Although the decision was made to use these shadow crystals, it was also a matter of time and place to use them.

That huge amount of dark energy can easily cause alarm and misunderstanding in others.

At least in this refugee-filled Hand of Tyr certainly can't be used at will.

Even Sylvanas and Medirri and the others could not tell them, after all, if such a dark matter was revealed, it would likely lead to the hostility of the entire human society.

"You have to find a safe and hidden place...... Su Chen thought to himself, but he immediately thought of Illusia in the Alterac Mountains, that inaccessible snowy mountain can be regarded as hidden, and the Barov family is now absolutely loyal to him, and his entire family is already undead, it can be regarded as dark anymore, and he will never reveal his secrets.

However, when he thought of Illusia, Su Chen couldn't help but feel a little worried.

"I don't know what happened to Illusia and those refugees in the mountain range...... Su Chen originally wanted to use the Book of Returning Medivan to ask Dalaran for food, but now that the Undead Scourge is concentrating its forces to attack Dalaran, even the floating city of Naxxramas has been dispatched, and it is estimated that the plan to transport food from Dalaran has also come to naught.

In that snowy mountain, there is no food, so you can only wait for death.

"It seems that the only way to return those refugees is to the north." Su Chen sighed secretly, although the north is also difficult now, it is not enough to freeze and starve to death.

Moreover, Illusia's management of refugees is also good, perhaps she should come to Tyre to manage these tens of thousands of refugees.

After all, there are many elite warriors and knights around him, but with the increase in refugees, there is an extreme lack of administrators, and these positions should have been held by those noble officials in the past, but at the beginning of the undead raging, the nobles were the fastest to escape, and now the resettlement of these refugees in the hands of Tyr alone has made it difficult for him to cope.

Su Chen didn't leave immediately for the Alterac Mountains, but first laid out the development plan for the Hand of Tyr, after all, this was his base in the Eastern Plaguelands, and it was also the hope for rebuilding Lordaeron in the future.

If Akmund can come to this world, then the history should not change much, and once Akmund is defeated, Illidan will start to act against the Frozen Throne, that is, when he will fully counterattack the Undead Scourge and recover Lordaeron.

It's just that those plague-ridden places are uninhabitable in the short term, and they can only try to create new settlements.

If Akmund can't come, let alone have enough time, he can unite with Dalaran and the other human kingdoms to expel the undead scourge.

But it also requires a new territory......

In addition to trying to reclaim the town of Nanhai and the Silverpine Forest, he also aims to open up large areas of primeval jungle around the Plaguelands as arable farmlands.

"I've seen it in the vicinity by griffin, and if all the thorny jungles behind Tyr's hand are reclaimed as farmland, it will be enough to feed fifty or sixty thousand people, and a little savings should barely sustain the lives of the refugees now, and we can also build a harbor, trade with many human kingdoms in the south, buy food, and even travel by sea to Hinterland, where most of the place is now occupied by ignorant trolls, and we can build a new Lordaeron there."

Su Chen summoned all the officials and generals in the city of the Hand of Tyr, and compared them to everyone on the map, compared to crossing the endless sea to Kalimdo to open up the wasteland, Hinterland, which was close at hand, was a better choice.

In the past, Lordaeron, with its vast plains, would not have looked down on a jungle-covered land like Hinterland, but now everyone saw any territory that was not contaminated by the plague, and their eyes turned green.

After finally making arrangements, Su Chen flew to the Alterac Mountains alone on a griffin.

On the majestic snow-capped mountains, the cold wind blows on the face when flying, which can almost freeze people on the spot, but fortunately, the griffin, as the overlord of the air, has a strong enough flight carrying capacity, and carrying a large box of shadow crystals does not affect its flight speed too much.

With the accurate positioning of Zhi Brain, Su Chen quickly found the valley where a large number of refugees were hidden.

He was worried that these refugees would not be able to withstand the cold of the snowy mountains and leave, but when he entered the valley, he found that the number of refugees was a little more than the last time he came, and there were many newly built wooden houses to shelter from the wind and cold, and there was even a militia team of hundreds of people patrolling the valley.

"Your Highness, why are you here?" Illusia immediately showed surprise after seeing Su Chen.

"Dalaran seems to be about to go to war again, I'm worried that you won't get food, so come and see, the situation in the north is a little better now, if you can't stay here, you can return to the north."

Illusia hurriedly replied, "Your Highness don't worry, we have already obtained enough food, Miss Gianna personally brought a large amount of food immediately after returning to Dalaran, and my father and they have broken through several hidden bases of the Syndicate in the mountains and forests, and have also obtained a lot of food, which is enough to support us for several months." ”

"Oh, I didn't expect Gianna to move quite fast, so I'm relieved, huh...... You seem to be much stronger? Su Chen just breathed a sigh of relief, but immediately looked at Illusia in some surprise.

Under the prompting of Zhi Brain, her physical fitness has almost doubled compared to before!

"I ...... Your Highness, I'm really sorry, I used the summoning magic on the Book of Medivan out of curiosity......" Illusia's face turned pale, and she immediately lowered her head.

"Summoning magic from the Book of Medivan? Then you...... What was summoned? Su Chen couldn't help but be stunned when he heard this, it seemed that most of the records in that book were summoning demons!

"Yes...... It's a demon. Illusia's voice was almost as thin as a mosquito.

"I know, what kind of demon?" Su Chen asked with some curiosity.

"It's a succubus, she's gone, but we signed a contract, and my body has undergone some changes." Illusia spoke, but her face suddenly turned red.

Su Chen quickly discovered her so-called changes under the prompting of Zhi Brain, in addition to the great increase in the defense of her body, her body has also become a lot plump, especially the two beautiful things on her chest, which can hardly be restrained by her dress, and it seems that she will jump out at any time.

"Summoning demons can still have such benefits......" Su Chen couldn't help but be a little speechless about this, and he had some small expectations for the so-called succubus in his heart.

"My subordinates have summoned demons without authorization, and I hope His Highness can forgive them."

"Forget it, just use it when you summon it, but can you still use the magic you used before?" Su Chen asked with some concern, since he had let her read the Book of Medivan, he naturally wouldn't care about this, but if there was one more new surgeon, but because of this, there was one less archmage, it would be a big loss.

Illusia hurriedly shook her head and said, "That demon contract has no effect on my previous magical abilities. ”

"Oh, that's good, by the way, I'm going to do a secret experiment, and I need a place that is absolutely safe, where is the safest place for you?"

After a moment of silence, Illusia immediately said, "The safest ...... It was supposed to be the cave where my father and the others lived, it was originally the cave of the Alterac Yeti, which was originally as complex as a labyrinth, but was later occupied by my father and them, and now it has a lot of magic traps, and it is very safe. ”

"Okay, then you can take me over for a while." Su Chen nodded.

Along the way, Illusia didn't ask Su Chen what was in the box, which also made him quite satisfied, if Sylvanas and Medirli were so obedient, then his life in Azeroth might be extremely comfortable......
