Due to the existence of the water magic master Tren, whenever the Entagri army makes large-scale transfers, it uses one-way magic portals to move without exception, which is a common practice in the Entagri Empire.

This time, the Entagre army entered the Ofer region, of course, it was no exception, using the magic imprint left by the previous welcome to welcome the return of the hill dwarves, Tren opened the fast passage from Negan soil to the Ofer region, and sent teams of Nttagre troops and a large amount of supplies to Ofer.

With the actions of the Entagre Army in Uffer, the location of the magic mark was also changed as a matter of course, and for the sake of convenience and security considerations, in the end, this magic mark, that is, the exit of the one-way portal, was set in the city of Abaden.

The city of Abaden was an important city of the Kregan people in the Ofer region, this city is located in the western region of Ofer, some distance from the border, but not too far, it is a key point that guards many roads to the western border of Ofer, and is of great military significance.

Before the fall of the Olden kingdom of the Kregan, the fortified city of Abaden had been heavily garrisoned by the Krigans, but in the Battle of Doom, it was broken by the Holy Alliance's Three Kingdoms Alliance and the Elemental Clan, and the city of Abbaden was in ruins.

Now that the Entagre army occupies the Ofer, the main defensive direction is Hammondal, and the dilapidated Abaden City once again highlights its importance due to its geographical location, after all, most of the Entagre army is now deployed in the western region of Ofer, and Chen Jian regards this place as an important stronghold of his own in the Ofer region, because if the exit of the one-way magic portal is located here, it can not only be used as an extremely convenient material transfer station, but also effectively shorten the supply line of most of the Entagre army in the Ofer region, It is also convenient for the troops from Negan to quickly reinforce the defense line in the western part of the city in case of an emergency.

To this end, Chen Jian ordered the rebuilding of the city of Abaden, where a strong military fortress designed by the dwarves is now under construction, and a temporary military camp has been completed, where an army of Entagri is stationed to defend the area.

Every once in a while, large quantities of supplies will be transported there via one-way magical portals, and then transported to the various parts of Ofer for use by the Ntagrean forces stationed there.

It can be said that the city of Abaden at this time was of great military significance to the Entagri army, which had just gained a foothold in Ofer.

It is precisely for this reason that the Elf King ** team that secretly entered the Ofer region regarded Abaden City as their attack target.

Somewhere in the mountains north of Ofer, in a valley where the Elven King's ** team was hiding, the half-elf Gru looked at the few pieces of information in his hand and knew that the time had finally come for him to launch an attack on the Entagri army.

In fact, from the very beginning, the entire battle plan was drawn up by Gru, and the Elven King Parson only proposed a strategic idea for the capture of Ofer and issued specific orders based on the tactics drawn up by Gru.

Of course, the reason why Gru worked so hard was not because of how loyal he was to the Elven Kingdom or to Parson, and now his plan to capture the Ice Sword was unexpectedly thwarted, which made him realize that he might have to rely on the power of the Elven Kingdom for a long time to finally achieve his goal, so of course he did not allow the Elven Kingdom to lose its strength again due to defeat in the next war.

And he also realized that this was a great opportunity for him to further gain Parson's trust and get more power in the elven kingdom, although he was not keen on it, but Parson's trust and more power, especially military power, would undoubtedly help his plan go smoothly, so he didn't mind showing his loyalty and talent to Parson and others at this time.

After carefully analyzing the known information and learning more about the Entagri Empire, Gru set the strategic goal of the Elven Kingdom in the Ofer region to cut off the enemy's magical transportation routes.

Gru doesn't have much talent for learning magic, but that doesn't stop him from mastering a lot of magical knowledge, which makes him very keen to grasp one of the weaknesses of the Entagre Army, which is the over-reliance on one-way magical portals.

There is no doubt that the water-based grandmaster-level magic "Space-Time Dao Landmark", which can use a one-way magic portal to quickly transport between two places, is definitely a very powerful and convenient magic, but of course this magic is not perfect, and it has limitations of one kind or another.

For example, it can only be teleported in one direction, for example, due to the limitation of the magician's magic power, there is a time limit for use, for example, the magic mark must be set up at the exit in advance to be used, for example, the portal must be built at the entrance with a lot of valuable magic materials, for example, if you want to teleport back and forth between the two places, the magician must go back and forth between the two places.

These restrictions, if used wisely, can also be an Achilles' heel.

Gru, on the other hand, was clearly capable of exploiting these limitations as a weakness of the enemy, and he had explained his thinking to Parson in this way at the beginning of the whole plan.

