Selena was awakened by the clear cry of the snowbird.

She opened her eyes and saw golden sunlight shining into the bedroom from the narrow window, forming a golden light curtain in the room, which was very beautiful.

Subconsciously, he tried to wake Rosen up, but came up empty-handed. Then he recalled what happened last night.

At ten o'clock last night, forest spirits invaded. After more than an hour of fear, they said that the forest spirits had been completely wiped out.

Then she yawned and was asked by Rosen to go back to the house to rest.

She wanted to insist, but he said that girls who stay up late age faster, and told her to go to bed first and he would follow her after he finished the chores at hand. Anyway, after hearing all these soft and hard reasons, and she was really sleepy, she went back to the bedroom in a daze.

Now it seemed that her husband had been busy all night.

She was grateful for her husband's care, but worried about his health, so she quickly got up, washed up, took her breakfast, and went straight to the underground alchemy room.

The entrance to the alchemy room was covered by a magical barrier, but this certainly wouldn't stop Selena, just like the barrier that Selena had set up, which left a secret code for Rosen to pass through.

As soon as she entered the basement, Selena found that it had changed a lot compared to last night.

There are many more strange-looking craftsman puppets.

Some have arms that can rotate and move, some are flat plates that move steadily on the ground, and some are things that have never been seen before.

These puppets are busy all the time.

Transport materials, carve runes, operate alchemical equipment, and more.

Among these artisan puppets, a humanoid skeleton has been completed for more than half and is taking shape at a rather incredible speed.

But as a mage, Selena could see at a glance that these fancy artisan puppets were not the key.

The most crucial thing is a corner of the room, a huge rectangular block with a side length of more than 4 meters and a height of 3 meters.

The outer edge of the rectangle was engraved with strange inscriptions that she had never seen before. They looked similar to lightning inscriptions, but had many unique changes.

Her husband was standing next to this strange rectangle, with one arm around his chest and the other resting his chin, deep in thought.

After hearing the noise, he turned around and a gentle smile appeared on his face that Selena felt very familiar with.

"Good morning, my beautiful lady."

His tone was cheerful and he looked very good, not like he had stayed up late at all.

Serena was relieved and handed over the breakfast: "How are the invading forest elves?"

"There were 200 of them. We killed about 180 on the spot and captured more than 20 alive. Not a single one escaped."

"What about our fighters?"

"Five or six were injured, but no one was killed."

"Oh, that's great."

Selena was very happy, but also worried: "Will such night raids happen frequently in the future?"

Rosen shook his head: "No, this is likely to be the last battle. If you are unlucky, you can fight one more battle. But there will never be a third battle."

Seeing Selena's confused expression, he explained a little more.

"The one we defeated last night was a group of the most capable Forest Elf warbands. Their status in the rebel army is no less than that of the Flame Warband to us."

"If we defeat them, we will establish our authority."

"Oh, I see."

Selena felt relieved and turned to look at the rectangular block: "Is this the lightning container you mentioned? I think it should be called a lightning house."

Rosen smiled: "Then let's call it the Lightning House."

Selena walked around the Lightning House and said, "I see many light-guiding runes. Are they guiding sunlight from outside?"

"right."

"What is the conversion efficiency of light power into lightning?"

Rosen narrowed his eyes and smiled: "About 10 parts of sunlight can be converted into 6 parts of lightning."

A photoelectric conversion efficiency of 60% would make a lot of scientists jump up and down on Earth, but in this alien world, there is still a lot of room for improvement.

Based on Rosen's current research, the limit should be 91.5%.

Selena's eyes lit up when she heard this: "That's great."

Then he asked: "How long will it take to create 50 combat puppets?"

"If we work together, and with the help of these craftsman puppets, we can get it done in seven days."

Rosen explained while eating breakfast.

After they finished eating, he clapped his hands and said, "Let's get started, ma'am. The next seven days will be our busiest seven days. After that, there won't be much hard work."

Selena was startled: "You are the lord, how can you stay in the laboratory all the time?"

