After Yu He's detailed explanation, Gu Juan roughly figured out what the spiritual aperture was opened, and why these people were so obsessed with eating, and even lost all their reason because of this, and became like beasts without knowing it.

In general, opening the spiritual aperture is just a statement, and it is much the same as those Heavenly Machine Mansion martial artists he once brought out who stepped into the Ning Yuan realm, and there is no fundamental difference.

From then on, people can directly try to absorb more heaven and earth spirit elements to achieve the purpose of changing and improving their own life forms.

And this process of change from scratch is one of the benefits of the revival of Lingyuan in the hearts and minds of these smugglers.

The creatures between heaven and earth can be refined, and those with cultivation qualifications will continue to ascend to the sky step by step with the changes, breaking the barrier between immortals and mortals, and striding forward from a spiritless body to a direction that can absorb the spiritual elements of heaven and earth.

And for them, a group of smugglers who have already achieved a little in cultivation, they will naturally get a greater harvest, even an all-round breakthrough and improvement, and lay a more solid foundation and understanding for the future, which cannot be summed up in a word.

However, there are two things that even Yu He is surprised and puzzled about.

First, even if it is a change in heaven and earth and the revival of the spirit element, it will not be like what happened in Wangbei City, and the time for the opening of the spirit aperture to be suddenly compressed to just half a day to be completed.

In this way, no matter what kind of creature it is, it is difficult for the nutrient energy originally stored in the body to support such drastic changes, unless it is in a profound cultivation sect, you can immediately administer pills and spiritual objects, carry out medicinal baths, guide the teacher and other means, and complete the advanced changes without harming the fundamentals, but in Wangbei City, a place where it is difficult to even eat, the above means are simply wishful thinking.

The second is why these people have suddenly become ruthless, murderous and violent, to the point of losing their sanity.

Gu Juan attributed Yu He's first doubt to the result of the combined effect of the golden light and gray mist, and promised that he could let him personally experience the "wonderful" feeling of being illuminated by the sun when he had the opportunity.

The second point of doubt was finally fixed on the body of the demon concubine, believing that it was precisely because of the influence of the blood mist released by the blood fountain that it became the last straw that overwhelmed these ordinary people who suffered from mutations, causing even more unpredictable changes, leading to the irreparable situation now.

For Yu He, who is enthusiastic about his work, Gu Juan can't bear to explain the truth about the changes in heaven and earth that is more real and darker, so as not to dampen the old gentleman's enthusiasm for work.

I have to say that with Yu He's experienced assistant, Gu Juan's research record efficiency has increased exponentially, and all the experimental materials have been analyzed soon, classified, summarized, and recorded, and only a few key research objects can be continued to be observed.

The two of them also thoroughly cleaned up the inside and outside of Wangbei City, whether it was plants or animals that exceeded the boundary, except for a certain number of specimens, the rest were all turned into ashes in the red lotus karmic fire, leaving no traces.

So on the afternoon of this day, after eating the send-off wine of Jiang Chengshou and Zhu Commander, Gu Juan took Yu He's four apprentices and looked south from Beicheng to the south and headed towards the capital of Great Wei.

There was also a team of elite government soldiers, their main task was not to protect a few nobles, but to escort a few steel prisoner carts, from which from time to time came out what seemed to be people, and seemed to be the roar of fierce beasts, so that these government soldiers couldn't help but be frightened, for fear that some monster would break the arm-thick railing and escape from the prisoner car.

After Jiang Tan watched the team of the prince of Zhennan disappear from the end of sight, Jiang Tan let out a low sigh and turned around and walked towards the city.

Commander Zhu of the government barracks followed closely, but he didn't expect Jiang Chengshou, who was walking in front, to suddenly stop without warning, and almost hit him directly.

After standing motionless for a long time, Jiang Tan let out a long sigh and said, "Brother Zhu, when the Chitose Lord left, he did say that he would send a strong army to stabilize the defense of the area around Beicheng, right?"

Commander Zhu thought for a moment and said in a tentative tone, "If you go back to your lordship, Zhennan King Chitose did say so...... So, his old man is a genuine prince with the surname of Da Wei?"

Jiang Tan said very seriously, "Regardless of whether his old man is really a prince Chitose or not, you and I just need to know that it is a thigh that is too thick to be thicker, as long as you and I hug it tightly, there will be a greater possibility of living in this damn situation." ”

"The subordinates understood...... So, how are we going to deal with it when we come back?"

In addition, I must give them a copy of the booklet left by the king of Zhennan, and tell them which plants and trees can be eaten and which ones cannot be eaten, and which ones are best found and directly eradicated by them. ”

After Jiang Tan finished speaking, he was silent again, looking up at the still somewhat gloomy sky, extremely worried about when the powerful army would come, and where should he raise the food and grass for this army of soldiers and horses.

The anxiety and sorrow of the new castle keeper lasted for a long time.

It wasn't until late one night a month later that he was astonished to see a golden-veined war bee the size of a baby's fist in his study, and even more surprised to hear it flutter its wings and make human noise.

"We have come to guard this ground on the orders of Chitose, the king of Zhennan, and hereby inform you to avoid too many misunderstandings. ”

Jiang Tan was excited, sat up straight suddenly, first pinched himself hard, and after making sure that it was not a dream, he hugged his fists respectfully, "Thank you for the grace of His Royal Highness the King of Zhennan, the prince Chitose Chitose Chitose Chitose Chitose ......"

"Xia Guan dares to ask this, this ...... This general, how many soldiers and horses does the army have, and how much grain and grass do you need to prepare?"

"Grain and grass, you don't need to prepare grain and grass...... "The golden-veined war bee said in a flat and straightforward mechanical tone, "The grass and trees outside the city are vigorous, and there is grain and grass everywhere. ”

"This, this ......" Jiang Tan opened his mouth and stammered, not knowing what to say for a while.

He only knew that the big problem of boiling his hair turned a lot gray turned out to be that he disappeared weirdly.

The king of Zhennan, Chitose, is really a god!

................................................

Compared with the revival of the three cities of Wangbei, the northern edge of Gyeonggi has changed much less.

Not only is the wind and snow still blowing, but the temperature is much lower than in other regions under the invasion of the cold snap blowing from the north, and even the animals that have been living here feel the slightest coolness.

In the depths of the low mountains, the dense forest is covered in silver and snow-white.

A hare cowered in the bushes watched its surroundings vigilantly, and from time to time searched and pulled out a few sticks of hay and put them in its mouth to chew, when suddenly the hare's body shrank backwards, and then it ran quickly towards the hole in the dirt where it was hiding.

The sparrows on the branches chirped, and the little gray-brown eyes stared curiously at the creature that had scared the hare away.

It was a man, a woman dressed in a white robe and carrying a brown sword case.

Although she was in the snowy forest, the muddy and slippery roads and fluffy snowflakes that fell from the trees from time to time didn't seem to have any effect on her.

The woman walked slowly through the forest, her white robe was not stained with water, and even the moire leather boots under her feet were clean and fresh, with no traces of muddy water stains.

Looking at the hare that fled in a hurry, the woman blinked her eyes, waved her hand, and a wisp of strong wind popped out, hitting the trunk of the tree in front of the hare with a snap.

With a bang, the hare was smashed by the snow falling from the sky, and it shook the snowflakes on its fur, and plunged into the hole and disappeared with a faster speed than before.

The woman smiled leisurely, ignored the little fellow, and continued to walk in the direction of the southward descending mountain.
