Chengmu was not very old, he was only thirty years old at the time!

For the people of the Purple Gold Continent, thirty years old is not too old, especially among the martial artists who practice martial arts and are successful, the age of thirty is just the age when they have just graduated from the school or have achieved something at a young age!

Not everyone is as lucky as Gu Yi's command, with peerless martial arts secrets and extraordinary qualifications that go directly to the heavenly court! More people are just exploring, exploring the path of martial arts and their own martial arts.

From this point of view, Cheng Mu can be regarded as an extraordinary genius! However, at the age of thirty, he has achieved the strength of the peak of the grandmaster level, and no matter what force he puts in, he is the object of key cultivation.

But Chengmu was unlucky! Because what he cultivated was not some advanced martial arts, but the lowest level of external skills in the Purple Gold Continent!

It's not that Chengmu doesn't have the qualifications to cultivate internal strength!

In fact, when Wu Wuji saw Cheng Mu, he still sighed that he hadn't met him earlier, otherwise, he could have taken advantage of his young age to transfer to internal strength, and his achievements would definitely not be smaller than now!

It's a pity that no matter what world is, there is no 'regret' and 'maybe', as long as things are done, they must bear the result and cannot be changed!

In order to be able to eat a bite of food, Cheng Mu joined a very small gang, and practiced the lowest level of external cultivation of the Terran in the Purple Gold Continent, and this practice was ten years long, knowing that the muscles and veins were formed and the bones were cast, and he became the first master of that gang!

Before the gang could use Chengmu's martial arts to expand outward, the 'Hidden Dragon Society' came up and absorbed them after spending some means.

As a good master of external skills, Cheng Mu was assigned to Wu Wuji's command and became Wu Wuji's closed disciple!

With Wu Wuji's complete set of external martial arts cultivation methods, Cheng Mu can be regarded as a fish in water! He quickly broke through the shackles that had plagued him for many years and walked on the correct path of martial arts! However, after two or three years of hard work, he entered the realm of a grandmaster and became a master in this world!

It's a pity that external strength is external strength! Since the Heavenly Dao of this heaven and earth supports the cultivation of internal strength, the achievements of external martial arts cultivation are placed there, and it is really difficult to make an inch of progress in the back! Unless one day, the external martial artists can truly return to their roots, turn from the outside to the inside, and be recognized by heaven and earth, otherwise they will always be pressed on the head by the internal martial artists.

It's a pity, how can the shackles of heaven and earth be so easy to break? Even for a bug-like character like Gu Yi, the external martial arts summed up are at most at the realm of the Great Grandmaster, and there is really nothing he can do to step forward!

After all, Gu Yi is a martial artist of internal strength after all, and he really has no research on external skills, let alone creating a secret book of external skills that can reach the top!

This is the case with Cheng Mu, although he can be regarded as a rare genius in terms of combat strength and talent!

But even so, Naruki is now very satisfied!

A street child who used to have no food and no clothes to cover his body can grow up to the point where he is now, and Chengmu does not feel how miserable it is. Although his master always sighs that he has a sense of going astray, as a relatively easy to satisfy Chengmu, everything is fine!

Today, Cheng Mu is already one of the disciples under Wu Wuji, holding a team of eighty or ninety thousand, and he can be regarded as a master!

As the most intelligent person among Wu Wuji's disciples, in fact, Cheng Mu discovered a long time ago that his master had been deceived!

And all this, after Cheng Mu said it to his master Wu Wuji for the first time and was severely refuted, Cheng Mu never mentioned it again!

Cheng Mu seemed to feel that his master Wu Wuji didn't know it, but deliberately didn't admit it! It seems that in Shizun's mind, this is not a conspiracy, but a battle for the belief in his heart!

Anyway, Cheng Mu finally decided to stay there with his master, resist the army of Empress Zhao Min, and fight for the belief in his heart!

Cheng Mu, who has long regarded his master Wu Wuji as the closest person in the world, doesn't care about right or wrong, let alone what kind of result he will face once he fails!

As Wu Wuji's closed disciple, and also Wu Wuji's most favored disciple, and even more so by Wu Wuji, he is considered by Wu Wuji to be the most intelligent person among all his disciples, and Chengmu is assigned the most onerous task: to defend 'Badaling'!

