nothing else, the next chapter will reveal a new "copy plane", so please pay attention
