When Lin Yi carried the heavy metal box back to the tent, Chen Yu was holding a piece of bread and swallowing it hard with cold water.
As soon as he saw Lin Yi, he immediately jumped up excitedly. As a result, he choked and beat his chest twice before he could breathe again.
"Brother Yi, you are back!"
Chen Yu's eyes were bright and he couldn't wait to share the good news, "Brother Yi, I understood what was mentioned on the radio these days, the second key node of the source energy cycle... I thought about it for a while on the way back, and suddenly I figured it out."
Lin Yi looked at Chen Yu, who was full of excitement, and showed an encouraging smile, "Very good, you have overcome the most difficult part. Keep up the good work. Getting started is just around the corner."
As he spoke, his heart moved slightly.
"During this period, the official explanation of <Basic Source Energy Guidance Technique> was given on the radio every day after dinner. It seems to be effective. It has only been a few days? Even a guy like Chen Yu, who has an out-of-touch temperament, has already mastered the second part."
This kind of lecture-style explanation is definitely much more efficient than the previous life where a single person or a small group relied on understanding the Information Flow engraved in the crystal. It seems that the analysis of teaching materials and the construction of the teaching system at the headquarters are progressing very quickly and effectively.
"With the progress of Chen Yu, combined with the Liu Yuan who came in a hurry..."
Lin Yi put the box in the corner and thought to himself, "Those with the best talents, such as the seedlings who were able to reach Star Core level or Stardust level in the previous life, Liu Yuan, it is estimated that in about a week, they will be able to completely understand Guidance Technique and successfully attract energy into the body."
"The talent is a little bit lower, but it can be considered a small talent, like Zhou Yuxuan, it will take more than half a month... but that kid is very thoughtful and strong. After being stimulated by me, maybe he can be faster in a few days."
"As for those with ordinary talents, I'm afraid it will take a month or two to find the way, but even so, it will be much faster than in the previous life..."
"In the end, it's hard to say those who really have no talent..."
With such a rough estimate, Lin Yi immediately felt a lot more relaxed.
According to this progress, when the first large-scale Abyssal Beast wave is bound to break out in more than two months, some people in each settlement should be able to successfully get started with source energy, and their physical fitness and mental reactions will be initially strengthened.
There may even be a very small number of Stardust level!
In this way, the overall resistance and survival probability will be much better than the situation in the previous life where the remaining thermal weapons can only be relied on to resist, and the number of casualties will inevitably be greatly reduced.
Just as I was thinking about it, the voice of Chen Yu came from the side.
"Brother Yi, I brought your lunch back for you."
Chen Yu stuffed the remaining bread into his mouth in twos and twos, and spoke vaguely.
He pointed to another piece of bread and a small bottle of water placed on the mat, "I have to go, the team will gather immediately, and we will continue to go out for search and rescue in the afternoon." He said, his eyes involuntarily glanced at the Silver-white Box Lin Yi brought back, his face full of curiosity and envy.
"I heard about it when I came back. Another helicopter has arrived to deliver good things to you, right?"
Chen Yu smacked his lips, and then sighed, "Oh, it's a pity that I don't have time to open my eyes. Captain Li said, while you have cleaned up all the powerful Abyssal Beast around, we must seize this golden time and save as many as we can."
Lin Yi nodded, he could understand the urgency. "Go ahead, pay attention to safety, act within your ability, retreat immediately and seek help if you encounter a situation that cannot be handled, and don't show off."
He patted Chen Yu on the shoulder, "Don't be impatient even if you don't understand the source energy for a while. Haste makes waste. The settlement can run only if everyone does their best in their position. Aren't your parents also busy in the logistics all day long without being seen."
"Understood, Brother Yi, don't worry!"
Chen Yu nodded heavily, without further delay, grabbed his equipment bag and rushed out of the tent.
The tent became quiet.
Lin Yi picked up the simple lunch, ate it slowly, and his eyes fell on the silver-white box.
After hastily finishing his lunch, he opened the box again, then stretched out his fingers and touched the crystals one by one.
