423 Forbidden Land
Cliff Mountain.Inside the Dragon and Tiger Mountain Gate, except for Zhang Yan's time of retreat, the disciples in the mountain can wander around at will, and there is no such thing as a forbidden area.

But ever since Zhang Yan went to Xiyuan County with a huge umbrella and came back again, a place on Duanya Mountain has been set aside as a forbidden area.

The three apprentices were very curious, but Zhang Yan didn't explain it to them, no matter how curious they were, they could only hold it in their hearts.Just remember not to trespass in the forbidden area.

Of course, Zhang Yan didn't think that the forbidden area could be worthy of its name only by self-consciousness, and it still had to rely on the magic circle as the actual restriction.

For this reason, Zhang Yan not only set up several magic circles for isolation, but also implicated the magic circle of the Duanya Mountain on the magic circle in this forbidden area. If something goes wrong, the mountain protection circle can be used as an external force make up.This shows how much Zhang Yan attaches importance to this forbidden area.

Can't ignore it.The forbidden area is the place drawn by Zhang Yan to place "Swallowing Mountain".However, Tunshan is filled with "balls" creatures from other lands, and a negligence will cause big trouble.Not everyone in this world can easily handle this strange creature of pure energy like him.

But some problems still existed, and they were not solved because Zhang Yan marked the forbidden area and grabbed the "ball" together with Xuanshi Mountain.

For example, the placement of Xuanshi Mountain.

Once the Xuanshi Mountain escapes from the space gap of the Tunshan Mountain, the properties of the Xuanshi will soon turn the area around the cliff mountain into a barren land.Moreover, the volume of Xuanshi Mountain is not much smaller than that of Duanya Mountain. It is extremely abrupt to put it on the side, not to mention that it is entirely possible to completely destroy Duanya Mountain, which has been raised with great difficulty for the first time.

This problem has been blocking Zhang Yan, anyway, he has not thought of the most suitable solution until now.It's not that there is no way, there are, and there are more than one, but there is no way to realize it immediately, and the details need to be carefully polished.

The first method is that when Zhang Yan searched for ideas from the pavilions in Wanxiangzhuli when he was thinking about the Tunshan Umbrella, he rummaged through the space-like magic circle, and found a kind of space-stretching type that is further than the storage space. array.

There is a saying about this kind of magic circle: even a square inch can be as wide as the world.

There are many twists and turns in this formation about the formation and space, but the essence is actually the same as the storage space, which is to delineate and use the gaps in the space to achieve the function of opening up a similar independent space that can be used.

It's just that compared with the storage space, the biggest change of this kind of space-stretching magic circle is to make a limited interaction between the space gap and the normal space, forming a stable passage that can enter and exit normally and will not have adverse effects on living beings. .

To describe it, it's like you push open a hut, and when you go in, you find that the space inside the hut is larger than a mountain.This kind.

As I said before, there is no room for living beings in the storage space, even a powerful monk can hardly stay there.And this kind of space-stretching magic circle can solve this problem.

Just from the sound of it, this kind of stretching space magic circle is much more subtle than the storage magic circle, and it belongs to the deeper use of the space cracks in the world.But at the same time, the difficulty and threshold of setting up this kind of magic circle is much higher than that of the storage magic circle.The most important thing is a necessary material for array formation that is called "rare in the world" even in the era of earth legends: the empty stone.

Almost all places in the space stretching circle that are different from the storage space circle need to use the Void Cracking Stone.It is also this kind of magical array material that can make normal space and space gaps interact.

It's a pity that Zhang Yan has never encountered the Cracking Stone, which has long been extinct on the earth, in the wild world.

This thing is different from the search for the main drug of the treasure pill Jieling Butian Pill that Zhang Yan has been looking for. There is no such thing as "it may be hidden somewhere".Because the characteristics of the cracked stone are definitely not something that can be hidden by "hiding".

Because the characteristic of the Cracking Stone lies in its incompatibility with normal space. It is intuitively seen that once this thing is freed from the shackles of the earth, rocks and mountains, it will float.And even if it is buried deep underground, it will stimulate the underground space all year round due to its characteristics to cause landslides or landslides. In the end, it still needs to be exposed to see the sun to be considered safe.

Therefore, there is no record about the cracked stone in Huangtianyu now, so Zhang Yan has no confidence in whether he can find this kind of thing.

If there is no cracking stone to build a large array of space expansion, the usefulness of the outer creature "ball" can only be put aside for the time being.At the same time, Zhang Yan was also trying to use the things in his hands to come up with a new idea.

For new ideas, it is up to Zhang Yan to figure out and innovate by himself, and there is no way to find ready-made ones from the existing classics of Taoism.But once it is figured out, it will not be restricted by the lack of the cracking stone, and it can also solve the problem fundamentally.

The idea of ​​the new method is to use the huge Xuanshi Mountain's surplus Xuanshi resources in the Tunshan Umbrella, and then use his pill fire to refine a new "nest", as long as it can be loaded with "balls".As long as the volume of the mysterious stone is no longer as huge as the mountain, the characteristics of the mysterious stone can be restricted, and there will be no excessive influence on the surrounding environment.

It is even more practical to re-establish a home for the "round ball" than the cracked stone that has never been found.

Just when Zhang Yan ran between the cliff mountain and Langyuan city with peace of mind, and returned to his peaceful practice days, the changes in Xiyuan County were constantly changing.It even became more and more violent, and even the Nanyuan Kingdom had to directly throw in the [-] forbidden troops that were originally used as a backup in the past.The purpose is to keep an eye on the place of mutation as much as possible, and don't want to eat meat, but every mouthful of soup can't be less.

Naturally, the reason why Nanyuan Nation was so nervous was not only the change in Xiyuan County itself.If there are all mutations like Xuanshi Mountain, appearing and disappearing, leaving a deep pit, this kind of mutation will be seen by Nanyuan Kingdom, not to mention the use of the five thousand forbidden troops in reserve, even the troops of the West Route Army People and horses will not look twice.

The change in Nanyuan Nation's attitude did not come out of thin air, but because of real, tangible benefits, and it was a benefit that could greatly enhance the national strength of Nanyuan Nation.

For example, a fruit that has never been seen before was found in a mutated place, and it was taken back to be studied by a doctor. It was soon discovered that it can be used in livestock breeding, which can double the speed of poultry such as chickens and ducks. many!It also has obvious effects on large livestock such as pigs and cattle.

Another example is a pebble-like stone. After being crushed and added to the blast furnace, it can increase the toughness of steel by [-]% to [-]%, greatly improving the practicality and durability of weapons.

But these two things are already enough for the high level of Nanyuan Kingdom to attach great importance to it.Not to mention that there are some plants that may increase the strength of the warrior's muscles and bones like Yushan fruit, which makes the senior officials of Nanyuan country ecstatic.

Of course, Nanyuan Kingdom is not just willing to drink soup, but has already begun to actively participate in the exploration. It is in a situation of mutual competition with the Yaozu, but there is no real conflict.

In fact, it wasn't just that Nanyuan Kingdom was nervous about these good things and didn't want to miss them.The spies sent by various countries to Xiyuan County are also thinking about how to let the power behind them also intervene.

But it is in this fiery atmosphere that few people notice some changes that are actually closer to their side.

For example, when Zhang Yan returned to Langyuan City several times recently, he felt that there seemed to be a lot of tyrannical atmosphere in the martial arts academy in Langyuan City. The dean Liu Renchuan disappeared, and replaced him with a new face who was much weaker than Liu Renchuan. Succession.
