Twenty days later.

The sky is gray and the wind is cold.

The water of the lake is as clear as jade, and the aquatic plants are swaying and stacked.

Xun Qiu, as usual, sat quietly on the grass by the lake, practicing perception.

During this period of time, he lived a quiet and comfortable life like a paradise. Under the morning star, he took three boys to practice perception, and in the afternoon, he made cards with Old Man Yuan, and after a wolf meal and tiger food, the night was his own mecha disassembly and assembly challenge time.

During this time, not only has his perception broken through the fifth level, but even his physique has improved a lot, after all, the challenge of disassembling and assembling is also extremely physically demanding.

And the three boys also benefited.

Ou Yuan's perception had actually broken through the third level, and Shi Xu and Cong Jiang had also practiced their perception to the second level under extremely superior conditions. And because of his suggestion, at this time, this mirror water lake has become a perception exercise base for Xinhancheng.

The beast that had never been seen in the depths of the water was apparently unaware that it had been affectionately called "The Silent Instructor" by these humans.

The number of A teachers who sit around the lake every day to exercise their perception is increasing day by day. But Vientiane is difficult to practice after all, and there are only a dozen or so people who can make use of this place.

A light breeze blew, and Xun Qiu opened his eyes.

He was already close to the lake at this time, and the trembling fluctuation of killing intent was nothing to him. Although I really want to go into the water to find out what this strange beast is. But this natural place for perceptual exercise, as long as it does not affect the safety of the people of Xinhancheng, he still hopes to keep it.

With a few clicks, Xingyue stood up, swept a step, and reached the side of the eagle closest to the shore of the lake.

"It's not working for me here. You continue to practice at your usual pace, and I'll go back first......"

After getting a response from a few people, Xun Qiu swept up one by one and galloped towards Xinhan City with a roar. The alien beast community along the way has been cleared up by the armor masters of Xinhan City, so there is no need to worry about disturbing the alien beasts. At full speed, in just half a minute, he returned to his residence in Xinhan City. The original [Beehive] has now changed its appearance.

After the dinner that day, Shi Lao found him and proposed the idea of helping him rebuild the [Beehive]:

"In addition to the energy card, we really don't have anything to get our hands on in Xinhancheng. Let's do what we can for you. ”

Xun Qiu naturally would not push away Shi Lao's kindness.

So, Ah Dong and Ah Li tried their best to coordinate, and together with a few mechanics in the city, they were stunned to transform Xun Qiu's original [Beehive] into an octagonal field barracks, which was almost the same in area, but the overall image looked much more beautiful. The built-in custom modules, after being picked up by several mechanics who have seen the world, appear to be more standardized.

This wild barracks renamed [Octagonal] is his new residence. In addition to the hall and the front and rear doors, there are six separate rooms.

Looking at this barracks with a rough appearance and a fine interior, Xun Qiu's heart warmed, jumped out of [Xingyue], and walked in.

With a pop, the mechanical door of the barracks closed automatically behind him.

Xun Qiu found a seat in the hall and began to check his reserves.

Because of Shi Lao's kindness, he now has hundreds of energy cards. The food reserve is enough for him to be embarrassment for half a year. And several mechs are also maintained to the best condition.

As long as the [Sand Sulfur Energy Card] is successfully completed, all his preparations will be over perfectly.

It's time to head back to the world of the Seven Seas.

I don't know how Lotte Yue did in their rookie game. Without my participation, would the results be ideal?

Xun Qiu smiled bitterly. Although his current level is already good among junior armor divisions, it is not easy to win in the rookie competition full of masters, right? Not to mention others, that Xu Chen alone is enough for him.

And his "father" Li Nuo was already a senior armor master twenty years ago. Whether it is Xu Chen, Li Nuo, or Xun Chang, they are all strong and prosperous at a young age. The world of the seven seas really has no shortage of geniuses. I relied on the support of Baixuan to get to this point, and my qualifications are really average.

With a light breath of turbidity, Xun Qiu took out the card maker and prepared to make the [Sand and Sulfur Energy Card].

Unlike regular storage cards, you can't use regular base cards to craft energy cards. If the card symbol belongs to software, then the base card belongs to hardware. Without a special base card, even if his card symbol encoding is completely correct, it will not work. This is where special card materials come in.

For example, the core material of an ordinary energy card is Secret Glass Ore. And to make sand and sulfur energy cards, in addition to the necessary secret glass, sand and sulfur are also essential.

To make the base card, of course, ordinary card makers will use the card slot that comes with the card maker to make it. However, the card maker uses physical grinding, which will inevitably cause a certain amount of material loss.

And he is different, he has Brown alchemy. Because Xinhancheng has a professional secret glass mine purification factory, he now has enough secret glass powder. As for the production of the base card, he can directly pass alchemy, without the need for a card maker.

As usual, he first went through several alchemy processes to make fluxes and coagulants for sand and sulfur. The sand-sulfur ore is then purified into liquid sand-sulfur by means of a sand-sulfur flux. The amount doesn't need to be much, even if it's a sand and sulfur energy card, the energy contained in it still comes from the secret glass, and the sand and sulfur is just a strengthener.