"The Entagri Empire only has one water grandmaster, Tren, which is undoubted information, which means that as long as the Entagri army uses a one-way magic portal, Tren must be used, and in order to be able to teleport back and forth, Tren naturally has to move between the two places."

"And the Entagre army's use of one-way magic portals to transport troops and materials between Negan and the Ofer area is also confirmed information, Ofer is broken, and the Entagre army cannot be supplied locally, and as far as the current situation is concerned, the garrison of the Entagri army in the Ofer region will definitely increase more and more over time, and the amount of materials to be consumed by these armies must be amazing, so we can be sure that the Entagre army's use of one-way magic portals for material transportation will be quite frequent."

"From Negan to Ofer, except for the magic portal, the only way to communicate is by sea or through the undersea tunnel built by the Negans, and now there is no sign that the Ntagri army is capable of building a two-way portal, so as long as we can make the enemy unable to use the one-way magic portal, then the Ntagri army in the Ofer region will become a lone army that cannot obtain supplies for a certain period of time, so it is not difficult for us to destroy or expel them and occupy the Ofer area."

Now, Gru's plan has reached a critical juncture.

In order to ensure that they could complete the battle, the Entagre army was deprived of the ability to use one-way magical portals in the first battle, and Gru did his homework.

He sent his most elite Guardians of the Jungle to investigate Abbaden's situation, and asked the spies of the Elven Kingdom to infiltrate Abbaden's area as much as possible, in order to grasp the possible pattern of the Entagre's army's use of one-way magical portals.

This is not an easy task, of course, the Entagri army also guards against the enemy may make a fuss in this regard, and is extremely cautious when using the one-way portal, and there is no fixed time, but Gru is Gru after all, through the calculation of the material consumption of the Entagri army, as well as some unavoidable signs before and after the use of the one-way magic portal, he still roughly grasps the approximate time period when the Entagri army uses the magic portal.

In Gru's opinion, after mastering the time period when the enemy can use the magic portal, in order to make the enemy unable to use the one-way portal, it is necessary to start from several aspects.

Magic user, magic portal, the material from which a magic portal can be built.

One of the easiest ways is of course to erase the magic user of Tren, without Tren, the Entagri Empire will completely lose the ability to use one-way magic portals, but the easiest way is often the most difficult way, the only water magic master in the Entagri Empire who can use the space-time Dao marker is now treated as a national treasure by the Entagri Army, and the strength of its security guard is second only to Chen Jian, the emperor of the empire and several queens of Chen Jian, and he is extremely powerful, and he wants to kill him, The difficulty may be even higher than killing Jian Chen, even if it is surrounded by a large army on the battlefield, because the teleportation in the water magic is really a trick to escape.

As a result, Gru has set his sights on several other areas.

He planned to take advantage of the opportunity for Tren to stay in Overer with the next delivery of supplies, and use the Elf King's ** team hidden in the Overer region to launch a surprise attack on Abaden.

His primary goal was to destroy the one-way magic portal that the Entagre Army had built in advance to return to Negan, and it would take time for Tren to recover his magic power, and it would take time for the one-way magic portal to be rebuilt, so as long as the pre-built portal was destroyed, he would gain valuable time for his next actions.

Then he wants to destroy all the materials that the enemy has gathered in Abbaden, and Gru thinks that the Entagre army will definitely gather all the magic materials needed to build the magic portal in Abbaden for convenience, without these materials, it is impossible for the Entagre army to rebuild the one-way portal.

At this point, Gru can be sure that the one-way magic portal of the Entagri army has been paralyzed in a short period of time, and if the situation allows, he also plans to try to find the magic mark that Tren had set up in Abbaden in advance to destroy it, so that Tren will not manage to escape back to Negan and open the portal from Negan to the Ofer region again to support the local Ntagri army, but this is not an easy task, the magic mark is not inconspicuous, and Gru is not sure how many magic marks the other party has left in the Ofer area, But it's still worth a try, because if it succeeds, the Elven Kingdom's advantage in the Ofer region will be more certain, and the number of magic marks is limited, in case Tren only leaves a magic mark in the Ofer region, then the Elven Kingdom will be lucky.

Of course, this is an ideal situation, and Gru doesn't expect much from it.

Putting down the information in his hand, Gru thought about it again, and finally made up his mind.

"The strength of the Entagrui army, let me Gru personally verify it, if you dare to stand in my way, you will have to pay the due price"
