"Is this the Sanctuary?" Looking at the ball-like elves of light dancing in the palm of his hand, feeling the rich energy around him, Yang Qianyu muttered to himself.

Immediately after the Tree of Eternity confessed its Lord, it began to exercise its duties as a servant. According to its own statement, the 'Titanus Protoss' in the primeval period was a race with a high-end civilization, and the 'Tree of Eternity' was an alchemical plant creature created by the Titanus Protoss to provide various aids to their daily life. The total population of the Titanus Protoss is small, and the daily labor force and armament of the soldiers are all sustained by the alchemical creatures created by the Eternal Tree. These alchemical creatures are absolutely obedient to the orders of their creators, and are the ideal servants and subordinates.

And the 'primordial elf' that stopped in Yang Qianyu's palm at this time was the most primitive model form of these alchemy creatures after they were created.

Yang Qianyu threw out the primordial spirit in his hand, causing the green to quickly disappear into a big tree not far away.

"Boom! Boom! ”

The big tree possessed by the primordial elves began to tremble, and then its form changed dramatically in just a few seconds, the original fifty-meter-high tree body was half shorter, and at the same time, the diameter and width of the trunk were tripled, and a huge face and vivid facial features appeared on the trunk, and the thick branches of two ordinary giant tree trunks appeared on both sides of the main trunk, like two arms.

"Dear master, the Ancient Tree of War salutes you." The transformed giant tree bowed slightly to Yang Qianyu, and the mouth of the main trunk face spat out respectful words.

And under Yang Qianyu's exploration technique, the data of the giant tree in front of him was revealed.

'Name: Ancient Tree of War''Function: Fabricate Combat Class''Building Level: Lv1''Productive Class: Swordsman (Initial Level Lv1), Archer (Initial Level Lv1)'

"Are there only two classes?" Yang Qianyu pondered for a moment and asked at the War Ancient Tree, "Are there any other troops?" ”

"Yes." The Ancient Tree of War replied, "When you increase the level of the building, you will also gain the corresponding manufacturing permissions. ”

"Can I improve now?" Yang Qianyu asked.

"Not enough energy." The War Ancient Tree replied, "To upgrade the building level to Lv2, you need 100,000 gold power. ”

"......" Yang Qianyu didn't answer, but he took a sharp breath. …… In that case, let's put the promotion plan on hold for the time being......"

"Any other orders, master?" The War Ancient Tree asked.

"Standby."

"Yes."

After Yang Qianyu gave the order to stand by, the ancient tree of war stopped talking, closed his eyes and stopped moving.

Yang Qianyu sighed after watching the War Ancient Tree enter a dormant state and stand by.

"That's a good thing." I saw Yang Qianyu muttering to herself. "It would be perfect if it wasn't too expensive."

－

After the Tree of Eternity awakened and confessed its Lord, it released its own energy to transform the entire Forest of Giant Trees. According to it, this transformed land was generally called the 'Sanctuary' in the primeval period.

Through the communication with the Eternal Tree, everyone learned about the purpose of the Titanus Protoss to create the 'Sanctuary' in the primeval period.

The Sanctuary, the region rich in world energy, if it reaches the perfect level, its heaven and earth law energy is all in the hands of the controller, it can be said that it will be another world, and the controller will be like the creator god of that world.

For the current traversing people, the role provided by a sacred domain is only to allow the people who inhabit it to gain a small amount of pure energy. Although the energy that can be obtained is not much, it is quite urgently needed for the traversers who have now entered the bottleneck of strength improvement.

At the same time, the Eternal Tree can also build various auxiliary buildings in the Sanctuary for civilian and military purposes. Of course, these buildings can't appear out of thin air. Their construction requires an object that can attach energy as a framework to form.

According to the Tree of Eternity, the most energy-dependent item in the world of Yber is gold.

To put it more bluntly, it is gold - it can be golden sand, gold ore, even gold objects, gold coins, gold nuggets and even precious rare metal magic gold.

After learning about the Eternal Tree's need for the manufacture of outbuildings, everyone couldn't help but be dumbfounded.

"Hey, hey, hey! Isn't this the same as collecting gold coins in the Warcraft game?! Chen Zhanying shouted.

In fact, there really isn't much difference.

However, what the Tree of Eternity needs is not pure 'gold', but the element of gold—more precisely, the 'magic contained in the element of gold', or 'the power of gold' for short.

According to the Tree of Eternity, in the primeval period, the Titanus Protoss measured the power of gold in 'Garons'. And the amount of 'gold power' contained in different gold items is also different. For example, in the southern kingdom of Tristram, where the people are located, the standard gold coins in circulation contain the "gold power" of "0.4 (four-tenths) of galleons" per gold coin. It may not sound like much, but judging by the metal ratio of the gold coins minted in the Kingdom Coins, 'four gold, silver, and five leads' (the metal ratio of a standard gold coin is: 40% gold, 50% silver, and 10% lead), it still fits its proportion. And the magic gold with the same weight as a standard gold coin contains the 'golden power' of '100 Galleons', and the difference between them is 250 times!

And with the value of more than 90,000 gold coins currently owned by the traversers (some of which were spent in a few months), plus the gold tools obtained from several expeditions, it is about 50,000 Galleons when converted into 'Golden Power'.

What is the power of more than 50,000 gold enough to do?

Yang Qianyu summoned a 'free' 'primordial elf' (the primordial elf is a pure energy alchemy creature isolated from the Eternal Tree, of course, the number of primordial elves that the Eternal Tree can isolate each day is limited). Ordered to fuse the 'War Ancient Tree' created by fusing a giant tree, costing 15,000 Galleons of gold.

The types of troops that the Ancient Tree of War can make, sword and shield soldiers and archers, each of the former requires 2,300 Galleons of gold, and the latter requires 1,600 Galleons of gold each.

And these classes also need daily supplies. However, they are not suitable for ordinary food, and rely on the energy-rich well water provided by the 'Well of Vitality' for their survival.

For every 'Well of Vitality' that can sustain the daily energy of twelve alchemy soldiers, it costs 8,000 Galleons of gold......

After some calculations, everyone's faces turned a little dark.

With more than 50,000 Galleons of gold, it is only enough to build an 'Ancient War Tree' and a 'Well of Vitality', and then create less than ten sword and shield soldiers or archers.

Moreover, if these sword and shield soldiers or archers were killed in battle, it would mean that thousands of Galleons of gold power were wasted.

That's a few thousand gold coins, and a few thousand gold coins at most!

Even the king of a country must be heartbroken if he wastes so much gold in vain at once, right?
