The next day, after waking up and washing, Sean went straight to the Wood Spirit Circle at the back of the castle, at this time, the War Tree had grown to a height of nearly four meters, and it had begun to show the demeanor of the War Tree Man.

War Tree: Grown from the seeds of the War Tree Man, it is currently in the Mutation Period, and has a chance to give birth to Intelligence. Note: The War Tree in the Mutation Stage can be inlaid with Wood Elemental Crystals of the quality of Thin Wood Crystals or higher, which has a chance to make the War Tree mutate into a War Mother Tree.

"War Mother Tree?" Sean frowned, looking at the information from the identification system, "Could it be that Chelton was hiding something from before?" and deliberately guided me to catalyze the War Tree to transform into a War Tree Man?"

Previously, Sheldon revealed that after the War Tree mutated into a War Tree Man, it could also be seeded through the catalysis of the Wood Elemental Crystal. But now it seems that after the War Tree really changes into a War Tree Man, it will lose its ability to reproduce, and the plan he expects for the War Tree Man army may be in vain.

"It's a good idea, but fortunately, the thin wood crystals have already been prepared. Sean thought a little frightened, then took out the thin wood crystal from the Najie Bead, and just as he wanted to inlay it into the trunk of the War Tree, he saw the wood elemental elves flying towards him from a distance.

"Human, can this thin wood crystal be given to Kiplin, Kiprin will definitely be able to break through the thin wood spar and strengthen his ability. The wood elemental elf looked at the thin wood crystal in Sean's hand with a wistful expression.

Sean shook his head, pointed to the war tree in front of him and said, "This is not good, the war tree needs this thin wood crystal even more at present, but in the future, obtaining the thin wood crystal will be provided to you first." How's the Wood Elemental Crystal Cultivation going?

The Wood Elemental Elf's face stiffened, and he said curtly: "Anyway, the Wood Element Crystal Ore is all to strengthen the concentration of wood elements inside the Wood Spirit Array, so I directly gathered all the wood elements that I pulled into the Wood Spirit Array......"

"That is, there is no wood element crystal ore, right?" Sean looked at the wood elemental elf with an unkind gaze, staring at it unnaturally, and continued, "I hope to ask for my opinion the next time you make a decision. ”

"Got it, I'll tell you next time, it's annoying. ”

Looking at the wood elemental elves who had been hiding far away, Sean inlaid the thin wood crystals in his hand directly into the trunk of the war tree.

The rough trunk of the War Tree seemed to possess spirituality, and soon wrapped the thin wood crystals into the thick bark and disappeared as if they had never existed.

Through the identification system again, the state of the War Tree has changed again, and it is changing towards the War Mother Tree.

War Tree: Grown from the seeds of the War Tree Man, it is currently in the mutation phase, and has a chance to mutate into a war mother tree. Note: None.

"Kipling, this war tree is changing into a war mother tree, is there a way to increase the chance of the war tree's mutation?" Sean smiled kindly and beckoned to the wood elemental elves in the distance.

"Mutation?is this tree really changing, I'll try?" the Wood Elemental Spirit floated in from a distance again, and its form began to change, turning into a rich mass of wood elementals again, enveloping the War Tree in it.

Sean watched the scene in front of him with interest, without the slightest hint of urging, and at the same time, his mental perception began to sense Kipling's actions with all his might.

I saw that Kiprin continued to infiltrate the War Tree through the transfiguration of the wood element, and then constantly re-transformed into the form of an elf, and the two mung bean-sized glasses were full of doubts.

"Human, the vitality of this tree is so strong, and the wood element contained in the thin wood crystals is slowly transforming into the vitality of this tree, which is amazing. As if discovering a new toy, Kiprin continued to explore the reasons for the change in the tree of war.

"Don't get down to business. Sean was a little worried about the child-like Kiplin, and hurriedly reminded. Whether the War Tree can successfully transform into the War Mother Tree is related to the formation of the war tree army on the island in the future, and it must not be sloppy.

Kiprin looked at Sean with a disappointed expression, then nodded affirmatively, "I know the direction of this tree's mutation, I can promote its mutation, but it will deplete my origin." ”

"Origin?" Sean frowned and continued to ask, "Will it cause damage to you?"

"This is not true, as long as you don't lose too much of the origin, it won't cause damage to Kiplin, but Kiprin who has lost his origin will fall into weakness, unless there is a higher quality wood elemental hedron to absorb wood elemental to replenish the source. ”

"I see, I'll send you 1 Alien Wood Crystal later. You promote the mutation of the War Tree first, which is crucial for the entire island, and if there is any need for it, you can also ask me. Sean breathed a sigh of relief, if the damage to the source could not be recovered, then he had to measure the importance of both the Mother Tree of War and the Wood Elemental Elf.

"No problem, wrap it up on me. ”

After receiving Kiplin's affirmative reply, Sean no longer stayed in the Wood Spirit Circle, and prepared to go to the training point and continue to train with the Golden Knights.

As soon as he returned to the castle hall, he was stopped by Joyce, "My lord, you have already reserved a lot of saltpeter that you asked to reserve, you see?"

"Saltpeter?" Sean suddenly remembered, when the overall military strength of the island was still relatively weak, he did plan to prepare some gunpowder and make some explosive packs against those relatively large enemies.

But as the island's military power grew, the idea faded.

He really doesn't have much knowledge of muskets in his head, only knows the simple method of making explosives packs, but at present, the charging power of the Golden Knights is no worse than the power of explosives packs, so saltpeter is a bit chicken, and the output of saltpeter is also very impressive.

"Let's go check it out. Sean soon followed Joyce to the warehouse, which didn't have much cargo inside.

Due to the increasing number of supplies on the island, several warehouses were built on the island again to store various materials, and the castle warehouse is currently stocked with some more valuable treasures.

"My lord, this is all the saltpeter that has been filtered and dried according to your requirements. Joyce said, pointing to a dozen large jars not far away.

"Is there only a little bit of more than half a year?" The production of saltpeter is far worse than Sean imagined, such a little saltpeter, even if it really makes black powder, I am afraid that it can only be made in a few dozen, maybe it will all be used up after a war.

"Do you really want to make ice?" Sean looked at the saltpeter in front of him with some headache, although the consumables for making gunpowder did seem a little small, but if you made ice, the amount was enough.

It's just that the climate of Sean Island is not very hot because of the elemental circle, and the ice is not very useful, "but you can make some delicious ice delicacies through ice." Perhaps after the stock of saltpeter is raised, an ice cellar can be built. ”

The principle of saltpeter ice making is very simple, saltpeter dissolved in water will absorb a lot of heat, so that the temperature of the water will be reduced, so as to achieve the effect of ice making.

The method is also very simple: put the water in a small jar and put it in a large jar of water, add saltpeter to the large jar until the water in the small jar freezes, and then evaporate and crystallize the saltpeter for reuse.

Sean soon summoned a servant, and under his guidance, after dissolving two jars of saltpeter in water, he was given a small jar of ice.

"It's really amazing, I didn't expect saltpeter to make ice?" Joyce looked at Sean commanding the servants with a confused expression, and couldn't figure out what magical thing Sean was tinkering with, but after a small jar of ice came out of nothing, he couldn't help but exclaim.

"Joyce, re-dry this large jar of saltpeter solution, and repeat the previous operation, and you can make a steady stream of ice. Sean paused, then continued, "You tell the chef to try adding ice cubes to juice or milk to make some ice dishes. ”

"Okay, I'll arrange it. ”