After that, he melted a portion of Cronin alloy into a liquid state and poured it into a slot above the card maker through a glass container, incorporating the precisely weighed secret glass powder and liquid sand and sulfur into it. Finally, add a drop of Cronin alloy coagulant. In an instant, a base card rich in secret glass and sand and sulfur was formed in the card slot above the card maker!

Next, it is the card making stage that he is familiar with. Although the Sand and Sulfur Energy Card has never been tried, most of its card makers are almost the same as ordinary energy cards, except that there is a special coding section for the Sand and Sulfur Activation Secret Glass. He has been helping under Old Man Yuan for many days, and the card making code of the energy card has reached the level of handy.

In the light curtain above the card maker, a string of card makers is like a piece of music full of life, jumping happily. It was only when he got into the most complex special coding segments that he slowed down significantly. It was a long form of coding that he had never used before, and he still needed to comprehend and digest it. The meaning of some of the special characters involved in it even Old Man Yuan didn't understand what he meant, so he could only draw a gourd without trying to understand it.

Although the perception has reached level five, making this sand and sulfur energy card still makes it sweat. Unlike ordinary energy card making, sand and sulfur energy cards are extremely sensitive to the use of card generators. Once he makes a mistake and calls the wrong card generator, if he wants to erase and rewrite, he needs to invest a lot of mental energy. This is also the reason why Perception must reach level 5 before you can make a Sand and Sulfur Energy Card. If the perception level is not up to standard, there will be a lot less chance of fault tolerance.

Fortunately, Xun Qiu would rather be a little slower than pursue speed, but still persevered.

It only took him about ten minutes to make an ordinary energy card, but it took him nearly half an hour to make a sand and sulfur energy card.

Xun Qiu smiled. He was already satisfied with the speed. After all, one sand and sulfur energy card is equivalent to twenty ordinary energy cards! Presumably, when Uncle Wupu collected sand and sulfur, he couldn't have guessed that it would be of great use one day, right?

And the sand and sulfur extracted from such a small piece of sand and sulfur ore is enough for him to make dozens of sand and sulfur energy cards!

Why don't you make a few for Shi Xu and them as parting gifts?

Xun Qiu, who had just been concentrating for a while, once again devoted himself to the production of the sand and sulfur energy card.

After making five sand and sulfur energy cards, Xun Qiu stopped under fatigue and hunger.

I didn't expect to be tired like this!

"Brother Xun! Time to eat! Outside the [Octagonal] door, Shi Xu's voice came. At this time, it was already noon, and Shi Xu and the others had already returned from Jingshui Lake.

"It's coming!" Xun Qiu leaned over, took a quick step, and opened the camp gate.

"Brother Xun...... What are you doing? Sweaty? Shi Xu saw Xun Qiu's hot sweat and exhausted appearance, and asked suspiciously.

"Say it at the dinner table!" Xun Qiu was so hungry that his chest was pressed against his back at this time, where did he have time to pay attention to Shi Xu? With a thud, he jumped out.

"Brother Xun......" Shi Xu caught up with Xun Qiu with a jump, and his feet moved as fast as two wind wheels, "Have you researched something new?" ”

Shi Xu always knew that Xun Qiu hid in the [Octagonal] every night, and Gu Zi was tinkering with something. Could it be that it has already borne fruit?

"Hmm!" Xun Qiu sat down at the big table in the cafeteria, beckoned Jiang and Yuanyuan, who had already sat down, and asked the three of them to come around, and then took out three sand and sulfur energy cards, and each person sent them one by one, "This is a new type of sand and sulfur energy card." It contains twenty times more energy than a normal energy card, so put it all away! ”

"Wow!" The three of them suddenly became starry-eyed, this is a dark golden energy card, "Thank you, Brother Xun!" ”

The three of them thanked each other.

"But it's a secret! Especially Old Man Yuan. Don't tell him. Otherwise, I would have been dragged and asked. Alas, Old Man Yuan, it is indeed extremely clingy. Xun Qiu remembered the scene when he met Old Man Yuan for the first time, and his heart trembled.

Once it comes to card-making related things, Old Man Yuan will never stop easily. If he knew that there was such a new type of energy card, he would not have to tie himself up in the house and interrogate him severely? Hehe.

"Understood!" Shi Xu's eyes reflected the stars, and his spirit was flying.

Master A knows that a mecha card can only be bound to one energy card at a time. Even if it's an energy matrix card, it's only ten energy cards. And the one Xun Qiu gave her actually has twenty times the energy reserves! This is really a great gift for a master!

The four of them gathered around and excitedly discussed today's perceptual cultivation. In particular, Ou Yuan is extremely enthusiastic in this regard. Because becoming a new generation of card makers in Xinhancheng has always been his heart's desire.

Just as they were eating and chatting with laughter, there was a bang in the training ground outside the city, and three scarred mechs descended. The mecha descended without slowing down, setting off a burst of yellow dust and dust!

After half a breath, a low, childish roar resounded throughout the city:

"Guys from Xinhancheng, I'm sorry!"

"Hurry up and hand over the energy cards, secret glass ore, and coins! If there is a violator, you will not be spared! ”