The lord is a person who attracts everyone's attention. There are so many eyes watching him. If he has diarrhea, the news will spread all over the city. What's more, he has not appeared for a long time? Rosen clapped his hands: "Wake up."

In the corner of the room, a curtain was lifted and a person walked out.

This person looks exactly like Rosen, and is puppet No. 2.

This was the first time Selena saw Puppet No. 2, and she immediately walked over to examine it carefully.

A few minutes later, she commented: "Very similar to you, but there is still a vague sense of stiffness."

Rosen smiled: "Madam, you are a master of magic and you are very familiar with me, so you can easily find the difference, but others can't see it."

"That's true. But how did he cast the spell? Is it the common method in the Standard Spell Puppet?"

"That's right, it's using the crystal lattice in the body to cast spells."

"I installed four types of crystals: mind, wind, force, and arcane. A total of 58."

That is to say, this puppet can release a total of 58 low-level spells.

This is cumbersome, and subsequent recharging is also very troublesome, and an obvious ultimate solution is to use the 'Pure Mana Lattice'.

Whatever spell energy you need, just use pure mana to convert it in real time.

Sadly, this is just a dream.

This is because there is an iron law of magic that has defeated countless geniuses, called the 'Supreme Law of Life'.

That is, 'Pure mana cannot be stored in any non-living container other than the soul.'

So far, there have been no exceptions.

Back to the topic.

Serena was filled with emotion when she heard this: "It's really hard for you to fit 58 low-level crystals into such a small body."

"It's a bit troublesome indeed."

Rosen controlled Puppet No. 2 and walked towards the laboratory exit.

"Next, I can control him to handle government affairs remotely while he is busy in the laboratory. After all, most of the time, the lord just needs to sit in the study and take a nap."

Selena praised: "That's a good idea."

She also calmed down and focused on helping Rosen continue to improve the magic laboratory.

The view returns to puppet No. 2.

After walking out of the underground laboratory, Rosen immediately took 5 bottles of Dragon's Blessing and went to Wei Ge's potion room.

After the battle last night, the rebels will either be too scared to come, or if they do come, they will definitely be very well prepared and have a large number of people. It will most likely be a decisive battle!

As a lord, of course, he does not want to see the worst case scenario, and he will try his best to avoid it, but he must prepare for the worst case scenario.

We soon arrived at the destination.

In addition, she also recruited five young apprentices with a foundation in magic and a clean background on the island as assistants.

When Rosen arrived, she was researching the improved steel potion according to the task originally assigned by Rosen.

After seeing Rosen, she turned her head and her eyes quickly fell on the pottery jar.

After taking a closer look, she immediately handed the work at hand to a young apprentice beside her.

"Is this the dragon's blessing from the forest spirit wizard master?"

Rosen handed over the potion: "It seems that you already know a lot."

"This potion is very strong. After drinking it, you will become extremely powerful and your body will be as strong as steel. I haven't found a spell to remove the effect yet."

Wei Ge's eyes suddenly showed a light of great interest: "Hmm~~ Even you can't dispel it? It seems that this witch medicine is really quite useful."

In her opinion, although Rosen's magical powers were not high, he was extremely knowledgeable.

She opened the medicine jar, sniffed it gently, and then tested various potion reagents one by one.

Finally, he closed his eyes and thought for a while, and concluded: "This is not the witch medicine of the primitive tribe, but the medicine refining method of the ancient Set Kingdom."

Rosen's eyes flickered when he heard this: "The Kingdom of Set on the giant island of Veran?"

He had always been wary of the forest spirit's master of sorcery because the other party was a wild man with unknown origins.

But if there is evidence to support it, the threat level from the other party will instantly drop by an order of magnitude.

As long as you look up relevant information about the ancient Set Kingdom, you can get a feel for the vein of its power.

And this information is in Lai Fu’s database.

'I need to take some time to look at it carefully.'

At this time, Wei Ge's voice came again.

