It is difficult to attack the mountain, it is difficult to go to the blue sky, this sentence is now fully reflected in the offensive and defensive battle of Xialu Mountain. Lu Yi had only heard that the defense of Xialu Mountain was very strong, but he didn't expect that this group of guys led by the Venerable Tianquan were so perverted that they actually arranged eighteen defense lines from Xialu Mountain down to Xialu City! These eighteen defense lines were all extremely cleverly constructed, either in dangerous places in the mountains, or in positions across the mountains and rivers, or on high cliffs and cliffs to form a suppression. In short, every line of defense is extremely difficult to break through, and it is the kind of thing that cannot be opened without spending too much manpower and material resources to transform it purely with the help of the natural environment. Not only that, but there are all kinds of small tricks and small designs, and once these are activated, they can really cause a lot of trouble, and as long as the offender does not reach the level of spirit building, it will be a great headache.

On the first day of climbing, the other party suffered a small loss. At that time, when a large group of monks marched through a canyon with a width of fifty zhang to the depths of Xialu Mountain, a team of monks from Xialu Mountain suddenly appeared above the canyon and cut down many century-old vines, and in an instant, countless huge stones fell from the sky. At that time, the high-level monks brought by Lu Yi were all confronting the other party's high-level monks outside Xialu Mountain, and the highest cultivation in this monk army was only in the late seventh-order period, and there were a large number of fourth-order and fifth-order monks, and even more junior monks, their resistance to these boulders was too far, and the canyon was narrow, so there was no way to dodge, so everyone had no choice but to attack those boulders in a hurry to try to break them, although it was also effective, but with little effect. The monks had no choice but to flee in a hurry, and the team was soon divided into several pieces, and many unlucky monks were directly killed and injured by the boulder, and in the blink of an eye, hundreds of them lost their combat effectiveness. And this canyon is one of the several roads that must be passed to the city of Kasumi, there are people to defend here, and there will definitely be other roads, after this group of people hastily withdrew, the news of the ambush was passed to the higher-ups, and the offensive on the opposite side was suspended, and they began to study new ways and means and routes of march.

It seemed that it was not possible to follow the conventional route into the mountain, and two days later, a team of monks above the fifth order once again headed towards the halfway point of Xialu Mountain, and this time, they all adopted the method of flying forward, avoiding the mountains and forests, and adopted the air route. They had a good idea, detouring back to the rear of these ambushed sections, clearing the monks of Xialu Mountain, and then letting the brigade go up the mountain immediately. In the first half of the stage, they marched very smoothly, but after reaching the mountainside position about a thousand zhang above the ground, they felt that the wind in the mountains gradually became fierce, and they got a little closer to some mountains in order to avoid this wind, but there were still a hundred zhang away from the dense forest in the mountains, and countless black birds flew out of the dense forests in the mountains to attack them. These little birds are not big, only half a foot away, and their strength is only equivalent to that of a fifth-order demon beast, but the number is too much, and the black pressure is all over the sky, and while flying, there is an annoying "quack" chirp in their mouths, which makes people's scalps numb when they hear it.

There are birds in front, there is a wind in the back, this wave of monks suddenly fell into a dilemma, those birds were killed a lot by the monks but still did not want to retreat, and finally broke through the defense line of the monks, a fierce fight, the formation of the monks was broken up, and they fell into the dilemma of being besieged under the battle, fortunately, these unknown birds had limited lethality, and finally did not bring fatal damage to these monks, but after a consumption, everyone was exhausted by grinding, and then wanted to move forward is not possible, so they had to retreat in embarrassment.

In this way, after trying several ways to enter the mountain, the attacking side finally realized why Mt. Kasumi was so famous and called a paradise of refuge. Before there were enough high-ranking monks to contain the high-ranking monks who were holding Xialu City so that other high-level monks could free up their hands to help those middle and low-level monks, the attacking side was forced to give up the plan to enter the mountain, and instead began to besiege Xialu Mountain, guarding several key roads into the city and Xialu Mountain, not allowing any monks to enter and leave, and they planned to trap the monks on the mountain.

All this, the people on the mountain were naturally very clear, but after the people of Tianquan introduced some of the defense settings and backup storage of Xia Ju City, everyone didn't take this blockade seriously at all. Because Xialushan has been committed to two things for many years, that is, strategic defense and strategic reserves. As we all know, the composition of the personnel structure of Xialu Mountain is dominated by small and medium-sized families and the vast number of scattered cultivators, this part of the population is the most insecure group of people in the monk world, after they occupied this Xialu Mountain, they have also suffered many invasions, after experiencing countless baptisms of war, Xialu Mountain has finally figured out a set of defense systems suitable for its own characteristics, plus Xialu Mountain has a large number of people who have come and gone over the years, and the experience and practices left behind are also very complicatedThe mountains are full of defenses and traps that I don't know who left behind. Except for a few roads up the mountain that are relatively safe, in fact, there are many crises in the mountains and dense forests, only a small part of these crises come from demon beasts, and most of them come from people who have stayed in Xialu Mountain, so that the residents of Xialu Mountain dare not easily go deep into the mountain forest. Of course, these are all on the mountains below Xialu City, and the mountains above Xialu City are relatively safe, and there are only a few power amplifier arrays and more powerful killing moves, because the number of monks who can attack from top to bottom over the mountainside that is nearly 10,000 zhang high is already very small, at least it must be a monk who can teleport above the seventh order to do it, and against such people, ordinary defensive means no longer work.

In addition to these defensive measures, Xialu City has also been paying attention to stockpiling materials for many years, mainly because of the problem of the resident structure on Xialu Mountain, among the permanent residents of Xialu Mountain, the proportion of middle and high-level monks is actually not much, for example, now, in addition to the seven spiritual monks, there are only a thousand monks above the fifth order, and the rest are below the fifth order or even civilians. Once the war broke out, the city was besieged, these low-level monks and civilians had to eat and drink, so the strategy of digging deep holes and accumulating food was played to the fullest by the residents in the city, almost every family has a deep cellar, with dried meat, food and water and other necessities of life, the monks have prepared a lot of various kinds of pills, healing, recovery, anti-hunger, etc., although it is not too high-end goods, but there are many and variety, which is very suitable for fighting a protracted war. And as the ruler of Xialu City, one hundred and eight chairs are not done in vain, they have also hoarded a large number of spirit stones for the entire city to maintain the operation of the magic circle, and they have collected and manufactured many magic weapons to arm their subordinates, not to mention healing pills or something.

I don't know that once the external forces of Xialu City are connected with Xialu City, this war freak who is not visible on weekdays will show its viciousness and tenacity, often even if Xialu City can't win the other party, it can also use turtle tactics to drag the other party down, and the residents of Xialu City still have a unique skill - we can't beat it, we will go up the mountain! Yes, this time, although the other party has a large number of people, but it has suffered a big loss under Xialu Mountain, it is difficult to attack the mountain, and it is especially difficult to attack Xialu Mountain, it is simply difficult to go to the blue sky!
