The successful formation of the Northern Regions Army gave the Northern Regions the strength to resist the huge legions of the Tianwu Sect with the Qi Training Period and the Foundation Building Period as the main force.

However, even in advanced conventional weapons and equipment, it is difficult to cause great damage to the monks of the Dan and Yuan Infant Stages, so fundamentally, the Northern Regions is still unable to comprehensively confront the Tianwu Sect, which has a huge number of Great Monks of the Dan and Yuan Infant Stages.

Someone in the Northern Regions proposed to unite with the Huayang Sect to fight against the Tianwu Sect, but this is just a fool's dream, what the Huayang Sect currently cares about is only self-preservation, and even if the Huayang Sect agrees to cooperate with the Northern Regions to fight against the Tianwu Sect, but first of all, it must be backed by huge resources, and now the other four domains that are rich are all occupied by the Tianwu Sect, leaving a poor jingling Northern Domain, how can there be a large amount of capital to fight against the Tianwu Sect.

After the high-level of the Taiyuan Sect seriously analyzed the situation of the enemy and us, they all thought that there was little hope of victory in the Northern Regions, so some cowardly factions were formed, and the cowardly factions continued to release their voices, saying that it was impossible for the Northern Regions to resist the attack of the Tianwu Sect, and in order to save the sentient beings in the Northern Regions from the poison of the war, they surrendered to the Tianwu Sect as soon as possible.

This wind of surrender did not float for long, and it was strongly stopped by Zhao Yuanchun, the lord of the Northern Yuan Dynasty, and several leading figures who advocated surrender were killed on the spot.

Han Zi was clear about the worries of the top level of the Taiyuan Sect, and she had also carefully analyzed these issues, but this did not mean that the Northern Regions had no chance of winning, what made her so confident.

It turned out that the atomic weapon that Han Zi was proud of in his heart had been developed, and he looked at the oval-shaped egg in front of him with a diameter of about two meters.

Han Zi thought in his heart that as long as the Heavenly Martial Sect's Transformation God Ancestor did not come forward, those Heavenly Martial Sect's Sect Elders and Yuan Infant Stage Great Cultivators would not be able to withstand the powerful shock wave from the explosion of the atomic weapon, the hot air flow that was much higher than the surface temperature of the sun, and the super strong radiation.

It can be said that in the face of the energy of the atoms, those Yudan and Yuanying monks are just a pile of scum.

Han Zi named the first Origin Energy Weapon Space No. 1 Atomic Energy Weapon.

Han Zi asked Xiao Huang to bring the Space One Atomic Weapon to the Gobi Desert, where the breath of life was relatively dim, ten thousand miles away from Beiyuan City.

And Han Zi also asked Zhao Yuanchun to gather all the monks above the Jiedan in the Northern Regions to a height of one thousand miles away from the blasting center.

Han Zi did this to let these monks above the knot see the power of the original energy, and believed that after seeing the power of the atomic weapon, the overall morale of the Northern Regions would increase exponentially.

There were a total of 248 monks in the Northern Regions, except for a few who were in retreat, and the other 246 were all called by Zhao Yuanchun to a height of 1,000 miles outside the blasting center point.

Although these Jiedan monks didn't know what Zhao Yuanchun had asked them to come for, none of them dared to ask out loud, they knew Zhao Yuanchun's temper.

After Xiao Huang placed the Space One atomic weapon on a black iron shelf hundreds of meters high, everything was ready.

Soon, Zhao Yuanchun released a huge image of the jade slip and appeared in front of the monks present, and they saw a white oval egg placed on a very high iron frame in the image.

In a hidden jungle thousands of miles away, Han Zi, with the cooperation of Li Ying and Xiaolian, completed the final procedure of detonating the atomic weapon, only to see a red sign suddenly appear in Han Zi's hand, and there was a black button in the middle of the red brand.

After everything was ready, Han Zi quickly evacuated the scene through a contract, and about a quarter of an hour later, Xiao Huang and Han Zi converged in the jungle.

"Sister Ying, count down!"

"Ten, nine, eight, seven, six, five, four, three, two, one. ”

"Detonate!"