"Yes, it is the ancient kingdom destroyed by Saint Weilan. According to the research of Master Samira, a famous naturalist in our country, when the kingdom was destroyed, some scholars of the Set Kingdom fled on a boat with the magic materials."

"It now appears that some scholars have fled to the White Sturgeon Island."

Rosen was delighted: "This is very good news."

This is the benefit of cooperation and communication. You can use other people's knowledge to fill your own knowledge blind spots.

Wei Ge carefully poured out a little more potion, stirred it with some new reagent potion and tested it, and came to the second conclusion.

"There is a very powerful ingredient in the potion, a kind of blood. But I don't know what animal's blood it is yet, so I need time to explore."

Rosen immediately left the remaining four bottles of medicine: "These are all for you to use as test samples."

Wei Ge nodded happily and gave Rosen another idea.

"In fact, the method of refining this potion is very crude, and it greatly wastes the power of the blood."

"I know a potion formula that can be used with ordinary materials to create a potion with similar effects or even stronger."

"This is Levinder's secret medicine, called 'Heroic Hymn'."

This is also a very good solution.

Rosen immediately asked, "What is the output?"

"Based on the current situation, we can fill about 50 bottles a day at about one liter."

“Are there any side effects?”

"After drinking it once, the effect of the drug lasts for an hour, but you will be weak for ten days, so you can only use it to fight with all your strength."

"Understood."

Rosen thought for a moment and said, "Then prepare a batch as soon as possible, as many as possible, at least 200 bottles."

This potion is enough to become his trump card to defeat the rebels.

"no problem."

Rosen was very satisfied with the unexpected new trump card.

Just as I was about to leave, I heard Wei Ge say again.

"Lord, if you want to mix the Hero's Anthem, the improvement of the Iron Potion will have to be postponed."

"It's okay. The hero potion is more important right now."

Rosen was not disappointed at all. He now felt that this court potion master was a real treasure.

After leaving Wei Ge's alchemy room, he immediately went to the weapon refining room of the Kao mages and found that the progress of the Lightning Torrent Crossbow was also very good.

It is estimated that the first batch of finished products will appear in half a month.

This Lightning Torrent Crossbow is his second trump card.

After a few words of encouragement, he finally came to Alonso's refining room.

Alonso also recruited several local apprentices from the island as assistants. When Rosen arrived, he was carefully debugging various refining equipment.

After seeing Rosen, he was delighted: "Lord, this is the best alchemy equipment I have ever used. The performance is surprisingly good."

Seeing that he liked it, Rosen was also very happy. After a few pleasantries, he got down to business.

"I have an urgent job on hand to deal with the threat from the rebels."

Alonso immediately became serious.

"My lord, please give me your orders."

"Crash~"

Rosen handed over the transformation refining book of "Intermediate Lightning Amulet".

"I will provide you with sufficient materials, and I hope to create a batch of induced defense amulets as soon as possible."

Alonso took the weapon refining book, quickly glanced through it, and smiled: "If you use Transfiguration, it's not difficult. I can make at least 30 amulets a day."

He has been studying transfiguration alchemy for some time, and has become quite proficient in the transfiguration and refining techniques of some low- and medium-level magical instruments, and has gained a lot of experience.

"But to charge the amulet, we need to ask other mages for help."

"Don't worry about recharging. I have a way. I need a batch of these amulets. The more the better. At least no less than 300."

This is business, Alonso immediately assured: "I will get it out as soon as possible."

"Very good, if you have any requests, just tell me and I will do my best to meet them."

Alonso shrugged. "Apprentices. I need a group of smart and capable apprentices. It would be best if they have a basic knowledge of refining equipment and can help me with the work right away."

"Okay, I'm going to Shire County to recruit."

Alonso grinned: "Uh-huh ~ civilians, because they are smart and hardworking."

"no problem."

This way, we have the third trump card.

After leaving the weapon refining room, Rosen went to find Knight Commander Codlin.

To be more precise, it was to meet the forest spirit prisoners of war.

He will be of great use to these prisoners.
