The Orc Legion marched in under the leadership of Saruman, and the combined forces of Gondor and the Kingdom of Rohan, as well as some reinforcements from all over the country, failed to stop the Orc Legion's attack.

Even Bion, who had already gathered the Qi field and had a force field shield, joined the camp, but it could not turn the tide of the battle, because Saruman made black powder and popularized its use on a large scale within the orc legion.

The large explosive bag was thrown out by the trebuchet carried by those giant trolls and thrown into the camp of the human alliance, causing only horror in terms of lethality.

The most puzzling thing is that none of the managers sent by the gods to this world have been dispatched, Galadriel is still cultivating the Holy Spirit Fruit Tree in the overseas Immortal Island, and the Ridagaste, who is good at communicating with nature, is also helping to cultivate the Holy Spirit Fruit Tree in the Immortal Island.

The Eagle King also stayed in the old nest of the Misty Mountains to practice the Transfiguration Technique, and Gandalf didn't know that he was studying the Zhou Heavenly Star Fighting Array in that corner, and as for the white-robed wizard Saruman, he even rebelled into the dark camp.

And Zhou Bufan and Xiaobai, the two biggest variables, did not go to the battlefield, and still stayed in River Valley Town to live a semi-secluded life.

Time passed day by day, Xiao Bai was busy exercising the samadhi true fire and spatial displacement, and of course, occasionally practicing the energy transformation technique that he had researched in cooperation with the Eagle King.

As for Zhou Bufan, except for being pulled by Xiaobai to exercise every day, and the dragon soul in the spirit jade talisman under the occasional sacrifice, almost all of them are tired of spending time in the laboratory.

There are two research and analysis projects, of course, the super ion thruster is just for the sake of changing the brain, and the main direction is still the space storage device.

After months of research, there has been some progress, as long as enough light from the sacred tree is fed, it is already possible to store a copy of air in the storage space and restore it, but trying to store solids or liquids will still cause the space field to collapse.

Of course, it can already store and restore air, and it can also be said that the direction is right, but what is missing is that the light of the holy tree and the strength of his own spiritual power are not enough, and this may be solved with the assistance of a special rune array.

It's just that it's too difficult to design a new comprehensive formation with no basic technology in a short period of time, so it's almost impossible to get a space storage device before leaving this world.

However, in the past few months of research, he has also created an additional magic method, using spiritual power to pull and gather the energy of the Divine Crystal (pseudo), space gem, and the light of the Twin Sacred Trees, which can forcibly open a space-time rift, and involve the enemy in it for space-time exile.

Of course, this is only a theoretically feasible means, and it is still difficult to control the opening of the space-time rift, and the space-time rift that opens is very small, and can only banish small insects such as mosquitoes and flies.

However, if you can open the space-time rift with high precision, you don't necessarily have to exile the enemy, if you can open the space-time rift from the enemy to achieve an effect similar to the legendary dimensional slash, the damage is absolutely terrifying.

It's just that the opening of the space-time rift is very slow now, and it is difficult to control it with high precision, so this time, the Yuan Slash space-time banishment or something is far from meeting the requirements of actual combat.

In addition, the price paid for casting this space-time exile is also very large, and releasing a single fly can consume more than half of one's spiritual power, and the energy of the space gem will also be consumed a lot of energy.

It's just that after the space gem was stimulated by space exile, its spiritual power extraction was also enhanced by a few points, so after a few experiments, not only did it not prolong the time of staying in this world, but it was shortened.

If nothing else, with the current speed of space gem energy recovery, it will be automatically activated in more than three months to leave Middle-earth.

……

It was another all-night study, and it wasn't until Xiaobai brought breakfast that he found that it was already dawn, and although the ion thruster was only available for research, it took the lead in making a prototype.

It's just that it doesn't look very good, like a large can, 32 cm high, 16 cm in diameter, weighing about 550 grams, the main body is made of Mithril, and it contains a special rune circuit made of multiple high-level formation materials, which consumes 15 grams of high-level formation materials......

"Stop playing with your ugly jar, hurry up and eat." Seeing that Zhou Bufan was still busy checking the large can, Xiaobai deliberately greeted him.

"Wait, I'll try the thrust first."

As he spoke, he quickly installed and fixed the prototype to the table, and then connected a special matching, supercapacitor, which also used 10 grams of high-grade formation materials to create an internal superconducting coil.

Therefore, although the capacitor is very small, it is only a disc with a diameter of 30 cm and a thickness of 5 cm, and weighs no more than 350 grams, but it successfully saves nearly 1,000 kWh of electricity.

As the line was connected and the switch was turned on, the formation in the prototype was quickly activated, and a high-speed energy field appeared.

Under the action of the energy field, part of the air is ionized and moves in the direction of the diffusion of the energy field at nearly 100 times the speed of sound.

As the continuously variable transmission was adjusted, the airflow through the prototype increased......

The spring pointer on the simple thrust detector is also moving little by little, and when the control device is adjusted to 77% energy output, the thrust successfully reaches the maximum detection value of 40 kg of the detector.

Although the maximum thrust cannot be detected, it can be roughly guessed that the maximum thrust of this thing may be about 55 kilograms, and the thrust-to-weight ratio is as high as 100:1......

This result really made Zhou Bufan a little excited, after having this thing, and then mastering the skills of familiar driving, it is not a problem at all, and the speed of what you want to do in the future is quite fast.

"This is the flying artifact that can help you?"

"That's right, with this thing, I can come and go wherever there is air."

"Then can we go out to the battlefield and farm the orcs?"

"Of course not."

"I heard that the capital of the Gondor Kingdom is about to be taken by the orcs, and the orcs have killed many civilians along the way...... Are we really not going to help? ”

"It's really inappropriate for us to intervene in the war over there."

"Why is it inappropriate, you used to see monsters eating people, and you wanted to break those monsters into pieces, and now those half-orcs who are similar to monsters are killing humans, how did you become indifferent?"

"Why don't you think those big guys sent by the gods to manage this world don't intervene?"

"Of course, everyone is busy."

"That's just an excuse."

“…… Could there be other reasons? ”

"Of course, because the kingdom of Gondor was founded by the Númen Norans."

"What happened to the Númenorians?"

"Well, when I usually have time to look at the history of this world, I will understand."

"Why do you look at the history of this world, anyway, you just stay for a while and go back."

"Knowing oneself and knowing one's opponent can win all battles, since you are still in this world, you must have an understanding of this world, otherwise a person who accidentally provokes someone who can't be provoked will have serious consequences."

"What's so great about that Saruman, his parents can't recognize him when I can beat him alone, and as for those orc armies, although they can use gunpowder, why are they even brushed the devil's aircraft cannons, and they are afraid of the explosives bags of the orcs?"

"Of course Saruman doesn't have to worry, and those orc armies can't worry about it, but we really can't afford to mess with the people behind this incident."

"How good is Sauron?"

"Sauron isn't that powerful, but it's obviously not Sauron who is behind the scenes."

"Could it be that the gods in the Void God Domain?"

"What do you say?"

"Can't you?"

"Everything is possible, and it is also that the Númenorians of that year were too ignorant of life and death, and after defeating and capturing Sauron, they thought they were invincible in the world, and at the instigation of Sauron, they directly launched an expedition to the Void God Domain......"

"So the orcs attacking Gondor is just a means for the gods to kill people with swords, in order to eliminate those ambitious Numanurs?"

"Kill the restless Númenoreans, and finally send a savior to save the survivors and rebuild their homes, easily remove the threat and gain a firm faith, and the gods are still high, still uncomprehensibly righteous and kind."