As the core area of the entire stubbornly defended hilly and mountainous area, 'Badaling' is definitely the center and core of the entire stubbornly defended area! Once any place is attacked, 'Badaling' can attack or assist, and it is the most important place in the entire stubbornly defended area!

And in this critical place, Wu Wuji himself did not personally participate in the defense, but taught his most trusted disciple, which can be seen from this!

Being seen as Wu Wuji's brain is sometimes confused, stubborn and lacks adaptability, but he is very aware of his shortcomings and problems.

Wu Wuji knew that if he sat in the 'Badaling', he would inevitably lose 'Badaling' because of his unintelligent mind and temper at any time. Naturally, this strategic location will be handed over to the smartest people under his command!

Not only that, but Wu Wuji also knew that if he just handed over the command to the other party and stayed there, it would be equally impossible for the other party to exercise his power normally! Because once the matter came to an end, Wu Wuji knew that he liked to interfere in orders on behalf of the other party!

As a result, the rule of 'Badaling' was completely handed over to Chengmu, not to mention staying in 'Badaling', and even he stayed away from the front of the army led by Zhang Wuji!

For this, Chengmu is naturally grateful, he is very grateful to his master for his trust, for which Chengmu made a heavy oath to live and die with 'Badaling'!

As for 'Badaling', the name is 'Ling', but it is actually a valley with hills and forests.

Different from ordinary valleys, there are not endless towering mountains around 'Badaling', which makes 'Badaling' an easy place to defend and difficult to attack, but the whole valley is surrounded by small and numerous peaks, high or low, making the whole valley become accessible in all directions!

Taking advantage of the topography of 'Badaling', Chengmu established various open and secret posts in key places after careful study, so that every move in the entire 'Badaling' area was in his hands.

In addition, Chengmu broke the conventional defensive concept and creatively adhered to the "Badaling" in the way of "mobile defense", so that others could not figure out the whereabouts of Chengmu and his team.

After seeing the return for the first time, Gu Yi almost thought that Chengmu was a traverser!

After all, Chengmu's fighting method is extremely close to a set of strategies and tactics that Gu Yi knows: guerrilla warfare!

The entire mountainous area of 'Badaling' has become a guerrilla area for Chengmu and his troops, and any team that enters 'Badaling' will gradually wear off from this harassment and frequent fighting!

Breaking the whole into pieces and killing the enemy in a virtual position is the core of Chengmu's tactics! He never fought face-to-face with the opponents who entered the 'Badaling' for the sake of commanding his own troops, but instead used the classic methods of splitting, encircling, harassing, and sneak attacking to defeat the troops attacking the 'Badaling'!

After carefully studying Chengmu's tactics, Gu Yi was basically sure that Chengmu was not a traverser! It can only be said that he is an extremely good tactician, and if he is well trained, he can even become a future military strategist! Of course, judging by intelligence, Chengmu can only become an inconspicuous dust in the history of the Purple Gold Continent!

Why can Gu Yi be sure that Cheng Mu is not a traverser?!

This is because there is a set of mantras that are still fresh in the memory of the Chinese people, especially the Chinese who know a little bit about guerrilla warfare tactics: 'When the enemy advances, I retreat, when the enemy is stationed, I disturb, when the enemy is tired, I fight, and when the enemy retreats, I pursue!'

Gu Yi doesn't remember which revolutionary predecessor came up with this sixteen-character mantra, but it was definitely regarded as the core combat principle of guerrilla warfare!

If Cheng Mu is a traverser, he will definitely remember this sixteen-character formula, and he will definitely do it according to this sixteen-character formula!

It's a pity that Chengmu has achieved 'the enemy advances and I retreat', 'the enemy retreats and I chase', but there is no strategy of 'the enemy is stationed and I disturb' and 'the enemy is tired and I fight'!

What he did was simply to use sneak attacks and surprise attacks to disperse and disperse the opponents who entered the 'Badaling', and then gradually gather superior forces to gradually eliminate the small group of enemies that had been divided!

In terms of function, Cheng Mu has actually achieved his own goal! However, compared with the 16-character formula, Cheng Mu's guerrilla warfare is still very immature, and the damage to himself is also greater, so it cannot be regarded as a truly efficient guerrilla warfare!

Even so, Chengmu's combat talent also amazed everyone in the staff under Gu Yi's command, and he studied Chengmu's combat methods many times, and every time he gave out a praise and exclamation.