As soon as Li Ying's words fell, Han Zi pressed the button sign in his hand.

At the moment when Han Zi pressed the button, a shocking bang suddenly sounded over the Gobi Desert.

"Boom... Boom..."

Just when the monks in the Northern Regions were completely ignorant of the rhythm of their daily lives, the earth that suddenly arrived trembled and made them wonder what was going on, could there be an earthquake in the Immortal Cultivation Realm, this was really unheard of.

After the loud noise, a huge fireball rose rapidly, as if a second sun appeared in the sky, the huge fireball formed by the powerful energy burned the sky above the Gobi Desert red, and the mushroom cloud with all the momentum that crushed everything went straight into the sky, and the shock wave generated by the explosion spread rapidly to the surroundings one after another, destroying everything within a radius of thousands of miles into pieces of ruins, and the nearby mountains were flattened in half by the energy impact of the atomic weapon explosion.

All the vegetation and trees within a radius of thousands of miles have also turned into fly ash, and after the atomic energy explosion, there will be no life in the Gobi Desert, which was originally bleak in life, in the next hundred years.

In the sky thousands of miles away from the stall next door, all the more than 200 Jiedan monks who witnessed the explosion of atomic energy couldn't believe the scene they saw, that kind of energy was too terrifying, Mo said that they were such a Yuedan monk is Yuanying Monk will also die in this kind of energy, they are now looking at Zhao Yuanchun with some doubts, hoping that Zhao Yuanchun can solve their doubts, what is going on.

When Zhao Yuanchun looked at the more than two hundred Jiedan monks who were staring at him with Qi Qi in both eyes, he was also shocked by the energy generated by the explosion just now, and he could bet that if he was allowed to survive that huge explosion, he would definitely not survive a quarter of an hour.

What kind of person is his niece, who can make such a weapon against the sky, it is not his niece Zhao Yuanchun, there is another niece, his heart is beating fast at a beat rate of one hundred and eight per second.

Every time his niece will give him unexpected surprises, thanks to his heart's capacity, otherwise his heart has to jump out.

Zhao Yuanchun explained to the Jiedan monks present with a serious attitude that this was his latest super magic weapon refined, which was specially used to fight against the Heavenly Martial Sect.

Zhao Yuanchun said this not to show off himself, but to take care of Han Zi's safety, once Han Zi was remembered because of this matter, which would bring danger to her, in order to eliminate this unknown factor, so he Zhao Yuanchun resisted this matter, because who dared to think about a great monk in the middle of the Yuan Dynasty, did he show that he had lived too long.

After Zhao Yuanchun explained, the doubts in the hearts of the monks present were finally solved, and they congratulated Zhao Yuanchun one after another, and a strong battle intent appeared in everyone's eyes, because none of them wanted to be the servants of the Tianwu Sect, and the monks had the dignity they should have, because there was a magic weapon to help the fight against the Tianwu Sect in the future, and there was no chance of victory.

After the success of the first atomic weapon test, Han Zi also went to the dense forest where the uranium ore was found, and collected a considerable amount of uranium ore, because of the tense situation, Han Zi and her small team once again carried out uranium enrichment and purification for half a year, Han Zi was ready to manufacture three hundred atomic weapons at one time, but this was also the last time to manufacture atomic weapons, and the newly created original energy weapons were mainly used as vehicles to carry atomic weapons by the current ground-to-ground **.

Atomic energy technology is different from other conventional weapons, it must not be announced to the public, because once it is announced, it will definitely not be a good thing for the entire Xuanyuan Continent, Han Zi also specially told the small team members involved in the manufacture of atomic energy, for this reason, the atomic weapon technology must be absolutely confidential, unless it encounters a huge crisis can be used atomic weapons, under normal circumstances, it must not be used, once it is used, it is not only the destruction of the ecology of the Xuanyuan Continent, but also the life of all the living beings on the continent is irresponsible, so what is the difference with those demon cultivators and evil cultivators, this is Han Zi's bottom line, no one can cross this line。

Therefore, Han Zi decided that once she repelled the invasion of the Heavenly Martial Sect, she would destroy the remaining atomic weapons and would not manufacture them in the future.
