Sane helplessly smiled at his mate, then used his Divine Energy to create a high-heat lightning sphere, suspending it above the saltpeter water pot. The water in the pot evaporated quickly; Kaelen stared intently at the pot, timing it perfectly for Sane to promptly retract the sphere.

Saltpeter crystals that needed continuous stirring for a whole day and sun-drying for a night were now obtained in just a moment. Kaelen used a ceramic jar to scoop all the saltpeter into it, washing the stone pot clean.

He turned on the camera, beginning to talk endlessly about how to make ice.

"After having saltpeter, we can make ice. First, everyone prepares for me a thick wooden or stone basin and a smaller ceramic basin, the basin wall must be a bit thinner than a normal ceramic basin."

"Place the small basin inside the large basin. Pour clean water used to make ice into the small basin. Pour normal water into the space between the two basins, then pour a large amount of Saltpeter into the water part in the outer basin and stir evenly..."

Sane stood on one side staring intently at Kaelen’s every movement, then he widened his eyes, watching the water in the small ceramic basin inside slowly freeze into ice. Sane rubbed his eyes, opening them to see the water in the ceramic basin had completely frozen.

Knowing Sane and the video viewers would definitely be surprised, Kaelen pointed at the stone basin, explaining the knowledge once.

Saltpeter was also known as Potassium Nitrate.

When dissolving a large amount of Saltpeter crystals into water, it would create an extremely strong endothermic reaction. This process would absorb heat from the surrounding environment, making the water temperature drop suddenly, even below the freezing point.

Because the outer water had absorbed all the temperature of the water inside the ceramic basin, the water inside could freeze.

Saltpeter, besides its application in making ice and preserving medicinal herbs, was also one of the three main ingredients to manufacture black powder.

Of course, Kaelen would not tell everyone.

This chemical weapon of extremely massive destruction not only caused casualties to humans, but also destroyed the ecological environment extremely seriously. Perhaps later people could tinker and research it themselves, but it should not originate from his hands.

Kaelen lifted the stone basin out, pointing at the saltpeter water pot outside: "Keep sun-drying or re-boiling this water, we will obtain saltpeter again. Therefore a thing like saltpeter is used endlessly without running out."

He turned off the camera, then told Sane to soak the ice basin in spring water to easily separate the ice. The two washed their hands clean, crushed the ice into small pieces then scooped a bowl of sweet soup each, putting ice in, eating while talking. Kaelen handed the sphere to Sane:

"Press the button on its head."

Sane took the sphere, pressing it once. The sphere immediately transformed, returning to its original communication bracelet appearance. He asked curiously: "How did you do that?"

"I integrated the image transmission array into the bracelet, changed the structure a bit, turning it into a ’magical phone’. Tomorrow we return to the Aegis tribe, I will make a few more with image transmission functions, that way later on we can make video calls."

Sane gave a thumbs-up, giving a sincere compliment to his mate, adding another sentence: "Then do you understand the principle of the magical blender yet?"

Kaelen slurped a sip of sweet soup, the cool feeling seeping into his heart and liver. He mumbled: "Not yet, I don’t understand a damn thing about electronics. But imagining those electrical circuits as arrays, I have a bit of inspiration. Waiting to finish suppressing the current chaotic situation, I will try to research it."

Besides the blender, he also wanted to research generators, paper shredders, egg beaters, automatic weaving machines,... As long as he could make one, the subsequent ones would be much easier.

While eating sweet soup, Kaelen reopened the video he just shot to check a bit, then connected with Finnick. Finnick was busy bathing Oliver and Orion, therefore Ryder answered the call for him.

[Papa, this is Ryder. Did you two finish cultivating?]

"Yeah, how are you guys? Have you arrived at the tribe yet?"

[Yes, we have returned for two days already. In the tribe changed a lot, if Papa and Daddy were present here you would definitely be surprised~]

Kaelen chuckled lightly, eating while listening to Ryder chirping about matters in the tribe, occasionally making a few comments.

Sane took advantage of Kaelen being absorbed in talking with his son, secretly adding a bit more sugar into his sweet soup bowl. Sane liked eating sweets, but Kaelen always restricted the sugar amount in food, afraid his father and sons would eat until getting diabetes. If he discovered he secretly added more sugar into food or sneaked milk candies, he would definitely beat him up and down.

Talking for a while Finnick returned; the first thing the boy did was tattle on Zale’s son:

[Papa, Daddy, that brat dared to eye our Orion. Just now he even intended to take advantage of me not paying attention to drag Orion back to his house. Damn it, can’t even walk steadily yet already thinking about snatching Sub-Beasts!"]

Kaelen and Sane almost spat all the sweet soup out.

Sane’s face darkened instructing: "You must watch over the two of them very carefully, any beastman coming close, regardless of having bad intentions or not, just beat them until their fathers can’t recognize them!"

[I got it Daddy, no one will touch a single hair of theirs.]

Finnick seemed to hesitate a bit, then bravely asked: [Daddy, Papa... Is there any news of Ignis yet?]

It seemed the boy was still brooding over Ignis. Sane immediately said:

"Rest assured, Daddy can sense the bloodline connection. At least right now Ignis is still safe, but he is not in the Eastern continent anymore. Papa and I also plan to go to the Western continent next month to take a look."

Finnick breathed a sigh of relief. At this moment Kaelen said again:

"Finnick, do you see the third hole from left to right on the bracelet?"

[Yes. What is it used for Papa?]

"Attach a magic stone containing Papa’s Magical Energy into it, then rotate one circle from right to left, the image Papa sent back will appear. Hand it to Uncle Zale, he will know what needs to be done."

Finnick hurriedly followed. When the boy just placed the magic stone containing Kaelen’s Magical Energy in, the communication bracelet immediately disconnected. This was exactly the inadequacy of the bracelet, only able to use one operation per connection.

The sweet soup had been finished long ago, the couple lay back on the grass resting for a while, then discussed uprooting the whole lotus pond to bring back.

Kaelen clicked his tongue: "If Ryder was here it would be good, directly bringing it all to plant in his spiritual spring. This Fire Lotus losing the nourishment of the Fire God’s Heart only has a little spiritual energy left, completely without any medicinal properties."

Sane rubbed his chin: "We take a few old roots and seeds back to Aegis, then send them through the teleportation array and it’s done. That side is also warm now, no fear of it freezing to death."

Kaelen felt it was also correct, so the couple immediately took action. Mouth saying taking a few roots, but actually wiping clean the whole pond. Fortunately on normal days Sane did not often hoard supplies so his spatial bag had excess capacity to hold this massive amount of lotus plants.

The two uprooted lotuses until nearly evening to finish; not bothering to bathe, they hurriedly carried the two magical beasts lying drowsily, and in a flash appeared at the Aegis tribe gate.

Pity the Fire Bear and the Lightning Leopard, before having time to greet their subordinates, they were carried away by their two masters...