Of course...... After Gu Yi made a trip to the General Staff Headquarters and showed off the guerrilla warfare theory he had 'created,' Cheng Mu's guerrilla tactics were no longer amazed by those people in the General Staff! Not only that, but after accepting Gu Yi's tactical theory, he often judged Cheng Mu for not doing well in those aspects.

However, these are just within the staff department established by Gu Yi in the southwest.

Outside, Cheng Mu, as the formulator and executor of this new tactic, has attracted the attention and attention of many people! Empress Zhao Min told Zhang Wuji many times that he must capture Cheng Mu alive instead of killing him! Obviously, Zhao Min is also quite fond of Cheng Mu's talent!

Just when the outside world was admiring and studying Chengmu's tactics, the attack on 'Badaling' gradually unfolded.

Unlike in the past, this time Zhang Wuji did not adopt traditional tactics and send a large number of troops into the 'Badaling' at one time, but found another strange path, and the operational command established outside the 'Badaling' started a plan against the 'Badaling'.

The plan is actually very simple, in Gu Yi's previous life, it was not a whimsical idea on earth, but a combat method that has long been proven to be effective: special operations!

Aren't you flexible? I'm more flexible than you are!

Aren't you secretive? I'm more secretive than you are!

Aren't you haunted? I'm more haunted than you...... And so on, with 'better' to deal with 'excellent', with 'weirder' to deal with 'weird'!

Zhang Wuji's plan was very simple, the team he personally led did not enter the 'Badaling' at all, but assembled and stationed outside.

After that, a number of elite teams with small numbers but strong combat effectiveness were scattered in 'Badaling', and the sixteen-character policy taught by Gu Yi was brought into full play!

In this way of fighting, the team led by Narugi will definitely try their best to eliminate the elite squads that break through and assemble the team. Then, the elite team stationed outside can march! Attack and destroy the gathered enemies with precision!

If the other party disperses again, it will be easy to do! Zhang Wuji immediately withdrew the attacking team and stationed it on the periphery, and continued to let the elite team that broke through continue!

In one word: grind!

The advantage of this is that all of Nariki's strengths will become weaknesses, and the tactics he relies on will lose their effectiveness!

And such a battle made the stubborn personnel who were on the side of the watch and help a little helpless and overwhelmed!

Send troops to the rescue, because the opponent's battle scale is extremely small, it is easy to expose yourself to become a big target, so as to be eliminated by the enemy's concentrated forces!

If you don't send troops to rescue, you can only watch Chengmu's team be eaten away step by step!

This kind of fighting method similar to the fighting method of the U.S. military on Earth against the Afghan guerrillas in the previous life was told to Zhang Wuji by Gu Yi, which made Zhang Wuji immediately feel that his eyes were open!

After all, although the team commanded by Zhang Wuji was not the US military, it was even more superior to the US military! The team led by Nariki was not those guerrilla units in Afghanistan, but was even inferior on the whole!

Zhang Wuji believes that as long as Gu Yi's battle plan is perfectly implemented, Chengmu will definitely be wiped out by himself, and it will be natural for 'Badaling' to take it!

It's just that...... Who will be sent as an elite into 'Badaling' to conduct special forces-style guerrilla warfare?!

First of all, these people must be elites! Real elites! Not to mention grandmaster-level masters, they must also be masters among grandmaster-level masters! If they don't choose such masters, it is really difficult to guarantee that they will be able to escape in the battle of 'Badaling'! After all, they are still mainly hand-to-hand combat, not long-range missiles and bullets!

Secondly, this team must be 'real people'! It is impossible for Zhang Wuji to hand over this exquisite set of tactics to Empress Zhao Min, let alone let Empress Zhao Min find out this set of tactics through her own secrets!

As a keen and intelligent person, Zhang Wuji could see at a glance the malleability of Gu Yi's tactics! To put it simply, he could use the core idea of this tactic as a standard to invent and create more similar combat methods!

In the situation that Gu Yi has not yet unified the human race and is still facing a difficult battle in the future, this kind of exquisite tactical thinking, which is different from the past, must not be spread! At least, the other party cannot be allowed to grasp the core of this set of tactics!

So, after careful selection, Zhang Wuji found the seventy-two people in front of him!
