In the Lilliputian world, one ton, or a thousand kilograms of silver ore, can refine five grams of mythril.

Han Dong used fifteen kilograms of sterling silver in the real world to refine, which is equivalent to fifteen thousand tons of silver ore in the Lilliputian world.

The Mithril that was refined was enough to fill seventy-five kilograms of the Lilliputian world.

Seeing so much Mithril, Blue, Ron, and Didlet's eyes straightened.

Mithril is a precious metal material that is essential to the manufacturing of many magical items.

Because five grams of Mithril requires a ton of silver ore as raw materials, plus the processing and production costs, the cost is even higher.

Most of the circulating in the market is Mithril that exists in nature, that is, it is found in silver mines.

The cost of manual manufacturing is too high.

So, it's hard to see so much Mithril at once.

"I'll give you these Mithril to use, and I hope that the transformation of that knife will not disappoint me." Han Dong took the Mithril to Blue and said at the same time.

Didriet preemptively put away these Mithril with the Space Ring, ignoring the stares of the two white-bearded old men, she said, "Thank you Han Dongmian for your giving, we will definitely make the best use of these Mithril and use these Mithril in the most suitable place."

Your sword will be successful. ”

"I'm looking forward to your masterpiece." Han Dong said.

After completing the refining in the morning, he came to the paper mill in the afternoon with the best main ingredients, and finally used the pulp from the paper mill and the main materials provided by Han Dong to complete the production of the first batch, ten tons of sixth-grade magic paper.

This batch of magic paper was processed, and the eyes of the owner of the paper mill lit up.

This kind of paper looks so good, the silver color is very eye-catching, and unlike the silver foil, this silver color has an indescribable appeal.

So he said to Han Dong, "Is this layer all silver?" Is the formula for this paper available to the public? ”

Hearing this, Han Dong said: "This is indeed silver, the cost is very high, I am researching a kind of experimental paper, which needs to be kept secret." ”

Hearing that it was really made of silver, the boss's eyes widened.

Good fellow, this is ten tons of paper, all with a layer of silver attached to the surface, which is too expensive.

It's really not his paper mill play.

There is no market, and a wave of capital difficulties can bankrupt him.

Can't be provoked, can't be provoked.

Those who engage in scientific research are indeed rich people.

"Hehe, then welcome to cooperate next time." The boss laughed.

This wave of OEM made a lot of money, but it was much more profitable than his hard work to make ordinary paper for sale.

"Next time, definitely." Han Dong said.

This batch of sixth-level magic paper is enough for him for a long time, and it is estimated that he will not consider making a new batch of paper in a short period of time.

After all, this thing is really not cheap.

And he is planning to recruit workers recently, which is another expense, and he needs to pay attention to his own financial problems.

After returning from the paper mill in the afternoon and putting the transported paper into the space ring, Han Dong went to the airport.

The itinerary is very full, and he needs to go to the desert poplar forest and get some poplar trees to the Lilliputian world.

It's good to be able to finish it during the day on Sunday and be able to go back to Toyosu on Sunday night.

On the first day of school in the real sense, he couldn't just skip class.

After resting on the plane and getting off the plane, Han Dong directly followed the mobile phone navigation and set off towards the poplar forest.

It was still not dawn, and just in time for the night, Han Dong used the dark stealth technique to enter the depths of the poplar forest.

These poplar trees are used to prevent wind and fix sand, and Han Dong will not just remove them.

Now he has mastered the life-type magic of the eighth order and below.

According to the plan, he needed to use life magic to make some of the poplar trees grow quickly, so as to make up for the loss of the poplar forest's ability to prevent wind and fix sand because of the few poplar trees he removed.

The poplar trees selected by Han Dong were not the tallest, but were between thirteen and fourteen meters high.

Within this range, after being transplanted into the Lilliputian world, they still have some plasticity, and at the same time, they will not be too weak to adapt to changes in the environment.

There are 20 trees in total, selected from different parts of the forest, and then transported one by one.

It's not an easy thing to do.

He needed to wrap an entire tree in his mental power before he could put it in the spatial ring.

Mu Yuanjing's "power" is limited, he can fit up to three trees in it at a time, and then he needs to recharge them.

In order not to cause more damage to the poplar forest, Han Dong could only go to Lilliputia's side to absorb the life force.

This is similar to the slaughter of the Forest of Warcraft by the dark god Garuda.

It's just that Han Dong's relatively "chronic injury" also gave them a chance to live.

After the twenty poplar trees were moved, it was already this afternoon.

Then, he seized the time and chose the same number of poplar trees, using life magic to make their roots thicker and stronger, and the overall size grew a lot.

The poplar tree, which was originally seven or eight meters high, has grown to seventeen or eighteen meters.

Growing a height of 10 meters in a short period of time can increase the overall volume much more.

After boarding the return plane in the evening, Han Dong felt like he had collapsed.

Fortunately, the poplar trees on the Lilliputian side are taken care of by Vera to ensure their survival.

After resting on the plane and returning to the rental house in Toyosu, Han Dong came to the Lilliputian world again.

Now the final step needs to be taken to turn these poplar trees into tree people.

From the magical knowledge given by Eunice, Han Dong learned something about the Treants.

The Treants are a separate race, just like the Orcs.

Originally, the Treants also had a glorious history, but after experiencing the Demon Disaster, they gradually perished due to fecundity problems.

At least on the human plane, that is, on this plane, the tree people have been cut off.

Before becoming a treeman, that is, when they exist as a tree, they can reproduce by cuttings, etc.

But when it becomes a Treant, it loses its fecundity.

As a new species, the Treant has not been able to develop its own unique way of reproduction.

So, basically, the Treants are one less dead.

However, prior to the Plague, Moon Fountain was run by both Treants and Elves, who could rely on Moon Fountain and its unique magic to turn more trees into Treants.

Later, a large number of treants died and were unable to keep the Moon Spring, and the Moon Spring was also damaged during the war, so that it took a long time for the Moon Spring to be used normally, so that the elves did not perish.

But the Treants are really almost dead, and the few Treants who are still alive are hiding in the Elven Forest.

There are not a few big trees left that are suitable for being lit or can be lit and have a chance to become a treeman, so that now, the inheritance of the treeman is almost broken.

And now, the twenty giant trees brought by Han Dong with a height of more than 1,300 meters in Vera's eyes seem to be an opportunity for the tree people to rise again.
