After a whole day of discussions, the military industrial development plan formulated by the Academy of Military Sciences was unanimously approved by all those present.

This means that Kyushu Province has taken a solid step to defend against the invasion of the Source Beast in 1155.

After that, Jiang Fan returned to the north and decided to bring back the soldiers of the Silver Dragon Army who remained there, and arranged for them to go to Kunlun Mountain and Tianshan Mountain Range to cultivate for a period of time.

Although it was just September, there was snow in the north, and Jiang Fan looked at the gloomy sky, and a trace of uneasiness rose in his heart.

The wind was biting, and the cold air from the Far North sent shivers down the spine of some warriors.

Jiang Fan walked quickly to the headquarters of the Silver Dragon Army and said, "Contact all the soldiers who are chasing and suppressing the remnants of the enemy in the north, quickly!" ”

The soldier on duty heard the words and operated: "Yes! Call the front-line pursuit troops, and please reply when you hear it! ”

After a while, the fighters on duty turned their heads and said: "Report, the signal is somewhat disordered, half of the fighters did not reply......"

"Signal disorder?!" Jiang Fan was startled, rushed out of the house, and rose into the air.

At a height of 1,000 meters, he saw that the clouds in the northern sky, with a thickness of tens of thousands of meters, were slowly advancing like giant mountains.

Clouds cut across the heavens and the earth, as if to submerge the world.

"Commander-in-chief, the Meteorological Bureau is in an emergency!"

A voice rang out over the communicator.

"A super strong cold air has been detected heading north, and the average temperature in Kyushu is expected to drop by 15-20 degrees Celsius!"

"In addition, in the cold air, we found a strong electromagnetic anomaly!"

Jiang Fan took a deep breath and decisively rushed to the north, looking for the warriors who were chasing the remnants of the enemy.

"Evacuate the whole army and return to the border!"

Every time he met a group of soldiers, Jiang Fan asked them to relay this order to each other.

It was fast evening and the wind reached force seven.

There was a sharp whistling sound between heaven and earth, and Jiang Fan flew over Siberia to contact the command headquarters.

"How's it going, how many people have gone back?"

After a shrill electric sound, there was an intermittent response.

"Thirty-seven king-level warriors and more than 20,000 warriors are all on the way back, and the receiving troops have been dispatched!"

"Good!" Jiang Fan breathed a sigh of relief.

He raised his head and stared at the boundless clouds beneath the deep canopy.

"What's in there?"

"How can the movement of cold air produce electromagnetic fluctuations?"

The silver dragon battle armor covered the whole body, the Hongmeng Heavenly Thunder filled the body, and Jiang Fan flew towards the clouds.

"I'm going to go into the cold air cloud detection and keep in touch on the highest-frequency military channel, except for the second elder Hua Yang, who has reached the demigod, no one else can enter the clouds, over!"

These were the last words of Jiang Fan received by the command in 1152.

The clouds looked like they were right in front of him, but they were actually hundreds of kilometers away from Jiang Fan, and when he really approached the clouds, the clouds didn't look like clouds.

Because in the field of vision, the gloomy clouds all over the body cannot distinguish between heaven and earth, and it is impossible to distinguish the clouds.

"Temperature, minus sixty-seven degrees Celsius!"

Jiang Fan looked at the outside information in the combat horizon and frowned.

"Before entering the cold air cloud, the temperature is so low, and after entering, it will be even lower......"

"To go in or not to go in?"

Jiang Fan thought about it.

"The appearance of this cold air cloud is too strange, although the global temperature has dropped before, there has never been such a scene, and there is no such thing in the memory of the previous life......"

After hesitating, Jiang Fan suddenly saw a flash of blue light in the clouds.

The blue light was like a sword mark, perhaps huge, slashing diagonally down from the upper right.

Although it was only for a moment, Jiang Fan's heart trembled fiercely.

The breath of the sword mark is familiar and unfamiliar!

He was stunned for a few seconds, then suddenly took out the Xuanyuan sword, raised it, and compared it to the direction where the sword light had just appeared, his eyes were shocked.

It's familiar, because the sword marks seem to be left by the Xuanyuan Sword!

And the strangeness is because the power of this sword mark has never been seen in the world, ancient, wild, and powerful!

Jiang Fan swallowed his saliva, and his heart beat faster.

"The things in that cloud are actually related to the Xuanyuan Sword?!"

"In other words, it has something to do with my Kyushu Ancient God Ancestor...... Professor Wang Wenjing said that the Xuanyuan Sword should appear in the Ancestor Peak, but my Xuanyuan Sword was excavated in the Jade Bead Peak, and after the Ancestor Peak was dug up in the future, I didn't understand why this sword appeared in other peaks......"

"There are too many secrets on Xuanyuan Sword, and now there are clues." Jiang Fan clenched his fists, knowing that he might have encountered a crucial opportunity, he made up his mind, "In that case, I'll go and investigate, with my combat power approaching the demigods, there shouldn't be any danger, even if there is danger, I can hide in the land of Godrise!" ”

"That's it, in!"

Jiang Fan tried to contact the command center, but the electromagnetic signal was abnormally disordered, and it would take a certain amount of time to send a message to the other party to receive it.

Immediately, Jiang Fan no longer hesitated, and the Silver Dragon Battle Armor sprayed flames, matching its own flying ability, and rushed towards the clouds with a "brush".

Like a drop of water dripping into the sea, Jiang Fan disappeared into the clouds and disappeared.

I don't know how far I flew, my mind unfolded, and I couldn't detect anything, as if there were only cold clouds left in the world.

The outside of the silver dragon battle armor was crawling with layers of frost, and after being shaken by Jiang Fan, it was crawled all over again, and so on.

After feeling a little tired, Jiang Fan checked the time and found that he had been flying continuously for three hours, probably advancing more than two thousand kilometers.

"I don't know what's in the clouds, so I'm on the safe side, and I can't speed up."

Jiang Fan cautiously looked around and continued to move forward.

The long flight finally came to an end after three days.

In three days, Jiang Fan flew enough distance to circle the earth several times, however, he still did not fly out of the clouds.

This proves that this cloud has properties similar to those of another space.

Jiang Fan looked at the land in front of him.

The land was circular, with a radius of about ten kilometers, and there were no clouds around it, as if it was protected by a glass cover.

Within the earth, there was a black low mountain, about fifteen kilometers long and three thousand meters wide, half of which had submerged into the ground.

Jiang Fan saw that at the top of the low mountain, there was a blue ball spinning rapidly, and it released blue light outward, illuminating the earth.

At this time, the communication, positioning, recording and other functions of the silver dragon armor have all failed, and it is obvious that the blue ball is releasing strong electromagnetic radiation outward.

Jiang Fan clenched the Xuanyuan Sword, and the spiritual qi in his body was mobilized, and he slowly fell towards the black low mountain.

Entering the cloudless range of the "glass cover", Jiang Fan's vigilance was raised to the highest.

However, everything works fine.

Jiang Fan continued to approach and saw the blue ball clearly.

Then he froze, the corners of his mouth twitching, and he didn't move for a long time.