The fourteen ordinary White Crystal in the upper and lower rows were just as he expected, all level 3 Source Energy Crystal.
But there's nothing wrong with it, it's considered hard currency.
In the middle row, there are four High-grade White Crystals on the left and right. The first one is ["Stronghold" Type II Disposable Personal Defense Force Field Shield Generator].
Injecting source energy into this thing in advance can instantly activate a 10,000-degree source energy shield, which is a good life-saving thing.
The second one is Shenfa <Flickering Light>.
Different from <Flowing Star Step> which focuses on small-scale tossing and continuous dodging, this footwork pursues the ultimate short-distance burst speed, rushing or retreating like teleportation, and is used to escape or pursue at critical moments.
The third one is Marksmanship <Immovable Mountain Spear>, a defensive Marksmanship.
"Why do they seem to be used to save lives...General Staff How afraid are you of my death..."
Lin Yi couldn't help but smile bitterly in his heart.
He continued to look carefully.
The fourth piece, fingering <Star-Condensing Finger>.
"Finally, it's not about defense and life-saving... it's just a fingering technique..."
Lin Yi thought for a moment, and he guessed that General Staff noticed his habit of frequently using his fingertips to clear out miscellaneous soldiers, so he chose the fingering technique.
After looking at four High-grade White Crystal, Lin Yi looked a little serious.
To be honest, the first four crystals are not of much use to him. They can only be regarded as icing on the cake. Of course it is better to have them, but it doesn't matter if they don't.
Whether he needs to change his tactics depends on whether there is anything he wants in the next three.
Lin Yi raised his hand and touched the first Gold-Veined Crystal.
<Soul Command>, a secret technique for training the control skills of Soul Power.
Lin Yi is a little disappointed. Even if these classics are not available, he has begun to prepare to "create his own".
So although this is a good thing, unfortunately, like the previous books, it is of little use to him. It can only be used to create more methods that he can use after learning it, and it is more convenient to create and teach others based on it.
The second Gold-Veined Crystal.
["Spring" Type II source energy recovery fluid]
"Eh... recovery fluid?"
Lin Yi felt happy, and then suddenly realized.
"Let me tell you... no wonder I said that the source energy should be enough to neutralize the nest. General Staff believed it without any proof. It turns out that there is this thing in the inventory... a bottle of Type II recovery fluid is enough to restore half of the source energy of Stardust level level 1. It is enough for anything."
The recovery liquid is different from the popular Source Energy Crystal. This is a medicine that can quickly restore the consumed source energy. It is extremely precious and can be regarded as a life-saving item.
After taking the Source Energy Restoration Liquid, Lin Yi felt a lot more relaxed instantly.
With the recovery fluid, at least he doesn't have to be just a Source Energy Neutralization tool during the war.
Although this is not what he wants most, it is not bad. It can also help him to intervene in the battlefield while performing Source Energy Neutralization.
Then, he put his fingers towards the last one, Green Crystal, ready to see if there was any surprise.
"There really is..."
["Flowing Shadow" portable single aircraft].
Lin Yi I had already prepared myself mentally for some fingering stunts and the like, but I didn't expect that there was an unexpected surprise.
"Flowing Shadow Little Flying Ball... I really miss it."
Lin Yi sighed in his heart.
This so-called Flowing Shadow single-person aircraft Lin Yi had been used in the previous life, and it was used for a long time before being promoted to Star Core level.
This is a small spherical aircraft. Although it has high energy consumption, slow speed and low load, it at least gives the user valuable air mobility capabilities. Whether it is reconnaissance, assault or escape, it will bring huge tactical advantages. Moreover, the key is that this thing can also be miniaturized.
Therefore, Flowing Shadow Little Flying Ball has always been a hot commodity.
"Little Flying Ball Although it is an unexpected surprise, it is not very useful for defensive operations at a fixed location... um... fingering... source energy recovery liquid..."
Lin Yi quickly put aside the matter of Little Flying Ball. His eyes flashed, and he began to quickly integrate these new abilities in his mind, deducing and optimizing the established tactics.
